Officials at Japan's transportation firms are looking at ways to support a government campaign for a carbon-free society.
On Monday they tested out a vehicle that could make a big difference -- a hydrogen-powered fuel-cell truck that emits no carbon dioxide.
Company representatives put the vehicle through its paces at the event, organized by the industry ministry and other parties.
The truck is the creation of Japanese automakers Isuzu and partner Toyota. The firms say it can get 260 kilometers on a 10-minute charge.
Fuel-cell vehicles have a longer cruising range than EVs and are expected to play a big role in long-distance trucking.
One attendee said he's impressed by how smooth the truck feels. He said it puts less stress on the driver's body, and hopefully will help reduce accidents involving truck drivers who work long hours.
Japan's energy conservation law says that by 2030, 5 percent of trucks at big transportation firms should be hydrogen fuel cell or electric.
Government officials say there are currently plans to put about 300 fuel-cell trucks on the road this year in areas that include Tokyo and Fukushima prefectures.
