What To Do About Global Warming

I'm starting to think that we're just never going to get away from fossil fuels any time soon, so maybe we should be thinking more about better ways to use them.

Within the past few years, enormous new petroleum reserves have been developed miles underground in the Gulf of Mexico (the BAHA oil field). The extreme depth of these reserves means that they are at very high temperature and pressure, which is a "problem". But what if this isn't a problem at all, but actually an advantage?

We all want hydrogen cars, don't we. (Yes.) But how do you make hydrogen? You process hydrocarbons using water and nickel (as a catalyst) at very high temperature and pressure.

Hmm. That's just what you have at the bottom of these new deep wells. Why not process the hydrocarbons into hydrogen deep underground? You also get ammonia, which is used to make fertilizer, and carbon dioxide, which will need to be left underground somehow.

What are your thoughts?
