Gas CCS in the UK - Tom Snow at the UKCCSRC Gas CCS Meeting University of Sussex 25 June 2014
In addition the possible climate change impact of CO2 emissions from natural gas power generation has become of increasing importance with recent shale gas resource discoveries in the UK as pointed out in evidence from the Prime Minister to a UK Parliament committee on 14 Jan 2014 [1] ldquoMy nervousness about being too frank about the future (carbon budget review) is simply down to the issue about carbon capture and storage and the role that gas will play in futurerdquo It is now accepted that most of UK CCS deployment through new plants or retrofits is likely to take place in the 2020s httpdataparliamentukwrittenevidenceWrittenEvidencesvcEvidencePdf5219

FEED announced 30 June 2005 project cancelled mid 2007 when coal CCS needed instead in response to a (predicted) dash for coal after big increases in relative gas prices
Despite uncertainties in reserve sizes it is clear that if we burn all the fossil fuels or even half of the remaining reserves we will send the planet toward an ice-free state with sea level about 250 feet higher than today It would take time for complete ice sheet disintegration to occur but a chaotic situation would be created with changes occurring out of control of future generations
Oil may already be about half depleted ie the world may be close to peak oil production (implying that the IPCC estimate of reserves is closer to the truth than the EIA estimate) In either case common sense suggests that the largest oil pools will be exploited and the carbon dioxide which is emitted mainly from tailpipes will end up in the atmosphere
Gas the least carbon intensive and cleanest burning fossil fuel also surely will be exploited
The obvious conclusion is that the only practical way to avoid climate catastrophe is to terminate emissions from the largest fossil fuel source coal the dirtiest of the fossil fuels If coal emissions are phased out between 2010 and 2030 global fossil fuel emissions would begin to fall rapidly as shown in the chart below

The Queenrsquos Speech on November 18 2009 included Energy Bill with funding for CCS
9 April 2010 Energy Bill receives Royal Assent Originally specified coal but Act amended to
not specify fuels receiving levy support (but levy dropped after May 2010 election)

I believe Peterhead represents the best site in the UK for a gas CCS project and I hope that our submission to the government will be successfulrdquo
SSE chief executive Ian Marchant said ldquoIf long-term targets for reducing emissions are to be met CCS technology is going to have to apply as widely as possible This means gas-fired power stations as well as coal

Electricity Market Reform (EMR) White Paper 2011 Planning Our Electric Future A White Paper for Secure Affordable and Low-carbon Electricity 12 July 2011 The White Paper sets out key measures to attract investment reduce the impact on consumer bills and create a secure mix of electricity sources including gas new nuclear renewables and carbon capture and storage ldquoCreates a level playing field for low-carbon electricityrdquo paid for by Feed-in Tariffs with a Contract for Difference
BBC News 19 October 2011
Plans for the UKs first carbon capture project at the Longannet power station in Fife have been scrapped the energy secretary has confirmed
Chris Huhne announced the failure to reach a deal with power companies to capture carbon dioxide emissions at the plant and pipe them under the sea
Mr Huhne blamed problems with the length of pipeline needed
But he said the government hoped other schemes could work indicating interest at Peterhead in Aberdeenshire
A pound1bn project to tum a Scottish power station into a world leader in climate change technology has collapsed

Costs include compression to 110 bar but not storage and transport costs These are very site-specific but indicative aquifer storage costs of
$10tonne CO2 would increase electricity costs for natural gas plants by about 04 ckWh and for coal plants by about 08 ckWh
Coal price US$15GJ Natural Gas price US$ 3GJ LHV basis

