Offshore wind energy - potential for India
This paper attempts to analyze energy demand scenario, especially that of almost unlimited wind energy and highlight vast potential of offshore wind energy for India in territorial water along its long coastline. Challenges to exploit this potential, financial viability of such offshore energy projects, social, environmental, and other related issues are discussed in Indian context to serve as a useful tool for policymakers to allocate resources for detailed studies for estimation and its ultimate utilization to add to growing pool of renewable energy.
Main Challenges for Designing a Off-Shore a Wind Farm in Mexico
This article describes the main challenges involved for designing and planning of an offshore wind farm in Mexico. First, a brief description of the site is made and analysis of the wind resource is made in a maritime location located in the municipality of Magallanes, Tabasco, which has high wind potential. Subsequently, based on the characterization of the wind data, the type and class of the wind turbine is determined based on the characterization of the wind data. Then, the optimal distribution of the wind turbines is determined and the annual energy production and the losses caused by the wake effect are estimated. Also, the main components of the off-shore wind farm infrastructure are described and a parametric study is carried out to estimate the Joule losses of submarine cables. Finally, an economic viability study of the off-shore wind farm is made and a comparison is made with an on-shore wind farm.
Techno-economic analysis of chemical looping combustion with humid air turbine power cycle
Abstract Power generation from fossil fuel-fired power plant is the largest single source of CO2 emission. CO2 emission contributes to climate change. On the other hand, renewable energy is hindered by complex constraints in dealing with large scale application and high price. Power generation from fossil fuels with CO2 capture is therefore necessary to meet the increasing energy demand, and reduce the emission of CO2. This paper presents a process simulation and economic analysis of the chemical looping combustion (CLC) integrated with humid air turbine (HAT) cycle for natural gas-fired power plant with CO2 capture. The study shows that the CLC–HAT including CO2 capture has a thermal efficiency of 57% at oxidizing temperature of 1200 °C and reducer inlet temperature of 530 °C. The economic evaluation shows that the 50 MWth plant with a projected lifetime of 30 years will have a payback period of 7 years and 6 years for conventional HAT and CLC–HAT cycles respectively. The analysis indicates that CLC–HAT process has a high potential to be commercialised.
