Matthew Simmons died last week, and it's a loss to the peak oil advocacy network. It was only after his death that I started to peek around his website -- the Ocean Energy Institute -- where I noticed that he too shared a belief [PDF] that ammonia played a major role in the future of any carbon-free economy. Basically, Simmons advocated for massive construction of offshore wind on both coasts of the US and in the Great Lakes, as well as onshore wind in the midwest, all tied together with a major grid and with plug-in hybrids, and later ammonia fuel, as storage.
I first wrote about Ammonia about two years ago, and haven't seen anything to really change my mind since: if we need a liquid fuel that can be produced on a large scale and power both existing infrastructure (with modifications) and future projects, ammonia is definitely a winner. If anything, I've become more convinced of NH3's merits because the "reserve" of the key element--nitrogen--is enormous and omnipresent, while doing anything with carbon at this point other than burying it seems like madness.
