- The Energy Market Authority (EMA) has awarded grants totalling $7.8 million to two companies to explore solutions that could enhance the cost-effectiveness and optimise the space required for energy storage systems (ESS). ESS play an important role in supporting the adoption of more solar energy as it mitigates the intermittency of renewable energy sources by storing and discharging energy when required. ESS can also play a role to mitigate power supply disruptions.
- The two research and development projects were selected based on their potential to be scaled up, as well as their potential advantages in Singapore’s context. The projects are:
- Posh Electric’s trial on the use of sodium-ion batteries (SIBs) in ESS. As sodium is more naturally abundant than lithium, SIBs could potentially be a cheaper alternative to conventional lithium-ion batteries (LIBs) in the future. (Please refer to the Annex for more information)
- VFlowTech’s study on the potential for locating ESS underground. Locating ESS underground will minimise the land required, but will also require a better understanding of its safety parameters, including fire safety. This study will also test the use of a lithium-ion/vanadium-flow hybrid battery system. (Please refer to the Annex for more information)
- Mr Puah Kok Keong, Chief Executive, EMA said: “As Singapore expands solar deployment, energy storage systems will become more important to enhance grid resilience and ensure power system stability. I welcome the development of energy storage systems that are safe, cost-effective and space-efficient.”
