Abstract
In this chapter, the author explores favorable features of the “hub” concept for islands, including the ability to exploit the meaning of “circular energy resource hubs” approach, where the term “hub” as indicated in literature means the use of multiple energy carriers as interfaces between energy producers, consumers, and transport infrastructure. The author expands the idea to “circular energy resource hubs” by integrating circular economy principles in which we keep resources in use for as long as possible, extract the maximum value from them while in use, then recover and regenerate products and materials at the end of each service life. It demonstrates some interesting advantages in terms of applicability of the concept offered by new theoretical approach. Furthermore, circular energy resource hubs could serve as interfaces between infrastructures and network participants (producers, consumers) or between different infrastructures, representing a generalization or extension of a network node.
