Alkaline water electrolysis (AWE) is a mature hydrogen production technology and there exists a range of economic assessments for available technologies. For advanced AWEs, which may be based on novel polymer-based membrane concepts, it is of prime importance that development comes along with new configurations and technical and economic key process parameters for AWE that might be of interest ...

steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...

Low-grade heat sources such as solar thermal, geothermal, exhaust gases and industrial waste heat are suitable alternatives for power generation which can be exploited by means of small-scale Organic Rankine Cycle (ORC). This paper combines thermodynamic optimization and economic analysis to assess the performance of single and dual pressure ORC operating with different organic fluids and targe...

The current key challenge in the floating offshore wind turbine industry and research is on designing economic floating systems that can compete with fixed-bottom offshore turbines in terms of levelized cost of energy. The preliminary platform design, as well as early experimental design assessments, are critical elements in the overall design process. In this contribution, a brief review of cu...

This paper presents the development of a framework used to optimize and experimentally validate a novel axial flux direct-drive (DD) permanent magnet generator (PMG) for the offshore wind turbine market. This technology aims to offer significant levelized cost of energy (LCoE) reductions via capital expenditure and operating expense (CAPEX and OPEX) savings – a key objective for the offshore in...

In order to understand the economic feasibility of an offshore wind farm, this paper analyzed differences in LCOE (levelized cost energy) according support type and construction method substructure terms sensitivity analysis was conducted main components LCOE. As for site be studied, Southwest Offshore Wind Farm selected, capital expenditures were calculated size farm installation unit. a resul...
