April 26 News Summary: Advancements in Quantum Standards and Hydrogen Storage

Support for Lithography Machine Development: A New National Quantum Standard Established

According to reports from CCTV News, in an effort to overcome critical technological bottlenecks in quantum measurement of optical wavelengths, China’s State Administration for Market Regulation has successfully developed and approved the establishment of a new national optical wavelength quantum standard. This achievement effectively addresses the challenges of traditional single-point wavelength measurement, which suffers from limited range and insufficient precision. As a result, China becomes the third country, following the United States and Germany, to independently develop a multi-wavelength synchronization locking system, achieving an overall technology level that meets international standards.

Commentary: The establishment of this new standard signifies the construction of a next-generation, quantum-based, and systematic framework for optical wavelength measurement, providing essential technical support for fields critical to national technological sovereignty and security, such as high-end equipment manufacturing, BeiDou navigation, fiber optics, next-generation communication (6G), and quantum sensing. The series of optical wavelength measurement methods proposed by the team will offer a comprehensive solution for the national integrated circuit industry, facilitating applications in semiconductor manufacturing, particularly for chips produced using 5nm processes and below. Additionally, it will provide nanometer-level wavelength calibration for advanced equipment like EUV lithography machines, addressing key barriers and promoting the development of domestic high-end lithography technology and measurement instruments. Relevant A-share concept stocks include Dingyang Technology (688112) and Tianao Electronics (002935).

Breakthrough in Hydrogen Storage: First Million-Cubic-Meter Salt Cavern Hydrogen Storage Project Launched

As reported by Xinhua News, on April 25, China’s first million-cubic-meter salt cavern hydrogen storage demonstration project officially commenced operations in Pingdingshan, Henan Province. This marks a new phase in the industrialization of China’s hydrogen energy sector, covering the entire hydrogen supply chain from production to storage, transport, and usage. Academician Yang Chunhe of the Chinese Academy of Engineering stated at the launch ceremony that this project fills a significant gap in large-scale salt cavern hydrogen storage technology in China, representing a breakthrough from concept to implementation.

Commentary: Compared to high-pressure gas storage (using cylinders) and liquid hydrogen storage, salt cavern hydrogen storage is regarded as the most effective solution for large-scale, long-term energy storage. Its advantages are clear: it offers enormous capacity at low costs and high safety. Unlike batteries, which can only store energy for short periods, salt caverns can store hydrogen like an “underground natural gas reservoir,” allowing for energy balance across seasons by storing hydrogen during peak renewable energy production and retrieving it during dry or windless periods. Salt cavern hydrogen storage is expected to become a cornerstone of national energy security, capable of absorbing unstable green electricity from the western regions and transporting hydrogen through pipelines, even enabling hydrogen blending with natural gas to provide deep decarbonization solutions for industries and transportation.
