Unfortunately, sometimes wind turbines cannot be used even though it is a windy day. The energy that is generated is more than the power grid can absorb and gets lost. This problem is now being solved at Nuon’s Prinses Alexia Windpark in Zeewolde, the Netherlands. Dutch company Alfen has developed a mega energy storage system by connecting a large number of BMW car batteries. The system stores the surplus of energy so that it can be used when the grid requires the power at a later moment in time.

Together with BMW and Nuon, Alfen launched its 3 MW storage system at the Prinses Alexia Windpark in Zeewolde on Wednesday 28 June. The system will be expanded to 12 MW over the coming period, making it the largest storage project in the Netherlands.

 

This is the second project that connects energy storage to a wind farm. In May this year, Alfen realized a 1 MW storage system linked to wind farm Giessenwind at Giessenburg.

With the project at Prinses Alexia Windpark, Nuon and its parent Vattenfall make an important step forward in realizing their sustainable ambition to be climate neutral in 2050. This will enable Nuon to make flexible use of renewable energy without wasting energy.

Nuon is looking further: for example, they are planning to install a battery in residential areas with many houses with rooftop solar. In this way residents can use their solar energy that is generated during the day to charge their car at night.

In collaboration with the Chinese EPC partner Liyu, MAN Diesel & Turbo has won two further orders for CHP energy production in China. Based on MGT series gas turbines, the compact plants will be delivered to subsidiaries of the Chinese energy firm ENN Group.

One of the CHP plants, optimized for natural gas operation, will be used in an industrial zone in Dongguan City (Guangdong Province) and in addition to about 6 MW of electricity it will also provide 13 MW of heat. With the same performance data, the second CHP plant will supply a paper mill in Huaian (Jiangsu Province). Surplus heat from the gas turbine alternator packs will be utilized with high efficiency and will benefit the local production processes in the form of process steam.

 

MAN Diesel & Turbo now has a number of projects in the People’s Republic in which its CHP technology has replaced the former energy production based on coal. Through the changeover to natural gas fuel and efficient utilization of surplus heat, these projects are supporting the targets set by the Chinese government for increasing efficiency and reducing emissions. The success of MAN MGT gas turbines is reflected by numerous orders placed by end customers in China as well as Germany.

Hamburg, 26 June 2017. Erdem Holding A.S. has placed another order with Nordex to deliver and install a wind farm. The manufacturer is to supply ten N131/3900 turbines for the “Eber” wind farm. A Premium Service covering at least 15 years also forms part of the deal.

The “Eber” site is located 250 kilometres to the south-west of Ankara, near to the city of Afyonkarahisar in western Anatolia. At this altitude the average annual wind speed is 7.8 m/s. The N131/3900 is especially designed for sites with medium to low average wind speeds. Nordex will be supplying the turbines on 84 metre tubular steel towers. Installation is scheduled for spring 2018. Then from the end of 2018 the 39 MW wind farm is to produce 136,000 MWh of clean electricity.

 

“Eber“ is now the fourth wind farm to be ordered from Nordex by Erdem Holding A.S.. Erdem Group operates in the area of telecommunications, energy, construction, construction and building materials, real estate, recycling and waste management sectors and now has been diversifying into the field of renewables. The “Eber” project is the first one for which Nordex will be producing and supplying its N131/3900 turbines.

The Qinghai Province, located in Northwest China, has successfully run on 100 per cent renewable energy for seven continuous days, as part of a trial conducted by the State Grid Corporation of China. The trial – which ran from 17 June to 23 June – saw the entire province generate all of its power needs with clean energy sources, including solar, wind and hydro power. The trial in the Qinghai Province – which has a population of around 6 million people – was designed to prove that fossil fuels will not be required in the future.

Quan Shenming, General Manager of Qinghai Electric Power Corporation, a subsidiary of State Grid Corporation, said: “Being the first trial of this kind in the country and a major step in the transformation of energy supply, it will be of great importance in promoting the use of clean energy in China in a sustainable and effective way.”

 

During the seven day period electricity use was 1.100 GWh, the equivalent of 535,000 tonnes of coal. Hydro contributed as much as 72.3 per cent of the electricity, with new energy sources including wind and solar providing the balance.

Qinghai has ample resources for solar and hydro power generation. As of May 2017, Qinghai’s power grid had a total installed capacity of 23.4 GW, around 82.8 per cent of which came from solar, wind and hydro power.

According to the provincial 13th Five-Year Plan, the Qinghai Province plans to expand its solar and wind capacity to 35 GW by 2020 and supply 110.000 GWh of clean electricity every year to central and eastern parts of China, Xinhua News said.

