Houston-based clean energy company Intersect Power has wrapped up $837 million in financing for the construction and operation of three standalone battery energy storage systems in Texas.

The money came in the form of debt financing, construction debt, and tax equity. The projects qualify for tax credits under the federal Inflation Reduction Act. Backers of the financing include Deutsche Bank, Morgan Stanley, and affiliates of HPS Investment Partners.

All three storage systems — Lumina I, Lumina II, and Radian — are expected to be online this year. Each system will be capable of storing 320 megawatts of solar power with a two-hour duration.

“Batteries will be a vital part of the energy transition and are the perfect complement to the billions of dollars of solar generation that we are building in California and Texas,” Sheldon Kimber, founder and CEO of Intersect, says in a news release.

Kimber says the storage systems will help Intersect Power triple the size of its portfolio over the next three years.

Intersect’s portfolio features 2.2 gigawatts of solar projects that are already operating, and 2.4 gigawatt hours of storage being operated or built. The company was founded in 2016.

Intersect recently signed a deal with Tesla Energy for 15.2 gigawatt hours of Megapack battery energy storage systems. The contract, which will deliver systems for Intersect projects in Texas and California, ends in 2030.

Experts: To power an energy revolution, a financing evolution is needed

guest column

Texas is a national leader in wind and solar, generating more energy in these categories than any other state since 2006 and double that of next placed California. As investment in renewable energy continues to skyrocket, the limitations of the 19th-century grid prevent the industry from realizing the benefits of this 21st-century technology.

For years, Texas has grappled with insufficient infrastructure for its current mix of energy sources, which includes surging renewables. The Alternating Current (AC) grid — the standard since the 1800s — requires matching supply and demand in real-time to maintain a stable frequency, which is complex and costly, especially with renewable energy when the sun doesn’t always shine and the wind doesn’t always blow.

Startup firms are busy developing technologies to solve this issue. For example, it’s possible to modernize the AC grid to control the voltage of the distribution network precisely, to ensure fast adjustments to demand, and to adapt to changes in supply from renewables. Enoda, a U.K.-based scale-up, is an example of an innovative company developing and delivering technology to enable the AC grid to accommodate much higher levels of renewable energy and electrification.

Equally important to these technical innovations are innovations in financing for energy startups. On two levels, investors in Houston and across Texas are proving to be transformational partners to finance and grow energy hardware startups.

1. Innovative Funding Structures

Because of the long timelines, hardware investing requires, in part, more patient capital than the typical Silicon Valley venture capital model prevalent in startup investments. Their playbook is best suited for software companies that develop new features in weeks or months. Energy hardware startups require a longer timeline because of the far greater complexity and upfront capital outlay.

Texas investment firms and family offices are, however, accustomed to investing in complex energy projects with longer development timelines. This complexity presents a high barrier to entry for competitors, which significantly increases the upside potential that risk-capital investors seek should the innovation find market traction. At the same time, up-front capital requirements have decreased considerably, making hardware more appealing to investors.

2. Visionary partnership

Attracting investors and demonstrating early-stage traction differs for hardware companies because of the lengthy pre-revenue R&D process. Software innovators can launch with a minimum viable product, gain a few early customers, and then grow incrementally. By contrast, energy hardware technology must be fully developed from launch. Each Enoda PRIME exchanger, from the first unit sold, represents a piece of critical infrastructure on which households will rely for their electricity supply for its 30-year lifespan. For venture investors who focus on software, it’s easy to assess the health of a software company based on well-established metrics related to customer growth and the cost of customer acquisition.

Hardware investing requires investors to have a much deeper understanding of the problem being solved and assess the quality of the solution objectively rather than rely on early customers for a minimum viable product. Texas investors have been quick to understand the problems that the energy industry must solve around energy balancing and keeping the frequency of a system stable in order to grow renewable energy. Why the keen insight? Because that problem is being solved today by gas power plants. A visionary investor with many years of deep industry perspective is far more likely to appreciate that than a VC firm looking across many industries based on a standard set of metrics.

Visionary partnership is precisely what energy startups need because it’s important not to evaluate the company as it is today but what it will be in five years. Hardware startups need visionary investor partners who understand the importance of parallel pathing fundamental innovation, product development and delivery, and customer development to grow and succeed. Hardware startups succeed only when they can do these things simultaneously—and require investors who can imagine a possible future and understand the path to reach it.

