With the increasingly serious problems of energy shortage and environmental degradation, countries around world are actively developing safe, environmentally friendly, renewable energy. Biomass has become an ideal substitute for fossil fuels due to its abundant reserves, good performance, zero carbon emissions. This paper discusses importance potential biomass as a source China’s development, mainly including three conversion methods physics, chemistry, biology, seven utilization technologies, such direct combustion, gasification, pyrolysis, five application approaches, power generation, gas fuel, liquid bio-based materials. review systematically analyzes challenges faced by development future direction biomass. The resources should take comprehensive high-value path. China is looking new paths, key measure cope with emission reduction, climate change, ecological environment protection.

The present study aims to develop a novel configuration of hydrogen and electricity co-production based on small modular nuclear reactor (SMR) by synergistically integrating the Vanadium Chloride thermochemical (V–Cl) helium-closed Brayton cycles. For V–Cl cycle, steady-state simulation model is developed for first time in Aspen Plus environment. entire system assessed thermodynamically calculating exergy destruction rate efficiency major components employed different subsections (nuclear power production, clean supporting Rankine compression, storage) plant. Various parametric studies are conducted identify scope improvement evaluate suitable operating parameters that exhibit optimized performance. It found maximum H2 production achieved when VCl4 flow 3.6 kmol/h. A specific 9.63 g/kWh achieved. reduction Deacon reactors responsible highest lowest with value 155.46 kW 37.60 accounting 49 % 11.86 overall within cycle. share from secondary cycle compression train 16.48 %. results show an outlet helium pressure 15 bar, work output electrical peaked 4.6 MW 15.64 respectively. energy efficiencies proposed be 16.94 21.42

Hydrogen is a clean secondary energy source that plays an important role in promoting the region’s low-carbon mix transition. Currently, most of evaluations hydrogen production technologies terms consumption focus on efficiency, and fewer studies have been conducted at level exergy. In this paper, we use life-cycle approach quality coefficient method to assess discuss exergic efficiency three technology routes, namely from natural gas, propane dehydrogenation, green electricity, which were carried out China. gas was found lowest with losses mainly compression process, high-temperature chemical reactions, reduced catalyst activity. Propane dehydrogenation be about 16% more than hydrogen, compression. wind power has highest due electricity required run electrolyzer. By analyzing changes exergy China’s future supply, paper per unit will decrease 9.2 kg SC/kg H2 9.6 2030. The process China further improved as proportion electrolytic water structure increases.
