Did you know that the aviation industry alone is responsible for around 2.5% of global greenhouse gas emissions, despite accounting for only 2.5% of the world’s transportation sector? And of that 2.5%, a whopping 97% comes from fossil fuels. It’s no wonder that the aviation industry is under increasing pressure to reduce its carbon footprint – a challenge that could be solved by the burgeoning world of next-gen biofuels.

Next-gen biofuels, which are made from non-food biomass sources such as agricultural waste, algae, or even industrial waste gases, have the potential to significantly reduce the carbon intensity of our transportation systems. These fuels are not only more sustainable than their fossil fuel counterparts, but they also offer improved performance and reduced emissions.
One of the most promising next-gen biofuels is a type of fuel made from waste biomass, such as agricultural waste or sewage sludge. This fuel is produced through a process called gasification, which involves heating the biomass in the absence of oxygen to produce a synthesis gas, or syngas. The syngas is then converted into a liquid fuel through a process called Fischer-Tropsch synthesis.

Another exciting area of research is the use of algae as a feedstock for biofuels. Algae have the unique ability to absorb CO2 from the atmosphere, making them a net-negative-carbon fuel source. Plus, algae can be grown on marginal land, reducing competition with food crops and minimizing land-use changes that contribute to deforestation.
But next-gen biofuels aren’t just limited to the aviation industry. The shipping and trucking industries, which are responsible for a significant portion of global greenhouse gas emissions, are also turning to next-gen biofuels as a way to reduce their carbon footprint.
In fact, several companies are already working on commercializing next-gen biofuels for these industries. For example, a company called Red Rock Biofuels is working on producing jet fuel from waste biomass, while a company called Fulcrum BioEnergy is producing diesel from municipal solid waste.
Of course, there are still significant challenges to overcome before next-gen biofuels can become a mainstream reality. One of the biggest hurdles is the cost of production, which is still higher than that of traditional fossil fuels. However, as the industry scales up and costs come down, we can expect to see a significant shift towards next-gen biofuels.
In fact, many experts believe that next-gen biofuels could play a critical role in meeting the Paris Agreement’s goal of limiting global warming to 1.5°C above pre-industrial levels. With the right investment and policy support, next-gen biofuels could help reduce greenhouse gas emissions from transportation by as much as 80% by 2050.
The future of transportation is looking brighter than ever, thanks to the groundbreaking world of next-gen biofuels. Whether it’s powering our planes, ships, or trucks, these fuels have the potential to transform our transportation systems and help us achieve a more sustainable future.
