I'm brand new here and this is my first post. I am a regular at out of Australia and I found this forum by following a link on the subject of methane production from pure hydrogen. I tried to put my 2-cents' worth in as a "reply" to a comment on this thread, but it wouldn't let me so here I am. That being said, here's my question:

How can I produce methane gas from pure hydrogen without using the Sabatier Reaction?

Let me give you a little background. On, most of us build windmills, myself included. The windmills produce electricity using several methods. I build three-phase alternators and rectify the current for use in charging batteries on the ground. To that end, there are times when the alternator puts out more than the batteries either want or can handle and the "excess" is diverted to what is called a "dump load" which is more often than not, merely a resistive load like a water heater. This saves the whole shebang from catching fire, etc.

What we'd like to be able to do is run the excess d.c (direct current) through a Brown's Gas generator (simple electro-mechanical device) to create hydrogen and oxygen from water. The oxygen is "scrubbed" off with iron filings--steel wool and what is left is almost pure hydrogen gas. We'd then like somehow to turn this elusive gas into methane, to be stored under a water column (most likely) and used as a method of storing excess electricity. The methane could be used for cooking or heating or as a weak motive fuel.

Any ideas?
