TotalEnergies has begun the commercial operations of two utility-scale solar farms with integrated battery storage located in southeast Texas.

The two farms are located in Cottonwood and Danish Fields, which is TotalEnergies’ largest solar farm in the United States.

“The start-ups of Danish Fields and Cottonwood in the fast-growing ERCOT market showcase TotalEnergies’ ability to deliver competitive renewable electricity to support our clients’ decarbonization goals, as well as our own,” Olivier Jouny, senior vice president of renewables at TotalEnergies, says in a news release.

The new projects have a combined capacity of 1.2 gigawatts. They are part of a portfolio of renewable assets totaling 4 gigawatts in operation or under construction currently in Texas. Danish Fields holds a capacity of 720 megawatts peak and 1.4 million ground-mounted photovoltaic panels.

Cottonwood, with a capacity of 455 megawatts peak featuring over 847,000 ground-mounted photovoltaic panels, will also feature 225 megawatt hours of battery storage supplied by Saft. This is scheduled for commissioning in 2025. The electricity production is contracted under long-term PPAs indexed to “merchant prices through an upside-sharing mechanism with LyondellBasell and Saint-Gobain,” per thenews release. The deal is to help support the companies’ decarbonization efforts.

Seventy percent of Danish’s solar capacity has been contracted through long-term Corporate Power Purchase Agreements signed with Saint-Gobain, which feature an upside sharing mechanism indexed on merchant price. The other 30 percent is intended to support the decarbonization of TotalEnergies’ industrial plants in the Gulf Coast region. The projects will cover the electricity consumption of TotalEnergies’ industrial sites in Port Arthur and La Porte in Texas, and Carville in Louisiana, which include Myrtle Solar that was commissioned in 2023 and the under-construction Hill 1 solar farm.

In addition to the solar farms, TotalEnergies has also added 1.5 gigawatt of flexible power production capacity with three gas-fired power plants they acquired in Texas.

“Thanks to these projects, we are delighted to take another step in delivering our strategy across the entire value chain, from power generation to customer delivery, in order to achieve our profitability target of 12 (percent return on average capital employed) in our Integrated Power business,” Jouny adds in the release.

Talos Energy sells off low carbon arm to TotalEnergies in $148M deal

M&A moves

A Houston-based company is divesting its low-carbon subsidiary to TotalEnergies, which has its United States headquarters in Houston.

Talos Energy announced that it has entered into an agreement for the sale of its wholly owned subsidiary Talos Low Carbon Solutions LLC to TotalEnergies. The deal is for a purchase price of $125 million plus customary reimbursements, adjustments and retention of cash, which totals approximately $148 million.

According to a news release, Talos plans to use the proceeds from the sale to repay borrowings under its credit facility and for general corporate purposes. The sale includes Talos's entire carbon capture and sequestration business, which includes its three projects along the U.S. Gulf Coast with Bayou Bend CCS, Harvest Bend CCS, and Coastal Bend CCS.

There is an opportunity for additional future cash payments upon achievement of certain milestones at the Harvest Bend or Coastal Bend projects for Talos. More payments can be obtained also upon a sale of the aforementioned projects by TotalEnergies.

"Since TLCS's inception, we have successfully applied our energy expertise as an early mover aimed at developing decarbonization solutions along the U.S. Gulf Coast,” Talos President and CEO Timothy S. Duncan says in a news release. ”Strong market interest during our capital raise provided the strategic option to fully monetize the business to TotalEnergies, an established global leader in CCS development."

Talos Executive Vice President, Low Carbon Strategy and Chief Sustainability Officer Robin Fielder will continue to serve in her role for a transition period before leaving Talos.

"Robin and our entire CCS team did an outstanding job crystallizing value for Talos shareholders for a strong financial return," Duncan continues. "The transaction will further enable Talos to prioritize cash flow generation and optimal capital allocation in our core Upstream business. We are also continuing to explore business development and strategic M&A opportunities."

TotalEnergies is active in the Houston energy transition ecosystem and recently signed on as a partner at Greentown Houston. Last fall, the company also started commercial operations of its new solar farm, Myrtle Solar, just south of Houston.

up & running

A global energy corporation has a new solar farm online and operating just outside of Houston.

TotalEnergies (NYSE: TTE) has started commercial operations of its new solar farm, Myrtle Solar, just south of Houston. The farm has a capacity of 380 megawatts peak of solar production and 225 MWh of co-located batteries. Spread across the space — which is about the size of 1,800 football fields — are 705,000 solar panels producing enough electricity to power 70,000 homes.

Seventy percent of the power generated will be sourced for TotalEnergies' industrial plants in the U.S. Gulf Coast region, and the remaining 30 percent will be used by Kilroy Realty, a publicly traded real estate company, per a 15-year corporate power purchase agreement.

