Quantum for Energy and Utilities 2026

Introduction1 Quantum technologies are emerging as complementary tools for energy and utilities, offering potential improvements in efficiency, measurement sensitivity and data security. Quantum technologies are gradually moving from research and experimental study to early-stage deployment, presenting new opportunities for efficiency and reliability improvements in the energy and utilities sector. While many capabilities remain at a developmental stage, early findings indicate that these tools can complement existing digital systems and support more informed decision- making in complex energy environments. Quantum technologies comprise three broad areas as follows: Quantum computing may help with optimization and simulation tasks that strain classical methods, potentially improving grid planning, asset scheduling and materials research. Real-world impact will depend on continued advances in hardware and software, but over time quantum algorithms could enable more accurate modelling and smoother renewable integration. Quantum sensing can boost measurement sensitivity and data quality in certain operations. By detecting subtle magnetic or gravitational variations, it may improve subsurface characterization, anomaly detection and monitoring of storage or transmission assets, supporting more predictive maintenance and safer performance. Broad deployment, however, still requires validation in real conditions. Quantum communication, including quantum key distribution (QKD), can add protection for critical data flows as networks become more connected. It will not replace today’s security stack soon, but it can strengthen layered defences and help prepare for future cryptographic risks. For further technical insights, refer to resources on the World Economic Forum’s Quantum Economy Network, such as: quantum fundamentals, quantum economy and quantum security. This white paper was developed to combine breadth of perspectives with depth of analysis, drawing on workshops, surveys and expert interviews to test assumptions, challenge early hypotheses and ground recommendations in evidence (see Figure 2). 1.1 Methodology Methodology FIGURE 2 Working group workshops 3 community workshops Total participants: 100 –Brought together diverse set of participants from industry, academia, technology companies, government and policy organizations –>65% of attendees executives or middle managers –~28% represented energy and utilities sector –~90% based in Europe, North America, Middle EastSurveys 7 survey types Total participants: 65 Shaped the direction and content of the paper, covering: –Adoption drivers –Application timelines –Near-term applications –Challenges –Actions to overcome challenges –Use-case selection –Implementation roadmapsConsultant interviews 10 interviews Total interviewees: 15 Conducted multiple interviews with selected executives and experts from industry, academia, policy and technology companies to obtain insights on current and future vision of the technology in energy and utilities Note: The percentage values in the community insight figures (blue bar graphs) indicate the percentages of participants who have selected a particular option.
