Another energy company in Houston is going public amid a flurry of energy IPOs.

Houston-based ERock Inc., which specializes in utility-grade onsite microgrid systems for data centers and other customers, has filed paperwork with the U.S. Securities and Exchange Commission (SEC) to sell its shares on the New York Stock Exchange.

The ERock filing follows the recent $1.9 billion IPO of Houston-based Fervo Energy, a provider of geothermal power that’s now valued at $7.7 billion.

Another Houston energy company, EagleRock Land, just went public in a $320 million IPO that values the company at $3 billion. EagleRock owns or controls about 236,000 acres in the Permian Basin, earning money from royalties, fees, easements, water services and other revenue streams tied to drilling on its land.

According to Barron’s, more than a dozen energy and energy-related companies in the U.S. have gone public since the beginning of 2025, with the bulk of the IPOs happening this year.

ERock’s SEC filing doesn’t identify the per-share pricing range for the IPO or the number of Class A shares to be offered. ERock is a portfolio company of Energy Impact Partners, a New York City-based venture capital and private equity firm that invests in energy companies.

The company previously did business as Enchanted Rock. ERock Inc., formed in January, will function as a holding company that controls predecessor company ER Holdings Ltd.

In 2025, ERock generated revenue of $183.1 million, up 42.5 percent from the previous year, according to the IPO filing. It recorded a net loss of $59 million last year.

As of March 31, ERock boasted a sales backlog of nearly $1.3 billion, up 779 percent on a year-over-year basis. The company attributes most of that increase to greater demand from data centers.

The company primarily serves the power needs of data centers, utilities, industrial facilities, and commercial buildings. Its biggest markets are Texas and California.

“Several U.S. markets, such as Texas and California, face especially acute reliability risks,” ERock says in the SEC filing. “Texas already shows rapid load-growth pressures tied to data centers and industrial expansion, while California faces grid congestion, long interconnection queues, and above-average vulnerability to extreme heat- and weather-driven outages.”

Since its founding in 2018, ERock has installed microgrid systems at more than 400 sites with a capacity of about 1,000 megawatts. Customers include ComEd, Foxconn, H-E-B, Microsoft and Walmart.

By the end of this year, the company plans to expand its production of microgrid systems to a capacity of about 1.2 gigawatts with the opening of its Hyperion facility in Houston.

John Carrington leads ERock as CEO. He joined ER Holdings last year as chairman and CEO. Carrington previously was CEO of Houston-based Stem, a public company that offers AI-enabled clean energy software and services. Earlier, he spent 16 years at General Electric.

New collaboration to build data center microgrid in Houston

coming soon

Two companies are teaming up to build a natural gas microgrid in Houston that will reduce emissions by 98 percent.

Provider of prime and backup power solutions RPower has teamed up with Houston’s ViVaVerse Solutions to build a 17-megawatt (MW) microgrid at the ViVa Center campus in Houston, which is expected to be commissioned by the end of the year.

The microgrid plans to employ ultra-low emissions and natural gas generators to deliver Resiliency-as-a-Service (RaaS), and this will connect to ViVaVerse's colocation data center operations during utility outages.

RPower will also deploy the microgrid across different ERCOT market programs, which will contribute to assist with essential capacity and ancillary services for the local grid. ERCOT has increased its use of renewable energy in recent years, but still has faced criticism for unstable conditions. The microgrids can potentially assist ERCOT, and also help cut back on emissions.

“RPower's pioneering microgrid will not only deliver essential N+1 resiliency to our data center operations but will also contribute to the local community by supplying necessary capacity during peak demand periods when the electric grid is strained,” Eduardo Morales, CEO of ViVaVerse Solutions and Morales Capital Group, says in a news release.

ViVaVerse Solutions will be converting the former Compaq Computer/HPE headquarters Campus into an innovative technology hub called the ViVa Center, which will host the High-Performance Computing Data Center, and spaces dedicated to mission critical infrastructure and technical facilities . The hub will host 200 data labs.

