Our story

From the first sketch to a decentralized H₂ solution in real operation

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.

12.2020
Founding of GHT

Harald Mayer founds Green Hydrogen Technology.

01.2021
Patent application + basic design of the pilot plant

The innovative airflow reactor is patented and the basic design of the GHT pilot plant is created.

03.2022
Patent publication

The patent for the innovative technology for producing hydrogen from waste materials is published.

05.2022
Start of construction of the pilot plant
10.2022
Certification of the feasibility study

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

11.2022
Start-up of the pilot plant

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

09.2024
Partnership with RheinEnergie, hylane (DEVK) and ETG with BMWK

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.”

12.2024
Topping-out ceremony for GHT's first plant in Baden-Württemberg

With the topping-out ceremony for our first plant, we have made the future tangible. An idea gave rise to a real location where waste is already being converted into green hydrogen today.
