MoU signing between Sage Geosystems and ABB

ABB and Sage Geosystems (Sage) have signed a Memorandum of Understanding (MoU) agreement to collaborate on developing energy storage and geothermal power generation facilities that utilize natural heat from the earth’s core to produce clean electricity.

The collaboration will allow ABB to support Sage’s agreement with Meta, the parent company of Facebook and Instagram, to deliver up to 150 MW of geothermal baseload power at a location east of the Rocky Mountains in the US. The first phase of the project is expected to be operational by 2027.

Within the main MoU scope, ABB will investigate how its automation, electrification and digital technology can be deployed at geothermal sites around the world, to maximize energy efficiency and reliability. This may include supplying a distributed control system (DCS), electrical infrastructure architecture, and digital solutions such as asset performance management, process optimization and cybersecurity systems.

The partnership also has the potential to develop solutions for Sage’s energy storage technology, which can be paired with intermittent renewable resources such as solar and wind.

“We are focused on scaling our proprietary Geopressured Geothermal Systems (GGS) technology and our partnership with ABB will advance the widespread deployment of next-generation geothermal,” said Cindy Taff, CEO of Sage Geosystems. “Unlike traditional renewable energy sources, geothermal solutions, including energy storage and baseload power generation, can provide an on-demand source of clean energy that is available 24 hours a day, 365 days a year.”

The GGS process involves pumping fluid at pressure into a man-made subsurface reservoir. After the stored water is heated to more than 150°C and, leveraging pressure or mechanical energy, it can be released back to the surface to pass through heat exchangers and turbines to generate electricity.

“To be able to exploit the potential of geothermal energy to enable a low-carbon society, we need cross-industry collaborations to drive advancements in the technology,” said Per Erik Holsten, President of ABB Energy Industries. “Sage’s GGS offers the ability to produce low carbon electricity, as well as an energy storage solution, and can play an important role in the energy transition alongside other measures.”
