Roadmap to carbon emissions neutral industrial parks: Energy, economic and environmental analysis

Abstract This article is devoted to discussing the feasibility and the optimal scheme to implement an electric-thermal carbon emissions neutral industrial park and perform a 3E analysis on various scenarios. A carbon emissions neutral framework of electric-thermal hydrogen-based containing MILP energy optimisation model is constructed. Photovoltaic power generation, electrolysis hydrogen production are considered in the model. There is an optimal scheme for realising carbon emissions neutrality in industrial parks, which will cost a relatively high price and the compromise scheme which can implement low carbon emissions is also worth studying. The results of the real-world case show that the present value of the cost of achieving carbon emissions neutrality is $ 8.61 billion (109). The scheme presents a compromise between environment and economy will cost $3.95 billion while bringing a 61 % reduction in emission compared with the baseline, which relies upon on-grid and natural gas. And the scheme is most affordable when hydrogen energy accounts for 95 %. Finally, in order to verify the generalisation of the roadmap, the analysis method has been applied to other industrial park cases of typical cities around the world, and the feasibility of achieving the carbon emissions near-neutral goal in these areas is evaluated.
