Dolphin N2

Dolphin N2 have a radical vision to challenge how both freight transport and distributed power generation and storage solutions are developed, by harnessing their CryoPower technology. CryoPower is a recuperated, split cycle thermal engine, which has the potential to reduce fuel use by up to 30%, with a clear pathway to sustainable future fuels. The technology also reduces emissions of NOx and particulates to levels at which their impact is near zero. The use of liquid nitrogen in the thermodynamic cycle, enables Dolphin N2 to make use of a by-product of industrial processes, which is already manufactured using off-peak and wrong-time renewable energy. The technology does not make use of exotic or energy-intense raw materials, found for example in the production of batteries, fuel cells and electric motors. Its manufacture and maintenance is also readily compatible with existing infrastructures and supply chains. It thereby offers an economically attractive and environmentally sustainable route to the long-haul transport and distributed energy needs of the future.
