China to build world’s largest floating solar power plant in major commitment to renewable power

Project beingA�built in eastern province of Anhui and will cost A?113 million

A unit ofA�ChinaA�Three Gorges Corp. is building a 1 billion yuan (A?113 million) floating solar power plant, the worlda��s biggest, in the nationa��s eastern province ofA�Anhui.

China Three Gorges New Energy started building the 150-megawatt project in July and part of the plant has connected to the grid, according to a 10 December statement. The project features panels fixed to floats on the surface of a lake that formed after a coal mine collapsed, according to the unit. The entire facility is expected to come online by May 2018.

Floating solarA�is getting bigger in China, where ground-mounted projects arena��t used to full capacity because of grid congestion. About 5.6 per cent of solar power generation was idled in the first three quarters, according to data from the National Energy Administration.

Before construction of China Three Gorgesa�� plant, Chinaa��s biggest commissioned floating solar project was a 40-megawatt farm by Sungrow Power Supply in the same province, according toA�Bloomberg New Energy Finance viagra saudi arabia, viagra saudi arabia, viagra saudi arabia, viagra saudi arabia, viagra saudi arabia, viagra saudi arabia, viagra saudi arabia, viagra saudi arabia. .

World’s first floating windfarm to take shape off coast of Scotland

World’s first floating windfarm to take shape off coast of Scotland

Turbines for A?200m Hywind project will be towed from Norway across North Sea and moored to seabed off north-east Scotland

Two of the floating turbines are readied off the coast of Norway for the trip to Scotland.

The worlda��s first floating windfarm has taken to the seas in a sign that a technology once confined to research and development drawing boards is finally ready to unlock expanses of ocean for generating renewable power.

After two turbines were floated this week, five now bob gently in the deep waters of a fjord on the western coast of Norway ready to be tugged across the North Sea to their final destination off north-eastA�Scotland.

The A?200m Hywind projectA�is unusual not just because of the pioneering technology involved, which uses a 78-metre-tall underwater ballast and three mooring lines that will be attached to the seabed to keep the turbines upright. It is also notable because the developer is not a renewable energy firm but Norwaya��s Statoil, which is looking to diversify away from carbon-based fuels.

Irene Rummelhoff, head of the oil firma��s low-carbon division, said the technology opened up an enormous new resource of wind power.

a�?Ita��s almost unlimited. Currently we are saying [floating windfarms will work in] water depths of between 100 and 700 metres, but I think we can go deeper than that. It opens up ocean that was unavailable,a�? she said.

Offshore windfarms are springing up across the North Sea for a reason a�� its waters are uniquely shallow enough to allow turbines to be mounted atop steel poles fixed to the seabed.

However, such fixed-bottom turbines can only be installed at water depths down to 40 metres, making them little use for the steeply shelved coastlines of the US west coast or Japan.

a�?If you look at coastlines around the world, therea��s few that have sufficient area at depths down to 40 metres so if they want to deploy offshore wind, they need to introduce floating wind,a�? said Rummelhoff.

As well as opening up new frontiers such as the Atlantic and the Mediterranean, floating windfarms could be placed farther out to sea to avoid the sort of aesthetic objections thatA�scuppered a A?3.5b windfarm off the Dorset coast.

While Hywind is a minnow among modern offshore wind projects a�� it will power just 20,000 homes compared with the 800,000 byA�one being built off the Yorkshire coastA�a�� proponents say floating turbines could eclipse fixed-bottom ones in the long run.

a�?Looking to the next decades, there might be a point where floating is bigger than fixed based,a�? said Stephan Barth of IEA Wind, an intergovernmental wind power body covering 21 countries.

Bruno Geschier, chief marketing officer at Ideol, a French company hoping to build floating windfarms in Japan, France and elsewhere, said he expected floating farms to begin to take off in the next decade, a�?reaching cruising altitude in the mid-2020s and a big boom in 2030-35a�?.

The commercialisation also means a chance for new countries to emerge as renewable energy leaders. The UK has the most offshore wind capacity in the world, with Germany not far behind, but France, which has none, wants to become a market leader.

a�?Floating wind is an opportunity for France to step on to the podium,a�? saidA�Geschier.

