If the electricity is from a coal - or gas-fired power plant, then there are still carbon emissions from that vehicle's use.

Next is the cost of as much as $10 billion and five years to build each reactor, compared with about $1 billion for a natural gas-fired power plant.

The accurate measurement of oxygen content in flue gas of coal-fired power plant has significant meaning for the realization of combustion system's closed-loop control and optimization running.
