GreenLoop is GreenFire Energy's closed-loop Advanced Geothermal System (AGS) for generating baseload power from existing and new geothermal resources.

GreenFire Energy engineers next-generation geothermal systems that deliver firm, scalable baseload power to industrial customers.
GreenFire Energy engineers next-generation geothermal systems built for real-world operating conditions, repowering existing geothermal assets and enabling new greenfield development. Its single-well, multi-well, and hybrid configurations reduce development risk and shorten project timelines, and the company operates field-validated systems at megawatt scale. The approach is technology-agnostic, spanning advanced geothermal systems, enhanced geothermal systems, and conventional geothermal resources.
The company supplies scalable, behind-the-meter baseload power to energy-intensive industries including data centers, defense, and heavy industry, and it revitalizes underutilized fields using advanced heat recovery alongside proven oil and gas technology. GreenFire Energy holds a growing international patent portfolio and collaborates with partners including Baker Hughes, H&P, and Vallourec. It targets 150 megawatts of capacity by 2030 and aims to rank among the top global geothermal producers by 2040.
