CST Process Heat Solution for India’s Top Cancer Hospital With ANU’s BigDish

Study of Solar Thermal Powered Tri-Generation System

Abstract

India has an abundance of solar radiation, making Concentrated Solar Thermal Technologies an economical option to complement, if not replace, fossil fuels for various Industrial Applications. Some of the most viable applications are space and water heating/cooling, process heat, water desalination and effluent treatment. When hybridised with biofuels these thermal energy solutions can deliver 24 x 365 renewable energy.

India has great potential for solar industrial process heating and cooling. Recent studies have shown an addressable market potential of 6.5 GW-thermal for CST technologies out of a total of 13 GW thermal technical potential for industrial applications requiring heat of temperature up to 300°C[1]. Higher temperature applications in industry sectors such as cement, steel and chemical production add further to this potential.

Sunrise CSP’s Big Dish solar concentrator, developed in collaboration with the Australian National University, is a modular 400kWthermal CST platform capable of delivering the steam requirements for the industry at temperatures currently ranging from 150°C to 600°C and pressures up to 160 bar, with new heat transfer fluids lifting temperatures to 800°C planned. The Big Dish is specifically designed for local manufacture and its modularity supports staged and scalable solar field deployment that enables socio-economically appropriate solutions spanning factory-scale to national utility-scale with a Levelized Cost of Steam (LCoS) 14% - 25% lower than fossil fuel alternatives in India.
