3 The Company Innovative high performance vehicles GreenGT is an independent company that designs, develops and markets clean and sustainable vehicle propulsion systems, with a focus on competition and innovation. At the Service of tomorrow s Vehicles GreenGT s ambition is to offer its know-how to all active players of powered mobility by: providing advice and support for the integration of innovative solutions; supplying high-power electric drivetrains; constructing environmentally clean concept cars and competition vehicles. Bringing Skills Together Our team was formed in April 2008, under the leadership of Jean-François Weber, who had formerly been involved for many years in car racing and the Le Mans 24 Hours event. In particular, in 2005, he developed an electric propulsion system designed for competition cars. With the same enthusiasm, he now leads this great adventure working together with his team mates: Christopher Schwartz, a specialist in fuel cells, and two authentically visionary automobile enthusiasts, Stanislas de Sadeleer and Christophe Ricard. Infrastructures GreenGT has its own infrastructures in Switzerland, in the Lausanne region, as well as in the French Department of Var, adjoining Le Castellet Circuit. These resources enable it to put to the test, very quickly, in a practical context the innovative solutions developed by its engineering research staff. p. 3

5 GreenGT H2 The GreenGT H2 is the first prototype electric/hydrogen competition car. The story began in 2009, when GreenGT first built a prototype electric competition car, the GreenGT 300kW, 100% powered by lithium/ion batteries. As autonomy soon proved to be the feature of the 300kW with most scope for improvement, GreenGT decided to use a 100kW hydrogen fuel cell to provide the additional energy needed for the electric motors. This 100kW fuel cell was then tested and the expected results were confirmed. Based on this work, development of a new chassis and a new more powerful, but far more compact fuel cell (with a linear power of 340kW or 460Hp) was started by GreenGT in In June 2012, the GreenGT H2 project was selected as an innovative project by the French Automobile Club de l Ouest (ACO) and invited to participate in the 2013 Le Mans 24 Hours event. In parallel, a new lightweight twin-engine powertrain, with a power of 400kW or 540Hp, was developed for the H2 prototype. Control electronics and telemetry of the latest generation designed and constructed specifically for the GreenGT H2 ensure the very best on-track performance. The electrical/hydrogen technology used on the GreenGT H2, conceived as a demonstration model, will be applicable to other vehicles needing high power, trucks and other industrial vehicles. p. 5

9 Fuel Cell The fuel cell contains neither batteries nor fuel... It is in fact an electrical generator fed with hydrogen and air that discharges only water. The principle of the fuel cell is a chemical reaction that is the reverse of electrolysis of water. It produces electricity, water and heat through oxidation by bringing together different gases (hydrogen and oxygen). The operating temperature ranges from 60 to 120 C depending on the model. The water is discharged as steam. Possible scope for improvement of fuel cells concerns their weight, complexity and cost. > > > p. 9

10 GreenGT H2 - Innovations GreenGT, whose specificity lies in its role as an integrator, offers an innovative solution through the power density and endurance of its powertrains. Our approach, dictated by the constraints of competition, requires us to deliver efficient and reliable products against short delivery lead times. Innovations developed for the GreenGT H2 prototype: 1. Powertrain with a differential torque function. 2. Powertrain incorporating a twin engine and electric converters. 3. Specific lubrication for an electric gearbox designed for low operating temperatures. 4. Centralized control of electronics and high power currents. 5. Fuel cell: air loop without humidifier. 6.

11 GreenGT H2 - Strong Points «A clean and efficient energy solution» Feasibility The first car to break the 100km/h record in 1899 the «Jamais Contente» was electric! The fuel cell itself was invented in 1839, but it was actually constructed for the first time 120 years later! After playing its part in the conquest of space, the fuel cell will now be incorporated in cars. Today, advances in technology have made these solutions workable. Development The development of the GreenGT H2 prototype and its approval have cost about 5 million Euros. With this investment, GreenGT is pursuing a twofold objective: to point the way to the future of the electric/hydrogen motor and to benefit from experience for the series production of high power powertrains. Car makers and petrochemical, gas and electricity distributors are all currently building new technical and more economic models. So this is an area with high growth potential thanks to the rapid improvements in manufacturing processes and materials, particularly polymers and metals. Energy Independence Ecological consequences, diminishing reserves and energy dependence are all problems associated with fossil fuels. Hydrogen, instead, can be produced simply from water using solar panels, an electrolyzer and a compressor. Hydrogen is therefore a truly independent, economic and ecological energy solution for most countries. p. 11

12 GreenGT H2 - Strong Points «A clean and efficient energy solution» No pollutant: There are no emissions of gas or CO2 or NOx or any other pollutants during the operation of an electric/hydrogen motor. Renewable energy: The hydrogen comes from the electrolysis of water. The water is recomposed when electricity is generated in the fuel cell. This water can then be used again to re-create hydrogen. Clean production of hydrogen: Hydrogen can be produced perfectly using wind or solar energy. «A clean and efficient energy solution» Reliability: Electric motors have 5 times fewer parts than thermal energy engines and are therefore much more reliable. Safety: Hydrogen is less flammable than petrol/gasoline. The tanks on GreenGT s H2 are 3 times stronger than the petrol/gasoline tanks on FIA approved prototypes. p. 12

16 Achievements Swatch / Belenos (2011) Belenos is a company belonging to the Swiss watchmaker Swatch Group. It has been assigned the task of developing future energy supply concepts. Belenos asked GreenGT to assist it in the choice and design of a small electric city car incorporating the hydrogen/oxygen fuel cell developed by the Paul Scherrer Institute. This car, the EVL2, was built in the first half of 2011 and was presented by Belenos in August p. 16

17 Achievements Windreich E (2011) Windreich, a German wind turbine parks operator, asked GreenGT to convert a Jaguar E-Type, for use in promoting its image in Germany.
