Greentown Labs announced that it added five startups to its Houston community in Q1 of 2025.

The companies are among a group of 19 that joined the climatetech incubator, which is co-located in Houston and Boston, in the same time period. The companies that joined the Houston-based lab specialize in a number of "green" applications, from converting plastic waste into sustainable materials to developing energy-storage solutions.

The new Houston members include:

  • Concept Loop, a project of Pakistan-based Innova8e Inc., aims to repurpose post-industrial and post-consumer plastic waste into sustainable building materials.
  • GeoFuels, a Sugar Land-based company that produces hydrogen by using baseload geothermal power and methane pyrolysis.
  • PLASENE, a Houston-based company with an innovative platform that converts plastic waste into liquid fuel and low-carbon hydrogen through its proprietary catalysts and modular, scalable, pre-engineered units platform. The company was named to Greentown's ACCEL Year 3 cohort earlier this year.
  • RepAir Carbon, an Israeli company with a fully electric, zero-heat carbon-removal technology that consumes minimal energy, operates without liquids or solvents, and produces no hazardous materials or waste.
  • RotorVault from Pasadena, California, is commercializing energy-storage and load-following solutions that are containerized, modular, and field-deployable systems built on flywheel technology.

Fourteen other companies will join Greentown Boston's incubator. See the full list here.

PLASENE and five other new members—Thola, Respire Energy, Andros Innovations, FAST Metals and Tato Labs—join Greentown Labs through its most recent Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, cohort. ACCEL, which works to advance BIPOC-led startups in the climatetech space, announced its third cohort last month.

Houston-based The Welch Foundation has issued $700,000 in additional funding to support chemical research through two of its newest grant programs.

The foundation has named the recipients of its Welch eXperimental (WelchX) Collaboration Retreat and Pilot Grants and the Welch Postdoctoral Fellows of the Life Sciences Research Foundation Grants.

The WelchX grants were awarded to teams of two Texas researchers who presented "innovative and collaborative ideas" addressing challenges in the clean energy space, according to the foundation.

Researchers from Texas universities gathered in Houston earlier this summer to discuss the theme “Chemical Research for Grand Challenges." They then paired off into nine teams and submitted proposals for the $100,000 pilot grants. The seven selected teams, several with ties to Houston, and their research topics include:

  • Yimo Han, Rice University, and Yuanyue Liu, The University of Texas at Austin, “Stabilizing Copper Electrocatalysts for CO2 Conversion”
  • Ognjen Miljanic, University of Houston, and Indrajit Srivastava, Texas Tech University, “Ping-Pong' Afterglow Luminescence in Self-Assembled Molecular Cubes”
  • Raúl Hernández Sánchez, Rice University, and Andy Thomas, Texas A&M University, “Accelerating Magnetic Resonance Imaging Contrast Agent Discovery via Rapid Injection NMR: Improving the Detection of Lithium for Disease Diagnostics”
  • Benjamin Janesko, Texas Christian University, and MD Masud Rana, Lamar University, “Cyber Twin Chemical Ensembles for Near-Infrared-Emitting Graphene Quantum Dot Therapeutics”
  • Ivan Korendovych, Baylor University, and Dino Villagrán, The University of Texas at El Paso, “Selective Bio-Inspired Electrochemical Probes for PFAS Analysis and Degradation”
  • Samantha Kristufek, Texas Tech University, and Kayla Green, Texas Christian University, “CIRCUIT: Critical Ion Recovery using Conductive and Ultrafiltration Intelligent Technology”
  • Fang Xu, The University of Texas at San Antonio, and Hong Wang, University of North Texas, “Visualize Molecular Adsorption on Supported Ni-porphyrin Model Catalysts via Substitute Effect”

The Welch Postdoctoral Fellows of the Life Sciences Research Foundation provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas.

The foundation previously announced that it would name fellows from Rice University and Baylor University who would receive $100,000 annually for three years. This year's recipients and their research topics include:

  • Teng Yuan, Rice University, “Unlocking New Chemistry of Nonheme Iron Enzymes for α-Amino Acids and γ-Lactones Synthesis”
  • Katelyn Baumler, Baylor University, "Crystal Growth of Ln2Fe4Sb5 Phases Toward the Study of Novel Quantum Properties”

“As these programs become more established, it is thrilling to see the new research our awardees are exploring,” Adam Kuspa, president of The Welch Foundation, said in a news release. “The Foundation is very pleased by the applications that we continue to receive describing exciting new research projects to advance chemical research.”

This additional funding comes on the heels of the foundation doling out $27 million for chemical research, equipment and postdoctoral fellowships earlier this summer. The foundation made 85 grants to faculty at 16 Texas institutions at the time. Read more here.
