The Rise of Biofuels in Europe
As Europe grapples with the rising costs of oil due to ongoing conflicts, biofuels are increasingly being considered as a viable alternative. European Commissioner Dan Jørgensen has called for member states to implement measures aimed at reducing reliance on oil and gas, especially within the transportation sector. This call comes after ministers met to address a global shortfall of 11 million barrels of oil per day.
The Strait of Hormuz, a critical chokepoint for global oil supply, is under significant concern following its effective closure. Approximately one-fifth of the world’s oil passes through this strategic waterway. In the EU and UK, around 20% of diesel consumed originates from the Gulf region, according to Alkagesta, a commodity trading company.
In a letter obtained by various sources, the EU has been advised to explore biofuels as an alternative to fossil fuels. This idea has gained traction since the conflict in the Middle East began, highlighting the potential of biofuels in addressing energy shortages.
Understanding Biofuels
Biofuels have long been part of the renewable energy strategy. Under the revised Renewable Energy Directive, EU countries are required to achieve a 29% share of renewable energy in transport by 2030. This includes a sub-target of 5.5% for renewable hydrogen and advanced biofuels.
Biofuels are derived from plant materials and can be categorized based on their source:
- First-generation biofuels come from food crops such as corn and sugar cane.
- Second-generation biofuels are made from inedible vegetation and agricultural waste.
- Third-generation biofuels are sourced from algae.
Although using plants as fuel still emits CO2, many biofuel companies argue that the carbon released is equivalent to what was absorbed during the crop’s growth.
Can Biofuels Replace Fossil Fuels?
A recent study conducted by the Karlsruher Institut für Technologie (KIT) suggests that Europe has the potential to power its transport sector without relying on fossil fuels in the long term. According to Professor Thomas Hirth, if residual and waste materials are used efficiently, road traffic could become less dependent on energy imports while also reducing CO₂ emissions.
The report, commissioned by BMW AG, found that substantial amounts of residual and waste materials can be converted into fuels. These include straw from agriculture, wood scraps from forestry, and organic waste. It also identified energy crops that grow on low-yield land and do not compete with food production as potential sources of biofuel.
Professor Tomas Kock from KIT’s Institute of Internal Combustion Engines (IFKM) noted, “The really great potential is in materials like plant residues and wood fiber, which are produced in many processes anyway and can provide sufficiently climate-friendly fuels.” However, he emphasized that this success depends on government and public support for the production of advanced reFuel biofuels.
Despite these promising findings, some climate experts remain skeptical about the effectiveness of biofuels. Lucien Mathiew, cars director at Transport & Environment, argues that e-fuels are at best a “niche solution” in road transport. He advocates for transitioning to electric vehicles (EVs), which offer a clean, efficient technology that is becoming more affordable for the mass market.
“European lawmakers should focus on industrial policies to deliver battery factories, secure the supply of critical raw materials, and build an EV industry that can compete globally with China,” Mathiew explains.
The Controversy Surrounding Biofuels
While biofuels are often promoted as a solution to reduce dependence on fossil fuels, they come with several disadvantages. Many biofuels are produced from staple crops like corn and soybeans, which can lead farmers to prioritize growing fuel over food. This can increase global food prices and exacerbate food insecurity, particularly in low-income countries.
An investigation in Congo revealed that an EU biofuel project risked the nation’s food security, despite claims that only “degraded lands” were being used. A 2023 study by T&E found that Europe wastes land the size of Ireland on crops for biofuels. This land could feed 120 million people or absorb twice as much CO2 if returned to nature.
Using just 2.5% of this land for solar panels could produce the same amount of energy, according to the report. This has led some climate experts to label biofuels as a “failed experiment,” advocating instead for a transition to clean power through wind and solar.
Maik Marahrens, T&E’s biofuels manager, stated, “Right now we surrender vast swathes of land for crops that we simply burn in our cars. This land could feed millions of people or, if given back to nature, provide carbon sinks rich in biodiversity. Crop biofuels are probably the dumbest thing ever promoted in the name of the climate.”
Moreover, growing crops like sugarcane, soy, and corn for energy has been linked to deforestation in critical environments such as the Amazon rainforest. This raises questions about whether biofuels truly are carbon neutral, as the processes involved require significant energy, often derived from fossil fuels.
