Abstract:
In Finland, the final consumption of energy in 2024 was 276 TWh and the share of space heating sector was about 28%. The district heating is the most common heating system in space heating, with the share of 45%. The heat is mainly produced with combustion technology, the share of 80%, and the main fuels from total heat supply, 35.5 TWh, are biomass: 48%, waste: 10%, peat: 6%, natural gas: 7%, oil: 3%, and coal: 6%. The share of renewables and recovered heat is over 70% in 2024. These days, there are conversations that the combustion technology in district heating should be transformed to non-combustion technology in future. The aim of the paper is to analyse how energy transition will affect to district heat production and volumes of biomass use. The use of biomass and new potential district heat production methods will be evaluated in the region of Kymenlaakso. One target is also to evaluate how the energy business will be developed in the future and what is the role of biomass in these circumstances. This is an ongoing study, and detailed results will be available later in 2025. There are many project ideas for energy transition in the region of Kymenlaakso. Now it is look like that the most promising alternatives are secondary heat utilisation from datacentres in city of Kouvola and hydrogen production in city of Kotka. In both cases, the secondary heat will be upgraded by heat pump, and produced heat recover the combustion of biomass and peat. The possibility of utilising secondary heat in district heating and the existing electricity network connections were important benefits in investment plans and locations. New technologies reduce to use of forest biomass, but forest biomass will have important role because of to replace to use of peat. Also, forest biomass will be played more important role in domestic supply security issues. The comprehensive information from regional energy transition helps different actors to recognize declining options and new business possibilities in future.
