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.

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.
