Carbon Clean and Samsung E&A, both of which maintain their U.S. headquarters in Houston, have formed a partnership to accelerate the global use of industrial carbon capture systems.

Carbon Clean provides industrial carbon capture technology. Samsung E&A offers engineering, construction and procurement services. The companies say their partnership will speed up industrial decarbonization and make carbon capture more accessible for sectors that face challenges in decarbonizing their operations.

Carbon Clean says its fully modular columnless carbon capture unit, known as CycloneCC, is up to 50 percent smaller than traditional units and each "train" can capture up to 100,000 tonnes of CO2 per year.

“Our partnership with Samsung E&A marks a major milestone in scaling industrial carbon capture,” Aniruddha Sharma, chair and CEO of Carbon Clean, said in a news release.

Hong Namkoong, CEO of Samsung E&A, added that the partnership with Carbon Clean will accelerate the global rollout of carbon capture systems that “are efficient, reliable, and ready for the energy transition.”

Carbon Clean and Samsung E&A had previously worked together on carbon capture projects for Aramco, an oil and gas giant, and Modec, a supplier of floating production systems for offshore oil and gas facilities. Aramco’s Americas headquarters is also in Houston, as is Modec’s U.S. headquarters.

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.

Houston carbon capture company signs MOU with PETRONAS

big deal

Carbon Clean announced a new partnership with PETRONAS CCS Solution, a subsidiary of PETRONAS, to collaborate and evaluate Carbon Clean’s carbon capture and storage technology.

The two companies will assess carbon capture technology by aiming to “identify synergies and explore future collaboration opportunities,” according to a news release.The primary focus of the MOU is Carbon Clean's CycloneCC tech, which can reduce the installed cost of carbon capture by up to 50 percent. Both companies will collaborate to develop how the modular technology can be used for post-combustion CO2 capture.

“PETRONAS has a pioneering approach to decarbonization, viewing carbon capture as a lever to transform its business,” Aniruddha Sharma, chair and CEO of Carbon Clean, says in the release. “It is turning the low-carbon energy transition into an opportunity to drive green growth. Carbon Clean is proud to support PETRONAS in achieving its net zero targets by providing a cost-effective approach to carbon capture.”

The modular design assists with easily installation and makes it more efficient to integrate with operations that are already up and running. The physical footprint of CycloneCC occupies up to 50 percent less space than conventional carbon capture solutions. The equipment itself is 10 times smaller and includes rotating packed bed (RPB) technology that uses centrifugal force to make carbon capture process run more efficiently.

“CycloneCC’s modular design enables companies to stagger their investment, adding units in line with their decarbonization goals,” Sharma said in a news release. “We are making carbon capture logistically viable and easy to scale.”

Carbon Clean also has partnered with AGRA Industries, as the biofuel industry could use Carbon Clean’s CaptureX technology. The United Kingdom-based company operates its U.S. headquarters in the Ion.

Carbon Clean’s other customers include companies in the cement, steel, refinery, and energy-to-waste sectors. Among the investors in Carbon Clean are Chevron, Samsung Ventures, Saudi Aramco Energy Ventures, and WAVE Equity Partners. Since it's founding in 2019, the company has raised $260 million in funding, according to data platform Tracxn.

Houston co. enters new carbon capture collaboration focused on biofuels industry

cleaning up

Carbon Clean, a carbon capture company whose North American headquarters is in Houston, has forged a deal with a contractor to build modular carbon capture containers for the agricultural sector.

The company, based in the United Kingdom, says its tentative partnership with Merrill, Wisconsin-based AGRA Industries should speed up adoption of Carbon Clean’s CaptureX technology in the biofuel industry.

Carbon Clean’s technology has been installed at 49 sites around the world. Eighty percent of the sites have prefabricated modular carbon-capture containers, reducing construction and installation time.

The partnership will enable customers to capture CO2 released during the biofuel fermentation stage, enabling the production of fuels with lower carbon-intensity ratings. This will improve the ability of biofuel producers to claim federal tax credits, Carbon Clean says.

“Carbon Clean’s collaboration with AGRA Industries is a win-win for biofuel producers. Customers will benefit from the expertise of a leading agricultural engineering specialist and our modularized, innovative carbon capture technology that is cost-effective and simple to install,” Aniruddha Sharma, chair and CEO of Carbon Clean, says in a news release.

