Australian clean-technology manufacturer Graphite Energy has secured $40 million in funding to accelerate the large-scale deployment of its Green Steam thermal energy storage systems. The round comprises a loan facility from Catalytic Impact Capital alongside an equity subscription agreement led by the family office of Lyall and Toni McLachlan, supported by existing shareholders and a new institutional investor. Graphite Energy designs, manufactures, and operates advanced electric boiler systems that use thermal energy storage to capture low-cost renewable electricity and deliver steam at a price point intended to undercut natural gas. The technology allows industrial manufacturers to replace conventional gas boilers with renewable electric heat, reducing both operating costs and carbon emissions. The company is currently installing two Green Steam systems with major multinational food and beverage companies, with eight additional projects progressing through detailed engineering. CEO Peter Lemmich described the funding as a major milestone, citing accelerating customer demand and the company’s increased capacity to deploy at scale.
