IV. Other Sectors

（1）Hydrogen-based Metallurgy: In the steel industry, it is used for the direct reduction of iron ore, replacing the traditional coke-based ironmaking process and reducing carbon dioxide emissions.

（2）Electronics Industry: It provides high-purity hydrogen for processes like reduction and cleaning in semiconductor manufacturing and electronic component production within the electronics industry.

Hydrogen is a very active reducing agent (fuel). Thus, in hydrogen-oxygen fuel cells, very high operating currents and high specific power values per unit weight can be achieved. However, the handling, storage, and transportation of hydrogen fuel is complex. This is primarily a problem for relatively small portable power plants. For such a plant, liquid fuels are more realistic.
Methanol is a very promising fuel for small portable fuel cells. It is more convenient and less dangerous than gaseous hydrogen. Compared to petroleum products and other organic fuels, methanol has a fairly high electrochemical oxidation activity (although not as high as hydrogen). Its chemical energy ratio content is about 6 kWh/kg, which is lower than that of gasoline (10 kWh/kg), but quite satisfactory. For this reason, its application in fuel cells for power plants in electric vehicles and different portable devices is widely discussed today.

The operation of DMFCs has fundamental problems that do not exist in proton exchange membrane fuel cells. In the latter, the membrane is practically impermeable to reactants (hydrogen and oxygen), preventing them from mixing. In contrast, in DMFC, the membrane is partially permeable by methanol dissolved in an aqueous solution. For this reason, some methanol penetrates from the anode part of the battery through the membrane to the cathode part. This phenomenon is called cross-curium-crustic ethanol. This methanol is directly oxidized by gaseous oxygen on a platinum catalyst without producing useful electrons. This has two consequences: (i) a significant portion of the methanol is lost in the electrochemical reaction, and (ii) the potential of the oxygen electrode shifts to a lower positive value, so the operating voltage of the fuel cell decreases. Despite many investigations conducted so far, it has not been possible to fully address this issue.
One potential application area for DMFC is low-power (up to 20W) power supplies for electronic devices such as laptops, camcorders, DVD players, mobile phones, medical devices, and more. At present, the application of DMFC as a power source for electric vehicles is very far away. Despite a great deal of research, DMFCs are still not in commercial production or widely used in practical use compared to proton exchange membrane fuel cells.

In the selection of hydrogen production technology, the choice between proton exchange membrane (PEM) electrolyzer and alkaline electrolyzer requires a comprehensive consideration of many factors. The following comparison will help you make a decision:

I. Technical performance

1. Current density and energy consumption

• Alkaline electrolyzer: The current density is usually 0.2–0.4 A/cm², and the system energy consumption of the two is similar.

• PEM electrolyzer: The current density reaches 1–2 A/cm², and the system energy consumption of the two is similar.

2. Load range and response speed

• Alkaline electrolyzer: Load adjustment range 40-100%, slow start and stop speed (hot start 1–5 minutes, cold start 1–5 hours), not suitable for intermittent energy such as wind power/photovoltaic power - pressure balance is required to avoid gas leakage.

• PEM electrolyzer: Load range 0%–120%, fast start and stop (hot start <5 seconds, cold start 5–10 minutes), very suitable for matching fluctuating renewable energy.

2. Cost factors

1. Equipment cost

• Alkaline electrolyzer: low cost, electrodes do not contain precious metals. The domestic market share is high, and the equipment price is only 1/4–1/6 of PEM.

• PEM electrolyzer: high cost (overseas price is 1.2–1.5 times that of alkaline, and 4–6 times that of domestic), because the catalyst requires precious metals such as iridium and platinum. However, overseas price performance is better, and domestic production is reducing costs through localization and scale.

2. Operating cost

• Alkaline electrolyzer: low equipment cost, high energy consumption, and energy consumption optimization in the future.

• PEM electrolyzer: low energy consumption can reduce costs, but equipment and precious metal expenses push up overall operating costs, and cost reduction depends on increasing current density, reducing iridium usage and localization.

3. Application scenarios

1. Alkaline electrolyzer applicable scenarios:

• Large-scale industrial hydrogen.

• Scenarios with low water quality requirements: ordinary deionized water can be used, suitable for areas with limited high-purity water supply.

