HYGS Hydrogenics (NASD:HYGS) is a commercial stage company that develops and sells electrolyzers for hydrogen generation. This is often integrated with hydrogen storage and PEM fuel cells, as well as hydrogen fueling stations. It sells into both stationary power and vehicular markets. HyperSolar, Inc (OTC:HYSR). Hypersolar is a very early stage developer of a solar powered system to directly use solar power to produce hydrogen from water. While cutting out the extra step of converting sunlight to electricity with photovoltaics before using electrolysis to split hydrogen from water may sound attractive, the company is at an extremely early development stage and does not have sufficient funding to advance its technology. It's also not clear if the technology is more efficient at converting sunlight to hydrogen than the combination of photovoltaics and electrolyzers would be, or what the capital costs are. I can't imagine any scenario where a long term stock market investor could make a profit on HyperSolar. http://www.google.com/finance?q=hysr&ei=0unJUvicE8GBiwKRpQE
