KiteGen® Stem is a fully automatic, light, cost-effective, technologically advanced high altitude generator that aims at adding a new perspective to the ways humanity produces the energy necessary to sustain itself. The KiteGen® Stem is a new renewable energy technology, which also introduces a new renewable energy field. After having tested a small (40 kW) prototype in 2006, the pre-industrial 3MW prototype is currently under completion and first flight and generation tests are expected in a few months. Usually when we think about renewable energies we think mainly about solar PV technologies, traditional wind farms or hydroelectric plants. From tomorrow we will include energy production technologies based on an, up to now, unexploited resource: the altitude winds. The issues related with energy , the direct link between energy and our life-style, the changes that energy has brought to our lives in the last 100 years and the perspectives for the next 100, the challenges of sustainability etc.. are all fundamental aspects of the same subject. KiteGen® wants to give a sound answer to these challenges by providing a renewable technology that will produce electricity at a cost competitive with the traditional sources based on fossil fuels, thus at a so called “grid parity”. The KiteGen® Stem is in fact an industrial robot that can automatically manage the flight of a large kite. The kite flies at an average height between 1000 and 2000 meters, its trajectory loop is shaped as an "8" and while raising up in height , the kite pulls the two ropes that, at the heart of the machine, activate alternators which produce the electricity (active phase). When the maximum height is reached the automatically controlled kite performs the side-slip manoeuvre (patented) that rewinds the two ropes (passive phase) with a minimum expenditure of energy. Then the cycle restarts. The kite used up to now are derived from the "kite-surf" used by sportsmen, but it will soon become an hyper-technological wing, which will increase its efficiency even more . A KiteGen® STEM is expected to work, on a good site, up to 5800 hours per year at nominal power, so that a farm of 25 KiteGen® Stems can alone provide the energy demands of approx. 70.000 households The ground structure is two orders of magnitude lighter than a same size wind turbine (12 ton. vs. 1500). The structure is shaped as an Igloo of 12 m. diameter and 7 m. high. At the top there is a “Stem”, 21 m. long (a big lamppost) from where lines go up in the sky. The structure is in steel, the stem and the drums that host ropes are in carbon fiber, the ropes are in HM polyethylene and the kite is in composite material. Materials are more or less the same of a wind turbine. KiteGen® Research holds more than 20 patents worldwide registered on various aspect of the technology, it has been awarded several prizes in the field of technological innovation (among others the ENI Awards) and it aims at an imminent industrialization of the technology. The TUV certification of the first 3MW prototype is under way. The KiteGen® Stem can produce clean renewable Energy at a cost competitive with that of traditional fossil sources. It has little or no environmental impact compared to the already limited impact of other renewable sources. It can exploit a huge energy field (estimated in 3600 TW), widely distributed worldwide, for the production of relevant quantity of energy from renewable source and at low cost, moreover with a limited territorial need for its operation. Humanity urgently needs a way of lowering its dependence from fossil fuels: their scarcity and their impact on the environment are limiting our very existence on this planet. Another renewable energy field (the high altitude winds) and a new technology to harness it (KiteGen®) are two fundamental steps towards the goal of a Sustainable Society. .

