A new concept for thermal energy storage You can charge a battery, and it''ll store the electricity until you want to use it, say, in your cell phone or electric car. But people have to heat up their solar cooker when the sun''s out, and by the time they want to make dinner, it may well have given off all its stored heat to the cool evening air.

Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and industrial processes. In these applications, approximately half of the
In general, an Ionic Liquid -literally "liquid salt"- can be defined as any salt that melts (becomes liquid) before decomposing. Ionic liquids are often composed of both organic and inorganic cations and anions. There is an extensively but controversial accepted division of these ionic materials into two groups: the so-called " room
One electricity storage concept that could enable these cost reductions stores electricity as sensible heat in an extremely hot liquid (>2000 °C) and uses multi-junction photovoltaics (MPV) as a heat engine to convert it back to electricity on demand, hours or days, later. This paper reports the first containment and pumping of silicon in a

Latent Heat Storage (LHS) A common approach to thermal energy storage is to use materials known as phase change materials (PCMs).
