Thanks to recently announced funding, the power grid for the territory served by the Electric Reliability Council of Texas (ERCOT) will be connected to grids in other states.

Officials hope building a 320-mile transmission line that connects the ERCOT electric grid to electric grids in the Southeast will prevent power outages like the massive blackout that occurred in 2022 when a winter storm blasted Texas.

San Francisco-based Pattern Energy says its Southern Spirit project will cost more than $2.6 billion. Full-scale construction is supposed to get underway in 2028, and the project is set to go online in 2031.

The U.S. Department of Energy recently approved up to $360 million for the transmission project. The transmission line will stretch from Texas’ border with Louisiana to Mississippi. It’ll supply about 3,000 megawatts of electricity in either direction. That’s enough power for about 750,000 residential customers during ERCOT’s peak hours.

ERCOT’s more than 54,100 miles of transmission lines supply power to about 90 percent of Texans.

“The U.S. transmission network is the backbone of our nation’s electricity system. Though our grid has served U.S. energy needs for more than a century, our country’s needs are changing,” David Turk, under secretary at the Department of Energy, says in a news release.

“DOE’s approach to deploying near-term solutions and developing long-term planning tools will ensure our electric grid is more interconnected and resilient than ever before,” Turk adds, “while also supporting greater electricity demand.”

The other three projects that recently received funding from the DOE include:

  • Aroostook Renewable Project, which will construct a new substation in Haynesville, Maine, and a 111-mile transmission line connecting to a substation in Pittsfield, Maine.
  • Cimarron Link, a 400-mile HVDC transmission line from Texas County, Oklahoma to Tulsa, Oklahoma
  • Southline, which will construct a 108-mile transmission line between Hidalgo County, New Mexico, and Las Cruces, New Mexico. The DOE previously supported a 175-mile line from Hidalgo County, New Mexico, to Pima County, Arizona, in Southline Phase 1 on the first round of the Transmission Facilitation Program.

This month's funding completes the $2.5 billion in awards from the Transmission Facilitation Program which is administered through the Building a Better Grid Initiative that launched in January 2022. Its mission has been to develop nationally significant transmission lines, increase resilience by connecting regions of the country and improve access to clean energy sources, according to the DOE.

Earlier this year, ERCOT, which manages 90 percent of Texas’ power supply, forecasted a major spike in demand for electricity over the next five to seven years

Meta taps Houston geothermal co. to power data center growth with clean energy

big tech

A Houston company has signed a new agreement with Meta Platforms Inc. — Facebook's parent company — to power the tech giant's data center growth.

Houston-based Sage Geosystems agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta. The companies made the announcement this week at the United States Department Energy’s Catalyzing Next Generation Geothermal Development Workshop.

The deal is significant because it's the first next-generation geothermal project located to the east of the Rocky Mountains, the companies report in a news release.

“This announcement is the perfect example of how the public and private sector can work together to make the clean energy transition a reality,” Cindy Taff, CEO of Sage Geosystems, says in the release. “We are thrilled to be at the forefront of the next generation of geothermal technology and applaud the DOE for supporting the commercialization of innovation solutions.

"As energy demand continues to grow, the need for reliable, resilient and sustainable power is paramount and our partnership with Meta underscores the critical need for innovative and sustainable energy solutions like ours,” she continues.

The project's first phase will aim to be operating in 2027. The plans reflect how geothermal is being recognized as a growing carbon-free energy source in the country, and how Meta is committed to clean energy initiatives.

“The U.S. has seen unprecedented growth in demand for energy as our economy grows, the manufacturing sector booms thanks to the Biden-Harris Administration’s Investing in America agenda, and new industries like AI expand,” U.S. Energy Deputy Secretary David Turk says. “The Administration views this increased demand as a huge opportunity to add more clean, firm power to the grid and geothermal energy is a game-changeras we work to grow our clean power supply.”

Sage's technology — called Geopressured Geothermal System — works deep in the earth to develop energy storage and geothermal baseload power.

“Meta thanks the Department of Energy’s leadership on promoting and supporting the exploration of new energy sources like geothermal," Urvi Parekh, head of renewable energy at Meta, says. "That leadership supports Meta’s goal to enable the addition of reliable, affordable, and carbon-free power to the grid with this geothermal energy deal. We are excited to partner with such an innovative company like Sage Geosystems that is a proven leader in geothermal development on this project and beyond.”

Sage recently teamed up with a utility provider for an energy storage facility in the San Antonio metro area to build its three-megawatt EarthStore facility.

The company is also working on an exploratory geothermal project for the Army’s Fort Bliss post in Texas, which is the third U.S. Department of Defense geothermal initiative in the Lone Star State.

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.

Hosted by Jason Ethier and Nada Ahmed, the Digital Wildcatters’ podcast, Energy Tech Startups, delves into Houston's pivotal role in the energy transition, spotlighting entrepreneurs and industry leaders shaping a low-carbon future.


Gold H2 harvests clean hydrogen from depleted California reservoirs in first field trial

breakthrough trial

Houston climatech company Gold H2 completed its first field trial that demonstrates subsurface bio-stimulated hydrogen production, which leverages microbiology and existing infrastructure to produce clean hydrogen.

Gold H2 is a spinoff of another Houston biotech company, Cemvita.

“When we compare our tech to the rest of the stack, I think we blow the competition out of the water," Prabhdeep Singh Sekhon, CEO of Gold H2 Sekhon previously told Energy Capital.

The project represented the first-of-its-kind application of Gold H2’s proprietary biotechnology, which generates hydrogen from depleted oil reservoirs, eliminating the need for new drilling, electrolysis or energy-intensive surface facilities. The Woodlands-based ChampionX LLC served as the oilfield services provider, and the trial was conducted in an oilfield in California’s San Joaquin Basin.

According to the company, Gold H2’s technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

“This field trial is tangible proof. We’ve taken a climate liability and turned it into a scalable, low-cost hydrogen solution,” Sekhon said in a news release. “It’s a new blueprint for decarbonization, built for speed, affordability, and global impact.”

Highlights of the trial include:

  • First-ever demonstration of biologically stimulated hydrogen generation at commercial field scale with unprecedented results of 40 percent H2 in the gas stream.
  • Demonstrated how end-of-life oilfield liabilities can be repurposed into hydrogen-producing assets.
  • The trial achieved 400,000 ppm of hydrogen in produced gases, which, according to the company,y is an “unprecedented concentration for a huff-and-puff style operation and a strong indicator of just how robust the process can perform under real-world conditions.”
  • The field trial marked readiness for commercial deployment with targeted hydrogen production costs below $0.50/kg.

“This breakthrough isn’t just a step forward, it’s a leap toward climate impact at scale,” Jillian Evanko, CEO and president at Chart Industries Inc., Gold H2 investor and advisor, added in the release. “By turning depleted oil fields into clean hydrogen generators, Gold H2 has provided a roadmap to produce low-cost, low-carbon energy using the very infrastructure that powered the last century. This changes the game for how the world can decarbonize heavy industry, power grids, and economies, faster and more affordably than we ever thought possible.”
