Julia Cramer, heading the project at AV, explains: "We have been working together with the renowned RTWH Aachen for a long time and, after the successful cooperation in 2017, are now supporting the solar car project with a variety of materials and technical services as well as being the main sponsor". The primary objective is to test new materials under the extreme climatic conditions of the track.

    Partnership for solar mobility

    Global trends such as climate protection and the conservation of resources coupled with increasing mobility are forcing car manufacturers to rethink. Trends such as electric mobility, networking, autonomous driving and car sharing require totally new vehicle concepts and technologies. Lightweight and functional materials from AV reduce fuel consumption and play an important role in extending the range of electric vehicles, for example. They also impart the required stability.

    Sustainability is a central component of AV's corporate strategy, and solar mobility could make an important contribution to climate protection and the conservation of fossil resources. That is why AV is supporting this ambitious project and intensifying its cooperation with the Sonnenwagen Team. Thanks to its innovative materials, the company is providing solutions for the mobility of the future. One of AV's forward-looking goals is to support automotive concepts in which vehicles generate energy while in motion. Another objective is to test materials that could later be used in other applications. AV is also promoting young talent with this project.

    The new AV Sonnenwagen is scheduled to be presented to the public for the first time in Aachen on 22 July.

    The use and storage of renewable energies is also finding increasing application in private and commercial environments: stationary home battery storage systems based on Li-ion battery technology are a market with a great future. BMZ GmbH, a leading system supplier for lithium-ion batteries, develops such battery home storage devices, which are also marketed under its own name as the EES 7.0, EES 9.0 and ESS X storage series. This means that the regenerative solar power generated in photovoltaic systems can be used in private and commercial applications more independently of the time of day and the position of the sun.

    AV supports the various BMZ battery projects with material selection, during plastic-compatible component design and with CAE-based component simulations to meet the requirements of the UN Transport Test for Batteries (UN 38.3). Further services include moldflow analyses and technical injection molding support.

    "Every battery project is technically demanding, which is why I am all the more pleased that plastics from AV can make an important contribution here," explains Jens Ufermann from AV, who looks after BMZ GmbH locally, adding: "Together with customers like BMZ, we are working on sustainable product and application developments to master the challenges of future battery technologies."

    High requirements for stationary and mobile applications

    Similar to battery systems for mobile applications such as cars, buses, scooters and pedelecs, energy density and safety are important aspects in the development of battery products for stationary use, as is the case with BMZ GmbH's energy storage systems.

    "Our in-depth understanding of the diverse applications of battery systems and our many years of experience in materials for battery applications enable us to provide our customers with both technical expertise and suitable products," says Dr. Julian Marschewski, Market Development Manager in Electric Vehicle Battery Packaging.

    Polycarbonate blends with tailored properties

    Bayblend® (PC+ABS) blends from AV play an important role in both mobile and stationary battery applications, for example in placing individual cylindrical battery cells in 18650 or 21700 format in a cell holder. To achieve this, the material must have excellent mechanical properties, above all high impact strength, but also high flowability in order to achieve the thinnest possible walls between the individual battery cells when manufacturing the cell holders through injection molding.

    Additional safety in later use is provided by the incorporation of flame retardant grades that meet the high flame retardancy standards of Underwriters Laboratories according to category UL 94 V-0.

    Broad range of products

    The AV portfolio for battery applications continues to evolve. For cell holders for holding cylindrical battery cells, pouch cell frames, battery housings and similar applications the focus is on both unfilled (, ) and mineral-filled (, ) along with glass-fiber-reinforced () flame retardant Bayblend® products. AV also offers thermally conductive polycarbonate grades of the Makrolon® TC product family that can contribute to battery thermal management.

    AV, a leading global provider of innovative and sustainable material solutions, shares the students' enthusiasm and will work with them to push existing boundaries to make the project a success. The company has a long-standing partnership with the renowned RWTH Aachen University and, following the successful and fruitful cooperation in the 2017 season, is supporting the solar car project with a variety of materials and technical services as well as being the main sponsor. Both partners have now signed a cooperation agreement on the project.

    Partnership for solar mobility
    "Sustainability is a core component of our corporate strategy, and solar mobility can make an important contribution to climate protection and the conservation of fossil resources," says Dr. Markus Steilemann, CEO of AV. "That is why we are supporting this ambitious project and intensifying our cooperation with the Sonnenwagen team. We use our innovative materials to provide solutions for future mobility. With this project, we are also promoting young talents.”

    Markus Eckstein, first chairman of the Sonnenwagen team, welcomes the extended partnership: "We are very pleased to have AV back as a supporter. The cooperation with AV was already an important mainstay at the recent World Solar Challenge and helped us to reach the finish line in Adelaide as ´Best Newcomer´. The Sonnenwagen team can once again benefit from the high level of material expertise.”

    Innovative materials for future mobility
    The Leverkusen-based company has already gained some experience in solar mobility with innovative material developments: As an official partner of the Solar Impulse project, it made an important contribution to the success of the first manned, round-the-world flight with an airplane powered only by solar energy.

    The test of a polyurethane car repair clearcoat from PPG at the World Challenge 2017, in which the biobased hardener Desmodur® eco N 7300 from AV was used, was also successful. It also withstood the harsh climatic conditions in Australia.

    The material and development cooperation will now be further expanded for 2019. A AV development team will be involved in the production plans of the solar car in order to contribute to an even lighter and more aerodynamic solar car design.

