This will be one of the first cases where green hydrogen is used to lessen the carbon footprint of an existing gas fueled Wärtsilä power plant. The Wärtsilä engine at the site is already capable of operating on gas with up to 3% hydrogen. In order to reach the targeted level of 10% blending to meet the specific needs for Capwatt, modifications will be made to the engine, as well as…
