RE: Transport of Energy

Hey Mike
. . . sorry for the long delay . . . it's been a crazy (good) week. What claims did I make about Hydrogen that you would like some data on? Let me know and I'll send stats your way. I also see your point about my note. Clarification: The capital cost to construct a system to capture solar energy is expensive. However, once it is built, the solar energy does not cost you anything (at the margin) to capture. Sunlight that you do not capture and use (or store) is lost forever. Now . . . you could also make this argument about oil too . . . once the well is constructed the actual marginal cost of the oil out of the well is close to $0. The difference however is that the oil will run out from the well which means you have exploration costs to find other resources and the oil you extract actually has imputed costs associated with it.
Hope this helps.

Tess . . .
the only way to transport solar, wind and geothermal energy around is to first turn it into electricity and then send it through the standard electrical grid for immediate consumption. Unfortunately most wind resources are most abundant in areas remote from existing electricity grids, solar is expensive and both are intermittent. Geothermal on the other hand can be mined and used at source in many different applications . . . but will seldom generate the entire energy that you need at different and varying points in time. Notwithstanding all this, Hydrogen is an excellent Electrical storage medium that can be used to effectively move solar and wind around, along with stabilizing it. There are a few companies (ours included) that are at various stages of developing technology that will facilitate this. We'll be ready to help you in Australia and other areas of the world in 2011. Stay tuned . . . the climate change / oil shortage solution has already been developed . . . its just taking a while to get it to market. Fuel Cells have held us up, but now that Hydrogen Internal Combustion Engines and Turbines operate at efficiency levels that rival fuel cells and Hydrogen Gas Storage technology is available safely and cost effectively at 10,000 psi, the barriers to Hydrogen becoming a major part of our energy structure have been removed. The only drawback is the round trip energy conversion ratio, which is 25%. However, given that wind and solar energy is free and completely limitless once you have the ability to capture it, 25% is much more substantial than 0%. If you want to stay tuned on our developments go to www.h2green.com in June of this year and you'll be able to track (and participate in) our development if you like.
Hope this was helpful.
Jim
