This is not correct. Per the DAC literature I've seen, the fully burdened energy cost to capture a ton of CO2 is around 12 MWh. The numbers you provided appear to violate the laws of thermodynamics on their face, whereas the 12 MWh number does not. The 250kWh number likely only accounts for the operational energy requirements, not the fully burdened energy requirements of creating the consumable inputs.
