中国国家主席习近平于2020年承诺在2060年前实现碳中和,此后中国围绕能源转型的思路发生了巨大转变。
然而,尽管此后中国出台了一系列重大政策,但目前仍不明确什么是新的能源系统,以及中国实现碳中和目标的最有效途径是什么。
我们的最新研究为中国能源转型建立了三种情景模型:一种是中国在2055年前建立净零排放的能源系统;一种是中国在2055年左右实现这一目标;还有一种是推断当前发展趋势的基线情景。
我们发现,将能效措施、终端用能消费电气化和基于各种可再生能源(如太阳能和风能)的低碳电力供应结合起来,可以极大地帮助该国在2055年前实现脱碳目标。
在最高情景下,中国的电力部门到2055年将不使用化石燃料,而一些行业将继续使用少量煤炭和天然气。然而,配备碳捕集与封存技术的生物质发电厂所产生的负排放将对此起到平衡作用。
双碳目标如何改变局势
2020年9月,当习近平开始在联合国大会上发表演讲时,几乎无人预料到中国会发表如此具有开创性的宣言。

他说:“中国将力争2030年前实现碳达峰、2060年前实现碳中和。”
这一政策现在更多地被称为“双碳”目标。
这句话改变了人们对中国能源转型的整体认识。
在此之前,中国在2017年“十九大”上的目标是“要推进能源生产和消费革命,构建清洁低碳、安全高效的能源体系。”
而习近平在2020年的讲话将中国的优先发展从实现“低碳”转变为实现“碳中和”,使能源部门从至少包括部分化石燃料消费,转变为一旦实现碳中和就几乎不给煤炭、石油和天然气留下空间。
要实现这一转变,需要处于中国政策体系和能源系统的利益相关者,如主要发电企业,真正改变思维方式。
中国在宣布碳中和目标后立即开始行动:国务院推出了“1+N”政策体系,其中包括实现“双碳”目标的总体纲领性文件(“1”)和实施该战略的一系列更具体的指导方针和法规(“N”)。
到目前为止,这些政策主要侧重于在2030年之前实现碳达峰。不过,在2060年之前实现碳中和的长期目标始终存在。
国家能源局发布了一份新型电力系统发展蓝皮书。在更广泛的层面上,多个政府部门已提出要为实现碳中和而推动整个能源系统——而不仅仅是电力系统——进行转型。
因此,今天中国能源转型的基础比习近平宣布之前更加坚实和精确。现在的问题是:新型能源系统将是什么样子,中国将如何实现这一目标?
中国能源转型的三种情景
为了回答这些问题,我们的研究模拟了中国能源转型的三种情景:一种是中国在2055年前建立一个净零排放的能源系统;一种是中国在2055年左右实现这一目标;还有一种是推断当前发展趋势的基线情景。
该分析基于一种详细的自下而上的建模方法,同时将“美丽中国”愿景——实现“绿色和高质量增长”的官方倡议——作为转型的指导方针。
在我们的模型中,能源转型的总体战略包括三个紧密相连的行动:
- 提高整个供应链的能源效率;
- 尽可能使终端用能部门电气化;
- 将电力部门转变为以太阳能和风能为支柱的“绿色”、无化石能源部门。
(政府间气候变化专门委员会的最新评估报告显示,这些是将升温控制在1.5°C或2°C的所有全球路径的关键要素。)
遵循这一战略的结果是,中国的能源系统将能够为中国可持续的经济增长提供动能,同时实现净零碳排放、空气质量改善和高水平的能源安全。
在最高情景下,中国的电力系统将从2045年起实现碳中和,整个能源系统将在2055年前实现碳中和。
与今天的情况相比,尽管经济有所增长,但2060年的一次能源消费总量将有所下降。此外,煤炭、石油和天然气将几乎被逐步淘汰,对进口化石燃料的依赖将被消除。
下图显示了2021年中国经济的能流(上图)与2060年在最高情景下的能流(下图)的对比。
在左侧,各版块显示了流入经济的一次能源来源,如煤炭(黑色)、天然气(粉红色)、石油(灰色),以及非化石燃料,如核能(棕色)、水能(深蓝色)、风能(浅蓝色)和太阳能(黄色)。
各版块的中心都显示了一次能源转化为更有用形式的过程,如电力或精炼油产品。化石燃料中所含的大部分一次能源在这一阶段以废热的形式被浪费(“损失”)。
右侧是按部门划分的最终能源用户。
最值得注意的是,化石燃料(尤其是煤炭)是2021年最大的能源来源,而在雄心勃勃的2060年情景(见下图)中,低碳能源则占主导地位。


