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 http: //maps. seai. ie/bioenergy http: //www. seai. ie/Renewables/Bioenergy/
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.
