Only about 200 solar thermal plants are installed worldwide at industrialsites, with a total installed capacity of 42 MW th (60,000 m 2 ), even though this applicationhas a huge technical and commercial potential. The industrial heat demand, including processheat, space heating, and hot water accounts for 75% of industry’s final energy consumption.Much of the heat demand below 100°C could theoretically be met with solar thermalsystems using current technologies, if suitable integration of the solar thermal systemcan be identified. With technological development, more and more high temperatureapplications between 250°C and 400°C will also become commercially feasible.In several specific industry sectors, such as food, wine and beverages, transportequipment, machinery, textiles, pulp and paper, the share of heat demand at low andmedium temperatures is around 60% (POSHIP 2001). Solar thermal could contribute here.Due to their size and because they must be adapted to each specific application, large-scalesystems for industrial process heat are custom-designed. Small-scale systemscan be pre-fabricated to a greater extent.58Ecoheatcool (2006).52
RenewableHeating & CoolingEuropean Technology Platform5.2.1 Research and innovation priorities with impact in the Short TermST.10ObjectiveMedium temperature collectors developed and demonstrated in industrial applicationsUsing solar thermal collectors in medium and high temperature (100°C–400°C) systemsimposes constraints on collectors.Applied research should result in the development of new, high temperature-resistantmaterials, as well as new collector designs. the following aspects are particularly important :• Adapting and improving collector technology (flat-plate and evacuated tube) whichis currently used in low-temperature applications (e.g. either through better insulationor noble gas atmospheres); or,• Developing specific concentrating collectors using light-weight, stable, highly performingand dirt-proof or self-cleaning reflectors which are resistant to degradation due to mechanicalcleaning and weathering.Moreover, cost-effective fixing systems are needed for specific installation and maintenancerequirements of large-scale applications.State-of-the-artTargetsType of activityPilot solar systems used for industrial process heat are available in Europe. Many systems forindustrial heat are configured to work at higher temperatures than the process would require.Today, arrays of flat plate collectors constitute the majority of the installed capacity due to cost,reliability and modularity reasons. However the use is limited to low temperature processes.50% cost reduction on installed collector with increased reliability (lower O&M costs).10% Research / 50% Development / 40% Demonstration5.2.2 Research and innovation priorities with impact in the Medium and Long TermTurn-key solar thermal process heat systems (ST.11). R&D is needed to analyse andoptimise medium and high temperature industrial processes to allow new applicationsof solar thermal technology. Innovative schemes should be investigated for the integrationof steam generated by medium-temperature collectors in the production process and distributionnetwork.ST.10Research and Innovation PrioritiesOptimize large-scale solar collector arrays for uniform flow distributionand low pumping powerPredominanttype of activityImpactDevelopment By 2020ST.11 Turn-key solar thermal process heat systems Research By 2030Table 11: research and innovation priorities for solar thermal applications to industrial processes5.3 Biomass technologyBioenergy co-generation (CHP) as well as tri-generation (heat-power-cold) are interestingconcepts to supply direct renewable heat to most industrial processes. Unit costs of bioenergyplants are inversely related with system’s size (Figure 33), so larger systems whichtypically supply their energy to singular industrial heat consumers are generally more costefficientthan small ones.Biomass plays a specific role among RES as storable energy source. Bioenergy thereforepresents a real advantage when considering its integration in the overall renewable energysystem. Besides the production of heating and cooling, CHP (combined heat and power) andtri-generation or CHP-C (combined heat, power and cooling) technologies are ableto supply intermittent electricity, balancing both daily and seasonal changes in solar and windelectricity production.59Biomass input = 80 MW th,same boundary conditions forall conversion technologies.FBC: fluidized bed combustion,IGCC: integratedgasification combined cycle,D.comb: Direct Co-Combustionwith Coal, Ind.comb:Indirect Co-Combustion withCoal.
