Major changes in the energy system, like volatile renewables, hydrogen-based energy carriers, electrification of transport, and residential and industrial uses, drive the demand for European coordinated energy infrastructure (CEI) planning. Energy infrastructure planning is separated into sectoral areas such as electricity and gas networks, heating and cooling, water, and transport, in conjunction with the interrelated telecommunication sector. This separation is, to a growing extent, a problem now that sectors are getting intertwined and interdependent. At the same time innovative technologies and digitalisation are making coordinated energy infrastructure planning possible by providing the industry with more advanced methods and tools. Full energy decarbonisation will be extremely challenging for many energy users that do not have a mainstream alternative means of decarbonised energy delivery e.g. shipping and aircraft. Conversion to an alternative fuel source is unavoidable, with perhaps the most likely solution being either a renewable gas, or electricity. This in turn would add to the growing number of new large user sites of these energy sources e.g. airports, ports, datacentres, industrial and residential centres, etc. The issues with integration of these energy users are, if not explicitly, then implicitly covered in this paper. This is because the sectors that will be required to support these users will in turn require energy infrastructure to be planned to permit this. Cross-energy sector planning will become more crucial as a result. Thus, the challenges of one disruption can be partly addressed through another. Disruptive developments in generation, load and storage in the power system can partly be responded to by using disruptive developments in innovative grid technologies, digitalisation and radically improving cooperation across sectors and borders through CEI planning.
