Hydrogen is supplementing natural gas, but critics remain wary
FEB 6, 2023
A public utility is experimenting with blending small amounts of carbon-free hydrogen into natural gas lines in some Minnesota homes, but critics argue the procedure remains largely an exercise in hot air.
As first reported last week by Energy News Network, the Midwest’s CenterPoint Energy company began injecting as much as five percent hydrogen gas into downtown Minneapolis residents’ methane supplies for their homes’ stoves and heaters last summer. After various small modifications at the $2.5 million hydrogen pilot production facility (which was built on a former coal gasification plant), the utility provider is now claiming success. But the lengthy list of overall remaining concerns still makes it unlikely to see green hydrogen mixing compose a large portion of future infrastructures.
