Renewable Gas for the large industry sector - The road to Ireland's low carbon economy

  1. Renewable Gas The key to Ireland’s Low Carbon Economy 1

  3. Contents Why Renewable Gas? Renewable Gas in Industry & Ireland’s Policies Benefits of Renewable Gas Sources of Renewable Gas Renewable Gas Forum Ireland First Industrial Renewable Gas Project
  4. • Gas Networks Ireland owns, operates, develops and maintains the natural gas network in Ireland. • World-class Modern Gas Network • Over 13,500Km: • 2,422Km Transmission Network • 11,288Km Distribution Network • More than 675,000 gas consumers • 650,000 homes • 25,000 businesses • Over 160 population centres • 19 counties Gas Networks Ireland
  5. • Network with Abundant Capacity • Secure and Reliable • Potential for over 50 injection points for renewable gas • Can deliver the same strong clean product, but now it can be Green also. Network potential for large industry sector
  6. Why Renewable Gas? Renewable Gas will enable Industry in Ireland to achieve our decarbonisation targets, without the need to re-invest in alternative infrastructure. Making renewable gas available to large energy users will play a vital role in helping Ireland meet its renewable heat (RES-H) targets of 12% by 2020.

  11. Sources of Renewable Gas • Renewable gas can be produced by anaerobic digestion (AD), gasification and power to gas (P2G) technologies • Available feedstock for anaerobic digestion ‒ Organic waste and residues ‒ Agricultural slurries ‒ Additional grass (in excess of livestock requirements) • Emerging sources of renewable gas such as ‒ Power to gas (H2 produced from curtailed electricity and catalytic/biological methanation) ‒ Gasification of wood biomass with catalytic/biological methanation ‒ It is estimated that these resources could add approximately 10,000 GWh/annum of renewable gas Assessed potential renewable gas sources in Ireland 0 10,000 20,000 30,000 40,000 50,000 60,000 70,000 80,000 Potential Renewable Gas Resource Current natural gas demand Grass Agricultural Manure Natural Gas demand Organic Waste Emerging Sources

Funded by SFI & GNI Researchers: Richard O’Shea, Prof’ Jerry Murphy • In excess of Harvest 2020 fodder demand • Teagasc study: “How much grassland biomass is available in Ireland in excess of livestock requirements?” by McEniry et al. 2013 • Up to 12.2 million tonnes of dry matter could be achieved even when allowing for “Food Harvest 2020” targets ~ 54,800 GWh/annum renewable gas. Analysis of Grass Feedstock
  14. • Solid - wood biomass ‒ “Transport distances, cultivation inputs and process utilities supply are the parameters which have the strongest influence on the final result. Furthermore, the GHG savings presented (especially the ones relative to power production) are subject to the choice of final energy conversion efficiency. A higher conversion efficiency, which for example can be achieved in co-firing application in existing power plants, would allow the majority of pathways to exceed 70% GHG savings.” • Gaseous – biogas / biomethane ‒ Biogas and biomethane produced from wet manure benefits greatly from the emission credits due to avoided GHG emissions from the alternative manure management. Consequently, GHG savings of above 100% are possible in many plant configurations. ‒ Co-digestion – optimise gas production while maximising carbon savings Sustainability & Carbon Balance
  15. GHG savings from fuel sources • AD of cattle manure avoids methane and nitrous oxide emissions from manure storage ~12% of agricultural GHG emissions in Ireland • Additional carbon credits come from improved manure management resulting in GHG savings (Total GHG savings up to 239% c.f. natural gas) • Multiple options to achieve 100% GHG savings by co- digestion with manure e.g. ‒ 100% GHG savings from 58% natural gas and 42% manure derived renewable gas Note: GHG emissions taken from EU JRC Science and Policy report on “Solid and gaseous bioenergy pathways: input values and GHG emissions”.

  16. Renewable Gas Supply Chain
  17. 17 • Mature and proven technologies – over 17,000 anaerobic digester have been built in EEA (2014) • Transitioning from small remote electricity generation to larger grid injection facilities • State policies/prioritisation and incentives transitioning to renewable gas for heat and CHP consuming industries. Renewable Gas in Europe
  18. 18 Ireland is currently one of the few countries in EEA with no support mechanisms for renewable gas Current Consultations and Schedule: Renewable Energy Policy in Ireland Draft Bioenergy Plan (2014) Phase 1 of 3 consultations on a Renewable Heat Incentive (RHI) and Renewable Electricity Supports (RES) Recommendations to the Government in Q4 2016 Support measures are likely to require State Aid approval of the EC which may take 6 months Supports to be implemented mid-late 2017 (estimate) “The RHI is focused on the large industrial non-emissions trading scheme(ETS) sector.” (DCENR, 2015)
