How One Factory Turned Waste Heat Into Free Power
from The Manufacturing Economy with Fexingo: Factories, Industrial Output, and Domestic Production · host Fexingo
Episode 29 of The Manufacturing Economy takes Lucas and Luna inside a $1.2 billion steel plant in Indiana that captures waste heat from its blast furnace to generate 40 megawatts of electricity — enough to cover 15 percent of the mill's total power demand. The hosts walk through the thermodynamics, the four-year payback period, and why the technology, called organic Rankine cycle, has been slow to spread despite being commercially viable for a decade. They also explore how a pair of federal tax credits in the Inflation Reduction Act finally tipped the economics for older mills. Along the way, Lucas and Luna discuss the larger question: if waste heat recovery works this well for steel, why aren't more factories doing it? The episode closes with a look at the Department of Energy's new 'waste heat to power' roadmap and what it means for the next generation of factory retrofits. #WasteHeatRecovery #SteelPlant #OrganicRankineCycle #SteelIndustry #Indiana #BlastFurnace #Decarbonization #IndustrialEfficiency #Manufacturing #Economics #IRA #TaxCredits #DepartmentOfEnergy #PowerGeneration #Reshoring #CleanManufacturing #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
