Carbon capture and storage

With CCS, carbon dioxide is captured from a point source, such as an ethanol refinery or a coal power plant. It is usually transported via pipelines and then either used to extract oil or stored in a dedicated geologic formation.. Carbon capture and storage (CCS) is a process by which carbon dioxide (CO 2) from industrial installations is separated before it is …

An overview of thermal energy storage systems

Thermal energy storage (TES) systems provide both environmental and economical benefits by reducing the need for burning fuels. Thermal energy storage (TES) systems have one simple purpose. That is preventing the loss of thermal energy by storing excess heat until it is consumed. Almost in every human activity, heat is produced.
