Somaliland: Solar Power and Microgrid Intelligence for an Urban Power Grid
DHYBRID Technology Improves Supply Security to City and Port of Berbera
Berbera (Somaliland)/Gauting (Germany), June 22, 2021. As of April 2021, the citywide power grid supplying the city of Berbera, home to the largest port in the area, is being monitored and controlled using DHYBRID microgrid technology. For this purpose, two solar plants with a total capacity of 8 megawatts, a containerized lithium-ion power storage system with a capacity of 2 megawatt hours, and three modern diesel generators were combined in the Berbera Electricity Company (BEC) utility grid. This has enabled BEC to reduce the electricity tariff in Berbera which is now the lowest in the Somaliland and the Somali-Peninsula overall.

With the help of its international partner teams and remote commissioning, DHYBRID was able to complete this large-scale expansion in just six weeks, despite the ongoing pandemic and extensive global logistics challenges.
High Energy Prices and a Boom in Solar Installations
Somalia and the Republic of Somaliland are among the countries with the highest energy prices in the world. The electrical power generation system primarily consists of isolated city grids of diesel generators. At the same time, demand for electrical energy only continues to grow as infrastructure rapidly expands. The port of Berbera, for example, is envisioned to improve the flow of goods to Ethiopia with its more than 100 million inhabitants, and is currently being expanded at a cost of almost half a billion dollars. Additionally, Berbera has its own airports to which BEC also supplies power.
In order to improve the energy supply, more and more photovoltaic power plants are being built in Somaliland to supplement the existing generators, in addition to other measures. But this development poses major challenges for the power grids. “Various generators within the grid must be continuously coordinated, especially when renewable energies are involved. Otherwise, problems with the grid frequency and voltage will become unavoidable, making it impossible to utilize all the available power,” explains Benedikt Böhm from DHYBRID. “It is simply not enough to just consider the solar capacity available. Effective grid management is essential.”
Universal Power Platform Coordinates Decentralized Generators
“The requirement was clear: Berbera needed a scalable energy supply that could be monitored and managed centrally within the shortest time frame possible. The DHYBRID Universal Power Platform has succeeded in both, power quality and grid performance have increased considerably as soon as everything was up and running,” says Ibrahim Yaqub, CEO of BEC.
In fact, Berbera’s overall city grid’s power factor has now increased by 20 percent. This has significantly improved the distribution load bearing capacity and power generation efficiency. Moreover, the discontinued use of large quantities of diesel fuel has made Berbera the largest city powered by renewable energy in Somaliland. What is more, the city now operates the largest battery energy storage system in the country.
BEC now uses DHYBRID’s open-technology Universal Power Platform (UPP) as a process control system and monitors its energy grid with the SCADA system from the very same microgrid specialists based in Germany. SCADA stands for Supervisory Control And Data Acquisition. It is a computerized system for monitoring technical installations.
DHYBRID’s lithium-ion storage system can be operated either alongside the grid or as an integrated part of it. In this operating mode and in conjunction with the UPP, it almost completely eliminates grid instability and disturbances due to multiple effects of growing electrical demand profiles.
This project in Somaliland is one of the first in the world to use DHYBRID’s patented Maximum Inverter Power Tracking (MIPT) technology to increase the share of solar power in microgrids.

DHYBRID installs connected microgrids on 26 Maldivian islands
PRESS RELEASE
DHYBRID installs connected microgrids on 26 Maldivian islands
Central monitoring through a shared SCADA system
Gauting (Germany)/Malé (Maldives), June 8, 2021. Microgrid experts at DHYBRID have installed microgrids on a total of 26 islands on the Shaviyani and Noonu Atolls of the Maldives and equipped them with a central monitoring and control system (SCADA). The project sponsored by the Maldivian Ministry of Environment and the Climate Investment Funds aims to substantially decrease carbon emissions as well as the costs of energy generation on these remote islands. The solar energy capacity installed is about 2.65 megawatts, and the capacity of the battery storage systems used is around 3.2 megawatt hours.

