What is the role of direct air capture in sustainable aviation?

E4tech was commissioned by Transport & Environment (T&E) to assess whether, when and how direct air capture (DAC) could be scaled up to make e-kerosene at the scale needed to decarbonise European aviation. Decarbonising aviation will require significant ramp up of sustainable aviation fuels, including e-kerosene, a fuel produced by combining renewable hydrogen with carbon dioxide (CO2). T&E wanted to know how feasible it would be to do this using CO2 captured from the air, through DAC. This is particularly timely, as the European Commission is preparing to launch Refuel EU aviation, an initiative to boost supply and demand for sustainable aviation fuels in the EU, which is expected to include a target for use of e-kerosene.

What could the European cellulosic ethanol industry achieve by 2030?

The cellulosic ethanol industry is at a critical development stage; there are technology developers who are taking stock of the lessons learnt during the development of their first plants, and several more are constructing or planning their first plant. E4tech has undertaken a study on behalf of the European cellulosic ethanol industry to understand the deployment potential of the technology in the coming decade. This is important to determine the impact the industry can have on renewable energy use in the transport sector and its decarbonisation to 2030 and beyond.
