Greentown Labs announced that it added nine climatetech start-ups in Q2 of this year.

The new members of the incubator, which is co-located in Houston and Boston, work in a variety of fields from electricity to manufacturing and agriculture.

The companies in the Houston location include:

  • GS Vortex Systems, a Portland-based company that focuses on cost reduction and flow assurance in piping systems. Its hydrodynamic flow technology allows for higher flow through existing pipes that increases productivity and reduces emissions. It’s based in Houston and Tampa.
  • BiaTech Corporation, applies AI and machine learning fto natural resource infrastructure immersion to help energy and utilities produce more with lower risks of production disruptions
  • InfraNergy, a Florida-based clean energy infrastructure provider that develops clean energy projects via virtual power plants to reduce power costs and drive decarbonization
  • Neuralix, a Dallas-based startup that offers a suite of rapid, customizable templates for data lifecycle for the energy and manufacturing sectors
  • Reverse Energy Solutions, a Chicago-based startup that provides cost-effective solar panel recycling through streamlined collection and transportation processes
  • Terralytiq, which has developed an enterprise software platform for industrial supply chains, that helps reduce supply chain costs and carbon. It’s headquartered in Austin.
  • EnergyGigs, a talent and freelance platform for the energy industry based in Houston
  • Metalex, a commodity trading firm with operations in Africa that delivers carbon-neutral critical metals that are processed in a decarbonized supply chain
  • TDS Select, which has developed a modular, scalable water-treatment technology to desalinate brackish water using low-energy

According to Greentown, another 11 startups joined the nonprofit's Boston incubator.

Greentown Labs, with the Browning the Green Space, named the second cohort for the Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, in the spring. The accelerator, which works to advance BIPOC-led startups in the climatetech space, launched in 2022.

It also named 6 energy tech startups to Shell-backed accelerator in October.

Earlier this month the climatetech incubator added three new members to its board of directors. This came after CEO and President Kevin Knobloch announced he would be stepping down at the end of July. Kevin Dutt was recently named interim CEO of the organization.

New UH white paper details Texas grid's shortfalls

grid warning

Two University of Houston researchers are issuing a warning about the Texas power grid: Its current infrastructure falls short of what’s needed to keep pace with rising demand for electricity.

The warning comes in a new whitepaper authored by Ramanan Krishnamoorti, vice president of energy and innovation at UH, and researcher Aparajita Datta, a Ph.D candidate at UH.

“As data centers pop up around the Lone Star State, electric vehicles become more commonplace, industries adopt decarbonization technologies, demographics change, and temperatures rise statewide, electricity needs in Texas could double by 2035,” a UH news release says. “If electrification continues to grow unconstrained, demand could even quadruple over the next decade.”

Without significant upgrades to power plants and supporting infrastructure, Texas could see electricity shortages, rising power costs and more stress on the state’s grid in coming years, the researchers say. The Electric Reliability Council of Texas (ERCOT) grid serves 90 percent of the state.

“Texas, like much of the nation, has fallen behind on infrastructure updates, and the state’s growing population, diversified economy and frequent severe weather events are increasing the strain on the grid,” Datta says. “Texas must improve its grid to ensure people in the state have access to reliable, affordable, and resilient energy systems so we can preserve and grow the quality of life in the state.”

The whitepaper’s authors caution that Texas faces a potential electricity shortfall of up to 40 gigawatts annually by 2035 if the grid doesn’t expand, with a more probable shortfall of about 27 gigawatts. And they allude to a repeat of the massive power outages in Texas during Winter Storm Uri in February 2021.

One gigawatt of electricity can power an estimated 750,000 homes in Texas, according to the Texas Solar + Storage Association.

The state’s current energy mix includes 40 percent natural gas, 29 percent wind, 12 percent coal, 10 percent nuclear and eight percent solar, the authors say.

Despite surging demand, 360 gigawatts of solar and battery storage projects are stuck in ERCOT’s queue, according to the researchers, and new natural gas plants have been delayed or withdrawn due to supply chain challenges, bureaucratic delays, policy uncertainties and shifting financial incentives.

Senate Bill 6, recently signed by Gov. Greg Abbott, calls for demand-response mandates, clearer rate structures and new load management requirements for big users of power like data centers and AI hubs.

“While these provisions are a step in the right direction,” says Datta, “Texas needs more responsive and prompt policy action to secure grid reliability, address the geographic mismatch between electricity demand and supply centers, and maintain the state’s global leadership in energy.”

Houston-area logistics co. breaks ground on recycling center tied to circularity hub

coming soon

TALKE USA Inc., a Houston-area arm of German logistics company TALKE, broke ground on its new Recycling Support Center in Mont Belvieu Aug. 1.

The facility will process post-consumer plastic materials, which will then be further processed at Cyclyx's new Houston-based Circularity Center, a first-of-its-kind plastic waste sorting and processing facility that was developed through a joint venture between Cyclix, ExxonMobil and LyondellBasell.

The materials will ultimately be converted into recycling feedstock.

“We’re proud to break ground on a facility that reflects our long-term vision for sustainable growth,” Richard Heath, CEO and president of TALKE USA Inc., said in a news release. “This groundbreaking marks an important milestone for our team, our customers, and the Mont Belvieu community.”

The new facility was partially funded by Chambers County, according to the release. The Baytown Sun reports that the county put $1 million towards the construction of the project, which brings advanced recycling and mechanical recycling to the area.

TALKE USA said it plans to share more about the new facility and its impact in the future.

Meanwhile, the Houston-based Cyclyx Circularity Center (CCC1) is slated to open this year and is expected to produce 300 million pounds of custom-formulated feedstock annually. A second circularity center, CCC2, is expected to start up in the Dallas-Fort Worth area in the second half of 2026. Read more here.

8 Houston energy giants top global corporate startup index for 2025

Global Group

Eight major players in Houston’s energy industry rank among the world’s top 20 energy companies for corporate startup activity.

The inaugural Corporate Startup Activity Index 2025, published by StartupBlink, ranks global corporations by industry. The eight Houston-area employers fall into the index’s energy and environment category.

Researchers from StartupBlink, an innovation research platform, scored more than 370 companies based on three factors: corporate involvement in startup activity, startup success and ecosystem integration.

The eight Houston-area energy employers that landed in the energy and environment category’s top 20 are:

  • No. 3 BP. Score: 13.547. U.S. headquarters in Houston.
  • No. 5 Saudi Aramco. Score: 7.405. Americas headquarters in Houston.
  • No. 7 Eni. Score: 6.255. Headquarters of Eni U.S. Operating Co. in Houston.
  • No. 8 Shell. Score: 6.217. U.S. headquarters in Houston.
  • No. 11 Occidental Petroleum. Score: 5.347. Global headquarters in Houston.
  • No. 15 Engie. Score: 3.352. North American headquarters in Houston.
  • No. 17 Repsol. Score: 2.980. U.S. headquarters for oil and gas operations in The Woodlands.
  • No. 19 Chevron. Score: 2.017. Global headquarters in Houston.

“Building a startup is hard, and navigating corporate innovation can be just as complex. This ranking is a step toward making the connection between startups and corporations more transparent, enabling startups and corporations to collaborate more effectively for mutual success,” said Eli David Rokah, CEO of StartupBlink.

Salesforce topped the global index with a score of 380.090, followed by Intel, Google, Qualcomm, and Comcast.
