 Covering the main low‐carbon energy technologies

 Based on a scenario to halve energy‐related CO2 emissions by 2050 (near decarbonisation of electricity)  Assess current status of technology and set out specific technology targets to be achieved and by when  Other barriers that need to be overcome (e.g. legal, regulatory, financial, public acceptance, etc.)  Policy support required for R&D and for deployment  Identification of roles & responsibilities, i.e. who needs to do what and when  Looks to 2050, but focus on near‐term actions and milestones (next 10 years) 21 ETP 2010 BLUE Map: Nuclear

 Assumes 1 200 GWe of nuclear power by 2050 (up from 370 GWe today); 610 GWe in ETP Baseline  9 600 TWh/year of electricity, 24% of global total  Need to add 25 GWe/year in 2020s, rising to 40 GWe/year in 2040s  Allowing for life extension and larger units, could require 20‐25 new units per year  High Nuclear case has 2 000 GWe nuclear by 2050, nearly 16 000 TWh, 38% of global electricity  Model shows this would be cost‐effective (against CCS), but IEA doubts feasibility 22 Electricity Production by Source in Baseline & BLUE Map Scenarios

29 Key Findings (1)

 Nuclear is a mature low‐carbon energy technology that is already available for wider deployment  In the ETP BLUE Map scenario, nuclear capacity grows to 1 200 GWe by 2050, providing 24% of global electricity  Obstacles to this expansion are mainly policy‐related, industrial and financial, rather than technological  But in the longer term, technological development will be needed for nuclear to remain competitive  A clear and stable commitment to nuclear as part of national energy strategy is a prerequisite  Financing will be a major challenge, and government support may be needed for private‐sector investment 30 Key Findings (2)

 Industrial capacity to build nuclear plants will need to double by 2020 for expansion in line with the scenario; fuel cycle capacities will also need to increase  A great increase in highly qualified and skilled human resources will also be needed  Progress needs to be made in building and operating facilities for the disposal of spent fuel & high‐level waste  Safeguards and physical protection measures must be maintained and strengthened where necessary  Generation IV reactor and fuel cycle technologies may offer improved sustainability, economics, proliferation‐ resistance, safety and reliability, starting before 2050 31 Key Actions for Next 10 Years

 Demonstrate the ability to build the latest nuclear plant designs on time and within budget  Develop the industrial capacities and skilled human resources to support sustained growth in nuclear capacity  Establish the required legal frameworks and institutions in countries where these do not yet exist  Encourage the participation of private sector investors in nuclear power projects  Make progress in implementing plans for permanent disposal of high‐level radioactive wastes  Enhance public dialogue to inform stakeholders about the role of nuclear in energy strategy  Expand the supply of nuclear fuel in line with increased nuclear generating capacity 32 The Nuclear Energy Roadmap was released on 16 June 2010