The solar addition to the existing microgrids on both atolls is part of the Preparing Outer Islands for Sustainable Energy Development project, or POISED, which sees to making the energy supply of the outer atolls and islands as well as the region surrounding the main island of Malé sustainable.
Objective: Reducing high electricity prices and emissions
Almost all electricity consumed in the Maldives is generated from imported diesel. The costs for importing energy made up about 20 percent of the gross domestic product in 2016. Transporting this electrical energy to the remote islands and atolls to the south adds to these costs on a local level. At rates of 20 to 70 US cents per kilowatt hour, the electricity prices in the Maldives are among the highest in all of Southern Asia. Plus the diesel systems have high emissions in the form of CO2, pollutants and noise. Photovoltaic installations and battery-based storage units significantly reduce the diesel generators’ run times.
The central energy management system, the Universal Power Platform (UPP), from DHYBRID is what sets its microgrids apart. The UPP dynamically controls all energy flows in the grid, from the battery inverter to the diesel generator. It also continuously measures the grid and storage system parameters as well as the load profiles and prioritizes solar energy whenever possible. Only when the combined power from the PV installation and storage system is insufficient the diesel unit switches on.
The advantages of the new microgrids are immediately noticeable. On the island of Fohdoo, a photovoltaic installation with a power output of 100 kilowatts supplies about 30 percent of the island’s electricity, saving around 35,000 liters of diesel per year. “The generator remains shut off for the majority of the day,” says Abdulla Nashith, Director of the Technical Services and Green Energy Department of Fenaka Corporation Limited, a state-owned utility company which is responsible for most of the southern atolls.
Central monitoring of all 26 islands
The new microgrids are monitored in the utility’s central monitoring stations at Fenaka’s headquarters in the Maldivian capital city of Malé. All 26 islands are centrally monitored by a SCADA system developed by DHYBRID. Access is granted via a secure, encrypted VPN connection. “From Malé, we can monitor energy generation and other parameters on the other islands in real time thanks to the centralized SCADA system. This enables us to respond quickly to any problems that occur,” Nashith adds. New solar-diesel hybrid grids are in the pipeline in the next several years for 69 more Maldivian islands. They will also be linked to the central SCADA system.
In addition to supplying components and connecting the system, DHYBRID also trains local personnel to operate it. “DHYBRID has a wide range of experience, with over 70 projects worldwide. Most of the microgrids in use in the Maldives rely on our technology. We transfer this knowledge to our partners as part of our training programs so that they can continue to operate the installations as efficiently as possible,” says Benedikt Böhm, CEO of DHYBRID.

KATEK increases market share for home storage inverters
PRESS RELEASE
KATEK increases market share for home storage inverters
Memmingen/Germany, 18 May 2021 – Leading electronics service provider KATEK has increased its market share for home storage inverters. Around 30 percent of all energy storage systems with a power output of up to 10 kW sold in Germany in 2020 were fitted with a KATEK inverter.
“With this market share, we are one of Germany’s leading inverter suppliers for the home storage segment. This success also stands for the performance and competitiveness of our development and manufacturing efforts in the Allgäu region”, says Werner Gut, director of the solar and energy division.
The company supplies various leading storage systems providers with single-phase and three-phase inverters for high and low voltage systems. At its Memmingen location, KATEK not only develops and manufactures OEM components, but also inverters that form part of the “Steca –A KATEK Brand.”
Technology platform enables flexible design
“One of the main driving forces behind the success of our inverters is the central technology platform used in all devices,” explains Werner Gut. This platform’s specific topology enables fully housing-independent cooling and thus particularly flexible product design. In addition, the Steca coolcept technology enables inverters to consistently yield highest peak efficiencies over the entire temperature range.
An additional advantage is the use of common, tried-and-tested assemblies for different inverters. This makes for a particularly advantageous price-performance ratio for users, as production and quality control can be optimised specifically for these assemblies. Whenever there are enhancements to one assembly, all devices benefit from these improvements. The platform design also allows for new functionality to be added particularly easily when needed.
New products planned for this year
KATEK launched a new development department for hybrid inverters back in January of this year. The team’s development efforts include energy management functionality, high voltage battery storage solutions and next-generation technology for residential buildings. “Our new development team will launch additional new solutions and products this year and help us strengthen our leadership position,” adds Werner Gut.

