Biofuels are being reconsidered over and over again in the aviation industry to provide a more affordable and abundant biofuel for airplanes. The carbon waste streams can not get replaced with energy crops. If biofuels become a common use fuel, more airlines will choose biofuels due to easy availability and lower costs. Every place today either has one of the biofuel crops growing around or have industrial plants that produce enough carbon dioxide to create plenty of feedstock. Here are the best feedstocks or biofuels that can get commonly operable in the coming years.
Boeing and Etihad Airways have already started the cultivation of Salicornia Bigelovii, which is an edible succulent naturally found in the Caribbean and the southern US. Brackish water is suitable for these crops while getting fertilized by shrimp and tilapia. Saltwort can also be a tender vegetable that is edible, but the main reason for its cultivation is its abundance of oil seeds that can produce biofuel for aviation industries. An experiment on saltwort revealed that the biofuel made from saltwort could reduce the greenhouse gas emission by 38-68%. It can be the next big energy option in the aviation industry.
Energy cane is a genetically altered sugar cane crop that is intended to grow more fiber than sucrose. Due to the necessary conditions for growing sugar cane, it can be hard to grow in many places around the world. That is why it is produced using genetic optimization, which can be used to burn energy with its heave fiber content.
Some biofuels that can be made from waste are able to solve the issues of growing biofuel crops. Due to lack of land, hike in food prices, and odd growing conditions, the energy crops can create more losses for the industry. Instead, using waste gas that is formed using microbes that produce liquid fuels from waste is said to be a better idea. Waste gas production can help in recycling the carbon that has been used already instead of growing more carbon. It will save the cultivation cost, land utilization, and other expenses on growing crops.
Another recyclable biofuel can be formed from the woods that remain in the factories after the useful wood is trimmed and sent to paper mills. Today when technology is growing at a rapid rate, the use of wood for making paper will also slow down. This lumber can then be used as a biofuel in the aviation industry to create clean jet fuel.
Palm oil is a promising biofuel that can be grown in abundance but in a controlled environment. Palm oil has a terrible history of burning rainforests in Indonesia. But palm can be a high yielding crop. If we can grow is sustainably in a controlled environment with the right measures and certifications, it can be a beneficial alternative biofuel for the aviation industry.
