Houston energy technology company SLB announced a contract award by Petrobras to its OneSubsea joint venture for two subsea raw seawater injection systems to increase recovery from the prolific Búzios field in offshore Brazil.

The subsea RWI systems will work to increase the production of floating production storage and offloading (Petrobras FPSO) vessels that are currently bottlenecked in their water injection capacities.The RWI systems, once operational, can reduce greenhouse gas emissions per barrel of oil.

“As deepwater basins mature, we see more and more secondary recovery opportunities emerging,” Mads Hjelmeland, CEO of SLB OneSubsea, says in a news release. “Subsea raw seawater injection is a well-proven application with a strong business case that we think should become mainstream. By placing the system directly on the seabed, we free up space and reduce fuel needs for the FPSOs as well as lessen the power needs for the injection systems. It’s a win-win for Petrobras, and one that we are very excited about.”

SLB OneSubsea works to “optimize oil and gas production, decarbonize subsea operations, and unlock the large potential of subsea solutions to accelerate the energy transition,” per to the company.

SLB OneSubsea is contracted to provide two complete subsea RWI systems to support Petrobras’ FPSOs P-74 and P-75. They will consist of a subsea seawater injection pump, umbilical system and topside variable speed drive. In addition,the team will also provide technical support using AI-enabled Subsea Live services, which includes condition monitoring and access to domain experts.

“This contract will consolidate our solid local content presence in the country, contributed by the largest manufacturing plants and state-of-the-art subsea service facilities in Brazil,” Hjelmeland continues.

UH study finds Gulf Coast best positioned for emerging carbon removal technology

coastal impact

The Gulf Coast is an ideal spot for deploying a new ocean-based carbon removal technology that uses seawater to capture and store carbon dioxide, according to a new study from the University of Houston.

The study was led by UH Cullen College of Engineering Professor Mim Rahimi and published in Nature’s Communications Sustainability journal. Abdelrahman Refaie, a PhD student at UH, authored the paper. It aimed to develop a plan for implementing an electrochemical marine carbon dioxide removal (e-mCDR) technology that treats seawater to increase the ocean’s ability to absorb and store carbon dioxide from the air.

Currently, oceans absorb about 30 percent of human-produced carbon dioxide emissions each year, according to UH, making it a great natural resource for carbon removal.

The team at UH scouted and analyzed 38 coastal facilities across the U.S.—including power plants, desalination plants, and liquefied natural gas (LNG) terminals—before determining the Gulf Coast as an attractive option. The South Hub, or the Gulf Coast along Texas and Louisiana, ranked the top-performing area for the technology due to the industrial infrastructure, affordable electricity, hydrogen transportation and storage networks.

Other regions like California and the Northeast also scored well due to their clean energy mix and carbon removal potential, according to UH.

“The South hub has one of the highest diversity factors between power plants, desalination and LNG,” Refaie said in a news release. “That means if, logistically, down the road LNG is not open for this implementation, then we have another option in the area. It reduces the risk factor.”

UH says the findings show how companies could commercialize the technology, which could boost coastal economies.

“The question we had wasn’t technical, rather, it was logistical in regard to implementation down the road,” Rahimi said. “This would be a roadmap if a company or the government wants to utilize this technology.”

Rahimi aims to increase awareness about e-mCDR technology and its potential impact. He recently discussed the ocean-centric carbon removal work with members of Congress in March at the Carbon to Sea’s 2026 Hill Day.

“I think faculty at the University of Houston can do more of this kind of work,” Rahimi said in a separate release. “Meeting with Members of Congress gives us a chance to help policymakers better understand the science and engineering happening at our university. That kind of engagement is an important part of moving new technologies forward. It also shows how the work we do on campus can have a real impact on communities beyond the university.”

Japanese company plans $357M solar manufacturing plant in Houston area

coming soon

Japanese solar manufacturing company TOYO Co. Ltd. plans to invest $357 million to bring a 1.5-gigwatt solar cell manufacturing facility to the Houston area.

TOYO’s latest state-of-the-art facility will be co-located at its existing solar module site in Humble, according to a news release from the company. It will produce heterojunction (HJT) solar cells, which are known to be more durable and efficient with a higher heat threshold.

TOYO reports that the new facility will create 400 full-time manufacturing jobs. The project is expected to be completed in 20 months, which includes an initial pilot production.

"Expanding into domestic cell manufacturing is the natural next step in our commitment to creating an integrated onshore solar supply chain from polysilicon to panels," Takahiko Onozuka, chairman and CEO of TOYO, said in the news release. "Co-locating 1.5 GW of HJT cell capacity at our Houston module site significantly optimizes our capital allocation and infrastructure spend.”

TOYO entered the Houston market in 2024 through its acquisition of a majority stake in Solar Plus Technology Texas LLC.

Earlier this year, it began producing solar modules at its 567,140-square-foot plant in Lovett Industrial’s Nexus North Logistics Park. At the time, the company said it planned to expand manufacturing capacity to 6.5 gigawatts.

"The new cell plant reflects TOYO's long-term strategy to build a fully FEOC-compliant domestic manufacturing platform focused on serving the needs of the U.S. utility-scale solar market," Rhone Resch, TOYO's chief strategy officer, added in the release. "By producing premium solar products in the United States, we will be well positioned to meet the market's evolving domestic content requirements while strengthening supply chain security and reliability. Looking ahead, we believe HJT is the optimal technology platform for integrating next-generation perovskite solar cells, which we expect will drive the next major advancement in solar conversion efficiency and support TOYO's long-term technology roadmap.”
