Background
The hydrogen energy is ideal clean energy, the current technology for producing hydrogen by electrolyzing water is mature, the equipment is simple, the hydrogen production process is pollution-free, and the purity of the obtained hydrogen is high. However, the technology still has the possibility of continuous optimization, and the aim of optimization is to improve efficiency and reduce cost. For this purpose, we have improved the electrode plate, and related patents are in the application.
At present, most of established hydrogen stations need to frequently transport a large amount of hydrogen, and the transportation cost and the safety protection cost are high. The main reason why the electrolytic water hydrogen production cannot be widely applied to the hydrogen adding station is that the hydrogen adding station can stop hydrogen production when hydrogen is excessively stored due to uncertainty of hydrogen demand, and current is increased to quickly produce hydrogen when the hydrogen is not supplied, so that impact can be generated on a power grid, and the high current can seriously heat electrolytic equipment and accelerate the loss of electrodes.
The distributed water electrolysis hydrogen production scheme is to use a power supply as an energy source, establish a skid-mounted hydrogen adding station at a place where power and water can be supplied, and only consume electricity, water and auxiliary materials to produce and supply hydrogen. The power supply can be a power supply network for supplying power, wind power, photoelectricity and the like, and can be used in areas with poor environmental conditions and power supply conditions. The hydrogen production, purification, hydrogen storage and hydrogenation are all controlled automatically, an information acquisition system of various sensors is configured, and the hydrogen production task and speed of the hydrogenation station can be regulated and controlled by combining information remote transmission, artificial intelligence, big data and cloud computing, so that the hydrogenation station can continuously produce hydrogen, purify and store hydrogen with smaller current according to potential hydrogen demand, and simultaneously can supply hydrogen in a sufficient quantity at a very high speed.
