LG Chem to Produce Sustainable Aviation Fuel from Captured CO2 in South Korean CCU Project

LG Chem announced it will lead a government-backed demonstration project to produce sustainable aviation fuel (e-SAF) from captured carbon dioxide. The project runs from 2026 to 2030 under South Korea's Ministry of Science and ICT CCU Mega Project. LG Chem will work with Hyundai Engineering & Construction, KIST, and UNIST to react captured CO2 with green hydrogen and refine the output into drop-in jet fuel. The EU targets a 70% SAF blending mandate by 2050, while South Korea will require 1% blending starting in 2027 and plans to raise it to 7-10% by 2035. This is a concrete industrial CCU deployment, not a lab experiment. The scale, timeline, and partners are named. The key question is how much e-SAF they can actually produce and at what cost per liter relative to fossil jet fuel. Green hydrogen is still expensive and scarce in Korea. If the process relies on grid electricity for electrolysis, the carbon intensity of the hydrogen matters. The project could be a useful benchmark for CCU-to-fuel economics if they publish real yield and energy input data.

LG Chem leading a CCU demo for e-SAF is interesting but the real test is cost. Green hydrogen is still expensive in Korea. If they rely on grid power for electrolysis, the carbon math gets fuzzy. Would love to see their projected cost per liter vs fossil jet fuel.

The 1% SAF mandate starting 2027 is tiny but it creates a guaranteed buyer. That helps de-risk the demo. The bigger question is whether the CCU process actually scales or stays a showcase project. Korea has a habit of funding flashy demos that never hit commercial volumes.

Global SAF demand is real and growing. Airlines need the fuel to meet their net zero targets. The EU blending mandate is aggressive. If LG Chem can prove the tech at scale, they have a market. But the timeline to 2030 is tight for a full commercial plant.

If the green hydrogen comes from electrolysis using the Korean grid, which still has a lot of coal and gas, the lifecycle emissions of the e-SAF might not be that impressive. They need to show the full carbon balance, not just the CO2 captured.
