乌克兰撑不住了?特朗普不想管,欧盟只有口头支票?欧洲国家开始清醒,拥抱俄罗斯才能双赢
Sou Hu Cai Jing· 2025-11-06 11:15
据环球时报报道,2025年11月的国际舞台上,俄乌冲突的剧情正上演着极具讽刺的一幕。乌克兰总统泽 连斯基像热锅上的蚂蚁,一天之内密集召见美国、英国、德国等9国代表和北约官员,姿态近乎哀求, 核心诉求只有一个——过冬的能源和保命的防空系统。这个冬天对乌克兰而言不是普通的寒冬,而是关 乎国家能否存续的生死关,民众取暖需要电力,车辆运转需要汽油,国家维持需要煤炭,每一样都是绕 不开的硬刚需。 可泽连斯基盼来的不是雪中送炭,而是欧盟主席冯德莱恩社交媒体上的"口头支票"。这位欧盟最高负责 人言之凿凿承诺"紧急能源援助"和"持续财政支持",却没说清到底给多少能源、拨多少资金,更没提怎 么突破运输瓶颈送到乌克兰。现实比言辞残酷得多,欧洲想给乌克兰输送电力,却卡在特高压输电技术 上——这项能实现远距离大规模输电的关键技术,全球只有中国掌握,欧美根本拿不出解决方案。无奈 之下只能靠移动发电机应急,欧洲从美国高价购买石油炼制燃油,冒着俄军空袭风险运输,途中损耗高 达50%-60%,说白了就是在做亏本买卖,被层层盘剥还落不到好。 编辑 更让乌克兰绝望的是周边国家的冷眼旁观。匈牙利和罗马尼亚的炼油厂刚遭袭击,西方媒体集体沉默, 这两 ...

“特高压技术”美日俄全失败,中国突破核心科技,还定下世界标准
Sou Hu Cai Jing· 2025-10-20 13:58
当我们在东部城市家中轻松打开电灯,驾驶新能源汽车穿梭在街头,或是乘坐高铁奔赴远方时。 很少有人会想到,驱动这一切的电力可能来自数千公里外西部戈壁的风能、高原的太阳能或是峡谷的水 能。 而将这些清洁能源跨越山河送到我们身边的,正是被称为"电力高铁"的特高压输电技术。 这项如今被视作中国"大国重器"的核心科技,曾让美国、日本、俄罗斯等科技强国纷纷折戟。 最终由中国攻克难关,不仅建成了全球规模最大的特高压网络,更主导制定该领域的国际标准。 那么,这项改变中国能源格局的技术,其终极意义究竟何在? 能源困局催生的刚需 中国的能源分布一直存在着鲜明的"先天不均"。 西部和北部拥有全国80%以上的风能、90%的太阳能以及76%的煤炭。 西南地区集中了80%的水能资源,而70%以上的电力消费却集中在工业发达、人口密集的中东部地区。 这种"西多东少"的格局,长期以来都是制约经济发展的瓶颈。 在特高压技术出现之前,中国主要依靠"运煤到东部发电"的模式满足电力需求。 更给东部城市带来了严重的空气污染,当年困扰全国的雾霾问题,就与大量燃煤电厂的存在密切相关。 与此同时,随着全球"双碳"目标的推进,中国迫切需要开发西部丰富的可再生能源 ...

Core Viewpoint - China's electrification rate is projected to exceed 28% in 2024, surpassing major developed economies in Europe and the US, with an expected rate of around 35% by 2030, which is 8 to 10 percentage points above the OECD average [1][2] Institutional Track - The institutional framework is the foundational "invisible base" for China's electrification, with a consistent energy strategy from the 12th to the 14th Five-Year Plan, integrating electrification as a key component of national modernization and aligning with carbon neutrality goals [1][2] Technological Track - Over the past three decades, China has shifted from "exchanging market for technology" to "nurturing technology through scenarios," establishing a robust industrial chain in solar, wind, and battery sectors, and achieving breakthroughs in grid technology, including unique ultra-high voltage transmission and smart grid systems [2][3] Market Track - China boasts the world's largest unified electricity market and the largest markets for new energy vehicles, solar, and wind manufacturing, leading to rapid cost reductions; by 2023, the cost of solar power generation fell below 0.3 yuan, and battery prices dropped over 70% in five years, creating a positive cycle of technology maturity, cost reduction, market expansion, and reinvestment [2][3] Global Role Transformation - The leading electrification rate indicates China's transition from energy independence to participating in global energy governance, becoming the largest producer of solar, wind, and battery technologies, and supporting energy infrastructure in developing regions, thus reshaping the value chain [3][4] Economic Globalization - China's technology-driven renewable energy development is breaking traditional oil and gas geopolitical logic, promoting inclusive economic globalization and providing new opportunities for shared development among nations [4] Challenges and Opportunities - Despite leading in electrification, challenges remain, such as enhancing grid flexibility, balancing multiple goals in electricity market reforms, and addressing supply chain risks and carbon tariff barriers; however, these challenges present opportunities for institutional innovation and modern governance in global energy [4]
大批电厂岌岌可危,印度要求中方出口电力设备:欧美多国沉默了!
Sou Hu Cai Jing· 2025-10-06 09:40
Core Viewpoint - Indian private coal power producers are urging the government to relax import restrictions on Chinese coal power equipment, citing potential bankruptcy without such measures [1][3]. Group 1: Industry Challenges - The expansion plans for coal power in India face significant challenges, including domestic resource shortages and high costs, making purchasing equipment from China the "only option" [3]. - Approximately 22 GW of private coal power projects in India are stalled or unlikely to commence due to financial issues, representing 10% of the country's current coal power capacity [3]. - The Indian government is caught in an energy paradox, needing to achieve a target of 500 GW of renewable energy by 2027 while still relying on coal for 72% of its power generation [3]. Group 2: Technological Disparities - Indian power plants face significant operational challenges with domestically produced desulfurization equipment, which has a failure rate three times higher than Chinese equipment and longer maintenance cycles [3]. - China's ultra-high voltage transmission technology reduces power loss to 2%, outperforming India's average loss by 18 percentage points [3]. - The cost advantages of Chinese equipment stem from a complete industrial chain, with costs for components being 50% lower than India's fragmented procurement [3]. Group 3: International Trade and Cooperation - The imposition of a 50% tariff on Indian solar panels by the Trump administration has increased the cost of renewable energy projects in India by 20%, reinforcing the need for energy cooperation with China [4]. - China's supercritical coal power technology, with a coal consumption rate of 256 grams per kilowatt-hour, is 35% more efficient than India's existing units, highlighting the importance of Chinese technology in India's energy landscape [4]. Group 4: Strategic Responses - India may adopt a "stepwise breakthrough" strategy, initially acquiring desulfurization technology through joint ventures before gradually penetrating the renewable energy sector [5]. - The collaboration between China Power Construction and Adani Group on a solar-coal complementary project serves as a test case for this strategy [5]. - The transfer of core technology will likely come with strict conditions, similar to China's approach in Pakistan's nuclear projects, indicating a new balance of "exchanging market access for technology without relinquishing control" [5].
