Quantum for Energy and Utilities 2026

Executive summary Quantum solutions are emerging for energy and utilities in grid optimization, materials discovery and infrastructure security, with near-term gains using hybrid workflows. Leaders should prioritize high-impact cases, benchmark data and scale up when results outperform classical methods. Quantum technologies in computing, sensing, communication and cybersecurity are moving from research to early pilots and entering the energy and utilities sector as an additional set of tools for specific, hard problems. They will not replace classical computing, but they may expand what can be explored, simulated and optimized, particularly when used in hybrid workflows that combine quantum methods with established high- performance computing and AI approaches. The earliest opportunities are concentrated in hybrid quantum-classical optimization, emerging sensing applications and post-quantum cybersecurity upgrades. Over the longer horizon, advances in quantum simulation and sensing could unlock higher-fidelity modelling and measurement that support cleaner, more resilient energy systems. Quantum solutions offer high-impact benefits for targeted use cases across energy and utilities. While hardware for sensing, communication and computing continue to mature, applications are gaining traction across four value pillars (see Figure 1): –Transition and materials acceleration –Operational optimization –Trusted infrastructure and cyber resilience –Precision monitoring and sensingThis report offers business leaders a roadmap to move from low-risk, high-value pilots towards scaling-up quantum alongside high-performance computing and AI.
