Biofuel demand in 2021 reached 4 EJ (exajoules) (159 200 million litres), returning to near 2019 levels after a decline due to the Covid-19 pandemic, noted International Energy Agency in its latest report. In 2021 biofuels represented 3.6% of global transport energy demand, mainly for road transport. Although overall biofuel demand bounced back to 2019 levels after a decline due to the pandemic, the rebound has been uneven across specific biofuels. Ethanol demand grew by 6% from 2020 to 2021, yet remains 7% lower than 2019 demand. Biodiesel (referring to FAME) inched past 2020 demand by 0.3% to reach 1.4 EJ. Renewable diesel (referring to HVO) continued its exponential growth to reach 65% higher consumption in 2021 compared to 2019, reaching over 0.3 EJ. Biodiesel and renewable diesel compete for the same feedstock, further complicating the relative growth between the two biofuels.
