This Monday, however, the Massachusetts Institute of Technology (MIT) announced the development of a new oxygen production catalyst that is 200 times more efficient than platinum. The nickel-borate-based catalyst has been licensed to Sun Catalytix - http://www.suncatalytix.com/, which is hoping to be producing safe, super-efficient electrolyzers within two years.

Stuart Island project
One such pilot program is operating on Stuart Island in Washington State. There the Stuart Island Energy Initiative[32] has built a complete, closed-loop system: Solar panels power an electrolyzer which makes hydrogen. The hydrogen is stored in a 500 gallon tank at 200 PSI, and runs a ReliOn fuel cell to provide full electric back-up to the off-the-grid residence.

Compressed air engine
Generating compressed air would be more economical and practical than making hydrogen using electrolysis. The metal plates will corrode away in a short while.
