Renewable energy must be stored so that people who are dependent on it for the day to day activities can use it even after and before the sunset without any need to wait for the wind to blow. The lack of technologies and methods of storing this energy is the biggest barrier for the individuals who are dependent on it.
What is Metal-organic framework?
Metal-organic frameworks can be defined as 2-dimensional structures that stores and absorbs an enormous amount of gases like carbon dioxide and hydrogen. Its natural porosity reduces material mass and permits lighter and more compact device.
Metal-organic frameworks are tiny, ultra-thin, flexible and super porous crystalline structures. Thousands of scientists searched for this type of material for long which can revolutionize renewable energy storage and harvesting process. They used it not just to store hydrogen and other gases but also to capture and convert carbon into fuels. One of the biggest cons is its lack of conductivity.
Research on Metal-organic framework
According to recent research conducted by USC scientists, metal-organic frameworks can conduct electricity just like any metal. This research proved that one-day metal-organic frameworks can effectively store a large amount of renewable energy. Their discoveries were disclosed in the American Chemical Society Journal.
Tandem possess metallic conductivity and other catalytic properties which increases its renewable energy storage and production potential.
The amount of energy sun provides within 1 hour to the earth is more than the amount of energy entire planet can absorb in 1 year. However, the energy given by sunlight can’t be used because of the lack of sources to conserve it. This intermittency is fundamental to almost every renewable power source, making harvesting and storing impossible unless the weather is good and the sun is shining.
Scientists and industries have the capability to work every day to reduce intermittency. Their consistent work can turn the solar energy into a permanent and enduring resource.
Metal or semiconductor
Metal-organic frameworks have sulfur, cobalt, and carbon atoms. It is a lookalike of graphene, which is transparent material’s thin layer. In summer months, semiconductors turn more conductive. In winter months, metals turn more conductive.
The researcher of Marinescu’s group conducted an experiment using a cobalt-based metal-organic framework. Their metal-organic framework mimicked the conductivity at different temperatures of both semiconductor and metal. It showed conductivity at both too high and too low temperatures.
