Solar Builder: Urban Electric Power’s zinc-alkaline batteries win on lower carbon emissions
Urban Electric Power marked National Battery Day (apparently on Friday, Feb. 18 — didn’t you get our card?) by boasting some new carbon emissions test results for its battery versus other battery chemistries.
Boundless Energy Impact Research and Analytics compared Urban Electric Power’s battery — based on the familiar zinc alkaline chemistry of household alkaline cells (e.g. AA) — with lithium-ion, lead-acid, and sodium-sulfur.
“The Boundless Energy analysis showed that the greenhouse gas emissions associated with manufacturing Urban Electric Power batteries are 82% lower compared to lithium-ion batteries, 72% lower compared to lead-acid batteries, and 71% lower compared to sodium sulfur batteries, with a savings of 15,984 tons of CO2-equivalent emissions per US$1 million capital investment in Urban Electric Power batteries. Urban Electric Power’s battery scored a 9.6 out of 10 for overall per-unit impact.”