For Statoil, the ambitions go well beyond Peterhead in Scotland, where Hywind will be moored and providing power from October at the latest.

Rummelhoff said floating windfarms will come of age in the areas where conventional ones have been established, as countries such as the UK run out of suitable sites in shallower waters.

But it is also talking with state governments in Hawaii and California about projects, and eyeing Japan and the new, pro-renewables government in Seoul.

Like many new technologies, the biggest challenge will be cost. Behind the turbines at the deepwater port of Stord inA�NorwayA�sits a huge lifting vessel usually used in the oil and gas industry. It is the second biggest of its kind, very expensive to hire a�� and, for now, essential in the process of lifting the turbines off the quayside and floating them.

The first-of-a-kind nature means supply chain complexity, too. a�?We have 15 main contractors. For the future we cannot have 15, we can have between 5 and 10,a�? said Leif Delp, project manager for Hywind.

Statoil said floating wind would be the same cost as conventional offshore windfarms by 2030, while IEA said the cost today was the same as fixed-bottom ones a decade ago.

Experts have said a conventional offshore windfarm with the capacity of Hywind would be less than half the cost. A generous subsidy deal from the Scottish government made the project viable.

a�?Technically, everything is possible. Ita��s just the price tag that comes with it,a�? said Barth.

The cost of Renewables is Plunging faster than Expected

The cost of Renewables is Plunging faster than Expected

The cost of renewables is plunging faster than forecasters anticipated just a few years ago as as technologies like gigantic wind turbines arrive on the market.Thata��s the conclusion of Bloomberg New Energy Finance, whose founder Michael Liebreich estimated that clean energy will reap 86 percent of the $10.2 trillion likely to be invested in power generation by 2040.In a presentation to the research groupa��s conference in London on Tuesday, Liebreich said technology thata��s slashing the costs of wind and solar farms makes it inevitable that clean energy will become more economical than fossil fuels for utilities in many places. The most visible advance is in the scale of wind turbines, highlighted by the chart below.

When it started collecting data in earnest in 2004, BNEF already could see a trend toward bigger machines in the wind industry that deliver more spark to the grid. The scale of those turbines will grow with models planned by Siemens AG and Vestas Wind Systems A/S that already are delivering ones with wing spans bigger than the Airbus A380 double-decker jetliner.

The promise of bigger machines early in the next decade prompted developers of offshore wind farms in Germany to promise electricity without subsidy on their next projects.

a�?One of the reasons those offshore wind costs have come down to be competitive without subsidies is because these turbines are absolute monsters,a�? Liebreich said. a�?Imagine a turbine with a tip height thata��s higher thanA�The Shard.a��a��

The same process of producing more electricity for a lower cost is making photovoltaics cheaper. Liebreich predicted two a�?tipping pointsa�? where the cost of renewables will make power generation fueled by natural gas and coal increasingly unattractive.

a�?The first is when new wind and solar become cheaper than anything else,a�? Liebreich said. The slide below from his presentation indicates that in Japan by 2025 it will be cheaper to build a new PV plant than a coal-fired power generator. That milestone will be passed in India for wind power by 2030.

a�?At that point, anything you have to retire is likely to be replaced by wind and solar,a�? Liebreich said. a�?That tipping point is either here or almost here everywhere in the world.a�?The second tipping point, a little further off, is when ita��s more costly to operate existing coal and gas plants than to take power from wind and solar. The chart below, from BNEF forecasts, indicates that point may arrive in the middle of the next decade in both Germany and China.

Because energy costs vary widely from country to country, ita��s difficult to make firm conclusions about when renewables might be able to overtake fossil fuels on the grid. For example, Brazil relies heavily on hydroelectric dams and France on its nuclear reactors — technologies in much lower use in most other places.

For Liebreich, the economics of wind and solar are becoming compelling enough that ita��s unlikely coal be able to hold onto its dominant position in the global power mix no matter what incentives President Donald Trump implements in the U.S.

a�?This is going to happen,a�? Liebreich said. a�?Coal is declining in the U.S. Nobody is going to make coal great again.a�?

