Solar Thermal Energy for Industrial Uses

Energy Storage Options Large scale thermal energy storage is a nascent market but it can compensate for the inherent variability of sunlight. For low and medium temperatures, this can usually be performed by storing the heat in a transfer fluid like hot water or oil. Sometimes pressurized steam is used.

Heat Transfer: Conduction, Convection, and Radiation

This is called heat transfer. (Remember, we learned that energy transfer is when energy moves from one thing or place to another, but the energy type stays the same). Heat can transfer (or move) in 3 ways: conduction, convection, and radiation. As you read about the …

Energy Transfer and Conversion Methods

Heat Transfer • For heat to be transferred at an appreciable rate, a temperature difference ( T) is required. – Q = U A T – The non-zero T guarantees irreversibility – As T does to zero, area and cost goes to infinity 22 Sustainable Energy – Fall 2010 – Conversion – -
