Electrification



Semiconductor fabs are among the most energy-intensive manufacturing facilities in the world, with total demand ranging from 100–1000+ MW at megafabs. Historically, much of this energy footprint has been powered by grid electricity supplemented by on-site fossil fuel systems (boilers, gas-fired turbines). The transition to full electrification and decarbonization is emerging as both a sustainability imperative and a national security priority. While fabs already rely heavily on electricity, several process utilities remain carbon-intensive and are targets for electrification.


Where Electrification Applies

  • Thermal Processes: Some fabs use fossil-fuel boilers for hot water and steam; these can be replaced by electric boilers and high-temperature heat pumps.
  • HVAC Systems: Cleanroom air handling and chillers can transition to fully electric systems powered by renewables.
  • Compressed Air: Pneumatic tools and controls can be shifted to electrically driven compressors with energy recovery features.
  • On-Site Transport: Forklifts and intra-fab logistics vehicles are moving from LPG/diesel to battery-electric platforms.
  • Backup Power: Diesel gensets can be replaced with battery energy storage systems (BESS) or fuel cells tied to renewable hydrogen.

Challenges to Electrification

  • High Thermal Loads: Processes requiring extreme temperatures (oxidation, deposition, diffusion) are difficult to electrify efficiently.
  • Reliability Requirements: Electrified systems must meet the 24/7 uptime and tight tolerance demands of semiconductor production.
  • CapEx & Retrofit Complexity: Converting existing fabs to all-electric infrastructure can be prohibitively expensive.
  • Power Supply: Local grids must scale renewable and nuclear baseload capacity to meet massive fab demand reliably.

Strategic Importance

  • Carbon Reduction: Scope 1 emissions (direct fuels burned onsite) are eliminated by electrification.
  • Grid Synergy: Electrified fabs can align with renewable PPAs, co-located solar/wind, and microgrids.
  • National Security: Electrification reduces dependence on imported fuels and improves resilience in strategic fab hubs.
  • Innovation Catalyst: Electrification creates opportunities for new technologies — e.g., solid-state transformers, smart microgrids, and AI-driven energy management.

Representative Pathways
