Volts How to clean up beer brewing and other low-temperature industries
18 snips
Sep 24, 2025 In a thought-provoking discussion, Richard Hart, from the ACEEE, and Teresa Cheng of Industrious Labs tackle the vital yet overlooked topic of decarbonizing low-temperature industrial heat used in industries like beer and dairy. They explore how electrification, through heat pumps and thermal storage, can transform these sectors. The guests delve into the financial incentives needed for adoption, the impact on grid reliability, and the crucial steps needed to engage stakeholders and shift toward cleaner technologies, making it clear that coordination is key for real progress.

Episode notes
Capital Costs And Installation Drive Gaps
- Upfront capex is the main barrier: heat pumps cost more than gas boilers and installation often matches equipment cost.
- Deployment and scale will lower equipment prices over time.
The Spark Gap Is A Major Policy Barrier
- The 'spark gap'—cheap gas vs expensive electricity—widely hinders electrification, especially in places like California.
- Policy and rate design must address that gap to enable uptake.
Subsidize Early Adopters To Build Market
- Use grants and low-cost financing to de-risk early industrial electrification projects.
- Programs like California's Indigo and Green Bank loans can jump-start adoption.
