Chevron, TotalEnergies back energy storage startup's $15.8M series A

money moves

A California startup that's revolutionizing polymer cathode battery technology has announced its series A round of funding with support from Houston-based energy transition leaders.

LiNova Energy Inc. closed a $15.8 million series A round led by Catalus Capital. Saft, a subsidiary of TotalEnergies, which has its US HQ in Houston, and Houston-based Chevron Technology Ventures, also participated in the round with a coalition of other investors.

LiNova will use the funds with its polymer cathode battery to advance the energy storage landscape, according to the company. The company uses a high-energy polymer battery technology that is designed to allow material replacement of the traditional cathode that is made up of cobalt, nickel, and other materials.

The joint development agreement with Saft will have them collaborate to develop the battery technology for commercialization in Saft's key markets.

“We are proud to collaborate with LiNova in scaling up its technology, leveraging the extensive experience of Saft's research teams, our newest prototype lines, and our industrial expertise in battery cell production," Cedric Duclos, CEO of Saft, says in a news release.

Chesapeake Energy backs Houston geothermal tech co. in $17M series A

fresh funding

A Houston geothermal startup has announced the close of its series A round of funding.

Houston-based Sage Geosystems announced the first close of $17 million round led by Chesapeake Energy Corp. The proceeds aim to fund its first commercial geopressured geothermal system facility, which will be built in Texas in Q4 of 2024. According to the company, the facility will be the first of its kind.

The venture is joined by technology investor Arch Meredith, Helium-3 Ventures and will include support from existing investors Virya, LLC, Nabors Industries Ltd., and Ignis Energy Inc.

“The first close of our Series A funding and our commercial facility are significant milestones in our mission to make geopressured geothermal system technologies a reality,” Cindy Taff, CEO of Sage Geosystems, says in a news release. “The success of our GGS technologies is not only critical to Sage Geosystems becoming post-revenue, but it is an essential step in accelerating the development of this proprietary geothermal baseload approach. This progress would not be possible without the ongoing support from our existing investors, and we look forward to continuing this work with our new investors.”

The 3-megawatt commercial facility will be called EarthStore and will use Sage’s technology that harvests energy from pressurized water from underground. The facility will be able to store energy — for short and long periods of time — and can be paired with intermittent renewable energy sources like wind and solar. It will also be able to provide baseload, dispatchable power, and inertia to the electric grid.

In 2023, Sage Geosystems debuted the EarthStore system in a full-scale commercial pilot project in Texas. The pilot produced 200 kilowatt for more than 18 hours, 1 megawatt for 30 minutes, and generated electricity with Pelton turbines. The system had a water loss of less than 2 percent and a round-trip efficiency (RTE) of 70-75.

Houston-based geothermal energy startup releases promising results of Texas pilot

hot off the press

As it seeks an additional $30 million in series A funding, Houston startup Sage Geosystems has released promising results from a test of its technology for underground storage of geothermal energy.

Sage says the pilot project, conducted at a Shell-drilled oil well in the Rio Grande Valley’s Starr County, showed the company’s long-term energy storage can compete on a cost basis with lithium-ion battery storage, hydropower storage, and natural gas-powered peaker plants. Peaker plants supply power during periods of peak energy demand.

Furthermore, Sage’s geothermal technology will provide more power capacity at half the cost of other advanced geothermal systems, the company says.

Sage’s storage system retrofits oil and gas wells with the company’s geothermal technology. But the company says its technology “can be deployed virtually anywhere.”

The system relies on mechanical storage instead of battery storage. In mechanical storage, heat, water, or air works in tandem with compressors, turbines, and other machinery. By contrast, battery storage depends on chemistry to get the job done.

“We have cracked the code to provide the perfect complement to renewable energy. … The opportunities for our energy storage to provide power are significant — from remote mining operations to data centers to solving energy poverty in remote locations,” former Shell executive Cindy Taff, CEO of Sage, says in a September 12 news release.

Sage says its storage capacity can be connected to existing power grids, or it can develop microgrids that harness stored energy.

