Demonstrasjon og kvalifisering av lettvekts OTSG for offshore Combined Cycle Power Plants

Offentlig prosjektsammendrag

Techouse AS, together with SINTEF and leading energy companies, will develop and qualify a new lightweight Compact Once Through Steam Generator (COTSG) for offshore combined cycle power plants. Current steam generators are too heavy and bulky for most offshore platforms, which limits the adoption of this highly efficient and environmentally beneficial technology. The project will design, manufacture, and test a full-scale COTSG prototype at Sustainable Energy’s facility in Stord, Norway. The goal is to achieve 40–50 % weight reduction and 10–15 % smaller footprint, while maintaining high thermal efficiency and operational reliability. By combining advanced modelling, new materials, and full-scale pilot testing, the project will create new knowledge and deliver a validated solution that can reduce CO₂ emissions from offshore gas turbines by 22–25 %.