Carbon Clean’s customers include companies in the cement, steel, refinery, and energy-to-waste sectors.

Among the investors in Carbon Clean, founded in 2019, are Chevron, Samsung Ventures, Saudi Aramco Energy Ventures, and WAVE Equity Partners. To date, the company has raised $260 million in funding, according to data platform Tracxn.

Clean energy founder shares key takeaways from CERAWeek 2024

guest column

Earlier this month, thousands converged on Houston for one of the world’s largest energy conferences – CERAWeek 2024. For five days global leaders, CEOs, oil and gas experts, and the industry’s top stakeholders gathered to provide insight, and discuss solutions, to some of the biggest questions on the future of energy.

Just this week, on the heels of the conference, it was hugely encouraging to see the U.S. Department of Energy (DOE) announce up to $6 billion for 33 projects across more than 20 states to decarbonize energy-intensive industries and reduce industrial greenhouse gas emissions. The announcement underscored the vitally important, and yet largely untapped role that industrial carbon capture must play in reaching the U.S.’s overall decarbonization goals. This must include significant point-source technology onsite at hard-to-abate industrial emitters like cement, metals and chemicals. The DOE announcement makes that priority clear, with the focus of the two largest grants for cement decarbonization projects going to carbon capture, each up to $500 million.

This was one of the major takeaways at this year’s CERAWeek: despite the success of the IRA, if we are to achieve the rapid scaling required to tackle emissions coming from hard-to-abate sectors, and now is the time to move rapidly into deployment, beginning with carbon capture demonstrations at industrial sites. Through our work with Chevron on the development of a carbon capture pilot for our CycloneCC technology on a gas turbine in San Joaquin Valley, California, we are proud to be doing exactly that.

While Carbon Clean has been active in the U.S. for several years, we chose to unveil our new Houston headquarters during last year’s CERAWeek, selecting the energy capital of the world for our U.S. home. With this increased focus on industrial decarbonization, the opportunities for carbon capture deployment in the U.S. – and more specifically Greater Houston – have significantly expanded. Since first opening the U.S. headquarters in Houston last year, we have grown our headcount by two-thirds and seen U.S. inquiries for our modular, point-source carbon capture solutions skyrocket by a further 59% (and this is after the initial leap in interest following the IRA’s passage).

Still, while a lot has been accomplished over the past year, we recognize that a lot more needs to be done to meet the country’s net zero targets, particularly in the space of industrial decarbonization. This was another takeaway at this year’s CERAWeek, a recognition that many industrial leaders have adopted ambitious net-zero goals but have no plans for implementation.

In conversations with many of this year’s conference attendees, one thing became abundantly clear: yes, the IRA was a breakthrough moment that provided key incentives for companies to enter the carbon capture space and develop the kinds of decarbonization technology that will reduce emissions. However, that only gets us half of the way there: we need to foster a market for the demand of clean industrial production, using the IRA as the vehicle to create that supply. Through the allocation of credits and increased pricing power, we can generate more demand from industrial emitters to embrace the kinds of technology that will enable them to reach net-zero.

Another critical next step: when it comes to adopting local industrial carbon capture projects, accelerate permitting by letting the states decide for themselves. The EPA’s recent decision to grant Louisiana the power to approve carbon capture projects could open the door to a wave of new project applications and additional states seeking the same authority.

If you want an example of a local economy poised to greatly benefit from expanded access to industrial carbon capture, look no further than Houston. With its energy expertise and local resources, Greater Houston is uniquely positioned to take full advantage of carbon capture’s promise, which will not only reduce the region’s emissions but grow jobs.

A recent study by the EFI Foundation, supported by Carbon Clean, identified Houston as an ideal location for a new coordinated regional approach to industrial carbon capture hubs. Previously, most studies on deployment focused on decarbonizing large emitters - the EFI report is focused on small-to-midsize emitters, as they account for 25 percent of America’s industrial emissions but are often overlooked given the cost and space barriers that have historically been barriers to the mass adoption of industrial carbon capture units.

