"We have some good ideas to develop stable photoanodes with better performance than titanium oxide,"

How many times have we seen this result in palladium catalysts, rare earth oxides, or gold nanoparticles.
Hint: Nature does it with just Magnesium and aromatic rings.

Molecular Hydrogen is not the future of transportation fuel. It will be a very necessary industry gas and used to build hydrocarbon fuels that will "drop in" to our current multitrillion dollar infrastructure. A lot of people jobs rely on that infrastructure... manufacturing, mechanics, chemists, etc. To replace it with molecular hydrogen would render millions of people obsolete.

To replace it with molecular hydrogen would mean millions of people would have to find a cleaner job

Poor souls, boo hoo, my heart bleeds, the agony, I can't bear it.

A question... do we have fuel cells that can use methane and other hydrocarbons instead of molecular hydrogen? And I mean reliable fuel cells that do not get get bogged down by carbon deposited on the catalysts.

Ok, so some people don't understand the difference between hydrocarbon as an energy carrier vs fossil fuels from the ground. A hydrocarbon built from solar energy (crops, micro organisms, or solar-chemistry) is just as carbon neutral as molecular hydrogen.

Wow, that is crass, a misquote, and inaccurate all it one! With that kind of jinx karma I'd be careful with your career path.

If you thought two steps ahead, you might recognize how many jobs would go overseas to economies that are far less efficient and more polluting than if we had kept them in the USA.

Of course another explanation is your a mouth piece for one of those countries hoping we will shoot ourselves in the foot and export millions of more jobs. I suspect though the trend of outsourcing is in decline. Boo hoo.

When you said this I pretty much switched off.

So which one is it then? Are businesses going to to repeat their mistakes or learn from them, I like to think the latter.
