Hydrogen Fundamentals

An introduction to hydrogen derivatives: e-fuels and ammonia

The route to decarbonisation and the energy transition has sometimes been described as de-fossilisation. Liquid fuels are incredibly useful energy vectors due to their high energy density and ease of handling. The challenge is to substitute these refined products that are derived from crude oil with sustainable, convenient and cost-effective alternatives. Liquid fuels of a non-fossil origin are one such solution. They can be produced using renewable electrical power to generate ‘e-fuels’ through Power-to-Liquid (PtL) technology.

Thousands of tonnes per year of CO2 (carbon dioxide) could be utilised in this way to build the required hydrocarbon molecules. At the same time, the narrative around green ammonia has crystallised in recent months and years – increasingly heralded as one of the most cost-effective ways of transporting green hydrogen over long distances as an energy vector. What unites both e-fuels and green ammonia is hydrogen. In this online training module, learn the fundamentals of how and why. With this two-hour masterclass, you can enhance your understanding of what exactly e-fuels are, how they are produced and what role they could have to play in the short and medium-term; learn more about the green ammonia concept that is so talked about and promoted; and get a firm grasp on the intersection between e-fuels, ammonia and hydrogen, rooted in both science and business case.
