US federal critical technology list drops data centers, batteries, and AR while adding post-quantum cryptography and integrated photonics

The White House’s updated Critical and Emerging Technologies (CET) list reflects a strategic realignment of federal priorities. By removing data centers, batteries, and augmented reality, the administration signals confidence in private-sector capacity to drive progress in these areas. This decision aligns with the broader funding guidance, which directs agencies to avoid competing with commercial investment. For engineers, this means federal R&D dollars will likely shift away from these domains, though existing projects may still receive support until funding cycles adjust.

The additions to the list, post-quantum cryptography, integrated photonics, high-entropy alloys, and hardened consumer operating systems, highlight areas where the government sees gaps or vulnerabilities. Post-quantum cryptography, for example, addresses long-term threats to encryption from quantum computing, while integrated photonics could accelerate advancements in high-speed data transmission. Engineers working in these fields should anticipate increased federal interest, including potential funding opportunities, export restrictions, or collaboration requirements with national security agencies.

The revised list also streamlines categories, merging or renaming some while eliminating others entirely. For instance, advanced gas turbine engines and human-machine interfaces were removed without direct replacements, suggesting a narrower focus on technologies with broader applicability. The semiconductor category, now expanded to include integrated photonics and 2D materials, remains a high priority, with six of seven national security needs mapped to it. This underscores the continued importance of semiconductor innovation, even as the list de-emphasizes other hardware-related areas like data centers.

The changes will have immediate implications for export controls and foreign investment reviews. Technologies added to the list may face stricter scrutiny under export regulations or Committee on Foreign Investment in the United States (CFIUS) reviews. Conversely, removed technologies could see relaxed restrictions, though existing rules may persist until formally updated. Engineers in industries like aerospace or clean energy, where categories were removed or consolidated, should monitor how these shifts affect compliance requirements or international partnerships.

The CET list’s role in shaping federal R&D funding means the revisions could redirect resources toward the newly added technologies. Agencies are instructed to prioritize areas where public investment can complement rather than duplicate private efforts. For engineers, this could translate into more grants or contracts for post-quantum cryptography or integrated photonics, while projects in data centers or batteries may need to rely more on private funding. The list’s emphasis on national security also suggests that proposals with dual-use applications, military and civilian, may receive favorable consideration.
