Houston-based ExxonMobil and Rice University announced a master research agreement this week to collaborate on research initiatives on sustainable energy efforts and solutions. The agreement includes one project that’s underway and more that are expected to launch this year.

“Our commitment to science and engineering, combined with Rice’s exceptional resources for research and innovation, will drive solutions to help meet growing energy demand,” Mike Zamora, president of ExxonMobil Technology and Engineering Co., said in a news release. “We’re thrilled to work together with Rice.”

Rice and Exxon will aim to develop “systematic and comprehensive solutions” to support the global energy transition, according to Rice. The university will pull from the university’s prowess in materials science, polymers and catalysts, high-performance computing and applied mathematics.

“Our agreement with ExxonMobil highlights Rice’s ability to bring together diverse expertise to create lasting solutions,” Ramamoorthy Ramesh, executive vice president for research at Rice, said in the release. “This collaboration allows us to tackle key challenges in energy, water and resource sustainability by harnessing the power of an interdisciplinary systems approach.”

The first research project under the agreement focuses on developing advanced technologies to treat desalinated produced water from oil and gas operations for potential reuse. It's being led by Qilin Li, professor of civil and environmental engineering at Rice and co-director of the Nanosystems Engineering Research Center for Nanotechnology-Enabled Water Treatment (NEWT) Center.

Li’s research employs electrochemical advanced oxidation processes to remove harmful organic compounds and ammonia-nitrogen, aiming to make the water safe for applications such as agriculture, wildlife and industrial processes. Additionally, the project explores recovering ammonia and producing hydrogen, contributing to sustainable resource management.

Additional projects under the agreement with Exxon are set to launch in the coming months and years, according to Rice.

Houston-based ‘grid in a box’ provider Branch Energy raises $33M

fresh funding

Houston-based startup Branch Energy, which offers a self-contained “grid in a box,” has collected $33 million in a Series B round.

Piva Capital and Clean Energy Ventures led the round, according to a news release. Active Impact Investments, Whitecap Venture Partners, Prelude Ventures, Zero Infinity Partners and Inovia Capital also contributed to the round.

In 2024, Branch raised $10.8 million in an oversubscribed Series A round.

Branch’s business model

Branch, which launched in 2021, says its proprietary Arc “grid in a box” contains everything needed to store and supply electricity. A container about the size of a parking space holds an industrial-grade battery, grid connection equipment, cooling capabilities, autonomous controls and cloud-based management software.

The startup installs Arc systems at warehouses, hotels, factories, stores and other commercial properties. Each system arrives on a flatbed truck and can be online within two days, Branch says.

Under Branch’s business model, a property owner avoids upfront payment for an Arc system.

Aside from equipping a host business with an Arc system, Branch serves as the business’ power provider. The startup says it guarantees savings on the host’s energy bills and delivers backup power during outages.

Branch generates revenue by sending the battery’s stored power to the grid or to customers like hyperscale data centers. It also benefits by shifting energy from low-cost periods at night to high-cost periods during daily power peaks.

The startup handles permitting, installation, insurance and operations for each Arc system. The host provides a parking-lot-sized plot of land for the system.

Alex Ince-Cushman, co-founder and CEO of Branch, says the startup’s “grid in a box” can quickly meet the substantial power requirements of hyperscale data centers.

“We can do it on the timeline of a delivery, not a construction project. Our customers don’t lift a finger, don’t pay a dime and get guaranteed savings,” Ince-Cushman said in the release.

Entering the Illinois market

Branch already operates in Texas and is entering the Illinois market.

PJM, which operates Illinois’ power grid, recently paved the way for major energy users like data centers to connect to the grid sooner when they rely on their own electricity generation. PJM’s territory covers roughly 1.2 million commercial buildings and represents 20 percent of U.S. power demand, according to Branch.

“Grids around the country need the distributed capacity that [the Arc] system can supply, especially in states with fast-growing power demand like Texas and Illinois,” Lee Larson, principal at Piva Capital added in the release.

To keep up with that demand, Branch plans to build tens of thousands of Arc systems in the U.S.

A multibillion-dollar company in the making?

Daniel Goldman, co-founder and managing partner of Clean Energy Ventures, said Branch holds the potential to become a multibillion-dollar competitor in the emerging market for distributed power.

“With utility-scale generation and storage challenged by interconnect and siting constraints, behind-the-meter commercial, and industrial storage sites have become the ultimate market opportunity with ease of interconnect, ability to combine distributed AI data centers, and identifiable savings in rapidly growing markets,” Goldman said.

Kanin Energy raises up to $100M for waste-heat-to-power projects

fresh funding

Kanin Energy, a member of the Greentown Labs climatech and energy incubator in Houston, recently raised as much as $100 million in capital to grow its energy-as-a-service platform.

S2G Investments led a round of up to $50 million, and the Canada Growth Fund chipped in an additional $50 million. The money will primarily support Kanin’s development and operation of waste-heat-to-power projects.

Kanin—founded in 2020 in Calgary, Alberta, Canada—builds and runs onsite power assets for large-scale energy users. The startup says its energy-as-a-service offering lowers power costs, boosts power reliability and decreases emissions.

The company operates a waste-heat-to-power project at Ohio’s University of Dayton. The project supplies zero-emission electricity.

Kanin has a pipeline of projects totaling about 50 megawatts of capacity. This includes a waste-heat-to-power plant at the Phillips 66 Mewbourn gas-processing plant near Greeley, Colorado.

“Kanin was built on the belief that industrial facilities already hold the solution to their own energy challenges, they just need the right partner to execute,” Janice Tran, CEO of Kanin, who is based in Houston, said in a release. “At a time when power costs continue to rise, [our] solutions are an important tool for our industrial customers to manage their costs, operations, and emissions.”

Marisa Sweeney, principal at S2G, says waste heat is a largely underused resource for lowering power costs, alleviating grid congestion and improving power reliability.

The waste-heat-to-power process captures thermal energy from industrial activities and converts it to electricity. This happens without using extra fuel or generating more emissions.

Kanin says up to 58 percent of energy consumed by industrial processes is lost as waste heat. This heat winds up in the atmosphere at thousands of facilities in North America, including oil-and-gas operations, cement plants, and steel mills, the startup says.

Kanin was founded in 2020 in Calgary, Alberta, Canada. It opened offices at Greentown Labs Houston in July 2022.
