Cleaner fuels have been developed to partly replace fossil based fuels and make the energy demanding sectors more sustainable. Different to fossil fuels that are obtained from crude oil, cleaner fuels can be produced in various ways, and along with the understanding of implementation, technology and stationary factors, can have a positive impact. Cleaner fuels produced from used waste, vegetable oils and fats, as well as from municipal waste are ranked among the most sustainable and it is important for us to support those that safeguard our environment, support workers and communities, and raise the standard of living for all. Therefore, Flightnook’s approach focuses on more than just avoiding harmful consequences such as fracking and greenhouse gas emission. The overall situation matters to realize a positive socio-economic impact.
As mentioned, cleaner fuels can be produced in various ways, and to gain a better understanding, the following example refers to cleaner fuels derived from biomass – renewable feedstock. In that case, a reduction in carbon dioxide (CO2) and other unwanted emission savings comes from growing plants that absorb CO2 to convert sunlight into chemical energy in a process called photosynthesis. Those plants or their components eventually end up in a refinery as waste material to be converted into cleaner fuel. The fact that plants have absorbed CO2 to grow decreases the emissions before the cleaner fuel has been used. Combustion then releases CO2 back into the atmosphere, where it can be again absorbed by growing plants. Special energy plants exist, that can be grown complementary to food crops in hostile environments. Cleaner fuels can reduce CO2 emissions by up to 80% compared to fossil based fuels measured on a life cycle assessment. The 20% left contribute to the production and refinement of those cleaner fuels.
