Singapore’s first floating energy storage system awarded research grant

Singapore, 3 November 2020 – The Energy Market Authority (EMA) and Keppel Offshore & Marine (Keppel O&M) have jointly awarded a research grant to pilot Singapore’s first floating Energy Storage System (ESS). This project was given to a consortium led by Envision Digital International Pte Ltd (Envision Digital) as part of the S$10 million partnership between EMA and Keppel O&M.

Keppel O&M will be working with the consortium to deploy a 7.5 MW/7.5MWh lithium-ion battery ESS on Keppel O&M’s Floating Living Lab (FLL). This will be Singapore’s largest ESS deployment to date, with sufficient capacity to power more than 600 four-room HDB flats a day. As Singapore’s hot and humid environment can affect the performance of the ESS, the testbed will use an innovative liquid-cooling solution that utilises seawater to cool the battery cells and enhance the lifecycle of the ESS.

The ESS will also explore the first-of-its-kind battery stacking solution in Singapore. This could potentially reduce the footprint required for deployment by up to 40 per cent. Findings from the project are expected to be applied to ESS on mainland Singapore. This would help support power grid stability and resilience, as well as facilitate the adoption of more renewable energy such as solar.

EMA’s CEO, Ngiam Shih Chun, said, “Energy storage and smart energy management systems support the deployment of more renewable energy in Singapore. This project will pave the way to overcome our land constraints, and set the blueprint for similar deployments in the future. We hope to continue co-creating more of such energy solutions with the industry as we work towards a more sustainable energy future for Singapore.”

The ESS will also be integrated with a Smart Energy Management System (SEMS) on the FLL to enhance its operational efficiency. Supported by artificial intelligence and machine learning algorithms, the SEMS will optimise the efficiency of operations and reduce overall energy usage. The project is expected to be completed in 2023.
