- Main development in turning photo voltaic and wind into 24/7 baseload
- Brief- and long-duration power storage value aggressive with lithium-ion batteries and pure fuel peaker crops
- Applied sciences will generate extra geothermal energy at half the associated fee
HOUSTON, Sept. 12, 2023 /PRNewswire/ — Sage Geosystems Inc. (Sage), a geothermal baseload and power storage firm, at this time introduced groundbreaking outcomes and information from their full-scale business pilot confirming the efficiency of its power storage system that may present short- or long-duration storage (EarthStore™). Additional, the outcomes present Sage’s expertise is cost-competitive with lithium-ion batteries, pumped storage hydropower, and pure fuel peaker crops. Sage will current their power storage pilot outcomes tomorrow on the PIVOT 2023 convention.
Landmark Outcomes
Brief- and Lengthy-Period Storage. The sphere outcomes from 2022/2023 and intensive information evaluation carried out in 2023 confirmed Sage can present 18 hours or extra of storage capability to successfully generate baseload power 24/7 when paired with photo voltaic or wind technology. The sphere outcomes additionally demonstrated that Sage can alternatively present high-powered, short-duration energy (load-following) throughout peak demand. Each storage intervals, long- and short-duration, improve grid reliability with steady energy output. As well as, the warmth from the formation expands the fluid downhole and improves spherical journey effectivity (RTE).
The Sage information units had been obtained by pumping in and flowing again water from their properly to gauge capability and energy length. No induced seismicity was measured both throughout fracturing or subsequent pumping operations.
Sage’s power storage design is able to scale and isn’t geographically restricted. As well as, it may be utilized in newly drilled wells and in current oil and fuel wells. The pliability of their storage for each short- and long-durations can present optimally timed flows to maneuver power from a time of day (or week or longer) the place the demand is low to a different time when the demand is excessive.
Price Aggressive LCOS (Levelized Price of Storage). Of much more significance, the outcomes confirmed, primarily based on LCOS, that Sage’s power storage can present energy at a value that’s decrease than lithium-ion battery storage and conventional pumped storage hydro. It is also aggressive with pure fuel peaker crops, offering a cleaner possibility for offering ancillary providers, black begin providers, and/or redistributing curtailed power throughout peak demand intervals.
Abstract of Sage’s Business Pilot Outcomes
EarthStore™ is Sage’s mechanical power storage expertise that harvests the stress power of the fluid and can be enhanced by the warmth from the formation.
- Produced 200kW for over 18 hours (long-duration) and 1MW for half-hour (load-following), restricted solely by the small diameter rental floor tools piping.
- Generated electrical energy with Pelton generators to energy tools on location.
- Measured subsurface system efficiencies between 88-94%, with an estimated round-trip effectivity (RTE) of 70-75%.
- The warmth from the formation expands the downhole fluid and improves RTE.
- Measured fluid losses < 2%, reducing to 1% by the top of the 5-week interval.
- Demonstrated the flexibility in a single properly to generate 2-3MW internet output.
- Calculated LCOS that’s cost-competitive to pumped storage hydropower and lithium-ion batteries.
“We’ve got cracked the code to supply the right complement to renewable power, yielding dependable different baseload in a way that’s value aggressive with lithium-ion batteries and pure fuel peaker crops,” mentioned Cindy Taff, CEO of Sage Geosystems. “The alternatives for our power storage to supply energy are vital – from distant mining operations to information facilities to fixing power poverty in distant places. We will interconnect with energy grids or develop island/microgrids with a cleaner power resolution that’s confirmed and able to scale.”
Vitality Transition in Motion – Vitality Storage to Geothermal
Sage’s Enhanced Geothermal Techniques (EGS) geothermal properly design makes use of all the identical applied sciences as their power storage system, which was confirmed earlier this yr. Their distinctive EGS properly design equates to half the price of EGS two-well techniques, and their supercritical CO2 turbine can present extra energy output over conventional generators at the moment utilized in geothermal. Principally importantly, not solely is Sage harvesting the warmth from the downhole fluid, however they’re additionally harvesting the stress leading to a major improve in general system effectivity.
About Sage Geosystems
Sage Geosystems is a quickly rising enterprise devoted to the development and widespread deployment of power storage and geothermal baseload options for a sustainable power future. Based in 2020, Sage brings modern expertise and a staff with a confirmed monitor report of motion and supply. Sage has power storage options that may present both short- or long-duration storage and which are able to scale now, which is more economical than pumped storage hydropower and lithium-ion batteries. Sage’s power storage will be deployed nearly wherever, it has a small floor footprint, and is sustainable, requiring no provide chain. Sage may also drill barely deeper wells to attain elevated temperatures, which achieves geothermal power technology. With experience in drilling, engineering, and information science, Sage Geosystems strives to make geothermal power accessible and reasonably priced for everybody, in all places.
