Samsung E&A Launches $2.6B Clean Ammonia Plant in Indiana

Samsung E&A officially broke ground on its Wabash Low-Carbon Ammonia Project on January 5, 2026. The plant is located in West Terre Haute, Indiana. Developed with Wabash Valley Resources, the facility will produce 500,000 metric tons of ammonia annually, per Samsung E&A's official announcement. It will also capture 1.67 million metric tons of CO2 each year. That scale places this among the largest CCS projects in U.S. history.

What Is the Wabash Low-Carbon Ammonia Project?

Samsung E&A is a South Korean engineering firm. It provides total solutions for the global energy industry. In October 2025, the company signed a KRW 680 billion contract with Wabash Valley Resources. That contract, worth approximately USD 475 million, covers engineering, procurement, and fabrication work. Construction is now underway, with a target completion date of 2029.

Wabash Valley Resources acquired a world-scale gasification plant in West Terre Haute in 2016. The site sat idle for nearly a decade before the company began its conversion. The plant transforms petroleum coke, a refinery byproduct, into low-carbon ammonia through gasification technology. The result is 500,000 metric tons of domestically produced clean ammonia per year.

Casale's proprietary N-LOOP process enables production of 1,630 metric tons of ammonia per day, according to Casale's project disclosures. Fertilizer plants globally account for approximately 2% of total CO2 emissions, according to industry data. The Wabash project embeds carbon capture directly into the ammonia production process to address that challenge at source.

How Is the Plant Capturing 1.67 Million Tons of CO2?

The facility is designed to capture 1.67 million metric tons of CO2 every year, per Samsung E&A's project filings. That is equivalent to removing more than 360,000 passenger vehicles from U.S. roads annually. This figure is based on the EPA's established benchmark of 4.6 metric tons of CO2 per passenger vehicle per year. The plant covers close to 100% of its total carbon output.

Captured CO2 will be stored approximately 7,000 feet underground. It will be injected into the Mount Simon Sandstone, a deep saline aquifer that sits beneath Indiana. That formation is part of the Illinois Basin, one of the most geologically stable carbon storage sites in North America.

Baker Hughes will manage subsurface operations using its CarbonEdge digital platform. This marks CarbonEdge's first commercial deployment anywhere in the world. Honeywell UOP is also a key technology partner for ammonia synthesis and carbon handling systems.

What Makes This a U.S.-Korea Clean Energy Milestone?

Both governments backed this project with committed capital. The U.S. DOE closed a USD 1.5 billion loan under its Energy Dominance Financing program in October 2025. South Korea's Ministry of Land, Infrastructure and Transport and its Ministry of Climate, Energy, and Environment are co-funding the project.

Korean private capital is also in the mix. Hanwha Asset Management and Korea Investment Real Asset Management Co. (KIRA) have both committed funds to Wabash. The January 5 groundbreaking ceremony at the Hay Adams Hotel in Washington, D.C. drew approximately 70 government and industry officials from both nations.

Samsung E&A plans to use digital transformation tools, AI, automation, and modular construction throughout the build. The company recently secured contracts for a SAF plant in Louisiana, a biodegradable plastics facility in the UAE, and LNG design work in Indonesia. The Wabash project is the centerpiece of its clean energy portfolio in North America.

What Does This Mean for America's Ammonia Future?

U.S. Energy Secretary Chris Wright has stated that America has long been dependent on foreign sources of fertilizer. The Wabash plant addresses that directly. It will deliver 500,000 metric tons of domestically produced, low-carbon ammonia each year to the Corn Belt, per Samsung E&A. Indiana's clean energy sector has steadily gained momentum, and this project is its highest-profile milestone.

The plant's 1.67 million metric ton CO2 capture capacity is equivalent to removing more than 360,000 vehicles from American roads annually, based on EPA benchmarks. That figure demonstrates what integrated, industrial-scale decarbonization looks like in practice. For U.S. farmers, it means a reliable domestic fertilizer supply with near-zero carbon intensity.

The IEA projects that global demand for low-emission hydrogen could reach 38 million metric tonnes by 2030. That is more than triple today's output levels. The project is backed by USD 2.6 billion in committed capital. It carries bilateral support from the U.S. and South Korea. The Wabash facility is on track to anchor industrial decarbonization across the American Midwest.
