The backup battery choice you didn’t know you had: natural gas fuel cell

The article discusses the WATT Fuel Cell, a natural gas fuel cell that uses existing home gas lines to generate power, offering a backup solution for homes during outages or to avoid peak energy rates. It's a solid oxide fuel cell that converts natural gas into electricity through a chemical reaction, producing fewer emissions than conventional generators. The WATT HOME system has achieved a 2 kW power rating and is set to launch residentially in 2026, with the first installation occurring in West Virginia. While not zero-emissions, it's considered cleaner than traditional generators and can be a viable option for buildings where solar panels aren't feasible.
