The UK is pursuing carbon capture and storage (CCS) as a key part of its efforts to decarbonize its economy and energy sector while maintaining energy security and affordability. It has a comprehensive CCS program that includes a £1 billion capital competition to fund initial CCS projects, support for ongoing costs through contracts-for-difference, research and development funding to reduce costs, and international collaboration on knowledge sharing. The program aims to make CCS-equipped power plants cost competitive with other low-carbon technologies and establish CCS as a major part of the UK's low-carbon energy mix by 2030 and beyond.

huge economic prize for the UK in
its low carbon transition, cutting the
annual cost of meeting our carbon
targets by up to 1% of GDP by

Desired outcome:
“as a result of the
intervention, private
sector electricity
companies can take
investment decisions
to build CCS
equipped fossil-fuel
power stations, in the
early 2020s, without
Government capital
subsidy, at an agreed
CfD strike price that is
competitive with the
strike prices for other
low carbon
generation
technologies.”
Objective and timeline
7. £1bn Competition – Preferred Bidders
Peterhead
o A 340MW Post-combustion capture
retrofitted to part of an existing Combined
Cycle Gas Turbine power station at
Peterhead, Scotland.
o Storage offshore in Goldeneye depleted
gas field.
o Led by Shell and SSE.
White Rose
o An Oxyfuel capture project at a proposed
new 304MW fully abated supercritical coal-
fired power station on the Drax site in North
Yorkshire.
o Led by Alstom and involving Drax, BOC
and National Grid Carbon.
8. £1bn Competition – Reserve Bidders
Teeside Low Carbon
o Decarbonised syngas in new 330MWe net
CCGT, coal-based.
o Located on Teesside, North East England
with storage in depleted oil fields and a
saline aquifer.
o Proposed through a consortium led by
Progressive Energy involving GDF
SUEZ, Premier Oil, and BOC.
Captain Clean Energy
o A proposal for a new 570MW, fully abated
coal IGCC (pre-combustion) project.
o Located in Grangemouth, Scotland with
storage in offshore depleted gas fields.
o Led by Summit Power, with
Petrofac, National Grid and Siemens.
9. Electricity Market Reform (EMR)
• Long-term contracts that
reflect the value of low
carbon generation
• Feed-in Tariff Contract for
Difference
• A proposed Capacity
Mechanism
• A Carbon Price Floor
• An Emissions Performance
Standard
• £7.6bn Levy Control
Framework (LCF) in 2020/21
Government
Sets overall policy direction and sets out key parameters
System operator (National Grid)
Will advise government on contract parameters and administer the
arrangements
Investment in low-carbon generation also supported by
Carbon Price Floor & Emissions Performance Standard
Contracts to develop low carbon
generation –
contracts for difference
Market wide capacity contracts:
open to all forms of capacity
Existing wholesale market (plus small scale FiTs)
UK EMR Programme includes:
10. n
Contracts for Difference (CfDs)
Providing long term price stability
• CfD provides long-term revenue stability, lowering risk to
investors and costs to consumers
• Generator sells power, but receives a „top-up‟ payment
• Top-up pays the difference between the „Strike Price‟ and
the market price:
• Generator paid when market price below strike price
• But, generator pays back when market price is high
11. Triple lock
NPS, CPF and EPS
• National Policy Statement
for Energy (NPS) - No new
coal without CCS (min
300MW)
• Carbon Price Floor (CPF)
provides a stronger
carbon price to promote
investment in low-carbon
generation
• Emissions Performance
Standard (EPS) – 450g
CO2/kWh limit on carbon
emissions
• Long-term certainty
(“grandfathering” of limit
to 2045) for consented
plant
• Reviewed in the future –

Government and Industry and the
creation of new groups to drive
forward action.