IEAGHG (2006) CO2 capture as a factor in power station investment decisions Report No 20068 May 2006
The main features of post-combustion technology for natural gas-fired CCGTs are summarised below bull Significant land footprint with different estimates ranging between 9000 and 40000 square
metres for the capture equipment - requirement for available space in retrofit of existing plant
bull CO2 concentration in power station flue gases is typically 4 - so that large volumes of flue gases must be processed
bull Uses an organic solvent (Monoethylamine MEA is most usual) which captures CO2 when in solution using a scrubber tower in contact with the flue gases
bull Incorporates circulation of the rich solution of MEA with absorbed CO2 to a stripperlsquo tower where it is reheated leading to release of CO2 and production of lean solvent solution for return to the scrubber
bull MEA is degraded by contact with NO2 or SO2 These pollutants must therefore by reduced to low concentration level ( 1 to 20 ppm for NO2 and 1 to 10 ppm for SO2) in order to result in an acceptable life for the MEA For gas-fired plant only NOx levels generally require reduction
bull Continual replacement of MEA is a significant operating cost bull As a result of the above two points the power plant needs to be equipped with Selective Catalytic
Reduction (SCR) of NOx in the process of retrofitting for CO2 capture or during the design of new plants
bull Addition of capture to a CCGT plant incurs an efficiency penalty of around 60-82 percentage points LHV (IEAGHG 2004)

Despite uncertainties in reserve sizes it is clear that if we burn all the fossil fuels or even half of the remaining reserves we will send the planet toward an ice-free state with sea level about 250 feet higher than today It would take time for complete ice sheet disintegration to occur but a chaotic situation would be created with changes occurring out of control of future generations
Oil may already be about half depleted ie the world may be close to peak oil production (implying that the IPCC estimate of reserves is closer to the truth than the EIA estimate) In either case common sense suggests that the largest oil pools will be exploited and the carbon dioxide which is emitted mainly from tailpipes will end up in the atmosphere
Gas the least carbon intensive and cleanest burning fossil fuel also surely will be exploited
The obvious conclusion is that the only practical way to avoid climate catastrophe is to terminate emissions from the largest fossil fuel source coal the dirtiest of the fossil fuels If coal emissions are phased out between 2010 and 2030 global fossil fuel emissions would begin to fall rapidly as shown in the chart below

IEAGHG (2006) CO2 capture as a factor in power station investment decisions Report No 20068 May 2006
The main features of post-combustion technology for natural gas-fired CCGTs are summarised below bull Significant land footprint with different estimates ranging between 9000 and 40000 square
metres for the capture equipment - requirement for available space in retrofit of existing plant
bull CO2 concentration in power station flue gases is typically 4 - so that large volumes of flue gases must be processed
bull Uses an organic solvent (Monoethylamine MEA is most usual) which captures CO2 when in solution using a scrubber tower in contact with the flue gases
bull Incorporates circulation of the rich solution of MEA with absorbed CO2 to a stripperlsquo tower where it is reheated leading to release of CO2 and production of lean solvent solution for return to the scrubber
bull MEA is degraded by contact with NO2 or SO2 These pollutants must therefore by reduced to low concentration level ( 1 to 20 ppm for NO2 and 1 to 10 ppm for SO2) in order to result in an acceptable life for the MEA For gas-fired plant only NOx levels generally require reduction
bull Continual replacement of MEA is a significant operating cost bull As a result of the above two points the power plant needs to be equipped with Selective Catalytic
Reduction (SCR) of NOx in the process of retrofitting for CO2 capture or during the design of new plants
bull Addition of capture to a CCGT plant incurs an efficiency penalty of around 60-82 percentage points LHV (IEAGHG 2004)