“We are thrilled to partner with ViVaVerse to deploy this `first of its kind' microgrid solution in the data center space,” Jeff Starcher, CEO of RPower, adds. “Our natural gas backup generation system delivers the same reliability and performance as traditional diesel systems, but with a 98 percent reduction in emissions. Further, the RPower system provides critical grid services and will respond to the volatility of renewable generation, further enabling the energy transition to a carbon free future.”

Houston mobile hydrogen generator company gets PE backing to expand its business

fueling the future

An innovative Houston-area company is on a mission to make using hydrogen energy easier and cheaper.

A recently announced partnership with investment firm, Balcor Companies, will help make this a reality as Kaizen Clean Energy looks to make hydrogen energy more accessible, reliable and affordable. Announced July 6, Balcor now has an ownership stake in Kaizen. The terms of the deal were not disclosed.

The company, based in Tomball, has developed a “micro grid” hydrogen power station — a mobile, scalable energy source that can be used anywhere, anytime.

Balcor Companies Founder and Director Chris Balat says his company is looking at their stake in KCE as an investment in shaping a more sustainable world.

“We are thrilled to make our first foray into the energy sector with Kaizen Energy as our trusted partner,” he says in a statement. "Our association with Kaizen is a testament to our commitment towards a sustainable future, driving positive change in the world while delivering value to our stakeholders.”

Kaizen's mission is to succeed where electric grids fail. One fallback source to help strained electric grids has typically been diesel generators. However, diesel generators increase local emissions which produce a significant amount of air pollution and health concerns. Kaizen’s hydrogen generators can be used to power buildings, homes, hospitals, data centers, events, and farm equipment. They are portable, which means it does not require any excessive infrastructure.

“Our system allows customers the ability to have renewable energy anywhere in the world in a very short time frame,” said Eric Smith, co-founder of KCE. “For EV charging, for power generation, to replace a diesel generator.”

Smith tells EnergyCapitalhtx the concept is very attractive to corporations who lease buildings as building out a permanent infrastructure could be costly and time consuming.

Robert Meaney, a Texas Tech engineering graduate, founded Kaizen Clean Energy in 2020, along with Eric Smith and Craig Klaasmeyer. Meaney designed the technology using a mixture of methanol and water to create hydrogen. A 330-gallon tank of the mixture produces about 150 kilograms of hydrogen — or 1.6 megawatt-hours of energy. The mixture lowers the risks of many of the drawbacks of hydrogen usage. For example, it can be stored for longer periods and transported long distances safely.

The microgrid fits into a small container and can be dropped on site at remote locations or in heavily congested grid areas. It also eliminates the cost of hydrogen transportation by generating hydrogen on-site with commonly available methanol, which can be both used for hydrogen fuel and converted to electricity for electric vehicle charging. This microgrid technology can both connect to the grid to supplement available power, or can be used during a power outage.

To put this energy source to use, KCE has partnered with Extreme E, an international off-road racing series that is part of Formula 1 and uses electric SUV’s to race in remote parts of the world. Kaizen’s units are also being used at a fleet-charging location in Los Angeles.

How Mitsubishi Heavy Industries America is advancing the hydrogen economy

The View from HETI

Mitsubishi Heavy Industries America (MHIA), a steering-level member company of the Houston Energy Transition Initiative, is leveraging engineering expertise and global capabilities to develop and deploy technologies that will decarbonize existing infrastructure and build the hydrogen economy of the future. The company’s recent investment in Koloma, a Colorado-based geologic hydrogen exploration startup, demonstrates its commitment to breakthrough innovations that can transform how the world produces and uses clean energy.

Traditional hydrogen production methods, whether from natural gas with carbon capture or from electrolysis using renewable electricity, require significant energy inputs and infrastructure investments. Geologic hydrogen represents a potentially transformative alternative: naturally occurring hydrogen deposits that can be extracted from underground reservoirs.

