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.

Houston scientists unveil faster, low-energy method to recycle lithium-ion batteries

Battery breakthrough

Rice University researchers have uncovered a more energy-efficient and faster way to recycle critical minerals from used lithium-ion batteries.

Traditional methods rely on high heat, long processing times and harsh chemicals to recover a small fraction of critical materials from batteries used in everything from smartphones to electric vehicles. However, the team from Rice's Department of Materials Science and Nanoengineering developed a process that uses a water-based solution containing amino chlorides to extract more metals in less time

The team published the findings in a recent edition of the scientific journal Small.

Simon King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute, served as first author of the study. He worked with corresponding authors Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Sohini Bhattacharyya, a research scientist in Ajayan’s lab.

By using a hydroxylammonium chloride (HACI) solution, the team achieved roughly 65 percent extraction of key battery metals in just one minute at room temperature, according to the study. The efficiencies grew to roughly 75 percent for several metals under longer processing times.

“We were surprised by just how fast the reaction occurs, especially without the involvement of high temperatures,” King said in a news release. “Within the first minute, we’re already seeing the majority of the metal extraction take place.”

By not requiring high temperatures or long reaction times, Rice predicts the process could have a major impact on cost and the environmental impact of lithium battery recycling. Additionally, the water-based HACI solution makes waste handling easier and lowers certain environmental risks.

In addition to extracting the materials, the team went on to demonstrate that the recovered metals could be recycled and reprocessed into new battery materials.

“A big advantage of this system is that it works under relatively mild conditions,” Ajayan added in the release. “That opens the door to more sustainable and scalable recycling technologies.”
