GGBS plant to reduce emissions with hydrogen

A new demonstration unit will replace some of the natural gas used to power a ground granulated black furnace slag (GGBS) plant in Port Talbot, Wales, with green hydrogen.

Building materials supplier Hanson today (11th Feb) shared details of the project, stating that it has collaborated with the Energy Safety Research Institute at Swansea University to look at reducing its carbon emissions in Port Talbot.

To achieve its ambitions, the unit will produce hydrogen through the process of electrolysis, where renewable energy is generated through wind and solar on site and directed into the electrolyser of water splitting device.

The electrolyser can efficiently use the energy to split water into hydrogen and oxygen. The hydrogen is then passed into the burner to enrich the combustion mixture, saving carbon emissions from the burning of natural gas.
