Future Energy System

Global electricity generation currently accounts for over 25% of global greenhouse gas emissions (GHG), and electricity demand has more than doubled in the last 30 years. By 2050, it is expected to double again to meet continued population and GDP growth, as well as to cover the electrification of new sectors previously supplied with fossil fuels (such as heating, transport, and industrial processes). As intermittent renewable energy is deployed to decarbonize the power sector, it will be crucial to ensure enough long-duration energy storage (LDES) capacity is implemented, in addition to other energy system flexibility tools. This will guarantee security of supply and avoid massive waste of clean energy during daily, weekly, and seasonal timeframes.

Promote the development and deployment of long-duration energy storage (LDES) technologies to cover storage needs over intra-day, multi-day, and seasonal timeframes. Create a suitable regulatory environment to minimize investors’ risk and promote technology adoption.

The Basics & The Gaps - Thermal Energy Storage

The heat sector plays a crucial role in the global economy and the energy transition: it accounts for 50% of global final energy use and over 25% of global greenhouse gas emissions. How can we decarbonize the heat sector? What role can Thermal Energy Storage play in reaching our net-zero goals? Read our newly released Factsheet!

The Basics & The Gaps - Long Duration Energy Storage

LDES is one of the most crucial pieces of the energy flexibility puzzle, specially for countries reaching high shares of wind and solar power. By incorporating LDES into the grid, utilities can better manage the balance between supply and demand, improve energy security, and reduce curtailment (waste of excess production) of renewable sources.
