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.

Expert on powering Texas: The promise and challenges of renewable energy

Guest Column

Texas leads the nation in wind and solar energy, but that leadership is being tested as a surge in project cancellations raises new concerns about the future of renewables in the state.

While Texas clean energy has grown significantly in recent years, solar and wind often fall short of meeting peak electricity demand. As extreme weather, rising demand, and project cancellations strain the grid, Texas must confront the growing gap between renewable potential and real-time reliability.

Solar and Wind Energy

Solar generation in the Lone Star State has grown substantially over the past decade. The Texas solar industry is estimated to employ over 12,000 Texans and is contributing billions in local tax revenue and landowner income, and solar and storage are the largest sources of new energy on the Texas grid.

With a significant number of sunny days, Texas’ geography also enables it to be among the states with the greatest energy potential for solar power generation. Further moving to advance the use of solar energy generation, the 89th Texas legislature passed SB 1202 which accelerates the permitting process for home solar and energy storage installations. SB 1202 empowers homeowners to strengthen their own energy security and supports greater grid resilience across the state.

Texas has also led the United States in wind energy production for more than 17 years, with 239 wind-related projects and over 15,300 wind turbines, which is more than any other state. The economic impact of wind energy in Texas is substantial, with the industry contributing $1.7 billion a year to the state’s gross domestic product. With wind electric power generation jobs offering an average annual wage of $109,826, the growing sector provides lucrative employment opportunities.

However, solar and wind currently struggle to meet Texas’ peak electricity demand from 5 pm to 7 pm — a time when millions of residents return home, temperatures remain high and air conditioner use surges. Solar generation begins to decline just as demand ramps up, and wind production is often inconsistent during these hours. Without sufficient long-duration storage or dispatchable backup power, this mismatch between supply and demand presents a significant reliability risk — one that becomes especially urgent during heat waves and extreme weather events, as seen during ERCOT conservation alerts.

Geothermal Energy

Geothermal energy uses heat from beneath the Earth’s surface to provide reliable, low-emission power with minimal land use and no fuel transport. Though it currently supplies a small share of energy, Texas is emerging as a leader in its development, supported by state leaders, industry, and environmentalists. During the 89th legislative session, Texas passed HB 3240 to create a Geothermal Energy Production Policy Council, set to begin work on September 1, 2025.

In 2024, Sage Geosystems was selected to develop geothermal projects at the Naval Air Station in Corpus Christi, expanding its work with the Department of Defense. In partnership with the Environmental Security Technology Certification Program, Sage is using its proprietary Geopressured Geothermal Systems technology to evaluate the potential for geothermal to be a source of clean and consistent energy at the base.

One limitation of geothermal energy is location. Deep drilling is costly, and areas with high water tables, like some coastal regions, may not be viable.

Hydroelectric Energy

While hydropower plays a minor role in Texas’ energy mix, it is still an essential energy source. Its output depends on water availability, which can be affected by seasonal and long-term changes like droughts.

Texas has 26 hydropower plants with a total capacity of nearly 738 megawatts, serving about 2.9 million people as of 2019. Harris County holds 43% of all hydropower generation jobs in the state, and in 2021, hydroelectric power generation contributed $700 million to Texas’ gross domestic product.

Federal funding is helping expand hydropower in Texas. The Southwestern Power Administration has committed about $103 million to support infrastructure, including $32 million for upgrades to Central Texas’s Whitney Dam. The 2021 Inflation Reduction Act added $369 billion in tax credits for clean energy, supporting dam retrofits nationwide. In 2022, the Department of Energy launched over $28 million in new funding through the Infrastructure Law to help meet national clean energy goals by 2035 and carbon neutrality by 2050.

Tidal Energy

Driven by the moon and sun, tidal energy is predictable but limited to coastal areas with strong tides. Although Texas has modest tidal potential, research is ongoing to optimize it. Texas A&M University is developing a floating test platform for hybrid renewable systems, integrating tidal, wave, wind, and solar energy. In addition, St. Mary’s University in San Antonio is prototyping small-scale tidal turbines using 3D printing technology.

While commercial tidal power remains in the research phase, the state’s offshore capabilities, engineering talent, and growing university-led innovation could make it a player in hybrid marine renewable systems. Floating platforms that integrate wave, tide, solar, and wind offer a compelling vision for offshore power generation suited to Texas’ unique coastal conditions.

Biomass Energy

Biomass energy is the largest renewable source worldwide, providing 55% of renewables and over 6% of global energy. While reliable, it can be less efficient, sometimes using more energy to burn the organic matter than it produces, and demand may exceed supply.

In Texas, biomass is a nominal part of the state’s energy portfolio. However, substantial research is being conducted by Texas A&M University to attempt to convert algae and food waste into a cost-efficient source of biomass material. In addition, UK-based biomass and renewable energy company Drax opened its North American headquarters in Houston, which created more than 100 new jobs in Texas’ renewable energy industry.

It’s clear that renewable energy is playing an increasingly important role in shaping Texas’ energy future. But the road ahead demands a realistic view: while these sources can reduce emissions and diversify our generation mix, they do not yet solve for peak load reliability — especially during the critical 5 pm to 7 pm window when grid stress is highest.

Meeting that challenge will require not just investment in renewables, but also innovation in grid-scale storage, flexible generation, market reform and consumer programs. A diversified, resilient energy portfolio — one that includes renewables and reliable dispatchable sources — will be the key to ensuring that Texas remains powered, prepared and prosperous for generations to come.

Shell to shut down Volta EV charging business with 2,000 stations

pulling the plug

A little over two years after buying it for $169 million, Houston-based Shell USA is shutting down its Volta C electric vehicle charging business.

Shell confirmed to AdExchanger that it will dismantle Volta’s network of more than 2,000 EV charging stations this year. A Shell spokesperson said the energy giant is turning its attention to high-speed public charging stations at Shell-branded sites like gas stations and standalone EV hubs.

Around the world, Shell operates more than 70,000 public EV charging stations. In 2024, the company said it was aiming for a global total of about 200,000 charging stations by 2030.

When Shell announced in March 2023 that it had completed its acquisition of Volta, the energy company said it was gaining an EV charging network with more than 3,000 charging stations at places such as shopping centers, grocery stores and pharmacies.

Shell had said that although Volta’s revenue came from advertising on screens at EV charging stations, it planned to increase the number of charging stations that required motorists to pay for power.

Shell explored a sale of the Volta business earlier this year but didn’t find a buyer, according to AdExchanger.
