  • Exergy analysis of a combined fuel cell and Gas Turbine Power Plant with intercooling and reheating

    This paper presents a comparative exergy study of the performance of various gas turbine power generation plants and a high temperature Solid Oxide Fuel Cell (SOFC). The overall system is analysed and its exergy efficiency and exergy destruction are obtained, as well as individual models of each component. The results for selected operating conditions are compared against past literature data. ...

  • Full-energy-chain greenhouse-gas emissions: a comparison between nuclear power, hydropower, solar power and wind power

    Fair comparison of the climate impacts from different energy sources can be made only by accounting for the emissions of all relevant greenhouse gases (GHGs) from the full energy chain (FENCH) of the energy sources. FENCH-GHG emission factors of most of the non-fossil fuel energies are lower than those of the fossil fuels that are in the range of 500-1200 g CO2/kW h(e). The improvement ...

  • Innovation risk slows offshore wind foundation development

    As offshore wind technology develops ever more gigantic machines further from shore into deeper waters, it is common wisdom that new foundation technologies are needed. But are they? Monopile, and some jacket foundations, still dominate the offshore wind market in commercial operation. Prototype floating foundations are performing well in demo or pilot projects, but scaling up is only ...

  • Symphony Of The Microgrid At An Urban University

  • Offshore Wind Versus Solar in the Eastern US: An Unexpected Rivalry

    Less than a decade ago, offshore wind energy and solar PV were similarly priced energy sources. Unsubsidized installed costs for both exceeded $5 per watt, or more than double that for land-based wind. Despite their cost, both technologies were seen as the best hopes for supplying urban centers with green power, especially in the BOSNYWASH (Boston-New York-Washington, DC) corridor of the eastern ...
