A Houston organization has announced a major energy efficiency and sustainability project that, in 20 years, will end up paying for itself with the savings alone.

The project is a collaboration between Wisconsin-based Johnson Controls (NYSE: JCI), Harris County Sports & Convention Corporation (HCSCC), NRG Park, and Harris County. The 20-year savings of the improvements are estimated to generate more than $54 million.

"We remain committed to maintaining NRG Park's distinct position as a part of the fabric of our community and a landmark for visitors globally," Ryan Walsh, CEO and executive director of HCSCC and NRG Park, says in a news release. "These enhancements allow us to maintain our reputation for excellence and continue to deliver the best fan experiences, while exploring innovative and financially responsible approaches to sustainability."

The project, according to the news release, is expected to reduce carbon dioxide emissions by over 241,000 metric tons a year. The plan includes: upgrades to HVAC equipment, building automation systems, water conservation, life safety systems and lighting improvements, and the high-efficiency chiller system.

Additionally, the park will integrate a system from Johnson Controls — OpenBlue Central Utility Plant — and the company will continue to measure and track results through an ongoing service agreement.

"Our partnership with Harris County and HCSCC's team to guide the enhancement initiative at NRG Park is paving the way for more sustainable practices across the sports and entertainment sector," Julie Brandt, president of Building Solutions North America at Johnson Controls, says in a statement. "We look forward to seeing how this project will inspire other industry leaders and drive smart savings and significant emissions reduction, not only in Harris County but on a national scale."

NRG Park, comprised of NRG Center, NRG Stadium and NRG Arena, is home to the annual 20-day Houston Livestock Show and Rodeo and the NFL Houston Texans. The 350-acre complex will also host the College Football Playoff Championship, the FIFA World Cup, and more than 500 other events this year.

"NRG Park is a premier destination that welcomes more than 5.5 million people annually," says Rodney Ellis, Harris County Commissioner for Precinct 1, in the release. "These enhancements will create a more enjoyable and resilient environment for people traveling from near and far to attend the multitude of events hosted there."

It's not the first time NRG has invested in energy efficiency. In 2014, NRG Stadium became the first professional football stadium in the country with LED lights, Elizabeth Killinger, executive vice president of NRG Retail, said at the time. NRG also became the first professional sports stadium in Texas to install solar panels. At the time, the organization also announced electric vehicle charging stations.

Earlier this year, the Houston Texans announced a sustainability project of their own. In partnership with 1PointFive, the Texans’ Preferred Carbon Removal Partner, the team launched the Touchdown for Trees program the Touchdown for Trees program to recapture carbon emissions. For every touchdown scored by the Texans in the 2022, 2023, and 2024 seasons, the team pledges to plant 1.5 trees in the greater Houston area.

Hertha Metals breaks ground on $100M high-purity iron factory in Conroe

coming soon

Shortly after announcing a $133.65 Series A funding round, Conroe-based Hertha Metals broke ground Oct. 8 on a $100 million factory that will produce steel-grade and magnet-grade high-purity iron.

Hertha’s Chalyx plant, located in Conroe, will manufacture a total of about 10,000 metric tons per year of magnet-grade and steel-grade high-purity iron. The factory will use Hertha’s single-step process to generate high-purity iron for rare-earth-magnet and steel manufacturers in the U.S.

Hertha says Chalyx will be the first U.S. commercial plant for production of magnet-grade high-purity iron.

Chalyx is being built next to Hertha’s headquarters and its Pi100 pilot plant, which will remain in operation. Chalyx and Pi100 will form the first modern-day iron and steel “innovation complex” in the U.S., the company says.

“I founded Hertha Metals because I believed we could significantly improve how the world makes iron and steel from ore, and that an industry so fundamental to our future still had enormous room for invention,” Laureen Meroueh, founder and CEO of Hertha, said in a press release.

The 4-year-old startup says the Chalyx complex will lay the foundation for its first 500,000-ton-per-year steel mill.

Chalyx’s first priority is making high-purity iron for U.S. manufacturers of rare-earth magnets, Hertha says. These magnets are critical components for electric vehicles, data centers, wind turbines and defense systems.

China produces an estimated 94 percent of high-purity iron for rare-earth magnets, according to Hertha.

Aside from iron for rare-earth magnets, Chalyx will make iron and steel for pilot projects in the steel industry.

The plant is expected to come online in late 2027, with production of magnet-grade high-purity iron starting in early 2028.

Today, Hertha employs 32 people, the company says. Once it’s fully operating, the Chalyx plant will employ about 50 people.

Just ahead of the groundbreaking, Hertha announced the $133.65 million Series A round, co-led by Khosla Ventures and Doerr Capital. The round included a $65 million equity investment from the Pentagon.

“Iron and steel have shaped human progress for thousands of years. And I believe there is still an enormous amount left to invent,” Meroueh said at the groundbreaking ceremony.

Canada-founded energy tech company moves global HQ to Energy Corridor

houston hq

Pulsed-power technology company BlueSpark Energy will open its new global headquarters in Houston’s Energy Corridor to house its engineering, research and development, manufacturing, commercial and digital teams.

“Houston isn’t simply our new headquarters; it’s where a new BlueSpark begins,” Kahina Abdeli-Galinier, president and CEO of BlueSpark, said in a news release. ”We’re building the well health technology the industry needs to get more from existing wells, reduce intervention costs and keep wells producing for longer. Our new home brings us closer to our customers and places us at the heart of one of the most exciting markets in the industry, with the talent pool to match.”

The company, which began in Calgary, plans to grow its Houston workforce to 100 employees by the end of 2028, while the manufacturing element is expected to be operational in February 2027.

According to BlueSpark, the new facility will feature double the manufacturing floorspace of its current site, and the extra space will allow it to scale its tool manufacturing.

The headquarters is on West Sam Houston Parkway. BlueSpark's Chief Technology Officer Matt Mohajer and Chief Commercial Officer Zach Wilbur are already leading teams at the new space, according to the release.

BlueSpark develops pulsed-power technology that uses electrical energy to clean oil and gas well components, remove scale buildup and restore production without damaging equipment. Its technology helps operators reduce downtime, improve well performance and extend the productive life of existing wells.

Late last year, the company named Kahina Abdeli-Galinier as its CEO. It has since rebranded and focused on expanding its technology into new applications, including plugging and abandonment, cement removal and water services.

“We’re investing heavily in our technology, both the physics and the intelligence and delivery layer around it,” Abdeli-Galinier added in the release. “Having our engineering, manufacturing, digital, R&D and commercial teams in one place allows us to move much faster, giving our customers the tools they need to keep wells healthy and producing more for longer.”