Today, there are 311 facilities in the Houston cluster that fit the bill, representing 36.6 million metric tons of capturable CO2 emissions per year. Given that the region employs nearly a third of the nation’s jobs in oil and gas extraction alone, allowing multiple local emitters access to shared CO2 transport and storage would create a scalable solution at a lower cost. The business community should embrace the findings of this report, unlocking a key tool in combating local emissions, while also sustaining Houston’s workforce.

This year’s CERAWeek occurred during an inflexion point in the U.S.’s conversation around decarbonization. While a lot of progress is underway, it is imperative that energy leaders and the business community fully leverage industrial carbon capture technology if they are serious about reducing emissions at the source. Failure to do so recalls the aphorism by Benjamin Franklin: "Failing to plan is planning to fail.”

Carbon capture co. with Houston presence receives prestigious sustainability recognition

climatetech heroes

A United Kingdom-headquartered carbon capture business with a growing presence in Houston has received a distinguishing honor that recognizes climatetech leaders.

Carbon Clean, which has expanded to the United States by way of Houston, has received the Sustainable Markets Initiative 2023 Terra Carta Seal. The distinguishment recognizes global companies that are helping to create a nature-positive future for the climate. This is part of the Sustainable Markets Initiative’s larger mandate to help provide a framework to accelerate the transition to a sustainable future by placing the planet and people first.

“The Sustainable Markets Initiative’s Terra Carta Seal recognises those companies which are taking great strides in delivering real-world outcomes," Jennifer Jordan-Saifi, CEO of Sustainable Markets Initiative, says in the release. "As we stand on the eve of COP28, public, private sector, and philanthropic actors will come together at the inaugural Business and Philanthropy Climate Forum to bridge the gap between ambition and action. It isexamples exemplified by the 2023 Terra Carta Seal winners that are helping to inspire and lead the way.”

The Terra Carta Seal was launched in 2021 during COP26 by His Majesty King Charles III when he was the Prince of Wales. An international panel of experts from the environmental, business, political and philanthropic worlds chose 17 global companies for the honor.

“We are honored to be recognized by the Sustainable Markets Initiative for our contribution to the global transition to net zero, “ says Aniruddha Sharma, chair and CEO of Carbon Clean, in a news release. “Carbon Clean’s mission is simple: to deliver cost-effective, space-saving, modular carbon capture technology, enabling hard-to-abate industries to decarbonise at scale.”

Carbon Clean aims to revolutionize industrial carbon capture with its CycloneCC, which solves large barriers to widespread adoption of industrial carbon capture: cost and space.The technology of CycloneCC will be key in the company’s goal to achieve net zero by 2050.

Carbon Clean develops carbon capture technology for customers such as cement producers, steelmakers, refineries, and waste-to-energy plants. The company bills its offering as the “world’s smallest industrial carbon capture technology.” CycloneCC can reduce the cost of carbon capture by as much as 50 percent with a footprint that’s 50 percent smaller than traditional carbon capture units, according to Carbon Clean. The UK company established its Houston location this year.

Last month, CycloneCC was selected by ADNOC for a carbon capture project at Fertiglobe’s plant located in the Ruways Industrial Complex, Abu Dhabi. The project is the first deployment of a 10 tonnes per day CycloneCC industrial unit.

The new projects will include one wind and two solar projects in Texas.

“The continued growth of our relationship with Ares reflects the strength of ENGIE’s portfolio of assets and our track record of delivering, operating and financing growth in the U.S. despite challenging circumstances,” Dave Carroll, CEO and Chief Renewables Officer of ENGIE North America, said in a news release. “The addition of another 730 MW of generation to our existing relationship reflects the commitment both ENGIE and Ares have to meeting growing demand for power in the U.S. and our willingness to invest in meeting those needs.”

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada, and 52.7 gigawatts worldwide. The company is targeting 95 gigawatts by 2030.

ENGIE launched three new community solar farms in Illinois since December, including the 2.5-megawatt Harmony community solar farm in Lena and the Knox 2A and Knox 2B projects in Galesburg.

The company's 600-megawatt Swenson Ranch Solar project near Abilene, Texas, is expected to go online in 2027 and will provide power for Meta, the parent company of social media platform Facebook. Late last year, ENGIE also signed a nine-year renewable energy supply agreement with AstraZeneca to support the pharmaceutical company’s manufacturing operations from its 114-megawatt Tyson Nick Solar Project in Lamar County, Texas.

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.
