British Company Developing Home Electrolyzer for Hydrogen Production; Dual-Fuel Conversion Offers Hydrogen Range of 25 Miles

A British company is developing a low-cost home electrolyzer for the production of hydrogen to refuel a converted dual-fuel vehicle that uses both low-pressure hydrogen and gasoline.
The ITM Power electrolyzer uses a 10 kW electrolyzer operating at 75 bar pressure. ITM Power modified a gasoline engine Ford Focus to make it a dual-fuel vehicle, and has fueled the converted car with the output from the electrolyzer.
The refueling is also only at 75 bar, compared to the 350- to 700-bar storage systems being developed for hydrogen fuel cell vehicles. As a result, the hydrogen on-board the converted vehicle is limited, and supports an all-hydrogen range of about 25 miles before switching back to run on gasoline.
That distance, says ITM Power, is more than the more than the average commuting distance in the UK.
The bi-fuel car and refuelling system clearly demonstrate a simple, convenient and low-cost transportation solution that can significantly reduce greenhouse gases and help mitigate climate change. We believe combining electrolyzers with an internal combustion-engined vehicle brings affordable hydrogen transportation forward by many years.—Jim Heathcote, ITM Power CEO,
Both the refuelling system, which will be able to generate and store hydrogen at home or at work, and the dual-fuel car will be demonstrated publicly later this year. Meanwhile, ITM Power is finalizing the design of a manufacturing facility in Sheffield which will deliver one of the largest electrolyzer production capabilities in the world. Manufacturing is expected to commence as early as the first half of next year.
