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.”

Houston-area company to develop next-gen batteries for electric helicopters

emissions-free flight

Webster-based KULR Technology Group has announced a strategic co-development collaboration with Robinson Helicopter Company (RHC) to develop a next-generation, high-performance battery system for the eR66 battery-electric helicopter demonstrator.

KULR, an electronics manufacturing company, will serve as the developer of the advanced battery system for the eR66 platform. KULR will design and integrate a high-performance battery structure that uses its proprietary battery safety technologies and thermal management solutions, previously developed for aerospace and spaceflight applications.

California-based Robinson Helicopter Company is the world's leading manufacturer of civil helicopters. Its eR66 is expected to deliver zero-emission, affordable and quiet performance for “high-demand applications.”

“Robinson Helicopter has built more civil helicopters than any manufacturer on Earth, and their commitment to reliability is exactly the standard KULR’s battery architecture is designed to meet,” Michael Mo, CEO of KULR, said in a news release. “KULR’s battery systems have been qualified for NASA spaceflight. They were designed from day one for dual use: a primary flight cycle and a certified second life. The eR66 is where that architecture proves itself in rotorcraft.”

David Smith, president and CEO of Robinson Helicopter Company, cited the partnership as a shift in service for commercial and civil operations and touted the potential environmental benefits.

“By integrating electric propulsion, we aren't just reducing our environmental impact; we are unlocking critical new capabilities for life-saving missions,” Smith added in the release. “For use cases like rapid organ and tissue transport, the reduced acoustic signature and zero-emission profile ensure that time-sensitive, low-emission deliveries are faster, quieter, and more sustainable than ever before."

The companies say, through the partnership, they aim to:

  • Advance eR66 performance
  • Enhance aviation safety
  • Increase cost efficiency
  • Uphold American aerospace leadership
  • Support decarbonization
  • Promote circular economy principles

Tesla's EV Robotaxis officially launch in Texas' largest metros

On The Road

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Major Texas energy port wrestles with water crisis due to years of drought

Resource Report

In parched southern Texas, a yearslong drought has depleted Corpus Christi's water reserves so gravely that the city is scrambling to prevent a shortage that could force painful cutbacks for residents and hobble the refineries and petrochemical plants in a major energy port.

Experts said the city didn't expect such a bad drought, and new sources of reliable water didn't arrive as expected. Those problems arose as the city increased its water sales to big industrial customers.

“We just have not kept up with water supply and water infrastructure like we should have. And it's decades in the making,” said Peter Zanoni, the city manager since 2019.

Corpus Christi, a city of about 317,000 people that also supplies water to nearby counties, is closely tied to its oil and gas industry. The region makes everyday essentials like fuel and steel and ships them to the world.

Zanoni said it is highly unlikely the city will run out of water, but without significant rainfall or new sources, residents may face forced cutbacks and industry may have to do with less. At a time when the Iran war is already raising gas prices, the shortage is hitting an area that produces 5% of the U.S. gasoline supply.

Droughts are common, but this one has dragged on for most of the past seven years. Key reservoirs are at their lowest point ever. The quickest fix is different weather.

“We are actively praying for a hurricane,” former city council member David Loeb said, half in jest. Loeb doesn't want anyone injured, but after wrestling with previous droughts in his time on the council, he feels the lack of rain acutely.

The drought isn't expected to lift by summer, leaving officials scrambling to tap more groundwater to avoid an emergency.

Lessons from last time

After the last drought in the early 2010s, the city approved a pipeline extension to bring in more water from the Colorado River and promoted conservation. In the years that followed, water use actually fell. The city, seeing opportunity, added a petrochemical plant and steel mill to its long list of industrial customers.

City officials had allowed for drought in their calculations — just not this kind of drought, Zanoni said. It has hit especially hard because reservoirs never fully recharged after the last one.

And it's come at a bad time.

After many years, the pipeline extension finally delivered its full capacity only last year. Meanwhile, discussion of building a desalination plant that would remove salt from seawater — a potentially drought-proof solution recommended in 2016 — bogged down over concerns about costs as high as $1.3 billion and environmental impact.

“If the then-city council had followed through on that, we would have had that plant up and running by now,” Zanoni said.

It's an industry town

Corpus Christi has followed its long-established plan for reducing water use. Stage 1 seeks voluntary actions from citizens like taking shorter showers and limiting how often they can water. Currently, the city is in Stage 3, which means pauses on many outdoor water uses.

Many residents are angry that they can’t water their lawns, that their bills are set to rise sharply and that they may face fines, said Isabel Araiza, co-founder of a grassroots group active on water issues. Some don’t feel industry will be asked to share in the pain, she said.

The city's drought plan allows for charging residents and businesses extra if they use lots of water. But big industry, which Zanoni says consumes as much as 60% of the city's water, can opt to pay a permanent surcharge to avoid the possibility of having a much larger fee added in times of drought.

Araiza calls it a bad system. Once industry pays the surcharge, she said, they have no incentive to conserve water.

The city has defended the system, saying in a statement that industry does not “get a pass on water conservation” or forced curtailment. The statement said the business surcharges have raised $6 million a year.

It is wrong to suggest industry isn’t helping, said Bob Paulison, executive director of the Coastal Bend Industry Association. Companies have stopped landscaping, they recycle water for essential cooling needs and they are looking for alternative water sources, he said.

The city hasn't imposed extra costs on anyone yet.

But Zanoni said water rates may eventually double as the city invests roughly $1 billion on infrastructure — costs that some argue will disproportionately benefit industry and make life for residents more expensive.

What's the way out?

The city is in a water emergency when it has 180 days before water supply can't keep up with demand. Officials have run through different scenarios for getting new water and the drought easing, and have said an emergency could come as early as May, as late as October, or not at all.

The city has tapped into millions of gallons of new groundwater, and it hopes to get even more.

The biggest unknown is the Evangeline Groundwater Project, which involves a pipeline and about two dozen wells that could add enough water to head off an emergency. It still needs state approval but the city hopes water could be flowing as soon as November. New sources come with drawbacks – some have raised water quality concerns, and there are worries too much pumping could deplete groundwater.

If the city has to declare a water emergency, it would be able to more aggressively curtail water use – mandatory reductions that would apply evenly to all industry and residents. That is a sensitive decision and is likely to be a “knock-down drag-out bloodbath,” Loeb said.

Because residents on average have already reduced their water use, future mandatory cuts are likely to fall heavier on industry.

“It’ll be an unbelievable disaster,” said Don Roach, former assistant general manager of the San Patricio Municipal Water District that has lots of industrial customers in the area. “When you cut the cooling water off to most of these industries, they just have to shut down. There’s no other way around it.”

Paulison said companies that produce fuel, polymers, iron and steel “have the least amount of flexibility in just cutting water usage.” He added, however, that companies remain optimistic they can reduce usage, adapt and continue operations.

Zanoni said the city's plans should buy time to avert the worst.

“We are hoping we don’t get there, but we don’t work on hope,” he said.