2. PEM electrolyzer applicable scenarios:

• Renewable energy coupling scenario (wind power/photovoltaic): fast response, wide load range, suitable for off-grid distributed hydrogen production (such as islands, mining areas).

• High-purity hydrogen scenario (such as hydrogen refueling station): directly produce high-purity hydrogen without additional separation.

IV. Future trends

• Alkaline electrolyzer: focus on reducing energy consumption (upgrading diaphragms/catalysts) and improving current density to further optimize cost performance.

• PEM electrolyzer: through technological breakthroughs (reducing the use of precious metals), localization and scale-up cost reduction, it is expected that the market share will expand after the cost reduction.

Summary

• Choose alkaline electrolyzer: if the demand is large-scale low-cost hydrogen production, and the purity of the water source needs to be taken into account.

• Choose PEM electrolyzer: if you focus on fast response, adapt to the fluctuations of renewable energy, pursue high-purity hydrogen, and can accept a higher initial investment.

Green hydrogen is hydrogen obtained by splitting water from renewable energy sources such as solar and wind energy, and when it is burned, it produces only water, achieving zero carbon dioxide emissions from the source, so it has earned the excellent title of "zero-carbon hydrogen".
Although hydrogen energy is a clean and sustainable new energy source that does not emit carbon dioxide in the process of releasing energy, the current process of producing hydrogen energy is not 100% "zero-carbon". For example, the production of gray hydrogen and blue hydrogen, the other two brothers of green hydrogen, is divided into three categories: gray hydrogen, blue hydrogen, and green hydrogen, according to the source of production and the emissions in the production process.
Grey hydrogen is produced by the combustion of fossil fuels such as oil, natural gas, coal, etc., and although the manufacturing process is low-cost, gray hydrogen is the least popular among the "three brothers" due to the large amount of carbon dioxide emitted from the whole process.
Blue hydrogen is an "upgraded" version of grey hydrogen, made from fossil fuels such as coal or natural gas. While natural gas is also a fossil fuel and produces greenhouse gases when producing blue hydrogen, advanced technologies such as carbon capture, storage and utilization can capture greenhouse gases and ultimately enable low-emission production with reduced environmental impact. Grey hydrogen is used as a fuel for transportation, which actually emits more than direct diesel and gasoline. Compared with grey hydrogen obtained from industrial raw materials, green hydrogen is more pure and has fewer impurities, making it more suitable for fuel cell vehicles and promoting the clean transformation of the transportation sector.
In the chemical industry, hydrogen is often used as a feedstock for the production of ammonia methanol and other chemicals. The emergence of green hydrogen not only contributes to the deep decarbonization of the ammonia production process, but also replaces natural gas and coal for the production of green methanol, reducing carbon emissions in the production of chemicals.
In addition, asphalt can also solve the problem of excess renewable energy generation, and reuse curtailment of wind, solar and water, thereby increasing the utilization rate of renewable energy.
In 2022, the proton exchange membrane water electrolysis hydrogen production system of the Dachen Island Hydrogen Energy Comprehensive Utilization Demonstration Project in Zhejiang Province successfully achieved hydrogen production. Tourism and aquaculture are the island's two pillar industries, and the "green hydrogen ™ integrated energy system can supply electricity and heat for homestays, hotels, villas, etc." The oxygen produced in the hydrogen production process can be provided to yellow croaker farmers, giving full play to the value of hydrogen production by-products and providing impetus for the development of the local aquaculture industry. Green hydrogen is so good, isn't its appearance fee very "expensive"? The amount of electricity required to produce hydrogen by electrolysis is huge, and it takes about 50 kilowatt-hours of electricity to produce one kilogram of hydrogen, which is prohibitively expensive. However, with the further maturity of wind power, tidal power, solar power generation and other technologies, the production cost of green electricity has been reduced, which indirectly reduces the production cost of green hydrogen.
Green hydrogen is no longer "unattainable", and the production of hydrogen through electrolysis of water through photovoltaic power generation not only achieves no carbon emissions in the production process, but also achieves zero carbon emissions in the use process, achieving truly double the clean. It is believed that with the further maturity of future technologies, "green hydrogen" will become one of the important and major new energy sources in the future, and contribute more to the realization of the dual carbon goals.
