Cover Story: Net Zero UK showed that the UK could really become carbon neutral, and as a direct result, benefit from reduced energy costs. Using biomethane for energy storage, a dynamic model showed how the zero-carbon grid could be balanced every day for the last five years of weather data. View this paper.

Traffic NOx Pollution Prediction and Health Cost Estimation Using Machine Learning: A Case Study of Toronto, Canada

Received: 11 March 2022;  Published: 25 December 2022;  doi: 10.21926/jept.2204043

Abstract

Road traffic is a significant source of air pollution that has a harmful impact on human health. To reduce the health and environmental impacts of fossil fuel consumption in the transportation sector, many countries have implemented policies to promote the deployment of electric vehicles (EVs). A vital factor to consider when designing policies to support EV use is the monetized health impacts of fossil fuel consumption. This research aims to investigate the health benefit of replacing internal [...]

Evaluation of Oxidative Stability and Kinetic Parameters of the Cottonseed and Soybean Biodiesels by Rancimat and Differential Scanning Calorimetry Techniques

Received: 26 September 2022;  Published: 22 December 2022;  doi: 10.21926/jept.2204042

Abstract

In this study, the oxidative stability of the cottonseed oil biodiesel (CB) and soybean oil biodiesel (SB) was investigated by two methodologies, Rancimat and Differential Scanning Calorimetry (DSC), using samples fresh and aged (mid-term storage condition (100 days)). The biodiesel samples were synthesized by transesterification and characterized by specific mass, kinematic viscosity, acidity value, ester content, viscosity index, and peroxide value. The activation energy (E

Net Zero UK – Generation and Energy Storage Requirements for the UK to Become Carbon Neutral

Received: 25 September 2022;  Published: 13 December 2022;  doi: 10.21926/jept.2204041

Abstract

This paper sets out a quantified scenario for the UK to reach net zero carbon emissions. Wind and solar are the main energy sources and their intermittency is accommodated through hydrogen electrolysis, biogas from anaerobic digesters, and their combination into biomethane. Hydrogen and biomethane stocks are tracked. A daily energy balance model is presented, using the most recent recorded weather data-2017 to 2021. Long periods of low wind in 2021 indicated the necessary energy stor [...]

Enhancing the Wettability of Polyetheretherketone (Peek) Membrane with Ozone for Improving Fuel Cell Performance

Received: 21 August 2022;  Published: 06 December 2022;  doi: 10.21926/jept.2204040

Abstract

Ozone was reacted with the aromatic membrane polyetheretherketone (PEEK) to form oxidized functional groups on the surface to enhance the attraction and transport of protons in fuel cells. Ozonation of unsaturated C-C sp2 bonds in PEEK formed a primary ozonide which dissociated to primarily produce O=C-O/O=C-OH moieties, and the root mean squared roughness factor (Rq) decreased from 7.4 nm, for the untreated sample, down to 3.1 nm. The oxidation of t [...]

The Design, Development and Assessment of a Novel De-centralised IoT-Based Remote Monitoring of a Small-Scale Anaerobic Digester Network

Received: 21 September 2022;  Published: 28 November 2022;  doi: 10.21926/jept.2204039

Abstract

The implementation of community-level de-centralised anaerobic digestion (AD) systems offers a sustainable solution for organic waste management and energy provision, but there is currently a need for low-cost methods of system control and management at this scale. The problem becomes accentuated with increasing deployment, as greater complexities are created by the need to both monitor and control a wider network of smaller, community-scale plants. This paper describes research to design, deplo [...]

Fabrication of Perovskite Solar Cells by the Smart Stacking Process

Received: 21 September 2022;  Published: 25 November 2022;  doi: 10.21926/jept.2204038

Abstract

The most commonly used process for fabricating perovskite solar cells is based on wet chemistry, which greatly limits the choice of materials suitable for optimizing the performance of the device. We developed a new approach for the fabrication of perovskite-based solar cells. In the smart stacking process, the perovskite solar cell was assembled by stacking two pieces of perovskite films prepared separately. A working perovskite solar cell was developed with PCE = 0.78% and the perovskite layer [...]

