$this->bbcode_second_pass_quote('aahala', 'T')he three physical forms of fuels are liquid, solid and gas.
There are many forms of energy, including ways to store it and ways to transport it. For example, one can use water to store energy, using two reservoirs with a significant height difference and a pump/generator system to convert between electrical energy and gravitational energy.
I would love to see a map that includes the top 20 or so forms of energy used by people and the various processes that can convert from one to another. I would like to see the efficiencies of these processes... energy efficiencies primarily, but there are probably material wastes involved as well.
For example, there are processes to convert coal to liquid hydrocarbon fuel and also from natural gas to liquid hydrocarbon fuel. I expect that if electricity were free, one could somehow extract carbon dioxide from the air and split out the carbon, take water and split out the hydrogen, combine the carbon and hydrogen and end up with liquid hydrocarbon fuel. How efficiently could this be done? If electricity were free, it would probably be cost effective!
So one question is, what are the best known technological pathways for converting energy in one form to energy in some other form.
The more immediate question is: given the current industrial capacity, the actual installed and running machinery we have, and the various end users of energy and the form these end users require today, and the costs for retiring existing equipment and building new equipment.... how can we best get energy to the most important customers over the next few years, and how can we start encouraging investment in the converson pathways and end use equipment that will best match the future availability of various forms of energy with the most important end uses.
