With various countries setting strategic goals for peaking carbon emissions and achieving carbon neutrality, the global demand for clean energy is showing an increasing trend. On the one hand, wind and solar energy, as the two main pillars of renewable energy, are widely promoted due to their clean and low-carbon environmental benefits. However, the intermittency and instability of these two types of energy have become the primary causes of challenges in new energy consumption and grid integration. On the other hand, a large amount of agricultural waste is produced globally each year, and biomass energy has huge potential. However, in our country, agricultural waste cannot be effectively utilized, one of the important reasons is that the transportation of raw materials is difficult, and some power plants opt to pulverize straw before transporting it, but the straw crushing consumes a lot of energy. This article proposes an innovative model: The straw-crushing plant is combined with the wind power station, and the straw is crushed by abandoning wind and light. This collaborative energy storage mode will effectively alleviate the dual problems of new energy consumption and agricultural waste management. This article, through the analysis of relevant data research indicates that provinces represented by Henan, Hebei, and Shandong not only boast abundant straw resources but also lead in total installed wind and solar power capacity. Rough estimates reveal that Henan Province wastes 1.2 billion kWh of wind and solar power annually, while Hebei Province discards 4 billion kWh yearly. This curtailed wind-solar-straw energy storage system can increase renewable energy utilization efficiency by 3–4%. Compared to traditional grid-based crushing methods, it reduces energy costs for straw pretreatment by 30–40% and achieves a 15–20% reduction in carbon emissions over its full lifecycle. This system offers an innovative approach to integrating renewable energy integration with agricultural circular economy development. It holds a certain guiding significance for the field of new energy consumption and storage.
