Providing a low-carbon hydrogen source from sewage sludge.

The current solution proposed by the project, the application of supercritical water gasification (SCWG), is used for residential and industrial (e.g. meat industry, beer industry, canning industry, paper industry, sugar industry, etc.) sewage sludge, as well as other wet biomass (e.g. slaughterhouse waste, offal, wet feathers, spoiled food, excess squeezed beet slices from sugar factories, bottom residues from operating biogas plants, diluted manure from livestock farms, wet organic fractions from municipal waste sorting plants, etc.) into gas with a high hydrogen content, the most efficient energetic and environmental solution, which is available in a spatially distributed manner , a renewable low-carbon hydrogen source, close to potential users. The high hydrogen content of the generator gas coming out of the tube reactor of the SCWG technology can provide a significant amount of continuous low-carbon hydrogen source for cars and buses in cities, as well as for trucks along the main transport corridors.

In the ongoing project, the company is installing a 2.0 MW electrolysis system at the Kardoskút Underground Gas Storage Facility. By operating the electrolyzing equipment to be installed, it can be ensured that instead of “switching off” the renewable energy source, hydrogen is produced through water splitting by using the excess electricity. The hydrogen produced in this way is mixed with natural gas according to the plans and used in the equipment of the Magyar Földgáztórő Zrt. originally operating on natural gas, thereby directly reducing their CO2 emissions.

In addition, with strict adherence to quality standards, natural gas will also be delivered to end consumers through the supply system. The ripple effect of the Akvamarin project is that it directly takes the first step towards the widespread spread of hydrogen technology by using the existing infrastructure.
