Process heat in Jordan Christian Zahler, Industrial Solar GmbH 22 March 2017, Berlin

1. Status Quo – Market EU Almost 50% is for heating and cooling

How to reduce fossil fuel consumption for process heat? Challenge of the Century How to reduce fossil fuel consumption for process heat? Biomass Very limited potential, especially in arid areas / ecologically critical / competing with food production Heat pumps (possibly combined with PV) Currently thermodynamically inefficient at higher temperatures but upcoming new generation of high temperature heat pumps Waste heat (e.g. from CHP) Generally available at lower temperature levels Conventional solar collectors Can deliver heat of up to 130 °C, but might be replaced through waste heat, if available Concentrating solar collectors Can deliver heat up to 400 °C

Steam Storage Concept Ruth storage used for steam accumulation Several functions Steam accumulation Pressurization Expansion vessel Separation of steam from condensate

Operation Diagramm Data Center Fluctuating Pressure in Drum Fluctuating DNI Fluctuating Pressure in Drum Very stable pressure in steam network due to solar generated steam Without irradiation the fossil boiler provides steam T collector out determined by steam drum pressure Steam valve opening controls pressure in steam network

Steam valve opening controls pressure in steam network Measurement – 13th May, 2015 Steam valve opening controls pressure in steam network Steam drum compensates fluctuations in load profile as well as in irradiation When not all of the potential steam is needed, some of the mirrors are turned out of focus

Conclusion Technical System delivers expected performance Steam drum useful for stable steam supply Effects of steam drum by-pass to be investigated Project Local partner very important (transport, local workforce & communication) Co-funding by GIZ was helpful to achieve acceptable payback-time of rather small system size Customs and transport are always a challenge Market Industrial Solar received requests over the last years of 1.900 MWth and commissioned various systems all over the world with different partners Sustainability becomes more and more part of shareholder value management Payback-time expectations moves from 2-3 years to 4-7 years > Solar process heat gains more and more momentum
