Risk Assessment of Zero-Carbon Hydrogen Energy Storage Systems

Research conducted by investigators from Qingdao University of Technology in Qingdao, People's Republic of China, has made significant strides in the field of renewable energy, focusing on the risk assessment of zero-carbon hydrogen energy storage systems. At present, the world's energy is shifting towards completely sustainable development, and hydrogen energy has attracted much attention due to its abundant reserves, clean, and low-carbon properties. Hydrogen energy storage systems coupled with renewable energy have become a research hotspot in this field. However, researchers have encountered investment and construction problems, which hinder the process of achieving full sustainable development.

Key Takeaways:

• Researchers from Qingdao University of Technology have established a new risk evaluation index system for hydrogen energy storage systems, considering the conversion of renewable energy (RE) to electrical energy and then to hydrogen energy.
• The new index system considers the ambiguity and uncertainty of information as well as the risk attitude of decision-makers in the evaluation process.
• Sensitivity analysis and comparison analysis have been used to optimize and make the new evaluation model reliable.
• The research concluded that the overall risk of the hydrogen energy storage system is moderate, with key risks including hydrogen embrittlement, RE resources, cell efficiency and durability, and system reliability.
• Management decision-makers can take preventive measures to ensure the stable operation of the hydrogen energy storage system.
• The research has been peer-reviewed and published in the International Journal of Hydrogen Energy.

Statistics:

• The overall risk of the hydrogen energy storage system is 0.4868.
• Hydrogen embrittlement, RE resources, cell efficiency and durability, and system reliability are identified as key risks.
• The research used sensitivity analysis and comparison analysis to optimize the new evaluation model.
