Vestas Wind Systems A/S has re-established itself as the leading manufacturer for wind turbines with over 10 GW, or 19.6% share, of global installations in 2018, according to GlobalData.

According to Vestas, high level of project commissioning in Americas, Europe, and steady installation activity in Asia-Pacific has aided the company to cross the 10 GW mark for the first time.

In second position was China’s Xinjiang Goldwind Science & Technology Co., Ltd. with over 7 GW of installations, representing around 13.7% share of the annual installations globally. Goldwind maintained its leading position in the domestic market with over 6 GW of installations in China.

Siemens Gamesa Renewable Energy SA (SGRE), which topped the 2017 ranking fell three places and is currently occupying third position. SGRE installed 6.1 GW, with 11.8% share, of the global wind turbine installations for 2018. The fall in the installed capacity, from 9.4 GW in 2017 to 6.1 GW is mainly attributed to a large number of turbines delivered to projects that are still under construction and expected to come online in 2019-20.

GE Renewable Energy remained in the same position, with over 5 GW of turbine installations in 2018. The company stated that the limited growth was due to pricing pressure, shrinking domestic market and an unfavorable business mix.

Envision Energy Limited occupied fifth in the ranking, gaining two places compared to 2017’s ranking with around 3.7 GW of installations, representing 7.2% of the share. Envision Energy continues to remain second in the domestic Chinese market.

Soltec manufactured its first tracker designed for the mounting of bifacial panels in Chile in 2015 and in 2018 opened a bifacial tracking research centre in California. Such commitment is easy to explain: a bifacial solar tracker harvests energy from both its front and rear side, capturing the sunlight reflected on the ground. And under the right conditions, yield will increase by more than 30%.

The standard features of the SF7 solar tracker from Soltec provide bifacial compatibility due to the higher mounting height, a shadow-free backside and wider service aisles between tracker rows. These features mean that the bifacial modules are further off the ground, reducing the intensity of the shading on the tracker itself while enhancing bifacial gain. It also avoids the main disadvantage of most solar trackers: the axis casting shadows on the backside of the bifacial panel.

The double-width aisles between the SF7 tracker rows help increase the capture of the albedo reflected from the ground and from the solar modules of adjacent trackers. Wider aisles also facilitate the passage of array washing and vegetation control vehicles, thereby reducing O&M costs.

The SF7 Bifacial harvests energy from both its front and rear sides, as it captures the sunlight reflected on the ground beneath the solar tracker. Given the right conditions, energy production increases by more than 30%. The solar tracker from Soltec has recently been supplied for a solar project in the Israeli region of Merhavim and Bnei Shimon. The project has a total capacity of 17 MW, of which 2 MW is produced by bifacial modules. The plant is equipped with a total of 534 units of the SF7 Single-Axis Tracker and 64 units of the SF7 Bifacial.

As Emilio Alfonso, commercial vice-president of Soltec for the EMEA region, explains: “the main challenges of this project stem from the extreme weather conditions inherent to a high altitude, desert location. Logistics created challenges when complying with the works schedule, given its location a long way from urban centres and main roads. Fortunately, our experience allows us to successfully work under this type of conditions”.

Pioneers in bifacial tracking

Soltec is a pioneer in bifacial tracking. By 2015 it had already manufactured the first tracker specifically designed to be mounted with bifacial panels for a plant located close to the La Silla European Southern Observatory in Chile. This 1.72 MWp PV plant is for experimental purposes and represents the innovation, research and development invested, making the La Silla solar tracking plant an exceptional project.

Promoted by the Italian developer Enel Green Power, with Soltec responsible for its installation and design, this plant is located on the fringes of the Atacama Desert, in the region of Coquimbo. The site stands at an altitude of 1,800 metres and covers half the energy demand of the European Southern Observatory. Its location is no coincidence for an experimental installation of this type, given that the clean atmosphere of the area facilitates the research work.

The project, which continues to be the only one of its type in the world, incorporates major PV industry innovations. Two different types of trackers have been used for three different types of modules with the aim of analysing both efficiency and productivity. For this, Soltec has specifically designed two different tracker models to maximise the production of the modules used: in the first place, conventional polycrystalline; and secondly, polycrystalline with electronic optimisation which improves efficiency under certain conditions. Lastly, bifacial technology which is the most important type of module at this solar plant.

As a result of this project, Soltec has developed the first solar tracker with bifacial modules specifically designed for industrial plants. This tracker maximises the PV yield of the bifacial module thanks to the fact it makes use of the solar energy reflected on the ground. Bifacial panels have the capacity to harvest this diffuse energy. For conventional modules and optimised modules, Soltec has designed and installed a solar tracker configured with 4 rows of 19 modules in a horizontal layout.

