Abstract
A thermal storage unit having at least one annular flow channel formed between an inner and outer member is provided. The thermal storage unit uses conventional mill products to create annular flow channels that economically maximize the surface area of flow in contact with the thermal mass included in the inner and outer members. This enables the thermal storage unit to economically provide heat storage as well as effective heat delivery and pressure containment for a fluid flowing through the annular channel.
