While carbon dioxide is typically associated with climate change, Google is looking to use it as a tool to combat the issue. The tech giant has recently partnered with Italian company Energy Dome to explore a new method of storing clean energy using carbon dioxide.
This collaboration aims to implement long-duration energy storage systems, also known as LDES, at Google’s renewable energy projects worldwide. The concept is straightforward yet innovative: store excess energy during peak wind and solar production, and release it when renewable energy generation is low.
Traditional batteries can only offer about four hours of backup power, which may not be sufficient during extended periods of low production. Energy Dome’s solution presents a more effective alternative.
Why Google Opted for the CO2 Battery
Google chose Energy Dome’s CO2 Battery due to its ability to provide clean, dispatchable energy for up to 24 hours. Unlike lithium-ion systems that rely on costly materials, this battery utilizes readily available mechanical components and simple physics.
Instead of storing electricity chemically, the CO2 Battery compresses carbon dioxide gas into a liquid for storage. When additional electricity is needed, the system heats and expands the liquid CO2 back into a gas, powering a turbine that generates electricity.
Scalable, Reliable Clean Power Storage
Google’s support could accelerate the global adoption of this technology, addressing the intermittency of renewable energy sources like wind and solar. Energy Dome’s CO2 Battery offers a solution to store excess renewable energy and release it as needed, supporting stable power grids for communities.
The spinning machinery in the battery adds natural inertia to the grid, enhancing power flow stability as traditional fossil fuel plants phase out. By investing in Energy Dome and planning commercial deployments globally, Google aims to achieve its target of operating on 24/7 carbon-free energy by 2030.
Impact and Benefits
This advancement in energy storage will not only benefit Google but also communities worldwide by providing reliable electricity even in adverse weather conditions. Cleaner energy storage reduces reliance on fossil fuels, lowering emissions and enhancing grid resilience for various establishments.
The scalability of the CO2 Battery offers the potential for broader access, improving energy affordability and security as the technology expands globally.
Kurt’s Insights
Google’s collaboration with Energy Dome offers a practical solution to the demand for continuous clean energy. By storing and releasing power using carbon dioxide, this innovative battery model presents a cost-effective, scalable, and sustainable approach to clean energy. With ongoing investments and projects, the future of clean energy could arrive sooner than anticipated.
