Houston-based Element Fuels has completed the pre-construction phase of its hydrogen-powered clean fuels refinery and combined-cycle power plant in the Port of Brownsville.

Element Fuels, which has contracted with Houston-based McDermott to provide front-end engineering design services for the project, has designed the plant to produce and recycle hydrogen that will generate and deliver cleaner, higher-quality fuels, including much-needed high-octane gasoline and electricity for commercial and consumer consumption.

“Element Fuels has received the necessary permitting to construct and operate a refinery capable of producing in excess of 160,000 barrels, or approximately 6.7 million gallons, per day of finished gasoline, diesel, and jet fuel,” Founder and Co-CEO of Element Fuels John Calce says in a news release. “A permit for a greenfield refinery of this size, scope, and functionality has not been granted in the United States since the 1970s. This speaks to the innovative approaches we are taking to address climate and sustainability concerns in cleaner, greener ways that are new to the refinery space.”

The project is expected to go online in 2027 and will produce enough low-carbon hydrogen to supply approximately 100 percent of the refinery’s fuel requirements, essentially eliminating CO2 emissions, per the news release. More than 100 megawatts of excess electricity generated from the power plant will be provided to the Energy Reliability Council of Texas for the surrounding community’s needs.

“Element Fuels is not only ushering in the next generation of clean fuels, we’re also proving that, without a doubt, there is a way to produce higher quality, cleaner, higher-octane fuels that significantly advance the energy transition," Calce continues. "This changes everything – for the industry, for consumers, and for the well-being of the planet.”

The plant is located in South Texas and built on more than 240 acres within the Port of Brownsville. Element Fuels is reportedly collaborating with local and Port officials "to advance the Justice40 initiative established by the U.S. Department of Commerce to contribute to a climate-positive environment that provides residents of the Brownsville area and Rio Grande Valley with clean energy and affordable and sustainable housing," per the release.

“Building on our successful collaboration during early project phases, we believe we are uniquely positioned to leverage our expertise and knowledge to further support Element Fuels throughout the next stages of this unique project,” adds Rob Shaul, senior vice president at Low Carbon Solutions at McDermott. “We remain focused on the delivery of low carbon pathway projects and are committed to advancing the landscape of energy production.”

Major oil exporters agree to keep production steady in November 2026

Oil News

Seven major oil-exporting countries agreed Sunday to keep production steady in November at a time when the Iran war has driven the price of benchmark Brent crude oil above $100 a barrel.

The so-called OPEC+ subgroup — Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria and Oman — will meet again on November 1 to review conditions in the oil market.

The fighting with Iran, which began with U.S. and Israeli attacks on Feb. 28, has disrupted global oil supplies and driven prices higher.

The group of seven wealthy democracies said Friday that they plan to release 100 million barrels of oil and fuel products in the coming weeks, starting with “substantial” amounts of diesel.

Diesel prices recently hit record highs in the United States, squeezing farmers, truckers and consumers who depend on the fuel.

The G7 promised a “frontloaded substantial release” of diesel within the next 20 days and the rest over four months.

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.
