Thomassen Energy will use its HyFlex LEC-III combustion system to retrofit one of the gas turbines at Uniper's Rotterdam Capelle (RoCa) power plant. The RoCa power plant is located in the Dutch province of South Holland and has a net power generation capacity of 264 MW. In 2023, Uniper plans to switch the RoCa plant's fuel source from Groningen natural gas to high-calorie gas supply. Thomassen's H2fuel-flex retrofit solution has been successfully operating on three Frame 9E turbines at another customer site in the Netherlands since 2018.
