Suppliers provide these types of industrial hydrogen gas in bulk, often using them as product keywords.
Refineries need a lot of chemical hydrogen, which means they require a steady supply and large quantities. Chemical manufacturers also need chemical hydrogen for desulfurizing, which removes sulfur from fuels. Metal producers use chemical hydrogen for hydrometallurgical processes like hydrogen reduction of metal oxides to recover pure metals. Ammonia producers use chemical hydrogen as a major component for the synthesis of ammonia (NH₃) through the Haber process. Indeed, this is only to mention but a few industrial areas where chemical hydrogen finds application.
Just like industrial hydrogen gas, liquid hydrogen is high-purity hydrogen. It is stored in liquid form at extremely low temperatures, at about -253 °C. It is commonly used in space exploration as a rocket fuel because of its high energy content, making it effective in propelling rockets and spacecrafts.
Cube hydrogen is a new innovation for effective storage of hydrogen gas. It is an efficient method of storing large amounts of hydrogen gas using high pressure, usually at 200 to 400 bar. It is designed as transportable containers or modular storage units. It finds applications in providing hydrogen fuel Tesla-like electric vehicles and industrial processes.
The most common type of hydrogen produced today is grey hydrogen. Natural gas is used to produce it through a method called steam methane reforming (SMR). Grey hydrogen does not have any carbon capture and storage (CCS) technology attached to its production process. Therefore, its production releases large amounts of carbon dioxide (CO₂) into the atmosphere, contributing significantly to global warming and climate change.
Grey hydrogen is produced from brown coal (lignite) using gasification, which is a process that converts solid carbonaceous material into gaseous products. It is commonly used in regions with abundant lignite deposits. Like grey hydrogen, brown hydrogen emissions are high, making them detrimental to the environment.
Grey blue hydrogen is very much like grey hydrogen. The only difference it has are CCS technologies that capture and store some of the carbon dioxide emissions produced in the hydrogen production process. By incorporating CCS, carbon emissions are reduced by 30 to 50 percent. It can help transition industries to lower-carbon alternatives while still utilizing fossil fuels as a temporary solution.
Green hydrogen is environmentally friendly. Renewable energy sources like wind, solar, and hydro power produce it. Electrolysis is the process used in producing it, where water (H₂O) is split into hydrogen and oxygen (O₂) using electricity from renewable sources. Because of its zero carbon emissions, it has a lower environmental impact than other types of hydrogen.
Buyers resell this industrial hydrogen gas to various businesses that use it in these ways.
Hydrogen is used to remove sulfur from fuels, which makes the fuel cleaner and reduces pollution when used. It is also used in hydrocracking, a process that uses hydrogen to break down heavy oil fractions into lighter, more valuable fuels like gasoline and diesel.
Hydrogen is used in the Haber process to produce ammonia, an essential ingredient for fertilizers. Those in chemical manufacturing industry use hydrogen for producing a wide range of chemicals such as hydrochloric acid (HCl) and methanol (CH₃OH), which are then used for various industrial applications.
In metal industries, hydrogen is used for hydrogen annealing, a heat treatment process that helps to relieve stress in metals, making them stronger and reducing the risk of breaking or failing during use. Hydrogen is also used for hydride forming, which involves the absorption of hydrogen into certain metals to form metal hydrides that store energy for longer periods of time. Hydrogen is also used for reducing metal oxides in pyrometallurgical extraction of metals, thereby purifying them.
As mentioned earlier, hydrogen and oxygen are combined in a fuel cell to produce electricity, water, and heat. Therefore, hydrogen is a clean fuel for vehicles and machines, especially in places where battery electricity would be too time-consuming or logistically impractical to install.
The electricity generation of nuclear reactors can be very high, about enough to power millions of homes. Excess hydrogen is used to help cool the reactors and therefore make them safer.
A number of factors influence the prices of hydrogen gas as follows.
The most common way of producing hydrogen is by steam methane reforming (SMR). It is a cost-effective method, but since it uses fossil fuels, the carbon emissions are also high. Since green hydrogen is produced with renewable energy through electrolysis, its production cost is high. For a firm, the method of production they choose will influence the price at which they get industrial hydrogen gas.
The costs of raw materials used for producing hydrogen directly affect the price. Because natural gas is the primary feedstock for producing grey and black hydrogen, any fluctuations in natural gas prices significantly impact the cost of hydrogen production. Higher natural gas prices lead to higher hydrogen costs, whereas lower prices would reduce them.
