Academician Zhou Xiaoxin: Development prospects and key technologies of my country's energy and power system under the "dual carbon" goal

In order to explore the application potential and engineering promotion of IEPU, a preliminary economic calculation was carried out using synthetic methanol as an example, considering the following equipment technical specification parameters: using the 300 MW coal-fired power unit that has been fully depreciated, the carbon capture capacity is about 150,000 tons, the photovoltaic power generation capacity is 180 MW, the annual operation time is 1,300 hours, and the power demand of the 140 MW electrolyzer is met. The entire system can achieve an annual methanol production of about 100,000 tons. Under the current foreseeable operating costs of major equipment and product prices, the preliminary technical and economic analysis results show that the initial investment of the project is about 1.086 billion yuan, and the investment recovery period is about 14 years at a discount rate of 10%, and the internal rate of return is about 13.1%.

The economic feasibility of renewable energy hydrogen production and various IEPUs is a key factor restricting their development. It is necessary to further conduct a detailed economic analysis based on various factors of actual projects and related technological advances. The realization of the IEPU concept will promote the integration of different industries in the energy field, which requires breakthroughs and innovations in systems and mechanisms.
