Frequently asked questions

What is special about GHT's technology?

Green Hydrogen Technology's production process produces hydrogen from non-recyclable waste and takes regional site conditions into account. GHT technology is based on a new, patented process. In this process, plastic or biomass waste is converted into synthesis gas by gasifying it in a hot gas. The hot gas is produced when the process's own synthesis gas, biomass or decoupled process heat is burned.

The production plant can thus be adapted to the operator's available resources. With its decentralized orientation, the technology requires no complex infrastructure and avoids high transport costs.

What exactly distinguishes GHT technology from hydrogen production through electrolysis?

Water electrolysis breaks down water into hydrogen and oxygen. This requires enormous amounts of valuable green electricity. As a result, the price of green hydrogen from electrolysis is very expensive. In GHT technology, the hydrogen and the energy to separate the hydrogen come from the raw material itself, which allows the price to compete with that of conventional fuels. The CO2 is separated and liquefied, making the GHT process as climate-neutral as water electrolysis.

How does GHT technology differ from other types of carburettors?

GHT has developed a superior process to produce climate-friendly hydrogen. The advantages over other thermal-chemical processes are clear:
- High temperature leads to complete decomposition of the raw materials and thus to the highest possible hydrogen yield
- Toxic substances such as dioxins and furans are not produced and PCBs are completely decomposed
- Avoiding tar and soot (which is often problematic at lower gasification temperatures)
- Lower production costs (due to negative-priced raw materials)
- Reasonable use of waste that is available in large quantities

What type of plastic does GHT use?

GHT utilizes non-recyclable plastic, which is otherwise exported and landfilled, entered into the environment in an uncontrolled manner or incinerated, releasing significant amounts of CO₂. Among other things, substitute fuels (EBS), which are used today in the cement industry, and production waste, which is currently being thermally treated in waste incineration plants, can be used.

Where do the raw materials for operating a GHT plant come from?

Green Hydrogen Technology's production process is based on climate-friendly hydrogen production from plastic waste, wood waste and other biogenic residues.

‍Plastic waste
‍There is no useful use for plastic waste that cannot be recycled. In Germany, that is annual 5.9 million tons. More than 60% of the waste generated is thermally recycled, mainly in waste incineration plants and in the form of substitute fuels in the cement industry. (Source: Federal Environment Agency, 2023)

Wood waste
‍Despite sophisticated recycling systems, a large proportion of wood waste cannot be recycled. In Germany, that is per year 11 million tons (Source: Technology for Wood and Natural Fiber-Based Materials).

What products and residues are produced when the plastic is converted in the GHT plant?

Hydrogen and CO are mainly produced₂. The inorganic constituents produce ash with the main constituents CaO, SiO, TiO₂ and Al₂O₃. The ash is filtered out and can be processed for further use.

Why is the process more environmentally friendly than other recycling methods?

Traditional thermal recycling of plastics in waste incineration plants produces enormous amounts of CO₂ emitted into the atmosphere. Because in the process of Green Hydrogen Technology CO₂ If present as a liquid product, these emissions can be eliminated. CO₂ There are already various technical applications available today or can be stored as an alternative.

Why can a GHT plant produce hydrogen cheaply?

GHT uses waste (plastic waste, biomass) as Raw materials that are available free of charge or even have a negative price have. In addition, it limits Decentralized orientation of the plants the transport costs of the H₂ to a minimum. It can be produced where H₂ is needed.

How much hydrogen can a GHT plant produce per year?

The patented technology is exceptionally efficient and scalable. GHT systems produce up to 4,000 tons climate-neutral hydrogen.

Where is a typical GHT plant located?

Chemical and industrial parks: large industrial associations with various production sites. Green Hydrogen Technology consumes waste generated there and produces CO₂ and H₂ as a raw material and energy source for local industries.
‍
Disposer: With GHT technology, waste management and recycling companies can recycle their waste streams in a climate-neutral way, convert them into valuable energy and thus expand their portfolio. Non-recyclable fractions serve as a raw material source for the production of hydrogen and CO₂. Waste thus becomes an energy source that can be used locally or fed into the energy system.

Energy producers: Expanding the portfolio to include hydrogen. These customers benefit from their wide network of potential customers₂-Customers.

Manufacturing companies: In manufacturing companies where plastic waste is produced as a by-product, for example in the packaging, automotive or consumer goods industries, GHT technology can be used directly on site. Production waste, batches or scrap materials are converted into valuable raw materials and serve as a basis for producing green hydrogen. Companies are thus reducing their disposal costs, avoiding CO₂ emissions and creating a closed material cycle.

What are the next steps?

The existing design of the demonstration plant in Ebersbach an der Fils is being scaled up to industrial scale. In the second step, the findings of the first industrial plant are used to develop a standardized and modularized plant that can be put into operation reliably in a short period of time. At the same time, the technology is being further developed for the use of other input materials.

Is the technology already ready for use?

We are on our way to industrial production. All steps of the production process have been tested on an industrial scale or are state of the art. The first demonstration plant has been in operation since April 2025 and continuously produces synthesis gas from wood dust and, as a test, from plastic waste.

Are there also other ways to use the resulting synthesis gas?

Yes, other products can also be produced from synthesis gas using proven technologies - for example methane, methanol, SAF (Sustainable Aviation Fuels), electricity or the synthesis gas is used to produce basic chemical substances such as glycol, ethanol or acetic acid.
