Also off topic; mods - perhaps OT posts can be split?
Its made from other energy sources, such as fossil fuel, because it takes as much energy to make hydrogen as you get out of it. Most of it today is made from natural gas and coal, and the processes that make it pollute, and its the really the fossil fuel and nuclear industries and some chronies in the government that are advocating a hydrogen as an energy "source", not scientists.
Sure H2 doesn't contain C- C bonds, but bond formation can also produce energy - in this case the same energy required to produce the H2, so yes,
effectively it is an energy storage medium.
As for non-fossil based H2 production: perhaps you should look at some developments of recent times, such as; biological production of hydrogen - still in it's infancy, but shows great promise - and solar production of hydrogen for which efficiency is relatively high at ~8% conversion, and bound to be improved further. Fuel cell technology continues to advance, particularly now that major auto companies are playing a bigger part. Check out the CRC handbook on Fuel Cell Technology to see just how much research has gone into developing efficient and practical cells over the past 10 years.
I don't see many fossil fuels in this picture
Add a few of the newer SOFC fuels cells, and b/u
sunballs & batteries, you're well on the way to being completely self sufficient.
I agree, but lets actually learn the science, instead of allowing our selves to be fooled by snake oil salesmen and other profiteers
I certainly don't claim to have all the answers. I only boast a recent degree in applied chemistry (started and completed while in my 40's) and 20 years working as a self employed (qualified) electronics technician/ designer. However, I do much of our group's research in my own lab, which at present contains among other things, a nearly completed pilot plant methane producing digester which will double as a fertilizer producer *, experimental H2 production equipment, and a pile of recently acquired QVF glass - to be used to expand our current research into energy efficient biodiesel production from enzymatic/ catalytic processes.
So, from my own extensive research over the past 5 years or so, I don't believe for a minute that the concept of a H2 based economy is simply a lie fostered and spread by snake oil salesmen.
Just because a scientist is involved with, or represents a company, it doesn't mean he doesn't still see things from a logical and realistic perspective. Sure there's money to be made, but there's also a planet to save and a global economy to even out (my words here). Hydrogen has a major part to play here IMO, as apart from initial costs in outlay, H2 will soon be able to be produced onsite in a cost effective manner that doesn't have on any ongoing reliance on fossil fuels.
If you have a fast connection, you might want to look at this presentation by David Freeman.