Patented new DHYBRID technology lowers costs and increases the proportion of solar power in microgrids
PRESS RELEASE
Patented new DHYBRID technology lowers costs and increases the proportion of solar power in microgrids
Dynamic inverter control system ensures higher yields and compensates for inverter failures
Munich/Germany, 26 November 2020: The microgrid specialists at DHYBRID have introduced a new technology that lowers energy costs for stand-alone grids by achieving significantly greater solar yields. Simply by improving system management, the recently patented inverter control system can increase the proportion of solar power by more than 10%, with corresponding reductions in the amount of power required from diesel generators or other connected power grids. The Maximum Inverter Power Tracking (MIPT) system achieves these results by continuously adjusting the output of individual inverters or groups of inverters in accordance with the needs of the microgrid.
An infographic is available here: https://www.dhybrid.de/en/press-article/patented-new-dhybrid-technology-lowers-costs-and-increases-the-proportion-of-solar-power-in-microgrids
Higher yields from new and existing systems
Conventional microgrid control systems treat all inverters the same, assigning them an identical maximum feed-in rate – which could be a fixed percentage of their nominal capacity. This means that within a microgrid, PV systems that are producing high yields at any given time are treated the same as those that are not performing as well. The resulting power output losses are entirely avoidable and can have significant effects for microgrids in particular. Microgrids often comprise several PV systems that are all connected but may experience different degrees of shading, for instance.
The MIPT system ensures optimal control by continuously monitoring the outputs of the various PV systems, thereby allowing the maximum feed-in capacity to be dynamically distributed across all connected inverters several times per second. Systems that are running better can feed in more energy, making it possible to take full advantage of the photovoltaic output.
“A similar approach has been used to optimize performance between the PV module and inverter. Our technology takes this to the next level and optimizes the performance of individual inverters within a hybrid system. This allows us to significantly improve efficiency and increase potential savings,” explains Tobias Reiner, CTO at DHYBRID.
“In some cases, we have been able to increase the proportion of PV in our systems by more than 10%,” Reiner adds. To save costs, the new technology relies solely on the MIPT algorithm in the DHYBRID software. Since neither special inverters nor other energy producers are needed, the innovative solution can be used to optimize both new and existing systems.
A positive side effect of employing the dynamic inverter control system is that the output of connected diesel generators does not need to be adjusted as often. When generators run steadily, their efficiency and service lives improve, an effect that is clearly evident in the substantially smoother feed-in curves.
Especially beneficial when inverters fail
The operating principle and the advantages of the new control system become even clearer when an inverter fails. Conventional approaches would treat the defective inverter as if it were still functional, even though it can no longer deliver any yields. By contrast, the MIPT system assigns the remaining systems a higher maximum output power so that they automatically compensate for part of the shortfall.

