[TOKYO] Nissan Motor Co said on Tuesday it was developing fuel cell vehicle (FCV) technology using ethanol as a hydrogen source in what would be an industry first, and planned to commercialise its system in 2020 as part of efforts to develop cleaner cars.
The Japanese company said using ethanol, produced from crops including sugar cane and corn, to generate hydrogen-based electricity inside vehicles would be cheaper than fuel cell technology developed separately by rivals Toyota Motor Corp Honda Motor Co, and Hyundai Motor Co.
"The cost and energy required to produce hydrogen can be very high, and it also requires significant investment in (fuelling and storing) infrastructure," Nissan Executive Vice President Hideyuki Sakamoto told a media briefing.
"Compared with that, ethanol is very easy to procure, it is safer to store and lower cost. These are its merits." Nissan said its technology would be ready for use in vehicles in 2020, adding it could be used to extend the range of larger, electric vehicles such as delivery vans.
It would target a cruising range of around 800 kilometres per fuelling, more than the range for gasoline-powered vehicles of just over 600 kilometres.
The automaker said running costs for the FCVs would be roughly similar to those of electric vehicles, while declining to give details on vehicle pricing.
Ethanol is used as a fuel source for vehicles in countries including Brazil, but Nissan is planning to use it to generate electricity in fuel cell stacks to charge batteries which would power vehicle motors.
In developing its FCV technology, Nissan joins Toyota and Honda in a national, government-backed drive to develop a "hydrogen society", in which the zero-emission fuel would be used to power homes and vehicles, and reducing Japan's reliance on imported fuel sources and nuclear power.
Toyota began marketing the Mirai, its hydrogen FCV, in late 2014, while Honda earlier this year began sales of its Clarity Fuel Cell vehicle. Initial production for both models has been limited due to their relatively high cost and limited fuelling infrastructure.
Unlike its rivals' offerings, Nissan's technology does not require hydrogen to be stored in vehicles, reducing the need for expensive bulky hydrogen tanks, and would not require fuelling stations, which have been slow to spread globally.
