The Woodlands-based Plus Power has collected an estimated $98 million tax equity investment for its 200-megawatt Ebony Energy Storage facility near San Antonio.

Plus Power says the investment from Solana Beach, California-based Greenprint Capital Management will help stabilize the Energy Reliability Council of Texas (ERCOT) power system “during dynamic summer demand and cold winter storms while helping to integrate more renewable energy into the grid.”

The storage facility, being built on 13 acres in Comal County, is scheduled to come online this spring.

Peter DeFazio, managing director of Greenprint, calls Plus Power “a first mover” among owner-operators of standalone battery energy storage facilities in the U.S. Plus Power owns a portfolio of large-scale lithium-ion battery systems in more than 25 states and Canada.

“As the state and the country experience increasingly extreme temperatures, we are proud that our projects can provide grid services that will help ERCOT increase reliability and meet abnormally high demand,” says Josh Goldstein, chief financial officer of Plus Power.

By this summer, Plus Power expects to be operating four storage plants in the ERCOT market with 800 megawatts of total capacity.

Plus Power announced in 2023 that it completed a $1.8 billion financing for Ebony and four other projects in Texas and Arizona. The financing included $196 million in construction and term financing for the Comal County project.

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.

Oxy's $1.3B Texas carbon capture facility on track to launch this year

gearing up

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.

Fervo Energy selects Baker Hughes to provide supply geothermal tech for power plants

geothermal deal

Houston-based geothermal energy startup Fervo Energy has tapped Houston-based energy technology company Baker Hughes to supply geothermal equipment for five Fervo power plants in Utah.

The equipment will be installed at Fervo’s Cape Station geothermal power project near Milford, Utah. The project’s five second-phase, 60-megawatt plants will generate about 400 megawatts of clean energy for the grid.

Financial terms of the deal weren’t disclosed.

“Baker Hughes’ expertise and technology are ideal complements to the ongoing progress at Cape Station, which has been under construction and successfully meeting project milestones for almost two years,” says Tim Latimer, co-founder and CEO of Fervo. “Fervo designed Cape Station to be a flagship development that's scalable, repeatable, and a proof point that geothermal is ready to become a major source of reliable, carbon-free power in the U.S.”

Cape Station is permitted to deliver about two gigawatts of geothermal power. The first phase of the project will supply 100 megawatts of power to the grid beginning in 2026. The second phase is scheduled to come online by 2028.

“Geothermal power is one of several renewable energy sources expanding globally and proving to be a vital contributor to advancing sustainable energy development,” Baker Hughes Chairman and CEO Lorenzo Simonelli says. “By working with a leader like Fervo Energy and leveraging our comprehensive portfolio of technology solutions, we are supporting the scaling of lower-carbon power solutions that are integral to meet growing global energy demand.”

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company has surpassed $1 billion. In March, Axios reported Fervo is targeting a $2 billion to $4 billion valuation in an IPO.

Over the course of eight years, Fervo has raised almost $1 billion in capital, including equity and debt financing. This summer, the company secured a $205.5 million round of capital.

Houston-area sustainable steel company emerges from stealth with $17M in VC funding

heavy metals

Conroe-based Hertha Metals, a producer of substantial steel, has hauled in more than $17 million in venture capital from Khosla Ventures, Breakthrough Energy Fellows, Pear VC, Clean Energy Ventures and other investors.

The money has been put toward the construction and the launch of its 1-metric-ton-per-day pilot plant in Conroe, where its breakthrough in steelmaking has been undergoing tests. The company uses a single-step process that it claims is cheaper, more energy-efficient and equally as scalable as conventional steelmaking methods. The plant is fueled by natural gas or hydrogen.

The company, founded in 2022, plans to break ground early next year on a new plant. The facility will be able to produce more than 9,000 metric tons of steel per year.

Hertha said in a news release that its process, which converts low-grade iron ore into molten steel or high-purity iron, “doesn’t just materially lower cost and energy use — it fundamentally expands our capacity to produce iron and steel at scale, by unlocking a wider range of iron ore feedstocks.”

Laureen Meroueh, founder and CEO of Hertha, says the company’s process will fill a gap in U.S. steel production.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Meroueh says.

Hertha says it’s in talks with magnet producers — which make permanent magnets and magnetic assemblies from raw materials such as iron — to become a U.S. supplier of high-purity iron. In its next stage of growth, Hertha will aim to operate at a capacity of 500,000 metric tons of steel production per year.

The company won the Department of Energy's Summer Energy Program for Innovation Clusters (EPIC) Startup Pitch Competition last summer. Read more here.
