BMW unit in US is researching whether it can turn landfill gas into hydrogen, which could power the BMW factory in South Carolina.
BMW said Monday the company is working with a team that includes the Gas Technology Institute and the South Carolina Hydrogen and Fuel Cell Alliance. The effort is being funded by the South Carolina Research Authority.
Since 2003, BMW has been using methane gas from a local landfill to power more than half of its plant's equipment.
Two years ago, the company spent $12 million to make that program more efficient, and officials say the effort has reduced BMW's carbon dioxide emissions by 92,000 tons per year.
