Just what does 'energy transition' mean, anyway? Photo via Shutterstock

The term “energy transition” is fraught with misconceptions, but not just because of the varied interpretation of the term “transition.” The Energy101 series on EnergyCapitalHTX.com brings clarity to both terms with simple and direct information that anyone can understand. As explored in a previous conversation with ChatGPT, we are all part of the Energy Industry, so its high time we all understood it.

DEFINING TERMINOLOGY

Merriam-Webster defines transition as “a change or shift from one state, subject, place, etc. to another.” The popular interpretation of ‘energy transition’ implies a complete shift away from energy produced from fossil fuels to energy produced from renewable sources. This isn’t entirely accurate–let’s explore why.

“The challenge of our lifetime is addressing [the] dual challenge of meeting increased global energy demand while confronting global climate change” says Jane Stricker, executive director of the Houston Energy Transition Initiative and senior vice president, Greater Houston Partnership. This globally inclusive definition of ‘energy transition’ focuses on addressing objectives instead of proffering solutions–a common project management viewpoint through which opportunities are explored.

It's a simple, but effective, way to expand one’s line of thinking from acute problem solving to broader root-cause analysis. In other words, it is how we elevate from playing checkers to mastering chess.

DEFINING THE OPPORTUNITY

The United Nations tells us the world’s population reached 8 billion in late 2022, an increase of more than one billion people in just over a decade. During the same time frame, the number of people around the world without consistent access to electricity declined from approximately 1.2 billion to 775 million per the International Energy Agency (IEA) 2022 World Energy Outlook report. A commendable feat, no doubt, but the fact remains that about 10% of the world’s population still lives in energy poverty–and that number is increasing.

The first half of Stricker’s sentiment, the challenge of “meeting increased global energy demand” reflects these statistics, albeit almost poetically. To state the issue more plainly, one could ask, “how do we get more energy to more people?” Taking it one step further, we can split that inquiry into two basic questions: (1) how to get more energy, and (2) how to reach more people. This is where it gets interesting.

As explored in the inaugural Energy 101 article, energy is converted into usable form through one of three reactions. Mechanical and nuclear reactions that create electricity for immediate consumption are often deemed “cleaner” than those produced by chemical reaction, but the challenges of delivering more energy consistently and reaching more people are left shortchanged due to intermittent production and limited distribution mechanisms.

In recent history, this has left us to rely upon energy produced by chemical reactions from fossil fuels and/or batteries. Batteries have inherently been the more expensive option, mostly because of the limited supply of minerals necessary to effectively store and transport energy for later use in these contained systems. Hence, the heavy reliance on cheap fossil fuels.

REFINED CONSTRAINTS DEMAND NEW SOLUTIONS

With price as the determining factor influencing the modern world’s energy supply, oil and natural gas have scrambled to compete with coal, which is affordable and easily transportable. However, coal has one major drawback–using it accounts for approximately 20% of carbon emissions, more than oil and gas industrial use, combined, per calculations from the U.S. Energy Information Agency.

We have a duty to get more energy to more people, “while confronting global climate change,” as Stricker states. In the context of energy poverty, where more consistent access to more electricity needs to reach more people, energy needs not only be abundant, reliable, affordable, and accessible, but also, less toxic.

So far, we have yet to find a solution that meets all these conditions, so we have made trade-offs. The ‘energy transition’ merely reflects the energy industry’s latest acceptance of the next hurdle to enhance our lives on earth. As depicted by the image from the IEA below, it most certainly reflects a reduction in the reliance on coal for electricity production, but how that energy reduction will be off set remains yet to be determined.

It's an opportunity ripe for exploration while existing sources push to meet the expanding definition of sustainable energy–a shift in evaluation criteria, some might say. Perhaps even a transition.

Hertha Metals raises $133M Series A round, plans high-purity iron plant

cleaner steel

Conroe-based Hertha Metals has closed a $133.65 million Series A round that includes a $65 million equity investment from the Pentagon. The startup uses a one-step process to convert iron into molten steel or high-purity iron.

