A Houston-based company that's got a solution to renewable energy storage has just secured funding from a federal entity.

The U.S. Department of Energy Advanced Research Projects Agency-Energy, or ARPA-E, is granting Quidnet Energy $10 million in funding, the Houston company announced this week. The funding is a part of the ARPA-E Seeding Critical Advances for Leading Energy technologies with Untapped Potential, the SCALEUP program. This initiative is aimed at providing funding to previous ARPA-E teams "that have been determined to be feasible for widespread deployment and commercialization domestically," per a news release.

“We’re honored that ARPA-E has selected Quidnet Energy as an awardee of the SCALEUP program,” says Joe Zhou, CEO of Quidnet Energy, in the release. “This funding will support continued work on our Geomechanical Pumped Storage (GPS) project with CPS Energy, which will demonstrate the benefits of using proven pumped hydro technology to create a long-duration energy storage resource that doesn’t require mountainous terrain. We look forward to continuing our partnership with CPS Energy and thank ARPA-E for acknowledging the potential of GPS for long-duration storage.”

The company's technology can store renewable energy for long periods of time in large quantities. The process includes storing pressurized water underground and, when the stored energy is needed, the water propels hydroelectric turbines and produces the electricity to support the grid at a fraction of the cost, per the news release. The concept is similar to existing gravity-powered pumped storage, but with less land required.

The fresh funding will be used toward Quidnet Energy’s ongoing project with San Antonio-based utilitary provider CPS Energy. This collaboration is scaling the company's GPS to a 1 MW/10 MWh commercial system, per the release, that will provide CPS Energy with over 10 hour long-duration energy storage system.

In 2020, Quidnet closed its $10 million series B financing round and secured a major contract with the New York State Energy Development Authority. The series B round included participation from Bill Gates-backed Breakthrough Energy Ventures and Canada-based Evok Innovations, which both previously invested in the company, as well as new investors Trafigura and The Jeremy and Hannelore Grantham Environmental Trust.

Houston-based renewable energy company that focuses on clean energy storage closed its $10 million series B financing round and secured a major contract.

Quidnet Energy announced its latest round and the execution of a contract with the New York State Energy Development Authority. Bill Gates-backed Breakthrough Energy Ventures and Canada-based Evok Innovations, which both previously invested in the company, contributed to the round. The round also featured new investors Trafigura and The Jeremy and Hannelore Grantham Environmental Trust.

"Long-duration electricity storage is critical to the energy transition. It's exciting to see how Quidnet is bringing this viable long-duration solution to the market," says Mike Biddle, managing director at Evok Innovations, in a news release. "Because they are leveraging long understood geologic principles, we are confident that they can scale rapidly. We are pleased to support the Quidnet team through its next phase of commercial growth."

According to the release, the company will use the funds to grow its team and scale up its operations in order to be able to deliver commercial-scale projects across the country's electric grid.

"Integrating renewables and replacing retiring thermal generation require cost-effective long-duration electricity storage at an immense scale," says Quidnet Energy CEO Joe Zhou in the release. "While traditional pumped hydro has provided over 95 percent of the world's grid-scale storage, that approach faces significant siting and cost limitations going forward. Quidnet unlocks these constraints to fundamentally change the economics and deployment profile of long-duration storage."

Quidnet's deal with NYSEDA is a part of the organization's efforts to reduce the state's carbon footprint while also lowering the cost of traditional energy storage.

"Under Governor Cuomo's leadership, New York is investing in the technology research and development needed to advance a 21st electric grid that can support the State's growing influx of renewable energy," says Alicia Barton, president and CEO of NYSERDA, in the release. "Congratulations to Quidnet on this opportunity to develop and demonstrate the value that this innovative technology can bring to New York as we work to reduce greenhouse gas emissions and transition to a 100 percent clean electric grid."

Last month, the Rice Alliance for Technology and Entrepreneurship hosted its annual Energy Tech Venture Day online, and Quidnet was among the Houston energy companies to pitch virtually.

13 Houston energy tech startups pitch at Rice Alliance's first virtual event

online only

Rice Alliance for Technology and Entrepreneurship's annual Energy Tech Venture Day is usually hosted as a part of the Offshore Technology Conference that takes over NRG Center each May. However, when OTC announced its cancelation, Rice Alliance made sure the show would go on.

"We had many startups and corporations reach out to us and ask us if we could go ahead with the event in a virtual format, so that's how we ended up where we are today," says Brad Burke, managing director of the Rice Alliance at the start of the event.

Throughout the two-hour pitch event, 39 startups pitched their companies in two minutes and 30 seconds or less. The companies were selected based on input from the alliance's energy advisory board. The companies, Burke says, represent innovations across the energy industry.

An additional 24 companies participated in virtual office hours with investors through a speed-networking process.

"We know that the needs of startups to raise capital, to find customers, and to find pilots is even greater today than it was several months ago," Burke says. "And we know that the needs of energy companies to find innovative technologies to reduce costs and increase production are even greater as well."

Usually at this event, the advisory board decides on the 10 most promising energy tech startups, however, this list will not be revealed this year.

Of the startups that pitched that represented 11 different states and six different countries, 13 call Houston their HQ. Here's what local startups pitched.

