By capturing carbon dioxide from combined heating and power (CHP) plants and add hydrogen gas, it is possible to create aviation fuel with 86 % less carbon dioxide emissions than with fossil fuels. Except for the environmental gains, the fuel is also cost-competitive.

In a joint project, IVL Swedish Environmental Research Institute, energy company Jämtkraft, Chalmers University of Technology and Lund University have looked at the preconditions to start a big-scale production of renewable aviation fuel, so-called biojet, in Sweden. The project has been looking at capturing carbon dioxide from Jämtkraft’s CHP plant in Östersund, in the north of Sweden. The captured carbon dioxide is mixed with hydrogen gas produced with renewable electricity, which is used to produce elctrofuel that can be used in the existing aeroplanes.

When finalised, the facility in Östersund can produce 80,000 tonnes of electrofuel, out of which about 27,000 tonnes become finished biofuel. That is about 5 % of the aviation fuel used in a year in Sweden. The cost to produce the fuel is expected to be about 15-25 SEK (€1.49-2.48) per litre.

The results from this study are based on the production facility in Östersund and will vary depending on factors such as the raw material and electricity source available at the location.