China plans to invest 2.5 trillion yuan ($366 billion) in renewable energy technologies by 2020, creating more than 13 million jobs, according to the National Energy Administration (NEA). In the first quarter of 2017, China installed an impressive 7.21 GW of new solar capacity. Total installed solar capacity now stands at around 85 GW – according to the NEA.

The 2017 edition of the BP Statistical Review of World Energy, published in June 13, shows global energy markets continuing to undergo long-term changes as they also adapt to nearer-term price challenges. Data published in the Review – the 66th annual edition – clearly demonstrate the long-term transitions now underway in the markets, with a shift to slower growth in global energy demand, demand moving strongly towards the fast-growing developing economies of Asia, and a marked shift towards lower carbon fuels as renewable energy continues to grow strongly and coal use falls.

At the same time, energy markets are adjusting effectively to nearer-term challenges, with the oil market in particular adjusting in 2016 to the oversupply that has dominated the market in recent years.

 

In 2016, global energy demand was weak for the third consecutive year, growing by just 1%, around half the average growth rate of the past decade. Once again, almost all this growth came from fast-growing developing economies, with China and India together accounting for half of all growth.

The year’s low prices drove demand for oil higher by 1.6% while growth in production was limited to only 0.5%. As a result, the oil market returned broadly back into balance by mid-year, but prices continued to be depressed by the large overhang of built-up inventories. Natural gas production was also adversely affected by low prices, growing by only 0.3%. US gas output fell in 2016, the first reduction since the advent of the shale revolution in the mid-2000s.

Renewables were again the fastest-growing of all energy sources, rising by 12%. Although providing still only 4% of total primary energy, the growth in renewables represented almost a third of the total growth in energy demand in 2016. In contrast, use of coal – the most carbon-intensive of the fossil fuels – fell steeply for a second year, down by 1.7%, due primarily to falling demand from both the US and China.

The combination of weak energy demand growth and the shifting fuel mix meant that global carbon emissions are estimated to have grown by only 0.1% – making 2016 the third consecutive year of flat or falling emissions. This marks the lowest three-year average for emissions growth since 1981-83.

Review highlights

Primary energy

• Global energy demand grew by 1% in 2016 – similar to rises of 0.9% and 1% seen in 2015 and 2014 respectively and significantly lower than the 10-year average rate of growth of 1.8%.
• Almost all growth came from fast-growing developing economies; China and India together accounted for around half of all growth.
• Indian energy demand grew by 5.4%, a similar rate to that seen in recent years.
• Chinese energy demand, however, grew by 1.3%. This is close to the 1.2% rise in energy demand in 2015 and around a quarter of its 10-year average growth. Average growth during 2015 and 2016 was the lowest over a two-year period since 1997-98. Despite this slowing, the incremental increase in demand in China made it the world’s largest energy growth market for the 16th consecutive year.
• Demand from the developed OECD countries remained essentially flat (rising just 0.2%).

Oil

• Dated Brent averaged $44 a barrel in 2016, down from $52 in 2015 and the lowest annual average price since 2004.
• Global oil consumption grew strongly, rising by 1.6%, or 1.6 million barrels a day (mmb/d), above the 10-year average rate for a second consecutive year. Strong increases in demand were seen from India (up 0.3mmb/d) and Europe (up 0.3mmb/d) and while demand from China continued to grow (up 0.4mmb/d) it was lower than in recent years.
• Weak prices impacted the growth of global oil production which rose by just 0.5% – the lowest increase since 2009 – or 0.4mmb/d.
• Within this total, production from OPEC increased by 1.2mmb/d, with significant increases seen from Iran (up 0.7mmb/d), Iraq (up 0.4mmb/d) and Saudi Arabia (up 0.4mmb/d).
• In contrast, non-OPEC oil production fell by 0.8mmb/d, the biggest annual decline for around 25 years. The largest output falls were from the US (down 0.4mmb/d), China and Nigeria (each down 0.3mmbd).

Natural gas

• Global natural gas consumption rose by 1.5% in 2016, slower than the 10-year average rate of 2.3%. However, there were strong increases in gas consumption in Europe (up 6%), the Middle East (up 3.5%) and China (up 7.7%).
• Global natural gas production rose by only 0.3% – the weakest growth in gas output for 34 years, outside the financial crisis. With lower gas prices, US gas production fell for the first time since the shale gas revolution began. Australian gas production rose significantly as new LNG facilities came on stream.
• Global LNG imports/exports grew by 6.2%, driven by the new Australian output. LNG production is expected to grow by around 30% in next three years as further new projects come on line.
• The rise of LNG trade reflects an ongoing continuing fundamental shift in global gas markets towards greater integration, but also towards more competitive and flexible markets – with increasing volumes of LNG under shorter or smaller contracts or uncontracted.

