![]() ![]() While the EU Commission states in its 2020 Hydrogen strategy that “Renewable hydrogen is the most compatible option with the EU’s climate neutrality and zero pollution goal in the long term and the most coherent with an integrated energy system.”, it goes on to state that “In the short and medium term, however, other forms of low-carbon hydrogen are needed, primarily to rapidly reduce emissions from existing hydrogen production…” The EU is similarly anticipating significant use of blue hydrogen in the years to come. "We see no way that blue hydrogen can be considered 'green.So called “blue hydrogen”, made using fossil fuels and capturing and storing the associated greenhouse gas emissions, has long been touted as less expensive than renewable alternatives and necessary during a transition phase to a low carbon society. IRENA – the International Renewable Energy Agency, predicted earlier this month that a third of all hydrogen or 200 million tonnes used in 2050 will be blue. "Blue hydrogen has large climatic consequences," states the report. "We see no way that blue hydrogen can be considered 'green.'" I don't think we should be spending our funds this way, on these sort of false solutions."Ĭlimate advocates and progressives have slammed the $550 billion bipartisan infrastructure bill as woefully insufficient and the Congressional Progressive Caucus has asserted they won't support a bipartisan bill without a bold reconciliation bill that includes far stronger climate measures. "Blue hydrogen is a nice marketing term that the oil and gas industry is keen to push but it's far from carbon-free. "It's pretty striking, I was surprised at the results," said Howarth. Once the byproduct carbon dioxide and the other impurities are sequestered, it becomes blue hydrogen, according to the U.S. The process of producing blue hydrogen starts with converting methane to hydrogen and carbon dioxide by using heat, steam, and pressure, or gray hydrogen, but goes further to capture some of the carbon dioxide. Robert Howarth, the scientist at Cornell University who co-authored the paper "How Green is Blue Hydrogen?," alongside Mark Jacobson, a Stanford University researcher, said: "The best hydrogen, the green hydrogen derived from electrolysis-if used wisely and efficiently-can be that path to a sustainable future. Green hydrogen is achieved when water goes through electrolysis (with electricity supplied by solar, wind, or hydroelectric power) and the water is separated into hydrogen and oxygen. The fossil fuel industry has enthusiastically pushed for blue hydrogen as a clean energy source, but the scientists warn that this product is not the same as the "gray hydrogen"-derived from methane production-or the "green hydrogen" commonly viewed as an important fuel for future energy transition.Īccording to a statement from the researchers:Īn ecologically friendly "green" hydrogen does exist, but it remains a small sector and it has not been commercially realized. The White House claims that the bill is in step with President Joe Biden's climate goals and advocates of hydrogen energy champion it as a low-emissions alternative for various uses such as fuel shipping, trucking, aviation, and heating.īut new research published in the journal Energy Science & Engineering finds that the carbon footprint to create blue hydrogen is more than 20% greater than using either natural gas or coal directly for heat, or about 60% greater than using diesel oil for heat. I don't think we should be spending our funds this way, on these sort of false solutions." The $550 billion bipartisan infrastructure package passed Tuesday includes $8 billion to develop "clean hydrogen" via the creation of four regional hubs. Senate this week includes billions of dollars of funding toward "blue hydrogen," which new research published Thursday finds is more polluting than coal. While celebrated as a climate victory by the Biden administration, the large infrastructure bill passed in the U.S. ![]()
