The Centre For Low Carbon Futures has revealed that liquid air could power cars in the future. In simple terms, it is created when excess energy from a renewable source such as a wind turbine is used to cool (say) 700-litres of air to -196C. This reduces its bulk to 1-litre which is then stored in an insulated vessel.

When energy is required, it is heated to boiling point which forces it to expand back to its original proportion (in gas form). This expansion could power a wind turbine that might then produce electricity for the national grid. It could also fuel cars, ships, trains, lorries, motorbikes, etc.

Gasworld - Liquid air - Nitrogen economy or false economy?

As liquid air continues to gather pace and plaudits, gasworld looks at its feasibility, at the heart of which are industrial gases and expertise.

The Dearman Engine Company is in fact currently on track to demonstrate a first engine for waste heat hybrid and combined power and cooling, later this year. This can meet the here-and-now challenges facing niche, but still significant, markets and could therefore be deployed sooner than the next decade, we understand.

Professional Engineering - Solid future for liquid air

With two companies working on liquid air engines, the technology is gearing up to become a viable option in the low-emission vehicle stakes.

So far, the peak pressure achieved inside the Dearman engine test cylinder is 103bar. But the system is constrained by a pressure relief valve. Typically, the peak pressure inside a petrol engine cylinder is around 100bar, while that in a heavy-duty diesel engine is 200-300bar. The rate of pressurisation within the Dearman engine is similar to that of a petrol engine.

Euroasia industry - Cool Runnings

Faced with an uncertain environmental future, industry has to adapt and innovate as its dependence on conventional power supplies and fuelling methods are pushed to the limit. One innovation that could play a crucial role in facilitating decarbonised future is Liquid Air technology - an environmentally friendly “cryo-power” pioneered by British inventor, Peter Dearman. Euroasia Industry’s Leonard Owen speaks to Toby Peters, CEO of the Dearman Engine Company, and Professor Richard Williams, Head of the College of Engineering & Physical Sciences at the University of Birmingham, for their views on how Liquid Air could be developed to meet future power and vehicular needs.

Can excess renewable energy be stored as liquid air and then be transported to the grid? Yes, says British inventor, Peter Dearman, who has invented a new system that can harness and store excess energy, while using low grade waste heat and omitting only cool air.

Dearman’s invention is starting to garner huge attention. Earlier in the year a major new report from business and academic experts stated that Liquid Air is a proven energy storage technology that could play a critical role in Britain’s low carbon energy future. As things begin to take off for Dearman and Liquid Air, Heidi Vella speaks to the inventor and also the company director, Toby Peters, to find out more.

Tehran Times - Liquid Air - the future of motoring?

Dr. Andrew Atkins, Ricardo’s chief technology engineer, says the Dearman engine is also highly suitable for use with the Atkinson or Miller cycles to improve efficiency. And Colin Garner even posits future examples of the Dearman engine which could be built of low-cost plastics or alloys, which would give significant price advantages compared with complex batteries. Such a drivetrain would also have significant end-of-life recycling advantages compared with batteries.

The Telegraph - Liquid Air – the future of motoring?

Liquid Air could be be a fuel for the future, says Andrew English.

Certainly the idea has potential. Just one litre of viscous blue cryogenic liquid air, stored in a vacuum flask is the equivalent of 700 litres of atmospheric air. On release the liquid quickly boils, expands by 700 per cent and returns harmlessly back to the atmosphere. It’s that expansion that can be used to drive turbines, or piston engines such as the Dearman Engine. “Engineers like that expansion,” says Colin Garner, Professor of Applied Thermodynamics at Loughborough University, “they can do things with that.”

GasWorld - Liquid air could unlock £1bn business and 22,000 UK jobs

Published by the Centre for Low Carbon Futures (CLCF), the report concludes that liquid air technologies could also significantly increase the efficiency of road vehicles, particularly in Britain’s fleets of buses, vans and refrigerated lorries.

The Dearman Engine is a piston engine that runs on liquid air, with a commercial demonstration engine is currently being built with Ricardo. Meanwhile, the Ricardo split-cycle engine is a highly efficient diesel design that uses liquid nitrogen to capture heat from its own exhaust. Liquid air technologies require no rare or expensive materials such as lithium or platinum.

Green Car Congress - Liquid Air Energy Network forms in UK; focus on transportation

The report calculates that a vehicle food refrigeration system using liquid nitrogen or liquid air to provide both additional shaft power and cooling would cut emissions from 47 tonnes per truck per year (diesel refrigeration) to 10 tonnes, a reduction of almost 80% on the basis of current grid average electricity. The same approach could also provide refrigeration or air conditioning for passenger ferries, cruise ships, freight trains and buses, with greatest benefits in hot climates.

E2B - Liquid air could boost UK energy security, help decarbonise transport

According to a report by the Centre for Low Carbon Futures (CLCF), liquid air could reduce diesel consumption in buses or freight vehicles by 25 per cent using a liquid air Dearman engine/diesel hybrid.

The report says that in all but one scenario, per-kilometre costs for a car running on liquid air would be lower than for a petrol car with average UK fuel economy, and while electric vehicles such as the Nissan Leaf have lower running costs, the capital costs of a liquid air car would be around those of a car with an internal combustion engine, with the potential to be lower in the long-term, due to the fact that the engine can be produced from lighter materials.

H&V News - Royal Academy of Engineering to host conference on Liquid Air

The new white paper, Liquid Air in the future energy mix: A new industry for UK plc, investigates whether liquid air could provide a credible alternative to existing energy storage systems and low carbon transport solutions to better harness renewables and deliver energy security. It also considers the potential economic value to UK plc.

ABC News - Car Runs on Nothing But Air

By choosing liquid air, Dearman believes he has created one of the most sustainable cars on the planet. His engine is very light, allowing manufacturers to build a car that could be made cheaply, and, perhaps, out of plastic - no metal required. And by not using any batteries, manufacturers can avoid using any scarce materials.

Soon, his homemade invention will be put inside a very professional package.The engineering company Ricardo, which helps design engines for, among others, McLaren race cars, is creating a state-of-the-art version this year.

CNN - Make, Create, Innovate: Liquid air future fuels garage inventor

Watching Peter Dearman at work amid the clutter in his garage cum workshop it’s easy to see why one of his sons refers to him as a sort of “nutty professor.” The British inventor has been tinkering with “liquid air” engines at his home in Bishop’s Stortford, Hertfordshire for more than three decades. All that hard work is now starting to pay off.

The Economist - Difference Engine: End of the electric car?

A COUPLE of dozen electric cars with fuel cells under the bonnet (in place of the more usual flat-pack of batteries beneath the floor) have been zipping around your correspondent’s neighbourhood for the past few years. Most are FCX Clarity models from Honda, all in the same rich crimson colour. A couple of others are silver F-Cell station wagons made by Mercedes-Benz. These experimental vehicles are leased to selected users for trial periods while their manufacturers see how the hydrogen-fuelled cars survive the cut and thrust of Los Angeles’ traffic.

Professional Engineering: Liquid air made a splash

Liquid air made a splash. Sadly it’s not often that an engineering story – unless it’s a nuclear reactor going into meltdown or an aircraft downed by a birdstrike – gets a lot of airtime in the mainstream media. But yesterday’s carefully co-ordinated effort by the IMechE, Highview Power Storage, a number of academics and the automotive engineering consultancy Ricardo to make the world sit up and pay attention to liquid air paid off.
