Material of Toyota Mirai Hydrogen Tank
The hydrogen fuel tanks of the Toyota Mirai are made of carbon-fiber-reinforced plastic. These tanks have been rigorously tested and proven to meet Global Technical Regulation No. 13, ensuring their safety and reliability. The carbon-fiber-reinforced plastic tanks store the hydrogen at a pressure of 700 bar, contributing to the overall efficiency and performance of the Mirai’s fuel cell system.
This material choice aligns with Toyota’s commitment to innovation and sustainability, as it enables the storage of hydrogen in a safe and efficient manner, supporting the vision for a future sustainable hydrogen society .

What are hydrogen car tanks made of?
Compressed hydrogen fuel tanks are now made of carbon fiber composites or carbon fiber and metal alloys and composites. The inner line of the tank is a high-molecular weight polymer that serves as a hydrogen gas permeation barrier. The outer shell is placed on the tank for impact and damage resistance.
What are the fuel tanks made of in Toyota Mirai?
The Toyota-designed carbon fiber hydrogen tanks have also undergone extreme testing to ensure their strength and durability in a crash.
What are the components of a hydrogen tank?
Schematic diagram of a liquid hydrogen tank and its components (1) Outer tank, (2) Inner tank, (3) Coupling (Johnston-Cox), (4) Heater, (5) Heat exchanger, (6) Cryogenic filling valve, (7) Cryogenic return valve, (8) Pressure regulation valve, (9) Shut-off valve, (10) Boil-off valve, (11) Safety relief valve, (12) …
What material is liquid hydrogen fuel tank?
Material chosen for the tank was 6061-T6 aluminium due to its low density and low material cost.
What is the new material for hydrogen storage?
Magnesium hydride (MgH2) is one of the most desirable hydrogen-storage materials, with high capacity both by weight and by volume. Certain lightweight metal amides, including lithium amide (LiNH2) are likewise promising, and have long been studied by the research community for their potential in hydrogen storage.
What is the best material for liquid hydrogen storage?
Liquid Hydrogen Tanks store hydrogen at near atmospheric pressure and require cryogenic materials, such as stainless steel or aluminum alloys, capable of withstanding the extreme temperatures of -253°C.
What is the best material for hydrogen storage?
Metal hydrides are very effective at storing large amounts of hydrogen in a safe and compact way. All the reversible hydrides working around ambient temperature and atmospheric pressure consist of transition metals; therefore, the gravimetric hydrogen density is limited to less than 3 mass%.
What metal are fuel tanks made of?
The most common materials for fuel tanks are metal or plastic. Metal (steel or aluminium) fuel tanks are usually built by welding stamped sheetmetal parts together.
What materials are hydrogen storage tanks made of?
Type I hydrogen tanks are made of metal only [48]. Common metals used include steel and aluminium alloys. Such hydrogen tanks are the easiest to manufacture among the five types and thus, the cheapest. They can be made to have a huge capacity and the working pressure is normally at around 200 bar [15].
Are fuel tanks made of plastic?
Typically, plastic fuel tanks are made from these five different materials: high density polyethylene (HDPE), polypropylene (PP), regrind plastic (recycled polyethylene), a plastic adhesive or ethyl vinyl alcohol (EVOH).
