It was also included as a key action, saving up to 900,000 tonnes of CO2 per annum, in the National Climate Change Strategy 2007-2012 published a month later. The overall Governmental objective was to reduce greenhouse gas emissions from power generation while introducing additional diversity into the fuel mix.
Bord na Móna is thus committed to the use of 300,000 tonnes per annum of biomass by 2015 at Edenderry (30% co-firing), with up to 500,000 tonnes required there by 2020
What is Biomass?
It is organic plant-based material, and represents the world’s fourth largest energy resource utilised (after oil, coal and gas). It is typically sourced from forestry and purpose grown energy crops.
Biomass is a sustainable energy resource that will play a major role in reducing Ireland’s CO2 emissions
Biomass and Bord na Móna
Co-firing with biomass commenced in earnest at Edenderry Station in 2008, and volumes have increased year on year with 200,000 tons consumed in 2012 and a planned 240,000 tons in the current year.
The supply of biomass for Edenderry is coming from three principal sectors:
Irish Forests: Both sawmill residues, such as woodchips and sawdust, and pulpwood from forestry thinnings in both log and chip form are currently been consumed in the Plant. In addition quantities of wood pellets from local producers are also being used.
Energy Crops: Perennial crops such as willow and Miscanthus. Miscanthus, however, can only be utilised in limited quantities (based on a 5% dilution factor with peat) owing to its higher chlorine content.
Imported Agri-residues: Palm kernel shells (PKS), almond shells, cocoa shells and olive stones form the remainder of our requirements.
Become a Biomass Supplier
As power generation at Edenderry will continue to 2030, Bord na Móna is willing to enter into 20 year contracts with farmers / producers to purchase harvested willow and supply forestry thinnings in either log or chip form to Edenderry Power Plant.
