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.

Houston energy-focused AI platform raises $5M in Mercury-led seed round

fresh funding

Houston-based Collide, a provider of generative artificial intelligence for the energy sector, has raised $5 million in seed funding led by Houston’s Mercury Fund.

Other investors in the seed round include Bryan Sheffield, founder of Austin-based Parsley Energy, which was acquired by Dallas-based Pioneer Natural Resources in 2021; Billy Quinn, founder and managing partner of Dallas-based private equity firm Pearl Energy Investments; and David Albin, co-founder and former managing partner of Dallas-based private equity firm NGP Capital Partners.

“(Collide) co-founders Collin McLelland and Chuck Yates bring a unique understanding of the oil and gas industry,” Blair Garrou, managing partner at Mercury, said in a news release. “Their backgrounds, combined with Collide’s proprietary knowledge base, create a significant and strategic moat for the platform.”

Collide, founded in 2022, says the funding will enable the company to accelerate the development of its GenAI platform. GenAI creates digital content such as images, videos, text, and music.

Originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing,” the company says it will now shift its focus to rolling out its enterprise-level, AI-enabled solution.

Collide explains that its platform gathers and synthesizes data from trusted sources to deliver industry insights for oil and gas professionals. Unlike platforms such as OpenAI, Perplexity, and Microsoft Copilot, Collide’s platform “uniquely accesses a comprehensive, industry-specific knowledge base, including technical papers, internal processes, and a curated Q&A database tailored to energy professionals,” the company said.

Collide says its approximately 6,000 platform users span 122 countries.

Houston venture firm invests in Virginia fusion power plant company in collaboration with TAMU

fusion funding

Houston-based climate tech venture firm Ecosphere Ventures has partnered with Virginia Venture Partners and Virginia Innovation Partnership Corporation’s venture capital program to invest in Virginia-based NearStar Fusion Inc., which develops fusion energy power plants.

NearStar aims to use its proprietary plasma railgun technology to safely and affordably power baseload electricity on and off the power grid through a Magnetized Target Impact Fusion (MTIF) approach, according to a news release from the company.

NearStar’s power plants are designed to retrofit traditional fossil fuel power plants and are expected to serve heavy industry, data centers and military installations.

“Our design is well-suited to retrofit coal-burning power plants and reuse existing infrastructure such as balance of plant and grid connectivity, but I’m also excited about leveraging the existing workforce because you won’t need PhDs in plasma physics to work in our power plant,” Amit Singh, CEO of NearStar Fusion, said in a news release.

NearStar will also conduct experiments at the Texas A&M Hypervelocity Impact Laboratory (HVIL) in Bryan, Texas, on prototype fuel targets and evolving fuel capsule design. The company plans to publish the results of the experiments along with a concept paper this year. NearStar will work with The University of Alabama in Huntsville (UAH) to develop computer performance models for target implosions.

NearStar’s MTIF approach will utilize deuterium, which is a common isotope of hydrogen found in water. The process does not use tritium, which NearStar believes will save customers money.

“While avoiding tritium in our power plant design reduces scientific gain of the fusion process, we believe the vastly reduced system complexity and cost savings of eliminating complicated supply chains, regulatory oversight, and breeding of tritium allows NearStar to operate power plants more profitably and serve more customers worldwide, ”Douglas Witherspoon, NearStar founder and chief scientist, said in a news release.

Houston’s Ecosphere Ventures invests in climate tech and sustainability innovations from pre-seed to late-seed stages in the U.S. Ecosphere also supports first-time entrepreneurs and technical founders.

Geothermal energy startup's $600M deal fuels surge in Houston VC funding

by the numbers

The venture capital haul for Houston-area startups jumped 23 percent from 2023 to 2024, according to the latest PitchBook-NVCA Venture Monitor.

The fundraising total for startups in the region climbed from $1.49 billion in 2023 to $1.83 billion in 2024, PitchBook-NVCA Venture Monitor data shows.

Roughly half of the 2024 sum, $914.3 million, came in the fourth quarter. By comparison, Houston-area startups collected $291.3 million in VC during the fourth quarter of 2023.

Among the Houston-area startups contributing to the impressive VC total in the fourth quarter of 2024 was geothermal energy startup Fervo Energy. PitchBook attributes $634 million in fourth-quarter VC to Fervo, with fulfillment services company Cart.com at $50 million, and chemical manufacturing platform Mstack and superconducting wire manufacturer MetOx International at $40 million each.