IEAGHG (2006) CO2 capture as a factor in power station investment decisions Report No 20068 May 2006
The main features of post-combustion technology for natural gas-fired CCGTs are summarised below bull Significant land footprint with different estimates ranging between 9000 and 40000 square
metres for the capture equipment - requirement for available space in retrofit of existing plant
bull CO2 concentration in power station flue gases is typically 4 - so that large volumes of flue gases must be processed
bull Uses an organic solvent (Monoethylamine MEA is most usual) which captures CO2 when in solution using a scrubber tower in contact with the flue gases
bull Incorporates circulation of the rich solution of MEA with absorbed CO2 to a stripperlsquo tower where it is reheated leading to release of CO2 and production of lean solvent solution for return to the scrubber
bull MEA is degraded by contact with NO2 or SO2 These pollutants must therefore by reduced to low concentration level ( 1 to 20 ppm for NO2 and 1 to 10 ppm for SO2) in order to result in an acceptable life for the MEA For gas-fired plant only NOx levels generally require reduction
bull Continual replacement of MEA is a significant operating cost bull As a result of the above two points the power plant needs to be equipped with Selective Catalytic
Reduction (SCR) of NOx in the process of retrofitting for CO2 capture or during the design of new plants
bull Addition of capture to a CCGT plant incurs an efficiency penalty of around 60-82 percentage points LHV (IEAGHG 2004)

Gas CCS in the UK - Tom Snow at the UKCCSRC Gas CCS Meeting University of Sussex 25 June 2014
In addition the possible climate change impact of CO2 emissions from natural gas power generation has become of increasing importance with recent shale gas resource discoveries in the UK as pointed out in evidence from the Prime Minister to a UK Parliament committee on 14 Jan 2014 [1] ldquoMy nervousness about being too frank about the future (carbon budget review) is simply down to the issue about carbon capture and storage and the role that gas will play in futurerdquo It is now accepted that most of UK CCS deployment through new plants or retrofits is likely to take place in the 2020s httpdataparliamentukwrittenevidenceWrittenEvidencesvcEvidencePdf5219
Rt Hon David Cameron MP on natural gas and CCS Question 45 in ldquo14 Jan 2014 - Evidence from the Prime Minister 14 January 2014 ndash oral evidence

FEED announced 30 June 2005 project cancelled mid 2007 when coal CCS needed instead in response to a (predicted) dash for coal after big increases in relative gas prices
Despite uncertainties in reserve sizes it is clear that if we burn all the fossil fuels or even half of the remaining reserves we will send the planet toward an ice-free state with sea level about 250 feet higher than today It would take time for complete ice sheet disintegration to occur but a chaotic situation would be created with changes occurring out of control of future generations
Oil may already be about half depleted ie the world may be close to peak oil production (implying that the IPCC estimate of reserves is closer to the truth than the EIA estimate) In either case common sense suggests that the largest oil pools will be exploited and the carbon dioxide which is emitted mainly from tailpipes will end up in the atmosphere
Gas the least carbon intensive and cleanest burning fossil fuel also surely will be exploited
The obvious conclusion is that the only practical way to avoid climate catastrophe is to terminate emissions from the largest fossil fuel source coal the dirtiest of the fossil fuels If coal emissions are phased out between 2010 and 2030 global fossil fuel emissions would begin to fall rapidly as shown in the chart below

Gas CCS in the UK - Tom Snow at the UKCCSRC Gas CCS Meeting University of Sussex 25 June 2014
In addition the possible climate change impact of CO2 emissions from natural gas power generation has become of increasing importance with recent shale gas resource discoveries in the UK as pointed out in evidence from the Prime Minister to a UK Parliament committee on 14 Jan 2014 [1] ldquoMy nervousness about being too frank about the future (carbon budget review) is simply down to the issue about carbon capture and storage and the role that gas will play in futurerdquo It is now accepted that most of UK CCS deployment through new plants or retrofits is likely to take place in the 2020s httpdataparliamentukwrittenevidenceWrittenEvidencesvcEvidencePdf5219
Rt Hon David Cameron MP on natural gas and CCS Question 45 in ldquo14 Jan 2014 - Evidence from the Prime Minister 14 January 2014 ndash oral evidence

