Just as the data center industry thrives on electricity, the hydrogen industry thrives on water.

A new study from researchers at the University of Texas at Austin found that by 2050, new hydrogen production facilities could account for 2 percent to nearly 7 percent of water demand in the state. The impact could be especially dramatic along the Gulf Coast, where most of the state’s hydrogen production facilities are already built or are being planned.

The research was published in the journal Sustainability.

The study reported that "most existing and proposed hydrogen production infrastructures are within projected water-strained cities and counties, such as Houston in Harris County and Corpus Christi in Nueces County."

Compared with municipal water supplies or irrigation systems, the hydrogen industry’s demand for water is comparatively small, the study’s lead author, Ning Lin, an energy economist at UT’s Bureau of Economic Geology, said in a news release. But hydrogen-fueled demand could strain communities that already are grappling with current and future water shortages.

“Where you put a project can make a huge difference locally,” Lin says. “With multiple hydrogen facilities planned in water-stressed Gulf Coast counties, this study highlights the urgent need for integrated water and energy planning and provides a solid foundation to help policymakers, industry, and communities make informed decisions about hydrogen and water management.”

To forecast water demand, Lin and her colleagues crunched data from a 2024 National Petroleum Council study that estimated the regional hydrogen demand from 2030 to 2050 based on two energy policy scenarios.

As part of the study, researchers reviewed water use and water quality for various hydrogen production methods that affect whether water remaining from production can be recycled.

“In order to plan for water needs, somebody has to figure out what those future demands might look like, and this paper puts some numbers to (it) that, I think, will be very helpful,” Robert Mace, executive director of the Meadows Center for Water and the Environment at Texas State University, who was not part of the study, added in the release.

Aramco partners to demonstrate compact carbon capture technology for gas turbines

dream team

Integrated energy and chemicals company Aramco has signed a collaboration agreement with Carbon Clean and SAMSUNG E&A in an effort to showcase new carbon capture technology.

The technology demonstration will be used to deploy Carbon Clean’s novel CycloneCC technology to capture CO2 from natural gas turbine exhaust streams containing approximately 4 percent CO2, according to Aramco.

Carbon Clean, which U.S. headquarters are located in Houston at the Ion, boasts technology that has captured nearly two million tons of carbon dioxide at almost 50 sites around the world. Aramco’s U.S. headquarters is also in Houston.

“The potential for CycloneCC in the US and Houston area is huge,” Aniruddha Sharma, chair and CEO of Carbon Clean, previously shared with EnergyCapital. “It is optimised for low to medium scale industrial emitters and recent Rice University research on the US Gulf Coast, for example, found that it is well suited to 73 percent of Gulf Coast emitters.”

The modular CycloneCC unit has a 50 percent smaller footprint compared to conventional carbon capture processes. The CycloneCC technology is estimated to reduce the total installed cost of carbon capture systems by up to 50 percent compared to conventional systems if successful. The goal is to also maintain process efficiency even at low CO2 concentrations. CycloneCC’s performance is achieved through two process intensification technologies, rotating packed beds (RPBs) and Carbon Clean’s proprietary APBS-CDRMax solvent.

“Its compact, modular design should be easily integrated with gas turbines, delivering high performance carbon capture in an industrial setting where space is typically limited,” Sharma says in a news release.

The engineering, procurement and construction of the plant will be done by SAMSUNG E&A .The unit will be installed on the sales gas compressor turbine exhaust gas stack,which can provide performance data under real-world conditions.

“Aramco and Samsung Ventures are investors in Carbon Clean, so we’re proud to deepen our relationship through this partnership,” Sharma adds. “This first-of-a-kind deployment capturing very low concentrations of CO2 is a key milestone in scaling up and commercializing CycloneCC.”

In September, Carbon Clean also announced a deal with PETRONAS CCS Solution to collaborate and evaluate Carbon Clean’s carbon capture and storage technology with Carbon Clean's CycloneCC tech. Last year, Abu Dhabi National Oil Co. (ADNOC) selected Carbon Clean for a carbon capture project in Abu Dhabi.

ExxonMobil signs biggest offshore CCS lease in the U.S.

big deal

Spring-based ExxonMobil continues to ramp up its carbon capture and storage business with a new offshore lease and a new CCS customer.

