What is Green Diesel?
Green diesel is a second-generation biofuel made from renewable feedstocks such as vegetable oils, animal fats, and used cooking oil. Unlike biodiesel, which is produced through a process called transesterification, green diesel is made using a process called hydrotreating, which involves treating the feedstock with hydrogen under high pressure. The result is a high-quality hydrocarbon fuel that is chemically similar to petroleum-based diesel, allowing it to be used as a drop-in replacement in existing diesel engines without modification.
According to a Green Diesel Market report, the industry is expected to grow significantly in the coming years.
Environmental and Operational Advantages
1. Lower Emissions:
Green diesel significantly reduces lifecycle greenhouse gas emissions—by up to 80% compared to conventional diesel. It also produces fewer particulates, nitrogen oxides (NOx), and other air pollutants, making it a cleaner option for urban transport and freight logistics.
2. Compatibility:
One of green diesel's most compelling benefits is its compatibility with existing infrastructure. Unlike other renewable fuels that may require engine or fueling system modifications, green diesel can be used in current diesel engines, pipelines, and storage systems without disruption.
3. Improved Performance:
Green diesel offers excellent cold-weather performance, higher cetane numbers (a measure of combustion quality), and cleaner combustion, which can extend engine life and reduce maintenance costs.
Driving Clean Transportation
The transportation industry, especially heavy-duty sectors such as trucking, aviation, and maritime shipping, faces unique decarbonization challenges. While electric vehicles (EVs) are transforming passenger transport, green diesel provides an immediate and scalable solution for hard-to-electrify segments.
1. Freight and Logistics:
Major logistics companies are turning to green diesel to meet sustainability goals. Its availability and compatibility with diesel trucks make it an ideal interim solution while electrification infrastructure develops.
2. Public Transit and Municipal Fleets:
Cities and transit authorities are increasingly using green diesel to lower the carbon footprint of buses, waste collection trucks, and emergency vehicles.
3. Aviation and Marine:
Research and pilot projects are exploring green diesel as a blend or alternative for sustainable aviation fuel (SAF) and low-emission marine fuels.
A Stepping Stone to Net-Zero
While green diesel is not a silver bullet, it represents a critical stepping stone in the transition to net-zero transportation. It allows for immediate emission reductions without waiting for long-term infrastructure or technological overhauls. When paired with advances in carbon capture, waste feedstock recycling, and circular bioeconomies, green diesel could play a pivotal role in building a resilient, low-carbon transportation system.
Policy and Market Momentum
Supportive policies such as California’s Low Carbon Fuel Standard (LCFS), the European Union’s Renewable Energy Directive (RED II), and incentives for sustainable fuels in countries worldwide are accelerating green diesel adoption. Global production capacity is rapidly expanding as refineries pivot toward renewable fuel production.