Coal

• Global coal consumption fell for the second successive year, down by 1.7% or 53 million tonnes of oil equivalent (Mtoe). This decline brought coal’s share of primary energy production to 28.1%, its lowest share since 2004.
• Declining consumption was driven primarily by the US (down 8.8%, 33Mtoe), and China (down 1.6%, 26Mtoe).
• World coal production fell by 6.2% or 231Mtoe, the largest annual decline on record. The falls in production were again driven by China (down 7.9% or 140Mtoe) and the US (down 19%, or 85Mtoe).
• In the UK, coal consumption more than halved (-52.5%). UK coal consumption has now fallen to levels last seen at the start of the Industrial Revolution around 200 years ago. The UK power sector recorded its first ‘coal-free’ day in April 2017.

Renewables

• Once again, renewables were the fastest growing energy source in 2016. Not including hydroelectric power, renewable energy grew by 12%. While below the 10-year average rate of growth for renewables of 15.7%, this still represented the largest annual incremental increase in output on record (an increase of 55Mtoe – more than the decline in coal consumption).
• Renewables now provide a share of just under 4% of primary energy.
• More than half of growth in renewable power came from wind, which rose by 16% in the year. Solar energy grew by 30%. Despite solar energy making up only 18% of renewables output, growth in solar represented around a third of the overall growth in renewable power.
• In 2016, China became the world’s largest single producer of renewable power, overtaking the US, and Asia Pacific overtook Europe & Eurasia to become the largest producing region for renewable power.

Other fuels

• Nuclear power generation grew by 1.3%, or 9.3Mtoe, in 2016. A 24.5% annual increase in Chinese nuclear output accounted for all the net growth in nuclear power. China’s incremental increase of 9.6Mtoe was the largest from any country since 2004.
• Hydroelectric power generation increased by 2.8% in 2016 – rising by 27.1Mtoe. The largest incremental growth again came from China and then the US.

IRENA, launched past May the 15th in a webinar from Abu Dhabi the new release of the Global Atlas 3.0 for Renewable Energies. It has been developed in partnership with the Computing and Software Development Service from CENER, and it is focused on the improvement of the usability from the user side, including new features and functionalities for mapping resources from different renewable energies.

The new Global Atlas 3.0 from IRENA, is an on-line geospatial platform which allows to perform a quick assessment of the renewable resources and the potential for energy generation in anywhere around the world. That’s why this tool is specially useful for miss-prospected markets, where there is a lack of real measurements for solar and wind energies and often, where numerical series are hard to get. And all of them are really critical when planing projects for the development of energies.

 

The Global Atlas 3.0, has been developed thinking about how different user groups may search the available maps and tools and manage the results (galleries). A most important added feature is the possibility to populate and share them (private and social network sharing option). The permanent underlying idea has been to provide a useful and appealing interface for dynamic project development.
In the near future a comprehensive view of all renewable energies may open the scope for new technologies and business models such as hybridizations, microgrids, virtual power plants, energy storage services, all of them positively contributing to balanced energy systems.

During the webinar, transmitted in streaming, some available new features and functionalities where explained, like how user can find information in map format about different energy resources (wind, solar, geothermal, biomass), how comments can be added or how to locally work with them. In addition, some tests about some of the available tools from the platform for the assessment of the energy capacities where performed. Tools for biomass-energy production simulation, for PV batteries or for grid integration of a PV system.

The webinar presentation attended by IRENA and CENER technicians is available in IRENA’s Youtube Channel.

From the deep fjord outside Stord on the west coast of Norway, the floating wind turbines will be towed to Scottish waters. The world´s largest floating wind project will be located 25 km off the coast of Peterhead in Aberdeenshire, Scotland, at water depths between 90 and 120 m.

The floating foundations in the Hywind project are ballast-stabilized and anchored to the seabed with mooring lines. With their lightweight nacelles, Siemens Gamesa large direct drive wind turbines are particularly suited for floating foundations.

 

The Hywind concept has already proven its effectiveness in 2009, when Statoil and Siemens Wind Power successfully installed a 2.3 MW Siemens Wind Power turbine at the first full-scale floating wind turbine project worldwide, Hywind Demo.

At the same time, Siemens Gamesa gathered a lot of experience on the specific requirements regarding the control parameters on a moving wind turbine under offshore conditions. For the floating installation, the technicians developed new controller algorithms for rotor pitch and yaw drive regulation.

