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

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

Organic PCM 5.9.2016

Phase change material is crystallised

With micro-encapsulated or emulsified organic phase change materials, the solidification temperature is frequently below the melt temperature. This so-called undercooling is a hindrance for many applications. By means of systematic investigations, the researchers achieved a fundamental understanding of the physical principles. Based on the experimental findings, models developed that make it possible to forecast the crystallisation properties. ... more

Double layer capasitors 1.9.2016

Activated carbons increase energy density

Scientists develop new electrode materials for high-efficiency double layer capacitors within the project ActivCaps. In contrast to purely empirical investigations they will characterize the structur of the materials at the nanoscale and will adjust simulation algorithms to the materials. The developed simulation tools can then be used for development of materials. ... more

Latent heat storage with super insulation 1.8.2016

How to store heat for weeks

Scientists are developed solar cylinders, which can store solar heat for weeks. For this purpose they combineed a patented latent heat storage material with super insulation. Compared to equally sized conventional water storages, the solar cylinders have three times the storage capacity and have only one tenth of the heat losses. ... more

Latent heat storage based on salt 18.7.2016

„SALSA“ makes steam and waste heat useable

The Fraunhofer Institute for Solar Energy Systems ISE, Novatec Solar and Köllemann are developed a salt-based latent heat storage called SALSA. This is to used for waste heat recovery in industrial processes. In the end of 2016, the storage was integrated and tested in the southern Spanish power plant PE1. ... more

Liquid sorptionstorage 4.7.2016

Saline stores process and solar heat

Scientists at the University of Applied Sciences Stuttgart constructed an open air run sorption heat storage, that regenerates itself by process heat or solar thermal energy. Prototypes were developed, consisting of regenerator, absorber and the storage. These can be used for various cooling, heating and drying applications. By 2017, the storage is to be ready for the market. ... more
