Green hydrogen is a building block for the energy transition. For mobility, industry and heating, among other things, the environmentally friendly substance has moved into the focus of the German government and the EU Commission.
In the largest German hydrogen mobility project eFarm, H-Tec Systems shows with its electrolyser how green hydrogen can be produced.
The generation of green hydrogen from wind power in the GP Joule project eFarm also brought Federal Transport Minister Andreas Scheuer and State Energy Transition Minister Jan Philipp Albrecht to the inauguration in Bosbüll, North Frisia. The electrolyser used in the eFarm pilot project is the result of 20 years of research and development by the hydrogen experts at H-Tec Systems, as the company writes in a press release. “The highly flexible H-Tec Systems electrolysers are perfect for the dynamic availability of renewable electricity,” says Ove Petersen, CEO of the GP Joule group and initiator of the eFarm project. The electrolyzer’s container solution is just as impressive as the price-performance ratio, which leads to minimal hydrogen production costs.
95 PERCENT EFFICIENCY
The joint project eFarm will use a total of five electrolysers that can each generate up to 100 kg of hydrogen per day from drinking water and electricity, with a nominal load of 225 kW each. The mobility project eFarm will in future provide hydrogen to local public transport and also to private transport via two filling stations. “The high quality hydrogen produced here is suitable for the operation of fuel cell vehicles without further refinement,” explains Heinrich Gärtner, Managing Director of H-Tec. The waste heat from the electrolysis process is also used. At eFarm, it flows into the regional heat supply for industry and private households. The overall system thus achieves an efficiency of up to 95 percent.
ELECTROLYSER FOR A WIDE RANGE OF APPLICATIONS
“Green hydrogen can be produced by anyone who has renewable energies and around 14 square meters of space for the electrolyzer,” says Heinrich Gärtner. For operators of wind and solar systems without subsidies, sector coupling through hydrogen is a good opportunity to use their systems profitably. The electrolysers used here are turnkey integrated into a 20 or 40 foot container. These compact solutions can be used anywhere – directly on wind and photovoltaic systems, at petrol stations or in industrial companies.
