This array of bolts looks heavy duty, but the impressive part is happening below it. Andrea Klenotiz and other scientists at start-up Lectrolyst were preparing this electrochemical reactor—the stack of plates under the rods—for a demonstration last year. If the electrochemical stack isn’t squeezed tight, the system becomes much less efficient and even leaky. The start-up aims to convert carbon dioxide and other waste carbon oxides to more useful compounds. The two-step process Lectrolyst is currently trying to scale up uses a catalytic system to turn CO2 to carbon monoxide in one reactor, and then another reactor reduces that gas to products like acetate and ethylene, using other catalysts.
