crossenergy

Crossenergy is an approach in energy system design and policy that seeks to coordinate and integrate multiple energy carriers, including electricity, gas, heat, and transport, across generation, transmission, distribution, storage, and end-use sectors. It emphasizes cross‑sector interactions to increase efficiency, flexibility, and decarbonization.

The concept encompasses technologies and strategies such as power-to-X (including hydrogen, methane, and liquid fuels), power-to-heat, district heating and cooling integrated with electric grids, hydrogen and methane distribution networks, and advanced energy storage that can span chemical, thermal, and electrical forms. It relies on digitalization, interoperable communication standards, and coordinated market designs to manage the flows and prices of different energy forms.

In practice, crossenergy involves planning at the system level, deploying flexible assets, and creating market mechanisms that enable cross‑energy services, such as grid services from thermal storage or gas networks absorbing renewable electricity. It is often framed within broader discussions of energy system integration and sector coupling.

Benefits include improved resilience, higher utilization of renewable generation, reduced peak demand, and lower overall emissions. Challenges involve high upfront costs, regulatory fragmentation, lack of universal standards, data privacy and cybersecurity, and the need for long-term planning horizons.

Crossenergy is discussed in policy and research circles as part of energy system integration and power-to-X strategies, with pilots and demonstration projects in various regions. See also sector coupling, energy system integration, power-to-X.
