In order to solve the problem that the traditional operation and maintenance system of photovoltaic operation and power station is mainly based on statistical analysis and multisite and multilevel deployment mode, which wastes software and hardware resources, is not easy to expand and has extremely low efficiency, which cannot meet the urgent needs of users to reduce costs and increase efficiency. This research proposes a methodology for integrating big data, cloud computing, and photovoltaic operation and maintenance. This method constructs the business model, data model, application model, and technical model of the photovoltaic power station operation and maintenance cloud platform. The results obtained are as follows: the system provides diagnostic services for the application system of a 30 MWp photovoltaic power station in a certain place, and a total of 87 defects are found, the defect elimination rate is 88.51%, and the monthly power generation of the power station is increased by 122,529 kWh; the use effect of the system in this research after it goes online. The evaluation is 93.04 points, ranging from very satisfactory (A) to satisfactory (B) and biased towards A, indicating that the use effect is good. It is proved that the successful research and promotion of the system in this research will be of great significance to improve the intelligent operation and maintenance level of photovoltaic power plants and improve the operation and maintenance efficiency of photovoltaic power plants.

The current trend is to use renewable energy such as solar energy and wind energy to produce hydrogen. It is necessary for us to make a comparison of the effect of each of these sources on hydrogen production, and which one is more efficient in different environmental variables. This paper studied and modeled two sources of renewable energy which are Photovoltaic (PV) and Wind Turbine (WT) to power Polymer Electrolyte Membrane Electrolyzer (PEMEL). By using MATLAB software, it is measured the input, and output power of PV and WT, the efficiency of the MPPT controller, and calculated the green hydrogen production rate and efficiency of each system separately. It is analyzed under variable irradiance from 600 to 1000 W/m2 for a PV system and fixed temperature equal to 25°C. While under variable wind speed from 10 to 14 m/s and zero fixed pitch angle for WT system. The results obtained that, the optimal power of WT to feed PEMEL is to be approximately two times PEMEL powered. Also, PV system is designed to be equal to PEMEL power. This study will be a reference for designing PV or WT to feed an electrolyzer.

“…The usage of energy storage systems for supporting the dynamic of the grid supports is recommended. A solution to stabilize the grid so that it is able to absorb excessive power generation, and to provide energy when power generation must be compliant with decarbonization targets (meaning avoiding generator turn-off) is given by hydrogen as a storage system [74]. Moreover, a coupling among different sectors aimed to connect the building heating, industry sectors, and transportation, as energy consumers with the power generation distribution system, can give more engaging options to assure stability.…”

Hydrogen is recognized as a promising and attractive energy carrier to decarbonize the sectors responsible for global warming, such as electricity production, industry, and transportation. However, although hydrogen releases only water as a result of its reaction with oxygen through a fuel cell, the hydrogen production pathway is currently a challenging issue since hydrogen is produced mainly from thermochemical processes (natural gas reforming, coal gasification). On the other hand, hydrogen production through water electrolysis has attracted a lot of attention as a means to reduce greenhouse gas emissions by using low-carbon sources such as renewable energy (solar, wind, hydro) and nuclear energy. In this context, by providing an environmentally-friendly fuel instead of the currently-used fuels (unleaded petrol, gasoline, kerosene), hydrogen can be used in various applications such as transportation (aircraft, boat, vehicle, and train), energy storage, industry, medicine, and power-to-gas. This article aims to provide an overview of the main hydrogen applications (including present and future) while examining funding and barriers to building a prosperous future for the nation by addressing all the critical challenges met in all energy sectors.