An August 2023 article in The New York Times explained that Sage “is pursuing fracked wells that act as batteries. When there’s surplus electricity on the grid, water gets pumped into the well. In times of need, pressure and heat in the fractures pushes water back up, delivering energy.”

The pilot project, a joint venture between Sage and the Bureau of Economic Ecology at the University of Texas at Austin, was performed as part of a feasibility study financed by the Air Force. Now that the test results are in, Sage plans to build a prototype geothermal project at the Air Force’s Ellington Field Joint Reserve Base in Houston.

Sage says another feasibility study is underway in the Middle East in partnership with an unnamed oil and gas company.

Founded in 2020, Sage plans to raise another $30 million to accompany its previous series A funding.

The Virya climate fund and Houston-based drilling contractor Nabors Industries helped finance the pilot project in Starr County.

Last year, Sage announced it received an undisclosed amount of equity from Houston-based Ignis H2 Energy, a geothermal exploration and development company, and Dutch energy company Geolog International. Also last year, Sage said Nabors and Virya had teamed up for a $12 million investment in the startup.

Greentown names 5 climatech startups to manufacturing accelerator

Catalyst Cohort

Greentown Labs has named five climatech startups to its Go Make 2026 cohort, including one from Houston.

Greentown Go Make 2026 is in partnership with Shell Catalysts & Technologies and Technip Energies. Startups will be able to collaborate with leadership from Shell and Technip and have opportunities to work directly with their process engineering teams and develop potential partnerships, pilots and demonstrations, according to Greentown.

This year's manufacturing cohort focuses specifically on process technology and catalytic innovations, which, according to Greentown, have the potential to be a "critical enabler of the global energy transition." Greentown shares that 90 percent of chemical processes depend on catalysis, but traditional methods rely on fossil fuels and consume significant amounts of energy.

“Catalysis underpins the majority of industrial chemical processes, which together account for a significant share of global emissions, making it a critical lever for reducing carbon intensity while improving performance,” Georgina Campbell Flatter, CEO of Greentown, said in a news release. “Greentown Go Make 2026 is designed to close the gap between breakthrough innovation and industrial deployment. By connecting startups with Shell and Technip Energies’ technical expertise and global scale, we’re helping accelerate solutions that improve efficiency and drive industrial decarbonization.”

The five Greentown Go Make 2026 companies include:

  • Houston-based Biosimo, which makes scalable biochemicals from ethanol
  • Missouri-based Catalyxx, which transforms bioethanol into drop-in, cost-competitive, carbon-negative chemicals
  • Sydney, Australia-based HydGene Renewables, which produces low-carbon hydrogen and industrial chemicals from waste biomass
  • Switzerland-based TreaTech, which turns waste into renewable gas, water and minerals through catalytic hydrothermal gasification
  • California-based Unifuel, which has developed a chemical technology platform to make sustainable aviation fuel, renewable gasoline and other renewable chemicals

The cohort will be celebrated at a kickoff event in Houston at The Ion on June 9.

In addition to Greentown Go Make, Greentown also runs its Go Move (transportation), Go Energize (energy and electricity), Go Build (buildings), and Go Grow (food and agriculture) cohort-based programs. The climatech incubator announced its Go Build 2026 cohort in March. Read more here.

Houston developer launches AI-powered water platform to boost efficiency

eyes on AI

Houston real estate company McCord Development has launched an artificial-Intelligence-run water management platform, MizuWatch.

MizuWatch aims to help operators, districts, and municipalities detect leaks faster, reduce water loss and improve efficiency, according to the company. MizuWatch pulls data from supply sources, smart meters, historical usage and maintenance records, and combines them into a single platform. The AI system also uses visual mapping and digital twin technology to deliver near-real-time system insights.

“MizuWatch brings the right data together daily, so teams can see what’s happening now, intervene earlier and focus their resources where they have the greatest impact,” Jerzy Wielgus, chief product officer for MizuWatch, said in a news release.

