Abstract Renewable energy future from energy coupling perspective is analysed by using global energy system model. Energy system with high renewable share is examined by four scenarios differentiated by biomass potential and electric vehicle market share. For comparison, business-as-usual scenario with emission fees but without non-renewable energy exclusion is used. In renewable scenarios non-renewable energy sources are phased out by high tax for year 2050 and letting model find cost-optimal path from 2010 to 2050. Results indicate that high renewable share poses major changes in each energy system sector, especially in power generation, industry and transportation. Substantial biomass utilisation is required, and increased electrification of energy system, especially in industrial sector, is necessary with high penetration of solar and wind power. Solar photovoltaics (PV) reaches globally 39–44% share in primary energy and 75% share in electricity generation since positive development of PV technology directs especially power generation in Asia to solar power. This requires high capacity of power-to-x technologies, which use electricity to produce synthetic fuels used in industrial and transport sectors, and electricity storages. Transition to renewable energy system mitigates CO2 emissions by 90% from 2010 to 2050, even though the issue of non-CO2 greenhouse gas emissions remain.

全球能源系统中高可再生能源份额的跨部门效应

摘要 利用全球能源系统模型,从能量耦合的角度分析了可再生能源的未来。根据生物质潜力和电动汽车市场份额区分的四种情景,对具有高可再生能源份额的能源系统进行了检验。为了进行比较,使用了排放费但不排除不可再生能源的一切照旧情景。在可再生情景中,不可再生能源在 2050 年被高税收淘汰,并让模型找到 2010 年到 2050 年的成本最优路径。 结果表明,高可再生能源份额给每个能源系统部门带来了重大变化,尤其是在发电方面,工业和交通。需要大量的生物质利用,并增加能源系统的电气化,特别是在工业部门,太阳能和风能的高渗透率是必要的。太阳能光伏 (PV) 在全球一次能源中占 39-44% 的份额,在发电中占 75% 的份额,因为光伏技术的积极发展使亚洲的发电尤其是太阳能发电。这需要高容量的 power-to-x 技术,该技术使用电力生产用于工业和运输部门的合成燃料以及电力储存。从 2010 年到 2050 年,向可再生能源系统过渡可将二氧化碳排放量减少 90%,尽管非二氧化碳温室气体排放问题仍然存在。这需要高容量的 power-to-x 技术,该技术使用电力生产用于工业和运输部门的合成燃料以及电力储存。从 2010 年到 2050 年,向可再生能源系统过渡可将二氧化碳排放量减少 90%,尽管非二氧化碳温室气体排放问题仍然存在。这需要高容量的 power-to-x 技术,该技术使用电力生产用于工业和运输部门的合成燃料以及电力储存。从 2010 年到 2050 年,向可再生能源系统过渡可将二氧化碳排放量减少 90%,尽管非二氧化碳温室气体排放问题仍然存在。
