12 Insights on Hydrogen

Abstract

Hydrogen has generated enormous hype over the past two years. Some twenty countries, collectively accounting for nearly half of global GDP, have already adopted hydrogen strategies, or intend to do so. On two previous occasions, rising interest in hydrogen fizzled out without lasting effect. Can we expect a different outcome this time around? The world is striving to achieve climate neutrality, and renewables have become the cheapest form of new generation across the globe. But not all applications lend themselves well to direct electrification. Green molecules have a role to play, but there are several unanswered questions: From which sources should they be obtained? How should they be stored and transported? And in which applications are they indispensable? In 12 Insights on Hydrogen, we sought to shed light on these uncertainties by offering a quantitative, evidence-based assessment that compiles the wealth of existing hydrogen research into one, internally consistent discussion.
