HF Sinclair is an independent energy company with operations across refining, midstream, and marketing, plus involvement in renewable diesel, specialty lubricants, asphalt, and chemicals. It refines crude oil into light products such as gasoline, diesel, and jet fuel, and also produces renewable diesel and other specialty products for commercial and industrial customers. Its five-area structure covers downstream refining, midstream logistics, and marketing to a diverse customer base, with additional international activity in Canada and the Netherlands. Unlike many peers that focus on a single segment, HF Sinclair integrates multiple stages of the energy value chain—from producing and processing fuels to distributing them—while expanding into renewable and specialty product areas. The company aims to grow its footprint across the energy value chain, broaden its product slate (including renewables and chemicals), and strengthen its presence in North American and international markets.

Three US refiners to watch as fuel costs lift margins: Marathon Petroleum, HF Sinclair, PBF

Higher fuel costs are pushing up airfares, delivery fees, and trucking prices, and putting US refiners in focus. Simply Wall St highlights three that stand to gain when refining margins hold firm. HF Sinclair has about $31.2 billion in annual revenue, $27.7 billion of it from refining, and a market value of about $22.3 billion. The WTI 3-2-1 crack spread was around $59 per barrel in mid 2026, with several million barrels per day of global refining capacity offline. Marathon Petroleum earns about $144.6 billion from refining and marketing and has a market value near $134.3 billion. It is investing in refineries at Galveston Bay, Garyville, Robinson, and El Paso. PBF Energy has a market value near $10.1 billion and made about $34.4 billion from refining. It recently bought the Torrance hydrogen plants.

HF Sinclair launches cooling fluid for direct-to-chip environments.

HF Sinclair launches cooling fluid for direct-to-chip environments. Oil company follows on from launch of immersion fluid in 2024 October 06, 2026 Oil company HF Sinclair has launched a new cooling fluid for direct-to-chip environments. Innovate, the liquid cooling brand from HF Sinclair's lubricants and specialties business, announced this week the launch of Innovate DTC25, a new propylene glycol-based direct-to-chip cooling fluid. The launch expands Innovate's liquid cooling portfolio beyond immersion cooling into direct-to-chip environments. The company said the new product has been developed in alignment with Open Compute Project's (OCP) Base Specification for PG25 heat transfer fluids. DTC25 Fluid is a pre-mixed, ready-to-use heat transfer fluid formulated with high-quality propylene glycol and high-purity deionized water. The company said the formulation uses Organic Acid Technology (OAT) inhibitors to support long-term corrosion protection against copper, steel, brass, cast iron, and aluminum, and incorporates a biostatic formulation to help maintain fluid integrity over its extended service life, freeze protection for sub-zero conditions, and fluorescent blue dye to support early leak detection. The fluid is also free of nitrite, amine, phosphate, and silicate and designed to meet OCP PG25 materials compatibility guidelines. Innovate noted that as the fluid is pre-mixed, operators can eliminate on-site mixing requirements and ensure a consistent fluid composition at installation, simplifying commissioning and ongoing management. "Innovate DTC25 fluid draws on decades of experience formulating high-performance fluids for demanding OEM applications and applies that expertise to the next generation of data center cooling," said Alex Buczek, director, new business development, HF Sinclair lubricants and specialties. "As liquid cooling architectures continue to evolve, customers need more than a fluid supplier. They need partners that understand fluid performance, system protection and the demands of critical infrastructure. Expanding into direct-to-chip cooling is a natural extension of the expertise and relationships we have built across the liquid cooling ecosystem." Based in Texas, NYSE-listed HF Sinclair produces gasoline, diesel fuel, jet fuel, renewable diesel and other specialty products. The company owns and operates refineries in Kansas, Oklahoma, New Mexico, Wyoming, Washington, and Utah. The company launched an immersion cooling fluid for data centers in 2024. Many petrochemical firms have moved to diversify into serving data center customers. Oil companies such as Shell, Castrol, ExxonMobil, ENEOS, Gulf Oil, Petronas and Perstorp, and SK Enmove are among the businesses bringing immersion cooling fluids to market. US food giant Cargill and chemical firm Chemours have also launched fluids. Shell added a direct-to-chip cooling fluid to its portfolio last year. HF Sinclair was founded as Sinclair Oil Corporation in 1916, while General Appliance Corporation was founded in 1947. General Appliance Corporation changed its name to Holly Corporation, and later to HollyFrontier after acquiring Frontier Oil in 2011. The company became HF Sinclair after acquiring Sinclair Oil in 2021. More in cooling.

