GoRental SG, Higher Dimension Materials and Pylon City have agreed a collaborative project focused on advancing long-duration energy storage and smart energy systems for Singapore and Southeast Asia.
The partnership is positioned to expand the deployment of renewable energy by filling a widening gap in storage solutions that underpin grid stability and energy security.
Storage gap
The collaboration combines GoRental SG’s distributed renewable power systems, Higher Dimension Materials’ Si707 molten-silicon energy storage technology, and Pylon City’s Nexus System for intelligent energy monitoring and optimisation. The group aims to address the limitations of short-duration battery storage and offer a practical response to concerns about grid reliability and battery safety as Singapore transitions to a cleaner energy mix.
Colin Peh, Founder and Managing Director of GoRental SG, said, “Long-duration storage is no longer a theoretical ambition, it is becoming a practical requirement for communities and businesses seeking stable, clean power. This collaboration is about building solutions that match the realities of the region: systems that are safe, scalable, and grounded in real-world use. Our work through CETRIC allows us to bring together researchers, engineers, and industry partners to speed up that journey, so the benefits of innovation reach the people who need them most.”
Research centre
The agreement supports the activity of the Clean Energy Technology, Research and Innovation Centre (CETRIC), which was co-created by GoRental SG and the Singapore Battery Consortium. CETRIC is designed to bring together researchers, industry, and government to focus on long-duration storage, smart grid development and circular battery technologies in support of Singapore’s Green Plan 2030 and net-zero ambitions for 2050.
The signatories plan to secure between SGD $5 million and $10 million in funding over the next three years. This funding will support CETRIC’s ongoing work and accelerate new technology development and deployment in these areas.
Si707 system
A major project for the group is the roll-out of Higher Dimension Materials’ Si707 system, which uses molten silicon to store renewable energy for up to two weeks. This offers a solution for applications where conventional short-duration lithium-ion batteries may be unsuitable, due to risk, cost, or operational constraints. The Si707 system is being targeted at industrial, grid and remote-energy applications seeking fire-safe and economical storage.
The storage hardware is paired with Pylon City’s Nexus System, a digital platform that tracks emissions, forecasts performance and enables real-time management of distributed assets. This combination is aimed at providing greater transparency and predictive capability for operators navigating the shift to renewable energy.
Industry context
Recent emphasis on Singapore’s transition to renewables has highlighted the importance of developing long-duration storage technologies. National policy discussions and industry analysis have underscored that reliable, safe, and scalable solutions will be critical as more intermittent renewable energy sources join the grid.
