Helsinki University of Technology, Otaniemi, Finland
Researcher, Department of Technical Physics (1999 - 2000)
Supervisor: Prof. Peter Lund
Photovoltaics/Green Buildings: Conducted a European Union study on optimal utilisation of photovoltaic-generated electricity in commercial buildings. Identified novel methods for eliminating power conditioning equipment from typical building-integrated PV systems. Developed a model for matching commercial building heating, cooling, and electricity requirements with photovoltaic generation. Clarified the conditions under which buffering of photovoltaic-generated electricity was economically attractive in grid-connected systems.
Fuel Cell Systems: Surveyed applications for small fuel-cell/metal-hydride systems and compared such systems to advanced rechargeable batteries. Investigated opportunities to integrate fuel cells into photovoltaic systems. Expanded the capabilities of a fuel cell/metal-hydride store/electrolyser test bench. Investigated the operation of a PEM fuel cell through hundreds of hours of test bench operation. Modelled the heat and mass transfer at a PEM fuel cell cathode.
Photovoltaics/Green Buildings: Analysed a long time-series of monitored data from a building-integrated PV system. Identified and rectified problems in the monitoring system.
Technical Writing: Assisted in the preparation of the final report for a 5 year, $5,000,000 research project involving multiple foreign partners.
Training: Assisted graduate students in the planning, execution, and writing of their theses.
CETC-Varennes (Natural Resources Canada), Varennes, Québec, Canada
Project Officer (1995 - 1998)
Photovoltaics: Co-edited a book, Photovoltaics in Cold Climates, coordinating the contributions of over a dozen experts from the International Energy Agency. Planned the contents of the book. Reviewed and revised contributions from chapter authors. Authored introductory chapter and co-authored chapter on economics of PV in cold climates.
Batteries/Photovoltaics/Simulation: Developed insulated battery enclosures using phase change materials. Developed simple thermal models and simulation software for these enclosures. Monitored three photovoltaic installations employing these enclosures and demonstrated the accuracy of the model.
Photovoltaics/Monitoring: Performed an in-depth analysis of 500 photovoltaic systems used to power PanCanadian gas well-head equipment in Alberta. Monitored several systems, conducted simulations, and tested components in the laboratory. Identified weaknesses in one component and recommended changes. Showed that the photovoltaic system was over-sized and could be reduced by about 30% in the future.
Icing/Photovoltaics: Surveyed the problem of ice and snow accumulation on photovoltaic arrays. Assessed the efficacy of a proposed snow and ice melting system for photovoltaic modules through monitoring and a model of the module thermal and electrical characteristics.
Batteries: Planned, executed, and analysed thousands of hours of tests on lead-acid batteries for photovoltaic systems, particularly at cold temperatures and low discharge and charge rates.
