Graphite Energy Secures $40M in Funding, Including $15M Loan and $25M Equity

Why It Matters

The financing enables rapid rollout of a proven low‑carbon heat solution, helping heavy‑industry manufacturers meet decarbonisation targets while cutting operating expenses.

Key Takeaways

• Secured $40M AUD (~$26M USD) funding
• Funding split: $15M loan, $25M equity
• Green Steam replaces fossil boilers with zero‑carbon steam
• Two installations underway, eight in engineering
• Reduces emissions and operating costs for manufacturers

Pulse Analysis

Thermal energy storage (TES) is emerging as a cornerstone of industrial decarbonisation, and Graphite Energy’s recent financing underscores the sector’s growing investor confidence. By securing a $15 million loan and a $25 million equity infusion, the Australian firm now has the liquidity to move from pilot projects to commercial‑scale rollouts. This capital injection aligns with global trends where private capital is increasingly directed toward technologies that can bridge the gap between renewable electricity and high‑temperature process heat, a challenge that has long limited the greening of heavy industry.

The Green Steam system differentiates itself by retrofitting existing boiler plants rather than requiring costly new infrastructure. It captures surplus renewable electricity, converts it into high‑temperature steam, and releases that steam on demand, effectively acting as a thermal battery. Early adopters, such as a Mars pet‑food factory in Wodonga, have demonstrated immediate operational benefits, including lower fuel costs and a measurable drop in carbon intensity. The technology’s plug‑and‑play nature reduces implementation risk, making it attractive to manufacturers across food and beverage, chemicals, and other process‑intensive sectors that face tightening emissions regulations.

Looking ahead, Graphite Energy’s funding milestone could catalyze broader market adoption of TES solutions. As governments worldwide tighten climate policies and carbon pricing mechanisms become more prevalent, the economic case for zero‑carbon steam strengthens. Moreover, the involvement of boutique financiers like Catalytic Impact Capital signals a maturing investment ecosystem that values both environmental impact and scalable commercial returns. If Graphite can successfully deliver on its pipeline of ten projects, it may set a benchmark for how thermal storage can accelerate the industrial transition to a low‑carbon future.

Deal Summary

Australian clean‑tech firm Graphite Energy announced it has secured $40 million to scale its Green Steam thermal energy storage systems. The financing comprises a $15 million non‑dilutive loan from Catalytic Impact Capital and a $25 million equity subscription led by the family office of Lyall and Toni McLachlan and a new institutional investor. The capital will accelerate deployment of renewable‑powered steam solutions for industrial customers.
