Metal Hydride Thermal Battery Storage Technology
New Unique Thermal Battery Technology
Much More Efficient Than Lithium-Ion
The Missing Link for Existing Renewable Energy Technologies
“This is Game Changing”
Thermal Energy Storage (TES) is a key technology for implementing renewable energies.
Chemical storage is the technology of storing heat by utilizing reversible chemical reactions.
The Bucky Battery is a whole new way of thinking about capacity and reliability of batteries for the industrial marketplace.
This represents a benchmark in energy storage.
Bucky Batteries stores electricity from any power source in the form of heat and create electricity from that heat.
"The battery uses a high-temperature metal hydride or metal carbonate as the heat storage medium and a low temperature gas storage vessel for storing the hydrogen or carbon dioxide.
At night, and in times of cloud cover, hydrogen or carbon dioxide is released from the gas storage vessel and absorbed by the higher temperature metal to form a metal hydride/metal carbonate, which produces heat used to generate electricity." - Professor Craig
In this reversible chemical reaction, the thermal energy transforms into chemical energy. In the forward reaction, thermal energy serves as the power source to drive the chemical reaction and it is able to store heat by breaking the chemical bonds in the AB molecules, dissociating AB into A and B. Obviously, it is an endothermic process. In the reverse reaction, since the intrinsic property of exothermic reaction, the A and B molecules bind together and produce AB compounds, transforming the chemical energy back to thermal energy and releasing a large amount of heat. During the process of thermal energy storage and release, the most important thing is that the heat is stored in chemical form without any thermal waste and the energy in the chemicals do not fade in a long time
Metal Hydrides will replace molten salts – the current storage technology for large-scale CSP plants. Metal hydrides could be far more efficient. Molten salts are very low energy density at 153 kilojoules per kilogram whereas a metal hydride is between seven to 55 times more energy dense, depending on the hydride used.
Using thermal batteries will revolutionize the landscape of renewable energy production world-wide.
Applications: To firm up renewables projects. As a peaking resource for Utilities, Industry, Goverment. Buckley Bucky Batteries will also be used for peaking power and power grid support.
"Absent battery storage, the whole value proposition of intermittent renewable energy makes no sense at all," said Donald Sadoway, a battery researcher at Massachusetts Institute of Technology.