The electrolysis method used to produce hydrogen requires massive amounts of electricity. Therefore, electricity prices significantly impact hydrogen production costs. Price fluctuations, such as seasonal changes in electricity demand or changes in energy policy., can directly affect the gas price.
The kind of technology employed during production affects the price. High-priced electrolysis equipment for green hydrogen production will increase the hydrogen gas price, whereas older, less efficient technology might not.
There are a number of ways industries hydrogen gas prices can be kept sustainable.
First, CCS could be incorporated during production to prevent carbon emissions and thus reduce the price.
Second, utilizing renewable energy for hydrogen production could dramatically reduce electricity costs and hence the price of the gas.
Finally, optimizing production efficiency by investing in advanced technologies and maintenance of the equipment could help reduce the production cost and thus the gas price.
The balance between the available hydrogen supply and the buyer's demand has a big influence on the price. When there is high demand and limited supply, the price goes high, but when there is low demand and abundant supply, it drops. Any changes in the balance, such as the growth of hydrogen usage in an industry or shortages in production can affect the price of the gas.
Transportation costs are influenced by the distance between the production site and the consumption area. Longer distances increase the cost. Similarly, storage costs in the transportation medium or in storage facilities affect the gas prices.
The impact of environmental policies and regulations on price can be direct or indirect. Policies such as carbon pricing, emissions trading, and subsidies for green hydrogen production can affect the cost of production and therefore influence the gas prices. Meeting the hydrogen purity requirements in certain applications can increase production costs and thus increase the price.
A number of strategies can be employed to sustain industrial hydrogen gas.
Using renewable energy sources like solar, wind, or hydropower to produce green hydrogen can make the production more sustainable and reduce the industrial hydrogen gas price. This will avoid the use of fossil fuels and reduce the carbon emissions associated with the production process.
Advancing electrolysis technology and using catalysts to enhance reactions can increase the efficiency of hydrogen production. Continuous monitoring and optimization of production processes can minimize energy consumption and gas losses, leading to higher yields and more sustainable production.
Storing hydrogen in high-strength composite materials or metal hydrides can make storage safer and more efficient. Composite materials allow for lightweight and high-strength storage solutions, while metal hydride storage involves absorbing hydrogen into a solid metal alloy, reducing gas volume and enhancing safety.
Hydrogen transportation in gaseous or liquid form can lead to losses due to leaks or incomplete transfer. For this reason, minimizing these losses is indispensable. One way to mitigate these losses is by using leak-proof containers and pipelines. Another way is by optimizing the containers to ensure maximum transfer efficiency.
Using hydrogen fuel cells for power generation instead of combustion can make better use of hydrogen energy. Fuel cells convert chemical energy directly into electricity, achieving higher efficiency and reducing the amount of hydrogen needed to meet energy requirements. This reduction in need will minimize waste and make production more sustainable.
This can be done by capturing and reusing hydrogen from industrial processes such as metal refining or chemical manufacturing. One way to capture it is by using exhaust gas or waste streams with high-hydrogen concentrations. This will then be purified and reused in the same or other processes.
Carbon capture and storage technologies can be used during hydrogen production to capture and store carbon emissions. This will reduce the overall carbon footprint of hydrogen production and allow industries to produce hydrogen more sustainably without contributing to climate change.
Buoying the value of industrial hydrogen to consumers hinges on its applicability in diverse industries. For instance, fuel cell electric vehicles utilize it as a clean fuel and an energy source for space exploration. Well, there is also the high purity industrial hydrogen used in electronic and pharmaceutical manufacturing, metal treatment, and ammonia production.
Buyers should consider the purity level first. The purity should be based on the use the buyer intends for the gas. Buyers should also get various hydrogen types like green, blue, grey, and brown. The method of production should also be a consideration. Buyers should also get a variety of quantities and qualities because they directly affect price and quality respectively.
When stored or transported under high pressure, hydrogen gas can pose great danger to the unsuspecting. This danger mostly occurs because hydrogen is highly flammable and, without caution, can cause fire and even explosion. Additionally, high concentration of hydrogen can cause hypoxia, which displaces oxygen and leads to asphyxiation.
Carbon emissions are reduced by 30 to 50 percent as a result of implementing carbon capture and storage during hydrogen production, hence minimizing the likelihood of climate change. Another benefit of implementing CCS is provision of additional revenue incentives for producers. This is because they can sell captured carbon for profitable uses such as enhanced oil recovery.
