A Houston-based company that's developing long-duration energy storage solutions announced a $10 million investment and partnership with a Texas corporation.

Quidnet Energy has entered into a strategic partnership with Hunt Energy Network, an affiliate of Dallas-based Hunt Energy that develops and operates distributed energy resources. The two Texas companies will work on a build-transfer program for 300 MW of storage projects that uses Quidnet's Geomechanical Energy Storage technology in the Electric Reliability Council of Texas (ERCOT) grid operating region.

“Hunt Energy Network brings an extensive and proven track record across diverse energy businesses, making them an ideal partner to address the need for large-scale, long-duration energy storage in Texas,” Joe Zhou, CEO of Quidnet Energy, says in a news release. “We’re thrilled to have them as an investor, partner, and board member, and we look forward to jointly advancing the deployment of energy storage solutions, particularly in regions like ERCOT where the need is most pressing.”

Todd Benson, the chief innovation officer of Hunt Energy, will join Quidnet's board of directors as a part of the partnership.

“Quidnet Energy's GES technology presents a unique opportunity to revolutionize energy storage, and we’re excited to invest in a solution that purposefully transforms existing resources to expand access to long-duration storage,” adds Pat Wood, III, CEO of HEN. “ERCOT's growing supply of renewable energy makes this region ideal for the deployment of our technology, and we’re pleased to work with another Texas innovator to build a more resilient grid for all ERCOT customers.”

Quidnet’s technology, which can provide over 10 hours of storage, uses drilling and hydropower machinery to store renewable energy. Essentially, the company, founded in 2013, is using water storage to power carbon-free electric grid approach to energy.

One year ago, Quidnet secured $10 million from the U.S. Department of Energy Advanced Research Projects Agency-Energy, or ARPA-E. Just a few months after that, the company received an additional $2 million from the DOE for its project, entitled "Energy Storage Systems for Overpressure Environments," which is taking place in East Texas.

Houston-based Zeta Energy Corp. has teamed up with an automaker to develop new battery technology.

Zeta Energy and Stellantis N.V. announced a joint development deal to advance battery cell technology for electric vehicle applications that will develop lithium-sulfur EV batteries with gravimetric energy density that can achieve a volumetric energy density comparable to today’s lithium-ion technology. The batteries are targeted to power Stellantis electric vehicles by 2030.

“The combination of Zeta Energy’s lithium-sulfur battery technology with Stellantis’ unrivaled expertise in innovation, global manufacturing and distribution can dramatically improve the performance and cost profile of electric vehicles while increasing the supply chain resiliency for batteries and EVs,” Tom Pilette, CEO of Zeta Energy, says in a news release.

The batteries will be produced using waste materials and methane that boasts lower CO2 emissions than any existing battery technology. Zeta Energy battery technology is intended to be manufacturable within existing gigafactory technology and would leverage an entire domestic supply chain in Europe or North America.

The technology can lead to a significantly lighter battery pack with the same usable energy as contemporary lithium-ion batteries. The companies believe this will enable greater range, improved handling and enhanced performance. The technology has the potential to improve fast-charging speed by up to 50 percent, which can make EV ownership easier.

Lithium-sulfur batteries are expected to cost less than half the price per kilowatt of current lithium-ion batteries according to a news release. Zeta has more than 60 patents on its proprietary lithium-sulfur anode and cathode technologies.

Lighter and more compact EV batteries have become an important design goal for vehicle designers and manufacturers. This objective is similar to what General Motors is doing with prismatic cell technology with LG Energy Solution.

“Our collaboration with Zeta Energy is another step in helping advance our electrification strategy as we work to deliver clean, safe and affordable vehicles,” Ned Curic, Stellantis chief engineering and technology officer, says in the release. “Groundbreaking battery technologies like lithium-sulfur can support Stellantis’ commitment to carbon neutrality by 2038 while ensuring our customers enjoy optimal range, performance and affordability.”

Last year, Zeta Energy announced that it was selected to receive $4 million in federal funding for the development of efficient electric vehicle batteries from the U.S. Department of Energy's ARPA-E Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program.
