Alternative to Hydroelectric Pumped Storage Technologies

Here are samples of newer technologies developed to have a smaller footprint, are environmentally friendly and more efficient

“Hydro One could upgrade its transmission system to allow us to import an additional 2,000 megawatts of peak Quebec water power at a cost of only approximately $80 million. Quebec could provide us with twice as much peak power as the TC Energy project at a capital cost that is 98.14% lower. According to TC Energy, the PSP is the ‘most proven, economical’ way to provide us with 1,000 megawatts of peak power to help phase-out Ontario’s gas-fired power plants. This is simply not true.” – Jack Gibbons, Chair, Ontario Clean Air Alliance.

Hydroelectric Pumped Storage … Explained (1:58 min)

Pumped storage power plants have existed for 100 years – now they are experiencing a revolution. A company from Bavaria will soon store energy in gigantic concrete pistons, which are stuck in a cylinder filled with water. At the Energy Storage Europe – the leading exhibition for energy storage systems of the future we took a closer look.

Tesla’s 52 MWh Battery (55 min)

To achieve a sustainable energy future the world needs reliable, renewable energy around the clock. The island of Kauai has an abundance of solar energy but it can only be used when the sun is shining. Kauai burns millions of gallons of fossil fuels annually to produce energy at night. Until now. Tesla’s 52 MWh Tesla Powerpack and 13 MW solar farm will store solar energy produced during the day and deliver it to the grid during the evening hours to reduce the amount of fossil fuels needed to meet energy demand. This dispatchable solar project represents the first time a utility contracted for a system of this scale that stores and delivers solar energy after sunset.

Storing energy in concrete blocks (1:45 min)

A concrete “battery” could be the future of energy storage. Energy Vault, a Swiss startup, has created a way to store electricity in concrete blocks. The technology helps use solar power when sun doesn’t shine and wind power when the wind doesn’t blow. It’s a low-tech alternative to lithium-ion batteries.
There’s been a lot of progress in renewable energy with solar and wind power, but renewable energy storage remains a challenge. Energy Vault’s idea is similar to hydroelectric power, but instead of using water and dams, it uses concrete blocks and cranes. The low-cost, low-tech solution is proof that some of the answers to our energy-storage problems may be hiding in plain sight.