On October 10, ExxonMobil announced it had signed the biggest offshore carbon dioxide storage lease in the U.S. ExxonMobil says the more than 271,000-acre site, being leased from the Texas General Land Office, complements the onshore CO2 storage portfolio that it’s assembling.

“This is yet another sign of our commitment to CCS and the strides we’ve been able to make,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release.

The offshore site is adjacent to a CO2 pipeline network that ExxonMobil acquired in 2023 with its $4.9 billion purchase of Plano-based Denbury Resources.

Ammann told Forbes that when it comes to available acreage in the Gulf Coast, this site is “the largest and most attractive from a geological point of view.”

The initial customer for the newly purchased site will be Northbrook, Illinois-based CF Industries, Forbes reported.

This summer, ExxonMobil sealed a deal to remove up to 500,000 metric tons of CO2 each year from CF’s nitrogen plant in Yazoo City, Mississippi. CF has earmarked about $100 million to build a CO2 dehydration and compression unit at the plant.

A couple of days before the lease announcement, Ammann said in a LinkedIn post that ExxonMobil had agreed to transport and annually store up to 1.2 metric tons of CO2 from the $1.6 billion New Generation Gas Gathering (NG3) pipeline project in Louisiana. Houston-based Momentum Midstream is developing NG3, which will collect and treat natural gas produced in Texas and Louisiana and deliver it to Gulf Coast markets.

This is ExxonMobil’s first CCS deal with a natural gas processor and fifth CCS deal agreement overall. To date, ExxonMobil has contracts in place for storage of up to 6.7 metric tons of CO2 per year.

“I’m proud that even more industries are choosing our #CCS solutions to meet their emissions reduction goals,” Ammann wrote on LinkedIn.

ExxonMobil says it operates the largest CO2 pipeline network in the U.S.

“The most fundamental thing we’re focused on is making sure the CO2 is stored safely and securely,” Ammann told Forbes in addressing fears that captured CO2 could seep back into the atmosphere.

Dockworkers' union suspends strike until new year to allow time to negotiate new contract

pressing pause

Some 45,000 dockworkers at East and Gulf coast ports are returning to work after their union reached a deal to suspend a strike that could have caused shortages and higher prices if it had dragged on.

The International Longshoremen’s Association is suspending its three-day strike until Jan. 15 to provide time to negotiate a new contract. The union and the U.S. Maritime Alliance, which represents ports and shipping companies, said in a joint statement that they have reached a tentative agreement on wages.

A person briefed on the agreement said the ports sweetened their wage offer from about 50% over six years to 62%. The person didn’t want to be identified because the agreement is tentative. Any wage increase would have to be approved by union members as part of the ratification of a final contract.

Talks now turn to the automation of ports, which the unions says will lead to fewer jobs, and other sticking points.

Industry analysts have said that for every day of a port strike it takes four to six days to recover. But they said a short strike of a few days probably wouldn’t gum up the supply chain too badly.

The settlement pushes the strike and any potential shortages past the November presidential election, eliminating a potential liability for Vice President Kamala Harris, the Democratic nominee. It’s also a big plus for the Biden-Harris administration, which has billed itself as the most union-friendly in American history. Shortages could have driven up prices and reignited inflation.

The union went on strike early Tuesday after its contract expired in a dispute over pay and the automation of tasks at 36 ports stretching from Maine to Texas. The strike came at the peak of the holiday season at the ports, which handle about half the cargo from ships coming into and out of the United States.

Most retailers had stocked up or shipped items early in anticipation of the strike.

“With the grace of God, and the goodwill of neighbors, it’s gonna hold,” President Joe Biden told reporters Thursday night after the agreement.

In a statement later, Biden applauded both sides “for acting patriotically to reopen our ports and ensure the availability of critical supplies for Hurricane Helene recovery and rebuilding.”

Biden said that collective bargaining is “critical to building a stronger economy from the middle out and the bottom up.”

The union's membership won't need to vote on the temporary suspension of the strike. Until Jan. 15, the workers will be covered under the old contract, which expired on Sept. 30.

The union had been demanding a 77% raise over six years, plus a complete ban on the use of automation at the ports, which members see as a threat to their jobs. Both sides also have been apart on the issues of pension contributions and the distribution of royalties paid on containers that are moved by workers.

Thomas Kohler, who teaches labor and employment law at Boston College, said the agreement to halt the strike means that the two sides are close to a final deal.

