A clean energy developer and operator of solar and energy storage assets has announced the completion and commercial operation of a Houston-area farm that will power 15,000 homes a year.

Recurrent Energy's Liberty Solar project outside of Houston has powered on and will expand solar energy capacity in the Midcontinent Independent System Operator market. Recurrent Energy is an Austin-based a subsidiary of Canadian Solar.

“Projects like Liberty Solar are instrumental to meeting the soaring demand for electricity in Texas,” Executive Director of Texas Solar Power Association Mark Stover says in a news release. "We commend Recurrent Energy for pushing through the development process and working with corporate buyers to deliver new, predictable, clean power to the MISO region of Texas.”

Liberty Solar is in Liberty County, which is about 50 miles northeast of Houston and will be a 134 megawatt solar project. Customers include Autodesk Inc., Biogen Inc., EMD Electronics (the U.S. and Canada electronics business of Merck KGaA, Darmstadt, Germany), and Wayfair Inc.

“Investment in additional renewable capacity on the grid is essential to delivering more sustainable outcomes, and we believe that the Liberty Solar project will help make renewable energy more accessible in North America,” Joe Speicher, chief sustainability officer at Autodesk, adds in tje release. “Autodesk is committed to 100% renewable energy sourcing for our facilities, cloud services and hybrid workforce, and we are committed to leveraging our climate commitments to drive transformational change in our energy generation and deployment.”

Recurrent Energy celebrated the project by welcoming customers at Liberty Solar on October 23 for a guided tour and ribbon cutting ceremony.

“Liberty Solar is a fantastic project that expands Recurrent Energy’s project ownership in MISO,” Ismael Guerrero, CEO of Recurrent Energy, says in the release. “We are thrilled to complete this project on time and on budget in support of the renewable energy goals of our customers.”

Last year, Recurrent Energy scored $200 million in financing for the project, including $120 million in financing through Rabobank, Nord LB, and U.S. Bank in the form of construction debt, a letter-of-credit facility, and a term facility. In addition, U.S. Bancorp Impact Finance, a subsidiary of U.S. Bank, is providing $80 million in tax equity.

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”
