Abstract A profound transformation of China’s energy system is required to achieve carbon neutrality. Here, we couple Monte Carlo analysis with a bottom-up energy-environment-economy model generate 3,000 cases different peak times, technological evolution pathways and cumulative budgets. The results show that if emissions in 2025, the neutrality goal calls for 45–62% electrification rate, 47–78% renewable primary supply, 5.2–7.9 TW solar wind power, 1.5–2.7 PWh storage usage 64–1,649 MtCO 2 negative emissions, synergistically reducing approximately 80% local air pollutants compared present level 2050. emission time budget have significant impacts on decarbonization pathways, technology choices, transition costs. Early peaking reduces welfare losses prevents overreliance removal technologies. Technology breakthroughs, production consumption pattern changes, policy enhancement are urgently

Hybrid renewable integration, electrification, hydrogenation, spatiotemporal energy sharing and migration, optimisations are necessary roadmaps for the transition towards low-carbon airport transportation systems. In this study, a comprehensive review on sustainable ecosystems with hydrogen-based renewable-grid-storage-flexibility, has been conducted, from perspectives of ecosystem constitutions, supported power supply chain, novel migration paradigms, single multi-objective optimisations, together multi-criteria decision-making approaches. Hydrogenation in jet aircraft systems various advantages, such as lightweight low fuel load, high specific energy, zero CO2 emissions, NOx reduced air pollution, environmental sustainability. Depending different sources, liquid hydrogen (LH2) can be produced by solar wind coastal ocean bioenergy, through chemical technologies water electrolysis power. Synergistic operation between land promote net-zero emissions. Novel interaction frameworks have formulated, inter-city/inter-country trading, compensation uneven distributed resources, penetration renewables. Results showed that characteristics include lightweight, high-energy density, energy-intensive, fast response, safety, stochastic, nonlinear, dynamics. Coastal resources full huge potentials to support systems, off-shore turbines, floating PV panels, current wave converters, tidal stream generators, thermo-electric generators. Research results provide conceptional frameworks, prospects, technical challenges, electrification hydrogenation both sectors, paving path sustainability carbon neutrality.

Decarbonization of the electric power sector is essential for sustainable development. Low-carbon generation technologies, such as solar and wind energy, can replace CO2-emitting energy sources (coal natural gas plants). As a engineering practice, long-duration storage technologies must be employed to manage imbalances in variable renewable supply electricity demand. Compressed air (CAES) an effective solution balancing this mismatch therefore suitable use future electrical systems achieve high penetration generation. This study introduces recent progress CAES, mainly advanced which clean technology that eliminates fossil fuels, compared with two commercial CAES plants at Huntorf McIntosh are conventional ones utilizing fuels. Advanced include adiabatic isothermal liquid storage, supercritical underwater coupled other technologies. The principles configurations these briefly discussed comprehensive review state-of-the-art presented, including theoretical studies, experiments, demonstrations, applications. comparison discussion summarized focus on technical maturity, sizing, capacity, operation pressure, round-trip efficiency, efficiency components, duration, investment cost. Potential application trends were compiled. paper presents reference developing novel makes recommendations research development facilitate their several areas, ranging from fundamentals

To achieve their carbon peak and neutrality target, China’s energy transition is seen as the most important instrument. Despite rapid growth of renewable in China, there are still many challenges. Based on review contemporary literature, this paper seeks to present an updated depiction Chinese context. The potential, status quo, related policy thoroughly investigated. challenges facing development under target analyzed, including enormous urgency pressure, technology, issues. Then, coping strategies proposed guide direction development. Technology paths recommendations presented. This contributes technology developing policymaking by providing a comprehensive, thorough, reliable China.