Visionary electricity supply for traffic management center and highway maintenance depot
Press Release
Visionary electricity supply for traffic management center and highway maintenance depot
ASFINAG, DHYBRID and K.E.M. MONTAGE implement renewable, fail-safe microgrid
Munich/Klagenfurt, 10 March 2021 – The Austrian highway financing corporation ASFINAG has joined forces with its long-time service partner and general contractor K.E.M. MONTAGE as well as DHYBRID, the German microgrid specialists to create a visionary, future-oriented electricity supply for one of the most important traffic management centers and highway maintenance depots in Austria. To achieve this, the organizations have constructed a “hybrid microgrid” at the Klagenfurt highway maintenance depot. This microgrid supplies uninterrupted renewable energy to the entire site, even when the public grid experiences power outages. The Klagenfurt highway maintenance depot’s responsibilities include the monitoring and maintenance of various tunnels through the Alps as well as the well-traveled Tauern Autobahn highway.
You can find press images here: https://www.dhybrid.de/en/press-article/visionary-electricity-supply-for-traffic-management-center-and-highway-maintenance-depot
The project’s role in the ASFINAG sustainability strategy
The highway maintenance depot in Klagenfurt is supplied with solar energy as part of ASFINAG’s plan to gradually switch all company’s locations over to green power. The integrated energy storage system ensures that solar energy generated by day can also be used at night or in the event of grid failure. Until now, such an uninterrupted power supply involved considerable additional technical overheads. Yet this power supply is responsible for making sure that tunnels and sections of highway can continue to be monitored even if the public power grid fails.
“The Klagenfurt highway maintenance depot’s microgrid goes to show that renewable energy and a reliable energy supply go hand in hand, assuming the right technological steps are taken. Thus, the new energy system is more than just a flagship project – it is a real bonus in terms of driver safety,” says Christoph Lang, Head of the Renewable Energy & E-Mobility Department at K.E.M. MONTAGE, the general contractor for the construction of the new power system.
Secure energy supply with the hybrid microgrid
Hybrid microgrids refer to small-scale, local power grids which are connected to the public electric grid. If necessary, they also function in island operation, being independent of the public grid, typically with the help of a battery storage system and specialized electronics.
The Klagenfurt highway maintenance depot’s hybrid microgrid combines a 220-kWp photovoltaic installation with a 522-kWh lithium-ion storage system. The Universal Power Platform (UPP) energy management system from DHYBRID controls and monitors all of the energy supply parameters. If the public grid fails, the battery storage system will seamlessly take over the supply to the microgrid with the support of the UPP.
Once the public grid is back in operation, the UPP measures the necessary parameters and ensures that the microgrid is seamlessly resynchronized to the grid for parallel generation. Under battery operation, the UPP also regulates the load management for three connected charging stations with up to 70 kW for electric vehicles belonging to ASFINAG. If the energy storage system’s capacity is completely exhausted due to a lasting power outage, the UPP will switch on a back-up diesel generator fully automatically.
About DHYBRID
DHYBRID originally developed its microgrid technology for use outside of Europe, for instance in remote areas which cannot reliably be supplied by a stable electricity connection. But the expansion of renewable energy and the increasing demand for customized energy storage solutions have paved the way for increased use of DHYBRID microgrids in Europe as well.

