Optimization of a renewable-power-to-methane process integrated with liquid carbon dioxide energy storage |
| 초록 |
Power-to-Methane (PtM) processes directly coupled with renewables play a critical role in the energy transition. Because of the intermittent nature of renewable power supply, operation flexibility of the PtM process is the key point to improve the system efficiency as well as reduce the production cost. In this work, we conduct the optimal design of the Renewable-PtM process in terms of storage sizing and power allocation using surrogate-based optimization. A flexible and continuous Renewable-PtM process with bi-directional grid connection is set as the basis, which is adopted from our previous work. Flexible operation is achieved by adsorbing dispatchable electricity from the grid and delivering peak electricity for load shifting, therefore, cost reduction can be achieved from electricity arbitrage. A system scheduling model is formulated to understand the impacts of storage sizing and power allocation on renewables penetration, grid power output ratio, and methane production cost. ANN-based surrogate optimization is performed to establish the cost-optimal design. The location of Kramer Junction is selected to demonstrate the feasibility and applicability of the system. |
