Interchangeability of hydrogen injection in Zhejiang natural gas pipelines as a means to achieve carbon neutrality by Tong, Sirui, Li, Xiang, Sun, Shien, Tu, Chengxu, Xia, Xufeng

“…The blending of hydrogen gas into natural gas pipelines is an effective way of achieving the goal of carbon neutrality. Due to the large differences in the calorific values of natural gas from different sources, the calorific value of natural gas after mixing with hydrogen may not meet the quality requirements of natural gas, and the quality of natural gas entering long-distance natural gas and urban gas pipelines also has different requirements. …”

Optofluidic modification of commercial fiber for passive cooling by Ong, Wei Bin

“…Developing energy-saving passive cooling method is crucial for achieving COP26’ goal of carbon neutrality and sustainability. Passive radiative cooling in tropical climate (e.g., Singapore, 1.3477N 103.6816E) is challenging due to the high humidity (84% on average), abundant rainfall (~167 days annually), intense solar radiation (up to 1200 W/m2 at daytime with 40% higher UV radiation), and strong downward atmospheric radiation (~20% higher than that of mid-latitude area), which halve the radiative cooling potential; and thus far, there is no report of outdoor daytime sub-ambient radiative cooling under strong solar radiation (power density >1000 W/m2) in tropical climate. …”
