| Abstract | The proposed novel compressed air energy storage (CAES) concept is based on the utilization of capacity reserves of combustion turbine (CT) and combined cycle (CC) plants for the peak power generation, instead of development of highly customized and expensive turbo-machinery trains. These power reserves are particularly high during high ambient temperatures that correspond to typical summer peak power requirements. The stored compressed air will be injected into the CT after the compressor diffuser to supplement the reduced (due to high ambient temperature or altitudes) mass flow, through the turbine to the full potential (typically achieved at low ambient temperatures). The alternative concept, with stored compressed air, is humidification before injection into the CT, this reduces the auxiliary compressor size, the storage volume and associated costs. Power increase of up to 25% can be realized, coincidental with that which is typical for a CAES plant, significant reduction in the heat rate and emissions. The novel CAES concept reduces specific plant costs by a factor of two, which makes it particularly effective for integration with renewable energy sources, like wind energy plants and landfill gas (LFG) plants. The paper also presents an alternative small capacity CAES plant, which is based on using smaller man-made storage facilities (high pressure pipes and/or vessels), either underground or above ground that can be readily constructed at CT sites without specific geological requirements. The latter part of this paper specifically concentrates on integration of CAES with wind and landfill gas (LFG) plants. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
