Where is hydrogen currently used?

Hydrogen is an energy carrier and as such, a true multi talent. Today, hydrogen is directly used mainly in industrial processes of many kinds, such as ammonia fertilizer production, food processing purposes, the float glass industry, cooling for power plants and in the semiconductor and electronics industry, and many more.

Hydrogen also finds application as a fuel in transport often with water as the only by-product/emission. Vehicles with fuel cells on-board (cars, buses, trains, drones, planes) use hydrogen as the fuel to power their electric propulsion systems. But fuel cells are increasingly important in the power sector also. They can supply power to residential homes, commercial and industrial buildings, and remote locations. They can provide 24/7 power or serve as a backup power device. Hydrogen offers much greater energy storage density and longer autonomy than batteries.