Koloma is pioneering the exploration and commercialization of geologic hydrogen using proprietary technology, unique data sets, and specialized expertise to identify and develop these resources globally. If successful at scale, geologic hydrogen could provide clean, affordable hydrogen without the energy penalty of production.

MHIA’s investment in Koloma joins a syndicate of strategic partners committed to accelerating hydrogen development:

Breakthrough Energy Ventures: Bill Gates’ climate investment fund focused on breakthrough technologies

Amazon’s Climate Pledge Fund: Supporting technologies that enable Amazon’s path to net zero

United Airlines’ Sustainable Flight Fund: Investing in solutions for aviation decarbonization

This partnership brings together technology innovation, capital, and potential customers to create the ecosystem needed to move from exploration to commercial deployment.

MHIA’s investment in geologic hydrogen is part of the company’s broader strategy to develop the complete hydrogen value chain:

Production: Beyond geologic hydrogen, MHIA is advancing technologies for hydrogen production from diverse sources, including natural gas with carbon capture and renewable-powered electrolysis.

Infrastructure: The company is developing the compression, storage, and transportation systems needed to move hydrogen from production sites to end users.

End-Use Applications: MHIA’s expertise spans power generation, industrial processes, and transportation applications that can utilize hydrogen as a clean fuel.

Integration: The company is working to integrate hydrogen systems with existing infrastructure, enabling decarbonization without requiring complete infrastructure replacement.

While new technologies like geologic hydrogen offer exciting possibilities, MHIA recognizes that much of the world’s energy infrastructure will continue operating for decades. The company is also investing in technologies that decarbonize existing systems:

MHIA is developing and deploying carbon capture systems that can be retrofitted to existing power plants and industrial facilities, allowing them to continue operating while dramatically reducing emissions.

The company’s gas turbine technologies can operate on blends of natural gas and hydrogen, enabling progressive decarbonization as hydrogen availability increases.

Through advanced controls, materials, and designs, MHIA is improving the efficiency of existing infrastructure—reducing fuel consumption and emissions without requiring replacement.

MHIA’s approach to the energy transition is guided by a clear mission: develop innovative technologies that help achieve a decarbonized society while maintaining energy security and affordability. This mission recognizes several important realities:

Energy Access Matters: Billions of people still lack access to reliable, affordable energy. Solutions must scale globally and work across diverse economic contexts.

Existing Infrastructure Represents Enormous Investment: The world has trillions of dollars invested in energy infrastructure. Solutions that work with this infrastructure can deploy faster than those requiring complete replacement.

Multiple Pathways Are Needed: No single technology will solve the climate challenge. Success requires parallel development of multiple solutions—hydrogen, carbon capture, renewables, nuclear, efficiency, and others.

Speed Matters: Climate change is a time-sensitive challenge. Technologies that can deploy at scale in the 2020s and 2030s matter more than perfect solutions that might be available in the 2040s or 2050s.

From Technology to Impact

MHIA’s investment in Koloma reflects the company’s belief that breakthrough technologies require patient capital, technical expertise, and strategic partnerships to move from concept to commercial reality. Geologic hydrogen has the potential to provide clean, affordable hydrogen at scale—but only if exploration techniques are validated, production methods are proven, and commercial models are demonstrated.

By investing early and providing both capital and technical support, MHIA is helping to accelerate this timeline. If Koloma succeeds, the impact could extend far beyond a single project and could unlock a vast new resource for the global energy transition.

The energy transition requires engineering excellence, patient capital, and willingness to back breakthrough innovations before they’re fully proven. Through HETI member companies like Mitsubishi Heavy Industries America, Houston is demonstrating the leadership, technical capabilities, and strategic vision needed to build a hydrogen economy that can help decarbonize the world’s energy system.

Energy expert: Houston welcomed the world — can Texas power what's next?

guest column

For a few weeks this summer, Houston welcomed the world.

