Compact Syngas Solutions (CSS) and Carnot are collaborating to power a 40-day sea trial of a zero-emission marine hydrogen engine using 200kg of hydrogen produced from waste. The 50kW hydrogen auxiliary engine, developed by Carnot and funded by a UK government grant, will be tested at Brunel University before being installed on a Carisbrooke Shipping vessel for a trial through the Irish Sea. The global shipping industry, responsible for 3% of greenhouse gas emissions, is mandated to reduce emissions by 40% by 2030 and achieve net zero targets by 2050. CSS, based in Wales, specializes in waste-to-hydrogen plants and secured government funding to enhance its processes, including carbon capture to make the plants more environmentally friendly. CSS's advanced gasification process not only produces hydrogen but also generates electricity, heat, and biochar from waste products. Executives from both companies see hydrogen and methanol as viable solutions for decarbonizing the marine industry. The collaboration aims to demonstrate the potential of waste-to-hydrogen technology in significantly reducing emissions in the shipping sector.
