Cames, Martin; et al. (2021): E-fuels versus DACCS. Total costs of electro-fuels and direct air capture and carbon storage while taking into account direct and upstream emissions and environmental risks

Cames, Martin; Chaudry, Saleem; Göckeler, Katharina; Kasten, Peter; Kurth, Stefan (2021): E-fuels versus DACCS. Total costs of electro-fuels and direct air capture and carbon storage while taking into account direct and upstream emissions and environmental risks. Study on behalf of Transport [&] Environment (T[&]E). Öko-Institut e.V. Berlin.

„For defossilizing European aviation, synthetic fuels or electro fuels (e-fuels) might play a pivotal role in the long term. The UK’s Committee on Climate Change, however, suggests that offsetting aviation’s emission from fossil kerosene through direct air capture and carbon storage (DACCS) is more cost effective than replacing fossil kerosene by e-fuels. In this study we estimate and compare the total costs of both options while considering direct and upstream emissions and the environmental risks of both options. The aim of this comparison is to identify the scope of the potential cost advantage of the DACCS route and to assess whether it involves risks or caveats in the longer term.“