Moreover, the standard design of the solar trackers from Soltec offers one of the highest tolerance levels to gradients on the market: up to 17% in a N-S orientation, thereby minimising earthworks, trench laying and internal roads. The selected configurations create spacious aisles which make O&M work more efficient.

The entire implementation and development of new technologies reflect the research mission of the plant. The project developer, Enel Green Power, decided to use this plant as an experimental field in which to test different technologies under real conditions in order to improve the future of PV production.

CMBlu Energy and Mann+Hummel have signed an agreement for the joint development and industrialization of energy converters for organic redox flow batteries. The aim of both partners is to support electric mobility through the development of the charging infrastructure and offer the energy sector a sustainable and highly cost-efficient storage technology for a successful energy transition.

From the idea to the laboratory, then series production

The business idea for redox flow batteries with organic electrolytes derived from lignin (‘Organic Flow’) was already conceived in 2011 and since 2014, CMBlu has carried out intensive research and development. These batteries essentially consist of two tanks of liquid electrolyte and an energy converter, which consists of a large number of adjacent rows of cells and is therefore also referred to as a battery stack. The liquids are pumped through the battery stacks and is charged or discharged as required.

The technology developed by CMBlu has now reached the prototype stage. The further development and industrialization of the battery stack is regulated in the long-term cooperation agreement with Mann+Hummel. For this purpose Mann+Hummel has created a spin-off named i2M, which is dedicated to the development and commercialization of innovative technologies. In the next step Mann+Hummel will build a complete production line in an European plant. CMBlu will realize special pilot projects with reference customers in the next two years. Starting in 2021, CMBlu plans to market the first commercial systems.

Benefits of organic flow batteries

Similar to the principle of conventional redox flow batteries, CMBlu’s organic flow batteries store electrical energy in aqueous solutions of organic chemical compounds derived from lignin that are pumped through the energy converter, i.e. battery stack. The special feature of the flow batteries is that the capacity and electrical output can be scaled independently. The number of stacks defines the output of the batteries. A higher number of stacks multiplies the output. The capacity of the battery is only limited by the size of the tanks. This allows flexible customization to take into account the respective application area. For example, solar power can be stored for several hours and then fed into the grid at night.

In order to achieve cost-effective mass production, the most important components in the stack were adjusted to the organic electrolyte. In this process, almost the entire value chain for the stacks can be supplied locally. There is no dependency on imports from other countries. In addition, the battery stacks do not require rare-earth metals or heavy metals. The aqueous electrolytes in the system are not combustible or explosive and can be used safely.

Variety of applications in the grid

Organic flow batteries are suitable for numerous application areas in the power grid such as the intermediate storage of power from renewable energy generation or in connection with the balancing of demand peaks in industrial companies. An additional application area is the charging infrastructure required for electric mobility. The batteries enable a buffer storage to relieve power grids which do not have to be upgraded for additional loads. It enables simultaneous fast charging of electric vehicles. Ultimately, a decentralized charging network for electric vehicles will only be possible in connection with a high performance and scalable energy storage system.

Nature as a model for energy storage

The concept is based on the mode of energy in the human body. In the citric acid cycle the body also uses a redox reaction of organic molecules. CMBlu has now succeeded in applying this principle to large-scale storage of electrical energy. For this purpose the company use the mostly unused resource of lignin, which is readily available in unlimited quantities and accrues in amounts of millions of tons annually in the pulp and paper industry. CMBlu’s technology enables a very large and cost effective energy storage system. The battery stack is the core of the system and requires the highest quality and process reliability in the production process.

The manufacture of electrolytes includes a number of filtration steps, which Mann+Hummel performs using new special membranes. This technology further expands its product range and at the same time contributes to build the infractruture needed for electric vehicles.

Ingeteam and BYD have tested and certified at their respective R&D laboratories the compatibility of BYD’s high voltage Battery-Box H 5.1 and 6.4, and Ingeteam’s INGECON® SUN STORAGE 1Play hybrid solar-plus-storage inverter.

The coupling of Ingeteam’s inverter and BYD’s batteries is a complete hybrid system to capture and maximize the use of the solar resource. The versatility of the Ingeteam hybrid inverter in combination with BYD’s HV battery, permits to operate in stand-alone mode, back-up (UPS) mode or self-consumption mode. Thus, on-grid systems can store the solar energy during the day to consume it at night without risk of a power outage in case of a grid blackout, prioritizing the maximum self-consumption ratio at the same time.

During the certification process, BYD implemented a new battery capacity calibration system to improve the measuring and control of the state of charge of the battery. This newest feature was also implemented and certified within the Ingeteam inverter.

BYD’s LiFePO4 high voltage battery, with its 5.1 kWh and 6.4 kWh of capacity -depending on the model-, has been conceived for residential and commercial use, storing the electric energy and optimizing the installation’s energy efficiency thanks to the stabilization of the power supplied.

