9 startups join Houston climatech accelerator to tackle carbon capture, energy efficiency, and more

FRESH CROP

Greentown Labs closed out the second quarter with the addition of 17 startups, and just over half are collaborating with the Houston location.

The technology represented by the new additions span the industries of energy, agriculture, and manufacturing, with a focus on carbon capture, electrical usage efficiency, and resource accessibility.

Carbon capture

Two of the newest Houston members, Capture6 and C-Quester, are also part of the Carbon2Value Initiative, a global partnership between the Greentown Labs, Urban Future Lab in New York, and Fraunhofer, headquartered in Michigan. C2V focuses on accelerating technology solutions that capture carbon dioxide for conversion into value-adding products and services.

Similar to the way a sponge is moistened and later wrung out, C-Quester pulls CO2 from flue gas into a temperature-sensitive material that can be heated later to release carbon, making the storage and transport of CO2 easier to manage.

Capture6 uses CO2 pulled from the atmosphere through their Direct Air Capture technology in combination with water treatment methodologies to remove excess salinity from saltwater and brine, resulting in greater freshwater recovery, usable elements for a variety of industries, and carbonates transformed into mineralized form to prevent continued carbon emissions.

Energy efficiency

The Helix MICRA filters created by Helix Earth Technologies can remove CO2 from power plants and other pollutants commonly encountered in the shipping industry. The filtering technology, initially developed for NASA, also dehumidifies air conditioning systems for more efficient energy use.

H2PRO uses its water-splitting technology, E-TAC, to produce green hydrogen in a two-step process that requires less energy to perform than the more common process of electrolysis with improved safety aspects.

Steam production and distribution get an upgrade with Imperium Technologies, the first electromechanical solution that enables previously unseen systems monitoring for reduction in greenhouse gas emissions by 20%, on average.

With a keen focus on predictive insights, eologix deploys smart sensors to give operators advance warning of situations that could cause rotor imbalances to keep wind turbines – and the energy they produce – optimized.

Resource accessibility

NW NA supports the goals of stability, predictability, and accessibility of electric-powered vehicle use with its high-power EV-charging station, mobile electricity storage units, and renewable energy measurement and forecasting tool.

From the Metaversity under development, to its oil and gas line leak detection systems, Kauel goes all-in on AI for its clients, even helping children with kinesthetic rehabilitation through augmented and virtual reality programs.

Finally, SkyH2O brings fresh, clean water to areas with limited access to existing infrastructure or natural water resources for commercial, military, and industrial use.

Another eight startups join the cohort named above as members of the Greentown Labs Boston location: Capro-X, Carbon2Stone, Cottage, Dioxycle, enaDyne, Global Algae Innovations, Terrafixing, and Thola.

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.
