HGP joins DOE nuclear AI project aimed at reactor load-following

HGP Intelligent Energy has joined Prometheus, a $230 million Department of Energy-led nuclear AI program that aims to speed reactor design, licensing and operations while helping power data centers without leaning on the public grid. The Dallas company will contribute its digital twin and variable-speed reactor coolant pump technologies as the program works toward lower costs and faster deployment.

Why it matters: - Prometheus is aimed at making nuclear power faster, safer and cheaper at a time when the U.S. needs an estimated 300 gigawatts of new nuclear capacity by 2050. - HGP's technology targets a major AI infrastructure problem: how to supply data centers with dedicated power without pushing more demand onto utility grids and ratepayers. - The program's goals include cutting design and licensing time by 10x, manufacturing time by 3x and operating staff by 50%.

What happened: - HGP Intelligent Energy said it was named a contributing commercial partner in Prometheus, the Idaho National Laboratory-led program selected by the U.S. Department of Energy under the Genesis Mission. - The announcement came July 22, 2026, and was made as Secretary of Energy Chris Wright introduced the program at the Genesis Mission Summit in Washington. - Idaho National Laboratory lists HGP among the Prometheus partners. - Prometheus is the largest of the DOE's 278 selected projects and the only Phase II award. - The program brings together four DOE national laboratories, four research universities and 25 commercial partners. - Commercial partners include Microsoft, Amazon Web Services, NVIDIA, Westinghouse, GE Vernova, TerraPower, Oklo, X-energy, Aalo Atomics and HGP.

The details: - Prometheus directs $60 million in federal funding over three years to the participating national laboratories and universities. - Commercial partners have committed more than $250 million in matching support. - HGP is participating in the AI for Nuclear Energy Consortium, the commercial coalition organized under the program. - HGP is working with Argonne National Laboratory to validate and verify its technology. - HGP's NTH-Sim digital twin provides real-time core monitoring and predictive safety analytics. - HGP says NTH-Sim has validated solvers across pressurized water, sodium fast and microreactor classes. - HGP's variable-frequency-drive reactor coolant pumps are designed for continuous variable-speed operation. - The pumps are intended to let proven reactor designs load-follow and track minute-to-minute demand without moving control rods. - Prometheus says reactor operations remain labor-intensive and manually driven, and the HGP technologies are meant to close that gap. - The program also aims to demonstrate at least seven continuous days of autonomous operation of a commercial microreactor at half the required staff. - HGP says its goal is to make dedicated on-site nuclear generation commercially practical for data centers under private contract. - HGP said the model would keep the cost of serving data centers from being socialized across utility ratepayers. - The company said it is not operating a facility under that model today. - HGP is headquartered in Dallas and says its technologies are being developed with Texas manufacturing partners. - HGP says its team includes three decades of power sector experience, including a First of a Kind battery energy storage resource approved by ERCOT in 2019 and in operation since. - HGP says it has pending patent applications covering variable-speed reactor coolant pumps, AI-powered digital twin systems and extended fuel life technology. - More information is available in the company's announcement.

Between the lines: - Prometheus reflects a broader push to tie AI and nuclear development together as utilities, data center operators and federal labs look for power sources that can scale faster than traditional nuclear timelines. - HGP is framing its technology as a commercialization bridge, not just a research tool, with a focus on reactor flexibility and operating efficiency. - The release also makes clear that HGP is a contributor to Prometheus, not a recipient of federal funding under it. - DOE funds support the national laboratories and universities, and no DOE funds flow to or through the AI for Nuclear Energy Consortium. - HGP's participation remains subject to definitive agreement, and the consortium charter and membership agreements are due in late 2026.

What's next: - Prometheus will continue through its three-year funding period as the national labs, universities and commercial partners work toward the program's performance targets. - HGP says it intends to build its manufacturing answer in Texas. - The company and its partners still need to finalize participation terms before the collaboration is fully locked in.

The bottom line: - HGP has secured a place in one of DOE's biggest nuclear AI efforts, with a pitch built around making reactors flexible enough to serve data centers without burdening the public grid.
