What are hydrogen tanks used for?
As the automotive industry evolves, hydrogen technology is becoming increasingly relevant, particularly in the realm of eco-friendly transportation. Hydrogen tanks play a crucial role in this transition, serving various applications that extend beyond just powering vehicles. In this article, we will explore the primary uses of hydrogen tanks and their significance in today's world.
What Are Hydrogen Tanks?
Hydrogen tanks are specialized containers designed to store hydrogen gas at high pressures. These tanks are engineered to safely hold hydrogen, which is a clean fuel alternative that can be used in various applications, including fuel cell vehicles, industrial processes, and energy storage systems.
Primary Uses of Hydrogen Tanks
- Fuel Cell Vehicles: Hydrogen tanks are essential for fuel cell electric vehicles (FCEVs), where they store hydrogen that is converted into electricity to power the vehicle. This process emits only water vapor, making it an environmentally friendly option.
- Industrial Applications: In industries such as refining and chemical manufacturing, hydrogen is used as a feedstock for producing ammonia, methanol, and other chemicals. Hydrogen tanks facilitate the storage and transport of this vital gas.
- Energy Storage: Hydrogen can be used as a means of storing excess energy generated from renewable sources like wind and solar. When energy production exceeds demand, it can be converted into hydrogen, which can later be used to generate electricity when needed.
- Space Exploration: Hydrogen tanks are utilized in rocket propulsion systems. Liquid hydrogen serves as a fuel for rockets, providing the necessary thrust to launch spacecraft into orbit.
- Heating and Power Generation: Hydrogen can be burned to produce heat or used in gas turbines for power generation, offering a cleaner alternative to fossil fuels.
Conclusion
Hydrogen tanks are pivotal in advancing sustainable energy solutions across various sectors. Their ability to store hydrogen safely and efficiently opens up numerous possibilities for reducing carbon emissions and transitioning to a cleaner energy future. As technology continues to develop, the role of hydrogen tanks is likely to expand, further integrating hydrogen as a key player in the global energy landscape.

What are the disadvantages of hydrogen storage?
Cons of Gas Hydrogen Storage
Higher storage volume – Since hydrogen gas is low-density, more space is required to store it—even when it's under pressure. Purchasing and maintaining additional storage facilities can steeply increase your costs.
What is hydrogen fuel mainly used for?
Nearly all of the hydrogen consumed in the United States is used by industry for refining petroleum, treating metals, producing fertilizer and other chemicals, and processing foods.
Why is hydrogen so difficult to store?
But liquid hydrogen storage is technically complex and, as such, has historically been very costly. Hydrogen has to be cooled to -253°C and stored in insulated tanks to maintain this low temperature and minimize evaporation. This requires a complex plant.
What is the biggest problem with hydrogen cars?
Difficult to transport, difficult to handle, and is not available at home. Poor conversion efficiency (see below chart) within the vehicle leading to energy losses and high fuel costs. Higher lifetime costs of FCEVs, almost exclusively due to the higher fuel cost.
What are the 3 main uses of hydrogen?
Hydrogen can be used to power vehicles, generate electricity, power industry and heat our homes and businesses. It could make a huge difference on our carbon emissions and will be critical to achieving net zero.
Why is hydrogen fuel not the future?
The Problem
While hydrogen itself is a clean fuel, the process of extracting it is, at present, not climate-friendly and very energy-intensive. Depending on the method and technology used, extracting it may use more energy than it provides as a fuel. Production of hydrogen from coal and natural gas also releases CO2.
How safe are hydrogen tanks?
A number of hydrogen's properties make it safer to handle and use than the fuels commonly used today. For example, hydrogen is non-toxic. In addition, because hydrogen is much lighter than air, it dissipates rapidly when it is released, allowing for relatively rapid dispersal of the fuel in case of a leak.
Why we don't use hydrogen fuel?
But hydrogen is a highly flammable and corrosive element, and it would be costly to repurpose oil and gas infrastructure to make it safe for hydrogen. And while hydrogen is not a greenhouse gas, it is not harmless. It aggravates some greenhouse gases, for instance causing methane to stay in the atmosphere for longer.
What is hydrogen storage used for?
Hydrogen storage is a key enabling technology for the advancement of hydrogen and fuel cell technologies in applications including stationary power, portable power, and transportation.
