Electrochemical direct air capture
Electrochemical cells can capture carbon dioxide from air. Can larger stacks sustain that performance while purifying the gas and keeping airflow resistance manageable?
Electrochemical lithium extraction from geothermal brines
Electrochemical cells can selectively recover lithium from geothermal-like brines. Can industrially made electrodes keep that performance during prolonged exposure to hot, impurity-rich feeds?
Direct seawater electrolysis
Can hydrogen production work reliably in the changing conditions of the open ocean?
Low-iridium PEM electrolysis
Can acidic water electrolysers retain efficiency and long operating life while using much less iridium?
Membrane-distillation wetting control
Can seawater distillation membranes stay productive without letting salt water leak through their pores?
Pure-water AEM electrolysis
An electrolyzer can make hydrogen without circulating caustic solution. Can its catalyst layers keep conducting ions and releasing gas as their polymer binder ages?
