The construction of the last unit for the pilot demonstration (Ex-situ Syngas Biological methanation, ESB) has now begun at the innovation workshop at RISE in Uppsala, Sweden. It is the hydrogen supply system that will produce hydrogen on-site by splitting water with energy from renewable electricity. The electrolyzer is of the AEM (Anion Exchange Membrane) type. Through a modular system, it has been designed to be able to produce exactly the amount of hydrogen required by the methanation process, regardless of syngas load.
The goal of the demonstration is to achieve methane production of gas grid quality through methanation of biosyngas without traditional upgrading. Key for success will be to dose just the right amount of hydrogen needed to convert all the carbon in the syngas into methane, but without large surpluses of hydrogen in the product gas. The hydrogen system will thus be the crowning glory in achieving the demonstration goals.
The construction is expected to be completed this spring.

Behind the wall, at the back, is a separate space for storing hydrogen gas cylinders. Right now, the electrolyser modules are being assembled in the floor stands and the next step will be to connect electricity and water.
