More Efficient Control of Energy Systems Versus Rising Electricity Demand: Fraunhofer Researchers Describe What New Digital Technologies Mean for the Energy Sector.

Three technologies, two key questions: “How will quantum technologies shape digital development in the coming years? And what new opportunities will arise when they interact with artificial intelligence (AI) and blockchain technologies?” The Fraunhofer Institute for Communication, Information Processing, and Ergonomics (FKIE) has been addressing these questions. In a white paper, the scientists describe the interactions between quantum technologies, AI, and blockchain, as well as their potential for the economy. Their conclusion: When combined, this trio can significantly improve the mapping, modeling, optimization, and validation of complex energy systems.

Quantum computing opens up new possibilities for solving highly complex optimization and simulation tasks, according to the section titled “Sustainability, Energy, and Climate Systems.” According to the FKIE, the applications range from grid planning, load forecasting, and the use of storage to the optimization of energy storage systems and the integration of renewable energy. Thanks to increased computing power, it will be possible in the future to develop more physically realistic models and faster decision-making processes for power grids and energy markets.

Quantum sensor technology provides highly precise measurement data for environmental, infrastructure, and energy systems. The researchers see potential applications in monitoring greenhouse gas emissions, line and grid conditions, and the measurement of local climate parameters.

Cross-Sector Optimization

In materials and energy research, quantum simulations support the development of new storage technologies, more efficient catalysts, CO2 reduction processes, and materials for hydrogen and power-to-X applications. At the same time, quantum sensors enable more precise condition monitoring of batteries, grids, and storage systems, thereby improving lifespan predictions and resource efficiency.

According to the scientists, the circular economy can also benefit from this convergence of technologies. Digital twins, quantum-based optimization methods, and AI allow for more efficient management of material, energy, and emissions flows. Blockchain technologies complement these approaches by providing tamper-proof traceability along supply, usage, and recycling chains, the report continues.
According to the Fraunhofer Institute, the operation of future energy systems will yield particular advantages in the cross-sector optimization of electricity, heating, transportation, and industrial systems. Quantum and AI-based methods could reduce uncertainties in the feed-in of renewable energy, optimize load flows, flexibly control storage, and support resilience analyses for critical energy infrastructures, according to one finding. In climate modeling, quantum algorithms also enable a more detailed representation of atmospheric and oceanic processes, as well as complex interactions between the energy, transportation, and industrial sectors.

Life-Cycle Assessment

The white paper also highlights the growing energy demand caused by these new technologies. While modern quantum algorithms could potentially operate more energy-efficiently than classical methods for “certain problem classes,” the experts explain that significant energy consumption arises primarily from cryogenics, control electronics, and specialized hardware.

They speak of a “tension between high primary energy and resource requirements and potential long-term efficiency gains, the net effect of which is largely determined by technological scalability, energy sources, and regulatory frameworks.” The FKIE urges that the environmental benefits of these technologies be weighed against their own resource consumption over their entire life cycle.

“Technological developments such as quantum computing or AI are no longer distant visions of the future, but are already increasingly intertwined today, thus forming fundamental building blocks of tomorrow’s strategic value creation,” says Fraunhofer researcher Professor Rene Bantes. “Anyone who views this technological convergence in isolation or ignores it risks missing out on fundamental opportunities for competitiveness, sustainability, and technological sovereignty.”
