4. Biofuels

Jun 12, 2020

In an effort to reduce CO2 emmision, transport has become the most resilient sector due to its strong dependence on fossil energy sources. Oil, being the main energy source for transport, supplies 95% of the sector´s energy consumption and it is expected to reach depletion by 2050; currently, there is an objective to reduce the CO2 emissions in 80-95%. Therefore, substitution of oil needs to start as soon as possible to compensate for the declining oil production. The ultimate solution to near full decarbonisation of transport is the substitution of fossil sources by CO2-neutral alternative feedstocks. Transport fuels from renewable sources should be given particular attention, as they can be produced from a wide variety of primary energy sources, such as biomass. Biomass is considered to be carbon neutral because the quantity of CO2 released during combustion is the same as that absorbed by the plant during photosynthesis. Production of transport fuels from lignocellulosic biomass can be achieved by the application of a number of technologies, each with its specific requirements, advantages and disadvantages. The objective of ADRESS is to apply synthesis and design techniques for the generation of intensified sustainable processes for the production of biofuels.
