Overview – policy drivers
• Government White Paper – Delivering a
Sustainable Energy Future for Ireland, 2007
– Set renewable energy targets 2020
• 12% RES-H, 10% RES-T, RES-E 33% (to 40% 2008)
• RES: 16% target
– 30% co-firing with biomass at the 3 peat power
plants (2015)
– 800 MW of CHP by 2020
• Emphasis on biomass (AD-CHP/Biomass-CHP)
• National Bioenergy Action Plan 2007
– Contains 50 actions including targets for biomass
heating etc.
• National Renewable Energy Action Plan
– Launched June 2010
– The Renewables Directive requires each Member
State to produce an action plan showing how they
intend to meet their renewable obligations
REFIT
•
Renewable Energy Feed In Tariff (launched 2010)
– Biomass-CHP
• 14 ct/kWh ≤ 1.5 MW (Maximum Export Capacity)
• 12 ct/kWh > 1.5 MW (MEC)
– Anaerobic-digestion
• 10 ct/kWh > 500 kW AD (non CHP)
• 11 ct/kWh ≤ 500 kW AD (non CHP)
• 13 ct/kWh > 500 kW AD CHP
• 15 ct/kWh ≤ 500 kW AD CHP
– “CHP utilising biomethane, displaced from the source of biomethane, will
qualify for REFIT on that portion of the fuel mix deriving from bioenergy”
(NREAP)
• 15 ct/kWh

2010)
•
Report by Bord Gais in support with E&Y, UCC, EPA, SEAI
•
Investigating the market overview and potential of
Biomethane in Ireland
•

(connected to 650,000 customers and recently
upgraded)
– 1.4m dwellings in Ireland in total
•
Conclusions of the report:
– Technology contributes to all RES target (esp. T and H)
– Realistic baseline scenario: 7.5% of natural gas can be
replaced by biomethane (2.6% of final energy demand)
– App. 200 upgrading digester estimated (long term)
– Recommendations to the government to drive that
particular technology
Bioenergy Geographical
Information System (BGIS)
Why a Bioenergy-GIS?
• BGIS = Bioenergy Geographical Information System
• BGIS enables geographic visualisation of Bioenergy data
– In coordination with Teagasc, Department of Agriculture etc.
• “Google based” system
• The bioenergy GIS helps us to answer the questions of:
– What (e.g. Energy Crops, demand etc.)?
– Where (where planted, where suitable)?
– How much is planted/available (e.g. ha, t)?
• That leads to:
– Demand analysis (industrial biomass boilers, WWTP)
– Resource analysis
– Scenario building (feasibility study)
http://www.seai.ie/Renewables/Bioenergy/
Resource location
Locate resources:
• SRC Willow
• Miscanthus
• Other energy crops
Demand:
• Residential and commercial
(granted) installations
• Large industrial biomass users
Bioenergy-GIS
Optimise supply chains
Match resources to demand
• Measure distances
• Cluster resources and endusers
• Analysis
Bioenergy-GIS
• The BGIS can assist with:
– Identifying opportunities
– Feasibility studies
– Supply chain optimisation

Summary
Summary Bioenergy (1)
Opportunities
•
During the last 2 years much development in the Bioenergy market
•
Bioenergy will play a significant role in the future energy market in
Ireland
– Potential to supply constant electricity, heat, gas, transport fuel
• Bioenergy contributes to all RE-targets
– Can be stored-dispatchable power
– Production close to demand (less transmission losses)
– Getting energy independent
•
National targets have to be achieved
– Electricity just 17% from gross final energy consumption (wind, wave)
– 10% electric vehicles contribute a portion to RES-T target (1.1% of 10%
target, study undertaken by UCC 2009)
•
New agricultural policy, landfill directive, landfill levy, nitrates directive,
legislation drive the market
•
Creating and supporting rural jobs and opportunities for several years
– Farmer harvesting energy, new opportunities
– Ongoing employment after construction (supply chain, operation,
maintenance)
Summary Bioenergy (2)
Opportunities
• Bioenergy in Ireland is a “Sleeping Giant”
– Very interesting market in the near future
• Ireland has a significant unexploited resource potential
for Bioenergy and AD
• High potential feedstock (agricultural residues,
forestry, energy crops etc.) and farming knowledge
• Support is available (EU projects, Leader groups, RD+D,
REFIT)
• Market update, reports, software available (BGIS,
literature on website)
– Ireland joined 4 IEA Bioenergy Task 2011 (e.g. Energy
from Biogas, UCC)