  • Optimizing the Visual Impact of Onshore Wind Farms Upon the Landscapes – Comparing Recent Planning Approaches in China and Germany
    Ruhr-Universität Bochum Dissertation Submission to the Ruhr-Universität Bochum, Faculty of Geosciences For the degree of Doctor of natural sciences (Dr. rer. nat) Submitted by: Jinjin Guan. MLA Date of the oral examination: 16.07.2020 Examiners Dr. Thomas Held Prof. Dr. Harald Zepp Prof. Dr. Guotai Yan Prof. Dr. Wolfgang Friederich Prof. Dr. Harro Stolpe Keywords Onshore wind farm planning; landscape; landscape visual impact evaluation; energy transition; landscape visual perception; GIS; Germany; China. I Abstract In this thesis, an interdisciplinary Landscape Visual Impact Evaluation (LVIE) model has been established in order to solve the conflicts between onshore wind energy development and landscape protection. It aims to recognize, analyze, and evaluate the visual impact of onshore wind farms upon landscapes and put forward effective mitigation measures in planning procedures. Based on literature research and expert interviews, wind farm planning regimes, legislation, policies, planning procedures, and permission in Germany and China were compared with each other and evaluated concerning their respective advantages and disadvantages. Relevant theories of landscape evaluation have been researched and integrated into the LVIE model, including the landscape connotation, landscape aesthetics, visual perception, landscape functions, and existing evaluation methods. The evaluation principles, criteria, and quantitative indicators are appropriately organized in this model with a hierarchy structure. The potential factors that may influence the visual impact have been collected and categorized into three dimensions: landscape sensitivity, the visual impact of WTs, and viewer exposure. Detailed sub-indicators are also designed under these three topics for delicate evaluation. Required data are collected from official platforms and databases to ensure the reliability and repeatability of the evaluation process.

  • IEA Wind Technology Collaboration Programme
    IEA Wind Technology Collaboration Programme 2017 Annual Report A MESSAGE FROM THE CHAIR Wind energy continued its strong forward momentum during the past term, with many countries setting records in cost reduction, deployment, and grid integration. In 2017, new records were set for hourly, daily, and annual wind–generated electricity, as well as share of energy from wind. For example, Portugal covered 110% of national consumption with wind-generated electricity during three hours while China’s wind energy production increased 26% to 305.7 TWh. In Denmark, wind achieved a 43% share of the energy mix—the largest share of any IEA Wind TCP member countries. From 2010-2017, land-based wind energy auction prices dropped an average of 25%, and levelized cost of energy (LCOE) fell by 21%. In fact, the average, globally-weighted LCOE for land-based wind was 60 USD/ MWh in 2017, second only to hydropower among renewable generation sources. As a result, new countries are adopting wind energy. Offshore wind energy costs have also significantly decreased during the last few years. In Germany and the Netherlands, offshore bids were awarded at a zero premium, while a Contract for Differences auction round in the United Kingdom included two offshore wind farms with record strike prices as low as 76 USD/MWh. On top of the previous achievements, repowering and life extension of wind farms are creating new opportunities in mature markets. However, other challenges still need to be addressed. Wind energy continues to suffer from long permitting procedures, which may hinder deployment in many countries. The rate of wind energy deployment is also uncertain after 2020 due to lack of policies; for example, only eight out of the 28 EU member states have wind power policies in place beyond 2020.

    Airborne Wind Energy Technology Review and Feasibility in Germany Seminar Paper for Sustainable Energy Systems Faculty of Mechanical Engineering Technical University of Munich Supervisors Johne, Philipp Hetterich, Barbara Chair of Energy Systems Authors Drexler, Christoph Hofmann, Alexander Kiss, Balínt Handed in Munich, 05. July 2017 Abstract As a new generation of wind energy systems, AWESs (Airborne Wind Energy Systems) have the potential to grow competitive to their conventional ancestors within the upcoming decade. An overview of the state of the art of AWESs has been presented. For the feasibility ana- lysis of AWESs in Germany, a detailed wind analysis of a three dimensional grid of 80 data points above Germany has been conducted. Long-term NWM (Numerical Weather Model) data over 38 years provided by the NCEP (National Centers for Environmental Prediction) has been analysed to determine the wind probability distributions at elevated altitudes. Besides other data, these distributions and available performance curves have been used to calcu- late the evaluation criteria AEEY (Annual Electrical Energy Yield) and CF (Capacity Factor). Together with the additional criteria LCOE (Levelised Costs of Electricity), MP (Material Per- formance), and REP (Rated Electrical Power) a quantitative cost utility analysis according to Zangemeister has been conducted. This analysis has shown that AWESs look promising and could become an attractive alternative to traditional wind energy systems. 2 Table of Contents 1 Introduction ......................................................................................................

