Hydrogen could possibly be used for practically every little thing. It in all probability shouldn’t be.


Past that, although, hydrogen will in all probability be most helpful in industries the place there aren’t different sensible choices already on the desk. 

That’s a central concept behind an infographic I take into consideration lots: the Hydrogen Ladder, conceptualized and up to date incessantly by Michael Liebreich, founding father of BloombergNEF. On this graphic, he mainly ranks nearly each use of hydrogen, from “unavoidable” makes use of on the prime to “uncompetitive” ones on the backside. His metrics embrace price, comfort, and economics. 

On the prime of this ladder are current makes use of and industries the place there’s no different to hydrogen. There, Liebrich agrees with most consultants I’ve spoken with about hydrogen. 

On the subsequent few rungs come sectors the place there’s nonetheless no dominant technical resolution for cleansing up emissions, like delivery, aviation, and metal manufacturing. You may acknowledge these as famously “onerous to resolve” sectors. 

Heavy trade typically requires excessive temperatures, which have traditionally been costly to realize with electrical energy. Value and technical challenges have pushed corporations to discover utilizing hydrogen in processes like steelmaking. For delivery and aviation, there are strict limitations on the mass and measurement of the fueling system, and batteries can’t make the lower simply but, leaving hydrogen a possible opening.
