Infinium Begins Construction at Project Roadrunner eFuels Site in Texas

Pretty much everywhere you look, there’s a focus on decarbonizing the global economy, and a lot of those discussions start with the transportation sector. It generated 27% of U.S. greenhouse gas (GHG) emissions in 2020, putting it at the top of the list, just ahead of power generation and industrial production; combined, the three sectors account for more than three-quarters of the nation’s GHG emissions. For personal transportation, most of the attention has been on electric vehicles (EVs), but since the commercial transportation sector is largely powered by diesel and jet fuel, the push for decarbonization in trucking, air travel, and shipping has largely focused on ways to produce alternative fuels that reduce GHGs. Among those are ultra-low-carbon fuels called electrofuels, also referred to as eFuels, synthetic fuels, or Power-to-Liquids (PtL). In today’s RBN blog, we explain what eFuels are and how they compare to other alternatives, how they are produced, and what opportunity there might be to make a dent in the consumption of traditional transportation fuels.

As the push for decarbonization in the transportation sector gathers momentum, electrofuels — also known as eFuels, which are produced by using electricity to combine the hydrogen molecules from water with the carbon from carbon dioxide (CO2) — are beginning to attract attention as an alternative fuel with three important selling points in today’s environment. First, eFuels are available now and can be made with current technology, although there is a lot of room for future improvements and growth. Second, because they are considered drop-in replacements, they are essentially indistinguishable from the fossil-based conventional fuels in use today, which means they can be used without any changes to the existing energy infrastructure. Third, they can capitalize on a rapidly growing set of hydrogen and CO2 suppliers eager to secure a diversified set of offtakers. In today’s RBN blog, we look at HIF Global’s approach to eFuels production, its demonstration plant in Chile and its big plans for Texas and beyond.

Around the world, there’s a strong push to put aviation on a more sustainable footing and reduce the industry’s greenhouse gas (GHG) footprint. Increasing the production of sustainable aviation fuel (SAF) — a close cousin of renewable diesel (RD) — is key to this effort. But while the economic case for producing RD in the U.S. has been compelling for some time thanks to government subsidies, the returns on investment for producing SAF appear more dubious, despite a seemingly generous production tax credit for SAF in the Inflation Reduction Act (IRA). As we discuss in today’s RBN blog, the incentive for making jet fuel is likely too small — and too short-lived — to overcome the higher cost of production for SAF compared to RD, and additional incentives may be needed to spur meaningful increases in SAF production.
