Green Hydrogen Technology

What Green Hydrogen Technology does

Green Hydrogen Technology GmbH (GHT) is a German renewable-energy technology company founded in December 2020 in Augsburg by Harald Mayer. GHT has developed a patented thermochemical conversion platform, branded as the ChemQuench process, in which non-recyclable plastics and wood waste are gasified in a hot gas stream at temperatures up to 1,600°C to produce hydrogen-rich synthesis gas. The synthesis gas is purified via Pressure Swing Adsorption (PSA) into H₂ 5.0 purity hydrogen, with marketable liquid CO₂ and reusable ash (CaO, SiO₂, TiO₂, Al₂O₃) recovered as by-products. The technology is protected by a patent filed in January 2021 and published in March 2022, and was independently validated by TÜV Süd in October 2022.

GHT's commercial offering consists of modular, decentralized hydrogen production plants with a footprint under 500 m², designed for deployment directly at waste-management, industrial-park, or utility sites. The first industrial-scale plant, located in Ebersbach an der Fils (Baden-Württemberg) and operated by partner ETG Entsorgung + Transport, became operational in April 2025 with capacity of up to 100 tonnes H₂/year from approximately 1,200 tonnes of waste input. Full-scale commercial plants are designed to produce up to 2,500 tonnes of hydrogen per year from up to 25,000 tonnes of waste, with a stated production cost of up to €1.50/kg—an 85% cost advantage claim over conventional hydrogen production. The company also offers synthesis-gas utilization solutions for downstream conversion into Sustainable Aviation Fuel (SAF), methane, methanol, electricity, and chemical feedstocks such as glycol, ethanol, and acetic acid.

GHT serves three primary enterprise segments on a horizontal basis: waste management companies seeking value creation from non-recyclable fractions; industrial companies with high energy demand or plastic/biomass by-products; and energy utilities looking to diversify into locally produced green hydrogen. Revenue is generated through a combination of direct plant deployment at partner sites, technology licensing, and contracting arrangements (exemplified by RheinEnergie AG contracting the Ebersbach plant), with hydrogen and CO₂ sold under project-specific multi-year agreements. Go-to-market is enterprise field sales, with CEO Robert Nave (former McKinsey Associate Partner and JP Morgan investment banker, appointed February 2023) personally engaging investors and customers. Strategic partners include ETG Entsorgung + Transport, RheinEnergie AG, hylane (DEVK-Gruppe), Westfalen-Gruppe, and Griesemann Gruppe, with €4 million in co-financing from Region Stuttgart supporting the pilot deployment.

Revenue model

1. Green Hydrogen Sales: GHT generates revenue primarily from selling climate-neutral hydrogen produced at its decentralized plants. Hydrogen is sold to industrial customers, energy utilities, and mobility operators (e.g., hydrogen truck fleets). The company also sells the liquid CO₂ by-product to industrial buyers (e.g., beverage and chemical industries). Ash residue is processed and sold for further industrial use.
2. Plant Licensing and Technology Deployment: GHT deploys its patented technology at partner sites (waste management companies, industrial parks, energy producers). Revenue is generated through plant construction, technology licensing, and operational support arrangements. Contracting models (e.g., RheinEnergie contracting the Ebersbach pilot plant) represent another deployment format.

Core offering

Green Hydrogen Technology (GHT) produces green hydrogen from non-recyclable waste (plastics, wood, MSW fractions) using its patented ChemQuench thermochemical conversion process. The company manufactures and sells modular, decentralized hydrogen production plants that yield high-purity H2 5.0 grade hydrogen alongside marketable by-products such as liquid CO2 and ash, and also offers Synthesis Gas Utilization solutions routing syngas to downstream products such as Sustainable Aviation Fuel, methanol, ammonia, and carbon nanotubes.

Product overview

Green Hydrogen Technology offers a modular, decentralized hydrogen production system consisting of core plants that convert non-recyclable waste into climate-neutral hydrogen. The flagship product is the GHT Hydrogen Production Plant utilizing the patented ChemQuench process and Pressure Swing Adsorption (PSA) purification. The pilot plant in Ebersbach demonstrates the technology at industrial scale, producing hydrogen from plastics and wood waste at up to 1,600°C. The company also provides synthesis gas utilization solutions allowing conversion to SAF, methane, methanol, or electricity. Plants are designed for waste management companies, industrial facilities, and energy producers, with production costs targeting €1.50 per kilogram of hydrogen.

Scale indicators6 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Air Products: US-headquartered industrial gas giant with major green hydrogen project pipeline in Europe. Comparable as a large-scale green H2 supplier competing for the same industrial and mobility offtake as GHT.
• Sunfire: Dresden-based Sunfire is one of Europe's most advanced hydrogen/electrolyzer companies, building large-scale SOEC electrolysers and Power-to-X projects. It is a broader hydrogen competitor in Germany and the most logical alternative for industrial decarbonization buyers.
• Hitachi Zosen Inova: Swiss-Japanese firm operating large-scale waste-to-energy gasification plants globally. It shares GHT's waste-gasification foundation but targets electricity/syngas rather than hydrogen, making it an adjacent incumbent in the waste-gasification engineering space.
• Linde: Global industrial gases major that produces and distributes green hydrogen at scale. Linde is the dominant incumbent GHT must compete with for industrial H2 offtake in Germany and Europe.

Direct peers

• Enerkem: Canada-based Enerkem converts non-recyclable waste into methanol and renewable hydrogen via thermochemical gasification. Like GHT, it monetizes a negative-cost waste feedstock into low-carbon hydrogen/chemicals, making it the closest direct peer in waste-to-hydrogen.
• Mura Technology: UK-based Mura operates hydrothermal plastic-to-chemicals plants that produce circular hydrogen and naphtha from mixed plastic waste. It competes with GHT for the same plastic-waste-to-hydrogen value proposition, particularly in the EU.

Emerging players

• Hydrogenious LOHC Technologies: Erlangen-based hydrogen logistics company using liquid organic hydrogen carriers. Comparable as a German hydrogen scale-up addressing industrial/mobility H2 supply chains, complementing rather than competing head-on with GHT's production technology.
• ITM Power: UK-based PEM electrolyzer manufacturer and project developer building large-scale green hydrogen plants across Europe. A direct competitor for green hydrogen offtake in industrial and mobility markets.
• Nel ASA: Norwegian electrolyzer manufacturer focused on green hydrogen production. Comparable as a hydrogen technology provider pursuing the same industrial decarbonization buyers, but via electrolysis rather than thermochemical conversion.

Regional players

• Westfalen-Gruppe: German family-owned industrial gases and energy services company and GHT's strategic partner. Comparable as a regional industrial-gas supplier/distributor in Germany that increasingly supplies hydrogen to industrial and mobility customers.
