Apex is the site of the state’s newest public pump for biodiesel fuel, a renewable energy resource that is making inroads in the Triangle but is still hard to find in most of the state.
The biodiesel pump at Crown Express Mart on East Williams Street, which opened to the public in July, is the sixth biodiesel pump in the Triangle and only the 14th statewide.
The pump dispenses the B20 blend, which means that 20 percent comes from recycled cooking grease, oil and fats. Existing diesel engines can use B20 without modification.
As of Friday, the B20 blend at Crown Express Mart costs $3.89 a gallon, compared with $3.94 a gallon for regular diesel fuel.
The Triangle has more biodiesel pumps than anywhere in the state, with three in Raleigh, two in Durham and now one in Apex. The regional runner-up, Asheville, has three pumps.