The FIFA World Cup 2026 showcased our city's ability to host one of the largest international events on the planet. Millions watched from around the globe while hundreds of thousands of visitors experienced firsthand what Houston has become: a world-class destination for business, culture and global events.

But once the final match is played and the visitors return home, a more important question remains: Can Texas build the energy infrastructure needed to power what comes next?

The World Cup wasn't the finish line. It was a glimpse into the future.

That future is being shaped not only by population growth, but also by artificial intelligence, hyperscale data centers, advanced manufacturing, electrification, LNG expansion and continued industrial investment. Together, these forces are creating an unprecedented demand for electricity and placing new expectations on the infrastructure that supports it.

Energy Has Become Economic Infrastructure

For decades, economic development centered around highways, ports, airports and workforce.

Today, another asset has moved to the top of that list: energy infrastructure.

Reliable electricity is no longer simply a utility service. It has become a competitive advantage.

Companies evaluating where to build the next AI campus, manufacturing facility or industrial complex are increasingly asking different questions. How quickly can power be delivered? Is there enough transmission capacity? Can substations support future expansion? Is water infrastructure available? What is the long-term reliability of the local grid?

These questions are becoming just as important as tax incentives and available real estate.

Recent comments from Governor Greg Abbott that future AI developments should provide their own power generation and water illustrate just how dramatically the conversation has evolved. The challenge is no longer limited to meeting today's demand. It is preparing for a future where entirely new industries require unprecedented amounts of electricity while ensuring existing homes and businesses continue to receive reliable, affordable service.

The Next Energy Race Has Already Begun

Texas remains the nation's energy leader, producing more electricity than any other state while continuing to expand natural gas, wind, solar and emerging technologies.

But leadership in the next decade will be measured differently.

Success will depend on how quickly we can expand transmission infrastructure, modernize distribution systems, accelerate interconnection, strengthen grid resilience and support new generation where economic growth is occurring.

The conversation has shifted from producing more electricity to delivering it smarter.

That requires planning years before demand arrives.

Houston Is the Proving Ground

Houston sits at the center of this transformation.

Already recognized as the Energy Capital of the World, the region continues attracting major employers, global headquarters, industrial expansion and technology investment. The Port of Houston continues to grow. Advanced manufacturing is expanding. AI companies are evaluating Texas alongside other national markets.

Every one of these investments depends on reliable infrastructure.

While the World Cup demonstrated Houston's ability to manage a temporary surge of visitors, the more significant challenge lies ahead. Permanent economic growth creates sustained electricity demand that cannot be addressed with temporary solutions.

Meeting that demand will require coordinated investment across generation, transmission, distribution, storage and increasingly, digital technologies capable of forecasting and managing electricity in real time.

Smarter Infrastructure for a Smarter Grid

The future electric grid will look very different from the one that built modern Texas.

Artificial intelligence, predictive analytics, advanced sensors and distributed energy resources will allow operators to anticipate demand, identify equipment failures before they occur and optimize energy delivery across increasingly complex networks.

Infrastructure is no longer simply about building more. It is about building smarter.

At the same time, resilience must remain central to every investment. Texans understand better than most that hurricanes, flooding, winter storms and prolonged heat waves are no longer rare events. Modern infrastructure must not only support growth but also withstand increasingly volatile weather.

Building Beyond the Headlines

The World Cup generated headlines because of what happened on the field.

Its lasting legacy may be what it revealed about the city beyond the stadium.

Houston demonstrated that it can host the world. The next challenge is ensuring it can continue to power one of the fastest-growing economies in North America.

That will require continued investment, thoughtful policy and long-term planning that recognizes energy infrastructure as essential economic infrastructure.

Texas has spent decades leading the world in energy production.

The next opportunity is even greater.

To become the global leader in how energy systems are planned, built and operated for a future defined by artificial intelligence, industrial growth and rapidly evolving consumer demand.

Because the cities that lead tomorrow won't simply generate the most energy.

They'll be the ones best prepared to deliver it where opportunity is growing.
