Application status of renewable energy in chemical production and its utilities system

“Emission peak and Carbon neutrality target” brings new challenges to chemical production. Improving energy supply structure and enhancing energy efficiency are ones of the important ways to solve this problem. With the continuous development and improvement of energy conversion technology and energy storage technology, the utilization level and supply stability of renewable energy are further improved. It has obvious advantages in replacing chemical utilities system mainly based on fossil energy, and is considered as the most promising way of energy supply for a new generation of chemical systems. Based on the technology of renewable energy supply, this paper summarizes the application status of renewable energy in new chemical utilities such as heating, cooling, water supply, power supply and multigeneration system, and highlights the important role of renewable energy in energy saving and emission reduction compared with traditional chemical utilities. The matching status, problems and challenges of renewable energy in chemical utilities are discussed, and its future development is forecasted. The paper points out that the renewable energy chemical public engineering will become an important way to solve the dilemma of chemical environmental protection.
