Pathways to decarbonisation | Hydrogen

Clean hydrogen provides a crucial pathway to help decarbonise hard-to-abate sectors, making it important to accelerate its deployment across industries.

Despite hydrogen’s potential to help decarbonise the energy system, much work remains to ramp up its production. In this instalment of our Pathways to decarbonisation series, we look at the ways in which hydrogen can help accelerate the net-zero transition for high-emitting and hard-to-abate sectors.


The state of play

Although green hydrogen has the potential to enable the decarbonization of our energy system, the global clean hydrogen projects currently slated would collectively produce only 44 MtH2eq by 2030, a quarter of predicted global demand. Although more than 130 countries (representing 88% of global carbon emissions) have published national hydrogen strategies, accelerating the deployment of clean hydrogen will still require the development of a viable business case, the creation of a foundation for climate-oriented market structuring, and a focus on building long-term resilience.

The way forward

There are several steps the industry can start taking to help achieve net-zero emissions, such as replacing existing grey hydrogen production with green or blue hydrogen; using hydrogen as energy in addition to feedstock; and making green hydrogen more financially advantageous relative to grey alternatives.

To achieve these aims, the hydrogen industry can begin by fostering consolidated voluntary demand, championing the development of synchronised global regulations, supporting the maturation of required technologies, heightening focus on asset reuse and infrastructure, and engaging in cross-industry collaboration.
