Several industrial companies in Scandinavia have banded together to develop a hydrogen driven fuel cell for freight trucks. When a lorry driver is resting at night, the diesel engine of the vehicle is run in neutral to power heat, lights etc for his cab. The new fuel cell will be like a mini-power station providing energy for all these ancillary facilities, but as it is hydrogen driven it produces no CO2 emissions. It should also be able to power fork lift trucks without needing any other power source. If this is developed on a commercial level, it will drastically reduce the emissions caused by the freight industry.
