Aurora’s global electrolyser database indicates 213.5 GW of projects planned for delivery by 2040, a one-thousand-fold increase from the 0.2 GW operating currently.
Electrolyser project sizes are scaling up very quickly too as the technology and supply chain matures: to date most projects have been between 1-10 MWs. By 2025 a typical project will be 100-500 MWs, typically supplying ‘local clusters’, meaning that the hydrogen will be consumed locally to the facility. By 2030, typical projects are expected to scale up further to 1 GW+, with the emergence of large-scale hydrogen export projects, deployed in countries benefiting from cheap electricity.
Electrolyser project developers are exploring a range of different business models in terms of the power sources they harness, and the end user of the hydrogen produced. Of the projects that state a power source, most will be using wind power, followed by solar, with a smaller number of projects utilising grid electricity. A large portion of the electrolysers indicate that the end user will be industry, followed by mobility.
