GreenFire Energy Inc. (GreenFire Energy) and Toyo Engineering Corporation (TOYO) have signed a Memorandum of Understanding (MOU) to jointly deploy GreenFire Energy’s Advanced Geothermal Systems (AGS) in the Asia Pacific region. The initial focus of the partnership will be Japan and Indonesia, while future collaboration opportunities are eyed in North America.

The partnership aims to utilize GreenFire Energy’s patented closed-loop and advanced geothermal systems, which enable operators to tap heat and reinvigorate wells that conventional methods leave behind. GreenFire Energy will provide its subsurface modeling, technology deployment, and retrofit execution, while TOYO layers on its engineering, procurement, construction, and digital-optimization services to deliver a turnkey geothermal solution to premium, baseload megawatts.

Both Japan and Indonesia are rich with geothermal resources and already have many operational geothermal fields that could benefit from the new technology. The aim of GreenFire Energy and TOYO is to work with customers in these markets to revitalize the existing sites, unlocking more value from existing assets and further expanding access to geothermal power.

The partnership offers a comprehensive solution package for revitalizing underperforming geothermal assets in Asia Pacific, a region that holds the majority of the world’s geothermal production. In the United States, where GreenFire Energy originates and owns its geothermal projects, the companies will also explore opportunities for TOYO to provide engineering services and project delivery support. Together, GreenFire Energy and TOYO will identify candidate sites, conduct joint feasibility studies, and deliver AGS retrofit projects that extend the life of existing infrastructure and expand access to low-carbon, resilient power across the region.

“This partnership marks a leap forward for premium, baseload geothermal power in Asia,” said Rob Klenner, President of GreenFire Energy. “Our closed-loop technology has demonstrated its ability to help improve recovery in existing assets; partnering with TOYO scales and streamlines field deployment. Together we can turn under-performing geothermal assets into high-value generation hubs that raise capacity, lower risk, and accelerate speed-to-power for operators across the region.”
