A hydrogen electricity power plant combines the coal gasification and combined cycle power plant technology. Both technologies are well established and proven. A gasification plant converts solid fuels, like coal and clean, sustainable biomass into syngas, which is a mixture of mainly hydrogen and CO. The CO can be converted in CO2 which can then be separated and stored safely in order to avoid contribution to the global warming. The hydrogen is transformed into electricity in a combined cycle power plant. The hydrogen can also be supplied for industrial use (H2-hub).
The main difference with conventional solid fuel power plants is that the major portion of the CO2 is captured for storage and not released into the air. Hydrogen electricity plants also have high fuel flexibility. The main fuel is coal, but petcoke and biomass may also be gasified.
C.GEN will build its first hydrogen plant in the Port of Rotterdam. The plant will have an overall net electricity generating capacity of 400-450 MWe and the ability to separate and prepare the CO2 for transport and storage from the start of its commercial operation. This means that the plant will be a full carbon capture plant. This is a main difference with the so-called ‘carbon capture ready’ projects, where the intention is to build a conventional solid fuel power plant that will allow future investments to capture the CO2, but starts commercial operation mainly as a conventional solid fuel power plant.
Some general points regarding the hydrogen electricity power stations of CGEN:
• Projects will be designed in modules which will be similar to the Rotterdam project;
• Each module, with a net generating capacity of 400 - 450 MWe, will consist of one air separation plant, gasifier plant, the necessary shift reactors and gas purification equipment, one gas turbine with heat recovery steam generator and one steam turbine;
• Various modules may be built next to each other or possibly interconnected.
