The Rise of Biofuels in Europe
Biofuels are increasingly being seen as a potential solution to Europe’s growing energy challenges, especially as the ongoing conflict in the Middle East continues to impact global oil supplies. European Commissioner Dan Jørgensen has called on member states to develop strategies aimed at reducing reliance on oil and gas, particularly within the transportation sector. This comes after a recent meeting of ministers on 31 March, where they discussed the global shortage of 11 million barrels of oil per day.
A significant concern is the closure of the Strait of Hormuz, a critical route for global oil shipments that accounts for about one-fifth of the world’s oil supply. Approximately 20% of diesel consumed in the EU and UK comes from the Gulf region, according to Alkagesta, a commodity trading company.
In a letter obtained by [SOURCE], 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.
What Are Biofuels?
The use of biofuels is not a new concept. Under the revised Renewable Energy Directive, EU countries are required to achieve a 29% share of renewable energy in transport by 2030, with 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 sources:
- 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.
While using plants as fuel still emits CO2 into the atmosphere, many biofuel companies argue that this level of emissions 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 enough renewable resources to power its transport sector without relying on fossil fuels in the long term. Professor Thomas Hirth from KIT stated, “If we use residual and waste materials efficiently, we can make road traffic less dependent on energy imports while reducing CO₂ emissions.”
The report, commissioned by BMW AG, found that large quantities of residual and waste materials can be used to produce fuels, such as agricultural straw, forestry wood scraps, and organic waste. It also highlighted the potential of energy crops grown on low-yield land that do not compete with food production.
Professor Tomas Kock from KIT’s Institute of Internal Combustion Engines (IFKM) added, “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 success depends on governments and the public prioritizing the production of advanced reFuel biofuels.
Despite these claims, some climate experts remain skeptical. Lucien Mathiew, cars director at Transport & Environment, argues that e-fuels are at best a “niche solution” in road transport. He believes that transitioning to electric vehicles (EVs) is a more practical approach.
“EVs offer a clean, efficient technology that is cheap enough for the mass market,” Mathiew explains. “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.”
The Controversy Surrounding Biofuels
Biofuels are often promoted as a solution to reduce dependence on fossil fuels, but they come with several disadvantages. Many biofuels are made from staple crops like corn and soybeans, which can lead farmers to prioritize growing fuel over food. This can drive up global food prices and worsen food insecurity, especially in low-income countries.
An investigation in Congo last year revealed that an EU biofuel project risked the country’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 be used to feed 120 million people or absorb twice as much CO2 if returned to nature.
Using just 2.5% of this land for solar panels would generate the same amount of energy, according to the report. This has led some climate experts to label biofuels as a “failed experiment” and instead advocate for a shift towards wind and solar energy.
“Right now we surrender vast swathes of land for crops that we simply burn in our cars,” says Maik Marahrens, T&E’s biofuels manager. “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.”
While biofuels are considered renewable in theory, growing crops like sugarcane, soy, and corn for energy has also been linked to deforestation in crucial environments such as the Amazon rainforest. This raises questions about whether biofuels are truly carbon neutral, as the process of growing, harvesting, and processing these crops requires significant energy, often derived from fossil fuels.
