克利尼近日在美国科学杂志《科学美国人》意大利版上撰文指出，构建全球能源互联网有助节能环保和电力普及，意大利也将从中获益。

所谓全球能源互联网，是以特高压电网为骨干网架、全球互联的坚强智能电网，是清洁能源在全球范围大规模开发、配置、利用的基础平台，实质是“智能电网+特高压电网+清洁能源”。

克利尼在文章中介绍，中国２０１５年发出“探讨构建全球能源互联网”倡议，２０１６年又推动成立了全球能源互联网发展合作组织，规划世界共享的技术方案，致力于“以清洁和绿色方式满足全球电力需求”。克利尼说，中国清洁能源投资在全球发挥引领作用，特高压线路建设也稳步推进。

他说，全球能源互联网是在相关领域第一个覆盖全球范围的具体化技术和产业合作方案，旨在实现电力普及，并在２０５０年将全球二氧化碳排放控制在１１５亿吨左右，即减至１９９０年时的一半。

按照全球能源互联网发展合作组织的目标，到２０３０年，北极和赤道能源基地发电的外送规模将达到９２００亿千瓦时，全球清洁能源发电量将占到总发电量的５０％左右；待２０５０年全球能源互联网基本建成时，清洁能源发电量有望占到全球总发电量的９０％。

克利尼还表示，经过数十年的实验和测试，在跨洲等远距离传输方面，特高压技术的优势已逐步显现，不仅传输效率高，还有助环保。不过，实现全球能源互联还需要一个过程，清洁能源的利用和存储技术、海底电缆、智能电网等诸多技术仍有待完善。

Internet of Energy to boost electricity use efficiency, benefit world economy: Italian expert

ROME, Dec. 31 (Xinhua) -- The Internet of Energy could be the key to decarbonizing the world's economy, boosting electricity use efficiency and delivering power to the billions of people worldwide with little or no access to electricity, according to Italy's energy expert Corrado Clini.

Clini, a former environment minister of Italy, made the remarks in an article entitled "the Internet of energy", which was published on the December 2017 issue of Le Scienze, or the Italian edition of the Scientific American.

In the article, Clini hailed the Global Energy Interconnection, a project which is proposed by State Grid Corporation of China and aims to build a global power grid interconnection by 2050 that will optimize power from renewables and transmit renewable electricity in real time between any two given points on the map, regardless of the source plant's location.

Electricity from renewables could be transmitted in real-time between distant points on the planet in a worldwide network of power plants and power lines, he said, adding, "Italy could also benefit from a similar network, as it would drive technological development and become a significant geopolitical factor."

As Clini explained, the Global Energy Interconnection project is based on three pillars. First, the development of supercritical ultrahigh voltage direct current (UHV-DC) lines for the lossless, long-distance transmission of electricity; Second, storage of energy from renewables (thermodynamic solar power, hydrogen, high-capacity batteries); the third, smart grids and energy efficiency in the local distribution.

After decades of experimentation and testing, Clini said, UHV-DC technologies have evolved to a point where they offer significant advantages over AC (alternating current) lines in terms of long-range (including intercontinental) transmission volume and efficiency.

Furthermore, the expert said, UHV-DC lines are environmentally safer since they minimize magnetic fields and reduce the "right of row" of the lines.