Changing the way investment works

Many energy startups are worthy inheritors of Houston’s bold entrepreneurial spirit that led to technological innovations like deep-sea drilling and hydraulic fracturing. They will continue to need equally bold investors who recognize the world of opportunities at their doorstep.

money moves

A Houston company that develops standalone battery energy storage systems has reportedly secured $1.8 billion in new financing for a handful of ongoing projects — most of which are in Texas.

"Over the last year, Plus Power has raised an unparalleled amount of capital for standalone storage projects from a wide range of leading energy project finance banks and investors," Josh Goldstein, CFO of Plus Power, says in a news release. "This capital will support the ongoing buildout of the largest and most diverse portfolio of standalone storage projects in the U.S. The scale highlights our first-mover advantage in bringing high-quality projects to market as well as the tremendous work by our fantastic team."

The funding will be distributed to the following projects, which are expected to have a total of 1,040 megawatts of capacity, according to the release:

  • The 250-megawatt Sierra Estrella Energy Storage facility in Avondale, Arizona, west of Phoenix will use $707 million of the financing — $202 million of tax equity and a $505 million construction, term loan, and letter of credit facility from Bank of America. Expected to deliver by summer of next year, the 11-acre facility will be the largest to date for a standalone energy storage project, according to Plus Power.
  • $212.2 million of tax equity financing from Foss & Company, as well as $276 million of construction and term financing, for the 300 MW / 600 MWh Rodeo Ranch Energy Storage facility in Pecos.
  • $196 million of construction and term financing for the 200 MW / 400 MWh Ebony Energy Storage facility in Comal County, northeast of San Antonio.
  • $200 million of construction and term financing for the 200 MW / 400 MWh Anemoi Energy Storage facility in Hidalgo County, on the Mexican border northwest of Matamoros.
  • $196 million construction, term loan and letter of credit facility for the 90 MW / 360 MWh Superstition Energy Storage project in Gilbert, southeast of Phoenix.

The $884 million committed to three new standalone storage facilities in Texas bring Plus Power's current ERCOT portfolio to 800 MW. Deutsche Bank and First Citizens Bank were the coordinating lead arrangers, per the news release.

"Plus Power is a market leader in the battery energy storage sector and we are honored to have collaborated with them on these breakthrough financings," Jeremy Eisman, managing director and head of Infrastructure & Energy Financing at Deutsche Bank, says in a statement. "We acknowledge the important role that battery storage plays in ensuring a clean and reliable electric grid and look forward to continuing to support the Plus Power team's continued growth in this sector."

Plus Power's portfolio includes large-scale lithium-ion battery systems across 25 states and Canada. The company reports that three of the projects will be completed before next year's summer heat rolls back in.

Originally founded in San Francisco in 2018, Plus Power moved its HQ to Houston last year. The company recently signed a lease for nearly 7,000 square feet at Three Hughes Landing in The Woodlands. The company previously was based in coworking space at the Rayford Office Park in Spring.

Fervo named to prestigious list of climate tech companies to watch

top honor

Houston-based Fervo Energy has received yet another accolade—MIT Technology Review named the geothermal energy startup to its 2025 list of the 10 global climatetech companies to watch.

Fervo, making its second appearance on the third annual list, harnesses heat from deep below the ground to generate clean geothermal energy, MIT Technology Review noted. Fervo is one of four U.S. companies to land on the list.

Fervo “uses fracking techniques to create geothermal reservoirs capable of delivering enough electricity to power massive data centers and hundreds of thousands of homes,” MIT Technology Review said.

MIT Technology Review said it produces the annual list to draw attention to promising climatetech companies that are working to decarbonize major sectors of the economy.

“Though the political and funding landscape has shifted dramatically in the US since the last time we put out this list,” MIT Technology Review added, “nothing has altered the urgency of the climate dangers the world now faces — we need to rapidly curb greenhouse gas emissions to avoid the most catastrophic impacts of climate change.”

In addition to MIT Technology Review’s companies-to-watch list, Fervo has appeared on similar lists published by Inc.com, Time magazine and Climate Insider.

