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.

Money moves

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 healthtech startup raises $30M to scale surgical healing gel

fresh funding

Houston-based healthtech startup TYBR Health has raised a $30 million Series A round to scale its B3 GEL System, which helps protect tendons from scarring after surgery.

The round was led by Minneapolis-based Vensana Capital and Cleveland-based Mutual Capital Partners, with participation from Denver-based Neovate Capital Partners and existing investors, according to a news release from the company.

TYBR Health said it plans to use the funding to broaden the B3 GEL System's clinical applications, expand commercialization and conduct studies to evaluate its ability to protect tissue and improve healing outcomes.

"Surgeons are exceptionally good at the structural repair, but the biology that follows is what determines how it heals. That part of the equation has gone largely unaddressed ... There's a shift underway across surgical specialties, from focusing almost entirely on the mechanical repair to also weighing the biological conditions that repair needs to succeed," Tim Keane, co-founder and CEO of TYBR Health, said in the news release. "This financing lets us reach more surgeons and generate the clinical evidence to move that shift forward."

As part of the financing round, Greg Banker of Vensana Capital and Liz Todia Zambory of Mutual Capital Partners will join the TYBR board, alongside independent director Aaron Smith.

"TYBR Health is addressing a gap surgeons have lived with for a long time, with a product that fits the way they already work," Zambory, principal at Mutual Capital Partners, added in the release. "We're excited to co-lead this round and support the company's growth."

TYBR was founded in 2020 and originated from the TMCi’s Biodesign fellowship and participated in the TMC's Accelerator for HealthTech. Its B3 GEL System is a flowable extracellular matrix hydrogel designed to protect tendons, ligaments, muscles, and the surrounding soft tissue while they heal from orthopedic surgery. It received FDA 510(k) clearance last June and launched an Australian clinical trial in the fall.

The B3 GEL System has been used in hand, wrist, shoulder, foot and ankle, and sports medicine procedures since it launched, according to the company, and was first used in the clinical setting earlier this year by Dr. Tammam Hanna with Texas Tech University Health Sciences Center.

Houston space companies win NASA funding to build Mars exploration robots

mission to mars

Two Houston-area spacetech companies have landed a portion of a $17 million award from NASA to develop robots for exploring the surface of Mars, the agency announced this month.

Houston-based Inuitive Machines and Webster, Texas-based MEI Technologies, which does business as Aegis Aerospace, were among the seven companies selected to receive the funding from NASA's Science Transport and Robotic Innovation for Deployment and Exploration (STRIDE) initiative.

According to the release from NASA, the companies are tasked with creating "innovative mobility systems" that would allow future Mars missions to access more challenging terrain and difficult-to-reach regions of the planet, and to travel farther distances. NASA estimated that the work will begin this fall.

NASA solicited proposals for participants in the STRIDE initiative in January. The seven named companies are the first selected to participate in the program.

The additional five companies to receive STRIDE funding include:

"STRIDE demonstrates NASA’s commitment to strong public-private partnerships, allowing the agency to explore new approaches for Mars surface exploration while identifying key capability gaps and development needs for commercial systems that could operate and traverse realistic Martian environments," NASA shared in the announcement.

Last month, Intuitive Machines was awarded $148.3 million to deliver its Nova-C lander to the moon. The funding was part of $600 million the space agency awarded to three companies as part of its Moon Base Program and was Intuitive Machines' sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program. Astrobotic was also one of the companies to land funding for the Moon Base program, as well as Austin-based Firefly Aerospace.

Around the same time, Firefly Aerospace was awarded a $13 million subcontract from NASA’s Jet Propulsion Laboratory to develop technology for NASA’s SkyFall mission to Mars. The mission aims to deploy three Mars helicopters to "perform science and demonstrate airborne subsurface mapping and resource prospecting on the planet." Read more here.
