1 SUMMARY This study investigates the potential for the large-scale roll-out and implementation of solar thermal (ST) technologies in South African hospitals to offset conventional fuel use and identifies challenges relating to this potential uptake. There are a total of 696 hospitals in South Africa (SA) with a total thermal energy demand for 20 hot water of 370 GWh per year. A total installed collector area of 73 972 m2 to 147 944 m2 across all hospitals in SA would increase the overall ST capacity of all these hospitals to compensate for 20 to 40% of their combined annual thermal energy demand. The major limiting factor for the uptake of ST technologies in South African hospitals is the current wide spread use of coal fired boilers as well as heat-pumps, making the adoption of ST technologies less feasible from a financial perspective. 25

In this paper, heat integration for a dairy factory is performed using two different approaches with storage integration capabilities. The use-case consists of 36 process streams which can be considered large-scale. Stream data is available for a period of three weeks with high temporal resolution. Even though a slightly different data basis is needed, both approaches yield comparable results which are analyzed in this paper. The first approach considered in this work is the software tool SOCO which is based on pinch-analysis for time-dependent process streams. It incorporates a flowsheet simulation environment for detailed storage simulation. The second approach is based on mathematical programming and cost-driven superstructure optimization using simple storage models. The best results obtained using both approaches are compared regarding heat exchanger networks, storage integration and economic data. Also, potential synergies between the two approaches are identified that could further improve solutions.

An approach for estimating national targets for industrial excess heat recovery based on detailed analysis of data from case studies followed by regression analysis is proposed and applied to the Kraft pulping industry in Sweden. According to the resulting estimates, there is a large potential for increasing the excess heat utilization from the Swedish pulp and paper mills. The suggested methodology provides a more detailed picture of industrial excess heat availability in the Swedish pulp and paper industry and could be applied to other sectors and regions.
