Carbon credit earned by some designs of solar stills

Abstract

This paper presents the theoretical analysis of CO₂ emission/mitigation and carbon credit earned by different designs of solar still in India. Numerical computation is performed on the basis of experimental performance of the solar stills, reported by various researchers. Estimation of carbon credits, which will accrue to the nation, is carried out for an expected system life span of 20 years and accounting 250, 275, and 300 clear days during a year. Return on the investment on the basis of life cycle cost analysis has also been carried out accounting carbon trading in the European market. It is found that the annual cash flow due to the carbon trading decrease the cost of production of distillate by Rs. 0.15 per liter with current carbon trading rate €2.10 per ton.
