"Unlike many of the climate-related projects Exxon is undertaking, this plant is highly experimental. Exxon has previously said that its low-carbon businesses like biofuels and lithium-mining need to make double-digit returns. Direct air capture, by comparison, is more of a space-age science experiment for now—one that may pay off or fade away. The company isn’t disclosing how much it’s spending on the project."

"The machines apply electricity to water and split the compound into its constituent elements of hydrogen and oxygen. It’s quite easy to make an electrolyzer at home that generates small quantities of hydrogen. All you need is two pieces of solid metal, some wire, salty water and a source of electricity."

"Or, dreaming even bigger, it could be integrated into an industrial carbon capture plant, which would help cool the plant and also remove harmful pollutants from the air that contribute to human health concerns such as asthma, per the Asthma and Allergy Foundation of America."

"Form’s core product is a grid battery that uses powdered iron for the anode and runs the reduction and oxidation reactions back and forth to charge and discharge. The saying goes that if you wield a hammer, everything looks like a nail; Form’s engineers store energy by reducing iron, so they saw green iron production as another opportunity to apply their energy storage technique."

"The new packaging is predominantly paper- and fiber-based, so it can be recycled easily. It required Google engineers, designers and suppliers to rethink lamination and coatings, box assembly, enclosures and labels, among other factors."

"Bertrand Daru, Amcor's sustainability director, stated to Packaging Gateway: 'This strategic shift means that our customers benefit from the same premium caps and sparkling foils, but with a more sustainable profile that supports their own environmental targets,' signaling a trickle-down positive sustainability impact."
