针对广东省能源发展及碳排放现状进行分析,认为在碳中和目标下,氢能开发利用在保障能源安全及低碳转型中扮演重要角色.广东省氢能利用及产业发展在全国居于领先水平,主要体现在氢能产业链布局已具雏形、氢能推广应用规模领先全国,但同时也存在氢源保障不足、绿氢比例偏低、应用场景有待拓展等问题.结合广东省产业特色及优势,建议采用可再生能源电力电解水制氢、工业副产氢提纯等方式解决氢源问题,并积极探索氢能在工业领域深度脱碳、交通行业低碳转型、天然气掺氢等领域应用发展,减少工业、交通、建筑等领域对化石能源依赖,帮助难以减排领域深度脱碳,助力碳中和目标实现. 相似文献

Dietary spice components ofCurcuma longa andAbroma augusta have been screened for their protective effect against reactive oxygen species induced lipid peroxidation. They have been
found to be efficient antioxidant when administered in combination. The purpose of the study was to investigate the effect
of oral administration (300mg/Kg) of the aqueous extract of turmeric whose active ingredient isCurcumin andAbromine powder as a hypoglycemic agent mixed with diet. The effect of this aqueous extract on blood glucose, lipid peroxidation (LPO)
and the antioxidant defense system in rat tissues like liver, lung, kidney and brain was studied for 8 weeks in streptozotocin
induced diabetic rats. The administration of an aqueous extract of turmeric and abromine powder resulted in a significant
reduction in blood glucose and an increase in total haemoglobin. The aqueous extract also resulted in decreased free radical
formation in the tissues studied.
The decrease in thiobarbituric acid reactive substances (TBARS) and increase in reduced glutathione (GSH), superoxide dismutase
(SOD) and catalase (CAT) clearly showed the antioxidant property of the mixture. It is suggested that these changes initially
counteract the oxidative stress in diabetes however, a gradual decrease in the antioxidative process may be one of the factors
which results in chronic diabetes. These results indicate that the mixture of the two plants have shown antidiabetic activity
and also reduced oxidative stress in diabetes. A combination ofAbroma augusta and Curcuma longa also restored the other general parameters in diabetic animals. The results were statistically analyzed and indicated that
combination of herbal extracts showed better efficacy as compared to individual herbal plant extracts used. 相似文献