DHYBRID implements fail-safe grid concept for Sri Lanka’s leading utility company
PRESS RELEASE
DHYBRID implements fail-safe grid concept for Sri Lanka’s leading utility company
NETWORKED MICROGRIDS ENSURE THAT RENEWABLE ENERGY IS AVAILABLE AREA-WIDE
Munich/Germany, Colombo/Sri Lanka, 22 October 2020: The off-grid experts at DHYBRID have taken a pioneering approach to the power grid in Sri Lanka. Their pilot project connects stand-alone grids to ensure a fail-safe supply of renewable power that can be utilized throughout the distribution area and expanded at any time. In the first stage of the project, DHYBRID is collaborating with its local partner DIMO to establish a grid-connected microgrid. The client is Sri Lanka’s leading utility company, Lanka Electricity Company (LECO), with power being supplied to the campus of the University of Moratuwa, Sri Lanka’s renowned technical university.
You can find press images here: https://www.dhybrid.de/en/press-article/dhybrid-implements-fail-safe-grid-concept-for-sri-lankas-leading-utility-company
The hybrid microgrid relies on DHYBRID’s Universal Power Platform energy management system as well as the company’s battery energy storage system, which offers 400 kWh of capacity and an output of 400 kW. Power is generated by four roof-mounted solar systems with a combined output of 350 kWp. A diesel generator is reserved for exceptional circumstances.
Automatic compensation for fluctuations
DHYBRID’s hardware and software solution controls all local power generators, manages key electrical loads and avoids disruptions to the grid. Together with the storage system, it automatically compensates for fluctuations in renewable power generation, thereby increasing the autonomy of the local microgrid. Since a significant proportion of locally generated renewable energy is consumed on-site, only minimal amounts of electricity must be drawn from the national power grid. This approach also relieves strain on the public grid by using load management to ensure a more constant feed-in of surplus renewable energy.
Network of grid-connected microgrids provides security
In order to implement the microgrid concept across a broader area, additional grid-connected microgrids are planned. Connecting these microgrids to both the public grid and one another will create a supply system that maximizes local energy use while also preventing area-wide power failures.
The innovative concept of connected microgrids offers several advantages over a power system that lacks access to independent sub-grids: “For one thing, it is easier to coordinate consumers and producers of renewable energy in small-scale, local grids than in a centralized system,” explains Fabian Baretzky, regional manager at DHYBRID. “For another, if there is a power outage, the individual microgrids disconnect from the public grid to provide uninterrupted on-site power. This offers operators a high degree of stability and saves them money.”
If the public grid fails, the DHYBRID Universal Power Platform (UPP) automatically opens the mains breaker, which creates a local stand-alone grid managed by the UPP without interrupting the power supply. When the system detects that the public grid is available again, it measures the necessary parameters and resynchronizes the battery inverter, before seamlessly reconnecting the microgrid to the public grid.

Europe’s largest charging park for electric cars opens
Tesvolt supplies 2 MWh storage system for 100-percent green power
Wittenberg/Germany, 8 October 2020 – Europe’s largest charging park for electric vehicles will open on Friday at the Kreuz Hilden junction. The first construction phase of the “Seed & Greet” charging park is complete and 44 charging stations from various operators are ready, including Europe’s fastest charging stations from Tesla and Fastned. All the charging stations are supplied with 100-percent green power from sources including a large photovoltaic installation on the charging park’s carports and the high-performance storage devices from the German manufacturer Tesvolt.

Europe’s largest charging park project, covering 12,000 square metres, is located at the Kreuz Hilden junction between the A3 and A46 motorways in Germany. The first construction phase involved completing half of the planned 114 charging stations. The current 28 fast charging stations from Fastned and Tesla – including 12 superchargers of the latest V3 generation – can be used to charge electric vehicles with charging power of up to 250 kilowatts (kW). The operator of the charging park will also be providing a further four public charging stations with charging power of up to 22 kW and twelve stations for staff and tenants. While waiting for their cars to charge, motorists will now also be able to use the café-bistro with organic bakery that covers 150 square metres.
Potential hurdles due to Renewable Energy Sources Act (EEG) amendment
“I hope the EEG amendment doesn’t disrupt projects like these in the future. Lots of people have approached me about their interest in setting up similar projects. If the EEG amendment places further restrictions on self-consumption, however, any such projects would be stifled,” says Roland Schüren, master organic baker and operator of the charging park. “Not only do Germany and Europe need more e-mobility, they particularly need more e-mobility with electricity from renewable energies.”
Europe’s most innovative charging park
“Seed & Greet is currently not only the largest, but is also the most innovative charging park. A sophisticated energy concept with heat recovery, rainwater and process water harvesting, the organic bakery and the wooden frame construction of the park, the planned vertical farming – all of this goes towards making Seed & Greet a flagship project,” says Simon Schandert, co-founder and CTO of Tesvolt. “We are extremely proud to be part of this project with our storage systems.”
Prizewinning storage technology
The two battery storage system containers from the German manufacturer Tesvolt store electricity from the currently 336 kilowatt-peak (kWp) photovoltaic installation and two small wind turbines in order to shave the expensive peak loads that occur during the charging of electric vehicles. They also, however, store green electricity from the grid when it is particularly cheap and relieve the utility grid when there is more electricity in the grid than is consumed. Gregor Hinz, energy consultant and technical planner for the project, anticipates that the two storage systems will have paid for themselves in just a few years.
“Tesvolt storage systems can be fully charged and discharged rapidly, which is particularly important from a technical perspective for a charging park. In combination with our hourly purchase of energy on the German spot market, this is the perfect symbiosis for optimal management of self-generated energy,” reports Hinz.
Hinz had a shortlist of three commercial storage system manufacturers for the charging park project. Tesvolt made the grade because its TPS flex storage container offers plenty of power in a comparatively small space and it is one of the few containers on the market that meet the operator’s high technical requirements. Developed by Tesvolt’s engineers, its intelligent battery control ensures optimal charging and discharging of cells, along with an impressive expected service life of about 30 years. Tesvolt has already received several awards for its innovative ideas and projects.
Charging park with vertical farming to be completed in 2022
The second construction phase is planned for the end of this year, when all the charging stations will be complete and the solar installation will be expanded to a total power of 700 kWp. The five-storey building complex is scheduled for completion by the end of 2022, offering office space for various tenants alongside the Seed & Greet café-bistro. The vertical greenhouse, covering four storeys and 1,000 square metres, will then be located between the two buildings, housing salad, strawberries and blueberries grown for use at the bakery.

