16 March 2022, University of Wollongong and HYSATA "...overall electrolyser system has been designed
for ease of manufacturing, scaling and installation, delivering 95 percent overall system efficiency, compared to 75 percent or less for existing electrolyser
technologies. For hydrogen producers, this will significantly reduce both the capital and operational costs to produce green hydrogen."

15 March 2022, Nature "A high-performance capillary-fed electrolysis cell promises more cost-competitive renewable hydrogen."
"...a unique concept of water electrolysis is introduced, wherein water is supplied to hydrogen- and oxygen-evolving electrodes via capillary-induced transport along a porous inter-electrode separator,
leading to inherently bubble-free operation at the electrodes. An alkaline capillary-fed electrolysis cell of this type demonstrates water electrolysis performance exceeding commercial
electrolysis cells, with a cell voltage at 0.5A cm−2 and 85 degC of only 1.51V, equating to 98% energy efficiency, with an energy consumption of 40.4 kWh/kg hydrogen (vs. ~47.5 kWh/kg in
commercial electrolysis cells). High energy efficiency, combined with the promise of a simplified balance-of-plant, brings cost-competitive renewable hydrogen closer to reality."

01 March 2022, Science Direct "Dedicated large-scale floating offshore wind to hydrogen: Assessing design variables in proposed typologies."
"Highlights: 1. Offshore hydrogen pipelines are economical for large and distant farms.
2. Decentralised offshore typology is flexible in operation and facilitates expansion.
3. Commercial electrolysers need no pre-requisite modifications on a floating turbine.
4. Centralised offshore typology is preferable for large deep-water farms.
This paper considers dedicated large-scale floating offshore wind farms for hydrogen production with three coupling typologies;
(i) centralised onshore electrolysis,
(ii) decentralised offshore electrolysis, and
(iii) centralised offshore electrolysis.
The typology design is based on variables including for: electrolyser technology;
floating wind platform; and energy transmission vector (electrical power or offshore hydrogen pipelines)."
