FAQ

Hydrogen is used in many industrial processes such as refining petroleum, treating metals, producing fertilizers and processing foods.

Hydrogen is also used in space exploration in the liquid form as a rocket fuel.

Hydrogen fuel cells produce electricity by combining hydrogen and oxygen atoms. The hydrogen reacts with oxygen across an electrochemical cell to produce electricity. These hydrogen fuel cells can power electronics, supply electricity to power grids, supply emergency power in buildings and supply electricity in places that are not connected to electric power grids.

Hydrogen can be used as a fuel for power plant to generate electricity.

Hydrogen is used in the long-haul freight transportation industry as fuel for the hydrogen fuel cell vehicles due to its ability to power fuel cells in zero-emission vehicles and the fuel cell's potential for high efficiency. Hydrogen fuel cell trucks can replace polluting diesel freight trucks, according to the National Resources Defense Council (NRDC)

Green Hydrogen is the hydrogen generated by the process of splitting water into hydrogen and oxygen with renewable power such as wind, solar, hydro power etc.

Electrolysis is a method of splitting water into hydrogen and oxygen using the energy from an electric current. Electrolyzer is the equipment used to accomplish the process of electrolysis.

When fossil fuel is burnt, it provides heat energy. But also emits carbon dioxide, which is directly released into the atmosphere contributes to climate change. Whereas burning hydrogen only produces water vapor. Today 98% of the hydrogen produced globally comes from fossil fuels because fossil fuels are readily available resource, cost effective and it’s a cleaner alternative to coal. However, producing hydrogen from fossil fuel is not a sustainable option to meet the 1.5 deg C climate goals set in the Paris agreement. Green hydrogen uses renewable energy to produce hydrogen with an end-to-end carbon free process. The emissions produced in green hydrogen production are net zero, which makes green hydrogen a clean fuel of the future. Green hydrogen will play a major role in replacing fossil fuel and help to achieve decarbonization globally.

Green hydrogen is produced using renewable energy to separate water molecules into hydrogen and oxygen using an Electrolyzer. The Electrolyzer splits the hydrogen atoms from the oxygen atoms. After an Electrolyzer creates the hydrogen by splitting water molecules, the hydrogen can then be stored and used whenever energy is needed. Hydrogen can be used as a gas in turbines or stored in fuel cells to produce reliable, clean electricity without any pollution.

On a mass basis, hydrogen has nearly three times the energy content of gasoline—120 MJ/kg for hydrogen versus 44 MJ/kg for gasoline. On a volume basis, however, the situation is reversed, liquid hydrogen has a density of 8 MJ/L whereas gasoline has a density of 32 MJ/L.

Hydrogen has been proven safe from decades of use. It is already produced, stored, and transported in large quantities and has been used in many industrial applications over the years.

Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks. Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C. Hydrogen can also be stored on the surfaces of solids (by adsorption) or within solids (by absorption).

Hydrogen can be stored at the site or transported from a central storage location to other power plants or off-takers in other industries. Today, hydrogen is transported from the point of production to the point of use via pipeline and over the road in cryogenic liquid tanker trucks or gaseous tube trailers. Pipelines are deployed in regions with substantial demand (hundreds of tons per day) that is expected to remain stable for decades. Liquefaction plants, liquid tankers, and tube trailers are deployed in regions where demand is at a smaller scale or emerging. Demonstrations of hydrogen delivery via chemical carriers (e.g., in barges) are also underway in large-scale applications, such as export markets.
