Posh Electric Awarded EMA Grant for Sodium-ion Battery Project

SAN FRANCISCO, Aug. 5, 2025 /PRNewswire/ -- Posh Energy's fully owned subsidiary in Singapore, Posh Electric ("POSH"), has been awarded a grant from the Energy Market Authority (EMA) of Singapore to conduct a trial of a sodium-ion battery energy storage system (BESS). The project addresses the need for scalable and environmentally sustainable energy storage solutions to support Singapore's transition towards renewable energy.

POSH will lead the development and deployment of a 1-megawatt-hour (MWh) sodium-ion BESS to manage solar intermittency, in partnership with the Institute of Materials Research and Engineering (IMRE) of the Agency for Science, Technology and Research of Singapore (A*STAR), and Utraco Pte Ltd, at Utraco's factory. This BESS will integrate with 600 kW of rooftop solar arrays to store renewable energy, providing load-shifting capabilities and mitigating the intermittency of solar power. Sodium-ion batteries are gaining recognition as a feasible alternative to lithium-ion batteries due to the natural abundance of sodium, cost-effectiveness, and enhanced safety features. Sodium is over 1,000 times more abundant than lithium, and its extraction involves a simpler process with a reduced environmental footprint. Sodium-ion batteries offer a more sustainable and potentially lower-cost solution—a significant development given that global lithium demand is expected to increase twenty-fold by 2030.

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."
