Blue vs. Green Hydrogen Hedge: The Louisiana SAF Megaproject's Strategy to Build In Both Fuel Sources

A massive sustainable aviation fuel plant taking shape in Louisiana is betting on something unusual: not one, but two types of hydrogen production. DG Fuels just locked in a $15.7 million engineering contract with Samsung E&A for its St. James Parish facility, and the strategy behind this project could reshape how the industry approaches fuel security.

By integrating both blue hydrogen (produced from natural gas with carbon capture) and green hydrogen (made through water electrolysis), DG Fuels is hedging against energy price swings while chasing the lowest possible carbon footprint.

Samsung E&A Takes the Engineering Lead

On December 12, 2025, Samsung E&A signed the Front-End Engineering Design contract for the Louisiana SAF Production Project. The South Korean engineering giant will handle the entire clean hydrogen production package, covering both production pathways.

The FEED work will run approximately 10 months, setting up the technical foundation for a final investment decision expected by Q3 2026. Commercial production could start in 2028.

Samsung will collaborate with Black & Veatch, which serves as the overall system integrator. The two companies are also discussing extending their partnership to DG Fuels' planned facilities in Minnesota and Nebraska.

The Dual Hydrogen Strategy

Here's why this project stands out from typical SAF developments. Instead of committing to a single hydrogen source, DG Fuels designed the facility to produce both types on-site, creating a built-in risk mitigation strategy.

The blue hydrogen portion includes an Air Separation Unit, Auto Thermal Reformer, and CO2 capture systems. The green hydrogen facilities rely on water electrolysis powered by renewable energy.

Why Louisiana Makes Sense

Louisiana has emerged as a magnet for clean fuel investments. The state offers established natural gas infrastructure, port access along the Mississippi River, and a skilled energy workforce.

The facility will process locally sourced agricultural waste, including sugarcane bagasse and timber byproducts. DG Fuels committed to purchasing approximately $120 million annually in sugar cane waste, creating direct value for local farmers.

Proven Technology, Major Partners

DG Fuels licensed Fischer-Tropsch CANS technology from Johnson Matthey and bp for SAF production. The company also partnered with NEXTCHEM for gasification technology capable of processing 1 million tonnes annually of locally sourced bagasse.

The combination creates drop-in SAF with lifecycle emissions reduced by up to 100% compared to conventional jet fuel. Delta Airlines signed on as the project's largest customer, and the company holds a partnership with Airbus.

Economic Ripple Effects

The project will generate an estimated $7.8 billion in total economic output for Louisiana. Construction will support an average of 10,426 jobs over four years with $2.5 billion in payroll, while operations will create 650 permanent positions averaging $72,000 annually.

Setting the Standard for Clean Fuel Production

The dual hydrogen approach isn't just clever engineering. It's a pragmatic response to real market conditions. Natural gas prices fluctuate, and renewable electricity costs vary by region and season. By building capacity for both, DG Fuels can optimize production based on whatever energy source offers the best economics at any given time.

Samsung E&A's broader strategy aligns with this vision. The company has been securing clean energy contracts globally, positioning this Louisiana project as their full-scale entry into the North American clean fuels market.

For an industry searching for ways to scale SAF production while managing risk, the DG Fuels model offers a template worth studying. It's not about choosing between blue and green hydrogen. It's about building systems flexible enough to use both, depending on what makes the most sense economically and environmentally.