For its part, the Ingeteam hybrid inverter makes it possible to connect a PV array and a battery bank to the same unit, thereby reducing the cost of the system as a whole. This is a 3 or 6 kW single-phase transformerless inverter, to address residential and commercial installations.

In 7 days Europe’s flagship wind energy event will take place in Bilbao: the WindEurope 2019 Conference & Exhibition. More than 8,000 delegates will gather in the Spanish city from 2-4 April to network, do business, and discuss the theme of this year’s event: ‘Delivering a clean economy for all Europeans.’
There couldn’t be a better time to be in Spain,” WindEurope CEO Giles Dickson says – and the wind industry seems to agree: the exhibition space has completely sold out and several networking events are already at full capacity. With the wind industry already forecasted to be Europe’s leading source of power generation by 2027, all eyes will be on Bilbao next week.

Describing the event, Dickson says “This event is all about people. Firstly, it’s about the people who work in our industry: are there enough of them, are the right skills out there, how can we best support what we hope will be a growing workforce? Secondly, it’s about the broader public: the relationship between citizens of Europe and wind energy. We’ll be looking at how to maintain people’s continued support for the expansion of wind and showing how wind benefits local communities.

With the energy transition ramping up across Europe, coal regions and regions dependent on energy-intensive industries must be central to any renewables strategy. Accordingly, the event will examine how wind can help deliver a ‘just’ energy transition for those regions of Europe.

Why Spain?

This is where the location becomes key. The Spanish wind market is booming – 4 GW of new wind capacity will come on line in Spain this year, creating 13,000 new jobs. But just as importantly, Bilbao and the Basque Country exemplify how the wind industry can support economic transition in heavy industrial areas. Thanks to forward-thinking policy decisions, Dickson says, the Basque Country has transformed its economy and now become a significant industrial cluster for wind energy, producing and exporting cutting-edge equipment and technology: “They really are reaping the benefits of wind: this region now has one of the highest concentrations of the wind energy supply chain anywhere in the world. It goes to show how, even regions without a lot of wind resource can still benefit enormously from the wind industry. Spain, the Basque Country and Bilbao are setting an example that all European countries should follow.

Who will be speaking in Bilbao?

Other countries will be well represented in Bilbao – both commercially and politically. In addition to 300 exhibitors from 50 countries, the conference programme includes the Spanish and Portuguese Energy Ministers and Ministers from Norway and Croatia. Michal Kurtyka, the Polish Minister who chaired the recent UN climate talks in Katowice will be there, joining a host of senior officials from the European Commission and European Investment Bank, as well as National Regulators and Transmission System Operators.
26928115319_5858031d7a_o-(1)
These are just a few of the 155 speakers behind a conference programme set to cover all the key live technology developments, market trends, and the latest on finance and government policy. The programme will also look at grids and system integration, repowering and lifetime extension, recycling of blade waste, PPAs, trade issues and Brexit.

What about networking and side events?

As always there will be a busy programme of side events in parallel to the conference and exhibition. Notably, on 2 April GWEC will be hosting a Women in Wind launch event, while on 4 April there will be a Skills Workshop dedicated to plugging the skills gap in the wind industry. A new addition to the WindEurope event this year, the ‘Thought Leaders Forum’ from MHI Vestas, will let industry leaders, start-ups and policymakers take part in a series of short talks, discussions, interviews and panels in the exhibition hall

Solar PV module manufacturing JinkoSolar reported a sizeable jump in its shipments and margins in 2018. The news was revealed in the company’s 2018 financial results, published March 22. For 2018 on a consolidated basis across its business, JinkoSolar posted a module shipment of 11.4GW in 2018 — a 16 percent increase from the previous year, marking the third consecutive year with ranking top in global delivery and a market share of 12.8%.

Despite a plummeted domestic demand hit by 531 policy, JinkoSolar was still seen successfully developing its business. Its profitability skyrocketed as a result of higher premium model production capacity and higher utility rate of it. JinkoSolar has begun mass production of its flagship Cheetah series last year, which mainly accounts for the increased profitability. Gross margin was 14.0% for the full year 2018, compared with 11.3% for the full year 2017. Income from operations and net income of 2018 achieved an increase of 98.2 % and 186.9% over 2017.

One of the key elements fueling growth for 2018 is a continuation of robust demand for its quality products, the solid partnership with key customers, and optimized production. In spite that the Company has raised their production capacity of high end mono products with mainstream power range of up to 380 W, its supply was still behind the market demand. In 2018, the company has increased the proportion of premium Mono products in its entire business. As for 2019, the advancement of higher efficient Cheetah will still be a focus of JinkoSolar, and is expected to further drive the sales and revenue. On the other hand, driven by new industry norm of grid parity, JinkoSolar has been a pioneer taking active part in development of the dual side module with transparent backsheet such as Swan, which will bring more changes in its product portfolio.

