Hydrogen Electrolysis Production

Producing Hydrogen, Safely

The process of producing hydrogen using water and electricity is called electrolysis. Electricity breaks water down into its base elements, hydrogen, and oxygen, in a unit called an electrolyzer. An electrolyzer can range in size from small devices to large-scale, central production facilities. Because electrolyzer components need to be reliable and built for hazardous environments to keep people and property safe, there is high importance to work with an expert supplier equipped with a wide range of measurement, control, and electrical equipment.

Frequently Asked Questions about Renewable Hydrogen

Is hydrogen used in the chemical industry?

Hydrogen is used in the manufacture of two important chemical compounds, ammonia and methanol. Therefore, hydrogen is considered a building block to fertilizer made from ammonia and polymers made from methanol.

Is all hydrogen considered a ‘clean’ fuel source?

Millions of tons of hydrogen are used in the industry. But not all hydrogen produced today can be considered carbon neutral. Blue and green hydrogen are the two key low-CO2 alternatives and that could replace carbon-intensive grey hydrogen, which represents 95% of the hydrogen production today.

What role does automation play in green hydrogen production?

Automation technologies increase the capacity, reliability and efficiency of electrolyzers -- and with them the potential of a green hydrogen economy -- in several ways, from handling fluctuating power loads to measuring and controlling water flow with greater precision to using digital analytics for energy management applications. Automation can also improve safety, equipment lifespan and regulatory compliance while lowering materials and workforce costs.

Can hydrogen help the chemical industry achieve net zero goals?

Hydrogen is not only a key enabler to become net-zero for the industry, but also an important opportunity for chemical companies to generate new sustainable revenue streams. Chemical companies can leverage their strong global assets, interlinked supply chains, existing sales and distribution, and hands-on engineering knowledge to shift to a more sustainable portfolio using cleaner and more sustainable resources.
