Preface

Paraffin oil and mineral oil are synonymous terms. Fluid paraffin oil is a mineral oil that is a byproduct of unrefined petroleum refining. It is a straightforward, lackluster, unscented, and dull oil, chiefly made from high-bubbling alkane subsidiaries. However, it has the potential as a low-cost energy storage material.

Different forms of energy can be stored, including mechanical, electrical, and thermal energy. Energy storage not only reduces the mismatch between supply and demand but also improves the performance and reliability of energy systems and plays an important role in conserving energy. Thermal energy can be stored during the off-peak period, usually at night, and re-used during the peak period.

This book focuses on the application of paraffin for thermal energy storage. It examines the preparation of paraffin via encapsulation to develop a nonconven-
