Six hydrogen fuel-cell electric cargo bikes are to be trialled for last mile deliveries in Aberdeen. The Oxfordshire EAV e-cargo-bikes are set to be trialled later this year to test the use of hydrogen fuel cell vehicles in last mile deliveries.
One of the drawbacks of batteries is their weight for a given amount of range, according to EAV, that adds the company has questions as to the environmental sustainability of battery electric vehicles too.
“It’s a simple fact that the raw materials for battery production are in short supply.” said Adam Barmby, CEO and founder of EAV.
“EAV focuses on weight reduction, so we use less energy and therefore require less batteries.”
The EVAH2Cubed e-cargo-bikes have the fuel cells in their powertrain, using the electricity generated to charge batteries. These release the energy at the speed required to power the vehicles using a similar system to battery e-cargo-bikes.
“The Transport Secretary, Grant Shapps, recently delivered a speech at the Dubai Expo 2020 stating that the UK will be taking a global lead in developing hydrogen-powered transport.” said Nigel Gordon-Stewart, executive chairman of EAV.
“Nowhere is the use of hydrogen fuel cells in lightweight vehicles more effective than within the urban environment.”
There are some drawbacks to hydrogen, especially on smaller vehicles like cars and bikes. Even when compressed to the level required to make a fuel cell work, H2 can be very bulky. At the same time, far more electricity is required to store a similar amount of energy than would go into batteries – fuel cell vehicles are typically 30% efficient as opposed to in the region of 90% efficiency when it comes to a battery electric vehicle. Finally, 90% of hydrogen on the market today is extracted from fossil fuels with similar emissions to that of petrol and diesel. Until more green hydrogen comes on the market, H2 is a bit of a ‘greenwashed’ concept..
