Toyota is developing a hydrogen-powered car which could be fuelled for a year by the manure of a single cow, bosses have claimed. Chief technology officer Shigeki Terashi said a cow’s droppings can be converted to produce enough hydrogen to run its next-generation Mirai saloon for 12 months. The concept car uses a “fuel stack” to transform liquefied hydrogen into electricity with water as the only byproduct, making the technology zero emission. Toyota is yet to offer a pure battery electric car and the company – which makes about 10 million vehicles a year – is seen as lagging behind rivals in the field such as VW Group. This is despite Toyota being responsible for the first mass-market hybrid electric car, the Prius, which cuts emissions by collecting energy from braking and storing it in a battery to assist the vehicle’s conventional engine.

Analyst WoodMac has spelled out the urgent need to decarbonize the global hydrogen production industry. While the fuel can offer a sustainable grid balancing act for intermittent renewables, in its current fossil-fuel driven form it is pumping out more than 800 tons of carbon into the atmosphere every year. Green hydrogen production will be able to compete on cost with fossil-fuel hydrogen by 2030 in Australia, Germany and Japan – but only if renewable energy prices continue to tumble or more policy levers are pulled. That is the chief finding of a report published today by Scottish analyst Wood Mackenzie, which predicted the 252 MW of green hydrogen production capacity expected worldwide this year will expand to 3,205 MW by 2025. The urgent need for renewable-energy produced hydrogen was explained by WoodMac not only as an energy storage grid balancing alternative to fossil fuel power plants but also because of the hugely damaging CO2 emissions created during the production of hydrogen at present for use in other sectors.