In an essay accompanying MIT Technology Review’s list, Microsoft billionaire Bill Gates said his Breakthrough Energy Ventures investment group has invested in more than 150 companies, including Fervo and another company on the MIT Technology Review list, Redwood Materials.

In his essay, Gates wrote that ingenuity is the best weapon against climate change.

Yet climate technology innovations “offer more than just a public good,” he said. “They will remake virtually every aspect of the world’s economy in the coming years, transforming energy markets, manufacturing, transportation, and many types of industry and food production. Some of these efforts will require long-term commitments, but it’s important that we act now. And what’s more, it’s already clear where the opportunities lie.”

In a recent blog post highlighting Fervo, Gates predicted geothermal will eventually supply up to 20 percent of the world’s electricity, up from his previous estimate of as much as 5 percent.

Fervo is one of the pioneers in geothermal energy. Gates and other investors have pumped $982 million into Fervo since its founding in 2017. With an estimated valuation of $1.4 billion, Fervo has achieved unicorn status, meaning its valuation as a private company exceeds $1 billion.

Aside from Breakthrough Energy Ventures, oilfield services provider Liberty Energy is a Fervo investor. U.S. Energy Secretary Chris Wright was chairman and CEO of Denver-based Liberty Energy before assuming his federal post.

Axios reported on Oct. 1 that Fervo is raising a $300 million series E round, which would drive up the startup’s valuation. News of the $300 million round comes as the company gears up for a possible IPO, according to Axios.

Fervo co-founder and CEO Tim Latimer told Axios this spring that a potential IPO is likely in 2026 or 2027. Ahead of an IPO, the startup is aiming for a $2 billion to $4 billion valuation, Axios reported.

The first phase of Fervo’s marquee Cape Station geothermal energy plant in Utah is scheduled to go online next year, with the second phase set to open in 2028. Once it’s completed, the plant will be capable of generating 500 megawatts of power. This summer, the startup said it secured $205.6 million in capital to finance construction of the plant.

Rice University team develops eco-friendly method to destroy 'forever chemicals' in water

clean water research

Rice University researchers have teamed up with South Korean scientists to develop the first eco-friendly technology that captures and destroys toxic “forever chemicals,” or PFAS, in water.

PFAS have been linked to immune system disruption, certain cancers, liver damage and reproductive disorders. They can be found in water, soil and air, as well as in products like Teflon pans, waterproof clothing and food packaging. They do not degrade easily and are difficult to remove.

Thus far, PFAS cleanup methods have relied on adsorption, in which molecules cling to materials like activated carbon or ion-exchange resins. But these methods tend to have limited capacity, low efficiency, slow performance and can create additional waste.

The Rice-led study, published in the journal Advanced Materials, centered on a layered double hydroxide (LDH) material made from copper and aluminum that could rapidly capture PFAS and be used to destroy the chemicals.

The study was led by Rice professor Youngkun Chung, a postdoctoral fellow under the mentorship of Michael S. Wong. It was conducted in collaboration with Seoktae Kang, professor at the Korea Advanced Institute of Science and Technology, and Keon-Ham Kim, professor at Pukyung National University, who first discovered the LDH material.

The team evaluated the LDH material in river water, tap water and wastewater. And, according to Rice, that material’s unique copper-aluminum layers and charge imbalances created an ideal binding environment to capture PFAS molecules.

“To my astonishment, this LDH compound captured PFAS more than 1,000 times better than other materials,” Chung, lead author of the study and now a fellow at Rice’s WaTER (Water Technologies, Entrepreneurship and Research) Institute and Sustainability Institute, said in a news release. “It also worked incredibly fast, removing large amounts of PFAS within minutes, about 100 times faster than commercial carbon filters.”

Next, Chung, along with Rice professors Pedro Alvarez and James Tour, worked to develop an eco-friendly, sustainable method of thermally decomposing the PFAS captured on the LDH material. They heated saturated material with calcium carbonate, which eliminated more than half of the trapped PFAS without releasing toxic by-products.

The team believes the study’s results could potentially have large-scale applications in industrial cleanups and municipal water treatments.

“We are excited by the potential of this one-of-a-kind LDH-based technology to transform how PFAS-contaminated water sources are treated in the near future,” Wong added in the news release. “It’s the result of an extraordinary international collaboration and the creativity of young researchers.”
