Prices for hydrogen produced with clean energy will remain high, Harvard researchers demonstrate in the journal Joule, but the fuel may remain the only way to decarbonize some sectors.<\/p>\n\n\n\n

Green hydrogen is often touted as the solution for our toughest decarbonization problems: heavy industry, transportation, energy storage. The price will fall as production increases, goes the thinking, and this carbon-free fuel \u2014 made by splitting water molecules using renewable energy \u2014 will displace fossil fuels.<\/p>\n\n\n\n

But a study published in Joule<\/a> on Oct. 8 by Harvard University researchers shows that most estimates overlook the significant storage and distribution costs needed to deliver green hydrogen to different sectors \u2014 or how these costs vary across end-uses.<\/p>\n\n\n\n

With straightforward calculations, the authors show that at current and projected delivered costs, green hydrogen is a prohibitively expensive strategy to reduce emissions, often exceeding the costs of directly removing CO2<\/sub> from the atmosphere.<\/p>\n\n\n\n

\u201cEven if production costs decrease in line with predictions, storage and distribution costs will prevent hydrogen being cost-competitive in many sectors,\u201d said lead author Roxana Shafiee, a postdoctoral fellow at the Harvard University Center for the Environment. \u201cOur results challenge a growing idea that hydrogen will be the \u2018Swiss army knife of decarbonization\u2019 and suggest that the opportunities for hydrogen may be narrower than previously thought.\u201d<\/p>\n\n\n\n

Determining the carbon-abatement costs (USD per ton of CO2<\/sub> abated) of using green hydrogen across different sectors of the U.S. economy, the authors demonstrate the need for continued investment in other decarbonization strategies at earlier stages of development, as well as innovation in hydrogen storage and distribution technologies.<\/p>\n\n\n\n

\u201cThis does not mean that hydrogen won\u2019t play a role in a low-carbon energy future,\u201d said co-author Daniel Schrag, Sturgis Hooper Professor of Geology and Professor of Public Policy at Harvard. \u201cThere are logistical and economic challenges with every possible solution \u2014 including biofuels and electrification. But at this early stage of decarbonization, it is important that we invest in a broad range of strategies, and not bet our future on a single approach that remains very, very expensive.\u201d<\/p>\n\n\n