First hydroelectric-solar microgrid in Patagonia
Tesvolt delivers storage system for Patagonia National Park
Chacabuco/Chile, Wittenberg/Germany, 09/09/2020 – A “run-of-the-river” hydroelectric power station, photovoltaic installation, and battery storage system have been combined to provide facilities in the Patagonia National Park with electricity from renewable energy sources. The park is part of one of the most important nature conservation projects in the world. It was established by the founder of North Face, Douglas Tompkins, and his wife Kristine, previously CEO of the outdoor clothing company Patagonia. The aim of their foundation, Tompkins Conservation, is to rewild the region after decades of heavy overgrazing and desertification.

Renewable energy for outstanding nature conservation project
The Patagonia National Park is one of the most important nature conservation projects in the world. It owes its existence to the vision and financial means of Douglas and Kristine Tompkins. The two Americans moved to Chile in the early 1990s to push for the preservation of some of the most impressive wild landscapes in the world. Together, they helped create and extend 15 national parks in Chile and Argentina and eventually worked with both governments to protect over 14 million hectares of land.
The Patagonia National Park is located an enormous distance from the nearest public utility grid. The power requirements of the park’s facilities have to date been provided by diesel generators – an expensive and environmentally damaging solution.
“Combining run-of-the-river hydroelectric power and a photovoltaic installation is technically very demanding,” explains Gonzalo Rodriguez, engineer at the Patagonian installation company SyR Energía who planned and executed the project. To achieve a total output of 115 kilowatts peak (kWp), two hydraulic turbines were combined with a solar system, both with AC coupling. The lithium-ion battery storage units have a capacity of 144 kilowatt hours (kWh).
In winter and spring, the Patagonian rivers are swollen by heavy rainfall and snowmelt from the Andes. The two micro-turbines convert the energy from the water into electricity. In summer, the water level in the rivers drops significantly and the required electricity is then supplied by the photovoltaic installation. Excess electricity is temporarily stored in the battery storage systems from the German manufacturer Tesvolt.
Sustainable tourism in a natural paradise
The Patagonia park encompasses over 300,000 hectares of grassland plateaus, forests, wetlands and alpine regions. As with the majority of the region, intensive livestock farming on sandy, dry ground in the Chacabuco valley has resulted in extensive desertification. Since purchasing the area in 2004, the Tompkins Foundation has been committed to restoring the original grassland and establishing native plant and animal species. The Estancia Valle Chacabuco sustainable hostel, a restaurant, camping sites, hiking trails, and an information centre and museum allow tourists to immerse themselves in nature and take a vacation with minimum environmental impact. Tompkins Conservation donated the park to the Chilean state and today, the park is maintained by the Chilean National Forestry Corporation (CONAF).
“We are very excited about the construction of the most advanced hydroelectric-solar microgrid in Chile which will continue to provide clean power for the park for many years to come. This alternative energy system minimises the park’s CO2 footprint and therefore contributes to the fight against climate change,” says Carolina Morgado, Executive Director of Tompkins Conservation Chile.
Hydroelectric-photovoltaic storage system runs faultlessly
“The park is so remote that it was extremely important to install installation components of high quality that therefore require minimum maintenance,” explains Rodriguez. “We therefore decided to install storage systems from Tesvolt who lead the field in terms of quality. This has paid off. The installation has now been running without no problems at all for exactly one year.”
Tesvolt specialises in battery storage system solutions for trade and industry. Thanks to the company’s own intelligent battery control, Tesvolt storage systems operate with outstanding efficiency and have a long expected lifespan of 30 years. They are also exceptionally safe thanks to system control down to the cell level.

