E-fuels, including e-methanol, are emerging as a solution in the energy transition by combining green hydrogen and captured CO2 to create synthetic fuels compatible with existing infrastructure. The EU and US have set mandates and incentives to drive e-fuel production, with a focus on road, aviation, and marine sectors. Corporate investments from companies like Infinium and HIF Global indicate growing confidence in the commercial viability of e-fuels. E-methanol leads the e-fuel landscape due to its versatility and mature production technologies, with a global project pipeline exceeding 15 million tonnes of annual capacity by 2030. While challenges like high production costs and infrastructure limitations exist, e-fuels are crucial for decarbonizing sectors like aviation and maritime transport. Overcoming these hurdles will be vital for the widespread adoption of e-fuels, which are poised to have a significant role in the global energy transition.