MizuWatch was built to “scale across geographies and system sizes to help assist with water scarcity, aging infrastructure, and operational complexity,” according to the company. It was developed at Houston’s Generation Park, McCord’s 4,300-acre master planned commercial district. McCord was able to pilot the platform onsite to help manage its complex, real-world water systems at scale.

“Resilient infrastructure is a key factor for the companies choosing Generation Park,” Ryan McCord, CEO of McCord Development and Founder & CEO of MizuWatch, added in the release. “We made the decision to deploy smart meters, but no one knew how to use the data they generate. This is an opportunity across all infrastructure where sensors are deployed. What started as an internal solution has become a platform we believe can help stakeholders everywhere be more efficient in their operations, investment, and compliance.”

Last fall, Eli Lilly and Co. selected Generation Park for its $6.5 billion manufacturing plant. More than 300 locations in the U.S. competed for the factory. Bristol Myers Squibb Co., another pharmaceutical giant, also announced it is considering Generation Park for a new manufacturing hub earlier this month.

Oil giant BP ousts new chairman over serious conduct concerns

Sudden Exit

BP has ousted its chairman over what it called serious concerns related to “important governance standards, oversight and conduct.”

The departure was abrupt and unexpected, with Albert Manifold having been appointed to the position late last year.

“Albert has helped bring a welcome focus and pace to BP’s transformation," Amanda Blanc, senior independent director, said in a statement Tuesday, May 26. "However, the board has been surprised and disappointed to learn of governance oversight and conduct issues it deems unacceptable and has taken decisive action.”

BP's board named Ian Tyler as interim chair, effective immediately.

BP, based in London and with North American headquarters in Houston, is a “supermajor,” one of the five largest oil production and exploration companies in the world when measured by revenue and profit.

Manifold, who had been the top executive at Dublin-based global building materials company CRH for 10 years, became the chair at BP in October. BP was looking for someone to revamp the oil giant and went with an industry outsider in Manifold, who had made major strategic changes at CRH.

After a new focus on renewable energy at BP in 2020, by 2025 the company was seeking a return to its roots. BP's hard reset was criticized by environmentalists, as well as some shareholders.

CEO Murray Auchincloss said last year that optimism over opportunities in renewable energy was misplaced, with the company moving “too far and too fast.”

Changes in leadership at BP in recent years has been tumultuous.

CEO Bernard Looney resigned in late 2023 after BP determined that he had misled the company over his past relationships with colleagues.

Auchincloss stepped down in December, and the company named Meg O'Neill as his successor.

Manifold’s was challenged almost immediately when shareholders defeated company resolutions this spring that would have allowed BP to reduce climate reporting requirements and move its annual meetings fully online. Some 18% of shareholders voted against Manifold’s election as chairman, a high level of opposition for an appointment that is generally rubber stamped by investors.

Legal & General, one of Britain’s largest insurers and investment companies, said at the time that Manifold was responsible for resolutions that would have had “a negative impact on shareholders’ insight into how the company is addressing financially material long-term risks, and seizing long-term value creation opportunities, associated with the energy transition,” the Times of London reported on April 23.

Glass Lewis, an influential shareholder advisor, urged investors to vote against Manifold’s election. It held that BP took “unprecedented action” by refusing to consider a resolution from a group of climate activists and pension funds hoping to force the board to create an alternative strategy should demand for fossil fuels decline, the Times reported.

Like other big oil companies, BP has struggled with falling demand in recent years.

BP’s 2025 earnings fell 16% from a year earlier to $7.49 billion as the price of Brent crude, a benchmark for international oil prices, dropped 16.9%. The company’s preferred measure of earnings is underlying replacement cost profit, which adjusts for one-time items and fluctuations in the market value of inventories. Net income plunged 86% to $55 million.

Last year there were media reports that British oil giant Shell was in talks to buy rival BP. Shell denied the reports at the time.

The search for a new chair is underway, BP said Tuesday. Shares of BP Plc slid nearly 5% in midday trading on the NYSE.