“I’m sure that if they weren’t going anywhere they wouldn’t have suspended (the strike),” he said. “They’ve got wages. They’ll work out the language on automation, and I’m sure that what this really means is it gives the parties time to sit down and get exactly the language they can both live with.”

Kohler said the surprise end to the strike may catch railroads with cars, engines and crews out of position. But railroads are likely to work quickly to fix that.

Just before the strike had begun, the Maritime Alliance said both sides had moved off their original wage offers, a tentative sign of progress.

Thursday's deal came after Biden administration officials met with foreign-owned shipping companies before dawn on Zoom, according to a person briefed on the day's events who asked not to be identified because the talks were private. The White House wanted to increase pressure to settle, emphasizing the responsibility to reopen the ports to help with recovery from Hurricane Helene, the person said.

Acting Labor Secretary Julie Su told them she could get the union to the bargaining table to extend the contract if the carriers made a higher wage offer. Chief of Staff Jeff Zients told the carriers they had to make an offer by the end of the day so a manmade strike wouldn't worsen a natural disaster, the person said.

By midday the Maritime Alliance members agreed to a large increase, bringing about the agreement, according to the person.

Longshoremen from Maine to Texas appear likely to go on strike, seaport CEO says

workers docked

The chief executive over Georgia's two booming seaports said Tuesday that a strike next week by dockworkers across the U.S. East and Gulf coasts appears likely, though he's hopeful the resulting shutdown would last only a few days.

“We should probably expect there to be a work stoppage and we shouldn’t get surprised if there is one," Griff Lynch, CEO of the Georgia Ports Authority, told The Associated Press in an interview. "The question is: How long?”

U.S. ports from Maine to Texas are preparing for a potential shutdown in a week, when the union representing 45,000 dockworkers in that region has threatened to strike starting Oct. 1. That's when the contract expires between the International Longshoremen's Association and the United States Maritime Alliance, which represents the ports. Negotiations on a new contract halted in June.

A strike would shut down 36 ports that handle roughly half the nations' cargo from ships. Lynch oversees two of the busiest in Georgia. The Port of Savannah ranks No. 4 in the U.S. for container cargo that includes retail goods ranging from consumer electronics to frozen chickens. The Port of Brunswick is America's second-busiest for automobiles.

Lynch said he's holding out hope that a strike can be averted, though he added: “The stark reality is they are not talking right now." Represented by the maritime alliance, the Georgia Ports Authority has no direct role in negotiating.

As for how long a strike might last, “no one really knows for sure,” said Lynch, Georgia's top ports executive since 2016 and a three-decade veteran of the maritime industry. “I would think we should expect four to five days, and hopefully not beyond that.”

Businesses have been preparing for a potential strike for months, importing extra inventory to fill their warehouses. Lynch said that's one reason container volumes in Savannah increased 13.7% in July and August compared to the same period a year ago.

Georgia dockworkers are putting in extra hours trying to ensure ships get unloaded and return to sea before next Tuesday's deadline. Truck gates at the Port of Savannah, normally closed on Sundays, will be open throughout this weekend.

At the Georgia Ports Authority's monthly board meeting Tuesday, Lynch praised the roughly 2,000 union workers responsible for loading and unloading ships in Savannah and Brunswick, saying “they have done great work” ahead of a possible strike. He said the ports would keep operating until the last minute.

“We’re seeing phenomenal productivity out of them right now," he said. "You wouldn’t know this was going to happen if you hadn’t been told.”

There hasn't been a national longshoremen’s strike in the U.S. since 1977. Experts say a strike of even a few weeks probably wouldn't result in any major shortages of retail goods, though it would still cause disruptions as shippers reroute cargo to West Coast ports. Lynch and other experts say every day of a port strike could take up to a week to clear up once union workers return to their jobs.

A prolonged strike would almost certainly hurt the U.S. economy.

The maritime alliance said Monday it has been contacted by the U.S. Labor Department and is open to working with federal mediators. The union's president, Harold Daggett, said in a statement his members are ready to strike over what he called an unacceptable “low-ball wage package.”

“We’re hopeful that they’ll get it worked out," said Kent Fountain, the Georgia Ports Authority's board chairman. “But if not, we’re going to do everything we can to make it as seamless as possible and as easy as it could possibly be on our customers and team members.”

