      abstract     = {Water electrolysis is a promising technology for storing
                      surplus energy from intermittent renewable energy sources in
                      the form of hydrogen. The future investment costs of water
                      electrolysis represent one key challenge for a
                      hydrogen-based energy system. In this work, a literature
                      review was conducted to evaluate the published data on
                      investment costs and learning rates for PEM and alkaline
                      electrolyzers from the 1990s until 2017 and the years
                      beyond. The collected data are adjusted for inflation and
                      specified in €2017 per kW-output using the higher heating
                      value (HHV). $R\&D$ efforts have led to impressive cost
                      reductions in the observed period, especially for PEM
                      technology, while cost reductions for alkaline technology
                      have also been decent. The overall spread of the cost
                      estimations in the 1990s was in a range between 306 and 4748
                      €2017/kWHHV-Output. Today's estimations for future
                      investment costs (through 2030) for both technologies are
                      narrowed towards values of 397 and 955 €2017/kWHHV-Output.
                      Higher automation, mass production, larger cell areas,
                      market penetration and technology development will all have
                      a further impact on the investment costs.},