FEED announced 30 June 2005 project cancelled mid 2007 when coal CCS needed instead in response to a (predicted) dash for coal after big increases in relative gas prices
Despite uncertainties in reserve sizes it is clear that if we burn all the fossil fuels or even half of the remaining reserves we will send the planet toward an ice-free state with sea level about 250 feet higher than today It would take time for complete ice sheet disintegration to occur but a chaotic situation would be created with changes occurring out of control of future generations
Oil may already be about half depleted ie the world may be close to peak oil production (implying that the IPCC estimate of reserves is closer to the truth than the EIA estimate) In either case common sense suggests that the largest oil pools will be exploited and the carbon dioxide which is emitted mainly from tailpipes will end up in the atmosphere
Gas the least carbon intensive and cleanest burning fossil fuel also surely will be exploited
The obvious conclusion is that the only practical way to avoid climate catastrophe is to terminate emissions from the largest fossil fuel source coal the dirtiest of the fossil fuels If coal emissions are phased out between 2010 and 2030 global fossil fuel emissions would begin to fall rapidly as shown in the chart below

IEAGHG (2006) CO2 capture as a factor in power station investment decisions Report No 20068 May 2006
The main features of post-combustion technology for natural gas-fired CCGTs are summarised below bull Significant land footprint with different estimates ranging between 9000 and 40000 square
metres for the capture equipment - requirement for available space in retrofit of existing plant
bull CO2 concentration in power station flue gases is typically 4 - so that large volumes of flue gases must be processed
bull Uses an organic solvent (Monoethylamine MEA is most usual) which captures CO2 when in solution using a scrubber tower in contact with the flue gases
bull Incorporates circulation of the rich solution of MEA with absorbed CO2 to a stripperlsquo tower where it is reheated leading to release of CO2 and production of lean solvent solution for return to the scrubber
bull MEA is degraded by contact with NO2 or SO2 These pollutants must therefore by reduced to low concentration level ( 1 to 20 ppm for NO2 and 1 to 10 ppm for SO2) in order to result in an acceptable life for the MEA For gas-fired plant only NOx levels generally require reduction
bull Continual replacement of MEA is a significant operating cost bull As a result of the above two points the power plant needs to be equipped with Selective Catalytic
Reduction (SCR) of NOx in the process of retrofitting for CO2 capture or during the design of new plants
bull Addition of capture to a CCGT plant incurs an efficiency penalty of around 60-82 percentage points LHV (IEAGHG 2004)

Despite uncertainties in reserve sizes it is clear that if we burn all the fossil fuels or even half of the remaining reserves we will send the planet toward an ice-free state with sea level about 250 feet higher than today It would take time for complete ice sheet disintegration to occur but a chaotic situation would be created with changes occurring out of control of future generations
Oil may already be about half depleted ie the world may be close to peak oil production (implying that the IPCC estimate of reserves is closer to the truth than the EIA estimate) In either case common sense suggests that the largest oil pools will be exploited and the carbon dioxide which is emitted mainly from tailpipes will end up in the atmosphere
Gas the least carbon intensive and cleanest burning fossil fuel also surely will be exploited
The obvious conclusion is that the only practical way to avoid climate catastrophe is to terminate emissions from the largest fossil fuel source coal the dirtiest of the fossil fuels If coal emissions are phased out between 2010 and 2030 global fossil fuel emissions would begin to fall rapidly as shown in the chart below

BBC News 19 October 2011
Plans for the UKs first carbon capture project at the Longannet power station in Fife have been scrapped the energy secretary has confirmed
Chris Huhne announced the failure to reach a deal with power companies to capture carbon dioxide emissions at the plant and pipe them under the sea
Mr Huhne blamed problems with the length of pipeline needed
But he said the government hoped other schemes could work indicating interest at Peterhead in Aberdeenshire

$10tonne CO2 would increase electricity costs for natural gas plants by about 04 ckWh and for coal plants by about 08 ckWh

