山东海阳市的丁字湾零碳园区已成为全国首批国家级零碳园区[1]，标志着这一传统毛衫制造基地成功转型为清洁能源与未来产业的集聚地。园区通过核能综合利用、海上风电、商业航天等产业的梯次布局，正在重构其产业体系，带动区域经济向零碳方向发展。
核能已成为园区清洁能源体系的核心支柱[1]。两大核电基地规划建设17台机组、采用4种堆型，年发电量约1500亿度[1]。园区已形成强大的核能供热能力，当前年产超百万吨核工业蒸汽，远期供汽能力将突破6200万吨[1]。核工业蒸汽成本约200元/吨，相比生物质蒸汽可降低30%以上[1]。国家电投山东核电与清华大学于2019年联合建设的"水热同产同送"技术示范工程奠定了这一优势的基础[1]。园区的全国首个商业化核能供暖工程"暖核一号"已稳定运行7年，为海阳、乳山两地40万居民提供零碳热源[1]。
在新能源方面，园区已建成三座海上风电场，总装机容量达110万千瓦，规划进一步建设150万千瓦[1]。商业航天产业同样表现亮眼，东方航天港已累计将164颗卫星送入预定轨道[1]，并于2026年7月22日完成第26次海上发射，成功发射"引力一号"遥四运载火箭[1]。园区拥有国内唯一的海上商业发射母港[1]。
产业生态的完善正在加速推进。2026年6月，中德零碳热力产业园战略合作协议正式签署，规划连片工业用地3480亩[1]。同月，西门子高层赴海阳考察，对园区的核能零碳热力资源表示高度认可[1]。这些合作进展表明，丁字湾零碳园区正成为吸引国际高端产业落户的新平台。
Haiyang's Dingzi Bay Zero-Carbon Industrial Park has been selected as part of China's first batch of national-level zero-carbon zones as of the end of 2025 [1]. The park represents a dramatic industrial transformation, shifting from traditional sweater manufacturing to clean energy production and commercial aerospace, anchored by a tiered clean energy infrastructure that integrates nuclear power, offshore wind, and space technology.
The park's energy backbone consists of two major nuclear bases planned to house 17 reactors of four different types, with an annual power generation capacity reaching approximately 1,500 billion kilowatt-hours [1]. The facility currently possesses an annual nuclear-powered steam production capacity exceeding one million tons, with future capacity projected to exceed 62 million tons [1]. Nuclear steam supplied at approximately 200 yuan per ton represents more than 30 percent savings compared to biomass-generated steam [1]. Three offshore wind farms have been completed with a combined installed capacity of 1.1 million kilowatts, with plans to expand to 1.5 million kilowatts [1]. The park also hosts China's only commercial maritime rocket launch facility, where the Eastern Aerospace Port achieved its 26th sea-based launch in July 2026, successfully deploying the Gravity-1 carrier rocket on its fourth mission, and has cumulatively placed 164 satellites into designated orbits [1].
A landmark achievement in district heating came through the commercial-scale nuclear heating project "Warm Nuclear One," which has operated stably for seven years and provides zero-carbon heat to 400,000 residents across Haiyang and Rushan [1]. This technology, jointly developed in 2019 by State Power Investment Corporation's Shandong Nuclear Power and Tsinghua University as a "dual-product synchronized transmission" demonstration project, marked a breakthrough in nuclear district heating [1]. International interest in the park's capabilities grew when Siemens executives visited Haiyang in June 2026 and endorsed the Dingzi Bay park's nuclear energy and zero-carbon thermal resources [1]. The same month saw the formal signing of a strategic cooperation agreement for the Sino-German Zero-Carbon Thermal Industry Park, designating 3,480 contiguous acres for industrial development [1].
