Blue gas, i.e. hydrogen fuel cells: en.wikipedia.org Not clear yet (to me) what metals will be preferred. Could be good old zinc.

The color of the definition of hydrogen refers to its origin and how it is produced. Clean hydrogen is H2 irrelevant to the color definition green is derived from renewable energy in the 1980this Ballard used platinum as a catalyst for the H2+O reaction to generate electricity, heat and water vapor Today majority of fuel cells do not use platinum as catalyst. One example is nickel and Bucky-balls or MWCNT's or, ordinary rust (not exactly) of iron Fe is also a catalyst, various rare earth alloys are also catalyst at more elevated temperature and the newest certain MOF's - a combination of metal and organic molecules membranes induce bidirectional reactions. Next week I will know if I will join a team of scientists (half my age) which upon my initiative will work on related issues in conjunction with several US DOE national labs - cross fingers before they will learn of my young age and "drop dead".<GGGG> no joke, was in similar situation - head of dept. wanted me -young PhD "to be" opposed it -that's human nature hydrogen extraction and fuel cells are a moving target, lots of R&D and new development almost every 7-10 days for a more efficient or cheaper mouse trap

Some times I also give "kudos" where they belong. China is hard working on new technologies that will also generate "yelow" hydrogen. In certain places they have facilities working for few years and are on the right road to success even that I hope we will outsmart them. <ggg> but may be we think alike and therefore there is "TEKO" From a technological point of view of what is happening in China, Japan, S. Korea, UK, Russia and even Romania, I do think that the road toward a hydrogen economy is wide open with no need of platinum or paladium. On the other hand berylium (rare) nickel, chromium molybdenium,niobium tantalum, hafnium, tungsten etc., will be in high demand in addition to the rare earth metals, as the world is in transition to clean energy and away from hydrocarbons. en.wikipedia.org

TJ, hydrogen is best obtained from methane. Methane is 80% hydrogen. The other 20% is carbon. When methane is oxidized using air, the result is water which is great for irrigation and CO2 which is essential for crops. There's no need to separate the hydrogen. Where the hydrogen people go wrong is thinking that increasing CO2 from the tragedy of the commons level of 280 parts per million to 500 parts per million is a problem. Earth has never been in balance. It was dying because chlorophyll doesn't have an off switch. Plants proliferated and reduced CO2 from 8000 parts per million to starvation tragedy of commons 280 ppm. The ice age ensued. Simplistic so-called "scientists" made simplistic computer models of climate that told them that Earth was going to get too hot. Immediately, reality showed that the models were laughably faulty. The climate "scientists" were running a tree ring circus and tormenting data to keep the crowds entertained, scared, and paying $billions. PETA should expand to PETAD = people for ethical treatment of animals and data. . Nature has been destroying the ecosphere since the carboniferous time, burying the carbon in coal, limestone, tars, oil, gas, peat, methane hydrates and in kilometres of ocean floor sediment. Over millions of years the ocean sediment is carried along to subduction zones where some of it fuels volcanoes and much forms new oil and gas deposits or leaks back to the surface where it is recycled. That's how the world works = brief but essential details. At $40 per barrel, hydrocarbons are the way to go. In some areas photovoltaics are getting competitive. New designs of nuclear reactors are getting good too. Separating hydrogen is a bad idea. Better to recharge batteries or capacitors with the electricity from photovoltaics or use it directly. Mqurice
