Energy and Power Engineering 2024年第2期16卷 97-119页

作者： Olushola aina Nigerian Society of Engineers (NSE) Abuja Nigeria Nigeria Institute of Power Engineers (NIPE) Abuja Nigeria Institute of Electrical and Electronics Engineers (IEEE) Port Harcourt Nigeria

Energy in its varied forms and applications has become the main driver of today’s modern society. However, recent changes in power demand and climatic changes (decarbonization policy) has awakened the need to rethink through the current energy generating and distribution system. This led to the exploration of other energy sources of which renewable energy (like thermal, solar and wind energy) is fast becoming an integral part of most energy system. However, this innovative and promising energy source is highly unreliable in maintaining a constant peak power that matches demand. Energy storage systems have thus been highlighted as a solution in managing such imbalances and maintaining the stability of supply. Energy storage technologies absorb and store energy, and release it on demand. This includes gravitational potential energy (pumped hydroelectric), chemical energy (batteries), kinetic energy (flywheels or compressed air), and energy in the form of electrical (capacitors) and magnetic fields. This paper provides a detailed and comprehensive overview of some of the state-of-the-art energy storage technologies, its evolution, classification, and comparison along with various area of applications. Also highlighted in this paper is a plethora of power electronic Interface technologies that plays a significant role in enabling optimum performance and utilization of energy storage systems in different areas of application.

Dear Editor,The World Health Organization recently declared monkeypox as a global emergency after reporting more than 57,000 new cases worldwide[1].Monkeypox is an orthopoxvirus similar in nature to the Variola virus,which is a causative agent for smallpox[2].Monkeypox virus presents as a unique challenge for global health and should be regarded with grave concern as the vast majority of cases are occurring in countries where the disease is not considered ***,the spread of this pathogen is occurring concomitantly as the world is still engaged in a battle with the coronavirus disease 2019(COVID-19)pandemic,which has caused substantial damage to global healthcare *** monkeypox continues its rapid spread,hospitals could be quickly overwhelmed by both COVID-19 and monkeypox *** more than ever,early symptom recognition and use of all available treatments to contain monkeypox outbreaks are *** precautions including early recognition of symptoms by physicians,use of currently available treatments,and promoting precautionary measures in at-risk populations may be vital in preventing hospital burden and further physician burnout.
