Hydrogen infrastructure

[Torvy]

good for you

here forecasts are for the-guy above you...to give to the guy above him...for the guy above him....so he can tell his boss.

i worked in sales dealing with huge companies and lots of $ and programs that lasted years and, based on my experience, the notion that a forecast is used to plan, imho, is fantasy.

i'm glad they do it in scandinavia.

True for Sales, pure fantasy. Operations, on the other hand often live or die by accurate forecasts.

Back in the '80's, I worked on a hydrogen vehicle platform at GM using a fuel cell to power an electric car. The EV1 was supposed to receive such a cell (joint venture between GM & Cornell University & BMW). But, the State of Kalifornia backed out of an agreement to allow hydrogen fueling stations for these vehicles. A major concern in the design was the 5000 psi hydrogen tank needed to get a decent customer acceptable range out of such a vehicle. (The energy density with carbon based fuels is exceptional, hydrogen, not so great). A fueling station would swap tanks, not fill them. The crash concerns also helped kill it, not from fire (the colorless hydrogen fire quickly goes upward and away from the wreckage unlike gasoline) but from the concussive force of the explosion. This concern was not just for occupants, but for EMS, Fire, and Safety personnel. The goal was to have a small car and a pickup truck running with 4 electric motors. BTW: the State of NY also came up with an idea from the past when horses were scared of cars. The EV's were too quiet, so you had to have a periodic noisemaker to warn pedestrians of your approach.

Anybody notice the new concerns about the high (450) voltage in today's electric cars ? Mercedes has issued a warning/requirement that Safety personnel must wait at least 1 minute after a crash, for the battery and electrical component damage to settle out. If you run into one, don't let anybody lick the terminals.

I may have to print this off and tape it to my first aid kit. A good reminder if I come across an accident... Do I lick those terminals to deactivate them?

With you there... I was used to getting beaten with rubber-hoses here, over deviations from forecasts....

One of their markets is as a supplementary fuel, added to diesel.

Similar focus in the UK, looking to add to natgas for residential use. Gives some small reduction in emissions, w/o having to do major re-piping etc. as the hydrogen content is relatively low.

Hazards..... always hazards.

Interesting snapshot of a now-vintage engineering project.

Pedestrian made me smile, thinking of today....... since the majority of pedestrians are now walking along staring at their phone, should EVs just broadcast near-field warnings as they go down a street ? Joking, but not totally....

Some feel that a car should jam cell phone signals as soon as it's put into gear. Perhaps extend the range outward, based on speed.

But, but, how would people know how to get places?

I don't often find myself agreeing with Kalifornia, but hydrogen storage tanks at 5000psi and moving down the road at 75mph, do provide some major risks on a highly mobile vehicle moving at speed, and often driven by drivers who are often Distracted or DUI or simply lack the emotional maturity to drive. In the future, i believe hydrogen fuel cells are going to form a significant portion of the US electrical power, but mainly from stationary power centers only. Though Toyota (Mirai) and Honda (Clarity) are still conducting quality research on hydrogen fuel cell powered cars, both are slowly moving away from fuel cells and moving towards EV only.

And Elon Musk, who has a "Future Strategy Team" composed of some of the best trained scientists around the world as his direct advisors, just cannot get past the dangers and potential liability of the 5000psi hydrogen storage tank. Tesla closely looked at, evaluated and walked away from hydrogen fuels cells in cars due to potential risks. I can understand that decision.
