Stranded Assets and Sticky Systems: A New Model for China’s Energy Transition

Chinese scientists have developed a hybrid analytical model to tackle one of the most stubborn questions in the global energy transition: what happens to existing fossil-fuel assets when a country pivots decisively toward decarbonization? In a paper published in Energy Policy (Volume 215, August 2026), researchers Jianyuan Li, Mei Sun, and Xiucheng Dong introduce a putty–clay perspective on asset stickiness and stranding within China’s energy system.

The study combines support vector regression with system dynamics modeling to produce a quantitative assessment of how rigid or flexible China’s energy capital stock really is. The putty–clay framework is particularly apt here: capital invested in long-lived energy infrastructure is “clay” once set—hard to reshape, expensive to abandon. The model reveals which assets are most vulnerable to becoming stranded and under what policy or market conditions stranding accelerates.

This matters far beyond academic circles. China is the world’s largest energy consumer and carbon emitter, and its transition trajectory will set the pace and tone for global climate action. The findings offer a decision-support tool for policymakers and industrial planners weighing the cost of early retirement against the risk of continued emissions. For international investors and energy firms, the model provides a structured way to think about portfolio risk in a market where regulatory signals are shifting rapidly. The research underscores that China’s energy transition is not simply a story of renewable build-out—it is equally a story of what gets left behind.

Why it matters:
This research gives investors and energy strategists a quantitative framework to assess which Chinese energy assets face the highest stranding risk. It signals that China is moving beyond simple capacity targets toward a more sophisticated understanding of transition costs and capital inertia.
