Our hydrogen-electricity future: with strategies for getting there

We\´ll start by giving two answers to a single question, "Why Hydrogen?" We\´ll follow this with a brief discussion of the energy system architecture\´s five-link chain, to emphasize the key role of the central link, energy currencies. Then, gluing these two concepts together - (a) systemic architecture and (b) the answer to why hydrogen - we can set out the rationale leading to the premise that our system will ultimately be dominated by the twin currencies, hydrogen and electricity. All this will serve as a foundation for considering the sources, infrastructures and service technologies likely to characterize the deeper future (2100 ∼ 2200). Finally, based on this long view (and our sliver of time within it) we can use the perspective to suggest near-term strategies.
