Switching to H_2

摘要

The debate on hydrogen will continue, but it need not preclude broad cooperation to develop sustainable energy technologies that serve multiple agendas. The emergence of climate change represents a compelling call to undertake collaborative efforts. Avoiding catastrophic impacts on the global atmosphere will require immense quantities of carbon-free energy. The difficulties of supplying sufficient amounts will only intensify with rising populations and standards of living. This is the essential context in which the future roles of hydrogen and electricity must be explored if humanity is to meet the critical challenges facing it this century.
