Hydrogen era no longer a distant mirage


For decades oil producers have stored fossil fuels in manmade caverns carved into naturally occurring salt domes, deep below the surface of the U.S. Gulf Coast. Now, this hydrogen infrastructure will form the center of several marquee initiatives launched in 2020 to unlock the much broader potential of the most abundant element in the universe. To learn more, read “Hydrogen era no longer a distant mirage.”

Key Takeaways

  • Hydrogen will power fuel cells to drive passenger vehicles, heavy-duty trucks, ships, airplanes, as well as heat and light buildings. It will enable levels of decarbonization unimaginable using only renewable resources and battery storage.
  • With limited demand and no real scale to date, green hydrogen sourced from renewable energy can cost four times as much as other options, according to the International Energy Agency.
  • “A truly hydrogen-based economy … appears out of reach, at least before 2030,” S&P Global Ratings said in a report released in November. “Energy transitions typically take decades.”

Path to 100% Perspective

Green hydrogen makes up less than 0.1% of the world’s 70 million-metric-ton annual hydrogen supply, according to the Green Hydrogen Coalition, a California-based nonprofit advocacy group. “Gray” hydrogen, produced from natural gas using high-temperature steam methane reforming, and “brown” hydrogen, made by gasifying coal, account for almost all hydrogen in use today. The chief customers are oil refineries, chemical plants and industrial manufacturers such as steel and cement makers. “Blue hydrogen,” a lower-carbon variant, also uses fossil fuels as a source but offsets emissions with carbon capture and storage. Blue and green hydrogen are not widely used at this time.
