Construction begins on Neo Orbis; fuel cell vessel with sodium borohydride hydrogen carrier

Green Car Congress

With the keel laying, construction has begun at Next Generation Shipyards in the Netherlands of Neo Orbis , a 20m fuel-cell hybrid port vessel using sodium borohydride as a solid-state hydrogen storage medium. The then DaimlerChrysler used Millenium Cell sodium borohydride it its Natrium fuel cell concept car, introduced in 2001.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C.

DOE awards Cummins $5M for automation of electrolyzer cell and stack assembly

Green Car Congress

Proton exchange membrane (PEM) electrolyzers use a solid polymer electrolyte, and alkaline electrolyzers use an electrolyte solution, such as potassium hydroxide or sodium hydroxide mixed with water. Following successful development, the automation concept should enable more than 100 MW of electrolyzer production capacity.

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

The circulating seawater in the open-cathode system results in a continuous supply of sodium ions, endowing the system with superior cycling stability that allows the application of various alternative anodes to sodium metal by compensating for irreversible charge losses. an alloying material), in full sodium-ion configuration.

ARPA-E awarding $39M to 16 projects to grow the domestic critical minerals supply chain

Green Car Congress

First, an electric potential will be applied to water to simultaneously produce acidity and alkalinity. Travertine will develop the design basis for a 1 ton/day CO 2 removal system to demonstrate the technical feasibility and commercial viability of this concept, taking it from proof-of-concept to field-ready.
