In Figure , we also present the payback period for each scenario. Only the first and third scenarios (with flexible systems) are economically viable/feasible, and the corresponding payback periods are 8-10 years. The non-flexible system is not economically viable in any of the scenarios. Specifically, even with an average RTM price in Panhandle, TX (12 USD/MWh, which is 25% lower than the Texas average), the non-flexible system is not viable. This again highlights the importance of being flexible and exploiting price dynamics. The techno-economic analysis focuses on augmenting an existing methanol plant (that embeds an SMR unit) with an electrification unit. The deployment of the electrification unit can reduce the cost of the SMR, and this reduction can be seen as a revenue stream. The SMR cost reduction is obtained via reductions on the use of natural gas, electricity, water, and oxygen. We found that reducing the capacity of SMR by 50% leads to a 131 million USD cost reduction. After considering the operational cost of the electrification units, the annual cost reduction of the first and third scenarios are 62 million USD and 48 million USD, respectively. This implies that, under certain scenarios, the flexible electrification unit can produce synthesis gas at a lower cost than SMR. Specifically, this occurs when the electricity market provides sufficient incentives (sufficiently low average prices and sufficiently high frequency of negative prices). Sensitivity Analysis. We used sensitivity analysis to explore the impact of techno-economic parameters on the viability of the system (see Figure ). We perturb the values of each parameter by 20% and analyze how the payback period changes. We recall that partially replacing SMR with electrolysis can lead to revenue if natural gas prices are high; therefore, the flexible electrification unit has shorter payback periods when natural gas prices are high. This highlights that the methanol process benefits from having a dual system that includes SMR and electrolysis. We also note that the production of oxygen by the electrolyzer can create a revenue stream; as such, the higher the oxygen prices, the shorter the payback period.
