Investigating the state of renewable energy and concept of pump as turbine for energy generation development

Access to consistent and clean energy is a key challenge faced by several countries globally; especially in Asian and African countries. Most of the communities within these and other regions in the world are faced with continuous energy crisis, causing most of these economies to cripple. It is esti...

Using the centrifugal pump to operate as turbine (PAT), is one of the best alternatives for small and micro hydro generation since it helps in meeting energy needs. Furthermore, it can also help improve economic growth due to its cheapest source of power generation as well as providing sustainable energy source that will create more employment opportunities to improve the socio-economic environments of the people. Moreover, PAT method are also advantageous because of its low cost in acquisition and maintenance. The characteristics of PAT have been discussed numerically to analyze pressure and velocity distribution at different rotational speeds. The study concludes that PAT is the best alternative for energy generation.http://www.sciencedirect.com/science/article/pii/S2352484720312750Pump as turbineRenewable energyPressure distributionEnergy storage
