Technology Roadmap - Energy Storage

One of the key goals of this new roadmap is to understand and communicate the value of energy storage to energy system stakeholders. Energy storage technologies are valuable components in most energy systems and could be an important tool in achieving a low-carbon future. These technologies allow for the decoupling of energy supply and demand, in essence providing a valuable resource to system operators. There are many cases where energy storage deployment is competitive or near-competitive in today’s energy system. However, regulatory and market conditions are frequently ill-equipped to compensate storage for the suite of services that it can provide. Furthermore, some technologies are still too expensive relative to other competing technologies (e.g. flexible generation and new transmission lines in electricity systems). This roadmap reports on concepts that address the current status of deployment and predicted evolution in the context of current and future energy system needs by using a “systems perspective” rather than looking at storage technologies in isolation.
