Biofuels are a realistic alternative or supplement to fossil fuels for transportation purposes, helping reduce emissions and providing energy security.
Reducing emissions from transportation
Traditionally, the transportation sector has been almost entirely dependent on fossil fuel based products. As transport is a major contributor to energy consumption and CO2 emissions, it is important to push developments of alternative fuel sources, which can replace a significant part of traditional fuels.
1st, 2nd and 3rd generation biofuels
Biofuel technology can be divided into several categories:
- First generation biofuels: Which are made from sugar, starch, vegetable oil or animal fat; raw materials that be used as food. The technology for 1G biofuels is already well developed.
- Second generation biofuels: Which are produced from non-food raw materials, for instance ethanol produced from the cellulose content of wheat stalks or other inedible waste products.
- Third generation biofuels: Also called Blue Biomass, which are produced from algae. This technology is still in the experimental stage with several projects working to determine the feasibility of this source.
Denmark a front-runner in 2G bioethanol development
Denmark has a leading position in 2G (cellulosic) bioethanol development with public, private and research institutions working closely together to develop this technology. Needed waste products are readily available and the production of 2G ethanol may result in valuable byproducts that can be used for animal feed and solid fuels.
