how to build low carbon technology
Tehnopedia.net- With fossil fuels expected to supply over 70% of the world's
energy needs by 2040, we face some urgent questions: where should efforts be
focused in reducing greenhouse gas emissions? Which technologies hold the most
promise? There are a range of low-carbon solutions and given the challenge, we
will need them all. We hear a lot about the advances being made by renewable
sources of energy such as solar, wind and hydro-electricity and these are
certainly valuable technologies in combating climate change. But how can we
really make a major impact in reducing carbon emissions from large power plants
and industrial facilities? Enter carbon capture and storage - or CCS - a
technology that captures carbon dioxide from fossil fuel production and
permanently stores it underground.
In November 2014 the Global CCS Institute released its
flagship publication – the annual Global Status of CCS report. This
comprehensive annual update is the pre-eminent source of information on the
development of CCS around the world. A lot of work went into updating
information in the report, in collaboration with the CCS industry, as there had
been quite significant changes to the CCS landscape in the preceding 12 months.
This included the launch of a large-scale CCS project in the power sector and
the beginning of construction of the world’s first large-scale CCS project in
the iron and steel sector.
The world’s first large-scale CCS project in the power
sector
Large-scale CCS is now a reality in the power sector with
the October 2014 launch of the Boundary Dam Integrated Carbon Capture and
Sequestration Demonstration Project in Saskatchewan, Canada. Boundary Dam is
the first commercial CCS plant in the power sector, removing 90 per cent of the
CO2 produced by electricity generation from lignite coal at Production Unit
No.3 of the SaskPower facility.
captured CO2 is primarily used for enhanced oil recovery (EOR) at the nearby Weyburn oil field, although amounts are also to be stored in deep geological formations at the Aquistore site. The success of the Boundary Dam project and the progression of additional projects through planning and construction, indicates that CCS technologies for application in the power sector are 'market ready'.

A family of technologies for a range of industrial
applications
The next 18-24 months will see CCS deployed across a range
of industries and storage types. A further two large-scale CCS power projects
are in construction in the US - the Kemper County Energy Facility in
Mississippi and the Petra Nova Carbon Capture Project in Texas. Both projects are
expected to be operational in 2016. Also in the US, the Illinois Industrial CCS
project slated for launch later this year will capture CO2 from the Archer
Daniels Midland corn-to-ethanol plant in Decatur, Illinois for storage in an
onshore deep saline formation. The Abu Dhabi CCS project in the United Arab
Emirates is under construction and from 2016 will provide the world’s first
large-scale demonstration of CO2 capture from iron and steel production.
In addition to the 22 large-scale CCS projects currently in
operation or construction around the world, 14 projects are in advanced stages
of planning, many of which are likely to be in a position to make a final
investment decision over the coming year. Together this group of projects
covers a range of applications for CCS and could extend to around ten the
number of large-scale CCS projects operating in the power sector by the end of
the decade. Their progression to operation would add experience in the
dedicated geological storage of CO2 and see operational large-scale CCS
activity extend to China for the first time.
2014 saw commercial deployment in the power sector become a
reality and we can look forward to a further expansion across a diverse range
of industries in the coming years.
The coming year
Tehnopedia.net "Structure owned by the object is determined by the carbon content. In the low-carbon steel, the structure is dominated by the ferrite and pearlite is followed by a bit. At high carbon steel didominnasi by pearlite structure with little cementite. While the medium carbon steel, steel structure consisting of ferrite and pearlite with the comparison depends on the carbon content. The higher the carbon more perlitnya."
