Augsburg-based Green Hydrogen Technology GmbH believes its plants are close to market maturity. An industrial-scale pilot plant has now gone into operation in Austria.
Annually up to 5,000 tons of hydrogen, produced from sewage sludge, wood and plastic waste: The plants of the Augsburg start-up "Green Hydrogen Technology GmbH" (GHT) should make the regional, climate-friendly, cost-effective and competitive production of green hydrogen possible. The company promises this in a press release on the occasion of the commissioning of a pilot plant in Leoben, about 60 kilometers northwest of Graz (Austria).
The three-phase process developed and patented by GHT does not require the use of fossil fuels at all. In a first phase, hot gas is obtained by burning biogas or sewage sludge, to which plastic or wood waste is then added in the second phase for thermal utilization. In the third phase, the resulting hydrogen is processed into green hydrogen with an efficiency of 99.9 percent. In addition, the phosphorus contained in the sewage sludge is also separated in the course of the process.
GHT puts the production costs for one kilogram of green hydrogen obtained at 2 euros. The start-up says its process is particularly attractive for municipal companies. These could fulfill their waste disposal mandate and at the same time produce green hydrogen without costly infrastructure, for example for CO2-neutral operation of local public transport.
The company is targeting market entry for 2023, according to information on its website. In preparation for a first round of financing, the company is currently in talks with investors, GHT said.
