Energy Efficient Production of Pressurized Hydrogen

The project goal is to test solid oxide cells and stacks at elevated pressure. If the cells can be used for hydrogen production at pressures between 10 and 30 bars, it is expected to result in a significant reduction in the hydrogen production cost since electricity consumption and investment costs for pressurization pumps can be minimized.

The project is organized in four work packages (WPs): In WP1 a single cell test setup will be expanded and improved such that single cells can be tested at pressures up to 30 bar. In WP2 a 1 kW SOEC stack is manufactured. An existing stack test setup will be expanded and improved in WP3 in order to test the stack at pressures up to 30 bar. Finally, in WP4 the commercial aspect of hydrogen production using pressurized solid oxide cells is assessed.

The test results will be used to identify key effects that elevated pressure operation has on SOEC performance and durability in order to be able to optimize cells and stacks for high pressure operation. The commercial exploitation of the project results will be carried out by the project partner Haldor Topsoe A/S.
