What are BtL fuels?

BtL stands for the English biomass to liquid (to German biomass liquefaction). BtL fuels are therefore to be understood as meaning synthetic fuels made from biomass. These fuels are not yet available on the market today, so the challenge is to adapt fuel production, which is already known from coal and natural gas, to biomass as a raw material.

Different biomass can serve as raw material. The range extends from residual materials such as straw and residual wood to energy crops. For plants grown specifically for fuel production, for example, a yield of around 4,000 l per hectare is expected. Estimates assume that they have the potential to replace 20-25% of German fuel requirements, and even more in Europe. With this capacity, BtL fuels can make a significant contribution to the substitution of finite fossil fuels.

In addition to the broad and more efficiently used range of raw materials, advantages are seen primarily in the fuel quality, which also meets the increased requirements of the automotive industry.

The generic term "XtL fuels" summarizes processes that produce synthetic fuels from e.g. coal (CtL: Coal to liquid), gas (GtL: Gas to liquid) or biomass (BtL: Biomass to liquid).

Definition of BTL fuel:

“Biomass to liquid” refers to a process chain that converts biomass into Synthesis gas and its subsequent synthesis converts to liquid hydrocarbons. The biogenic hydrocarbons produced in this way can be processed into marketable fuels such as diesel according to EN 590 or gasoline according to EN 228 using well-known petroleum refining processes.
