@ change: Charging a heavy e-truck during 30+ minutes every hour will greatly reduce effective running time and will require about 50+% more trucks and drivers. An extended range (1000+ Km) hybrid with FCs could be a better solution? By 2030-2035 or so, 5-5-5 (1000+ KW) batteries may become another solution.
Fast-charging e-buses with Busbar, at each run-route end, use 10+% of useful run time or another 300 to 600+ buses and 750 to 1200 additional drivers in the fleet for large cities. This could change with (future) much larger batteries (400 kWh to 800+ kWh), good for one or two complete shifts. Larger battery packs weight and cost a lot more per extended range e-bus.
Could be ideal, specially in FCEVs, if it does not consume H2. Larger or more units in H2 buses could be ideal?
These new 350 KW charging facilities are getting closer to the level required to recharge extended range BEVs under 10 minutes. Another 350 KW (or 700 KW units) could do it?
A smart way to use standardized small H2 containers for large H2 stations. The same individual small containers could be used for buses, trucks, locomotives etc.
A good first step towards (clean) extended range FC Class 8 trucks. A hand to Toyota again.
Superior design with 3 e-motors and batteries in the right places and enough range for most users. Others will have o catch up?
Good design with batteries and e-motors in the right places and about enough range for many potential users.
sd: Yes, e-Buses or FC-Buses with 350 miles (about 500 KM) range could run for a full double shift most of the time. Can they be produced at a competitive price? If so, where are they used? Articulated (100+) passenger electrified units may solve drivers' very high cost.
There are at least six (6) barriers to widespread purchase of BEVs: 1. High (+40% to +60%) initial price. 2. Limited all weather range (mostly under 180 miles). 3. Limited (50%) home charging facilities. 4. Limited battery capacity and high cost. 5. Limited clean electricity (REs) in many places. 6. Slow charging (30+ minutes) at public stations. The arrival of 3X to 5X, much lower cost affordable quicker charge batteries and quicker (750 KW) public charging facilities, sometime between 2025 and 2035, will fix most of those shortcomings?
From 16.2%to 114% could mean an abundance of very low cost H2 in many sunny places (if it can be done in large units)
I fully agree with you that e-buses and FC-buses with enough range for 8 or 16 hours use could be ideal to replace current diesel polluting units. Unfortunately, the initial cost of those ideal units is still too high and would not be competitive (yet).
Total city e-buses operating cost is very misleading. Montréal QC first city e-buses spend/require 6+ minutes (per hour) or 10+% of the time charging. Lower availability will require 300+ more buses and 750+ more very costly drivers. Charge times + extra buses/drivers + higher initial cost will more than offset potential savings.
The higher price, lack of home charging facilities and very limited range of current BEVs may be contributing factors (in Japan and many other countries)?
We use 3 Toyota HEVs in the family and with an average of close to 44 mpg we do as good if not better than equivalent diesel units and almost twice as good as equivalent ICEVs. Toyota's HEVs can operate over 300,000 miles without major maintenance. Brakes last 2 to 3 times longer.
Clean running improved higher power density FCs would be ideal to keep batteries charged?
This is good news and constitutes increased competition in the more efficient inverter field.
Current limited energy density, slow charge batteries are a real disappointment when used for electric city buses. The first Volvo-Nova Canadian made city e-buses are in operation in Montréal, QC. Those e-buses have to be recharged (for 6 minutes) at the end of each long route/run. This reduces effective operation time by 10+% and will translate into 300+ more city buses and 750+ extra very costly drivers. The extra buses and drivers will more than offset savings for diesel fuel and maintenance. Something like 5X batteries are required to reduce charging frequency to one (1) per shift.
Could 5X to 10X affordable batteries be eventually produced with this type or similar improved material? If so, today's EVs would would ALL have to be quickly updated and/or be replaced?
This is a very first mini-step towards adequate H2 stations in Toronto and in Canada. Many more hundred H2 stations will be required to promote the near term use of all weather long range FCEVs.
No real change in the last 3 years?
This JV will promote mass production and local use of(1,000,000+/year) much lower cost FCs for buses, trucks and FCEVs. Export to rest of Asia, EU, Americas etc is a strong possibility. Good news for near future lower cost FCs.
It will take another 10+ years for develop affordable sensors and appropriate software. Safe ADVs may not be common place before 2027/2030. We will have to live with bad drivers for another 10 to 15 years.
Total distance travelled in 200/2008 and 2016 was not very different. Higher fuel consumption must have been largely due to heavier less efficient ICEVs?
H2 avenue for future clean energy is evolving fast. This is just one more way of doing it. Eventually, REs + H2 + FCs will supply fixed and mobile clean energy 24/7 to replace Coal and Fossil Fuels with as much efficiency if not more..
