World's first industrial power-to-gas plant

In the WOMBAT project, researchers are pursuing the idea of combining the electricity and gas network. The intention is to utilise surplus electricity from renewable sources for generating hydrogen. This is synthesised with carbon dioxide in biogas plants to form methane, which is the main component of natural gas. This makes it possible to utilise the complex infrastructure for the gas industry, ranging from the transport to the storage. ... more

Lithium combustion 30.9.2015

Lithium, the renewable coal

Lithium can be used for chemically storing electricity as part of a cycle in which it is first generated electrochemically using surplus electricity and then combusted as required in a power plant-compatible process to release the energy again. In the “LiKohle” project, researchers are investigating and assessing the possible reaction processes, for example in a carbon dioxide or nitrogen atmosphere. Valuable chemical raw materials can be generated as a by-product of the energy conversion. ... more

Solar hydrogen production 3.10.2016

Direct conversion of solarenergy in hydrogen

So far, in solar hydrogen generation PV modules are coupled via a dc interface with a central electrolysis unit. The aim of the joint project "HyCon" was therefore a radical simplification of the system by using novel integrated approach. To this end, in a concentrator High Efficient III- V multijunction solar cells are connected directly to an electrolysis cell. In tis way, still unmatched conversion efficiencies of sunlight into hydrogen more than 20 percent can be achieved. ... 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

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

Latent heat storage 1.10.2015

Waste heat used for production of precast concrete

Researchers develop new components in the project ENBELAT. To use the hydration heat they provide concrete precast molds with a heat recovery and save the heat in a latent heat storage. This increases the quality and helps the energy consumption to be reduced 45 percent. ... more

PCM storage 12.4.2017

Cheaper slurries for cooling processes

In order to reduce the cost of PCM storages, scientists develop new slurries and materials for cold storages. The aim of the project KOLAN is to develop an emulsion with a very high heat capacity. At a temperature difference of 6 Kelvin it should store about four times more heat than water. ... more

Latent heat storage 2.2.2016

New economical phase change material

Scientists at the University of Bayreuth are optimizing mobile latent heat storages. In the project MALATrans they improve charging and discharging capacity of the heat storages and analyse how the manufacturing costs can be reduced. The phase change materials they are working with are macroencapsulated. ... more
