Hydrogen inclusions are a big problem in welding. But it's a well known issue.

At least to the point where fuel cell cars are about to sold in showrooms en mass. If the issues get ironed out over the next decade then fuel cell vehicles will become a major sector in transportation.

A great post with lots of good links (edit-delete unrelated stuff)

Twenty Hydrogen Myths by noted environmentalist Amory Lovins

Amory Bloch Lovins (born November 13, 1947)[3] is an American physicist, environmental scientist, writer, and Chairman/Chief Scientist of the Rocky Mountain Institute. He has worked in the field of energy policy and related areas for four decades. He was named by Time magazine one of the World's 100 most influential people in 2009.

PUBLISHER: Rocky Mountain Institute

Twenty Hydrogen Myths:

Myth #1. A whole hydrogen industry would need to be developed from scratch.

Myth #2. Hydrogen is too dangerous, explosive, or “volatile” for common use as a fuel.

Myth #3. Making hydrogen uses more energy than it yields, so it’s prohibitively inefficient

Myth #4. Delivering hydrogen to users would consume most of the energy it contains

Myth #5. Hydrogen can’t be distributed in existing pipelines, requiring costly new ones

Myth #6. We don’t have practical ways to run cars on gaseous hydrogen, so cars must continue to use liquid fuels

Myth #7. We lack a safe and affordable way to store hydrogen in cars

Myth #8. Compressing hydrogen for automotive storage tanks takes too much energy

Myth #9. Hydrogen is too expensive to compete with gasoline.

Myth #10. We’d need to lace the country with ubiquitous hydrogen production, distribution,and delivery infrastructure before we could sell the first hydrogen car, but that’s impractical and far too costly — probably hundreds of billions of dollars

Myth #11. Manufacturing enough hydrogen to run a car fleet is a gargantuan and hugely expensive task.

Myth #12. Since renewables are currently too costly, hydrogen would have to be made from fossil fuels or nuclear energy.

Myth #13. Incumbent industries (e.g., oil and car companies) actually oppose hydrogen as a competitive threat, so their hydrogen development efforts are mere window-dressing.

Myth #14. A large-scale hydrogen economy would harm the Earth’s climate, water balance, or atmospheric chemistry

Myth #15. There are more attractive ways to provide sustainable mobility than adopting hydrogen.

Myth #16. Because the U.S. car fleet takes roughly 14 years to turn over, little can be done to change car technology in the short term

Myth #17. A viable hydrogen transition would take 30–50 years or more to complete, and hardly anything worthwhile could be done sooner than 20 years

Myth #18. The hydrogen transition requires a big (say, $100–300 billion) Federal crash program, on the lines of the Apollo Program or the Manhattan Project

Myth #19. A crash program to switch to hydrogen is the only realistic way to get off oil.

Myth #20. The Bush Administration’s hydrogen program is just a smokescreen to stall adoption of the hybrid-electric and other efficient car designs available now, and wraps fossil and nuclear energy in a green disguise.
