Clean air technology used in rockets and submarines promises greener and cheaper motoring

By July 21, 2016January 26th, 2021Member News & Updates

Specialist technology used by NASA and the Royal Navy to produce clean air in rockets and submarines is now available to motorists in the form of a neat device measuring a quarter the size of a car battery which, when fitted to an engine, radically reduces carbon emissions and cuts running costs.  

The inventor of the E-zero1 is Exeter-based Brian Sheard who, when serving as a Royal Navy submariner, was responsible for monitoring and maintaining an electrolyser aboard a Hunter-Killer class vessel. At the time he suspected there could be a much wider benefit from the technology which converts sea water into oxygen, providing crew with an essential oxygen supply via an air purification system.  

After leaving the service, Brian joined forces with motor trade entrepreneur Mark Fox and the pair spent several years researching fuel economy technologies while running a garage, convinced that the unique emission reduction technology would reduce harmful motoring emissions.

Through crowd funding platform Crowdcube and other private investments, the duo raised over half a million pounds to bring the product to market and E-zero1 is now manufactured in the UK and distributed by Brian and Mark’s Exeter-based company Cgon and installed by 14 installation centres across the UK. 

The E-zero1 has been extensively tested and is proven to reduce harmful pollutants by up to 80% and improve fuel efficiency by up to 25% for every fuel powered car, van, bus, marine and motor vehicle on the market.  The product also reduces engine running temperatures and hydrocarbon build up, prolonging the life of Diesel Particulate Filters (DPF) on diesel cars. The system is available to haulage companies and HGV drivers with a specially designed model, the E-zeroH1, for use on larger motor vehicles.  

The latest company to trial the innovative technology is Stobart.  Stobart have been in trials using Cgon technology for the last 6 months and the results have been positive, with good improvements in MPG and reductions in CO2. Stobart are delighted and looking forward to a positive working relationship with Cgon.

In addition, later in the summer Cgon Managing Director Mark Fox has meetings booked at the European Parliament to discuss Cgon’s products with the Environment, Public Health and Food Safety Committee (ENVI) and Julie Girling MEP.

Director Brian Sheard said: “The technology used in the E-zero 1 is not brand new by any means. NASA have been using it in rocket technology for over 40 years, but we have added new materials, modern electronics and innovative design to create a product that exceeds all previous examples of this device that is currently available on the market today.

He continued: “There is huge potential for this product, not only will it help improve fuel efficiency and reduce people’s motoring costs, it will help to reduce harmful emissions and have a positive impact on people’s health through the quality of the air we breathe. In this country alone there are around 32 million vehicles which could use this product and we are already talking to Governments in other countries who want to tackle air pollution.”

Mark Fox, Cgon Managing Director said: “Carbon emissions and pollution are at an all-time high, causing numerous health issues and causing damage to our environment. Fleet vehicle owners and taxi companies that install the E-zero1 in their vehicles will make huge savings, whilst dramatically reducing their impact on the environment. A product like this has been a long time coming to the commercial market.”

There are 14 installation centers across the UK from Cornwall to Scotland, all of which have been carefully selected for their industry expertise and expert knowledge. Each centre has attended a fully comprehensive training course to fully understand how the unique system works and how to get the best results.

The patent protected technology used in the system accelerates the fuel burning process in internal combustion engines, achieving near total combustion of the fuel.  As a result, it radically reduces emissions of harmful chemicals such as Nitrous Oxides (NOx), Particulate Matter (PM) and Carbon Monoxide.  Test results on a variety of different vehicles can be found online at
