Hydrogen, CCS and fossil gas projects overrun and exceed budget, while wind and solar get built on time and under budget

Jeva Lange, reporting for Heatmap:

The average energy infrastructure project costs 40% more than expected for construction and takes nearly two years longer to complete than initially planned, according to a new study of 662 such projects in 83 countries by the Boston University Institute for Global Sustainability, published in the journal Energy Research & Social Science. Nuclear power plants were the worst offenders, with construction costing 102.5% more on average, or $1.56 billion more than expected. Hydrogen, carbon capture and storage, and thermal power plants that rely on natural gas were also among higher-risk infrastructure projects, the study found.

Solar energy and transmission projects, on the other hand, had the lowest investment risks for construction and time costs, and are often completed ahead of schedule and for less than expected, the research found. Wind, similarly, “performed favorably in the financial risk assessment.”
