Marketing? At first: for gas cooking/heating. Many of these now use bottled propane delivered to large white tanks near consumers. Heating-hydrogen’s transportation need only be, like other heating-gas now, from local fuel dealer to consumer.

For early evolution toward cars, heating-gas trucks, and other applications, existing gasoline or diesel engines could use the fuel. Kits: with small pressure tanks, ignition timing adaptation (if needed), tubing, fittings, instructions, etc., could eventually permit it.

Adverous, pioneering “garage engineer” tinkerers would find fuel at these heating hydrogen suppliers. This could eventually begin gently establishing hydrogen fueling stations for new, plug in free, fuel cell electric cars, like General Motors’, series electric “Sequel” concept car.

Further evolution could move toward, more convenient, roadside locations, that gasoline and diesel now use.

Some say electrolytically separating hydrogen from water requires fossil fueled electric grid reinforcement, and still more fossil fuel to transport it to fueling stations/dealers, adding CO2 from every stage, just to use a fuel that, itself, burns without making CO2, effectively eliminates hydrogen’s atmospheric CO2 reduction.

Does it?

Can’t photovoltaics (PV) power electrolysis – off-grid? PV’s unchanged direct current powers electrolysis without expensive, power-losing electronics to adapt gridpower’s alternating current. Storing hydrogen in pressurized tanks, makes production after dark unneeded.

Why transport motor fuel, when made from energy produced where sold?

Gridpower could continue supplying the station’s lights, tools, etc.

Offering standard, inexpensive kits of:: PV panels, electrolyzers, a compressor, instructions, etc., hydrogen infrastructure could be established, station by station; if desired, even at home.

The “chicken-or-egg” question needn’t delay introducing hydrogen powered fuel cell cars.

The main benefit of Diesels are a 50% fuel burn efficiency compared with 27%[18] in the best gasoline engines.[15] Germany’s first mass-manufactured…

I am putting a large array of solar panels on my roof and will charge my car (and power my house) with it. I have extensive experience with solar and love it – no moving parts!

Secondly, I live in an agricultural area of California (coastal). I plan to collect free agricultural waste (parts of plants such as brussel sprouts, strawberries, etc. that are thrown out) and produce bio fuel in a small home bio fuel production device.

Free battery charge. Free fuel. (except for infrastructure).
