Green hydrogen

The Plagazi Process for production of hydrogen, out of GROT (wood residues) and other organic waste, is green according to the CertifHy definition and gives a negative CO2 contribution when combined with CCS.

There is a new emphasis on hydrogen in Europe, following the presentation of the European Hydrogen Strategy, and the formation of the Hydrogen Alliance in July 2020.

The Hydrogen strategy has set up ambitious targets for hydrogen production, but still with a bias on electrolysis. The European Commission should welcome all technologies, and reward CO2 reduction. Green Hydrogen, however it is produced.

With a certification of hydrogen, as suggested by CertifHy, the emissions from the life cycle of the production process determines the labelling of the hydrogen. The more efficient the process, the better the raw material, the greener the hydrogen will be.

Plasma gasification for producing pure hydrogen out of renewable feedstock, e.g. woodchips or sewage sludge, or even recycled carbon fuels, would be an important technology. To be able to create hydrogen from renewable and non-recyclable fossil waste is a double benefit for
municipalities and waste handlers.

Comparing to the emission benchmark for low carbon hydrogen set up by CertifHy of < 36,4 g CO2e/MJH2, a plasma gasification with a renewable raw material, say GROT (forest residues) would have an indicative value of 4 g CO2e/MJH2, without CCUS. If all CO2 formed in the process is captured and stored the emissions is negative, -112 g CO2e/MJH2.

Transport & Environment, a prominent green Brussels Think tank, suggested in their comments to the strategy: A robust sustainability framework on renewable hydrogen is needed for their use in transport (and also other sectors). The lack of a clear framework will be a barrier for a nascent hydrogen industry: Stringent rules can help ensure that the hydrogen industry contributes to building new and additional renewable energy.

CCS or CCUS is an important additional technology that will even further add to the benefits of hydrogen from a climate perspective. Development is ongoing, and looks promising.

The Plagazi Process for hydrogen production is a new patented innovation and a pioneering method based on plasma gasification for producing pure hydrogen out of renewable feedstock, e.g. forest residues or sewage sludge. The patent is protecting a combination of three existing processes, plasma gasification, water-gas-shift and cleaning process steps to extract pure and green hydrogen, suitable for fuel-cells and different kind of industrial applications.