IEAGHG (2006) CO2 capture as a factor in power station investment decisions Report No 20068 May 2006
The main features of post-combustion technology for natural gas-fired CCGTs are summarised below bull Significant land footprint with different estimates ranging between 9000 and 40000 square
metres for the capture equipment - requirement for available space in retrofit of existing plant
bull CO2 concentration in power station flue gases is typically 4 - so that large volumes of flue gases must be processed
bull Uses an organic solvent (Monoethylamine MEA is most usual) which captures CO2 when in solution using a scrubber tower in contact with the flue gases
bull Incorporates circulation of the rich solution of MEA with absorbed CO2 to a stripperlsquo tower where it is reheated leading to release of CO2 and production of lean solvent solution for return to the scrubber
bull MEA is degraded by contact with NO2 or SO2 These pollutants must therefore by reduced to low concentration level ( 1 to 20 ppm for NO2 and 1 to 10 ppm for SO2) in order to result in an acceptable life for the MEA For gas-fired plant only NOx levels generally require reduction
bull Continual replacement of MEA is a significant operating cost bull As a result of the above two points the power plant needs to be equipped with Selective Catalytic
Reduction (SCR) of NOx in the process of retrofitting for CO2 capture or during the design of new plants
bull Addition of capture to a CCGT plant incurs an efficiency penalty of around 60-82 percentage points LHV (IEAGHG 2004)

Electricity Market Reform (EMR) White Paper 2011 Planning Our Electric Future A White Paper for Secure Affordable and Low-carbon Electricity 12 July 2011 The White Paper sets out key measures to attract investment reduce the impact on consumer bills and create a secure mix of electricity sources including gas new nuclear renewables and carbon capture and storage ldquoCreates a level playing field for low-carbon electricityrdquo paid for by Feed-in Tariffs with a Contract for Difference
BBC News 19 October 2011
Plans for the UKs first carbon capture project at the Longannet power station in Fife have been scrapped the energy secretary has confirmed
Chris Huhne announced the failure to reach a deal with power companies to capture carbon dioxide emissions at the plant and pipe them under the sea
Mr Huhne blamed problems with the length of pipeline needed
But he said the government hoped other schemes could work indicating interest at Peterhead in Aberdeenshire
A pound1bn project to tum a Scottish power station into a world leader in climate change technology has collapsed
IEAGHG (2006) ELECTRICITY COSTS FOR CAPTURE PLANTS
IEAGHG (2006) CO2 capture as a factor in power station investment decisions Report No 20068 May 2006
Costs include compression to 110 bar but not storage and transport costs These are very site-specific but indicative aquifer storage costs of
$10tonne CO2 would increase electricity costs for natural gas plants by about 04 ckWh and for coal plants by about 08 ckWh
Coal price US$15GJ Natural Gas price US$ 3GJ LHV basis

IEAGHG (2006) CO2 capture as a factor in power station investment decisions Report No 20068 May 2006
The main features of post-combustion technology for natural gas-fired CCGTs are summarised below bull Significant land footprint with different estimates ranging between 9000 and 40000 square
metres for the capture equipment - requirement for available space in retrofit of existing plant
bull CO2 concentration in power station flue gases is typically 4 - so that large volumes of flue gases must be processed
bull Uses an organic solvent (Monoethylamine MEA is most usual) which captures CO2 when in solution using a scrubber tower in contact with the flue gases
bull Incorporates circulation of the rich solution of MEA with absorbed CO2 to a stripperlsquo tower where it is reheated leading to release of CO2 and production of lean solvent solution for return to the scrubber
bull MEA is degraded by contact with NO2 or SO2 These pollutants must therefore by reduced to low concentration level ( 1 to 20 ppm for NO2 and 1 to 10 ppm for SO2) in order to result in an acceptable life for the MEA For gas-fired plant only NOx levels generally require reduction
bull Continual replacement of MEA is a significant operating cost bull As a result of the above two points the power plant needs to be equipped with Selective Catalytic
Reduction (SCR) of NOx in the process of retrofitting for CO2 capture or during the design of new plants
bull Addition of capture to a CCGT plant incurs an efficiency penalty of around 60-82 percentage points LHV (IEAGHG 2004)

