Singapore’s Energy Market Authority (EMA) has awarded a grant to Posh Electric, a wholly owned subsidiary of Posh Energy, to pilot a sodium-ion battery energy storage system (BESS). The initiative aims to support Singapore’s shift toward renewable energy by demonstrating a scalable and environmentally sustainable solution for managing solar power intermittency.
Under the program, Posh Electric will develop and deploy a 1-megawatt-hour sodium-ion BESS at Utraco Pte Ltd’s manufacturing facility. The system will integrate with 600 kilowatts of rooftop solar panels to store excess energy during peak sunlight hours and release it during periods of low generation. Posh Electric will collaborate with the Institute of Materials Research and Engineering (IMRE) of A*STAR and Utraco on system design, installation and performance monitoring.
Sodium-ion batteries are increasingly viewed as a potential alternative to lithium-ion technology. Sodium is naturally abundant—more than 1,000 times more plentiful than lithium—and its extraction process typically involves fewer environmental impacts. These batteries also offer inherent safety advantages and could reduce raw material costs. The growing interest in sodium-ion comes at a time when global lithium demand is projected to rise twenty-fold by 2030, placing pressure on supply chains and highlighting the need for diversified storage chemistries.
Dr Wesley Zheng, CEO of POSH, said, “We are thrilled to have received support from the Energy Market Authority for this landmark project. We have, over the years, developed unique battery control hardware and software solutions to manage a wide variety of battery chemistries, including sodium-ion batteries. By harnessing sodium’s natural abundance and integrating it with renewable energy solutions, we aim to provide a sustainable and scalable alternative to conventional battery technologies. This grant is a testament to the innovative approach taken by POSH in battery system integration, and we are eager to demonstrate its benefits to Singapore and beyond.”
Posh Energy specializes in advanced battery technology solutions designed to support the expanding renewable energy sector. Through research and strategic partnerships, the company focuses on overcoming key challenges in energy storage to facilitate the transition to cleaner power sources.
