The International Energy Agency (IEA) report released on Friday said that China has taken the lead on electrolyser deployment after a slow start. China will control half the world’s installed capacity of electrolysers for producing low-carbon hydrogen by the end of 2023.
The country’s installed electrolyser capacity has jumped significantly in recent years and is expected to reach 1.2 gigawatts, 50 per cent of the global capacity, after having accounted for just 10 per cent of the global capacity in 2020.
Electrolysers are devices used for the industrial separation of hydrogen and oxygen within water molecules, using electricity obtained through renewable energy sources such as solar, wind or nuclear.
With the green energy transition underway, electrolysers are becoming essential to replace traditional methods of producing industrial hydrogen.
The production of low-carbon hydrogen could reach 38 million tonnes by 2030 as long as all projects that have been announced are implemented, the IEA said.
But the IEA is concerned about rising equipment costs due to inflation which are putting projects at risk and reducing the impact of government support for deployment. Several projects have revised their initial cost estimates upwards by up to 50 per cent.
Low-emission hydrogen accounted for less than one per cent of the world’s demand in 2022, it said, meaning hydrogen use accounted for 900 million tonnes of equivalent carbon dioxide emissions.