Across the country, VC deals total $209 billion in 2024, compared with $162.2 billion in 2023. Nearly half (46 percent) of all VC funding in North America last year went to AI startups, PitchBook says. PitchBook’s lead VC analyst for the U.S., Kyle Stanford, says that AI “continues to be the story of the market.”

PitchBook forecasts a “moderately positive” 2025 for venture capital in the U.S.

“That does not mean that challenges are gone. Flat and down rounds will likely continue at higher paces than the market is accustomed to. More companies will likely shut down or fall out of the venture funding cycle,” says PitchBook. “However, both of those expectations are holdovers from 2021.”

Blackstone clears major step in acquisition of TXNM Energy

power deal

A settlement has been reached in a regulatory dispute over Blackstone Infrastructure’s pending acquisition of TXNM Energy, the parent company of Texas-New Mexico Power Co. , which provides electricity in the Houston area. The settlement still must be approved by the Public Utility Commission of Texas.

Aside from Public Utility Commission staffers, participants in the settlement include TXNM Energy, Texas cities served by Texas-New Mexico Power, the Texas Office of Public Utility Counsel, Texas Industrial Energy Consumers, Walmart and the Texas Energy Association for Marketers.

Texas-New Mexico Power, based in the Dallas-Fort Worth suburb of Lewisville, supplies electricity to more than 280,000 homes and businesses in Texas. Ten cities are in Texas-New Mexico Power’s Houston-area service territory:

  • Alvin
  • Angleton
  • Brazoria
  • Dickinson
  • Friendswood
  • La Marque
  • League City
  • Sweeny
  • Texas City
  • West Columbia

Under the terms of the settlement, Texas-New Mexico Power must:

  • Provide a $45.5 million rate credit to customers over 48 months, once the deal closes
  • Maintain a seven-member board of directors, including three unaffiliated directors as well as the company’s president and CEO
  • Embrace “robust” financial safeguards
  • Keep its headquarters within the utility’s Texas service territory
  • Avoid involuntary layoffs, as well as reductions of wages or benefits related to for-cause terminations or performance issues

The settlement also calls for Texas-New Mexico Power to retain its $4.2 billion five-year capital spending plan through 2029. The plan will help Texas-New Mexico Power cope with rising demand; peak demand increased about 66 percent from 2020 to 2024.

Citing the capital spending plan in testimony submitted to the Public Utility Commission, Sebastian Sherman, senior managing director of Blackstone Infrastructure, said Texas-New Mexico Power “needs the right support to modernize infrastructure, to strengthen the grid against wildfire and other risks, and to meet surging electricity demand in Texas.”

Blackstone Infrastructure, which has more than $64 billion in assets under management, agreed in August to buy TXNM Energy in a $11.5 billion deal.

Neal Walker, president of Texas-New Mexico Power, says the deal will help his company maintain a reliable, resilient grid, and offer “the financial resources necessary to thrive in this rapidly changing energy environment and meet the unprecedented future growth anticipated across Texas.”

Constellation and Calpine's $26B clean energy megadeal clears final regulatory hurdle

big deal

Baltimore-based nuclear power company Constellation Energy Corp. received final regulatory clearance this month to acquire Houston-based Calpine Corp. for a net purchase price of $26.6 billion.

The acquisition has the potential to create America’s “largest clean energy provider,” the companies reported when the deal was first announced in January.

The Department of Justice approved the acquisition contingent on Calpine divesting several assets, including one in the Houston area.

The company agreed to divest the Jack Fusco Energy Center natural gas-fired combined cycle facility in Richmond, Texas; four generating assets in the Mid-Atlantic region; and other natural gas plants in Pennsylvania and Corpus Christi, Texas.

The Federal Energy Regulatory Commission, the Public Utility Commission of Texas and the New York Public Service Commission previously approved the deal. The companies can move toward closing the acquisition once the court finalizes the stipulation and order.

"We are very pleased to reach a settlement that allows us to bring together two magnificent companies to create a new Constellation with unprecedented scale, talent and capability to better serve our customers and communities while building the foundation for America’s next great era of growth and innovation," Joe Dominguez, president and CEO of Constellation, said in a news release. "We thank the Department for its professionalism and tireless work reviewing this transaction through these many months. It’s now time for us to complete the transaction, welcome our new colleagues from Calpine, and together begin our journey to light the way to a brilliant tomorrow for all."

Andrew Novotny, CEO of Calpine, will continue to lead the Calpine business and Constellation's fleet of natural gas, hydro, solar and wind generation, according to the company. He will report to Dominguez and also serve as senior executive vice president of Constellation Power Operations.

