Powering Your House with Hydrogen?

As suggested here, there is no law that says you can’t power your house with electricity derived from hydrogen fuel cells. Of course, that doesn’t make it a good idea.

The problem is that the processes of electrolyzing water, then running the resulting hydrogen through a fuel cell, results in a net energy loss of approximately 50%.  So if you want if you don’t mind dealing with something is so horribly inefficient that it requires twice as much energy to get the same job done, then maybe hydrogen isn’t a bad solution.

Even if that isn’t a deal-breaker, the fabulous capital and operational costs associated with the whole thing should be.

If hydrogen has a role in our energy future, it lies in transportation, where a portable liquid fuel is a potential competitor to batteries and petroleum derivatives.
