First U.S. utility scale offshore wind farm will cut Massachusetts customer bills by $1.4 billion

It’s also lower than the wind industry expected and shows that offshore wind can be a competitive source of clean energy as costs continue to come down.“That’s pretty shocking for us,” said Tom Harries, a wind analyst at Bloomberg NEF. “I think the wider industry expected much higher prices. The repercussions of this are it will probably awaken a lot of other coastal states to the value of offshore wind.”As prices continue to fall, offshore wind is expected to grow by 16 percent annually through 2030, driven by installations in the U.K., Germany, Netherlands and China, according to BNEF. The U.S. is a latecomer to the market, and early projects may cost more than those in Europe, in large part because developers will need to import components for the massive offshore structures, which can be as big as 600 feet (183 meters).With Vineyard Wind, the U.S. is starting to close the gap, Harries said. While offshore wind is still more costly than onshore wind and solar, it offers other advantages, notably that the turbines will generate power in the winter when prices are high.Federal tax credits and a long-term power-purchase agreement were part of the equation that helped the wind project “offer an attractive price to the benefit of consumers,” Lars Thaaning Pedersen, chief executive officer of Vineyard Wind, said in a statement.“The general consensus was that it would take a while for new markets to reach levels we’ve seen in Europe and the U.S. seems to be doing this pretty fast,” he said.

NPD Analyses Norwegian Shelf Seabed Minerals

first_imgThe Norwegian Petroleum Directorate has conducted a chemical analyses of sulphides and manganese crusts from the Norwegian shelf and revealed that the sulphides contain a high content of copper, zinc and cobalt.The sulphis contains mostly contain iron, but also have a relatively high content of copper (up to 14 per cent in some samples), zinc (3 per cent) and cobalt (less than 1 per cent).These are important metals as society moves towards increasing electrification. They are also in demand from the industrial sector.The content of metals in sulphides and manganese crusts from the Norwegian shelf is higher than what is found in samples from other parts of the world.On the Norwegian continental shelf, it is a known fact that seabed minerals occur in the deeper parts of the Norwegian Sea.The Norwegian Petroleum Directorate has been assigned the task of mapping the extent of such seabed minerals, and systematizing data from the collected samples. Several occurrences of sulphides and manganese crusts have been proven, most recently during the NPD’s voyage in the summer of 2018.The sulphides were found along the volcanic Mohns Ridge between Jan Mayen and Bjørnøya. Manganese crusts have been proven in several locations along the Vøring Spur and around Jan Mayen.The manganese crusts in the Norwegian Sea fall into two groups. One of these contains around double the amount of REE – Rare Earth Minerals, as compared with samples from the Pacific Ocean and the rest of the Atlantic Ocean.The other group has lower concentrations. Both groups contain substantially more lithium (20-80 times) and scandium (4-7 times). All of these elements are metals that are important in the green transition.last_img read more
