Building a Hydrogen Economy

Policymakers worldwide are advocating a move to energy sources that don't rely on fossil fuels. Could hydrogen be the answer — or at least part of the answer? In this hour, we'll talk about moving toward a hydrogen economy — the technological developments necessary to make it a reality, how long such a shift would take, and whether a move to hydrogen would truly free us from a dependence on fossil fuels.
