Pressure Vessels for Hydrogen Stations

In recent years, in the Industrial Machinery Products Business, to contribute to the reduction of energy
use we have been focusing on magnesium as a material that is lighter and more easily recyclable thanaluminum and supplying magnesium alloy injection molding machines, which are used to produce
notebook PC chassis, automobile parts, and other products, around the world. Meanwhile, hydrogen-derived energy has been gaining attention to curb global warming as exemplified in the gradual popularity in hydrogen fuel cell vehicles in the automobile industry. At JSW, we develop steel pressure vessels
for hydrogen stations that take advantage of our advanced steel technologies as our contribution to
the establishment of infrastructure for a hydrogen society. Some of the commercial hydrogen stations
have already adopted our pressure vessels.

FCVs run on fuel cells which generate electricity by a chemical reaction between hydrogen and atmosphere-derived oxygen. After thereaction, the car only emits water. Since FCVs don’t emit CO2 like internal-combustion vehicles, they are drawing much attention as anultimate eco-car. Amid an environment in which curbing global warming has become an urgent task, it is essential to realize a hydrogenbased society by promoting the spread of FCVs and constructing more hydrogen stations around the world that supply hydrogen to FCVs.
To contribute to realizing a hydrogen-based society, we have been combining our long-accumulated technologies and expertise insteel materials and hydrogen to supply highly reliable steel pressure vessels for hydrogen stations. We remain committed to the development of a future hydrogen society by providing safe and secure products underpinned by dependable technologies and expertise.

Magnesium has been drawing much attention as a material whose features include light weight, easy recyclability, and eco-friendliness.
As an example, magnesium alloy automobile parts are expected to improve fuel efficiency as a result of lighter body weight and prove
effective in curbing the emission of greenhouse gases.
When applied to the chassis of notebook PCs and cameras, magnesium contributes to reducing their overall weight to make it moreconvenient to carry around. Moreover, its superior recyclability makes it possible to repeatedly reuse the material to cut down on waste
generation.
Our magnesium alloy injection molding machines melt magnesium in a sealed cylinder. This renders it unnecessary to use non-flammable gas (mainly sulfur hexafluoride, a potent greenhouse gas that has a high global warming potential), which was needed in the conventional die casting method to prevent molten metal in the furnace from being exposed to the atmosphere. In this way, magnesium alloy
injection molding machines don’t emit greenhouse gases.
JSW will remain committed to the realization of a recycling-based society and the prevention of further global warming through thedevelopment of injection molding machines.

(70MPa)PrecoolingAt hydrogen stations that recharge hydrogen, which is the fuel for fuel cell vehicles (FCV), pressure vessels are essential for storing the hydrogen gas
at high pressure.
Some commercial hydrogen stations, for which construction began in 2013, use our steel hydrogen vessels.
In fiscal 2018, we developed a new pressure vessel featuring a longer product life at a more affordable price than the previous products.