The most important key success factor for the future of floating wind turbines is concepts which are cost (LCoE) competitive with bottom fixed foundations.
In the Scottish pilot project Siemens Gamesa and Statoil have been working close to develop a concept for commercial and large scale offshore wind parks which is cost efficient and with low risk.

Commissioning of the Hywind project is planned for 4Q17.

The majority of operating floating wind farms are currently located in Europe. However, California, Hawaii, Japan and Taiwan are attractive geographies for floating wind power turbines in the future.

Last week, Vestas released the latest iteration of their wind turbine product portfolio, with a new 4 MW product platform accompanied by a 150 m rotor diameter. As the wind energy market continues to mature and become more competitive, original equipment manufacturers (OEMs) are forced to continually innovate new wind turbine products to remain differentiated to their competition.

Technical innovation in the wind energy market continues to advance at a rapid pace. Competition in global markets is fierce, and OEMs are pushed to continually innovate new wind turbine products to differentiate. MAKE Consulting has published a research note on this topic, entitled Next Generation Wind Turbine Models, including 35 pages of analysis and over 50 charts detailing expected new product and technology developments for seven leading turbine OEMs and Aaron BarrSenior Technology Advisor at MAKE Consulting, reviews this new trend.

 

Wind turbine life cycles are expected to shorten, as new products will displace wind turbines released only a few years ago. Furthermore, as new larger rotors are introduced in the onshore market, many existing products will be migrated in wind class suitability. This product migration to higher wind classes will further reinforce the competitive cycle for new product innovation.

The penetration of 3 MW platforms has increased steadily, and now represents over 23% of global installs, up from 8% just 5 years ago.3 MW turbines were installed in more than 38 global onshore markets in 2016, indicating that even emerging markets are quickly transitioning to the latest generation of larger wind turbines. The 3 MW product platforms benefit from economies of scale relative to Balance of Plant (BOP), Operations and Maintenance (O&M) and logistics costs. As these platforms secure more volume, the economies of scale are also extending to the supply chain and resulting in more competitive turbine costs.

The trend to larger turbines will manifest in the next generation of 4 MW platforms for the onshore market. The rotor diameters of these next generation onshore products will exceed 150 m. Significant logistics challenges loom for blades longer than 70 m. Many OEMs will respond by innovating modular blades and advanced logistics solutions to circumvent shipping limitations.

In the offshore market, leading OEMs are expected to accelerate wind turbine growth even faster than the onshore segment. The next generation of 10-12MW wind turbines are expected within the next years, as R&D is in full swing within the leading offshore wind turbine manufacturers. The massive 12 MW wind turbines with rotors in excess of 200 m are being planned for the offshore market, as wind turbine size remains the single most important factor to differentiate in the offshore segment.

MAKE anticipates that this trend will continue, and we will see many more new product announcements over the coming months and years.

The global wind operation and maintenance (O&M) market is set to grow from just over $13.7 billion in 2016 to around $27.4 billion by 2025, representing a compound annual growth rate of 8.0%, according to research and consulting firm GlobalData.

The company’s latest report states that the O&M of a wind farm is essential as it contributes to value creation, increases turbine availability, and improves returns. Aging wind turbines and the failure of components such as blades and gearboxes are the major driver of the burgeoning market.

 

Anchal Agarwal, Power Analyst for GlobalData, explains: “Offshore wind accounted for just over 8% of the total wind O&M market in 2016, and is expected to contribute 18.4% by 2025. This is because the technology is increasingly being explored across the world, for its high yield, due to stronger and more consistent winds in comparison to onshore; and has the scope to construct massive Gigawatt-scale projects.

Indeed, offshore wind attracts higher O&M costs than onshore wind due to higher turbine maintenance, higher logistics costs, and a lack of skilled manpower.

China is the largest wind O&M market in the world and accounted for 30% of the global market size in 2016. GlobalData expects that the country will maintain its leading position, with a share of 27.4% in 2025. Increasing installations of wind power will provide opportunities for O&M in the forecast period. A large installation base, government plans, and strict environmental laws are the major drivers for the growth of the country’s wind power market.

The US is the second-largest wind O&M market, with a share of 14.6% in 2016, and is also expected to maintain its position in 2025. Germany – the largest European wind O&M market – accounted for 14.3% of the global market in 2016, and is expected to hold an 11.9% share in 2025. The major reason for key countries losing their market share is the emergence of newer markets, such as India and the UK. India’s share of the global wind O&M market is expected to increase from 5.6% in 2016 to 6.4% in 2025, while the UK’s share will increase from 5.3% to 7.1% over the same period.
