Tarim desert highway is the longest in the world to go through a flowing desert.Completion of this highway allows vehicles to travel nearly 500 kilometers from the north of the Tarim Basin to the south.Located in the hinterland of the desert with the water-source wells distributed sparsely,the desert is unable to depend on the power grid for 86 water-source wells along the line.Therefore,diesel engines are used for water supply.Under the"dual carbon"goal,Tarim Oilfield kicked off the zero-carbon desert highway demonstration project.The oilfield took advantage of the good solar energy radiation conditions in the desert area to bring the diesel-powered water-source wells under transformation.The power generation-collection of flows-reduction of pressure-power transmission/storage process was adopted to use photovoltaic power and electrochemical energy storage for replacement of diesel consumption.The prevention plants along the highway were irrigated with water pumped by means of green power.The total installed capacity of this demonstration reached 3410 kW and the annual power generation approached 362×104kW·h.Meanwhile,the annual reduction of CO2 emission reached 3254 tons,thus bringing about integration of photovoltaic power generation,sand prevention and solidification,and desert treatment and establishing the cyclic development model of multi-element integration of"power generation on the plate,plantation under the plate,sand control for earth modification and integrated utilization of water sources".The desert highway is entirely brought under zero emission,allowing oil and gas development along the road in harmony with ecological protection.
