Okay, hear’s a breakdown of the key โฃinformation from the provided text, organized for clarity.
Main Idea:
Google is investing in long-duration energy storage (LDES) โขtechnology, specifically partnering with Energy Dome, to create a more reliable, carbon-free electricity grid powered byโข renewable energy. This is a โขcrucial โstep โขtowards Google’s goal of 24/7 clean energy availability.
Key Points:
The Problem: โคRenewable energy sources โฃ(wind, solar) are intermittent. lithium-ion batteries are good for short-term storage (upโข to 4 hours), but longer durations require different solutions.
The Solution: Energy Dome’s LDES Technology:
โ Uses a unique CO2 battery system.
Stores excess renewable energy by compressing CO2 into a liquid.
Releases the CO2 as hot gas to power a turbine when electricity is needed.
โข Provides storage for 8-24 hours.
Is โฃa โคclosed-loop system, producing carbon-free electricity.
Benefits of LDES:
Bridges the gap between renewable energy generation and electricity โdemand.
โ
Increases grid reliabilityโ and flexibility.
Possibly reduces the cost of integrating renewable energy.
โข
โ Could save the world $540 billionโฃ annually by 2040 (according to LDESโ Council estimates).
Improves electricity system stability.
Energy Dome’s Progress:
โฃ Has a working commercial demo facility in Italy (operating for 3+ years).
โค
is building a full-scale 20MW-200MWh facility.
โ โค
Has secured contracts in the US and โIndia. Google’s โขRole:
Investing in and supporting Energy Dome’s commercial projects.
Aims for global request of the technology before 2030.
โค
Exploring other LDES technologies.
โ Demonstrates โcommitment to 24/7 clean โenergy and a green โeconomy.
