The CO2 mitigation and Exergo- and Environ- economics analysis of
Bio-gas integrated Semi-transparent Photo-voltaic Thermal (Bi-iSPVT)
system for Indian composite climate
Abstract
It is to be noted that bio-gas production is drastically reduced in cold
climatic condition especially in winter due to drop in ambient air
temperature which is much below optimum temperature of about 37 for
fermentation of slurry. Many methods namely hot charging, passive/active
for slurry heating has been tested and it has been found that the
passive heating method is neither practical nor self-sustained. In order
to make bio-gas heating with self-sustained, economical and friendly
with an ecology and environment, new approach of Bi-iSPVT, has been
adopted. Based on the finding, we have made an attempt to analyze the
system in terms of CO2 mitigation, energy matrices and environ- and
exergo-economics to have clean environment and sustainable climate. The
analysis has been done by using embodied energy, annual overall thermal
exergy of the system for ecological balance for good health of human
being. It has been found that an energy payback time (EPBT) for
sustainable Bi-iSPVT system is about 1.67years along with an
exergo-economic parameter (Rex) of 0.1016 kWh/₹.
