I thought it was obvious I was comparing BEV vs FCEV. Apparently not. > Higher cost to build? Well, yeah. But don’t BEVs cost more to build, An FCEV is an EV with a fuel cell, so most of the extra BEV costs are still there (still needs an electric motor/controller/batteries/etc) You say a little by using a smaller battery pack but then spend a LOT more of the fuel cell, tank(s), etc.
> Higher cost to operate. For the consumer? Really? Compared to an BEV? Yes, absolutely, much higher. It gets even worse if you use green H2 since it requires about 3-4x as much electricity per mile to make the H2 vs charging an EV. > Lower efficiency. Lower efficiency of what, and to whom? Miles per kWh. To EVERYONE. Modern LiIon batteries are about 90% efficient at storing energy, chargers are also around 90%, equaling roughly 80% efficient at stroing electricity (and that can be improved) Modern electrolyzers are around 80-85% efficient and fuel cells are around 60%, which means a combined efficiency of ~50%, and that does NOT count any energy used to compress the H2, which front what I've read brings the total storage efficiency down to around 25-30%...at best. You'll also have additional losses charging/discharging the batteries on the FCEV. > > No existing infrastructure. Again, this all depends. If you have access to a > station and 5 minutes > to fill every 300 miles or so, that’s plenty . Currently there are less than 40 public H2 stations around LA. There are zero H2 stations anywhere else in the USA. Currently, in the USA, there are over 1,000 public charging stations for every public H2 station. This number is increasing because while they are constantly installing new EV charging stations, they are shutting down H2 stations. For all intents and purposes, there is NO H2 fueling infrastructure in the USA, while Public EV charging stations are becoming common acrost most of the USA. Extremely common on the coasts. As stated above, if you are cracking water for you FCEV, then it takes 3-4x as much electricity per mile to charge at home (compared to a BEV) The weight of modern FCEV is roughly the same as the weight of comparable BEVs, so that's not an advantage to either. They have EVs available today that can recharge almost as fast as refueling a FCEV, and you can hook up the charge cord yourself, from what I've read every H2 fueling station requires a trained individual to connect the hose. Waiting for him/her to show up could elliminate the remaining time advantage. Consumers won't purchase FCEV unless they perceive and advantage TO THEM. Let me put it simply, what advantages do YOU see to ANYONE other than the folks that make H2? How do you see these advantages making FCEV economically viable? Viable enough to justify creating a nation wide H2 fueling infracstructure from scratch? _______________________________________________ Address messages to ev@lists.evdl.org No other addresses in TO and CC fields UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/ LIST INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org