ENERGY STORAGE EUROPE: Trade fair and conferences showcase new thermal storage technology
Düsseldorf, 12 August 2020. Innovative materials and components for latent and chemical storage systems are creating new momentum in the field of thermal storage. These new types of technology tap into fields of application that have, as yet, been little explored. The high-temperature sector, which is especially important for industrial applications, is one of these.

Innovations in thermal storage technology take centre stage at the ENERGY STORAGE EUROPE conferences and the IRES sessions with top-class participants that will take place in Düsseldorf from 16–18 March 2021. At the accompanying trade fair, which is held in parallel, established companies and international technology start-ups will exhibit their solutions and products in a special area created specially in order to respond to demand. ENERGY STORAGE EUROPE offers users a comprehensive overview of the latest storage solutions that are making production processes more efficient.
“There are a range of remarkable innovations in technology for thermal energy storage. For example, using vacuum super insulation technology enables thickness to be reduced by over 90 percent at temperatures above 300°C. This innovation boost also stimulates the market: In the past two years alone, the number of thermal storage companies in the Federal Association for Energy Storage Units (Bundesverband Energiespeicher, BVES) has doubled,” says Dr Andreas Hauer, Head of the Energy Storage Division at the Bavarian Centre for Applied Energy Research (Bayerisches Zentrum für Angewandte Energieforschung e.V., ZAE).
New materials and chemical reactions
Current fields of research and development also include new composite and sorption materials such as metal-organic frameworks as well as chemical reactions such as magnesium oxide/water or strontium bromide/water reactions at temperatures between 200 and 400°C and 30 to 90°C. These are investigated with respect to their workability and new suitable applications for them.
In the phase change material sector, R&D activity is focusing on new categories such as sugar alcohols, polymers and fatty acids in addition to paraffins and salt hydrates in order to cover application-oriented temperature ranges.
Latent thermal storage methods such as these can also help to optimise electricity storage: In a lithium-ion storage container, they prevent premature ageing processes caused by the battery overheating. Here, the melting temperature of the storage material dictates the temperature inside the container. In cooperation with the Bavarian Centre for Applied Energy Research, the Technical University of Munich has launched a project which is already implementing this technology.
New component designs
New areas of application such as industrial waste heat recovery or flexible sector coupling require new temperature ranges in order to operate thermal energy storage solutions. For instance, the use of renewable electricity offers the option of generating and storing very high temperatures, right up to 1000°C. This requires new storage materials and components as the usual solutions are not suitable for these high temperature ranges. In this context, power-to-heat-to-power systems, also known as Carnot batteries, are proving to be an additional application for thermal energy storage units.
From an industrial perspective, high-temperature thermal storage units can be used in foundries to improve energy efficiency. For example, in an ongoing project, the waste heat from a cupola is stored at temperatures above 200°C. It is subsequently used for the drying and preheating processes, which take place when the cupola is not in operation. Low-cost rock and thermal oil are used as storage media, and the latter also functions as a convector fluid that transports heat from the furnace to the storage unit.
