"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."

"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."

"The material is something of a wonder ingredient and can be used in water purification, to preserve produce, to promote plant growth, as a flame retardant in fabrics, and in pharmaceuticals and cosmetics. It offers a safe alternative to toxic chemicals, metals, petroleum products and pesticides used in industry."

"Starting over a decade ago, the institute set up hundreds of sunlight sensors across the city state and began continuously measuring irradiance, the amount of sunlight that makes it to Earth as clouds come and go. Those measurements now constitute a massive data record that researchers, and Singapore power generators and grid operators, use to predict solar power output five minutes to seven hours ahead."

"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."

"Methane is much more potent than is carbon dioxide, in terms of its trapping atmospheric heat, although it also dissipates down faster."

"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."