    Statistical characteristics and mapping of near-surface and elevated wind resources in the Middle East Dissertation by Chak Man Andrew Yip In Partial Fulfillment of the Requirements For the Degree of Doctor of Philosophy King Abdullah University of Science and Technology Thuwal, Kingdom of Saudi Arabia November, 2018 2 EXAMINATION COMMITTEE PAGE The dissertation of Chak Man Andrew Yip is approved by the examination committee Committee Chairperson: Georgiy L. Stenchikov Committee Members: Marc G. Genton, Gerard T. Schuster, Kristopher B. Kar- nauskas 3 ©November, 2018 Chak Man Andrew Yip All Rights Reserved 4 ABSTRACT Statistical characteristics and mapping of near-surface and elevated wind resources in the Middle East Chak Man Andrew Yip Wind energy is expected to contribute to alleviating the rise in energy demand in the Middle East that is driven by population growth and industrial development. However, variability and intermittency in the wind resource present significant chal- lenges to grid integration of wind energy systems. The first chapter addresses the issues in current wind resource assessment in the Middle East due to sparse meteorological observations with varying record lengths. The wind field with consistent space-time resolution for over three decades at three hub heights over the whole Arabian Peninsula is constructed using the Modern Era Retrospective-Analysis for Research and Applications (MERRA) dataset. The wind resource is assessed at a higher spatial resolution with metrics of temporal variations in the wind than in prior studies. Previously unrecognized locations of interest with high wind abundance and low variability and intermittency have been identified in this study and confirmed by recent on-site observations.

    FEATURES THE LARGEST RENEWABLE, EASILY EXPLOITABLE, AND ECONOMICALLY SUSTAINABLE ENERGY RESOURCE 1 2 l Giancarlo Abbate and Eugenio Saraceno – DOI: https://doi.org/10.1051/epn/2018101 l 1 Universita` di Napoli “Federico II” – Naples, Italy – [email protected] — 2 KiteGen Venture S.p.a. – Caselle (Turin), Italy Sun, the ultimate energy resource of our planet, transfers energy to the Earth at an average power of 23,000 TW. Earth surface can be regarded as a huge panel transforming solar energy into a more convenient mechanical form, the wind. Since millennia wind is recognized as an exploitable form of energy and it is common knowledge that the higher you go, the stronger the winds flow. To go high is difficult; however Bill Gates cites high wind among possible energy miracles in the near future. Public awareness of this possible miracle is still missing, but today's technology is ready for it. 16 EPN 49/1 sustainable ENERGY RESOURCE FEATURES ropospheric Wind Energy or High Altitude Wind Energy (HAWE), also known as high- wind energy, is a vast and well-known kinetic Tenergy resource. The atmospheric stationary regime is powered by a percentage of the total mean solar radiation (230 W/m2 after reflection to space) around 2%. Gustavson in 1979 [1] estimated the power needed to maintain the stationary regime of the atmosphere as huge as 3,600 TW. Of the 3,600 TW figure, the near-surface wind resources available to wind turbines are in the range 25-70 TW, see figure 1. Near-surface wind and solar technologies also deal with low capacity factors.

For example, Denmark gets 39.1% of its electricity from wind, China has deployed nearly 115 gigawatts of wind energy, the Unit- ed Kingdom increased offshore capacity 22% in 2014 and Germany reached half of its 2020 offshore target of 6.5 gigawatts. Over the past decade, great strides in wind energy technol- ogy development have enabled these impres- sive deployment numbers. R&D collaboration amongst the 21 countries of IEA wind has played a major role in addressing the most dif- ficult to solve wind technology challenges; and collaboration will continue to be important as future challenges are identified and addressed. The IEA Wind Annual Report documents the activities and accomplishments of the IEA Wind mem- ber countries in 2014. The report also shows the wide breadth of research being conducted world-wide, as reflected in the thirteen IEA Wind cooperative research tasks. In 2015, IEA Wind plans to add two new research tasks, to improve wind forecasting and to take a systems approach to wind turbine design.