First-of-its-kind, DOE-backed plant coming to Houston area

Carbon capture and storage

The first full-scale implementation of carbon capture and storage technology at a natural gas combined cycle power plant in the U.S. is coming to Baytown.

Houston power company Calpine announced plans to build the Baytown Carbon Capture and Storage Project (Baytown CCS Project), which is a carbon capture demonstration facility that aims to capture carbon dioxide from the Baytown Energy Center (BEC). The BEC is a natural gas combined-cycle power plant in Baytown.

The Department of Energy recently announced that it will share in the cost of up to $270 million on the Baytown project. The DOE revealed more details on the project on its website.

The project aims to utilize Shell’s CANSOLV point-source technology to capture up to 2 million metric tons of CO2 per year, which is equivalent to the annual emissions of nearly 450,000 gasoline-powered cars. In addition, the project plans to sequester the CO2 in saline storage sites on the Gulf Coast.

Evaluating the use of greywater cooling to minimize freshwater consumption by reusing wastewater, the project’s primary power and steam off-taker Covestro hopes to prove “technologies that showcase the benefits of decarbonized process heat and electricity in the industrial sector,” according to a news release.

In December of 2023, Calpine was selected by the Department of Energy's Office of Clean Energy Demonstrations for a cost-sharing agreement for a commercial-scale carbon capture and storage project.

"This is a critical step towards decarbonizing Calpine’s facility, which is located on our Covestro Baytown site,” Demetri Zervoudis, Covestro head of operations for North America and Baytown site general manager, said in a previous news release. “Carbon capture and storage technology is an important tool for the chemical industry to reduce carbon emissions, and it is encouraging to see Calpine at the forefront of this transition.”

The Baytown Decarbonization Project was developed collaboratively with local stakeholders in East Houston. According to the company, the project has already incorporated community feedback into the project designs to reduce non-CO2 air pollutants and minimize the usage of freshwater. The company estimates creating 22-26 permanent jobs and 1,500,000 hours of construction jobs and has partnerships with minority-serving institutions.

“Carbon capture is an important technology for decarbonizing the electricity sector and the economy,” Thad Hill, CEO of Calpine Corp said in 2023 when the DOE decided to work with the CSS program. “Calpine is very grateful for the commitment and support for the project by our stakeholders.”

8 Houston energy companies land on Time's top greentech list for 2025

top honor

The accolades keep rolling in for Houston-based Fervo Energy, a producer of geothermal power.

Fervo lands at No. 6 on Time magazine and Statista’s new list of America’s Top GreenTech Companies of 2025. The ranking recognizes sustainability-focused companies based on factors such as impact, financial strength, and innovation.

Time notes that Fervo broke ground in 2023 in Utah on what the company claims will be the world’s largest geothermal plant. The plant is scheduled to start supplying carbon-free electricity to the grid next year and to reach its 400-megawatt capacity in three years.

“Technologies like this only make a difference if we deploy them at large-scale in a way that can reduce carbon emissions and increase the reliability of the grid,” Fervo CEO Tim Latimer told Time in 2023.

The startup was named North American Company of the Year by research and consulting firm Cleantech Group for 2025. Fervo topped the Global Cleantech 100, Cleantech Group’s annual list of the world’s most innovative and promising cleantech companies.

Last year, Fervo also made Time’s list of the 200 Best Inventions of 2024. Fervo was recognized in the green energy category for its FervoFlex geothermal power system.

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. The startup’s valuation is estimated at $1.4 billion. According to PitchBook data, the company raised $634 million in the fourth quarter of 2024.

In all, eight Houston-area companies appear among the top 250 greentech companies ranked by Time and Statista. Other than Fervo, they are:

  • No. 43 Lancium Technologies, an energy storage and distribution company
  • No. 50 Solugen, a producer of sustainable chemicals.
  • No. 56 Quaise Energy, which specializes in terawatt-scale geothermal power.
  • No. 129 Plus Power, a developer, owner and operator of battery storage projects.
  • No. 218 Dream Harvest, which promotes sustainable vertical farming.
  • No. 225 Cemvita, which uses synthetic biology to convert carbon emissions into bio-based chemicals.
  • No. 226 Syzygy Plasmonics, which decarbonizes chemical production.
Vermont-based BETA Technologies claimed the No. 1 spot. The company manufactures electric aircraft.
