Ad Because of economies of scale in pipelines, the costs per vocates of deep injection point out that even in the absence unit of CO2 stored or per unit of hydrogen generated increase of deliberate injection, the oceans already receive a portion as the scale of the hydrogen production system decreases. of the carbon released from fossil fuels because of the conUnit costs vary approximately as the inverse square root of tinuous exchange of CO2 between the atmosphere and the the flow rate.
