Combined cooling, heating, and power (CCHP) or trigeneration technology: An approach toward higher energy efficiency, emission reduction potential and policy

Abstract

The energy demand in India is growing at a very fast rate, the present energy generation could not be able to keep pace with this increasing demand with energy shortage of 6.2 % and peak shortage of 2.3 %. To address the increasing gap between demand and supply, there is an urgent need to bridge the gap through energy efficiency and integration of renewable energy in the energy mix of the country. This paper presents a new concept in Indian building sector which addresses the energy efficiency through Trigeneration technology. A gas engine with natural gas is used to produce power, and the waste heat for producing cooling and heating through Vapor Absorption Machine (VAM) and hot water recovery from low temperature (LT) jacket water respectively. This increases the efficiency up to 85 % or even more as compared to the conventional methods of power production. The present paper discusses one such case study on a pilot project implemented under the Indo-German Energy Program. The pilot project is funded by the German Federal Ministry of Environment, Nature Conservation, Building and Nuclear Safety (BMUB) and is the first project completed successfully under International Climate Initiative (IKI) of BMUB in India. This paper presents the information on the techno-economics of the pilot project at New Delhi.
