Did you know that in 2020, the International Energy Agency (IEA) reported that biofuels accounted for less than 2% of the world’s total fuel consumption? Sounds like a small number, right? But what’s even more astonishing is that this figure is expected to quadruple by 2050, driven largely by the emergence of next-generation biofuels (NGBs). These cutting-edge fuels are set to transform the transport sector, reducing greenhouse gas emissions and dependence on fossil fuels.

So, what exactly are next-gen biofuels? Simply put, they are advanced versions of biofuels that offer several key advantages over traditional biofuels. Unlike their predecessors, NGBs can be produced from a wide range of non-food biomass feedstocks, such as agricultural waste, algae, and even municipal waste. This means that they can be grown and harvested on marginal land, reducing competition with food crops and land-use change.
But that’s not all. Next-gen biofuels also boast significantly higher energy densities than traditional biofuels, making them a more efficient and effective alternative to fossil fuels. This is particularly important for long-haul transportation, where fuel efficiency can make all the difference between profit and loss.

One of the most exciting developments in the NGB space is the emergence of low-carbon aviation fuels. These fuels are specifically designed for use in aircraft engines and have the potential to reduce greenhouse gas emissions from air travel by up to 80%. This is no small feat, given that aviation accounts for around 2.5% of global CO2 emissions.
Another area where next-gen biofuels are making a significant impact is in the shipping industry. The International Maritime Organization (IMO) has set ambitious targets to reduce greenhouse gas emissions from shipping by at least 50% by 2050. Next-gen biofuels are seen as a key part of the solution, offering a cleaner alternative to traditional bunker fuels.
So, what’s driving the rapid growth of next-gen biofuels? For one, there’s the growing recognition of the urgent need to address climate change. Governments and policymakers around the world are increasingly looking to biofuels as a key part of their energy transition strategies. Meanwhile, the private sector is stepping up to the plate, with major companies like BP, ExxonMobil, and Shell investing heavily in NGB development.
Of course, there are still challenges to be addressed. Next-gen biofuels can be more expensive to produce than traditional biofuels, which can make them less competitive in the market. But as economies of scale improve and technology advances, these costs are expected to come down.
In conclusion, next-gen biofuels are poised to revolutionize the transport sector, offering a cleaner, more efficient alternative to fossil fuels. As the world continues to grapple with the challenges of climate change, it’s clear that NGBs will play a key role in the transition to a low-carbon economy. Whether it’s aviation, shipping, or road transport, next-gen biofuels are set to be the fuel of the future.
