Antora Energy has unlocked a solution to deliver zero-emissions heat and electricity to heavy industry that is more reliable than fossil fuels, and just as cheap, according to Antora Energy CEO Andrew Ponec. “The manufacturing sector—including notoriously hard-to-decarbonize industries like cement, steel, and petrochemicals—accounts for a staggering 30% of global greenhouse gas emissions. Today, there aren’t scalable solutions to clean up the major drivers of these emissions—heat and power from combusting coal and gas,” Ponec says. “Partnering with Breakthrough Energy Ventures, Lowercarbon Capital, and our strong syndicate of other investors brings the resources and know-how to scale up our business and wipe out billions of tons of CO2 emissions per year.”
