Renewable energy, electrification, and battery storage are primary solutions. However, some sectors remain difficult to decarbonize using such methods, including heavy industry, heating, and certain transport sectors, such as aviation and shipping. The most prevalent is steam methane reforming (SMR). CLICK TO ENLARGE.

That’s seen as especially valuable for cleaning up aviation , maritime shipping, and heavy industries like steel that are more difficult to run on renewable energy and batteries. The alternative to electrolysis is a process called steam-methane reforming.

It’s packed with energy; per unit of weight, at least 60 times as much as the lithium-ion batteries used to propel electric cars. In the presence of the sun’s rays, nitrogen molecules set of a chain of reactions that produce ozone and destroy free-floating atmospheric methane. It’s also terrible for the climate. Others warm it.

Hydrogen opponents cite its inefficiency relative to batteries, and question the wisdom of building a complex and costly new infrastructure. Hydrogen fuel cells are controversial—several automakers, including Daimler , Honda , GM and Volkswagen , have abandoned the technology, while Toyota continues to pursue it.

Other technologies are in the mix, such as battery electric vehicles. Meanwhile, there are applications with few low-carbon options that need the biomass more, such as biofuels for aviation," said Meera Atreya, Energy Transitions Commission Bioeconomy lead. There are other ways to make hydrogen.

In 2022, aviation accounted for 2% of global CO2 emissions. The captured CO2 is then converted into methane (CO) and blended with the hydrogen, most commonly using a technology called Reverse Water Gas Shift (RWGS), to produce syngas. But all this travel comes at a steep carbon cost.

It’s also easy to store on board and, unlike batteries or tanks of hydrogen, it doesn’t take away too much space from the cargo hold. The colorless liquid can be used as a “drop-in” replacement for oil-based fuels with relatively minor modifications to a ship’s engine and fuel system. Methanol, or CH?OH,
