This book will provide an overview of combined heat and power (CHP) and district heating (DH) and its potential application for heating buildings and industrial processes, including the implications for energy policy. It will describe why combined heat and power is interesting even in an era of low carbon energy, how it is linked to district heating and why these two technologies together may be an important component of heating legacy buildings in a low-carbon future. The book will explain why district heating can take in any form of heating, not only from power stations (which could be powered by renewable hydrogen) but from waste combustion, industrial waste heat, solar, wind or biofuel or biomass energy. It will also show how, when coupled with the availability of vast and cheap storage, CHP/DH can be a key enabler of renewable energy and energy efficiency.

David Charles Andrews has worked in the energy field for 40 years. His principal activities are in small-scale power generation with CHP, and he was a principal driver of the introduction of gas engine CHP into the UK in the 1980s. He has worked in the practical part of the Combined Heat and Power and Engine Generator industry and has contributed numerous articles and learned papers on the subject and its relevance to energy policy. He chairs the Claverton Energy Think Tank of energy experts and is a member of the District Heating and Cooling online network of experts. For two years he was an Invited Expert and Senior Advisor for Power Generation for the EUs JRC at Petten and produced numerous learned reports, which pointed out methodological errors in the then-current method of modelling CHP, which seriously undervalued its contribution. Over his career. David has written numerous reports and articles covering renewable energy, renewable power generation, district heat and integrating renewables with the power grid.
