Hydrogen tanks for sale

Types of hydrogen tanks for sale

Hydrogen tanks can be classified into several types based on the form of hydrogen they store and the technologies used in their construction.

• Compressed hydrogen tanks

  The most common hydrogen fuel tank in vehicles uses this kind of tank, where hydrogen is held under great pressure, usually at 350 to 700 bars. These tanks are manufactured from pricey materials such as carbon fibre-reinforced polymers or aluminium alloys to sustain huge pressures.

• Liquid hydrogen tanks

  These tanks store hydrogen in its liquid state, which requires extremely low temperatures (around -253°C or -423°F). These tanks frequently incorporate insulation systems such as multilayer insulation or vacuum insulation to maintain the low temperatures required for storage. Liquid hydrogen is a dense energy form; however, it is more intricate and less common than storage options for gaseous hydrogen.

• Metal hydride tanks

  Metal hydride tanks use hydrogen-absorbing metals to store hydrogen. These tanks' design and function depend on the specific metal hydride alloy used, which may be nickel, titanium, zirconium, or other metals. These tanks are sealed pressure vessels in which the hydride-producing metal is stored in a hybrid or compressed form.

• Chemical hydrogen storage tanks

  These tanks store hydrogen in chemical forms, such as liquid organic hydrogen carriers (LOHC) or ammonia. Unlike physical storage methods, these carriers need a chemical reaction to release hydrogen, which involves complex tank designs and materials that can withstand chemical interactions (e.g., corrosion-resistant materials).

• High-pressure hydrogen tanks

  Most hydrogen storage solutions are high-pressure tanks that can hold hydrogen gas at pressures of up to 700 bar or more. These tanks are made of composite materials, including carbon fibre-reinforced polymer and aluminium, offering a good strength-to-weight ratio. These tanks are ideal for portable and transportable applications.

• Hydrogen storage spheres

  These tanks are often employed for large-scale industrial applications or in regions where a volatile organic chemical may be suitable for long-term storage. Moreover, due to their spherical shape, they can withstand pressure evenly, making them an efficient storage space for compressed hydrogen gas. Commonly used materials include steel or specialised alloys due to their robustness and resistance to the effects of pressure.

Design of hydrogen tanks for sale

The design of hydrogen tanks varies depending on the storage method, whether under pressure, in liquid form, or via metal or chemical hydrides.

• Compressed gas tanks: These tanks often use a composite cylinder design, typically an aluminium or steel core reinforced by carbon fibre. The internal pressure gives the cylinder strength, while the composite wrapping reduces the overall weight. Users may find pressure gauges and regulators in the cylinder's valve or neck area, which help monitor and change the pressure of the contained gas, while the neck or valve section is capped with a high-pressure, tightly sealing valve/delivery system to prevent gas escapes. A safety device called a rupture disc or burst panel is fitted to the tank, which opens at a certain pressure to release gas and avoid cylinder rupture during overpressure.
• Liquid hydrogen tanks: Liquid hydrogen storage tanks are typically vacuum-insulated in a double-walled container. The outer wall is made of stainless steel or alloy steel, while the inner wall is austenitic stainless steel to maintain ultra-cold temperatures. Insulation is usually thick-layered using perlite or molecular sieve insulation, which keeps the liquid hydrogen at the required temperature. They include pressure relief systems to manage the small amount of hydrogen that evaporates.
• Metal hydride tanks: Metal hydride tanks normally consist of a pressure vessel containing a metal alloy that absorbs hydrogen. The vessel is made of steel or other robust materials to guarantee security, and the hydride-forming metal may be in powder or solid form to create an alloy. These systems may involve heating elements or other designs that enable hydrogen release by restoring the alloy. The pressure vessel storing the metal hydride is typically constructed from high-strength steel, although other robust materials like titanium may be used, ensuring the safety and integrity of the design under high pressures.
• Chemical hydrogen storage tanks: LOHC and ammonia systems use storage vessels made from steel or other materials compatible with specific chemicals. Pumps, reactors, or other components are integrated into the design to facilitate chemical reactions and hydrogen release. Pipeline systems with compatible materials carry ammonia or other hydrogen-storing substances through long distances.

Specification & Maintenance of hydrogen tanks for sale

There are some specifications and maintenance of hydrogen tanks.

• Work pressure: Compressed gas tanks should have a design pressure of at least 700 bar to ensure the tank operates under the high pressures the gas will be stored in safely.
• Material: Tanks are usually made from composite materials, such as carbon fibre reinforced polymer on an aluminium or steel core, which have high strength, low risk of corrosion, and are as light as possible.
• Inspect regularly: It is best to get the pressure relief device, cylinder, hose, and regulator checked frequently by an experienced professional. Address any signs of rust, dents, or damage found right away.
• Proper storage: Keep tanks in a vented, shaded area away from combustibles and heat sources, particularly direct sunlight. Store vertically and secure to prevent falling.
• Nikola hydrogen truck: The tank of a hydrogen truck near me is a compressed gas cylinder where hydrogen is kept under great pressure, requiring robust materials like carbon fibre reinforced polymer, aluminium, or steel. To ensure performance and safety, users should check pressure ratings, inspect age and damage, and adhere to maintenance guidelines. Users must regularly store and install safely to avoid hazards and leaks.

How to choose hydrogen tanks for sale

Hydrogen tanks are available in different sizes and specifications depending on the client's needs. Below are some of the factors that a client should consider when buying the tanks.

• Storage method

  The storage method is the first consideration. Tanks should be chosen based on how the hydrogen will be stored. For instance, use a compressed gas cylinder for the gaseous state. A liquid storage tank is ideal for storing hydrogen in liquid form. Metal hydride or chemical storage is best for solid or chemical storage.

• Storage capacity

  The desired hydrogen storage capacity of the customer should also be considered. a smaller tank is suitable if the client needs it for short-term storage or they usually need hydrogen for daily usage. However, a larger tank would be the best option if the user stores hydrogen for a longer time.

• Safety features

  Manufacturers must ensure that the hydrogen tanks have necessary safety features like pressure relief valves, leak detection systems, and appropriate ventilation. Buyers should also look for tanks that meet local and international safety standards and regulations.

• Material compatibility

  They should also ensure that the tank is constructed from materials that are compatible with hydrogen to avoid embrittlement. For instance, steel, aluminium, and composite materials are the best for storing hydrogen.

• Maintenance needs

  Maintenance requirements are also factors to consider in order to prevent long-term downtime. Customers prefer hydrogen tanks compatible with low-maintenance components. Additionally, they should look for tanks with easy access for inspection and maintenance. For example, The nikola hydrogen tank is ideal for keeping maintenance to the minimum level.

• Market

  Although the tanks function similarly, various consumers may prefer a specific brand. Buyers should consider the hydrogen tank retailers they would purchase from. They should ensure that the retailers have a good reputation and are known for offering quality products that have warranty/guarantee.

• Temperature range

  For optimal performance, buyers should choose tanks appropriate for the operating temperatures of their environment. They should select tanks that can retain their strength and integrity at extreme high or low temperatures. This will ensure the tanks can withstand customer's operating conditions.
