DeepSummary
The episode features a conversation with Meg Gentle, the executive director of HIF Global, an e-fuel company. Meg explains what e-fuels are and how they can be used as a carbon-neutral alternative to fossil fuels in industries like shipping and aviation. She discusses the production process, which involves combining hydrogen from water electrolysis with captured carbon dioxide to create a synthetic liquid fuel.
Meg provides details on two major HIF Global projects: a plant in southern Chile that produces shipping fuel and gasoline using wind power, and a larger $7 billion facility planned for Texas that will produce e-methanol for shipping using a combination of wind and solar energy. She highlights the challenges of scaling up e-fuel production, including costs and the need for supportive policies and tax incentives.
Meg emphasizes the importance of clear market signals and regulations to incentivize investment in e-fuels. She believes the technology has significant potential, especially for sectors like aviation with limited decarbonization options, but acknowledges that costs must come down through manufacturing improvements and economies of scale. The conversation also touches on research efforts in the field.
Key Episodes Takeaways
- E-fuels are synthetic liquid fuels made by combining hydrogen from water electrolysis with captured carbon dioxide, offering a potentially carbon-neutral alternative to fossil fuels.
- E-fuels have significant potential for decarbonizing hard-to-abate sectors like shipping and aviation that rely on energy-dense liquid fuels.
- The production of e-fuels is currently more expensive than fossil fuels, but the costs are expected to come down through manufacturing improvements, economies of scale, and assigning value to carbon reduction.
- Clear market signals, such as mandates or incentives, are crucial for attracting the large investments needed to scale up e-fuel production facilities.
- Supportive policies and regulations, including tax credits for hydrogen production and carbon capture, can help make e-fuels cost-competitive with conventional fuels.
- Major e-fuel projects are underway, such as HIF Global's plant in Chile using wind power and a planned $7 billion Texas facility combining wind and solar energy.
- Research and development efforts are ongoing to improve e-fuel production technologies and bring down costs further.
- While e-fuels release CO2 when burned, the CO2 is captured from existing sources, potentially making the lifecycle emissions lower than fossil fuels.

Cleaner alternatives to the oil and gas that power vital industries are necessary for economy-wide decarbonization. E-fuels, or electrofuels, are touted as a carbon neutral solution for the hard-to-decarbonize sectors that rely on energy dense fossil fuels.
E-fuels are made by combining hydrogen with carbon dioxide. Through the electrolysis process, water is split into oxygen and hydrogen atoms. The hydrogen is then combined with CO2 through a process called synthesis. The outcome is an energy-dense liquid, synthetic fuel.
But currently, the e-fuels production process makes these alternatives more expensive than fossil fuels. And when burned, they release CO2, making critics question the claims of climate neutrality.
So, what is the climate impact of e-fuels? What industries are turning to these alternatives for decarbonization? And how can policy and tax incentives make them cost competitive with conventional oil and gas?
This week host Bill Loveless talks with Meg Gentle about the use of e-fuels for transport.
Meg is the executive director of HIF Global, an e-fuel company developing some of the largest projects around the world. Before joining HIF, Meg served as the director of Ovintiv, an independent petroleum company, and as the president and CEO of the natural gas company Tellurian. She also spent ten years working for Cheniere Energy, helping grow their LNG marketing and trading company into a world-wide business.
