ABB Alternative energy solutions Technology to meet growing demand for clean energy Stephen R. Burgin Hello, my name Stephen Burgin. I'm here to talk to you about ABB’s alternative energy solutions. World energy consumption is growing xx percent per year, and electricity growth is even higher. Let me tell you a bit about the impact of that growth and what we can technology we offer….

Energy consumption is driving global warming Global warming is one of the most detrimental and undisputed …. Exceptional century. Temperature records in tree rings and elsewhere (purple) reveal that the 20th century (red is instrumental records) was unique in the millennium.

ABB’s has appropiate technologies Adressing global warming, environment and general efficiency of electricity production and delivery Emission free Nature is on our side with windpower Efficiency Microturbines for distributed heat and power We are mainly concentrating on the following alternative energy technology areas: distributed heat and power - here I will talk to you about microturbines, windpower and invisible power... Invisible Underground transmission cables

Nature is on our side The offshore windpower option: Higher power output with the new windformer system Beyond the horizon and out of sight

Windformer - emission free energy Conventional windmills Do more with less: Higher power output per windmill Variable speed generator with HV output Link to the grid by DC connection On- and offshore applications Reduced visual impact Low maintenance Solution with windformer Link to the grid….: - avoids the neeed for syncronization of multiple sources

Efficiency by localizing energy production Microturbines for local CHP 100kW optimal rating High compactness High level integration Low emissions Low maintenance High level integration with ABB products Low emissions thanks to ABB unique lean premix burner Dattwill: commercial operations since early 2001. More than 50 units sold

Invisible power transmission IGBT power electronics, the enabling technology ABB HVAC with reactive compensation Conventional HVAC Key technologies: New converter technology enabled by - Power electronics with low losses at low costs - High computing power of controls New cable technology New filter technology IGBT is the enabler to increase power conversion frequenzy Pulse switch modulation ABB HVDC ABB HVDC-Light

ABB technologies change today’s landscape Vision HVDC Power: 50 MW HVDC Light Traditional HVDC ABB is the first company using IGBT technology Plant size: 10 000 m2 1000 m2 350 m2 Frequency: Technology: 50 Hz Thyristor 1 kHz IGBT 5-10 kHz IGBT++

Next: Fuel cells Cooperation with DuPont: Direct methanol fuel cell No reformer for hydrogen, thus lower costs and simpler logistics First generation available in 2001 Bio methanation, establishing appropiate cooperation

Next: Biogas High rate bio-methanation New fermentation technology High energy yield Dry and wet anaerobic process Use biogas in microturbines to generate Electricity Heat / chilling Bio methanation, establishing appropiate cooperation

From micro-grids to virtual utility A vision 2010: Energy rotation Biomass High-rate Bio- methanation Biogas Gas micro-turbine Agriculture Fertilizer Households Photosynthesis CO2 Energy rotation Decentralized biogas turbines generating electricity and heat feeding into micro-grids for villages and farms Waste can be used as Fertilizer Use of local wind power Connection to transmission grid Centralized control could operate microgrids as virtual utility Optimal solutions for agricultural areas esp. in third world countries
