Assessment of CO₂ emanation in a solar steam cooking plant in Himalayan region: With and without preheated water Available to Purchase

A study on the reduction of CO₂ emission from a 500 persons’ solar steam cooking plant fixed on girl’s hostel of Shoolini University, Solan (HP) has been performed and noticed that one commercial LPG cylinder has been saved on daily basis reducing 17,217.42 kg of CO₂ emission per year. According to UNCDM, it will earn 17.2 carbon credits for the University. Further to increase the performance of the plant, preheated water from flat plate collector was supplied to the plant. This enabled steam formation inside heat pipe one hour prior to normal winter days’ hours. 500 L of hot water was additionally supplied to curb jaundice outbreak. Use of preheated water for steam generation saved another half commercial LPG cylinder, which in turn has reduced 8,608.71 kg of CO₂ emission, earning 8.6 more carbon credits. The total reduction in CO₂ emission has been found 25,826.13 kg per year and earnings of 25.8 carbon credits to the University. These earned carbon credits may be redeemed as per global carbon credit rules.