中国能源转型的三个阶段
我们的研究表明,转型之路将分为三个主要阶段。第一阶段是2030年前的碳达峰。
在此期间,风电和光伏发电的部署将继续增加,同时工业和交通部门的电气化也将取得进展。
然而,就一次能源消费总量而言,煤炭和石油仍将是最主要的初级能源消费。
接下来是“能源革命”阶段,从2030年到2050年。在这一阶段,光电和风电将成为电力供应的主要来源,终端用能部门的电气化程度将大幅提高。
摒弃化石燃料可以最大限度地减少发电和提炼过程中的废热损失。同时,利用可再生能源生产的“绿氢”在工业领域将变得越来越重要。
第三阶段是巩固阶段,从2050年到2060年。脱碳发生在钢铁和化工等难以实现电气化的细分部门,旧的风光发电厂将被新的风光发电厂取代,能源组合中剩余的化石燃料几乎被淘汰。
煤电成为灵活性提供者
虽然中国政府计划从2025年起“逐步淘汰”煤炭,但根据当前的政策方针和市场情况,我们估计在三种情景中,煤电装机都不会迅速消失。
相反,燃煤电厂将逐渐成为保障能源安全和满足电力需求高峰的能力提供者,而不再进行大量发电。
当燃煤电厂达到30年左右的预期寿命时就将被关闭,而不会被新的煤电装机所取代。如下图所示,在我们最高情景中,最后一批煤电厂将于2055年关闭。
图中上半部分显示了2021年至2060年燃煤电厂的装机容量,下半部分显示了燃煤电厂的发电量。


与此同时,在我们的情景中,天然气在电力部门作用有限。这是因为光电和风电可以提供更便宜的电力,而现有的燃煤电厂——加上储能和需求侧响应设施的大规模扩张——足以提供灵活性和调峰能力。
管理由多变的风电和光电主导的电网
依赖光电和风电作为主要电力来源的能源系统,需要采取特殊的灵活性措施促成供需有效匹配。
下图显示了在2055年前实现碳中和的雄心勃勃的情景下,2060年夏季一周内每小时电力平衡的模拟示例。
图中上半部分显示的是供应侧发电量。在白天,光电(黄色)在电力生产中占主导地位,而风电厂(浅蓝)在24小时内都有更稳定的输出。
在傍晚和夜间,储能(紫色)会被释放,水力发电量(深蓝)高于白天。
图中下半部分显示的是需求侧的用电情况。储能(紫色)在白天充电,电动汽车智能充电(蓝色)在一周内提供灵活性。

作为后备电源,电动汽车车网互动发挥着重要作用——其不一定是重要的能源供应商,而是在风电和光电输出有限时,成为必要时可以启用的最后手段。该方案是保证电力系统容量充足的一种经济、高效的方法。
在2055年之前,煤电厂同样可能是电力系统可靠且经济的容量提供者,尽管如前所述,其平均发电量并不高。
从日常调度(管理供需的过程)的角度来看,这种创造灵活性的方式似乎很复杂。然而,一个高效且运作良好的电力市场(包括消费者和生产者)可以做到这一点。
消除各省之间的电力交易障碍、构建全国统一的电力市场,将是实现这一目标的关键因素。
未来远景规划
我们在《中国能源转型展望》(China Energy Transformation Outlook)中的情景对净零排放能源系统的长期未来提供了一系列量化远景规划。
我们对电力系统和其他能源终端用能部门建立了详细的模型,从而可以将这一新能源系统的发展与实现这一转变的政策措施联系起来。
我们研究得出的一个关键结论与上述中国能源转型不同阶段的时机有关。我们的模型表明,成功协调这些阶段至关重要,这样才能在保持能源安全的同时避免对能源基础设施进行不必要的投资。
我们情景中的其他关键推动因素包括扩大电网所需投资、国家电力市场的发展和对能源系统灵活性的支持。
即使有最优的远景规划和从我们的路径中获得的洞见,中国要实现2060年的目标仍有许多需要克服的挑战和障碍。
然而,我们的情景表明,有一些可行且具有成本效益的路径可以在不等待新技术突破的情况下实施。

