Belenos Clean Power Holding Ltd Belenos Clean Power Holding Ltd. Belenos activities in the field of green energy and its storage E. Varkaraki, U. Hannesen, A. Closset 7th International Scientific Conference on Energy and Climate Change – Green Economy 8-10 October 2014, KEPA, UOA, Athens, Greece

Introduction 2007: Belenos Clean Power Holding was founded by N.G. Hayek to develop a sustainable energy chain starting from solar energy Prestigious partners were associated to the project: Swatch Group Ltd, Hayek Engineering, Deutsche Bank, Swiss Federal Institute of Technology Zurich, Paul Scherrer Institut, Ammann-Group, Group E and actor George Clooney Since 2008: Development of a unique FC system running on Hydrogen and pure Oxygen in partnership with the Paul-Scherrer-Institute (PSI) Since 2011: Development of Hydrogen/Air FC system for mobile applications. Redesign of H2/O2 FC system for stationary applications Since 2012: Development of a PEM electrolyser for the production of hydrogen fuel from water and renewable energy

Belenos Fuel Cell System Proprietary design of fuel cell stack and FC system Development of low cost PEM membrane with excellent durability in collaboration with PSI Bipolar plate development with leading supplier for stationary FC systems Integrated system components for improved performance and reduced cost Production capacity for 1MW/month available

Advantages H2/O2 FC over H2/Air FC Higher system efficiency 60 .. 70% with H2/O2 vs. 45 .. 55% with H2/Air Significantly lower cost Power density (W/cm2 active area) is twice as high at same efficiency 80% of FC cost is active area cost (bipolar plates and MEA) Better reliability Very simple system Very few moving parts Fast start-up Full power achievable within a few seconds No startup-time and -energy for air compressor required Independent from ambient air conditions Operation at high altitudes possible Operation at any ambient temperature and humidity possible No degradation due to air pollution

FC system efficiency Belenos H2/O2 FC System efficiency compared to Hydrogenics HyPM HD 16, one of the most efficient systems on the market This performance can be reached due to a very high cell efficiency and extremely low parasitic losses (U/I curve measured with 6 cell stack with 200 cm2 active area at 3.5 barabs and 75 °C)

Hybrid - fuel cell/battery - EV The fuel cell system doubles the range of the vehicle. The fuel cell could also drive the vehicle when the HV battery is empty (with limited power).
