What began as an idea is now in use: A completed, ongoing pilot project provides reliable data — supported by team building, practical proofs and partnerships with industry and municipalities.

The basic design of the GHT pilot plant is underway.


TÜV Süd has tested the production process for processing hydrogen from wood waste. The process therefore meets the requirements for certification.

The first tests on an industrial scale are being carried out in Leoben (Austria).

With RheinEnergie, hylane and ETG, GHT was able to gain strong partners in a first round of financing. Together, the first plant is being built that converts waste into climate-neutral hydrogen and thus initiates the market entry of “hydrogen made in Germany.”

With the topping-out ceremony of our first facility, we have made the future tangible. What began as an idea has become a real-world site where waste is already being converted into green hydrogen today.

Arboris has joined GHT as a long-term investor, securing the funding for its next phase of growth. With this fresh capital, GHT is accelerating the industrial scaling of its technology for converting non-recyclable waste into climate-neutral hydrogen and implementing further large-scale projects within the waste management sector.
Collaboration, quality and reliability — that's what we stand for every day.
