Flywheel energy storage systems 12.4.2017

New design reduces system costs

Flywheel energy storage systems can play an important role in stabilising the electricity grid. When required, they provide high outputs within milliseconds. The short-term electricity storage systems also act as active voltage filters for optimising the electricity quality. In the KoREV-SMS project, scientists are developing a flywheel energy storage system with an external rotor design. This results in a higher energy density with lower acquisition costs compared to conventional flywheel energy storage systems. .

Energy storage flywheels 12.4.2017

Faster power storage with high cycle rate

Energy storage flywheels as short-term intermediate storage for regenerative energy generation systems can help keep the power grid stable. With good efficiency, they absorb or emit high power levels – while at the same time having an extremely durable cycle. In the ENERSPHERE project, scientists are working on a flywheel rotor with a superconducting bearing. This makes it extremely intrinsically safe and robust. .

Phase-change material (PCM) 11.4.2017

Increase dynamism with three-dimensional wire mesh

To equip modular storage units for a temperature range of 150 to 350 degrees Celsius and achieve high energy and power densities at the same time, is the declared aim of the researchers in the MOSPEDRA-project. The scientists first need to increase the dynamics of the memory modules. They want to achieve with a new metallic thermal wire mesh, which is embedded in a phase-change material. ... more

Sea water electrolysis 10.4.2017

Hydrogen from the sea

Scientists of Berlins Technische Universität Berlin and Freie Universität explore catalytic systems for hydrogen electrolysis directly from seawater. The non-precious metal catalysts should be inexpensive to produce. They make it possible to store renewable energy as hydrogen even at sites with water shortage. This option could be used for offshore wind farms or solar thermal power plants. ... more

Synthesis 3.4.2017

Synthesising methane cost-effectively

In the Katmethan project scientists want to find new peptide-based catalysts for low-cost synthesis of methane. The chances of success are uncertain due to lack of data. The efficiency depends primarily on the achievable efficiency of the catalytic reaction, the catalyst cost per unit and the stability of the catalysts. ... more

Materials and components 15.3.2017

Increasing the energy density of thermal storages

Scientists optimise materials and components for soprtion-based thermal energy storages of high energy density. Sorption reservoirs for buildings currently achieve an energy density of about 130 kWh / m³. In the project MAKSORE the researchers want to achieve an effective usable volumetric energy density of at least 180 kWh / m³. ... more

Hydrogen electrolysis 3.3.2017

Green H2: Producing low cost and load-flexible hydrogen

Innovative electrodes improve hydrogen electrolysis for a wide output range. With their laser-etched surface structures, they are durable and have lower losses at different loads. As a result, the electrodes are particularly good at using the fluctuating supply of excess wind electricity. If upscaled, the structured electrodes can also be used in industrial applications. ... more

Latent heat storage 18.1.2017

Increasing efficiency of power plants and electric arc steelworks

How can energy efficiency in industry and thermal power

plants be increased by using thermal energy storages? Researchers are studying

the integration of thermal storage in different industrial and CHP processes.

The focus is on high temperature storages with a storage temperature above 200

°C. A highlight of the project TESIN is the development, design, build,

commissioning and operation of a latent heat storage unit in the operating CHP

plant in Wellesweiler, Saarland of STEAG New Energies. ... more

Stationary battery storage systems 8.11.2016

Cost-effective manufacture of lithium batteries

Compared with other electrochemical storage systems, lithium-ion batteries have high energy efficiencies, high energy densities and long service lives. They are therefore the first choice for many mobile applications. However, they are still not used very much as stationary storage systems and are comparatively expensive. It is intended that environmentally friendly and cost-effective production processes for the battery cells and storage systems shall change that. ... more

Composite Material 18.10.2016

Increasing the storage density with salt hydrates

How can solar energy be stored better? For optimisation purposes, scientists in the ThessaPor project are developing composite materials that store solar energy thermochemically. The composites are structured so that an inorganic salt is stored in them. This makes it possible to combine the advantages of water vapour sorption storage systems with the advantages of storage systems based on the reversible hydration of salts. ... more