    Successful start at the European Solar Challenge
    As a first step on the way to Australia, the Sonnenwagen team has already successfully mastered the European Solar Challenge on the former Formula 1 race track in Zolder, Belgium. The aim of the race is not only to cover the greatest possible distance within 24 hours, but also to score points with innovations in vehicle development, the most constant 8-lap times and the fastest lap driven. The Sonnenwagen team was able to finish the toughest 24-hour race for solar vehicles in third place in the Challenger class.

    "It couldn't get any better; despite the very difficult race course and the adverse weather conditions, we were able to get the optimum out of the race result," said first team chairman Markus Eckstein after the race. "We are confident that we will be able to take the upturn in success in Belgium with us to Australia and start there with a view to the podium as well.”

    In addition, two members of the association won with an electric car now three years in a row at the e-CROSS Germany, a four-day, climate-neutral rally through North Rhine-Westphalia.

    World's toughest solar race
    The World Solar Challenge is considered to be the toughest solar race on earth and celebrated its 30th anniversary in 2017. Every two years, teams from all over the world compete to be the fastest to cover the 3,000 kilometer stretch from Darwin to Adelaide with homemade vehicles – without a drop of fuel.

    AV supports sustainable urban development /press/covestro-supports-sustainable-urban-development/ /press/covestro-supports-sustainable-urban-development/385751Innovative material solutions for energy-efficient solar houses

    ]]>
    Ongoing urbanization brings with it many challenges, especially in megacities as they are currently developing in countries such as China. Above all, solutions are needed that reduce the energy consumption of buildings and vehicles. The Chinese government is therefore promoting sustainable urban planning concepts and a wider use of renewable energies.

    This is the goal of "Solar Decathlon China", a student competition for building concepts that use only solar energy. The venue for this year's "Olympic games for solar energy and green building industry," as the organizers call the Decathlon, is the city of Dezhou. It is also known as the "Sun City" because it is at the center of the Chinese solar industry. 22 student teams from 37 universities from around the world will take part in the competition.

    With know-how and material solutions, AV supports two student groups in the competition – the joint team of Tongji University Shanghai and TU Darmstadt, and the team Shunya of the Indian Institute of Technology in Mumbai.

    Megacities as a challenge and opportunity

    "The fast-growing megacities in these two countries present particular challenges to population supply, the development of the infrastructure and climate protection," says Dr. Markus Steilemann, CEO of AV. "At the same time, local universities and companies often develop the best solutions for global trends such as progressive urbanization."

    Therefore, close cooperation with local partners is particularly important: "Together with them, we develop innovative and sustainable material solutions for energy-efficient buildings. On that basis we want to help shape future habitats and make the world a brighter place," says Markus Steilemann.

    With such projects, AV is committed to achieving the 17 Sustainable Development Goals (SDGs) of the United Nations. Particular priorities are sustainable cities (SDG number 11) and the use of renewable energy (SDG number 7).

    Solar Decathlon China: holistic residential solutions in demand

    Each team was to design and build a one- or two-story solar house with a floor space of between 120 and 200 square meters. The solution is evaluated according to ten criteria: architecture, market appeal, engineering, communications, innovation, comfort zone, appliances, home life, commuting and energy performance.

    On August 17, the winning concept will be announced. After that the area will be turned into a permanent exhibition for sustainable construction and into the first intelligent low-carbon park in China.

    Sophisticated construction concepts

    The EnergyPLUS Home 4.0 from Tongji University and TU Darmstadt has a modular structure, so that several units can be combined to form an apartment building. AV produces transparent and heat-insulating polycarbonate panels for the façade, as well as polyurethane raw materials for water-based, yet water-permeable outdoor floor coatings. They are a perfect fit for new city drainage systems like so-called sponge grounds that soak in water and direct it into piping systems underground.

    Mumbai's Shunya team's Solarise concept combines regional architectural principles and includes climatic and cultural aspects. It is a net positive energy solar villa with a floor space of 150 square meters, which is suitable for a family of six people comprising all modern amenities for comfortable and sustainable living. Products from AV are used in insulating polycarbonate panels on the roof, in polyisocyanurate insulation panels in walls and floors, and in the coating of the steel framework.

    In focus: renewable energies

    “With the support of the Solar Decathlon China, AV also underlines its commitment to the expansion of renewable energies such as solar and wind power,” says Dr. Christian Haessler, head of Sustainability at AV and former head of its Polymer Research and Development Center in Shanghai. The company was the official sponsor of the Solar Impulse project of the pioneers Bertrand Piccard and André Borschberg, who for the first time circumnavigated the earth with a solar-powered aircraft. In addition, students from the RWTH Aachen University, who participated in a self-built solar car at the World Solar Challenge 2017 in Australia, arguably the toughest solar race in the world, were supported.

    “AV is also involved in expanding wind power, especially in China,” adds Christian Haessler. “Together with partners, we developed a new polyurethane composite for rotor blades of wind turbines. These are more flexible and robust than conventional blades and can be made faster and more economically.”

    Worldwide competition for solar construction

    The first Solar Decathlon events took place from 2002 in the USA. Later offshoots were also established in other regions. The initiator and organizer continues to be the US Department of Energy. This year's Solar Decathlon China will also be hosted by China's Ministry of Energy and other national authorities.
