Woodside Energy has announced its acquiring a Beaumont, Texas, clean ammonia project that's slated to deliver its first ammonia by 2025 and lower carbon ammonia by 2026.

The agreement is for Woodside to acquire 100 percent of OCI Clean Ammonia Holding and its lower carbon ammonia project in Beaumont in an all-cash deal of approximately $2.35 billion. According to Woodside CEO Meg O’Neill, the acquisition positions Woodside as an early mover in clean ammonia within the energy transition.

“This transaction positions Woodside in the growing lower carbon ammonia market," O’Neill says in a news release. "The potential applications for lower carbon ammonia are in power generation, marine fuels and as an industrial feedstock, as it displaces higher-emitting fuels.

“Global ammonia demand is forecast to double by 2050, with lower carbon ammonia making up nearly two-thirds of total demand," she continues. “This Project exceeds our capital allocation framework targets for new energy projects. Both phases are expected to achieve an internal rate of return above 10 percent and payback of less than 10 years."

OCI broke ground on the project in 2022. It's reportedly the world’s first ammonia plant paired with auto thermal reforming with over 95 percent carbon dioxide capture.

Phase 1 of the project will have a capacity of 1.1 million tonnes per annum and is currently under construction. The first ammonia production will be derived from natural gas and is slated for 2025, with lower carbon ammonia production — derived from natural gas paired with carbon sequestration — is expected in in 2026 following commencement of CCS operations

According to the release, Phase 2 will have the capacity to abate 3.2 million tonnes per annum CO2-e, "or over 60 percent of our Scope 3 abatement target,” O’Neill explains.

Linde will source the nitrogen and lower carbon hydrogen feedstock from its feedstock facility, which is currently under construction with a targeted completion in early 2026. In the meantime, early supply of feedstock for the project will come from various suppliers including Linde. Per the release, CCS services will be provided to Linde by ExxonMobil and are expected to be available in 2026.

ExxonMobil breaks ground on Texas carbon dioxide storage project

digging in

ExxonMobil announced this month that it has officially broken ground on a groundbreaking carbon dioxide storage site.

According to a release from the company, a new rig is currently being used to gather information about an underground site in Southeast Texas. The rig stands 225 feet tall, but more importantly extends 8,000 feet below the subsurface to investigate if the site is a safe place to store carbon underground.

“Everyone’s excited about this appraisal well because we’re literally breaking ground on a new chapter of our work to help reduce industrial emissions,” Joe Colletti, who oversees carbon capture and storage development along the Gulf Coast for Exxon, says in a statement.

Exxon plans to move the rig to other sites in the Gulf Coast in the future for clients Nucor Corp., CF Industries and Linde.

In the last year, Exxon has made agreements with these regional companies to store carbon captured from their operations.

  • Exxon agreed to transport and permanently store up to 2.2 million metric tons of carbon dioxide each year from Linde’s hydrogen production facility in Beaumont, Texas when it launches in 2025.
  • Exxon agreed to store up to 2 million metric tons per year of CO2 captured from CF Industries’ ammonia plant in Donaldsonville, Louisiana, starting in 2025.
  • Exxon agreed to capture, transport and store up to 800,000 metric tons per year of CO2 from Nucor’s direct reduced iron manufacturing site in Convent, Louisiana starting in 2026.

Together, the three agreements represent a total of 5 million metric tons per year that Exxon plans to transport and store for third-party customers.

“Our agreement with Nucor is the latest example of how we’re delivering on our mission to help accelerate the world's path to net zero and build a compelling new business,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a statement over the summer. “Momentum is building as customers recognize our ability to solve emission challenges at scale.”

In addition to the carbon storage agreements, the energy giant also completed the acquisition of Denbury Inc. this month in an all-stock transaction valued at $4.9 billion. The deal adds more than 1,300 miles, including nearly 925 miles of CO2 pipelines in Louisiana, Texas and Mississippi to Exxon's CO2 pipeline network.

The deal was first announced this summer.

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.