Where will our energy come from in 2030, and how green will it be?

How can the energy industry adapt to meet the needs of a growing population while also supporting low-carbon growth?A�Katherine Hamilton, Director of the Project for Clean Energy and Innovation, and co-chair of the Global Future Council on the Future of Energy, says that this essential transition will not happen without collaboration between large energy companies, entrepreneurs, the finance sector and consumers.

Why should we be thinking about the future of energy?

The energy sector is already changing very rapidly. It is transitioning, we hope, towards greater ability to meet the energy needs of a growing global population with reduced use of carbon, supporting continued economic growth in an environmentally sustainable way.A�This resource will help you to find more additional information.

But that transition will not necessarily happen on its own. We need to get key players in the same room who can bring different experiences and perspectives, and collectively come up with better ideas than any of us could on our own a�� and then work out how to implement those ideas. Hence the need for this Global Future Council.

Who are the key players that need to be involved?

The incumbents are important, of course a�� the large energy companies who own and control the infrastructure, especially in industrialized countries. They are often criticized as part of the problem, but they also have to be part of the solution. In addition, we need the innovators a�� entrepreneurs who are coming up with ideas to disrupt the sector. And we need input from energy consumers, including large corporations and municipalities.

Representatives of the financial sector are important a�� experts in bonds, risk and insurance. There is plenty of capital out there looking for good projects to finance, but the main constraint for investors is the assurance that those projects will find a market. Creating certainty is one important thing politicians and policymakers can do to help a�� and it is they who, ultimately, will need the vision to define goals for the energy sector and devise policies to achieve them.

What are the biggest emerging trends in the energy sector?

The decentralization of energy generation is an enormous trend. Innovation is also being democratized; it is no longer just the incumbents who can innovate. Consumers, increasingly, are in the drivera��s seat; there is more real-time interaction between energy service providers and consumers a�� whether that is the operator of a factory with sophisticated demand response or an Indian farmer using a mobile phone to manage crops.

We are continuing to see drastic reductions in the cost of many renewable technologies as well as greater accessibility to energy storage and efficiency.

How far are we from renewables no longer needing subsidies to compete?

Any time you talk about subsidies for renewables, you also have to remember that incumbent players have benefited from built-in subsidies for decades through policy support and monopoly power. Often there is a misconception that energy was a free market before the idea of subsidizing renewables came along. That is not the case, and we need to recognize that when we ask how best to adjust the market for innovation going forward.

What kind of innovations are we seeing in energy, and what might we expect in the coming years?

The sharing economy will be increasingly important in the transport sector. There is potential to improve efficiency and greatly reduce emissions as we move towards more electric and autonomous vehicles.

There is also room to harness data to make the grid and entire energy ecosystem more efficient. The data is available, through advanced meters and mobile applications, for example, but we have yet to fully exploit that data to move energy to where it is needed, smartly and in real time.

I expect to see more a�?community solara�? projects, as collective consumers invest in generating and storing power. There will be more distributed generation using a variety of technologies, such as solar, wind, geothermal, fuel cells, and hydropower. We will see further innovations in multiple uses of energy storage, such re-purposing car batteries to store electricity.

In the coming years we might see some breakthroughs in carbon capture and storage a�� and, no doubt, there will be innovations and applications nobody has thought of yet.

A�What needs to be on the agenda for energy stakeholders?

Above all, we must have a solid plan to reduce carbon, To reach that, we have to define what we value a�� not just improving access to energy, and guaranteeing energy security to meet the needs of economic growth, but doing all of this in a sustainable way and one in which carbon emissions are drastically reduced. Then we need clear and transparent benchmarks against which to measure our progress.

We also need a vision that combines the decentralized and the centralized a�� embracing more distributed generation, while looking at the larger system and how we can move energy around globally in real time.

Finally, how might the energy sector look by 2030?

I fear that we will be paying for our previous failures to reduce carbon emissions, and being increasingly preoccupied with climate change adaptation. But I also believe that we can have a sector that delivers much higher access to energy than today, with greater use of renewables, incentivizing innovation and creating economic growth while reducing our impact on the planet.
