Computational Micromechanics for the Optimization of Compression Strength of Unidirectional Carbon Fiber Composites for Use in Wind Turbine Blades

Received: 15 April 2020;  Published: 09 June 2020;  doi: 10.21926/jept.2002010

Abstract

As wind turbine blades grow longer, new design parameters gain additional importance such as blade weight, tip deflection and material cost. These parameters require designers to relook at carbon fiber as a potential design solution. However, the composite materials in wind turbine blades are subjec [...]

Using Additives to Control the Decomposition Temperature of Sodium Borohydride

Received: 20 April 2020;  Published: 19 May 2020;  doi: 10.21926/jept.2002009

Abstract

Hydrogen (H2) shows great promise as zero-carbon emission fuel, but there are several challenges to overcome in regards to storage and transportation to make it a more universal energy solution. Gaseous hydrogen requires high pressures and large volume tanks while storage of l [...]

The Impact of Operating Conditions on the Performance of a CH4 Dry Reforming Membrane Reactor for H2 Production

Received: 25 March 2020;  Published: 14 May 2020;  doi: 10.21926/jept.2002008

Abstract

Biogas is a promising resource for the production of H2 since it liberates energy by recycling waste, along with the reduction of CO2. In this paper, the biogas dry reforming membrane reactor is proposed to produce H2 for use in fu [...]

Hierarchically-Structured Ti/TiO2 Electrode for Hydrogen Evolution Synthesized via 3D Printing and Anodization

Received: 09 April 2020;  Published: 09 May 2020;  doi: 10.21926/jept.2002007

Abstract

Hierarchically-structured, electro-catalysts consisting of a titanium core with controlled macro-porosity and a thin titania surface-layer with controlled nano-porosity were synthesized via combination of additive manufacturing and in-situ anodization. The electrodes were tested for hydrogen evoluti [...]

Assessment of Stability-Based Characterizations of North Carolina’s Offshore Wind Resource Using a Nested Boundary Layer Method

Received: 10 April 2020;  Published: 30 April 2020;  doi: 10.21926/jept.2002006

Abstract

SODAR wind profiler measurements from a land-based site within 1000 m of the coastal ocean are compared with predicted wind profiles based on upwind conditions and a stability-based model. The thermally dynamic influence of the Gulf Stream near the site of measurement, Cape Hatteras, has [...]

Storable Energy Production from Wind over Water

Received: 28 January 2020;  Published: 29 April 2020;  doi: 10.21926/jept.2002005

Abstract

The current status of a project is described which aims to demonstrate the technical and economic feasibility of converting the vast wind energy available over the globe’s oceans and lakes into storable energy. To this end, autonomous high-performance sailing ships are equipped with hydrokinetic tur [...]

Autonomous Hydrogen Production for Proton Exchange Membrane Fuel Cells PEMFC

Received: 04 March 2020;  Published: 28 April 2020;  doi: 10.21926/jept.2002004

Abstract

This paper focuses on hydrogen production for green mobility applications (other applications are currently under investigation). Firstly, a brief state of the art of hydrogen generation by hydrolysis with magnesium is shown. The hydrolysis performance of Magnesium powder ball–milled along with diff [...]

Water Photo-Oxidation Reaction on Clean and Doped Two-Dimensional Graphitic C2N

Received: 16 February 2020;  Published: 20 April 2020;  doi: 10.21926/jept.2002003

Abstract

In the search for new efficient photo-catalysts for hydrogen production through water splitting, the main attention has been paid to tuning the band gap width and its position with respect to vacuum level. However, actual electro-catalytic activity for the water oxidation reaction on a catalyst surf [...]
