Comparison of thyristor and insulated-gate bipolar transistor -based power supply topologies in industrial water electrolysis applications
(Elsevier, 14.02.2021)The demand for green hydrogen is growing as the increasing production of pure hydrogen can no longer be based on fossil hydrocarbons. As water electrolysis would move from niche to a significant consumer of emission-free ... -
Power quality and reactive power of water electrolyzers supplied with thyristor converters
(Elsevier, 28.03.2020)Industrial water electrolyzers apply direct current in kiloampere ranges. Therefore, rectifiers are typically based on thyristors despite the high amplitude current fluctuation excited by the rectifier. This paper studies ... -
Power quality estimation of water electrolyzers based on current and voltage measurements
(Elsevier, 23.12.2019)The ripple of the supplied direct current has a significant effect on the energy efficiency of the water electrolyzer cell. Hydrogen production is defined by the current mean value, but current harmonics generate additional ... -
Power-to-X technology using renewable electricity and carbon dioxide from ambient air: SOLETAIR proof-of-concept and improved process concept
(Elsevier, 15.10.2018)This work demonstrates hydrocarbon production directly from water, solar energy, and air—called SOLETAIR. The plant includes direct air capture (DAC) of carbon dioxide, hydrogen production by water electrolysis, and two-step ...
