From Loss to Profitability

The financial results of the renewable diesel segment illustrate a significant operational turnaround and its growing importance to Valero’s bottom line. In the second quarter of 2025, the segment recorded a $79 million operating loss, highlighting its sensitivity to market conditions such as feedstock costs. However, by the second quarter of 2026, it reported a $717 million operating income. This dramatic swing demonstrates the validation of its large-scale production model and its ability to capitalize on favorable market dynamics and policy support.

Strategic Pivot to SAF

Looking beyond renewable diesel, Valero is positioning itself for the next phase of low-carbon fuel demand. In 2025, the company initiated a project to convert 50% of the DGD Port Arthur plant’s capacity to produce Sustainable Aviation Fuel (SAF). This move, designed to capitalize on incentives from the Inflation Reduction Act, allows Valero to enter the hard-to-abate aviation sector and diversify its renewable product portfolio, with the SAF facility expected to be operational in 2025.

$2 B in Low-Carbon Fuels, Valero Energy Renewable Diesel Investments

Valero’s market position is the result of a deliberate and substantial capital allocation strategy focused on building out its low-carbon fuels portfolio. The company’s reported investment plans through 2023 directly funded the critical infrastructure expansions that now form the backbone of its renewable diesel and future SAF operations, demonstrating a clear financial commitment to its strategic pivot.

Port Arthur Plant Investment

A significant portion of Valero’s low-carbon capital expenditure was directed toward the DGD Port Arthur plant. The construction and commissioning of this 470 million gallon per year facility, which came online in late 2022, was the cornerstone of its capacity expansion. This investment nearly doubled DGD’s production capability, providing the scale necessary to achieve its market-leading position and operational efficiencies.

Sustainable Aviation Fuel Upgrade

Following the successful expansion, Valero sanctioned further investment in its renewables segment. In January 2023, the DGD joint venture approved a project to upgrade the Port Arthur facility for SAF production. This investment gives the company the option to convert up to 235 million gallons of its annual capacity to SAF, a strategic allocation of capital to capture future growth in a premium, high-demand market.

Valero Energy 1 Major Partnership, Darling Ingredients JV (2021 to 2026)

Valero’s entire renewable diesel strategy hinges on its vertically integrated joint venture, Diamond Green Diesel (DGD), with Darling Ingredients. This cornerstone partnership provides a critical competitive advantage by securing a reliable feedstock supply chain, a key differentiator in the biofuels market. This model of deep integration with a specialized partner extends to other parts of its sustainability strategy, including efforts to decarbonize its established ethanol business.

Diamond Green Diesel JV Structure

The DGD joint venture is a strategic alignment of complementary strengths. Darling Ingredients leverages its extensive network to source and process feedstocks like used cooking oil and animal fats. Valero then applies its world-class refining operations and logistics network to produce and distribute the renewable diesel. This structure insulates the venture from feedstock market volatility and underpins its ability to operate at a scale of 1.2 billion gallons per year.

Black Rock and Navigator CCS Project

Beyond renewable fuels, Valero is addressing emissions from its other business lines. In 2021, the company partnered with Black Rock and Navigator to develop a large-scale Carbon Capture and Sequestration (CCS) system. This project is designed to capture and store CO 2 from its ethanol plants across five U.S. states, demonstrating a broader commitment to decarbonization by lowering the carbon intensity of its biofuel production.