“We are very proud to start up Myrtle, TotalEnergies’ largest-to-date operated utility-scale solar farm with storage in the United States. This startup is another milestone in achieving our goal to build an integrated and profitable position in Texas, where ERCOT is the main electrical grid operator," Vincent Stoquart, senior vice president of renewables at TotalEnergies, says in the release. "Besides, the project will enable the Company to cover the power needs of some of its biggest U.S. industrial sites with electricity from a renewable source."

The farm is part of the company’s Go Green Project that is hoping to enable the company to cover its power needs by 2025, as well as curtail the Scope 1+2 emissions of its industrial sites in the Gulf Coast area, including Port Arthur and La Porte in Texas and Carville, Louisiana.

“Given the advantages that IRA tax exemptions are generating, we will continue to actively develop our 25 GW portfolio of projects in operation or development in the United States, to contribute to the Company’s global power generation target of more than 100 TWh by 2030,” Stoquart continues.

Myrtle Solar is also equipped with 114 high-tech Energy Storage Systems with a total capacity of 225 MWh. The technology was provided by TotalEnergies' affiliate Saft.

Engie to add 'precycling' agreements for forthcoming solar projects

reduce, reuse

Houston-based Engie North America has partnered with Arizona-based Solarcycle to recycle 1 million solar panels on forthcoming projects with a goal of achieving project circularity.

The collaboration allows Engie to incorporate "precycling" provisions into power purchase agreements made on 375 megawatts worth of projects in the Midwest, which are expected to be completed in the next few years, according to a news release from Engie.

Engie will use Solarcycle's advanced tracking capabilities to ensure that every panel on the selected projects is recycled once it reaches its end of life, and that the recovered materials are returned to the supply chain.

Additionally, all construction waste and system components for the selected projects will be recycled "to the maximum degree possible," according to Engie.

“We are delighted to bring this innovative approach to life. Our collaboration with Solarcycle demonstrates the shared commitment we have to the long-term sustainability of our industry,” Caroline Mead, SVP power marketing at ENGIE North America, said in the release.

Solarcyle, which repairs, refurbishes, reuses and recycles solar power systems, estimates that the collaboration and new provisions will help divert 48 million pounds of material from landfills and avoid 33,000 tons of carbon emissions.

“ENGIE’s precycling provision sets a new precedent for the utility-scale solar industry by proving that circular economy principles can be achieved without complex regulatory intervention and in a way that doesn’t require an up-front payment," Jesse Simons, co-founder and chief commercial officer at SOLARCYCLE, added in the release. "We’re happy to work creatively with leaders like ENGIE to support their commitment to circularity, domestic energy, and sustainability.”

Texas gets one step closer to CCUS permitting authority

The View From HETI

This month, the U.S. Environmental Protection Agency (EPA) announced its proposed approval of Texas request for permitting authority under the Safe Drinking Water Act (SDWA) for Class VI underground injection wells for carbon capture, utilization and storage (CCUS) in the state. The State of Texas already has permitting authority for Class I-V injection wells. Granting authority for Class VI wells recognizes that Texas is well positioned to protect its underground sources of drinking water while also advancing economic opportunity and energy security.

“In the Safe Drinking Water Act, Congress laid out a clear vision for delegating decision-making from EPA to states that have local expertise and understand their water resources, geology, communities, and opportunities for economic growth,” said EPA Administrator Lee Zeldin in a news release. “EPA is taking a key step to support cooperative federalism by proposing to approve Texas to permit Class VI wells in the state.”

The Greater Houston Partnership’s Houston Energy Transition Initiative (HETI) has supported efforts to bring CCUS to a broader commercial scale since the initiative’s inception. Earlier this year, HETI commissioned a “study of studies” by Texas A&M University’s Energy Institute and Mary K. O’Connor Process Safety Center on the operational history and academic literature of CCUS safety in the United States. The report revealed that with state and federal regulations as well as technical and engineering technologies available today, CCUS is safe and presents a very low risk of impacts to human life. This is useful research for stakeholders interested in learning more about CCUS.

“The U.S. EPA’s proposal to approve Texas’ application for Class VI well permitting authority is yet another example of Texas’ continued leadership in meeting the dual challenge of producing more energy with less emissions,” said Jane Stricker, Senior Vice President of Energy at the Greater Houston Partnership and Executive Director of the Houston Energy Transition Initiative. “We applaud the U.S. EPA and Texas Railroad Commission for their collaborative efforts to ensure the supply of safe, affordable and reliable energy, and we call on all stakeholders to voice their support for the application during the public comment period.”

The U.S. EPA has announced a public comment period that will include a virtual public hearing on July 24, 2025 from 5-8 pm and conclude on July 31, 2025.

Houston team’s discovery brings solid-state batteries closer to EV use

a better battery

A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.
