“We are excited to have Halliburton's support as we scale-up our technology and deliver innovative minerals processing solutions that disrupt industry best practices, enhance global resource utilization, and benefit the environment and the communities we serve," Greyson Buckingham, Disa's CEO and president, says.

Marel Power Solutions, headquartered from Michigan, is innovating electrification through its novel powerstack technology. These materials-efficient, quickly deployable, and scalable power-stacks, encapsulating advanced cooling technology, redefine power conversion in mobility, industrial, and renewables spaces.

“We're thrilled to contribute to global climate sustainability. Our collaboration with Halliburton will accelerate the electrification transition across industries. Marel's technology not only maximizes heat evacuation from densely packed power semiconductors but, more importantly, offers substantial savings in cost, weight, size, and time, making it transformative in the evolving landscape of electrification,” Marel CEO Amrit Vivekanand says.

And lastly, XtraLit is an Israeli company that develops a technology for direct lithium extraction from brines. The technology enables efficient and economically justified processing of brines even with relatively low lithium concentrations. Application of the extraction technology will allow mineral providers to unlock new significant sources of lithium that are critical to meet growing demand.

“Oil and gas industry produced waters might become a substantial resource for lithium production,” says XtraLit CEO, Simon Litsyn. “XtraLit will cooperate with Halliburton on optimization of produced water treatment for further increasing the efficiency of the lithium extraction process.”

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.