Phillips 66, Kinder Morgan and HF Sinclair announce FID for Western Gateway refined products pipeline.

Phillips 66, Kinder Morgan and HF Sinclair announce FID for Western Gateway refined products pipeline. 8/11/2026 12:00:00 PM Phillips 66, Kinder Morgan, Inc. and HF Sinclair Corporation announced they have finalized a joint venture agreement and made a final investment decision to move forward with the proposed Western Gateway Pipeline system (Western Gateway). Under the joint venture, Phillips 66, Kinder Morgan and HF Sinclair will own 49.9%, 35.1% and 15% of the system, respectively. "The final investment decision reflects the strength of this industry partnership. By combining the capabilities of Phillips 66, Kinder Morgan and HF Sinclair, Western Gateway is expected to strengthen fuel supply reliability and deliver a more cost-effective, resilient path for growing markets across the West," said Phillips 66 Chairman and CEO Mark Lashier. "This project will connect our Central Corridor and Gulf Coast refining assets to our West Coast and Southwest Marketing assets and demonstrates the value of our integrated business model and the opportunities it creates." Kinder Morgan CEO Kim Dang added, "This project brings together strategic supply access, existing infrastructure and experienced operators to improve affordability and assurance of supply for customers in the Western United States. Kinder Morgan is proud to contribute its long-standing presence and decades of experience safely and reliably serving the region's energy needs. We expect to earn attractive returns on our investment based on the incremental project earnings above those of our contributed assets." "We believe in the merits of Western Gateway and are proud to be a part of such a transformational endeavor shaping the fuels markets of the West," said Franklin Myers, CEO, HF Sinclair. Western Gateway is a proposed 1,300-mile refined products pipeline system that would create a new fuel supply path from St. Louis, Missouri, and expanded Gulf Coast origin points to Arizona and California. With a design capacity of 230,000 barrels per day, the project is also being developed to allow for future expansion with limited capital and no new pipe necessary as future demand requires. The project will include: * Approximately 900-mile new-build 20-inch and 24-inch pipeline from Borger, Texas, to Phoenix, Arizona. Phillips 66 will construct and operate the new-build pipeline. * Kinder Morgan's contribution of its existing SFPP East Line pipeline from El Paso, Texas to Phoenix and Tucson, Arizona, and its SFPP West Line pipeline from Colton, California, to Phoenix, which would be reversed to move product east to west into California. Kinder Morgan will continue to operate those pipelines. * Supply to Western Gateway would also be supported by Phillips 66's Gold Pipeline, which will connect to the Explorer Pipeline. The Gold Pipeline would be reversed to allow refined products to flow toward Borger. The project's enterprise value is approximately $5 billion. Upon completion of the new build pipeline from Borger into Phoenix, Kinder Morgan's existing SFPP East Line and West Line assets would be contributed to the joint venture at a value of approximately $1.5 billion. Based on the approximately $5 billion enterprise value, Kinder Morgan will also make cash contributions of approximately $250 million. Phillips 66 would make cash contributions of approximately $2.5 billion, and HF Sinclair would make cash contributions of approximately $750 million to the project. The new system is underpinned by primarily 10-year, take-or-pay contracts. It is expected that the midstream project will generate attractive returns consistent with the high-quality, long-term contracted volumes that underpin the project. The Western Gateway project is targeting completion in 2029, subject to the receipt of all permits and regulatory approvals.

Phillips 66, Kinder Morgan, HF Sinclair approve Western Gateway Pipeline project.

Phillips 66, Kinder Morgan, HF Sinclair approve Western Gateway Pipeline project. August 11, 2026 EnergyNow Media By Reuters (Reuters) - Phillips 66, Kinder Morgan and HF Sinclair said on Tuesday they have finalized a joint venture agreement and decided to proceed with the proposed $5 billion Western Gateway Pipeline system. Phillips 66 will own 49.9% of the joint venture, Kinder Morgan 35.1% and HF Sinclair 15%, they added. Companies have been racing to build a major new fuel pipeline to the U.S. West Coast ahead of planned refinery closures in California, a relatively isolated fuel market with limited pipeline links to major refining hubs that leave it vulnerable to supply disruptions and price spikes. The project is expected to be completed in 2029. Reporting by Pooja Menon in Bengaluru; Editing by Jonathan Ananda Share This:
