GREEN HYDROGEN COST REDUCTION In the absence of such clear policy statements, including on the production pathway for hydrogen (i.e. electrolysis or fossil fuels), the lack of certainty of the demand for electrolysers and additional renewable power generation will slow down the growth of the green hydrogen sector, which is already very ambitious in absence of supply bottlenecks. Figure 3. 300 250 200 150 100 50 0 Electrolyser capacity comparison between national strategies and IRENA’s scenarios for 2030. 2020 2030 - Strategies 2030 - Planned Energy Scenario 2030 - Transforming Energy Scenario Based on IRENA analysis. The fulfilment of the strategies announced so far would mean going from around 0.2GW of water electrolysis today to about 85 GW in 2030 (see Figure 3). This represents an annual growth rate of almost 83% per year. As a reference, solar photovoltaic (PV) almost achieved such a pace in 2008-2011, but did so with a trained workforce in place and policy support (feed-in tariffs), while also being easier to install than electrolysers. This means that investments need to rapidly materialise to allow scale-up of electrolyser manufacturing capacity. A few selected hydrogen strategies are highlighted here, in particular those with a clear focus on electrolysers scale-up. For a comprehensive overview of hydrogen policies in place and recommendation for hydrogen policy development, as well as a number of insights into strategies to accelerate its development, refer to previous IRENA reports (IRENA, 2019a, 2020c). Australia: National hydrogen strategy sets a vision for a clean, innovative, safe and competitive hydrogen industry, with the aim of positioning it as a major player by 2030. The strategy outlines an adaptive approach that equips Australia to scale up quickly as the hydrogen market grows. The strategy includes a set of nationally coordinated actions involving governments, industry and the community. Australia has adopted eight international standards to shape its hydrogen future, as it bids to use the fuel to enhance energy security and build a billiondollar export industry. The rules have the potential not only to support the safety of users – with guidance on storage, transport and refuelling – but also to facilitate international trade, as the nation aims to assume a major role 22 Electrolyser capacity (GW) Gap to be filledPDF Image | GREEN HYDROGEN SCALING UP ELECTROLYSERS
