The objective of this paper was to design energy integrated solid oxide fuel cell (SOFC) based microcombined heat and power (micro-CHP) systems using syngas derived from lignocellulosic biomass waste.The novel contributions of this work include 1) integration of syngas between a community-scale biomass gasification plant and SOFC based micro-CHP systems in buildings; 2) heat integrated designs of SOFC based micro-CHP systems; 3) integration between SOFC and other heat-led renewable technologies, such as, syngas boilers, ground source heat pump (GSHP) and air source heat pump (ASHP). Conceptual process design frameworks including detailed heat recovery strategies were developed using Aspen plus.It is demonstrated that increases in heat integration between the SOFC inlet and outlet gases enhance the power-to-heat generation ratio from the SOFC albeit at a higher cost of heat exchanger area. A straw (14.6 MJ/kg LHV) based community-scale gasification plant can generate 50-100 kW e of electricity at an overall CHP generation efficiency of ~42%, while if integrated to SOFC based micro-CHP systems (1 kW e ) in individual dwellings via syngas, the overall energy efficiency can be greatly enhanced to ~85%. It is envisaged that the SOFC should be operated at the highest electrical efficiency based on optimal heat integration, however, this needs to be coupled to other heat-led renewable technologies in order to meet the high residential heat to power demand ratio in the UK. Around 2.2 times more syngas may be required in boilers for supplementing residential heating. In integration with a GSHP loop, the flue gas from SOFC can itself be used as a refrigerant and energy integration between the two systems can achieve an overall efficiency of ~90%.

In the past, the major research emphasis in process design has been placed on the analysis, or simulation of processes. The synthesis of processes or process integration has, in comparison, received little attention. This article will discuss the evolution of process integration technology over the past two decades and outlines the problem of chemical process design and then discusses pinch analysis, which developed against the background of the energy crisis of the late 1970s. This article will describe the state‐of‐the‐art developments that have been made in process integration and that build on the foundations laid by pinch analysis and mass integration. It will describe how the design tools have evolved from purely graphical, thermodynamic approaches to incorporate the latest mathematical optimization techniques. Process integration can now address four main themes: efficient use of raw materials, energy efficiency, emissions reduction, and process operations. This article ends by describing some of the issues with industrial applications and describes some very successful case studies before considering some of the future developments that can be expected.