Constellation is considered one of the top clean energy producers in the U.S. Earlier this month, the company was approved to receive a $1 billion loan from the Department of Energy's Energy Dominance Financing Program to restart its 835-megawatt nuclear reactor in Pennsylvania known as Crane Clean Energy Center.

"Work to restart the reactor comes at a time of unprecedented electric demand growth from electrification and the new data centers needed to support a growing digital economy and to help America win the AI race," a news release from the company reads. "Crane will support grid stability by delivering reliable, around-the-clock electric supply."

States brace for Trump's push to make oil drilling cheap again

Energy news

A Republican push to make drilling cheaper on federal land is creating new fiscal pressure for states that depend on oil and gas revenue, most notably in New Mexico as it expands early childhood education and saves for the future.

The shift stems from the sweeping law President Donald Trump signed in July that rolls back the minimum federal royalty rate to 12.5%. That rate — the share of production value companies must pay to the government — held steady for a century under the 1920 Mineral Leasing Act. It was raised to 16.7% under the Biden administration in 2022.

Trump and Republicans in Congress say the rate reset will boost energy production, jobs and affordability as the administration clears the way for expanded drilling and mining on public lands.

States receive nearly half the money collected through federal royalties, depending on where production takes place. The environment and economics research group Resources for the Future estimates a roughly $6 billion drop in collections over the coming decade.

The stakes are highest in New Mexico, the largest recipient of federal mineral lease payments. The state could could forgo $1.7 billion by 2035 and as much as $5.1 billion by 2050, according to calculations by economist Brian Prest at Resources for the Future.

More than one-third of the general fund budget in the Democratically-led state is tied to the oil and gas industry.

“New Mexico’s impact is way bigger than Wyoming or Colorado or North Dakota,” Prest said, “and that’s just because that’s where the action is on new development.”

The effects will unfold gradually, since federal leases allow a 10-year window to begin drilling and production. Still, state officials say they're already prepping for leaner years.

“It all hurts when you’re losing revenues," said Democratic state Sen. George Muñoz of Gallup, who said lawmakers still hope to invest more in mental health care and support Medicaid, even if federal royalty payments decline. “We’ve learned that until the chicken’s got feathers, we’re not even looking at it."

The higher federal royalty rate was in place for roughly three years while leasing activity was muted, Prest said. New Mexico budget forecasters never tallied the additional income.

New Mexico's nest-egg strategy

A nearly five-fold surge in local oil production since 2017 on federal and state land in New Mexico delivered a financial windfall for state government, helping fund higher teacher salaries, tuition-free college, universal free school meals and more.

The state set aside billions of dollars in investment trusts for future spending in case the world’s thirst for oil falters, including a early childhood education fund to help expand preschool, child care subsidies and home wellness visits for pregnancies and infants.

The state's investment nest egg has grown to $64 billion, second only to Alaska's Permanent Fund. Earnings from the trusts are New Mexico's second-biggest source for general fund spending.

That sturdy financial footing shaped a defiant response to this year’s federal government shutdown, when lawmakers voted to subsidize the state’s Affordable Care Act exchange, cover food assistance and backfill cuts to public broadcasting.

But lawmakers reviewing state finances learned that predictable income fell 1.6% — the first contraction since the start of the COVID-19 pandemic.

Muñoz said matters would be worse if the state had not raised its own royalty rates this year to 25%, from 20%, for new leases on prime oil and gas tracts, while ending a sales moratorium, under legislation he co-sponsored this year.

Encouraged in Alaska

After New Mexico, the states receiving the most federal oil and gas royalties are Wyoming, Louisiana, North Dakota and Texas.

Texas, the nation’s top oil producer, shares the bountiful Permian Basin with New Mexico but has far less federal land and therefore less exposure to changes in royalty policy.

In Alaska, state officials say they are encouraged by the royalty cut, seeing potential for increased development in places like the National Petroleum Reserve-Alaska, where the massive Willow project — approved in 2023 and now under development — is viewed by some as a catalyst for further activity. The reserve is expected to hold its first lease sales since 2019.

“If reduced federal royalty rates stimulate new leasing, exploration and production, that also could increase other kinds of revenue,” said Lorraine Henry, a spokesperson for Alaska’s Department of Natural Resources.

In North Dakota, federal royalties are split evenly between the state and county governments where drilling occurs. State Office of Management and Budget Director Joe Morrissette said the industry’s future remains difficult to forecast.

“There are so many variables, including timing, price, availability of desirable tracts, and federal policies regarding exploration activities,” Morrissette said.
