To summary, both the optimal power system configuration and energy management strategy can be derived with the developed integrated optimization method, aircraft hydrogen economy and FC anti-aging performance can be significantly improved.
Meanwhile, based on the comprehensive analysis of hydrogen economy, FC aging cost, and aircraft stability, a multi-objective parameter sizing model is established to optimally size aircraft energy storage systems and hyper-parameters in power controllers.
To improve efficiency, the rated power of FC should be enlarged, which could bring serious weight penalty problems for the aircraft. After the battery is deployed in the aircraft energy storage system, the working points of the FC stack can be generally moved to the high-efficiency zone.
Specific parameters of aircraft propulsion and power system. The energy storage system of the studied aircraft consists of a 47-kWh battery pack that weighs 390 kg. In this study, the FC stack is used to substitute its original battery energy storage system to extend endurance.
Based on the comprehensive analysis of hydrogen economy, FC aging cost, and aircraft stability, a multi-objective parameter optimization model is established to decide the size of aircraft energy storage systems and hyper-parameters in the power controller.
The actual aircraft power system performance is evaluated under two scenarios: full voyage (5000 s), which includes takeoff, cruising, and landing three phases; short-term voyage (2500 s), which only consists of takeoff and landing two phases.

In this study, the technical and economic feasibility of employing pumped hydroelectric energy storage (PHES) systems at potential locations in Jordan is investigated. In each location, a 1 MWp off-grid photovoltaic (PV) system was installed near the dam reservoir to drive pumps that transfer water up to an upper reservoir at a certain distance and elevation. …
Spaarbekken 1 van de waterkrachtcentrale van Coo-Trois-Ponts. Wereldwijd gebeurt 99% van de energieopslag in pompcentrales (PHES, Pumped Hydro Energy Storage of SPHS, Seasonal Pumped Hydropower Storage).Dit zijn waterkrachtcentrales die bij elektriciteitsoverschot water van een lager naar een hoger gelegen spaarbekken pompen. Bij tekort aan elektriciteit stroomt …
Pressure Head of a Pump or Turbine. The power,, of a pump or turbine can be expressed as (39) The mass flow rate,, is (40) where is the volume flow rate. Therefore, (41) Of course, no pump or turbine can be 100% efficient, so if the efficiency is, then the power is (42) Therefore, in the case of a pump (energy in) of power, then (43)

The energy of chemical lasers directly comes from the release of molecular bond energy in chemical reactions, which has the highest energy storage density in nature except for nuclear energy. The specific power of HF/DF chemical lasers was more than 100 J/g, which was much higher than CO2 lasers. Following the initial demonstra-

Mixed-flow waterjet pumps (M-FWPs) are core units of high-speed ship power propulsion. When operated under non-optimal operating conditions, the unstable flow generated in the flow passage leads to a reduction in pump efficiency. This article investigates the energy loss mechanism of M-FWPs under different operating conditions through entropy production …
