Hydraulic regenerative braking system is an important branch of hybrid technology, which has the advantage of high power density and the ability to accept the high rates/high frequencies of charging and discharging, therefore hydraulic regenerative braking technology is well suited for off-road vehicles and heavy-duty trucks. Relatively lower energy density and complicated coordinating operatio...

The utilization of renewable energies as an alternative for fossil fuels is considerably growing due to an increasing environmental concern and exhaustion of fossil fuels [1-3]. Transportation electrification is one way to replace or reduce fossil fuels with renewable energy sources. Several propulsion systems including hybrid electric vehicles and plug in hybrid electric vehicles have been int...

Sediment erosion not only reduces efficiency and life of hydropower turbines but also causes problems in operation and maintenance. Several factors are responsible for this erosion in hydro turbine components. This paper presents the sediment erosion types in hydraulic turbines and their components based upon an extensive literature review and the field observation at Cahua hydropower plant, Pe...

The paper deals with the characteristics of three different types power train hybridization forest logging machines and benefits reducing environmental impacts by comparing new technology more conventional, older technology. New options that could be implemented in forestry are also discussed. divides a hybrid solution into classes based on energy used system hybridization. First is an electro-...

Hybrid plants where a fuel cell and a gas turbine are combined have attracted the attention of the power system community. In this paper, a model is provided of a Molten Carbonate Fuel Cell stack and of the thermo-hydraulic equipment in which it is embedded. The model is worked out from basic physical considerations; however, it is also simple enough for simulation and control purposes. Besides...
