The StepCO2 project aims to develop the Ricardo CryoPower technology, a recuperated, split-cycle engine that potentially offers a 30% reduction in fuel use and direct greenhouse gases, and zero-impact exhaust emissions. The technology uses liquid nitrogen (LiN) as an in-cylinder cooling medium or “secondary fuel”, but this LiN is already made using wrong-time renewables, and its low cost means that there is a 20% net fuel saving. The technology targets heavy duty, long-haul trucks, distributed power gen-sets, marine and locomotive sectors.
