Chevron launches $500M clean energy fund to target low carbon fuels, advanced materials

fresh funding

Chevron Technology Ventures has announced its latest fund raised to deploy capital into clean energy technology.

CTV's Future Energy Fund III has reportedly launched with $500 million — an increase from its second fund from 2021 that was valued at $400 million. The inaugural Future Energy Fund was established in 2018. Each fund has targeted separate technologies — from capture, emerging mobility, and energy storage in fund I to industrial decarbonization, emerging mobility, energy decentralization, and circular economy in fund II.

"Future Energy Fund III, launched in 2024, will continue to look forward in the areas of focus for the earlier two funds and aims to expand investment in the areas of novel low carbon fuels, advanced materials, and transforming carbon to higher-value products," reads Chevron's website describing the Future Energy Funds.

The first two funds have invested in over 30 companies and has more than 250 other investors supporting low-carbon innovations.

CTV, based in Houston, has strategic partnerships with organizations within the Houston innovation ecosystem, including Greentown Labs, Rice Alliance for Technology and Entrepreneurship, the Ion, The Cannon, and the HX Venture Fund.

"CTV engages a range of startup companies, investors, incubators and accelerators to access technology that can be used across Chevron now and in the future to enable us to operate more efficiently, to lower the carbon intensity of our operations and launch viable new businesses," reads the CTV site.

Founded in 1999, CTV invests in emerging energy technologies as well as incubating startups in its Catalyst Program. Last month, CTV added Cerebre, a software-as-a-service company that works with its customers to unlock and leverage data to tap into AI tools and digitization, to the Catalyst Program.

Japanese company launches solar module manufacturing at Houston-area plant

solar plant

A local subsidiary of a Japanese solar equipment manufacturer recently began producing solar modules at a new plant in Humble.

TOYO Co. Ltd.’s TOYO Solar LLC subsidiary can produce 1 gigawatt worth of solar modules per year at a 567,140-square-foot plant it leases in Lovett Industrial’s Nexus North Logistics Park on Greens Road. TOYO Solar’s next phase will accommodate 2.5 gigawatts’ worth of solar module manufacturing. The subsidiary eventually plans to expand manufacturing capacity to 6.5 gigawatts.

For now, TOYO Solar operates only one assembly line at the Humble plant. Once TOYO Solar has five assembly lines up and running, it could employ as many as 750 manufacturing workers there, according to Connect CRE.

TOYO says the plant enlarges its U.S. footprint “to be closer to the majority of its clients, meet the demand for American-made solar panels, and contribute to the growing demand for secure, sustainable energy solutions as demands on the grid continue to rise.”

Last month, TOYO purchased the remaining 24.99 percent stake in TOYO Solar to make it a wholly owned subsidiary. TOYO entered the Houston-area market through its 2024 acquisition of a majority stake in Solar Plus Technology Texas LLC.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

NRG makes latest partnership to grow virtual power plant

VPP partners

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
