New Research In

Transport has become the single biggest emitter of greenhouse gases in Europe. Fuel suppliers are obliged to blend 6. The RED has generated greater demand for biofuels and therefore for agricultural land.

Green Technology - Documentary

Carbon stores such as forests and peatlands are converted to crop fields, which results in a loss of biodiversity and increases in greenhouse gas emissions as sequestered carbon is liberated. These indirect emissions are currently not accounted for when biofuels are considered for the RED. According to the globiom study land expansion leads to 6.

Can Biofuels Alleviate the Energy and Environmental Crisis?

The amount of palm oil used in biodiesel has increased significantly in recent years. Cars and trucks now burn almost half of palm oil used in Europe. Book navigation. Biofuels Introduction Background What the science says Why is palm oil biodiesel bad?

Biofuels can help solve climate change, especially with a carbon tax

What's happening? What is ILUC indirect land-use change?

How much land will be converted? Some buses, trucks, and military vehicles in the U. Renewable diesel, a chemically different product that can be derived from fats or plant-based waste, is considered a "drop-in" fuel that does not need to be blended with conventional diesel.

Other types of plant-based fuel have been created for aviation and shipping. More than , flights have used biofuel, but the amount of aviation biofuel produced in accounted for less than 0.

In shipping, too, adoption of biofuel is at levels far below the targets set by the International Energy Agency. Renewable natural gas, or biomethane , is another fuel that potentially could be used not only for transportation but also heat and electricity generation.

Gas can be captured from landfills, livestock operations, wastewater, or other sources. This captured biogas then must be refined further to remove water, carbon dioxide, and other elements so that it meets the standard needed to fuel natural-gas-powered vehicles. A variety of materials, or feedstocks, can be used to make biofuels. Though corn and sugarcane are well-established ethanol feedstocks, the process of growing the crops, making fertilizers and pesticides, and processing the plants into fuel consumes a lot of energy—so much energy that there is debate about whether ethanol from corn actually provides enough of an environmental benefit to be worth the investment.

So scientists and startups are exploring other materials that have the potential to serve as fuel without the accompanying concerns about food supply and environmental impact. Cellulosic ethanol , for example, uses corn stover, wood waste, or other plant material that would not be used otherwise.

Other potential biofuel feedstocks include grasses , algae , animal waste , cooking grease , and wastewater sludge , but research continues to find the most efficient and cost-effective ways to transform them into usable fuel. Photograph by Mark Thiessen.
