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.

Rice University played host to the first-of-its-kind event from the Department of Energy’s Advanced Research Projects Agency-Energy, or ARPA-E, earlier this month in which the governmental agency announced $100 million in funding for its SCALEUP program.

Dubbed “ARPA-E on the Road: Houston,” the event welcomed more than 100 energy innovators to the Hudspeth Auditorium in Rice’s Anderson-Clarke Center on June 8. Evelyn Wang, director of ARPA-E, announced the funding, which represents the third installment from the agency for its program SCALEUP, or Seeding Critical Advances for Leading Energy technologies with Untapped Potential, which supports the commercialization of clean energy technology.

The funding is awarded to previous ARPA-E awardees with a "viable road to market" and "ability to attract private sector investments," according to a statement from the Department of Energy. Previous funding was granted in 2019 and 2021.

"ARPA-E’s SCALEUP program has successfully demonstrated what can happen when technical experts are empowered with the commercialization support to develop a strong pathway to market” Wang said. “I’m excited that we are building on the success of this effort with the third installment of SCALEUP, and I look forward to what the third cohort of teams accomplish.”

Rice Vice President for Research Ramamoorthy Ramesh also spoke at the event on how Rice is working to make Houston a leader in energy innovation. Joe Zhou, CEO of Houston-based Quidnet Energy, also spoke on a panel about how ARPA-E funding benefited his company along with Oregon-based Onboard Dynamics’s CEO Rita Hansen and Massachusetts-based Quaise Energy’s CEO Carlos Araque.

Attendees were able to ask questions to Wang and ARPA-E program directors about the agency’s funding approach and other topics at the event.

Houston energy innovators have benefited from programs like SCALEUP.

Quidnet Energy received $10 million in funding from ARPA-E as part of its SCALEUP program in 2022. The company's technology can store renewable energy for long periods of time in large quantities.

In January, Houston-based Zeta Energy also announced that it has secured funding from ARPA-E. The $4 million in funding came from the agency's Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program. Zeta Energy is known for its lithium sulfur batteries

Houston energy storage startup secures $10M in federal funding

seeing green

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.

How Planckton Data is building the sustainability label every industry will need

now streaming

There’s a reason “carbon footprint” became a buzzword. It sounds like something we should know. Something we should measure. Something that should be printed next to the calorie count on a label.

But unlike calories, a carbon footprint isn’t universal, standardized, or easy to calculate. In fact, for most companies—especially in energy and heavy industry—it’s still a black box.

That’s the problem Planckton Data is solving.

On this episode of the Energy Tech Startups Podcast, Planckton Data co-founders Robin Goswami and Sandeep Roy sit down to explain how they’re turning complex, inconsistent, and often incomplete emissions data into usable insight. Not for PR. Not for green washing. For real operational and regulatory decisions.

And they’re doing it in a way that turns sustainability from a compliance burden into a competitive advantage.

From calories to carbon: The label analogy that actually works

If you’ve ever picked up two snack bars and compared their calorie counts, you’ve made a decision based on transparency. Robin and Sandeep want that same kind of clarity for industrial products.

Whether it’s a shampoo bottle, a plastic feedstock, or a specialty chemical—there’s now consumer and regulatory pressure to know exactly how sustainable a product is. And to report it.

But that’s where the simplicity ends.

Because unlike food labels, carbon labels can’t be standardized across a single factory. They depend on where and how a product was made, what inputs were used, how far it traveled, and what method was used to calculate the data.

Even two otherwise identical chemicals—one sourced from a refinery in Texas and the other in Europe—can carry very different carbon footprints, depending on logistics, local emission factors, and energy sources.

Planckton’s solution is built to handle exactly this level of complexity.

AI that doesn’t just analyze

For most companies, supply chain emissions data is scattered, outdated, and full of gaps.

That’s where Planckton’s use of AI becomes transformative.

  • It standardizes data from multiple suppliers, geographies, and formats.
  • It uses probabilistic models to fill in the blanks when suppliers don’t provide details.
  • It applies industry-specific product category rules (PCRs) and aligns them with evolving global frameworks like ISO standards and GHG Protocol.
  • It helps companies model decarbonization pathways, not just calculate baselines.

This isn’t generative AI for show. It’s applied machine learning with a purpose: helping large industrial players move from reporting to real action.

And it’s not a side tool. For many of Planckton’s clients, it’s becoming the foundation of their sustainability strategy.

From boardrooms to smokestacks: Where the pressure is coming from

Planckton isn’t just chasing early adopters. They’re helping midstream and upstream industrial suppliers respond to pressure coming from two directions:

  1. Downstream consumer brands—especially in cosmetics, retail, and CPG—are demanding footprint data from every input supplier.
  2. Upstream regulations—especially in Europe—are introducing reporting requirements, carbon taxes, and supply chain disclosure laws.

The team gave a real-world example: a shampoo brand wants to differentiate based on lower emissions. That pressure flows up the value chain to the chemical suppliers. Who, in turn, must track data back to their own suppliers.

It’s a game of carbon traceability—and Planckton helps make it possible.

Why Planckton focused on chemicals first

With backgrounds at Infosys and McKinsey, Robin and Sandeep know how to navigate large-scale digital transformations. They also know that industry specificity matters—especially in sustainability.

So they chose to focus first on the chemicals sector—a space where:

  • Supply chains are complex and often opaque.
  • Product formulations are sensitive.
  • And pressure from cosmetics, packaging, and consumer brands is pushing for measurable, auditable impact data.

It’s a wedge into other verticals like energy, plastics, fertilizers, and industrial manufacturing—but one that’s already showing results.

Carbon accounting needs a financial system

What makes this conversation unique isn’t just the product. It’s the co-founders’ view of the ecosystem.

They see a world where sustainability reporting becomes as robust as financial reporting. Where every company knows its Scope 1, 2, and 3 emissions the way it knows revenue, gross margin, and EBITDA.

But that world doesn’t exist yet. The data infrastructure isn’t there. The standards are still in flux. And the tooling—until recently—was clunky, manual, and impossible to scale.

Planckton is building that infrastructure—starting with the industries that need it most.

Houston as a launchpad (not just a legacy hub)

Though Planckton has global ambitions, its roots in Houston matter.

The city’s legacy in energy and chemicals gives it a unique edge in understanding real-world industrial challenges. And the growing ecosystem around energy transition—investors, incubators, and founders—is helping companies like Planckton move fast.

“We thought we’d have to move to San Francisco,” Robin shares. “But the resources we needed were already here—just waiting to be activated.”

The future of sustainability is measurable—and monetizable

The takeaway from this episode is clear: measuring your carbon footprint isn’t just good PR—it’s increasingly tied to market access, regulatory approval, and bottom-line efficiency.

And the companies that embrace this shift now—using platforms like Planckton—won’t just stay compliant. They’ll gain a competitive edge.
