39 GW of 1,000-MWe ultrasupercritical units in operation out
of a total coal-fired fleet of 734 GW. (See also " China Leads the
Global Race to Cleaner Coal " in our December 2012 issue.)
The rest of the world, like the U.S., lags far behind: At least
three-quarters of the world's operating coal power units use subcritical
technologies, and most are more than 25 years old and
less than 300 MW, the agency noted. Despite the significant fuel
efficiency gains afforded by supercritical and ultrasupercritical
technologies, the technologies' widespread adoption is constrained
by growing water shortages, by a need for flexible generation
to balance renewables, and by costs, the IEA says.
Nevertheless, advanced ultrasupercritical plants aren't too far
into the future, the agency speculates. Though progress is needed
in development and deployment of advanced ultrasupercritical
plants operating at 700C (1,292F) and above, most groups
involved have announced plans to advance a full-scale demonstration
within a decade (between 2020 and 2025). China and
India have already started their own programs, funded by both
the public and private sectors, the IEA notes.
With Fresh Election, Japan Veers Away
from Nuclear Phase-Out
A landslide victory handed by Japanese voters to the Liberal
Democratic Party (LDP) in mid-December saw power in the
country's Lower House shift back to the nationalist-conservative
party that had governed Japan almost continuously since
1955. The LDP had been ousted in a historic defeat only three
years earlier. In his first televised interview since taking office,
newly elected Prime Minister Shinzo Abe (who previously
served as prime minister from September 2006 to September
2007) called for review of plans to phase out nuclear power
in Japan by 2030, endorsing instead the construction of new,
safer nuclear power plants.
The announcement comes just months after an advisory panel
set up by the previous administration led by Prime Minister
Yoshihiko Noda and the Democratic Party of Japan made the
controversial recommendation that Japan should seek to close
all 50 of its viable nuclear reactors by 2030 and increase its
reliance on renewable energy, energy efficiency, and fossil fuels.
The recommendation contained in a document titled " Innovative
Energy and Environment Strategy, " and released by then-Minister
of State for National Policy Motohisa Furukawa, calls for a ban
on new reactors, though it left open the possibility that seven
reactors at varying stages of construction in Japan could be completed.
The former government also urged that exemptions be
granted to its policy so that reactors could be shuttered after
their 40-year lifespans, suggesting the deadline to phase out
nuclear power was flexible.
Japan's Cabinet had then refrained from outright endorsing
the recommendation that had been crafted after nearly a year
of public hearings and deliberation by representatives from
the country's sizeable power sector on what Japan's energy
future should look like. But last December, newly installed
Prime Minister Abe (Figure 3) said one of his administration's
first acts would be to revise the phase-out plan, and he
wasted little time in flanking himself with pro-nuclear ministry
officials. LDP officials, meanwhile, said their election
victory showed a change in public opinion. " Rather than a
nuclear-free nation, what was supported was a move to decide
on the future of nuclear energy after discussing the issue for
periods of between three to 10 years, " Shigeru Ishiba, LDP
secretary-general, was quoted as saying by the Asahi ShimFebruary
