Notes:
1. Total number of hours of vehicle operation until end of life (assuming >98% availability in the fleet in heavy duty 3/7 or 3/5 shift operation).
2. Hydrogen consumption for h of operations using exclusively hydrogen feed for Class 1 forklift load cycle @ 10 kW avg. system power output (Begin-of-Life)
3. Percentage (%) of electricity generated by the fuel cell vs. energy contained in the hydrogen delivered to fuel cell (LHV) for Class 1 forklift load cycle @ 10 kW avg. system power output (Begin-of-Life)
4. Percent amount of time that the forklift is able to operate versus the overall time that it is intended to operate.
5. Average time between successive failures leading to downtime (MTBF in the fleet in heavy duty 3/7 or 3/5 shift operation).
7. Costs for spare parts for the system maintenance as percentage of system investment over the vehicle's complete lifetime.
8. Man-hours of labour for the system maintenance per 1,000 h of operations over the vehicle complete lifetime.
9. Actual cost of the fuel cell system - excluding overheads and
10. Estimated fuel cell system cost at an assumed up-scaled production level of 2024: 20,000 units/production & 2030: FC cost level benefits from automotive, bus and truck volumes.
