Hydrogen in the tank

In order to achieve climate neutral transportation, different types of fuel such as electricity, biogas and hydrogen are needed.

A VA SYD PROJECT The aim of “Hydrogen in the Tank” was to create a cost-effective and secure value chain for hydrogen production, in order to increase incentives for the use of hydrogen as a fuel within the transport sector. As part of this, synergies between hydrogen production and wastewater treatment were explored through a case study at one of VA SYD’s treatment plants.

In addition to using the by-product oxygen to replace electricity consumption for aeration, hydrogen can be used to methanise carbon dioxide in the biogas produced at the plant. One conclusion from the project was that sector coupling—such as synergies with wastewater treatment plants—can contribute to making it possible to produce green hydrogen in electricity area SE4 at a reasonable cost.
