Green Gas Certification Scheme Ciaran Burns 17 November 2016 GGCS - - PowerPoint PPT Presentation

Overview of the Green Gas Certification Scheme Ciaran Burns 17 November 2016

GGCS outline

• GGCS tracks commercial transactions of grid injected

biomethane through the supply chain

• Each unit of green gas injected into the grid displaces

the need for a unit of conventional gas

• Unique identifiers ensure there is no double-counting or

double-selling of green gas

• Certificates are valid for 3 years from the injection date,

at which point they are retired out of the system

Current scheme status

• 26 producers registered
• Capacity of producers 1.3 TWh per annum
• 22 suppliers registered
• Over 960 million kWh registered on the scheme since 2012
• 265 million kWh certificates sold
• 700 million kWh unsold (700 GWh)

Volume of certificates registered (GWh)

Total volume of units registered and number of producers registered

• Large volumes of the gas injected for 2016 not yet registered
• 2015 figures still increasing
• Waste water and food waste plants are larger but take longer to develop

• As it’s a new product several suppliers not yet active.
• Current energy supplier might already be a member

GGCS successes to date

• Low Carbon Emission Bus

– Green Gas Certificates (GGCs) proof of biomethane use – providing access to BSOG subsidy

• Recognition of Green Gas certificates under the GHG Protocol –

more later!

• Defra GHG reporting

– Inclusion of GGCs as reporting tool… – …Defra sitting on conclusion for 3 years now

• Explored use of GGCs as part of Zero Carbon Homes policy

– But Chancellor scrapped Government ambition on this in July 2015

• Buses paid 6p/km for using biomethane (BSOG). Settlement at end of year.
• 5 green energy suppliers now members in 2016
• Commercial suppliers now offering green tariffs

CO2 emission figure

• Biomass fuel used by RHI participants must meet a lifecycle

GHG emissions target of 34.8g CO2 eq/MJ of heat;

• Since all biomethane on the GGCS has received the RHI then it

is possible to say that all units of biomethane have emitted no more than 34.8g CO2 eq/MJ

• 125.28g CO2 eq/kWh
• These are Scope 3 emissions – More later from Syed, Sacha

and Sarah!!!

Looking Forward

• GGCs as a reporting tool in GHG Protocol

– International standards on how organisations should report the GHG emissions associated with their operations.

• Guarantees of Origin for Biopropane (BioLPG) with Calor Gas
• London Zero Carbon Homes policy

– ZCH standard to be introduced in London 1 October 2016 –already developer interest in green gas – One major development already committed to use of green gas certificates

• Use of green gas/green gas certificates in transport sector

– Considered in detail in REA ‘Use of gaseous fuels in transport’ REA report – Forthcoming RTFO will consider potential of grid-injected biomethane
