GreenFire Energy, EDC to repower Mahanagdong geothermal facility in Leyte

GreenFire Energy Inc. has entered into an agreement with world geothermal leader Energy Development Corporation (EDC) to perform a commercial retrofit that will restore and generate steam from an idle geothermal well in its Mahanagdong geothermal facility located in Leyte, Philippines.

The idle geothermal well has not been used due to the high level of non-condensable gases produced from the well when flowing. The heat mining system will correct this and meet its surface system pressure requirements once it is installed and commissioned in the fourth quarter of 2021. The data and experience gathered with the surface project are part of the collaborative efforts to evaluate the feasibility of using Greenfire GreenLoop™ technology in other opportunity wells of EDC.

GreenFire GreenLoop is a patented, closed-loop geothermal energy system that generates power from geothermal resources where conventional geothermal systems cannot effectively operate, typically due to lack of permeability, water, or pressure. The first demonstration of GreenLoop was performed at the Coso KGRA in California, the USA in 2019 and showed that GreenLoop can retrofit unproductive or idle geothermal wells and run successfully at a field-scale. It is estimated that over 20% of geothermal wells worldwide are unproductive from inception or due to degradation over time and it is further estimated that only 2% of the world’s geothermal resource can be profitably harvested with conventional technology.

GreenFire Energy and EDC are also working together to analyze other unproductive geothermal wells and less productive geothermal fields where the potential for using this technology will be of the greatest technical and economic benefit.
