2. The International Energy Agency (IEA) identifies biofuel as a major player in the decarbonisation of the transport sector.3 The IEA projects global annual biofuel production will increase tenfold to 840 gigalitres by 2060.4 As a proportion of all fuel, the amount of biofuel currently produced in Australia sits below the global average.

Biofuels versus climate change: Exploring potentials and

As we progress, biofuels should be seen as part of an integrated solution that includes other renewable sources and energy efficiency practices, to build a resilient and sustainable energy future. Each generation of biofuels brings its own set of challenges and benefits that need to be considered in the context of global energy transition and

Renewable fuels – Renewables 2024 – Analysis

For the first time in the IEA Renewable Market Report series, we are dedicating a specific chapter to renewable fuels. These fuels include solid biomass (excluding for traditional uses), liquid biofuels, biogases (biogas and biomethane), electrolytic hydrogen made from renewable electricity (renewable hydrogen) and e-fuels (fuels made from renewable hydrogen, including e

Biofuels and their sources of production: A review on cleaner

Biofuels can be utilizing as fuel additives or in their pure form. Further, biofuels are commonly classified into bioethanol and biodiesel [5].The liquid biofuels can be utilized as an alternative source for conventional fuels in the transportation sector, contributing to approximately 18% of primary energy consumption [1], [6].Today, approximately 80% of liquid biofuel is
