The first green hydrogen has been produced and bottled in trailers by Hy2B Wasserstoff GmbH from its plant in Pfeffenhausen, the Hy2B reported.
The Hy2B hydrogen generation plant will initially produce 440 tonnes of green hydrogen per year; the expansion of the plant to 10 MW should then enable more than 900 tonnes of green hydrogen to be produced in the coming years.
Green hydrogen in Pfeffenhausen is produced by alkaline electrolysis from Nel Hydrogen at atmospheric pressure, with a high level of safety without pressurised equipment in the electrolyser area, low requirements for process water quality and water treatment, as well as proven durability and robustness.
The two-stage hydrogen compression is performed by two industrial compressors from Howden, A Chart Industries Company: a six-stage piston compressor, which compresses the hydrogen to up to 200 bar, and a diaphragm compressor, which compresses the hydrogen to a filling pressure of up to 380 bar.
The final drying and deoxidation is carried out after the first pressurisation stage; measurements show a purity of 5.0 in accordance with DIN EN 17124.
Three filling stations with 380 bar filling pressure allow the use of state-of-the-art trailers with more than one tonne of storage capacity Hy2B Wasserstoff GmbH currently has 4 trailers, each with a storage capacity of 1.25 tonnes. This number is set to grow to 6 trailers in 2025.
Hydrogen can be supplied in purity levels 3.7 to 5.0. As soon as certification for RFNBO (Renewable Fuels of Non-Biological Origin) according to REDII regulation is possible, Hy2B will offer green hydrogen in RFNBO quality.
