I thought the Austin report was about generating electricity from coal-fired and natural gas turbine plants to charge battery vehicles. I don't recall the report addressing hydrogen production. Most hydrogen is created from natural gas, a process that also consumes water, but in the US more than 50% of hydrogen created from natural gas goes into gasoline. Why not use that hydrogen in a fuel cell and get better mileage and a cleaner car while researchers keep working on hydrogen from industrial waste, biomass, algea and sewage?<div class="comment-remix-meta"><a href="#" class="replyto" onclick="replyto('1441','Liz'); return false;">Reply</a> - <a href="#" class="quote" onclick="quote('1441','Liz','Did I miss something?

Water coming off a fuel cell is essentially free of contaminates. Hydrogen "burned" yields water back to the atmosphere. Water needed depends entirely on how you're making Hydrogen, if it's electroylsis then you need a butt ton of it. If it's thru some bacterial formation, then you can probably use gray water. it's not an insurmountable problem, unless the only source of hydrogen is electrolysis. There is some early research on using nanotubes to desalinate water that looks very promising. and running that thru a fuel cell before you drink it might not be a bad idea..<div class="comment-remix-meta"><a href="#" class="replyto" onclick="replyto('1414','james jones md, phd'); return false;">Reply</a> - <a href="#" class="quote" onclick="quote('1414','james jones md, phd','1st the water can be recycled.

Once the electricity is created additional water is needed for the electrolyser to break the water into hydrogen and oxygen. That amount is approximately 54 pounds per 1,000 cubic feet of H2.
