The world’s first liquid air engine will take a big step closer to reality this summer when U.K.-based Dearman Engine Company begins full-on vehicle testing of its Dearman heat engine. The nitrogen-fueled engine is designed to propel refrigerated trucks, providing an emission-free and fuel efficient ride. The engine could go into production in two years, saving U.K. heavy-duty vehicles 1.3 billion liters of diesel consumption and reducing carbon emissions by more than a million tons by 2025 while dramatically reducing air pollution.

The engine was developed by Dearman in partnership with U.K. engineering consultancy Ricardo and the universities of Leeds, Birmingham, Loughborough and Brighton. The testing program will be carried out in partnership with MIRA (Motor Industry Research Association)Air Products and Loughborough University, and it is being partially funded by the U.K. government.

“MIRA is proud to lead a project delivering the world’s first demonstration of a liquid air engine in a commercial vehicle. Liquid air is an exciting new energy vector and has the potential to make a major contribute to the low carbon challenge facing the transport sector,” said Chris Reeves, commercial manager for future transport technologies and intelligent mobility at MIRA.

The U.K. is already is home to a network of industrial gas plants producing liquid nitrogen so the existing infrastructure will allow for fast deployment.
