The transition to 100% renewable energy systems will require a more integrated energy system. Connecting the electricity sector to transport is one of the major challenges in this transition, especially for long-distance and heavy-duty transport. Hydrogen is one potential solution to this challenge, by either using it directly in vehicles or indirectly via the production of synthetic fuels. Electrolysers are necessary to convert electricity to hydrogen and so they will have an essential role in the future smart energy system. However, at present there is a lot of uncertainty in relation to the current and forecasted development of electrolysers. The aim in this report is to reduce this uncertainty by gathering and aligning current knowledge in relation to the technical and economic potential of electrolysers. The results highlight existing and forecasted costs and efficiencies for alkaline, polymer electrolyte membrane (PEM), and solid oxide (SOEC) electrolysers between 2012 and 2050. These inputs can be usedfor analysing energy systems that include electrolysers.
