One-quarter global power can come from nuclear by 2050: IEA

One-quarter global power can come from nuclear by 2050: IEA

Write: Saloni [2011-05-20]
Almost one quarter of global electricity could be generated from nuclear power by 2050, the International Energy Agency (IEA) said in a report published Wednesday, bestowing nuclear a major contributor to cut greenhouse gas emissions.

According to IEA forecast, nuclear capacity could be able to grow to 1,200 gigawatts electrical (GWe) by 2050, providing 24 percent of global electricity at that time, if fully supported and well developed.

In Nuclear Energy Technology Roadmap jointly published by IEA and the OECD Nuclear Energy Agency (NEA), the nuclear power target requires nuclear generating capacity growing to more than triple over the next 40 years.

That target was "ambitious but achievable," the roadmap said.

"Nuclear energy is one of the key low-carbon energy technologies that can contribute... to the decarbonisation of electricity supply by 2050," IEA Executive Director Nobuo Tanaka said previously at the East Asia Climate Forum in Seoul.

NEA Director General Luis Echavarri agreed "nuclear has the potential to play a larger role in cutting CO2 emissions."

The roadmap indicated a relatively mature nuclear technology, saying the latest reactor designs, now under construction around the world, "build on over 50 years of technology development."

The expansion of nuclear generators faces no technological challenges but policy-related, industrial, financial and public acceptance barriers, the roadmap underlined, calling supports from governments and better understanding from the public.

Additionally, safe development of civilian nuclear program also requires advanced disposal of high-level radioactive waste and international system of safeguards to prevent proliferation of nuclear fuels and technology.

Nuclear generating capacity worldwide is presently 370 GWe, providing 14 percent of global electricity. The foreseeable expansion of nuclear generation capacity will contribute a 50 percent cut in energy-related CO2 emissions by 2050, according to IEA.
