“Breaking the Cycle: Aepnus’ Vision for a Sustainable Battery Industry”

Wastewater from these plants emerges laden with sodium sulfate, a byproduct of sulfuric acid and caustic soda, two chemicals used in battery manufacturing, copper refining and other industries. “We can totally create a circular economy around these reagent chemicals,” Bilen Akuzum, co-founder and CTO of Aepnus Technology, told TechCrunch. The two founded Aepnus to modernize the century-old chloralkali process, which splits salts like sodium sulfate back into the acids and bases that created them. “We don’t use any expensive catalysts in our electrolyzers,” Akuzum said. For customers, fully recycling sodium sulfate waste should reduce disposal and material costs.

Bet Evolution: Advanced Manufacturing Needed for the Future of Hydrogen Fuel

In an alkaline electrolyzer, two electrodes are submerged in a solution of alkaline water (usually consisting of a high concentration of potassium or sodium hydroxide). Alkaline electrolysis differs from the other main approach, proton-exchange membrane electrolysis, in a few ways. One of the most important, though, is that alkaline electrolysis doesn’t require expensive exotic metals like platinum. That gives alkaline electrolyzers a cost advantage from the start, one that Evoloh says it builds on with its lower-cost manufacturing. To further trim manufacturing costs, Evoloh uses roll-to-roll printing, a technique pioneered centuries ago by printing presses and more recently used in battery manufacturing.
