Recently, the tests for injecting hydrogen into the natural gas line of the CHP plant successfully started. The first phase of the pilot project aims to inject up to 20% hydrogen by volume into the natural gas plant. During the trial period, the hydrogen is to be delivered by road. The mixture is delivered to an unloading installation for hydrogen depressurisation, which transfers the hydrogen to a lower pressure. The hydrogen is then injected into the gas turbine gas supply in a controlled manner via a mixer. The first tests, which evaluated the process and equipment, were carried out with ENGIE Laborelec and ran very smoothly. The initial tests to inject up to 10 vol% hydrogen were successful and are currently being analysed with the goal being to increase the percentage of hydrogen.
The ultimate goal (phase two) would be to produce green hydrogen from the surplus electricity that is generated. This on-site, modular hydrogen production, to be implemented in the upcoming second phase, is the result of a collaboration between EQUANS and INEOS Phenol and it is being looked forward to.
