One more reason to buy an EV...smog checks are not necessary.

@mahonj: Many are predicting road transportation in the future will be via self-driving taxi services.

There are two general ways to use hydrogen; directly as a fuel source in ICEs and in fuel cells to generate electricity to drive electric motors. The downside when used in ICEs is the efficiency at best is about 25% and it produces NOX. The upside it does not produce CO2, only water. When used as a compressed gas in a fuel cell the only residue is water; however, the efficiency is still less than 55% and it is expensive to produce and transport to the user. Currently it is produced from natural gas that is reformed, using great amounts of steam and heat; then it must be mechanically compressed to as high as 10,000 psi. This adds greatly to the cost and danger of usage. Nevertheless, H2 fuel cells makes sense in applications where gross pollution can be offset, i.e., in jet engines and the huge diesel engines used in sea ships.

BEV ground transportation, including trucks and buses, has advanced to the point that ICEs are no longer necessary; I've driven a BEV for the last 10 years and just traded it in for another; the added complication of adding an ICE to create a hybrid just prolongs the transition to clean energy. I know it's difficult for some to let go of the ICE because its been around for a hundred plus years; but, once you move to BEVs, you will never look back. Air travel and sea ships are the only large segments left to clean up and until battery technology advances, hydrogen/electric looks to be the best bet.

The IMO has been missing in action for decades and when they finally appear they just extent the time line for continuing gross pollution by sea ships...the ports should get together and agree to charge a port fee to bunker-burners. an ever increasing fee until the ships change over to clean energy. Make more expensive to pollute than to change over and they will do something about the problem, otherwise they are very happy to just keep screwing up the World.

All sounds good except the timeline isn't...looking ahead to the middle decade is a long time in today's car business...Tesla and VW will have run away with the goods by then. I think all the U.S. makers will lose a large part of the market because they cannot move fast enough

To bad it takes a Government money boost to get companies thinking in the right direction; but, it works.

A good solution; much better than dirty diesels.

Makes sense to use School buses for VtoG if you install a large enough battery that will cover their delivery duties and grid requirements.

Great stuff! BTW, where is that Tesla Semi?

My first thoughts are: 'Much too late,' however, natural gas is going to be with us for a long time yet as power generation backup if nothing else. So, the cost of the research isn't wasted; and , if there are resulent methodologies developed that reduce recovery costs and reduce the amount of pollution, then it's all positive..

H2 FC ot BEV? If battery tech improves enough, there will be little need for FCs in 18 wheelers, just batteries and large quick chargers.

Resistive heat or a heat pump? I like the heat pump because it's more efficient.

Good to see H2 and FCs moving into sea ships; aircraft are next.

Electric motors, motor controllers and inverters in BEVs are becoming smaller and less in weight as the technology advances; and, this drives their use in the other segments where weigh is a chief concern, i,e,. aircraft, I would hope they never stop trying to make all components more efficient. smaller and lighter. And, I hope we can do better than a 15% gain in energy density for the batteries, otherwise developing clean battery powered air transportation will continue to be a struggle, Where are those battery breakthroughs we need?

H2 has not proven to be practical for ground transportation because it takes so much energy to create and store it.

There is no data that H2 ground transportation is feasible. This is the results of lobbying on behalf of Big Oil...for promised campaign funding, no doubt.

I hope in the future, battery technology will be such that changing out individual battery modules and cells won't be the complicated, huge task it is today. Perhaps access thru the floor and under the seats will be possible when cells are more energy dense and smaller in size. Having to deal with thousand pound 4 by 6 battery packs is APITA.

Now that Joe Biden is in the WH, we can get back to solving the clean energy problems of the Nation and building back the middle class.

Trucks with 'one petal driving' are truly possible using EV drivelines; diesel trucks burning oil and needing 10 to 18 forward gears are now obsolete.

Europe has the march on the US because they have a clearly defined path to clean energy; we on the other hand are still suffering from an unstable central government flailing around in the dark trying to bring back fossil fuel against the advice of the many scientist pushing for clean energy. Hopefully, this problem will not continue much longer.

Same old problem; if the H2 is created from electricity and water that all good...from fossil fuel by reforming, not so good.

SJC: Gasoline/Diesel has a tax above $5 a U.S. gallon (adjusted from liters). Don't know about LNG. Plus the Euro oil companies gather subsidies of about 55 billion a year while the U.S. fuel companies enjoy subsidies from the U.S. tax payer of about 16 billion a year. We all are being robbed blind by politicians hired by big oil. It's been estimated that the total subsidies for the oil industry approached one trillion dollars.

Interesting to watch GM offering their premium vehicles as their first serious foray into EVs...way out of finance range for most of us.

I thought that wireless charging would be inefficient; not the case...ac magnetic resonance charging for EVs is about 93%-95% efficient...this may be a technology that will advance rapidly and might prove to be a good investment.