I believe Peterhead represents the best site in the UK for a gas CCS project and I hope that our submission to the government will be successfulrdquo
SSE chief executive Ian Marchant said ldquoIf long-term targets for reducing emissions are to be met CCS technology is going to have to apply as widely as possible This means gas-fired power stations as well as coal

Electricity Market Reform (EMR) White Paper 2011 Planning Our Electric Future A White Paper for Secure Affordable and Low-carbon Electricity 12 July 2011 The White Paper sets out key measures to attract investment reduce the impact on consumer bills and create a secure mix of electricity sources including gas new nuclear renewables and carbon capture and storage ldquoCreates a level playing field for low-carbon electricityrdquo paid for by Feed-in Tariffs with a Contract for Difference
BBC News 19 October 2011
Plans for the UKs first carbon capture project at the Longannet power station in Fife have been scrapped the energy secretary has confirmed
Chris Huhne announced the failure to reach a deal with power companies to capture carbon dioxide emissions at the plant and pipe them under the sea
Mr Huhne blamed problems with the length of pipeline needed
But he said the government hoped other schemes could work indicating interest at Peterhead in Aberdeenshire

IEAGHG (2006) CO2 capture as a factor in power station investment decisions Report No 20068 May 2006
The main features of post-combustion technology for natural gas-fired CCGTs are summarised below bull Significant land footprint with different estimates ranging between 9000 and 40000 square
metres for the capture equipment - requirement for available space in retrofit of existing plant
bull CO2 concentration in power station flue gases is typically 4 - so that large volumes of flue gases must be processed
bull Uses an organic solvent (Monoethylamine MEA is most usual) which captures CO2 when in solution using a scrubber tower in contact with the flue gases
bull Incorporates circulation of the rich solution of MEA with absorbed CO2 to a stripperlsquo tower where it is reheated leading to release of CO2 and production of lean solvent solution for return to the scrubber
bull MEA is degraded by contact with NO2 or SO2 These pollutants must therefore by reduced to low concentration level ( 1 to 20 ppm for NO2 and 1 to 10 ppm for SO2) in order to result in an acceptable life for the MEA For gas-fired plant only NOx levels generally require reduction
bull Continual replacement of MEA is a significant operating cost bull As a result of the above two points the power plant needs to be equipped with Selective Catalytic
Reduction (SCR) of NOx in the process of retrofitting for CO2 capture or during the design of new plants
bull Addition of capture to a CCGT plant incurs an efficiency penalty of around 60-82 percentage points LHV (IEAGHG 2004)

IEAGHG (2006) CO2 capture as a factor in power station investment decisions Report No 20068 May 2006
IEAGHG (2006) CO2 capture as a factor in power station investment decisions Report No 20068 May 2006
The main features of post-combustion technology for natural gas-fired CCGTs are summarised below bull Significant land footprint with different estimates ranging between 9000 and 40000 square
metres for the capture equipment - requirement for available space in retrofit of existing plant
bull CO2 concentration in power station flue gases is typically 4 - so that large volumes of flue gases must be processed
bull Uses an organic solvent (Monoethylamine MEA is most usual) which captures CO2 when in solution using a scrubber tower in contact with the flue gases
bull Incorporates circulation of the rich solution of MEA with absorbed CO2 to a stripperlsquo tower where it is reheated leading to release of CO2 and production of lean solvent solution for return to the scrubber
bull MEA is degraded by contact with NO2 or SO2 These pollutants must therefore by reduced to low concentration level ( 1 to 20 ppm for NO2 and 1 to 10 ppm for SO2) in order to result in an acceptable life for the MEA For gas-fired plant only NOx levels generally require reduction
bull Continual replacement of MEA is a significant operating cost bull As a result of the above two points the power plant needs to be equipped with Selective Catalytic
Reduction (SCR) of NOx in the process of retrofitting for CO2 capture or during the design of new plants
bull Addition of capture to a CCGT plant incurs an efficiency penalty of around 60-82 percentage points LHV (IEAGHG 2004)