Looking ahead to 2019,given that the demand remains high, the visibility of order is very positive according to JinkoSolar.

Two technologies that were immature and expensive only a few years ago but are now at the center of the unfolding low-carbon energy transition have seen spectacular gains in cost-competitiveness in the last year. The latest analysis by research company BloombergNEF (BNEF) shows that the benchmark LCOE for lithium-ion batteries has fallen 35% to $187 per megawatt-hour since the first half of 2018. Meanwhile, the benchmark LCOE for offshore wind has tumbled by 24%.

Onshore wind and photovoltaic solar have also gotten cheaper, their respective benchmark LCOE reaching $50 and $57 per megawatt-hour for projects starting construction in early 2019, down 10% and 18% on the equivalent figures of a year ago.

BNEF’s analysis shows that the LCOE per megawatt-hour for onshore wind, solar PV and offshore wind have fallen by 49%, 84% and 56% respectively since 2010. That for lithium-ion battery storage has dropped by 76% since 2012, based on recent project costs and historical battery pack prices. Looking back over this decade, there have been staggering improvements in the cost-competitiveness of these low-carbon options, thanks to technology innovation, economies of scale, stiff price competition and manufacturing experience.

The most striking finding in this LCOE Update, for the first-half of 2019, is on the cost improvements in lithium-ion batteries. These are opening up new opportunities for them to balance a renewables-heavy generation mix. Batteries co-located with solar or wind projects are starting to compete, in many markets and without subsidy, with coal- and gas-fired generation for the provision of ‘dispatchable power’ that can be delivered whenever the grid needs it (as opposed to only when the wind is blowing, or the sun is shining).

Electricity demand is subject to pronounced peaks and lows inter-day. Meeting the peaks has previously been the preserve of technologies such as open-cycle gas turbines and gas reciprocating engines, but these are now facing competition from batteries with anything from one to four hours of energy storage, according to the report.

Offshore wind has often been seen as a relatively expensive generation option compared to onshore wind or solar PV. However, auction programs for new capacity, combined with much larger turbines, have produced sharp reductions in capital costs, taking BNEF’s global benchmark for this technology below $100 per MWh, compared to more than $220 just five years ago.

Although the LCOE of solar PV has fallen 18% in the last year, the great majority of that decline happened in the third quarter of 2018, when a shift in Chinese policy caused there to be a huge global supply glut of modules, rather than over the most recent months.

Continuing its commitment to invest in its mature gas turbine fleets to keep them competitive in today’s dynamic energy marketplace, GE has announced the launch order for its new GT26 HE (high efficiency) gas turbine upgrade with Uniper for the utility’s Enfield Power Station in greater London.

The GT26 HE upgrade also marks other GE firsts:

• First upgrade that takes the best technologies and capabilities from GE’s industry-leading F and H class fleets to create a robust solution for GT26 power plant operators.
• First upgrade that blends both GE and Alstom’s technology and expertise across all major components of a gas turbine solution.

Key performance benefits include:

• Higher efficiency for combined-cycle power plants:
– 2+ percent base load increased efficiency, translating to as much as $4 million in fuel savings annually per unit.
– Up to 1 percent increased efficiency in part load, yielding up to $1 million in fuel savings a year per unit.
• Increased plant output from 15 megawatts (MW) up to 55 MWs per unit, improving revenue opportunities.
• Extended inspection intervals up to 32,000 hours, reducing long-term maintenance costs.

Helping revitalize Uniper’s Enfield power station

Uniper’s Enfield power plant in London will be the first site to install the new GT26 HE technology in 2020 with several significant benefits that GE expects to exceed. These benefits will include increased megawatt output, improved plant and gas turbine efficiency, and extended maintenance intervals and operating hours to enable Enfield to consistently elevate its position on the dispatch curve in the highly competitive U.K. power market and ramp up its annual operating hours.

H-Class technology infusion drives high-efficiency performance

The GT26 HE upgrade provides a leap forward in efficiency, output and maintenance interval extensions. It’s powered partly through advanced technology from GE’s flagship HA gas turbine, the largest and most efficient in the industry, with additive manufactured parts and innovations in aerodynamics, material science and combustion dynamics. It embeds technology breakthroughs across every major component of the GT26 frame—turbine, compressor and combustor—to take turbine performance to a new level, significantly decreasing fuel costs while increasing full-load output and extending maintenance intervals.

The new upgrade also features the best of GE’s research and development centers in both the United States and Switzerland, including unique engineering elements:

• A low-pressure turbine used in GE’s H-class technology.
• High-pressure turbine improvements to increase efficiency, utilizing GE’s F-class technology.
• Advanced combustor engineering incorporating additive manufactured parts to deliver high performance, reduce cooling requirements by approximately 15 percent and lower relative emissions.
• A new 3D aero-profile compressor configuration to provide best-in-class base-load and part-load performance.
