A POWYS inventor has unveiled a zero-emissions internal combustion engine, which he says could be a game-changer in the fight against climate change.

Steve Berrow, from Crickhowell, has built and patented Berrow-Zeice - a hydrogen-powered internal combustion engine which takes in no air and delivers no exhaust - resulting in zero emissions.

Mr Berrow has had a long and varied career in the energy field. He designed, built and ran a biodiesel micro refinery in Tredegar and also made the bio fuel that ran the London leg of the 2007’s Live Earth concert.

Current emissions-free vehicles either run on lithium batteries or hydrogen cells, the downside of both being the environmental impact of building new automobiles. Other downsides include the newfound  battery “electric stress” and the eye-watering cost of hydrogen cells for the consumer.  

Mr Berrow says that Berrow-Zeice delivers 100 per cent fuel burn with zero emissions, delivering efficiency for drivers and a potentially world-changing reduction in carbon emissions.

Crucially, he says that the innovation can be adapted to any engine - petrol or diesel, big or small.  

Mr Berrow said: “This is truly a global gamechanger for the fight against climate change  and I’m so excited by my innovation because, I know that it works, I know how it works and why it works. 

“Our technology can, if adopted, reduce the damaging impact of toxic emissions and have a significant positive impact on public health and the environment at large. This unique system has no air intake and no exhaust and to see the engine effortlessly spinning at 2000 rpm for hours on end and only  emitting a small amount of water is absolutely amazing.” 

“Imagine a building site or motorway construction, a rail side or tunnel development, an outside event  or backup power generators for hospitals, supermarkets, businesses and in fact any mission-critical  service, they all have a need and use for power generators. This is either to be the main source of  power or backup to a principal power source. All of them currently pump out into the atmosphere  harmful toxic gas emissions – some 24 hours a day, some on-demand or supporting other power  supplies.”

Mr Berrow says that this technology can applied on a variety of scales.

“Whether you’re a nation-state or a local council with climate change agendas and clean-air zones or a  business with strong boardroom mandates to cut Co2 emissions, adopting this technology will ensure  we and future generations all benefit not by purchasing carbon credits but by cutting real-life emissions,” he said.

“The time for talking is over. It is now time to embrace this new technology and usher in the hydrogen highway.”
