What surprised me was how convinced she was that hydrogen was an "energy source". But something I notice of course is that my students don't neccessarily realize that I am an expert on some things :)

But much research by supposed experts in energy and resource economics is nonsensical in physical terms. On the other hand a lot of natural scientists and engineers tend to underestimate the adaptability and resourcefulness of the economic system....

I am trying to cut a middle path but we tend to get assailed from both sides...

The most promising approach to carbon sequestration (apart from growing trees) seems to be pumping CO2 into old oil reservoirs. Of course that takes energy, but the oil forced out might help reduce costs. But most existing power stations are not in the right location, or getting coal to those locations would need a lot of new infrastructure. So probably would be a fairly limited application in the end?

The other technologies involve biological approaches to capturing carbon. One I saw written up recently sounded very expensive though for the amount of carbon being sequestered.

For the moment conservation, increased efficiency, substitution of nat gas for coal, and alternative energies as well as tree planting are all much more cost effective.
