Progress in thermal energy storage technologies for achieving carbon neutrality
C.Y. Zhao, Jun Yan, X.K. Tian, Xinjie Xue, Yao Zhao
AbstractChina is committed to the targets of achieving peak CO2 emissions around 2030 and realizing carbon neutrality around 2060. To realize carbon neutrality, people are seeking to replace fossil fuel with renewable energy. Thermal energy storage is the key to overcoming the intermittence and fluctuation of renewable energy utilization. In th...... hiện toàn bộ
Experimental study on supercritical carbon dioxide gasification of biomass
Chenchen Zhou, Zhiwei Ge, Yu Wang, Fei Shang, Liejin Guo
AbstractWith the excessive use of fossil energy and concern for environmental protection, biomass gasification as an effective means of biomass energy utilization has received widespread attention worldwide. Supercritical carbon dioxide (SCCO2) (T ≥ 31.26 °C, P ≥ 72.9 atm) has the advantages of near liquid density and...... hiện toàn bộ
A blessing or a curse? Can digital economy development narrow carbon inequality in China? Tập 2 Số 1
Congyu Zhao, Jianda Wang, Kangyin Dong, Xiucheng Dong
AbstractThe importance of carbon emissions reduction notwithstanding, the issue of its inequality should also elicit the urgent attention of scholars. This paper first evaluates the carbon inequality between urban and rural areas based on a panel dataset of 30 provinces in China from 2006 to 2019. Then we quantitively investigate the role of digital economy develop...... hiện toàn bộ
Roles of thermal energy storage technology for carbon neutrality
Mingyang Sun, Tianze Liu, Xinlei Wang, Tong Liu, Mulin Li, Guijun Chen, Dongyue Jiang
AbstractIn order to achieve global carbon neutrality in the middle of the 21st century, efficient utilization of fossil fuels is highly desired in diverse energy utilization sectors such as industry, transportation, building as well as life science. In the energy utilization infrastructure, about 75% of the fossil fuel consumption is used to provide and maintain he...... hiện toàn bộ

High faradic efficiency of CO2 conversion to formic acid catalyzed by Cu2O hollow-dices Tập 1 Số 1
Jing Li, Meng Chen, Jingkun Gu, Honglin Wang, Ruoyun Dai, Haozhi Sha, Hongwei Zhu
AbstractCu2O has been intensively studied as an efficient catalyst for CO2 reduction reaction (CO2RR). By various methods for fine-tuning the morphology and surface modification, high selectivity and activity of different products can be achieved. Here, we report a novel Cu2O nanost...... hiện toàn bộ
Techno-economic analysis of converting low-grade heat into electricity and hydrogen
Yanan Zhao, Mingliang Li, Rui Long, Zhichun Liu, Wei Liu
AbstractLow-grade heat recovery has received increasing attention as an essential contributor to improving overall energy utilization efficiency and facilitating the carbon neutrality commitment. Here, we developed a techno-economic analysis model of converting low-grade heat into electricity and hydrogen via the osmotic heat engine (OHE) and power-to-gas facility ...... hiện toàn bộ
Improving the light stability of perovskite solar cell with new hole transport material based on spiro[fluorene-9,9′-xanthene]
Huiming Luo, Zheng Zhang, Ligang Yuan, Jiarong Wang, Bin Li, Sijing Wang, Mojtaba Abdi‐Jalebi, Lei Shi, Wenjun Zhang, Kunpeng Guo, Liming Ding, Keyou Yan
AbstractDevelopment of suitable hole transport materials is vital for perovskite solar cells (PSCs) to diminish the energy barrier and minimize the potential loss. Here, a low-cost hole transport molecule named SFX-POCCF3 (23.72 $/g) is designed with a spiro[fluorene-9,9'-xanthene] (SFX) core and terminated by trifluoroethoxy units. Benefiting from the suitable ene...... hiện toàn bộ
The impact of ESG on financial performance: a revisit with a regression discontinuity approach
Ziwei Xu, Wenxuan Hou, Brian G. M. Main, Rong Ding
AbstractThis study revisits the question of “whether firms are doing well by doing good?”. We examine shareholders-sponsored corporate socially responsible (CSR) proposals related to Environmental, Social, and Governance (ESG) that are voted to pass or fail by a small margin. The adoption of those “close call” proposals is regarded as equivalent to a random assignm...... hiện toàn bộ
