Ten Houston-area companies will receive vouchers from the Department of Energy's latest round of funding to support the adoption of clean energy tech.

The companies are among 111 organizations to receive up to $250,000 in vouchers from the DOE's Office of Technology Transitions, totaling $9.8 million in funding, according to a release from the department.

The voucher program is in collaboration with the Offices of Clean Energy Demonstrations (OCED), Fossil Energy and Carbon Management (FECM), and Energy Efficiency and Renewable Energy (EERE). It is funded by the Bipartisan Infrastructure Law.

“It takes a breadth of tools and expertise to bring an innovative technology from research and development to deployment,” Vanessa Z. Chan, DOE Chief Commercialization Officer and Director of the Office of Technology Transitions, says in a statement. “The Voucher Program will pair 111 clean energy solutions with the support they need from expert voucher providers to help usher new technologies to market.”

In addition to the funding, the program seeks to help small businesses and non-traditional organizations gain access to testing facilities and third-party expertise.

The vouchers come in five different opportunities that focus on different areas of business growth and support:

  • Voucher Opportunity 1 (VO1) - Pre-Demonstration Commercialization Support
  • Voucher Opportunity 2 (VO2) - Performance Validation, Modeling, and Certification Support
  • Voucher Opportunity 3 (VO3) - Clean Energy Demonstration Project Siting/Permitting Support
  • Voucher Opportunity 4 (VO4) - Commercialization Support (for companies with a functional technology prototype)
  • Voucher Opportunity 5 (VO5) - Commercialization Support (for developers, including for-profit firms, that are working to commercialize a prototype that fits a specific technology vertical of interest for DOE)

The 10 Houston-area companies to receive funding, their voucher type and projects include:

  • Terradote Inc. with Big Blue Technologies Inc. (VO2): Full ISO-Compliant Life Cycle Assessment for Clean Energy Technologies
  • Solugen Inc. and Encina with ACTion Battery Technologies L.L.C. and Frontline Waste Holding LLC (Vo2): Barracuda Virtual Reactor Simulation, Validation and Testing
  • Flow Safe with Concept Group LLC and Precision Fluid Control (VO2): Durability Testing of Hydrogen Components, Materials, and Storage Systems
  • Percheron Power LLC (VO4): Fundraising Support
  • Capwell Services Inc. with Banyu Carbon Inc. (VO5): Field Testing Support for Validation of Novel Resource Sustainability Technologies
  • Syzygy Plasmonics with Ample Carbon PBC, Terraform Industries, Lydian Labs Inc. and Vycarb Inc. (VO5): Rapid Life Cycle Assessment for Carbon Management or Resource Sustainability Technologies
  • Solidec Inc. with GreenFire Energy (VO5): LCA Calculator Tool for Carbon Management or Resource Sustainability Technologies
  • Encino Environmental Services LLC with Wood Cache, Completion Corp and Carbon Lockdown (VO5): Realtime Above/Underground Gas Monitoring Reporting and Verification, Including Cloud Connectivity for Remote Sites
  • Mati Carbon PBC with Ebb Carbon Inc. (VO5): Community Benefits Assessment and Environmental Justice

Other Texas-based companies to receive funding included Molecular Rebar Design LLC and Talus Renewables from Austin, Deep Anchor Solutions from College Station, and ACTion Battery Technologies LLC from Wichita Falls.

Last October, the DOE also awarded the Houston area more than $2 million for projects that improve energy efficiency and infrastructure in the region.

In December, its Office of Clean Energy Demonstrations also selected a Houston power company for a commercial-scale carbon capture and storage project cost-sharing agreement.

Houston energy transition hub opens applications for new fundraising cohort

apply now

EnergyTech Cypher has opened applications for its second Liftoff fundraising program.

Applications close May 20 for the 10-week virtual fundraising sprint. The program is geared toward energy and climatech founders preparing to raise their first institutional round. It will cover fundraising requisites, like pitch materials, term sheet negotiation and round closing, according to a release from EnergyTech Cypher.

The program kicks off June 1 and runs every Monday from 1-3 p.m. CST. It will conclude with an in-person capstone simulation in Houston on August 3, where founders will work to close a mock round.

Jason Ethier, EnergyTech Cypher founder and CEO, will lead the program with Payal Patel, an EnergyTech fellow and entrepreneur in residence.

The program is available through Cephyron, EnergyTech Cypher's new investor relationship management platform, built specifically for energy and climatech founders. Users must have a Cephyron Boost membership to participate in the Liftoff program.

The Cephyron IRM app recently went live and is available to founders at any point in their fundraising process, according to the news release. The platform aggregates investor data, tracks market signals and delivers curated weekly recommendations.

EnergyTech Cypher launched Liftoff last year. The inaugural cohort included 19 startups, including Houston-based AtmoSpark Technologies, The Woodlands-based Resollant and others. Each participant closed at least one fundraising deal, according to EnergyTech Cypher.

EnergyTech Cypher rebranded from EnergyTech Nexus earlier this year. It also launched its CoPilot accelerator in 2025. The inaugural group presented its first showcase during CERAWeek last month.

EnergyTech Cypher's annual Pilotathon Pilot Pitch and Showcase applications also opened this month. Find more information here.
