Two years after the G8 leaders' commitment to the broad deployment of carbon capture and storage (CCS) by 2020, significant progress has been made towards commercialisation of CCS technologies. Yet the 2008 Hokkaido G8 recommendation to launch 20 large-scale CCS demonstration projects by 2010 remains a challenge and will require that governments and industry accelerate the pace toward achieving this critical goal. This is one of the main findings of a new report by the International Energy Agency (IEA), the Carbon Sequestration Leadership Forum (CSLF), and the Global CCS Institute, to be presented to G8 leaders at their June Summit in Muskoka, Canada.
Solar electricity could represent up to 20% to 25% of global electricity production by 2050. This important finding emerges from two new analyses by the International Energy Agency (IEA): the solar Photovoltaic (PV) and Concentrating Solar Power (CSP) roadmaps, launched today in Valencia/Spain, during the Mediterranean Solar Plan Conference hosted by the Spanish presidency of the EU. "It is particularly appropriate to present the two solar roadmaps in Valencia today, given that Spain has taken a leading role globally in promoting solar power and other forms of renewable energy," said Mr. Tanaka. "The combination of solar photovoltaics and concentrating solar power offers considerable prospects for enhancing energy security while reducing energy-related CO2 emissions by almost six billion tonnes per year by 2050." The roadmaps detail the technology milestones that would make this possible, highlighting that the two technologies will deploy in different yet complementary ways: PV mostly for on-grid distributed generation in many regions and CSP largely providing dispatchable electricity at utility scale from regions with brightest sun and clearest skies. PV also helps provide energy access off grid in rural areas. Together, PV and CSP could generate 9 000 Terawatt hours of power in 2050.
The cost of electricity in the coming years will depend on a number of key parameters, foremost among them the costs of raising financial capital and the price of carbon. This is one of the main conclusions of Projected Costs of Generating Electricity: 2010 Edition, a new joint study by the International Energy Agency (IEA) and the OECD Nuclear Energy Agency (NEA). The report, which was presented today in Paris by IEA Executive Director Nobuo Tanaka and NEA Director-General Luis Echávarri, comprises the latest data on the costs of electricity generation for a wide variety of fuels and technologies. It stablishes a global benchmark for the costs of power supply. "In a period when many countries are looking to invest in electricity capacity while working to reduce carbon emissions, it provides an indispensable basis for any discussion about electricity generation choices," said Mr. Echávarri. Mr. Tanaka stressed that "to bolster competitiveness of low-carbon technologies such as nuclear, renewables and CCS, we need strong government action to lower the cost of financing and a significant CO2 price signal to be internalised in power markets".
"Significant recent changes in Italy's energy legislation provide the country with new opportunities to build on past successes", said Nobuo Tanaka, Executive Director of the International Energy Agency (IEA) today in Rome at the launch of Energy Policies of IEA Countries - Italy 2009 Review. He highlighted that over the past five years, the Italian government had gone a long way towards addressing some of Italy's considerable energy challenges thus strengthening the country's energy security. "The National Energy Strategy that will be developed as part of the implementation of the new law can provide Italy with a means by which a clear integrated long-term vision for the energy sector can emerge."The IEA publication commends Italy for its continued progress in energy policy. It acknowledges that the country has succeeded in diversifying gas supply routes, at least in terms of pipeline gas, added significant amounts of electricity generating capacity, and is in the process of further diversifying fuels for electricity generation. All of these actions should lead to more secure energy supplies.
The International Energy Agency welcomes the Copenhagen Accord, which provides guidance on the next steps towards a legally-binding agreement on climate change. The Accord provides a clear environmental goal of limiting the increase in global temperature to 2 degrees Celsius. It calls for emissions to peak as early as possible as well as a collective commitment by developed countries to financially support developing country actions in mitigation and adaptation. It also lays out the foundation for support to developing country actions, over and above their unilateral actions. The IEA estimates that developing countries will need to invest around USD 200 billion annually by 2020 to move to a less carbon-intensive energy system. The USD 100 billion pledged by developed countries is a significant contribution towards that goal.
However, IEA calculations show that emission reduction pledges to date fall short of what is needed to limit the long-term concentration of greenhouse gases in the atmosphere to 450 parts per million (ppm) of CO2-equivalent, in line with a 2 degrees Celsius increase. The IEA has produced a blueprint to reach the 450 ppm goal in the energy sector (see World Energy Outloook 2009), and in the first half of 2010 will assess the possible gap between countries' commitments and actions under the Copenhagen Accord and this goal.
