Introduction In the 1930’s, the aviation industry was in the midst of the major transformation as aircraft manufacturing was

getting modernized……… Changes in aviation with

different era….

What are biofuels?

Produced from renewable biological resources such as plant material (rather than traditional fossil fuels like coal, oil and natural gas).

Absorbs carbon dioxide from the atmosphere as the plant matter (biomass) is grown, which is then released back into the atmosphere when the fuel is burnt.

First-generation biofuels have been used for a number of years for transport, home heating, power generation from stationary engines, and cooking.

Second-generation biofuels are derived from new sources that do not compete for resources with food supplies and can be used in aviation

biofuels can be produced from anyrenewable biological carbon material, although the mostcommon sources are plants that absorb carbon dioxide(CO2) and use sunlight to grow.

plants rich in sugars (first-generation biofuels)

bio-derived oils (second-generation biofuels)

FIRST-GENERATION BIOFUELS Crops that are rich in sugars (such as sugar cane) or starch (such as corn)

SECOND-GENERATION BIOFUELS commonly sourced from non-food plants

processed and can either be burned directly or converted by chemical processes to make high-quality jet and diesel fuels

Jatropha: produces seeds containinginedible lipid oil that can be used to produce fuel. Eachseed produces 30 to 40% of its mass in oil.

Camelina: camelina oil is as a feedstock to produce renewable fuels. The left over “waste” from the oil extraction can also be used as feedfor chickens in small proportions.

Algae are potentially the most promising feedstock for producing large quantities of sustainable aviation biofuel. It can be grown in polluted or salt water, deserts and other inhospitable places. They thrive off carbon dioxide, which makes them ideal for carbon capture (absorbing carbon dioxide) from sources like power plants.

Halophytes are salt marsh grasses

ADVANTAGES OF SECOND-GENERATION BIOFUELS FOR AVIATION

DIVERSIFIED SUPPLYThe production of sustainable biofuelsis flexible and biofuel feedstock can be grownin many places around the world accordingto the aviation industry’s needs and demands

Relative to fossil fuels, sustainably produced biofuelsresult in a reduction in CO2 emissions across theirlifecycle.

ENVIRONMENTAL BENEFITS

Diversified SupplyThe production of sustainable biofuels is flexible and biofuel feedstock can be grown in many places around the world according to the aviation industry’s needs and demands…….

Economic benefits to parts of the world that have large amounts of marginal or unviable land for food crops, but are suitable for growing second-generation biofuel crops
