HydroGraph Provides Update on Expanded U.S. Federal Government and Defense Focus, Calls for Graphene to Be Designated a Critical Material

States that Secure Domestic Supply of High-Performance Graphene Is A Key Component to National Security and Reduced Foreign Dependence

AUSTIN, Texas, July 23, 2026 (GLOBE NEWSWIRE) — HydroGraph Clean Power Inc. (CSE: HG) (OTCQB: HGRAF) (“HydroGraph” or the “Company”) today provided an update on its activities in the federal government and aerospace & defense markets as part of its expanded focus on United States national strategic interests and domestic supply chain initiatives.

HydroGraph is encouraging U.S. policymakers to designate graphene a critical material as part of the nation’s broader strategy to reduce the defense industrial base exposure to foreign-controlled graphite supplies and other minerals. The vast majority of graphene produced today is derived from graphite.   Approximately 80% of the global graphite supply is sourced from China¹, which is currently scheduled to become subject to export licensing restrictions in November 2026 unless the current temporary suspension of those regulations is extended.

HydroGraph has demonstrated that high-quality graphene can be produced today from U.S.-sourced hydrocarbon gases rather than mined graphite, providing a fully domestic pathway to the advanced materials needed for next-generation American defense manufacturing.

HydroGraph graphene has shown significant improvements in material strength, thermal and electrical conductivity, lubrication, and protection for applications ranging from lightweighting of aerospace structures, electromagnetic shielding, protective coatings, thermal management, lubricants, and infrastructure. The nano-scale fractal graphene produced by HydroGraph allows for better dispersion versus larger size graphene produced from graphite feedstocks. Better dispersion of fractal graphene allows for mechanical, thermal, and conductivity benefits to be realized at very low loadings, often at under 0.1%.²  

“This is bigger than any one program or platform — it’s about whether the United States controls the materials critical to its defense industrial base,” said Dr. Robert Yancey, Vice President of Business Development – Government and Defense at HydroGraph. “China’s export licensing suspension isn’t a resolution, it’s a reprieve. The legal authority to reimpose graphite export controls remains fully intact and can be activated with 30 days’ notice. Domestic graphene addresses that vulnerability at the source, because the feedstock is hydrocarbon gas, not mined graphite, so there’s no upstream exposure to China.”

HydroGraph also noted that the United Kingdom, the European Union, South Korea, and China have each launched government-funded national graphene programs, while the United States has not. The company is calling on U.S. policymakers and defense stakeholders to take three near-term actions to close that gap: 1) formally designate graphene as a critical material under the Defense Production Act; 2) fund qualification pilot programs to validate graphene across priority defense applications; and 3) establish a dedicated national graphene innovation and research institute to align materials science with long-term industrial and security needs.

“The research base already exists in U.S. universities, national labs, and government research centers — this is not a scientific gap, it’s a policy gap,” said Kjirstin Breure, Chair, President, and CEO of HydroGraph. “China, the EU, South Korea, and the UK are already treating graphene as a strategic material central to their national security planning. The United States still has a first-mover advantage in fielding domestic graphene at scale, but that advantage shrinks every month we wait. We believe securing this supply chain now is one of the clearest, most achievable steps the U.S. can take to protect its long-term national security.”

About HydroGraph
HydroGraph is a leading producer of pristine graphene using an “explosion synthesis” process, which allows for exceptional purity, low energy use, and identical batches. The quality, performance, and consistency of HydroGraph’s graphene follow the Graphene Council’s Verified Graphene Producer® standards, of which very few graphene producers are able to meet.