Khosla Ventures and Doerr Capital co-led the round, with participation from CEV, Pear Ventures, Gates Frontier, Niterra SUISO no MORI Fund, Toyota Ventures, and Siemens Financial Services.

The federal investment came from the U.S. Department of Defense’s Industrial Base Analysis and Sustainment program. The program aims to strengthen and modernize the U.S. Defense Industrial Base, a network that researches, designs, builds, and maintains military weapons, equipment, technology, and services.

The Series A funding will finance construction of Hertha Chalyx, a plant that will be capable of producing 10,000 metric tons of steel-grade and magnet-grade high-purity iron.

Hertha says Chalyx will provide U.S.-made material for manufacturers of rare-earth magnets. Today, China controls more than 90 percent of the global manufacturing of rare-earth magnets.

Rare-earth magnets can be found in fighter jets, smart bombs, submarines, satellites, drones and other military hardware. These magnets are also key components in electric vehicle motors, wind turbines, computer hard drives, smartphones, headphones, cordless tools and an array of other products.

“Every electric vehicle, aerospace platform, radar system, and data center depends on domestic iron and magnet feedstock suppliers,” Laureen Meroueh, founder and CEO of Hertha, said in a press release.

“Hertha Chalyx closes that gap,” she added. “We are building the supply chain this country needs, and we are doing it by providing a domestic cost-competitive option for manufacturers while unlocking safer and cleaner production.”

Hertha says Chalyx, alongside its Pi100 pilot project, will be the first modern-day “iron and steel innovation complex.” The startup expects to break ground on Chalyx this year.

Since its founding in 2022, Hertha has raised more than $150 million from investors.

This spring, Hertha led the manufacturing category on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Houston carbon removal company secures $35M in financing

national scale

Houston-based Vaulted Deep, a waste management and carbon removal company, has announced a major $35 million debt facility from Italian investment bank Mediobanca to support its national expansion.

U.K.-based market energy solutions CFP Energy arranged the deal, which is “the largest publicly disclosed U.S. commercial debt deal in durable carbon removal to be secured by long-term purchase contracts,” according to a news release from the companies.

The financing will support new waste disposal sites for Vaulted Deep and advancements of the company’s AI-enabled site development platform. The platform helps identify locations, navigate permitting and optimize injection operations. When candidates are looking for sites, the platform will pull from regulatory, geology and waste-supply data to assist, which Vaulted Deep says will help streamline the permitting process. After the site is operating, the platform helps control algorithms to maximize safe disposal capacity and monitor the process along the way.

"Waste operators across the country need new options as traditional disposal options become limited,” Julia Reichelstein, CEO and co-founder of Vaulted Deep, said in the release. “This financing lets us take on more projects and invest in the tools that help us evaluate and develop new sites faster. This is a meaningful milestone for Vaulted as we move into the next phase of building infrastructure at a much larger scale."

The deal is supported by Vaulted Deep's long-term waste service and carbon removal purchase contracts. The company says it delivered more than 20,000 tons of carbon removal to buyers in the first half of 2026, which is more than it delivered in all of 2025.

"By facilitating these types of transactions, we connect institutional capital with innovative climate technologies, helping accelerate the deployment of high-integrity carbon removal solutions,” Tyler Manchester, head of voluntary carbon for CFP Energy, added in the release. “It reflects growing investor confidence in these solutions, driven by rising demand from corporate buyers seeking permanent pathways to support net-zero commitments and long-term climate strategies."

Beyond the facility, Vaulted Deep has secured $48 million in equity financing in addition to its $8 million from the XPRIZE Carbon Removal competition, backed by Elon Musk’s charitable organization, The Musk Foundation.

The company's well injection technology is used to store organic waste deep underground in stable geologic formations. In 2025, it inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.