Houston Innovation Awards honor Don Kendall Jr. with posthumous​ Trailblazer Legacy Award

lasting legacy

Every year, the Houston Innovation Awards honor one Houstonian with the Trailblazer Award, whose impact is felt throughout the city's innovation and business ecosystem.

This year, the Trailblazer Legacy Award will be given posthumously to Don Kendall Jr., who died in September while on a trip to the Republic of the Congo with the Jane Goodall Institute, one of the many organizations he was deeply involved with.

Kendall's obituary puts it simply: "Don’s truest passions were conservation and his family." Many saw those passions play out in his career, particularly in the role he played in shaping Houston's clean energy sector.

Kendall served as general partner of New Climate Ventures, a Houston-based early-stage venture capital firm that invests in next-gen energy, materials and fuel technologies and startups. The firm's portfolio includes Houston-based clean energy companies like Solidec, Syzygy Plasmonics and Rheom Materials.

Kendall was also founding managing director and CEO of Kenmont Capital LP. He ran a $500 million distressed debt and credit-based hedge fund focused on the energy, power and transportation sectors and one of the top-performing private equity funds under the Kenmont umbrella.

He served on the board of Talos Energy, American Midstream Partners, Syzygy Plasmonics, Tangent Energy, Stream Energy and others. Notably, he served as Chair of the Special Committee of the SolarCity board during its acquisition by Tesla in 2016. According to his obituary, Kendall negotiated with "Elon Musk in the middle of the night on a rickety pier in Indonesia after eluding a poisonous snake."

Outside of the clean energy space, Kendall also served on the boards of the Jane Goodall Institute, Earthwatch International and Ecological Defense Group. He also served as vice chair of the Houston Zoo Inc. and chair of its Conservation Committee.

Kendall was selected by our esteemed panel of judges to receive the 2026 Trailblazer Legacy Award. The panel includes carbon removal entrepreneur and CEO of Houston-based Mars Materials Aaron Fitzgerald.

Fitzgerald shares the profound impact Kendall had on his career and those of many others.

"Honoring Don with the Trailblazer Legacy Award is a fitting tribute to a leader whose impact spanned civic work with the Houston Zoo, wildlife conservation, and the growth of our startup ecosystem," Fitzgerald says. "He paired a keen eye for potential with the relentless drive to unlock it. For Mars Materials, his early backing carried us through a critical valley when we needed belief the most, and his presence as a personal mentor is profoundly missed."

Don was an avid traveler, cyclist and collector. He is survived by his wife of 50 years, Diane S. Kendall. A celebration of life will be held early in 2027.

2 Houston suburbs rank among 5 best cities to retire, says U.S. News

Slowing Down

Houston and nine of its suburbs are earning new acclaim on U.S. News and World Report's just-released list of the best U.S. cities for retirees in 2027. Two northern suburbs, The Woodlands and Spring, are resting easy among the top five nationwide.

The 2027 Best Places to Retire list evaluated over 850 U.S. cities based on six livability metrics that best serve American retirees: quality of life, affordability, health care, retiree taxes, job market, and population and migration. The top 250 finalist cities were then ranked nationally and by city size.

Midland, Michigan topped the list for the second consecutive year and is followed by Homosassa Springs, Florida (No. 2) and Weirton, West Virginia (No. 3).

The Woodlands and Spring respectively maintained their standings as the No. 4 and No. 5 best cities for retirees for the second year in a row. The Woodlands topped the separate list of the best midsized U.S. cities to retire, while Spring landed 5th among the smallest U.S. cities.

Houston proper was declared the No. 2 best big city for retirees, and it ranked 89th overall. Elsewhere in the metro, Pearland (No. 13) and Conroe (No. 14) ranked just outside the overall top 10 but ranked 4th and 5th among the best midsized cities for retirees.

U.S. News said affordability is the "most considered factor" when it comes to picking the best place to live a low-stress retirement life, and that's what Houston and its neighbors deliver. Affordable cities also give retirees "a sense of security and comfort as they live out their golden years," according to Megan Wood, U.S. News assistant managing editor of home services and real estate.

"It’s no secret that affordability is top of mind for Americans this year, which is why U.S. News updated its weighting criteria to better align with what retirees prioritize," Wood said. "The 2027 rankings reflect key metrics used to highlight the places that
best suit retiree needs."

Sugar Land was declared the 10th best place to live in the U.S. in a separate U.S. News report earlier this year, but it doesn't quite meet the expectations for retirees. This particular suburb ranked as the 45th best overall city to retire, but it fared better in the city size ranking and landed 13th among the biggest U.S. cities.

Pasadena also surprised as the 85th best place to retire nationwide in this report, despite being hailed as the No. 3 best city to retire in Texas by RetirementLiving.com.

Three more Houston neighbors ranked among the top 100 overall best places to retire for 2027: League City (No. 25), Missouri City (No. 49), and Baytown (No. 88).

These are the top 10 best U.S. cities to retire for 2027:

  • No. 1 – Midland, Michigan
  • No. 2 – Homosassa Springs, Florida
  • No. 3 – Weirton, West Virginia
  • No. 4 – The Woodlands
  • No. 5 – Spring, Texas
  • No. 6 – Rio Rancho, New Mexico
  • No. 7 – Altoona, Pennsylvania
  • No. 8 – Paducah, Kentucky
  • No. 9 – Lynchburg, Virginia
  • No. 10 – Palm Coast, Florida