Analysis: EVs just outsold petrol cars in EU for first time ever
Sales of electric vehicles (EVs) overtook petrol cars in the EU for the first time in December 2025, according to new figures released by industry group the European Automobile Manufacturers’ Association (ACEA).
The figures show that registrations of battery EVs – sometimes referred to as BEVs, or “pure EVs” – reached 217,898, up 51% year-on-year from December 2024, as shown in the chart below.
Meanwhile, sales of petrol cars in the bloc fell 19% year-on-year, from 267,834 in December 2024 to 216,492 in December 2025.

Overall in 2025, EVs reached 17.4% of the market share in the bloc, up from 13.6% the previous year.
(EVs run purely from a battery that is charged from an external source, plug-in hybrids have both a battery that can be charged and an internal combustion engine, whilst regular hybrids cannot be plugged in, they have a smaller battery that is charged from the engine or braking.)
According to ACEA, 1,880,370 new battery-electric cars were registered last year, with the four biggest markets – Germany (+43.2%), the Netherlands (+18.1%), Belgium (+12.6%), and France (+12.5%) – accounting for 62% of registrations.
In a release setting out the figures, ACEA described this as “still a level that leaves room for growth to stay on track with the transition”.
Meanwhile, registrations of petrol cars fell by 18.7% across 2025, with all major markets seeing a decrease.
France accounted for the steepest decline in petrol registrations at 32% year-on-year, followed by Germany (-21.6%), Italy (-18.2%), and Spain (-16%).
Overall, 2,880,298 new petrol cars were registered in 2025, a drop in market share from 33.3% in December 2024 to 26.6%.
Hybrid vehicles, which are entirely fuelled by petrol or diesel, remain the largest segment of the EU car market, with sales jumping 5.8% from 307,001 in December 2024 to 324,799 a year later, as shown in the chart below.
However, cars that can run on electricity – battery EVs and plug-in hybrids – are growing even faster, with sales up 51% and 36.7% in December 2025, respectively.

The registration figures follow the EU’s automotive package, released in December to “support the automotive sector’s efforts in the transition to clean mobility”.
It includes a proposed shift from banning the sale of new combustion-engine cars from 2035 to reducing their tailpipe emissions.
Under the proposals, the EU will target a 90% cut in carbon dioxide (CO2) emissions from 2021 levels by 2035, rather than all vehicle sales having to be zero-emissions.
If approved, the package would require that the remaining 10% of emissions be compensated through the use of low-carbon steel made in the EU or from e-fuels and biofuels.
This would allow for plug-in hybrids (PHEVs), “range extenders”, hybrids and pure internal combustion engine vehicles to “still play a role beyond 2035”.
There has been repeated pushback from the automotive sector in Europe against the introduction of “clean car rules”, which has led to targets being shifted more than once.
For example, the head of Stellantis, one of the largest car manufacturers in Europe, recently claimed that there was no “natural” demand for EVs.
Automakers have argued that EU targets for cleaner cars should be eased in the face of competition from Chinese producers and US tariffs.
ACEA figures show Volkswagen continued to claim the largest market share in the EU, accounting for 26.7% of new registrations in December, up from 25.6% a year earlier.
It was followed by Stellantis, Renault, Hyundai, Toyota and BMW.
EV giant Tesla saw its market share drop from 3.5% in December 2024 to 2.2% in December 2025. Over the course of 2025, the brand saw its market share in the EU fall 37.9% from 2024, following controversy around its owner, Elon Musk.
Meanwhile, Chinese EV brand BYD tripled its market share from 0.7% in December 2024 to 1.9% in December 2025.

