Why Synthetic Fuels Are Necessary in Future Energy Systems

We propose a hypothesis that fuels will continue to be critical elements of future energy systems. The reasons behind this are explored, such as the immense benefits conferred by fuels from their low cost of storage, transport and handling, and especially in the management of the seasonal swing in heating demand for a country with a summer and winter season such as the UK. Empirical time-series data from Great Britain are used to examine the seasonal nature of the demand for liquid fuels, natural gas and electricity, with the aid of a daily Shared Axis Energy Diagram. The logic of the continued need of fuels is examined, and the advantages and disadvantages of synthetic fuels are considered in comparison to fossil fuels.

Chapter 3 – CO2-Derived Fuels for Energy Storage

Abstract This chapter examines the manner in which CO2-derived fuels, synthesised using renewable energy, can help with decarbonisation of several sectors. Three areas are discussed: the electrical generation system, transport fuels and energy for heating. In addition, the advantages and disadvantages of such CO2-derived fuels are considered with respect to other energy storage technologies. An introduction to the variations in daily demand on an electrical grid is illustrated by considering a single day experienced by the Spanish grid and the concept of a “generation mix” is presented. Synthetic fuels for transportation are explored alongside alternatives to the internal combustion engine, such as fuel cells and batteries. Finally, the area of heat provision, where CO2-derived fuels can be expected to play a vital role is introduced.
