Hydrogen Economy Rising Again | Climate Denial Crock of the Week
Large-scale adoption of hydrogen could also fuel an increase in demand for renewable power generation, IRENA’s report finds. In total, IRENA sees a global economic potential for 19 exajoule (EJ) of hydrogen from renewable electricity in total final energy consumption by 2050. This translates into around 4-16 terawatts (TW) of solar and wind generation capacity to be deployed to produce renewable hydrogen and hydrogen-based products in 2050.
However, deployment of hydrogen-based solutions will not happen overnight, IRENA’s report cautions. Hydrogen might likely trail other strategies such as electrification of end-use sectors, and its use will target specific applications. The need for a dedicated new supply infrastructure may also limit hydrogen use to certain countries that decide to follow this strategy. Existing natural gas pipelines could be refurbished, but implications must be further explored.
Rocky Mountain Institute:
Hydrogen is the new kid on the block of low-carbon alternatives, with applications in mobility, industrial processing, and heavy transport. It can also be used to provide electricity and heat, and can be blended with natural gas to help decarbonize existing natural gas grids. But even with these opportunities, across the globe—from corporate offices to industry roadshows—one hears a frequent refrain: it is too expensive and it won’t scale. (Interestingly enough, this is the same reputation solar PV had a decade ago.)
As misconceptions about hydrogen abound, there is an opportunity to dispel
