Global Technological Revolution in Energy Storage
A global technological revolution is underway, driven by innovators seeking to create a greener world by harnessing the power of wind and solar energy. This has led to a breakthrough in energy storage, combining conventional physics and technology with AI software and material science.
Breakthroughs in Energy Storage
Engineers are working to address the intermittency of solar and wind power by developing mechanical batteries and energy storage devices to provide a backup plan when the wind stops or the sun goes down. The success of the green energy revolution relies heavily on the development of innovative energy storage technologies to stabilize the grid.
Case Study: California’s Energy Crisis
California experienced its first rotating outages in 20 years due to a shortage of electricity during a heat wave. The issue was not a lack of sunshine, but rather the timing of energy demand, as solar power generation decreased with the setting sun, while power-hungry air conditioning systems continued to operate. To prevent such crises, California has been investing in batteries to store surplus solar power generated during the day for use in the evening.
Innovative Energy Storage Solutions
Countries like Switzerland are exploring innovative solutions, such as advanced hydroelectric systems, to build giant energy storage systems. A massive water-powered gravity battery, known as a pumped storage plant, is being built deep inside a mountain near Limon Dam.
Gravitricity and Energy Vault
Companies like Gravitricity and Energy Vault are developing innovative gravity-based energy storage systems to facilitate the wider use of intermittent renewables. Gravitricity’s system involves underground mechanical batteries that can store enough electricity to supply 13,000 homes for 2 hours, while Energy Vault’s design features a crane with six arms that lifts and stacks heavy bricks to store energy.
Energy Storage using Liquid Air
High View Power is developing an innovative energy storage system that utilizes liquid air to store vast amounts of energy over a long period of time, allowing for continuous power generation for days, weeks, or even months. The system works by storing energy in the form of liquid air, which takes up a small amount of space, and then expanding it back into a gas to generate electricity when needed.
Benefits and Potential
The key to long-term storage and a nearly endless supply of power lies in cryogenic liquid tanks, which are readily available and affordable, allowing for easy addition of more tanks to increase energy storage duration without needing new charging or discharging stations. This technology has amazing economies of scale, making it possible to store surplus solar energy in summer for use during winter, and its widespread deployment, alongside other long-duration and shorter-duration technologies, can help decarbonize grids and achieve Net Zero by 2050.
