For a somewhat different and more positive take on sustainable H2's long-term prospects, GCC had an article a couple of days ago. Haven't figured out how to link it on my phone, but the title starts "BNEF report finds hydrogen promising decarbonization pathway", and also lays out the issues that will need resolving to get there, not just for transport but also for things like steel, cement and ammonia production, all of which will need to be made without fossil fuels.

Out away from buildings and people is a great place for it. Finally they get it.

GCC:
SGH2 building largest green hydrogen production facility in California; gasification of waste into H2

Energy company SGH2 is bringing the world’s biggest green hydrogen production facility to Lancaster, California. The plant will feature SGH2’s technology, which will gasify recycled mixed paper waste to produce green hydrogen that reduces carbon emissions by two to three times more than green hydrogen produced using electrolysis and renewable energy, and is five to seven times cheaper. . . .

SGH2 says that its green hydrogen is cost competitive with “gray” hydrogen produced from fossil fuels such as natural gas—the source of the majority of hydrogen used in the United States.

The City of Lancaster will host and co-own the green hydrogen production facility, according to a recent memorandum of understanding. The SGH2 Lancaster plant will be able to produce up to 11,000 kilograms of green hydrogen per day, and 3.8 million kilograms per year—nearly three times more than any other green hydrogen facility, built or under construction, anywhere in the world.

The facility will process 42,000 tons of recycled waste annually. The City of Lancaster will supply guaranteed feedstock of recyclables, and will save between $50 to $75 per ton in landfilling and landfill space costs. California’s largest owners and operators of hydrogen refueling stations (HRS) are in negotiation to purchase the plant’s output to supply current and future HRS to be built in the state over the next ten years. . . .

SGH2 anticipates breaking ground in Q1 2021, start-up and commissioning in Q4 2022, and full operations in Q1 2023. . . .

We'll see if the bolded section turns out to be true, always assuming the plant gets built.

Once again production is up against a wall of efficiency. Even is nice but really need to find a way to undercut by 50% and improve from there. The rent is just too damn high.

Efficiency is important, but so is capability, which is why far less efficient fossil-fueled ICEs won out over BEVs. Maybe BEV capability will increase to equal that of H2 FCEVs, but I've long felt each ZEV tech will find the niche where its advantages are most important, or we'll see hybrids of the two (PHFCEVs) where both are important. Assuming roughly equivalent economies of scale and costs, of course.

So, BEVs for local cars, buses, yard locomotives and truck P&D/regional distribution where weight and flexibility aren't an issue, FCEVs for long haul trucks, trains, buses and ships and maybe regional airliners, and PHFCEVs for all-around cars.

1st development phase of Autostack Industrie project for commercialization of fuel cell stacks complete

https://www.greencarcongress.com/2020/0 ... 26-ai.html

. . . The ongoing project, which began in 2017 and runs until the end of 2021, is pursuing three main objectives:

Automotive high-performance technology: highest power density including lower platinum loading, complete project maturity, achievement of automotive target costs;

Exploitation of industrial economies of scale: joint FC specification and system interfaces, scalable FC output, common technological platform; and

Mass production capability: selection and evaluation of critical processes, achievement of automotive quality requirements, plant planning for 10,000 and 30,000 stacks per year. . . .

. . . Air Liquide introducing next-gen hydrogen stations

https://www.greencarcongress.com/2020/0 ... 26-al.html

Air Liquide is introducing next-generation hydrogen stations with a high capacity of 1,000 kg and dual filling positions capable of filling 250 vehicles per day. Air Liquide’s high capacity gaseous hydrogen station can provide 700 bar fills at T40 temperatures per SAE J2601 protocol.

Air Liquide integrates compression, high pressure storage, and cooling on a single skid. Not only does this reduce the overall footprint, but allows for an easier installation.

The station skid measures 28' x 9'6" x 13'4'. Its footprint does not include hydrogen source/storage, dispenser(s), or utilities. . . .
