Relevance of Energy Storage Technology in the Development of Solar Power

There is a growing concern in the operating of solar power as a stand-alone and its connection to the grid. This is because; its power quality and sustainability are being affected by intermittency and variability. As the time of the day and the solar intensity changes, the quality of power generation is affected. This has made the use of energy storage inevitable for a quality power generation. This paper considers some existing technologies of energy storage that is applicable in mitigating the challenge facing the deployment of solar power systems. The variability and effectiveness of these storage techniques were considered in terms of technology, efficiency, environmental impact, and response. In conclusion, it was resolved that a self-sufficient solar power system requires appropriate storage techniques to complement its operation. Therefore, understanding the different options of storage is required for a careful selection of the technology which can support the required level of efficiency and effectiveness in electrical energy generation.

Developing Flood Resilient Buildings in Nigeria: A Guide

Acknowledgements We acknowledge the support of the UI Ibadan TETFUND IBR 2016 Research Project Fund. Abstract Recently, the damage caused by flood in Nigeria has become unbearable leading to series of economic losses. Several post flood measures taken has proved to be inadequate because they are temporary. Hence, the needful is the flood risk management. Managing the risk of flood can be achieved by enhancing the resilient of the buildings in Nigeria. This requires a pragmatic approach from the concerned stakeholders. In this paper, we observed and discussed some of the drawbacks in Nigeria buildings leading to its vulnerability to flood. Also, guide was developed for government and stakeholders to achieve the incorporation of resilience in Nigeria building and its environment. Expected resilience was proposed and a flowchart to assist the prospective builders was developed. This will assist in developing the necessary blueprint towards achieving this goal. Necessary suggestions made will aid in the actualization of a resilient buildings within Nigeria. Keywords: Flood, resilience, Nigeria, flood risk management, buildin

Pumped-Hydro Storage Systems and Flood Risk Mitigation: a Proposed Nexus

Pumped-Hydro Storage (P-HS) technology has received some significant attention in energy storage. However, its application towards flood risk mitigation is a new dimension, which merits consideration given some of the technical characteristics and the system’s components. This study draws on a synthesis of the existing body of knowledge to postulate the potential nexus between P-HS operation and flood risk mitigation. This study represents the first attempt to explore the potential application of P-HS towards mitigating flood risk and also considers some of the other multiple benefits. The study raises a number of questions and considerations including, for example, what is the link between energy storage and flood risk mitigation?; what are the key areas that require consideration for the application of P-HS in flood risk mitigation?; how can the development of P-HS benefit flood risk mitigation? and how can this be achieved in a way that draws the interests of stakeholders and investors? A conceptual framework that seeks to establish these links alongside key areas that require consideration in line with the proposed application of P-HS in flood risk mitigation is presented. Thereafter, a discussion of the multiple benefits that P-HS could provide is presented, including improved environmental resilience as well as wider economic benefits
