A Houston-based company that's got a solution to renewable energy storage 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 in November. 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 battery innovators receive $4M in federal funding

money moves

Houston-based Zeta Energy announced this week that it was selected to receive $4 million in federal funding for the development of efficient electric vehicle batteries.

The funds come from the U.S. Department of Energy's ARPA-E Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program, which aims to increase the number of EVs on the roads by boosting the country’s supply chain of affordable, convenient, reliable and safe batteries.

Zeta Energy is one of 12 groups in the U.S. to receive funding from the program, which awarded $42 million in total.

“Electric vehicle sales in America have tripled since the start of this Administration and by addressing battery efficiency, resiliency and affordability, the projects announced today will make EVs attractive to even more drivers,” U.S. Secretary of Energy Jennifer M. Granholm said in a statement released in January. “This is a win-win for our efforts to fight climate change and power America’s clean transportation future with technologies produced by researchers and scientists right here at home.”

Other teams to receive funding include 24M Technologies, national laboratories and universities like The Ohio State University, University of Maryland, Virginia Tech, among others. Zeta is the only Texas-based company to receive funds. It received one of the largest grants among the group.

"We are thrilled to have been selected for funding by the ARPA-E EVs4ALL program," Zeta Energy CEO Tom Pilette said in a statement. "We have been working hard to make this technology a reality, and we are really grateful to receive this recognition of the promise of our technology and the progress we have made on it."

Zeta Energy is known for its lithium sulfur batteries that traditionally have not been long lasting. While sulfur is an economical and abundant material, it traditionally would dissolve after a few uses in lithium sulfur batteries.

However, Zeta uses its proprietary sulfur-based cathodes and lithium metal anodes that have shown to have higher capacity and density and better safety profiles, according to the company's website.

According to ARPAE, the company will create a new anode that will "be highly accessible and rechargeable" with the funding.

Zeta Energy closed a $23 million series A round led by New York VC firm Moore Strategic Ventures about a year ago. In addition to applications for electric vehicles, the company's technology is also expected to have uses in grid energy storage.

Utah solar company acquires Houston projects, expands to Texas

solar deals

Utah-based solar technology and battery storage company SunPower has announced its expansion into Texas by acquiring “prime project assets” from Houston installer Green Light Solar.

As part of the deal, Green Light Solar CEO James Garrett will lead SunPower’s U.S. installation group. Garrett is based in the Houston area, according to LinkedIn.

Green Light Solar focuses on residential and commercial solar installations, battery backups and whole-home generators throughout Texas, Louisiana, Oklahoma and Colorado. As of press time, SunPower had not disclosed which specific projects or assets were included in the acquisition.

In addition to the Green Light acquisition, SunPower also announced its second strategic partnership with Fort Worth-based SOLRITE Energy, which provides solar and battery project financing and virtual power plant capabilities.

Through the partnership, SunPower plans to expand its residential solar and battery storage business and grow its virtual power plant (VPP) network in Texas.

A virtual power plant is a network of connected energy sources that can supply electricity to the grid when demand is high. The network draws on energy stored in individual residential and commercial battery systems. VPPs can also help participating homeowners generate additional revenue by selling their stored power.

“SOLRITE not only sources projects to us but also provides project funding for innovative systems with large batteries connected to a VPP, enabling power sales into the open market,” T. J. Rodgers, SunPower CEO, said in a news release. “That VPP capability provides an extra source of income that SOLRITE shares with homeowners and EPCs, making SOLRITE an attractive partner.”

SunPower will bring its sales, installation and lifetime warranty support to the partnership, while SOLRITE will provide its virtual power plant platform and solar financing capabilities, according to the release.

"Building our VPP business is a key part of SunPower’s growth strategy going forward,” Kapil Rai, EVP of Direct at SunPower, added in the release. “Our partnership with SOLRITE gives us a path to bring together customer acquisition, solar, storage deployment, and financing to develop this business in Texas and beyond.”