For proof of the energy transition’s resilience, look at what it’s up against
Al-Karim Govindji is the global head of public affairs for energy systems at DNV, an independent assurance and risk management provider, operating in more than 100 countries.
Optimism that this year may be less eventful than those that have preceded it have already been dealt a big blow – and we’re just weeks into 2026. Events in Venezuela, protests in Iran and a potential diplomatic crisis over Greenland all spell a continuation of the unpredictability that has now become the norm.
As is so often the case, it is impossible to separate energy and the industry that provides it from the geopolitical incidents shaping the future. Increasingly we hear the phrase ‘the past is a foreign country’, but for those working in oil and gas, offshore wind, and everything in between, this sentiment rings truer every day. More than 10 years on from the signing of the Paris Agreement, the sector and the world around it is unrecognisable.
The decade has, to date, been defined by a gritty reality – geopolitical friction, trade barriers and shifting domestic priorities – and amidst policy reversals in major economies, it is tempting to conclude that the transition is stalling.
Truth, however, is so often found in the numbers – and DNV’s Energy Transition Outlook 2025 should act as a tonic for those feeling downhearted about the state of play.
While the transition is becoming more fragmented and slower than required, it is being propelled by a new, powerful logic found at the intersection between national energy security and unbeatable renewable economics.
A diverging global trajectory
The transition is no longer a single, uniform movement; rather, we are seeing a widening “execution gap” between mature technologies and those still finding their feet. Driven by China’s massive industrial scaling, solar PV, onshore wind and battery storage have reached a price point where they are virtually unstoppable.
These variable renewables are projected to account for 32% of global power by 2030, surging to over half of the world’s electricity by 2040. This shift signals the end of coal and gas dominance, with the fossil fuel share of the power sector expected to collapse from 59% today to just 4% by 2060.
Conversely, technologies that require heavy subsidies or consistent long-term policy, the likes of hydrogen derivatives (ammonia and methanol), floating wind and carbon capture, are struggling to gain traction.
Our forecast for hydrogen’s share in the 2050 energy mix has been downgraded from 4.8% to 3.5% over the last three years, as large-scale commercialisation for these “hard-to-abate” solutions is pushed back into the 2040s.
Regional friction and the security paradigm
Policy volatility remains a significant risk to transition timelines across the globe, most notably in North America. Recently we have seen the US pivot its policy to favour fossil fuel promotion, something that is only likely to increase under the current administration.
Invariably this creates measurable drag, with our research suggesting the region will emit 500-1,000 Mt more CO₂ annually through 2050 than previously projected.
China, conversely, continues to shatter energy transition records, installing over half of the world’s solar and 60% of its wind capacity.
In Europe and Asia, energy policy is increasingly viewed through the lens of sovereignty; renewables are no longer just ‘green’, they are ‘domestic’, ‘indigenous’, ‘homegrown’. They offer a way to reduce reliance on volatile international fuel markets and protect industrial competitiveness.
Grids and the AI variable
As we move toward a future where electricity’s share of energy demand doubles to 43% by 2060, we are hitting a physical wall, namely the power grid.
In Europe, this ‘gridlock’ is already a much-discussed issue and without faster infrastructure expansion, wind and solar deployment will be constrained by 8% and 16% respectively by 2035.
Comment: To break its coal habit, China should look to California’s progress on batteries
This pressure is compounded by the rise of Artificial Intelligence (AI). While AI will represent only 3% of global electricity use by 2040, its concentration in North American data centres means it will consume a staggering 12% of the region’s power demand.
This localized hunger for power threatens to slow the retirement of fossil fuel plants as utilities struggle to meet surging base-load requirements.
The offshore resurgence
Despite recent headlines regarding supply chain inflation and project cancellations, the long-term outlook for offshore energy remains robust.
We anticipate a strong resurgence post-2030 as costs stabilise and supply chains mature, positioning offshore wind as a central pillar of energy-secure systems.
Governments defend clean energy transition as US snubs renewables agency
A new trend is also emerging in behind-the-meter offshore power, where hybrid floating platforms that combine wind and solar will power subsea operations and maritime hubs, effectively bypassing grid bottlenecks while decarbonising oil and gas infrastructure.
2.2C – a reality check
Global CO₂ emissions are finally expected to have peaked in 2025, but the descent will be gradual.
On our current path, the 1.5C carbon budget will be exhausted by 2029, leading the world toward 2.2C of warming by the end of the century.
Still, the transition is not failing – but it is changing shape, moving away from a policy-led “green dream” toward a market-led “industrial reality”.
For the ocean and energy sectors, the strategy for the next decade is clear. Scale the technologies that are winning today, aggressively unblock the infrastructure bottlenecks of tomorrow, and plan for a future that will, once again, look wholly different.
