CO₂ Emissions Mitigation Potential of Some Renewable Energy Technologies in India

Abstract

An attempt to develop simple frameworks for quantification of the CO₂ emissions mitigation potential of renewable energy technologies for domestic water heating, domestic lighting, water pumping, and crop drying has been made. The annual useful energy provided by each of the renewable energy technology and the annual saving of fuel/electricity have been estimated. The gross annual amount of CO₂ emissions mitigation, as well as net amount of annual CO₂ emissions mitigation potential of each technology, is estimated by taking into account the CO₂ emissions embodied in the device.

Keywords:

Notes

^a Design parameters: AV-45 (A = 15.9 m², v _ci = 1.80 m/s, v _r = 2.80 m/s, v _co = 10.00 m/s); AV-55 (A = 23.8 m², v _ci = 1.50 m/s, v _r = 3.00 m/s, v _co = 10.00 m/s); GM-II (A = 7.1 m², v _ci = 2.22 m/s, v _r = 5.55 m/s, v _co = 23.89 m/s); SICO (A = 7.1 m², v _ci = 2.22 m/s, v _r = 3.33 m/s, v _co = 13.89 m/s).

^a Thermal efficiency of coal based traditional tobacco curing barn is 0.19 (Bhattacharya et al., 1999) and for small cardamom it is 0.06 (Rao et al., 2001).

^b SCM: standard cubic meters (defined as heating value of one SCM natural gas is 10000 kcal).
