Fuel Storage

In the present work, Hybrid fuel storage system of compressed air is an extensive technology that provides long duration energy storage. It is encouraged in balancing the large scale penetration of intermittent and dispersed sources of power. Such as wind and solar power into electric grids .The existing Compressed air energy storage (CAES) plants utilize natural gas as fuel. In this project we are replacing the natural gas with the composition of air (15 bar), copper oxide (5-20%), and water (50%). validated with the results obtained using Computational Fluid Dynamics (CFD) analysis. Modeling of energy storage tank is done in Computer Aided Three Dimensional Interactive Application (CATIA) software, mesh has been created using ANSYS workbench software and Analysis is done in Fluent Software. The composition is sent from the inlet of the energy storage tank and temperatures are varied like 298k, 373k, 423k, and 473k. Velocities are also varied like 15m/s, 25m/s, 35m/s, 45m/s. This hybrid fuel storage deals with phase change material by using water and copper by heating at different temperatures to get the energy and re-utilized. This device is applicable for renewable energy application to avoid the heat losses new technique of energy saving in suitable forms. This has the lead to the emergence of fuel storage as a management of energy and allowing it to various levels of energy storage. In many parts of the world this storage of energy plays an important role and a new technique of energy saving in suitable forms. This has the lead to the emergence of fuel storage as a management of energy and allowing it to various levels of energy storage.

Compressed Air Energy Storage

Non-renewable energy sources such as coal, oil, and natural gas are being consumed at a brisk pace while greenhouse gases contribute to atmospheric pollution. A global shift is underway toward the inclusion of renewable energy sources, such as solar and wind, for generating electrical and mechanical power. To meet this emerging demand, a solar based electrical microgrid study is underway at Clemson University. Solar energy is harvested from photovoltaic panels capable of producing 15 kW of DC power. Compressed air energy storage has been evaluated using the generated solar power to operate an electric motor driven piston compressor. The compressed air is then stored under pressure and supplied to a natural gas driven Capstone C30 MicroTurbine with attached electric power generator. The compressed air facilitates the turbine’s rotor-blade operated compression stage resulting in direct energy savings. A series of mathematical models have been developed. To evaluate the feasibility and energy efficiency improvements, the experimental and simulation results indicated that 127.8 watts of peak power was delivered at 17.5 Volts and 7.3 Amps from each solar panel. The average power generation over a 24-hour time period from 115 panels was 15 kW DC or 6 kW of AC power at 208/240 VAC and 25 Amps from the inverter. This electrical power could run a 5.2 kW reciprocating compressor for approximately 5 hours storing 1,108 kg of air at a 1.2 MPa pressure. A case study indicated that the microturbine, when operated without compressed air storage, consumed 11.2 kg of gaseous propane for 30 kW·hr of energy generation. In contrast, the microturbine operated in conjunction with solar supplied air storage could generate 50.8 kW·hr of electrical energy for a similar amount of fuel consumption. The study indicated an 8.1% efficiency improvement in energy generated by the system which utilized compressed air energy storage over the traditional approach.
