The Challenges with Long-Duration Energy Storage In today's critical time, one of the essential issues that every nation faces as a blockage in their clean energy growth is Energy Long-Duration Energy Storage. It is often known as LDES. To address this issue, the Northeast Clean Energy Council (NECEC) hosted a Cleantech Executive Roundtable discussion on modernizing the grid with LDES. This event brought together to discuss along all experts from private and public sectors on - how it can be deployed in the northeast and achieve the most impact. The discussion's goal was to understand better the challenges and opportunities associated with LDES to identify potential solutions.
Background: As the clean energy sector grows, the need for reliable and affordable energy storage solutions becomes more apparent. LDES is a promising option for providing long-duration energy storage, defined as storage that can discharge for 10 hours or more. It can be used to meet a variety of needs on the electrical grid, including load-shifting, loadleveling, ancillary services, peak shaving, and backup power.
The Challenges with Long-Duration Energy Storage: 1. One of the challenges with long-duration energy storage is its high cost. Currently, LDES technologies are not cost-competitive with other forms of energy storage, such as battery storage. This is a significant barrier to adoption. 2. Another challenge is that only some LDES technologies are available now. This lack of options makes it difficult for developers and utilities to find the right solution for their needs. Additionally, many of the existing LDES technologies are still in the early stages of development, which means they still need to be fully mature. This can create reliability and performance issues.
3. Another challenge is that LDES generally requires a larger footprint than other forms of energy storage. This can be a problem in densely populated areas with limited space for new development. 4. One of the key technical challenges with LDES is the need for a standard definition or set of specifications. This makes it difficult to compare different LDES technologies and assess their performance. Additionally, there needs to be more data on their performance under real-world conditions. This lack of data makes it difficult to determine the economic benefits of LDES and compare it to other energy storage options. 5. LDES is a relatively new technology and has yet to be commercially available at scale. This lack of commercial availability makes LDES more expensive than other energy storage options. 6. LDES faces many policy barriers that are hindering its deployment. One of the critical policy barriers is the lack of a federal tax credit for LDES. This makes LDES less economically attractive than other energy storage options that do benefit from a federal tax credit. Additionally, there is currently no federal mandate for LDES, which is a crucial driver of deployment for other energy storage technologies.
Potential Solutions: Despite the challenges associated with LDES, the panelists agreed that it is a promising technology with the potential to provide significant benefits to the electrical grid. To overcome the obstacles and unlock the potential of LDES, the panelists identified several actions that need to be taken. 1. First, there needs to be more collaboration between the public and private sectors to develop a standard definition for LDES. This traditional definition will allow for better comparisons of different LDES technologies and help to overcome the need for more data on LDES performance. 2. Second, the public and private sectors need to work together to reduce the cost of LDES. This can be done through research and development, as well as through the deployment of pilot projects. 3. Third, There is a need for more policy support for LDES at the federal level. This could include a federal tax credit for LDES and a federal mandate for LDES. Such policy support would make LDES more economically attractive and help to drive its deployment.
Conclusion
Long-duration energy storage is a promising technology with the potential to provide significant benefits to the electrical grid. To overcome the challenges and unlock the potential of LDES, the panelists identified several actions that need to be taken. These include more collaboration between the public and private sectors to develop a standard definition for LDES, drive down the cost of LDES through research and development, and policy support at the federal level.
