Co-development of Low-speed Electric Community Buses for Local Area Revitalization

Received: 10 October 2022;  Published: 02 February 2023;  doi: 10.21926/jept.2301005

Abstract

This paper describes the development of low-speed electric community buses (LSECBs) designed by the author's group and their spread situation in Japan. LSECBs are electric vehicles that can travel on public roads at speeds of less than 5.56 m/s (20 km/h). The university, local government, local businesses, and residents with a co-design approach developed the LSECBs. They have various [...]

Green Energy Sources Reduce Carbon Footprint of Oil & Gas Industry Processes: A Review

Received: 25 September 2022;  Published: 28 January 2023;  doi: 10.21926/jept.2301004

Abstract

In recent years, the oil and gas sector has been moving towards green production methods to achieve net-zero emission goals. Governments and corporations have started large-scale initiatives to deploy advanced technologies to reduce carbon footprints and prevent global warming. Herein, we have explored the emerging techniques and methods used in reducing the effects of gas emissions in the oil and gas industry. The transition process from hydrocarbons to renewable energy resources, including sol [...]

Significance of Insulation and Heat Pumps in Decarbonising the UK

Received: 09 November 2022;  Published: 09 January 2023;  doi: 10.21926/jept.2301003

Abstract

This paper examines the economic case for the UK to proceed urgently with the installation of thermal insulation and heat pumps in most UK buildings, in the context of the legal requirement to achieve net-zero carbon emissions by 2050. A recent study by the same authors assumed that such insulation and heat pumps would be in place, and showed how the whole of the UK’s energy demand could be met by low carbon electricity generation and appropriate storage. This paper extends the model [...]

The Effect of Rotor Radius Ratio on The Performance of Hybrid Vertical Axis Wind Turbine Savonius-Darrieus NREL S809

Received: 05 October 2022;  Published: 02 January 2023;  doi: 10.21926/jept.2301001

Abstract

This research aims to know the effect of the Rotor Radius Ratio on the performance of the hybrid Vertical Axis Wind Turbine Savonius-Darrieus NREL S809 model using the Computational Fluid Dynamics method. Two-bladed Savonius is used as an internal rotor, and three-bladed Darrieus NREL S809 as an external rotor. Turbine model performance is analyzed through the value of the Moment Coefficient and Power Coefficient. The result shows that the increase in the Rotor Radius Ra [...]
