Sorption-Based Energy Storage Systems: A Review, Kyaw Thu, Nasruddin Nasruddin, Sourav Mitra, Bidyut Baran Saha Apr 2019

Sorption-Based Energy Storage Systems: A Review, Kyaw Thu, Nasruddin Nasruddin, Sourav Mitra, Bidyut Baran Saha

Makara Journal of Technology

Mismatched timing between the supply and demand of energy calls for reliable storage systems. Energy storage systems have become further significant with the widespread implementation of renewable energy. These systems can mitigate problems that are often associated with renewable energy sources such as supply unreliability while meeting the de-mand during peak hours. Energy can be stored in various forms, yet storage systems can be generally grouped based on their output forms, namely (i) electricity and (ii) heat or thermal energy. Electrical energy is the most convenient and effective form since it can power almost all modern devices. However, the electricity ...


Evaluation Of Wind And Solar Energy Investments In Texas, Byungik Chang, Ken Starcher Mar 2019

Evaluation Of Wind And Solar Energy Investments In Texas, Byungik Chang, Ken Starcher

Civil Engineering Faculty Publications

The primary objective of the project is to evaluate the benefits of wind and solar energy and determine economical investment sites for wind and solar energy in Texas with economic parameters including payback periods. A 50 kW wind turbine system and a 42 kW PV system were used to collect field data. Data analysis enabled yearly energy production and payback period of the two systems.

The average payback period of a solar PV system was found to be within a range of 2-20 years because the large range of the payback period for PV systems were heavily influenced by incentives ...


Techno- Economic Feasibility Study Of Solar Water Pumping For Public Facilities In Nigeria, Anamika Singh Jan 2019

Techno- Economic Feasibility Study Of Solar Water Pumping For Public Facilities In Nigeria, Anamika Singh

HSU theses and projects

This thesis presents a techno-economic feasibility analysis of solar water pumping systems in public facilities located in rural parts of Nigeria. Three different public facilities namely, a primary health care center in Ibwa (PHC, Ibwa), a comprehensive health care center in Kwali (CHC, Kwali), and the LEA Primary School in Mapa (LEA School, Mapa), all located in Federal Capital Territory (FCT) of Nigeria, were analyzed. The facilities considered in the study have varying levels of water demand (micro, small, and medium), and they are used as cases to establish the techno-economic suitability of solar water pumping systems to deliver water ...


The Heat Is On: The Capacities Required For The Establishment And Sustainability Of Community-Owned Renewable Energy District Heating Systems In Ireland, Gerard Doyle Jan 2019

The Heat Is On: The Capacities Required For The Establishment And Sustainability Of Community-Owned Renewable Energy District Heating Systems In Ireland, Gerard Doyle

Reports

International reviews of countries’ progress at tackling climate change show that Ireland is making small levels of progress on tackling issues associated with climate change. This paper will examine a theoretical framework, referred to as capacity analysis, to explain the capacities that need to be in place for the successful implementation of community-owned renewable energy district heating initiatives. The theoretical framework employed here is based on the ‘conceptual framework’ developed by Pringle which consists of four categories of capacity. The research methodology involves a case study with cases from Austria, Northern Ireland, the Republic of Ireland, Wales and Scotland. The ...


Generational Aspects Of U.S. Public Opinion On Renewable Energy And Climate Change, Lawrence C. Hamilton, Joel N. Hartter, Erin Bell Jan 2019

Generational Aspects Of U.S. Public Opinion On Renewable Energy And Climate Change, Lawrence C. Hamilton, Joel N. Hartter, Erin Bell

Sociology Scholarship

The topics of climate change and renewable energy often are linked in policy discussions and scientific analysis, but public opinion on these topics exhibits both overlap and divergence. Although renewable energy has potentially broader acceptance than anthropogenic climate change, it can also sometimes face differently-based opposition. Analyses of U.S. and regional surveys, including time series of repeated surveys in New Hampshire (2010–2018) and northeast Oregon (2011–2018), explore the social bases of public views on both issues. Political divisions are prominent, although somewhat greater regarding climate change. Such divisions widen with education, an interaction effect documented in other ...
