Testing the Correlation between Prior Knowledge of - and Visualisation Guided WTPs for Reducing the Visual Impacts Visual from Offshore Wind Farms

Received: 28 April 2020;  Published: 12 August 2020;  doi: 10.21926/jept.2003015

Abstract

Visual external costs are significant elements in the cost-benefit analysis of wind farm locations. This has been demonstrated well in the literature. However, in the assessment of the visual costs, a large share of the earlier studies used no or only simplistic visualizations of the visual impacts [...]

Grid Integration of a Residential PV-based Hybrid Renewable Energy System Using High-Frequency Multi-winding Transformer

Received: 13 June 2020;  Published: 05 August 2020;  doi: 10.21926/jept.2003014

Abstract

In this paper, a topology of a residential hybrid renewable energy system based on a high-frequency multi-winding transformer is introduced and analyzed. The system includes a PV and a wind-turbine as renewable energy sources, a battery as energy storage and their energies are integrated through a h [...]

Sustainability Implications of Using Hydrogen as an Automotive Fuel in Western Australia

Received: 29 June 2020;  Published: 31 July 2020;  doi: 10.21926/jept.2003013

Abstract

Hydrogen is regarded as a potential solution to address future energy demands and environmental protection challenges. This study assesses the triple bottom line (TBL) sustainability performance of hydrogen as an automotive fuel for Western Australia (WA) using a life cycle approach. Hydrogen is con [...]

Seismic Imaging of Convective Geothermal Flow Systems to Increase Well Productivity

Received: 03 December 2019;  Published: 29 July 2020;  doi: 10.21926/jept.2003012

Abstract

A core feature of convective geothermal resource production is wellbore energy flow Q ~ ρC x T x V. E.g., for wellbore fluid of volume heat capacity ρC ~ 4.3MJ/m3oC, temperature T ~ 230oC, and volumetric flow V ~ 50L/s, wellbore h [...]

A Simplified Optimization Model for Sizing Proton-Exchange Membrane Fuel Cells

Received: 03 June 2020;  Published: 24 July 2020;  doi: 10.21926/jept.2003011

Abstract

The fluctuations in the cost of energy coupled with the gradual decrease in natural resources (i.e., oil, natural gas, coal) and the environmental issues caused by the extensive use of fossil fuels, demand the urgent need for the development of advanced and clean energy systems. The European Union h [...]
