„We examine the possibility of producing the relevant sulfur species, SO2[nbsp]or SO3, by in situ conversion from elemental sulfur onboard an aircraft. We provide a first‐order engineering analysis of an open cycle chemical plant for in situ sulfur to sulfate conversion using a Brayton cycle combustor and a catalytic converter. We find that such a plant could have sufficiently low mass that the overall requirement for mass transport to the lower stratosphere may be reduced by roughly a factor of 2. All else equal, this suggests that—for a given radiative forcing—the cost of delivering sulfate aerosols may be nearly halved.“