The Impacts of Offshore Wind Farms (OWFs) on Local Tourism and Recreation -- Evolving Lessons from Practice

Received: 06 July 2022;  Published: 16 November 2022;  doi: 10.21926/jept.2204037

Abstract

The article examines the nature of impacts of the rapidly growing Offshore Wind Farm (OWF) industry on tourism and recreation in coastal communities, especially in the UK. The multi-methods research approach includes reviews of literature, content of OWF Environmental Statements (ESs) for predicted impacts, recent practice for actual impacts, and the use of mitigation and enhancement measures. Findings from literature indicate that the overall impact on tourism appears relatively benign, and som [...]

A Data-Based Reliability Analysis of ESP Failures in Oil Production Wells

Received: 27 September 2022;  Published: 14 November 2022;  doi: 10.21926/jept.2204036

Abstract

Electrical Submersible Pumps (ESPs) are one of the most widely used artificial lift methods in the petroleum industry. However, ESP failures are unanticipated and common occurrences with significant financial impacts for the operators. Analysis of the ESP performance and failures are essential in its design and optimization. This paper presents a statistical approach for diagnosing and evaluating the root causes of ESP failures. The analysis is based on the field data gathered from the surface a [...]

Comparing Environmental Impacts Arising from the Use of Electric Two-Wheeler vis-a-vis Gasoline Two-Wheeler in India

Received: 26 July 2022;  Published: 09 November 2022;  doi: 10.21926/jept.2204035

Abstract

Electric vehicles are becoming popular among consumers while BS-VI norms have been introduced and mandated for conventional vehicles in India. In the present study, the environmental impacts from the use phase of electric two-wheeler (EV) and gasoline two-wheeler (GV) have been evaluated and compared using the life cycle assessment (LCA) perspective. The functional unit adopted was 1000 km driven by one vehicle under Indian road and traffic conditions. CML 2001 and ReCiPe 2016 method [...]

A Dual-PRF Scan Mode and Adaptive Doppler-Velocity Dealiasing to Increase Radar Clear-Air Velocity Data Coverage and Usability

Received: 05 August 2022;  Published: 13 October 2022;  doi: 10.21926/jept.2204034

Abstract

By using long pulses with extended dwelling time, lowered pulse repetition frequency (PRF) and reduced Nyquist velocity, the radar measurement capability can be enhanced to increase clear-air Doppler velocity data coverage (which is beneficial for radar wind analysis and data assimilation and motivated our previous study). This potential capability is further explored (beyond our previous study) by not only modifying the existing operational clear-air scan mode with a lowered PRF and reduced the [...]

The Physical Potential for Dutch Offshore Wind Energy

Received: 04 August 2022;  Published: 10 October 2022;  doi: 10.21926/jept.2204032

Abstract

In the Netherlands, an important way to contribute toward achieving climate goals is the large-scale deployment of wind turbines in the North Sea. The North Sea is a unique location for offshore wind power thanks to its strong winds, shallow waters, and proximity to large energy users. Wind turbines generate electricity by extracting kinetic energy from the atmosphere. This kinetic energy is replenished at a finite rate through the mixing of atmospheric layer [...]

A Robust Second-Order Conic Programming Model with Effective Budget of Uncertainty in the Optimal Power Flow Problem

Received: 29 December 2021;  Published: 09 October 2022;  doi: 10.21926/jept.2204031

Abstract

Integrating large-scale wind energy in modern power systems necessitates high-efficiency mathematical models to address classical assumptions in power systems. In particular, two main assumptions for wind energy integration in power systems have not been adequately studied. First, nonlinear AC power flow equations have been linearized in most of the literature. Such simplifications can lead to inaccurate power flow calculations and result in technical issues. Second, wind power uncertainties are [...]
