Sabhal Mòr Ostaig, Skye – Comparison of GHG emissions wood chip and pellets

Sabhal Mòr Ostaig, is a modern campus, part of the University of Highlands and Islands and is situated by the sea on the southern peninsula of Sleat on the Isle of Skye.  This case study aims to provide a brief summary of the potential differences in greenhouse gas emissions arising from the use of wood chips and wood pellets for the Kilbeg village site of Sabhal Mòr Ostaig.

Iceland: Bioenergy and Forestry in Treeless land

Iceland can be highlighted as an example of development of bioenergy from forest. Iceland has enormous geothermal heat reserves and a lot of hydropower. Iceland can be said to be the most developed country when we are talking about use of Renewable energy. More than 80 % of total energy consumption is based on renewable energy. The electricity price is Iceland is the lowest in whole Europe which make the use of biomass challenging. Still, wood energy can be an option.   The BioPAD project participated in a study tour of the forest supply chain in Iceland.

Kuhmo Local Bioenergy Production

Kuhmo is a city of 9,200 inhabitants on the eastern border of Kainuu, Finland, and like many other municipalities in Finland, Kuhmo utilizes a district heating network in the city center. Kainuu is one of the forerunner regions in the use of wood energy in Finland and the EU. This is based on excellent wood energy knowledge and production (in harvesting, logistics and production).  The total length of the district heating network is 28 km. The majority of buildings in the center of Kuhmo are connected to the district heating network.

Donegal Woodland Owners Society Ltd. (DWOSL)

DWOSL, based in Donegal, in the north-west of Ireland, are a wood fuel supply co-operative which supports and promotes sustainable forest management and timber marketing.  DWOSL entered the bioenergy Energy Supply Contract (ESCO) market, and this case study examines the supply chain from its members supplying fuel to the co-operative entering into agreements to supply energy to different buildings.

This is an on-going project which uses wood (logs) to generate bioenergy using gasification boilers. More information on this society can be found at http://www.donegalwoodlandowners.com/

Willow growing at Brook Hall Estate, L’Derry

John Gilliland is the Managing Partner of Brook Hall Estate, L’derry, Northern Ireland.  The Estate currently grows c.130 ha of short rotation willow and processes, dries and grades some 3,000 tonnes of dry woodchip each year.

In 1994, with help from AFBI (Agri Food & Bioscience Institute for NI) Loughgall, he planted his first willow on the farm. John has been closely involved with biomass production and utilization since that time and is now recognized throughout the world as one of the leading pioneers and innovators in this sector.

John is currently the Director of Original Heating. Original heating is the Regional Partner for the Austrian Biomass Boiler manufacturer for Ireland and Scotland. KWB is currently Germany’s best selling biomass boiler brand.

All heat for the farm, the farm houses, and driers now comes from a 300kW big bale boiler and 100kW KWB boiler, using the under and over sized woodchip, from the woodchip grading process. All electricity is wind electricity. Work continues with AFBI assistance to reduce the heat and electricity inputs.

Fortum Joensuu CHP plant (Kontiosuo)

This CHP plant is located in the Joensuu area of eastern Finland, and produces heat for c.40,000 inhabitants of Joensuu on a 180km district heating gird. Electricity is provided to the national grid. Wood and peat are used to create the bioenergy, as well as biogas from a landfill site, and reed canary grass.

Údarás na Gaeltachta

Údarás is a regional authority responsible for the economic, social and cultural development of the Gaeltacht areas in Ireland. They installed a 300kW woodchip boiler in 2012 at their head office in Furbo, c. 12 km from Galway city. The feedstock for this boiler is woodchip sourced from local suppliers.
