Research grant for Singapore’s first floating energy storage system

The Energy Market Authority (EMA) and Keppel Offshore & Marine have jointly awarded a research grant to pilot Singapore’s first floating energy storage system (ESS).

This project was awarded to a consortium led by Envision Digital International Pte Ltd (Envision Digital).

The floating ESS is part of a $10 million partnership between EMA and Keppel O&M to develop innovative energy solutions in the marine sector announced earlier in April this year.

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). As Singapore’s hot and humid climate can affect the performance of the ESS, the testbed will feature a system that uses 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%. Findings from the project are expected to be applied to ESS on mainland Singapore.

EMA’s Chief Executive, 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. More details of the project can be found in the Annex.

Chris Ong, Chief Executive Officer of Keppel O&M, said: ‘We are proud to work with the consortium led by Envision Digital to pilot the first floating ESS on our FLL. Besides supporting Singapore’s energy needs, the developed solution will have multiple applications such as supporting areas with intermittent power supply, and rapid deployment to provide emergency power for places or remote islands affected by power disruptions.’

The Keppel CEO also emphasised that the project could bring direct benefits to the shipping industry, as the technology ‘can also be deployed on hybrid or fully electric vessels to significantly reduce carbon emissions’.

FueLNG  – the joint venture between Keppel O&M and Shell which is set to launch Singapore’s first LNG bunkering vessel, the FueLNG Bellina, this year – will be providing LNG bunkering services to harbour craft and other small vessels from a dedicated facility on the FLL when it becomes operational.
