The LDES Council leverages the deep expertise of its member base to publish insights on the topic of energy flexibility.

NOVEMBER 2022: Net-Zero Heat: Long Duration Energy Storage to Accelerate Energy System Decarbonization

This report presents the latest view on the role of LDES in helping achieve net-zero power and heat by 2050, focusing on the potential role of thermal energy storage (TES) in realizing net-zero heat. It builds on prior LDES Council research and analysis and presents updated cost perspectives based on data from LDES Council members. As a follow- up to previous LDES Council publications, this report focuses on the heat sector, a pivotal component in achieving global decarbonization and climate targets. Accordingly, it also focuses on a particular set of LDES technologies, TES, which can store heat, decarbonize heat applications, and integrate renewables in this sector and the broader energy system. It highlights the relationship between power LDES and TES to accelerate the energy transition, and the role that TES plays in decarbonizing heat applications.

JUNE 2022: The Journey to Net-Zero: An Action Plan to Unlock a Secure, Net-Zero Power System

Decarbonized and energy secure countries will need Long Duration Energy Storage solutions to provide flexibility and reliability – policies and regulations have key roles in enabling their large-scale deployment. In this report, the Council focuses on potential regulatory and policy options to overcome barriers to widespread LDES deployment. Such measures will be a critical component of an action plan to deliver the energy transition and to ensure a sustainable and secure energy future for all.

The rising share of renewable power in the global generation mix-driven by the need to reduce greenhouse gas (GHG) emissions — has created new challenges in managing electricity supply and demand. In particular, the inherent intermittency of wind and solar power creates a need to balance supply and demand, for example by using fossil fuel power to fill gaps. The search is on for a solution that will further reduce the need for fossil fuels, increase decarbonization, and improve risk management. One answer is 24/7 clean Power Purchase Agreements (PPAs).

Net-Zero Heat

Comprehensive evaluation of heat decarbonization landscape and net-zero pathways with consideration for thermal flexibility (heating and cooling) and storage solutions. Expansion beyond power system flexibility to integrate power, heat, and hydrogen couplings that enable overall energy system flexibility.

This effort places additional emphasis on benchmarking and detailing thermal LDES technologies along with other thermal technologies (e.g., heat pumps, electric furnaces, hydrogen heating).
