The Dearman Engine – a zero emission engine which runs on liquid air – took a step closer towards commercial realisation when Ricardo and a team of UK academics stated that the proposal could be completed within two years.

Along with validating the work to date, the engineering team from Ricardo is confident that, given its projected performance, there are numerous practical applications for the use of Dearman Engine in the future marketplace: “The technology could compete with hydrogen fuel cell and battery electric systems in zero emission applications.”

Ricardo has confirmed two key benefits - low cost and simplicity, and believe that these could aid the success of this technology: “In the longer term, the technology could also be suitable for small vehicles operating in urban environments.”

We look forward to working with DEC in the coming months to help bring its technology closer towards commercial maturity.

Toby Peters, Founder of Dearman Engine Company explains, “This is a rigorous independent technology review and engine feasibility study by a highly respected global engineering consultancy. Clearly we still have a long way to go to build a fully optimised demonstration engine and also get people to believe that using cold air as an energy vector is not a load of hot air. Ricardo’s thumbs-up gives us real confidence that we have something exciting.”

With due diligence concluded, the Dearman Engine Company and Ricardo are starting work on the development of the demonstration engine. Ricardo believes that the company should have a fully characterised demonstration engine inside two years.

Nick Owen, Project Director for research and collaboration at Ricardo UK, commented, “We look forward to working with DEC in the coming months to help bring its technology closer towards commercial maturity.”

Working alongside Ricardo, DEC enjoys the active support of a team of University research experts from Loughborough, Brighton, Leeds and Queen Mary Universities and STFC. This team meets regularly to support the work of Ricardo and specifically bring specific expertise around different aspects of this very novel engine technology.

DEC has confirmed that with this key technical verification, it is planning a formal fundraising early this year to support full commercial development.
