‘Never let good hydrogen go to waste’, they must have thought at INEOS. The British chemical group wants to make better use of its hydrogen gas, which is released as a byproduct when making chlorine and caustic soda. To do so, they are investing EUR 10 million to build a hydrogen boiler at the Flanders-based plant of Inovyn, a subsidiary, scheduled to be operational by the end of 2024.

Addressing the great escape

Inovyn's chlorine plant in Antwerp releases high amounts of hydrogen during the electrolysis process, in which a mixture of water and salt is energized to make chlorine and caustic soda. Much of that hydrogen is supplied to nearby company Bayer and the neighboring gas specialist Air Liquide, which operates a hydrogen network linking industrial customers. But about a third of its hydrogen gas still escapes into the atmosphere and goes to waste.

Under steam

To minimize the energy waste, INEOS will soon use the surplus hydrogen itself. The British group revealed its plans to build a hydrogen boiler at Inovyn’s plant, a total investment of EUR 10 million. The hydrogen boiler will replace steam boilers at neighboring countries that now run mainly on natural gas.

With a capacity of 22 megawatts, the hydrogen boiler will be able to produce about 25 tons of steam per hour, covering 65% of the Inovyn plant's needs.

'By reusing hydrogen, we can produce over half of our own steam, indirectly reducing our CO₂ emissions.

Green alternative to fossil raw resources

With gas prices going through the roof, it is expected that reusing surplus hydrogen will become common practice in the near future. In 2022, for example, chlorine producer Vynova installed two steam boilers that run on the hydrogen released as a residual product from the production process rather than on natural gas.
