View the hydrogen energy chain distributing: from the hydrogen storage end to the fuel cell application

 Hydrogen storage is an important bridge connecting hydrogen production and hydrogen use, and the hydrogen energy industry chain mainly includes four links: hydrogen production, storage and transportation, refueling and application. Among them, hydrogen refueling stations and hydrogen storage tanks are the core of the hydrogen industry chain, which mainly play a role in the transition between hydrogen energy and hydrogen energy. Hydrogen refueling stations use electrolysis tanks as the source of hydrogen charging for hydrogen fuel cell vehicles, while hydrogen storage tanks are responsible for the storage and transportation of hydrogen. This article will focus on the use of hydrogen in the hydrogen energy chain.

Many people do not know the principles involved and would a whole system from hydrogen production to electricity consumption, such systems exist, but with the current application of hydrogen storage tanks, only small power demonstration installations can be realized, because high-power hydrogen fuel cells require larger tanks, which would result in no system large enough to fit the tanks. Therefore, a separate selection of hydrogen products in different combinations can be realized for higher power pursuits. In this article, we will not only talk about the hydrogen industry chain, but also introduce how to select hydrogen products, which are based on the amount of hydrogen produced by the electrolyzer, the capacity of the hydrogen storage tank, and the amount of hydrogen consumed by the fuel cell, focusing on the example of a system with a 6KW hydrogen stack.

Hydrogen production end 

Take 1 Nm3/ h PEM electrolyzer and 3 Nm3/ h ALK electrolyzer as an example, they could produce hydrogen gas separately 1000L and 5000L per hour.

Hydrogen storage end

The 40L solid-state hydrogen storage tank can hold about 26,000 L of hydrogen.

1) 1 Nm3/h PEM electrolyzer 26000L/ 1000L ≈ 26h, take about 26 hours to fill a 40L hydrogen storage tank

2) 3 Nm3/h ALK electrolyzer 26000L/ 3000L ≈ 8.7h, take about 8.7 hours to fill a 40L hydrogen storage tank

3) 5 Nm3/h ALK electrolyzer 26000L/ 5000L ≈ 5.2h, take about 5.2 hours to fill a 40L hydrogen storage tank

Hydrogen terminal

1）Single hydrogen fuel cell stack
There is no limit to the use of hydrogen, one is to make it into a battery that can generate electricity, and then from the hydrogen storage tank or electrolyzer transition device, the hydrogen is transported to the fuel cell for direct use and power generation, which is more simple and direct, usually disguised as a generator and automobile engine, playing the role of only focusing on power generation.

The 6KW hydrogen fuel cell stack hydrogen consumption about 4380L per hour, which could make a 49L hydrogen storage tank to provide hydrogen gas consecutively 5.93 hours for it.

2) Expansion of fuel cell applications

The other is to incorporate the fuel cell into the system of a device to make it look better and make it easier to move around. Generally speaking, this type of fuel cell can be applied to a wide variety of fields, as long as a device needs to be driven, then the application of fuel cells to the device will have unlimited possibilities.

3D model of fuel cell system

Hydrogen fuel cell used for UAV. Compare to conventional hydrogen fuel cells, this battery has a little different and only designed for drone, it owns DC and DCAC, which respectively responsible for the conversion and allocation of electric energy. DC provides a stable power output to the battery and motor, while DCAC converts the direct current generated by the hydrogen stack into alternating current to drive the motor of the drone.

Uav battery energy solutions

The application of hydrogen energy can be widely penetrated into all aspects of traditional energy, including transportation, industrial fuel, power generation, etc., and the main technologies are direct combustion and fuel cell technology. Now more than one-third of the central enterprises have been in the layout of the whole industrial chain, including hydrogen production, storage, hydrogen refueling, hydrogen use and other layouts. By 2050, hydrogen energy will be widely used in transportation, energy storage, industry, construction and other fields, the output value of the hydrogen energy industry chain will expand, the industrial output value will exceed 10 trillion yuan, and the country will enter a hydrogen energy society.
