To achieve its goal of operating entirely on zero-carbon energy by 2030, GoogleAnnounceInvested in Italian startup Energy Dome and established a global commercial partnership, planning to introduce its CO2 battery technology into global data center grids as a key solution for long-duration energy storage (LDES).
Compared to current common lithium battery solutions, which can only store renewable energy for less than four hours, Energy Dome's proposed carbon dioxide battery design can support energy storage and release for 4 to 8 hours, further extending the utilization period of renewable energy and ensuring stable power supply even in conditions of insufficient sunlight or wind.
This dome-shaped energy storage device is filled with carbon dioxide gas. During periods of peak renewable energy generation but low electricity demand, the system uses excess electricity to compress the gaseous carbon dioxide and convert it into liquid form for storage. When electricity demand rises, the liquid carbon dioxide rapidly expands into a high-pressure hot gas, which drives turbines to generate electricity that is fed back into the grid, providing a stable and sustainable power supply that can support demand for up to a full day.
Google stated that this is its first investment in long-duration energy storage technology. Besides being optimistic about the commercial potential of Energy Dome's CO2 battery technology, which boasts high efficiency, scalability, and low costs, it is also believed that its technology is expected to be commercialized faster than other similar clean energy technologies, helping Google's global data centers and infrastructure achieve 24/7 zero-carbon energy operations sooner.
This collaboration and investment is part of Google's long-term commitment to sustainable energy. Over the past few years, Google has deployed solar and wind power plants in numerous locations around the world and partnered with numerous startups to develop innovative energy technologies.
However, to truly achieve 24-hour uninterrupted use of renewable energy, it is still necessary to overcome the challenges of factors such as nighttime, weather changes, and peak electricity consumption. Energy Dome's carbon dioxide energy storage technology just fills this gap.
According to information released by Energy Dome, its energy storage system design not only boasts long-term storage capabilities, but also features a high cycle life, eco-friendly materials, and the ability to be deployed in most regions without specific geographical restrictions, further reducing installation barriers and costs. Energy Dome also plans to accelerate its global commercialization efforts, expanding the scope of its technology's application and market size.
As businesses and governments around the world are actively seeking more efficient and sustainable energy solutions, Google's leading investment in forward-looking new energy storage technologies will not only help it achieve its own ESG commitments, but also drive the entire cloud computing and data center industry towards net-zero emissions goals.
