The Hydrogen Cars Technology

The hydrogen myth not yet dead? o_O H2 cannot be transported over long distances so the only option is to generate in at hugely expensive charging stations that haven't been built yet by means of electrolysis, using a bucket of electricity. Say efficiency = 60% = 0,6 Then you pour it into a hugely expensive car tank that has not yet been built and transform in into electricity again in a hugely expensive fuel cell that has not yet been built. Say efficiency ~60% = 0,6 (not accounting leaking - yes, hydrogen particles being the smallest ones do leak if not bound chemically just from any container). So the overall efficiency is 0,6*0,6 = 0,36 = 36% Impressive! And the car still has no battery to perform regenerative braking. ||| Meanwhile, you take a plug-in hybrid. Chinese have already started mass-producing one (BYD F3DM) for 22000 USD, with a battery covering ~60 miles to handle 95% of distances people drive on daily basis, promising massive battery life. Regenerative braking comes naturally. Overall charge-discharge-generate-power cycle for a battery and an electric motor is 80%. So instead of wasting 64% of your bucket of electricity, you just waste 20%. Instead of having to use massively pricey technology that does not exist, you use cheap one that's right here right now. Good luck with hydrogen then, which was the fuel of the future 20 years ago, is now and remain the fuel of the future in 20 years as well. Even if fuel cell cars owners farted hydrogen, it still wouldn't work.

We assume by default that motoring journalists know what they're writing about. This assumption fails to meet reality far too often.

The BMW Hydrogen 7 is not a fuel cell vehicle as the writer indicates. The BMW Hydrogen 7 is a dual fuel gasoline or hydrogen vehicle that can switch from one to the other at the press of a button. I've driven this car twice.

I’ve left additional comments at the bottom of the original article.

Ethanol,Biodisel,natural gas,hydrogen are such type of fuels which can be used to reduce vehicle emission and thus save our planet..Out of this hydrogen is best alternative.It can be produced domestically from fossil fuels such as coal, nuclear power etc. and thus reducing our dependence on fuel imports. It can be used in fuel cells to power electric motors or burned in internal combustion engines.It produces no air pollutants or greenhouse gases when used in fuel cells and only produces nitrogen oxides when burned in ICEs.

Did you hear about Stanly Allen Meyer's Patents ? He designed a Hydrogen on Demand System, that could power a Car just on Tap-Water.
Unfortunatly he died ( Was poisoned ? ) Just before he was able to mass-produce his Invention.
