💧🇳🇴💧Under the sea: exporting Norway’s hydropower
在深深的海底：挪威出口水力發電
Today testing begins on the North Sea Link, a high-voltage subsea electricity cable spanning the 720km between Britain and Norway. If all goes to plan the link will open later this year, allowing Britain to draw on Norway’s massive hydropower reserves. Norway already supplies power to its neighbours, having exported excess energy under the sea to Denmark and the Netherlands for years. And power doesn’t just flow one way. Last month, Germany’s grid was hooked up to Norway’s through the NordLink connection. This allows Germany to export surpluses of its wind and solar energy, generated on blustery and sunny days, in exchange for a supply of Norwegian hydropower on still and dark ones. Such connections help to ensure that less renewable energy goes unused. But they are not a silver bullet for reducing greenhouse-gas emissions. Even at peak times, Norway will still provide enough energy to power just 5% of British needs and 8.7% of German ones.
連接英國與挪威、長達 720公里的高電壓海底電纜「北海連接 (North Sea Link)」將在今天試運轉。如果順利的話，該電纜預計將在今年底正式啟用，一舉將挪威多餘的水力發電 (之電力) 輸往英國。其實挪威早就長年經由海底電纜將多生產的電力輸送至像是丹麥、荷蘭等鄰國。而這樣的輸電模式並非單向，即在上個月德國電網才透過 NordLink 這條電纜正式嫁接上挪威電網，使得德國可以出口在風大以及日照充足時生產之多餘的風電與太陽能電給挪威，以換取挪威為其在風勢較小與陰天時供應水電。這種 (電網的) 連接有助於確保降低再生能源的浪費。但它們並非減少溫室氣體排放的萬靈丹。即使在供電的高峰時段，挪威仍僅將提供足夠的能源來滿足英國 5%的需求和德國 8.7%的需求。
