KEYOU
KEYOU suggest that HICE technology can go "12 times as far as vehicles with batteries of the same storage weight", meaning the technology allows the same vehicle payload as diesel engine vehicles and KEYOU suggest their HICE system offers a similar range.
- Short refuelling time for hydrogen systems vs battery charging.
- HICE operational lifetime with maintenance will likely be on a par with diesel engines, which last the lifetime of the vehicle. For battery and fuel cell systems the forecast operational lifetimes are shorter than the usual operational lifetime of the vehicle.
- Positive strategic investors NAGEL and partnerships (DEUTZ, Liebherr Group (unconfirmed), Mammoet.
