Toyota's hydrogen powered bus

Toyota has announced today that they will start selling buses that run on hydrogen fuel-cells in Tokyo next year before the start of the 2020 Summer Olympics. A hydrogen powered bus in itself is not that interesting, but the bus has a different use — doubling up as a high-powered external power generator.

Toyota’s fuel-cell buses will run on up to 10 fuel tanks holding 600 litres of highly pressurized H2 and producing 235 kwh, or almost three times the output of a Tesla Model S battery. This is what allows the bus to double up as an external power supply.

The goal is to sell up to 100 buses in Tokyo before the start of the summer games. The Japanese government has said that it would be spending up to $6 billion to bolster Tokyo’s transportation infrastructure, including new roads and airport, rail, and port upgrades.
