In a low carbon economy, hydrogen supply will have to transform from fossil based technologies to technologies such as alkaline electrolysis, proton exchange membrane electrolysis, anion exchange membrane electrolysis and solid oxide electrolysis. Increased demand and interest in these technologies will lead to their further development. To enhance the policy design and investment decisions, experience curves can be calculated to project the technological development. This article provides an overview of the research field by applying a structured literature review. Main findings include that all technologies will have a similar cost range by 2050, with PEM becoming the most economical. For LCOH, a high variability exists, heavily depending on the assumptions made, however most articles agree that considerable cost reductions to below 2.8 \(EUR/kg\) can be achieved. Lastly, it is clear that further research into the field of experience curves applied to electrolysis is necessary to improve the understanding and increase the transparency of results, as well as validate the calculated experience rates.
