As the world intensifies its push toward sustainability, tackling greenhouse gas (GHG) emissions is more crucial than ever. One innovative solution gaining traction is renewable diesel (RD)—a cleaner, more sustainable alternative to traditional fuels. 

Unlike conventional biodiesel, renewable diesel is created through advanced hydroprocessing, producing a fuel that mimics fossil diesel’s properties while significantly reducing its environmental impact.

This article dives into how renewable diesel, especially through Neste’s cutting-edge technology, is revolutionizing the marine industry by reducing carbon intensity and paving the way for a greener future.

Renewable Diesel: What Makes It Different?

Renewable diesel isn’t your average biofuel. Derived from sustainable sources like used cooking oil, animal fats, and agricultural residues, it undergoes hydroprocessing to deliver a high-quality fuel. This process yields a product indistinguishable from fossil diesel but with a fraction of its carbon footprint.

Compared to biodiesel, renewable diesel offers higher energy content, better fuel stability, and seamless compatibility with existing diesel engines. Whether it’s powering trucks, buses, or marine vessels, renewable diesel works without the need for expensive engine modifications, making it a practical and scalable solution for reducing GHG emissions.

How Renewable Diesel Helps Reduce Marine Carbon Emissions

The maritime industry plays a significant role in global carbon emissions, contributing around 2-3% of the total greenhouse gases (GHG) worldwide. With the size of the global shipping fleet on the rise, finding ways to decarbonize this essential sector has become crucial to meeting international climate goals.

Renewable diesel has emerged as a powerful solution in this transition, offering a practical and effective way to lower the carbon intensity of marine operations.

Marine vessels, ranging from massive commercial cargo ships to luxurious yachts, are major polluters, primarily due to their reliance on heavy fuel oil (HFO), which contains high levels of sulfur and carbon. By switching to renewable diesel, the maritime industry could reduce GHG emissions by up to 90%. This shift has the potential to significantly cut the environmental impact of global shipping and maritime transport

Environmental Advantages of Renewable Diesel

1. Lifecycle Greenhouse Gas Reduction

Renewable diesel can reduce GHG emissions by up to 90% compared to fossil diesel. This significant reduction is due to the sustainable feedstocks used, such as waste oils and fats, which would otherwise release methane if left to decompose. By converting these materials into fuel, renewable diesel helps lower overall carbon emissions.

2. Reduction in Harmful Pollutants

Renewable diesel produces fewer harmful emissions than traditional diesel. It contains no aromatics, which are linked to toxic particulate matter (PM), and has ultra-low sulfur content, making it compliant with global sulfur standards. This helps reduce air pollution in marine and coastal areas, improving air quality and lowering the risk of acid rain.

3. Compatibility and Performance

Renewable diesel is fully compatible with existing diesel engines, requiring no modifications. It provides 44 MJ/kg of energy, similar to fossil diesel, ensuring comparable or better mileage. Additionally, its high cetane number results in smoother engine operation, improved cold starts, and longer engine life.

Singapore’s Role in Renewable Diesel Adoption

Singapore is leading the way in adopting renewable diesel, becoming a key hub for sustainable energy. Its strong financial infrastructure, strategic location, and pro-sustainability policies make it an ideal place for clean energy investments, including scaling up renewable diesel projects.

SEACEF’s Clean Energy Focus

The Southeast Asia Clean Energy Facility (SEACEF) has been instrumental in advancing renewable energy in Southeast Asia. By focusing on early-stage solutions, SEACEF has supported the growth of renewable diesel projects. Its development-stage capital bridges the gap between initial concepts and large-scale deployment, ensuring efficient use of funds for lasting environmental and economic impact.

Singapore’s Adoption of Renewable Diesel

In Singapore, several organizations are leading the way in renewable diesel adoption. The Certis Group has implemented a pilot program using Esso’s renewable diesel R20 in its commercial fleet, reducing GHG emissions by 15.4%. This demonstrates that renewable diesel is both feasible and economically viable for urban logistics.

Additionally, Singapore’s public transport system is using renewable diesel to improve air quality. With government support and local environmental initiatives, renewable diesel is powering several public buses, contributing to a cleaner, healthier city environment.

Through these efforts, Singapore is not only enhancing its own energy sustainability but also setting a regional example for others to follow.

How Neste’s Renewable Diesel is Changing the Game in the Marine Industry

Neste, a leading global producer of renewable diesel, is revolutionizing the marine industry with its advanced NEXBTL™ technology. This process transforms a variety of feedstocks, including waste and residues, into high-quality, sustainable renewable diesel, offering a cleaner and more efficient fuel for both transportation and marine applications.

1. Cutting Marine Emissions with Neste’s Renewable Diesel

Neste’s renewable diesel is making waves in the marine sector by drastically reducing carbon emissions in an industry notorious for its environmental impact. By switching to Neste’s renewable diesel, marine operators can significantly cut their carbon intensity, making it easier to meet the International Maritime Organization’s (IMO) Carbon Intensity Indicator (CII) regulations aimed at decarbonizing the shipping industry.

2. Renewable Diesel: The Eco-Friendly Choice for Yachts and Luxury Vessels

Renewable diesel isn’t just for large commercial ships; it’s also gaining popularity in the luxury yacht industry. Yachts, often operating in pristine marine environments, benefit from renewable diesel’s reduced environmental footprint and high performance. Additionally, its non-toxic and biodegradable nature makes it a safer, more sustainable option in case of spills.

The Future of Renewable Diesel in the Marine Industry

As the world increasingly demands sustainable energy solutions, renewable diesel is set to play a pivotal role in decarbonizing the marine industry.

The benefits are undeniable: renewable diesel reduces lifecycle GHG emissions by up to 90%, enhances air quality, and is fully compatible with existing diesel engines. This makes it an ideal solution for a variety of applications—from commercial shipping fleets to luxury yachts.

Investing in a Sustainable Marine Future

Given its environmental and performance advantages, renewable diesel presents a major opportunity for the marine industry to significantly cut its carbon footprint. Companies in Singapore and beyond are already incorporating renewable diesel into their operations, setting a strong example for others to follow.

For industries aiming to stay ahead of the curve and contribute to global decarbonization efforts, investing in renewable diesel is a smart and strategic move. Not only does it offer immediate environmental benefits, but it also helps companies comply with future emissions regulations, ensuring long-term operational sustainability.

By adopting innovative technologies like Neste’s renewable diesel, the marine industry can make a real difference in creating a cleaner, more sustainable world. The future of marine energy is renewable—and the time to act is now.
