Synthetic fuels aka 'power-to-liquid' fuels contain all liquid non plant based varieties.

Biofuels contain all fuels based on harvested plants.

Used oil refers to all oils that are produced for other industries and recycled as fuel.

If multiple types of fuels are still competing by close date, this will resolve to best available estimates of percentage used in commercial flight.

Some labs are working on hydrogenating biomass, extracting certain components, and mixing these with synthetic hydrocarbons. I think this approach is likely to be successful. Which category does it fall under?

Shouldn't this be a linked market that forces the total to sum to 100%? Not sure whether that can be changed after question creation though.
