The first hydrogen ambulance will come to London later this year built by conversion specialist Ulemco. Named Zerro (short for Zero Emission Rapid Response Operations), Ulemco teams up with Lyra Electronics, Ocado and Promech Technologies for realising the fuel-cell-range-extended EV.
Ulemco aims to deliver the Zerro prototype to the London Ambulance Service NHS Trust in autumn. Currently in production, the fuel cells for the hydrogen ambulance come from Ballard with 30 kW. There is also 8-kilo hydrogen storage and a 92 kWh battery onboard with Promech Technologies adding its existing battery technology and expertise.
