Assessing the energy transition in China towards carbon neutrality with a probabilistic framework

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Янв. 10, 2022

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

China’s Energy Transition Pathway in a Carbon Neutral Vision

Engineering, Год журнала: 2021, Номер 14, С. 64 - 76

Опубликована: Окт. 27, 2021

China's energy system requires a thorough transformation to achieve carbon neutrality. Here, leveraging the highly acclaimed Integrated MARKAL-EFOM System model of China (China TIMES) that takes energy, environment, and economy into consideration, four carbon-neutral scenarios are proposed compared for different emission peak times emissions in 2050. The results show will at 10.3–10.4 Gt between 2025 2030. In 2050, renewables account 60% total consumption (calorific value calculation) 90% electricity generation, electrification rate be close 60%. transition bring sustained air quality improvement, with an 85% reduction local pollutants 2050 2020 levels, early yield more near-term benefits. Early attainment extensive deployment over next decade accelerated phasing out coal after 2025. However, it benefits such as obtaining better sooner, reducing cumulative CO2 emissions, buying time other sectors transition. pressure ambitious reductions can transmitted near future, affecting renewable development, service demand, welfare losses.

China’s energy transitions for carbon neutrality: challenges and opportunities

Carbon Neutrality, Год журнала: 2022, Номер 1(1)

Опубликована: Апрель 19, 2022

Abstract The pledge of achieving carbon peak before 2030 and neutrality 2060 is a strategic decision that responds to the inherent needs China’s sustainable high-quality development, an important driving force for promoting ecological civilization constructions. As consumption fossil fuel energy responsible more than 90% greenhouse gases emissions, policies focusing on transition are vital China accomplishing goal neutrality. Considering fact structure dominated by fuels, especially coal, it urgent accelerate low-carbon system in relatively short time, dramatically increase proportion clean future supply. Although has made notable progress past, its path still faces many significant challenges. During process transformation, advanced technologies greater investment will play essential parts this extensive profound systemic reform economy society. In meantime, these changes create immense economic opportunities geopolitical advantages.

ACS Engineering Au, Год журнала: 2023, Номер 4(1), С. 22 - 48

Опубликована: Дек. 1, 2023

This Review provides an in-depth overview of carbon dioxide (CO2) capture, utilization, and sequestration (CCUS) technologies their potential in global decarbonization efforts. The discusses the concept CO2 including conversion to fuels, chemicals, minerals as well biological processes. It also explores different types sequestration, geological, ocean, mineral storage, associated challenges opportunities such regulatory issues public acceptance. highlights integrating CCUS presents case studies successful projects. benefits limitations these are discussed, along with areas for further research development. Overall, this underscores importance CCUS.

A net-zero emissions strategy for China’s power sector using carbon-capture utilization and storage

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Сен. 25, 2023

Decarbonized power systems are critical to mitigate climate change, yet methods achieve a reliable and resilient near-zero system still under exploration. This study develops an hourly simulation model considering high-resolution geological constraints for carbon-capture-utilization-and-storage explore the optimal solution system. is applied 31 provinces in China by simulating 10,450 scenarios combining different electricity storage durations interprovincial transmission capacities, with various shares of abated fossil carbon-capture-utilization-and-storage. Here, we show that allowing up 20% fuel generation could reduce national total shortage rate 9.0 percentages 2050 compared zero A lowest-cost scenario 16% even causes 2.5% lower investment costs network (or $16.8 billion), also increases resilience reducing during extreme climatic events.
