A Norway-based provider of technology for power grids whose U.S. headquarters is in Houston has raised a $25 million series B round of funding.

The venture capital arm of Polish energy giant Orlen, Norwegian cleantech fund NRP Zero, and the Norway-based Steinsvik Family Office co-led Heimdall Energy's round. Existing investors, including Investinor, Ebony, Hafslund, Lyse, and Sarsia Seed, chipped in $8.5 million of the $25 million round.

“This funding gives us fuel to grow internationally, as we continue to build our organization with the best people and industry experts in the world,” Jørgen Festervoll, CEO of Heimdall, says in a news release.

Founded in 2016, Heimdall supplies software and sensors for monitoring overhead power lines. The company says its technology can generate up to 40 percent in additional transmission capacity from existing power lines.

Heimdall entered the U.S. market in 2023 with the opening of its Houston office after operating for several years in the European market.

“Heimdall Power has built itself a unique position as an enabler for the ongoing energy transition, with fast-increasing electricity demand and queues of renewables waiting to get connected,” says Marek Garniewski, president of Orlen’s VC fund.

Heimdall says it will put the fresh funding toward scaling up production and installation of its “magic ball” sphere-shaped sensors. In the U.S., these sensors help operators of power grids maximize the capacity of the aging power infrastructure.

“In the United States alone, there are over 500,000 miles of power lines — most of which have a far higher transmission capacity than grid operators have historically been able to realize. To increase capacity, many have launched large-scale and expensive infrastructure projects,” Heimdall says.

Now, the U.S. government has stepped in to ensure that utilities are gaining more capacity from the existing infrastructure, aiming to upgrade 100,000 miles of transmission lines over the next five years.

Heimdall's technology enables grid operators and utilities to boost transmission capacity without undertaking lengthy, costly infrastructure projects. Earlier this year, the company kicked off the largest grid optimization project in the U.S. with Minnesota-based Great River Energy.

New report maps Houston workforce development strategies as companies transition to cleaner energy

to-do list

The University of Houston’s Energy University latest study with UH’s Division of Energy and Innovation with stakeholders from the energy industry, academia have released findings from a collaborative white paper, titled "Workforce Development for the Future of Energy.”

UH Energy’s workforce analysis found that the greatest workforce gains occur with an “all-of-the-above” strategy to address the global shift towards low-carbon energy solutions. This would balance electrification and increased attention to renewables with liquid fuels, biomass, hydrogen, carbon capture, utilization and storage commonly known as CCUS, and carbon dioxide removal, according to a news release.

The authors of the paper believe this would support economic and employment growth, which would leverage workers from traditional energy sectors that may lose jobs during the transition.

The emerging hydrogen ecosystem is expected to create about 180,000 new jobs in the greater Houston area, which will offer an average annual income of approximately $75,000. Currently, 40 percent of Houston’s employment is tied to the energy sector.

“To sustain the Houston region’s growth, it’s important that we broaden workforce participation and opportunities,” Ramanan Krishnamoorti, vice president of energy and innovation at UH, says in a news release. “Ensuring workforce readiness for new energy jobs and making sure we include disadvantaged communities is crucial.”

Some of the key takeaways include strategies that include partnering for success, hands-on training programs, flexible education pathways, comprehensive support services, and early and ongoing outreach initiatives.

“The greater Houston area’s journey towards a low-carbon future is both a challenge and an opportunity,” Krishnamoorti continues. “The region’s ability to adapt and lead in this new era will depend on its commitment to collaboration, innovation, and inclusivity. By preparing its workforce, engaging its communities, and leveraging its industrial heritage, we can redefine our region and continue to thrive as a global energy leader.”

The study was backed by federal funding from the Department of the Treasury through the State of Texas under the Resources and Ecosystems Sustainability, Tourist Opportunities, and Revived Economies of the Gulf Coast States Act of 2012.

Houston geothermal startup selects Texas location for first energy storage facility

major milestone

Houston-based geothermal energy startup Sage Geosystems has teamed up with a utility provider for an energy storage facility in the San Antonio metro area.

The three-megawatt EarthStore facility will be on land controlled by the San Miguel Electric Cooperative, which produces electricity for customers in 47 South Texas counties. The facility will be located in the town of Christine, near the cooperative’s coal-fired power plant.

Sage says its energy storage system will be paired with solar energy to supply power for the grid operated by the Electric Reliability Council of Texas (ERCOT). The facility is set to open later this year.

“Once operational, our EarthStore facility in Christine will be the first geothermal energy storage system to store potential energy deep in the earth and supply electrons to a power grid,” Cindy Taff, CEO of Sage Geosystems, says in a news release.

The facility is being designed to store geothermal energy during six- to 10-hour periods.

“Long-duration energy storage is crucial for the ERCOT utility grid, especially with the increasing integration of intermittent wind and solar power generation,” says Craig Courter, CEO of the San Miguel Electric Cooperative.
