Meeting industrial heating demand through solar

Meeting industrial heating demand through solar

The International Energy Agency (IEA) estimates are that as much as 30% of the energy consumed around the world each year is in the industrial sector. 
 
Process heating - - the heat needed to produce basic materials and commodities – based on fossil fuels,is responsible for a major part of this usage and the high temperatures required are challenging to achieve most renewable energy solutions.
 
Now Clique Developments Ltd, based in Mumbai,India, have come up with a solution so innovative that the company has been named as one of five WWF Climate Solvers awarded in New Dehli on August 1.
 
“As much as 57% of industrial processes need heat of up to 4000D. Paranjape, Managing Director of Clique Developments. “We have developed an innovativesolar boiler system which we have named ARUN®to cater to this thermal energy need.”
 
ARUN® technology is based on the basic principles ofa magnifying glass and a sunflower. A magnifying glass concentrates sunlight at a single point with the help of parabolic lenses. Similarly, ARUN uses an ingenious, fresnelized mirror arrangement scheme to get a 3-dimensional parabola effect. Like a sunflower, ARUN automatically tracks the sun from sunrise to sunset on both East-West and North-South axes to intercept maximum sunlight throughout the year, irrespective of the installation location. ARUN dish is mounted on a single column, thus occupying ground area of less than 3m x 3m.
 
The receiver is designed to operate at temperatures of up to 3000 pressures of up to 20 bar. The system works as a solar boiler, substituting the consumption 
of conventional fuels such as Furnace Oil, High Speed Diesel (HSD), Piped Natural Gas (PNG) and coal for example in dairy, automobile and chemical industries.
 
The ARUN® dish with its innovative solar concentrating technology can significantly reduce dependence of industrial and commercial sector on traditional fossil fuels for thermal energy needs. Assuming wider global deployment, this technology has a potential to avoid28 million tons of GHG emissions by 2023.

What constitutes your major barrier for even faster growth in the future?
 
The main barrier is the lack of awareness amongst potential end users about the use of solar for mid to high temperature thermal energy needs. Similar to how it promoted the solar PV sector, the government can give a push to this sector by creating market demand in the various government owned companies, institutions, etc and enabling a number of reference projects. This will help create the necessary awareness, reduce the perceived technology risk and give confidence to the private industries to invest in such projects in a big way.
