The analysis considers the costs associated with electrolysis for hydrogen production, direct air capture (DAC) for CO2, and the processes of condensation and TEG absorption for producing synthetic natural gas (SNG). The study reveals that SNG costs can be significantly reduced with U.S. tax credits for low-carbon hydrogen production. With an electricity price of 3¢/kWh for water electrolysis and a 45V tax credit, the cost of SNG reaches parity with fossil natural gas (NG). The 45V tax credit enhances the economic feasibility of SNG, making it a competitive alternative to fossil NG .
