1 Utilizing resources that otherwise would have been lost- Industrial surplus heat Charlotta Abrahamsson Swedish District Heating Association 1

2 District Heating as we see it Heat market Industrial Waste Heat Bio Mass? Energy from Waste Fuel production Fossil Fuels, peak load Combined Heat and Power EuroHeat and Power, Venice

3 Utilizing energy that otherwise would have been lost: Waste to Energy CHP Bio- Refineries CHP, fuel production, pellets, Industrial surplus heat Will we produce heat in the future? or just collect/connect heat and heatsources. 3

4 Heat supply to the Swedish district heating systems with source of origin 100% Heat supply to the Swedish district heating systems with source of origin 90% Electricity 80% 70% 60% Fossil fuels, direct use 50% 40% 30% 20% 10% 0% Renewables, direct use Recycled heat from CHP, waste and industries Source: Prof. Sven Werner 4

5 What is industrial surplus heat/ industrial waste heat? Heat from an industrial process of a temperature, high enough to direct use in the DH system. Heat with no use within the industry. The industries own energy use should always be optimized. Besides industrial surplus heat, industries can deliver heat of lower temperature where heat pumps is necessary and waste from industrial process; gases or solid fuels. 5

6 Study of potential for Industrial Surplus Heat in Sweden Spring 2009, ÅF-Consult Statistically calculated potential based on deliveries today and energy use per sector Corrected potential based on interviews 6

7 Surplus heat deliveries per industry in Sweden Pulp, paper and paper products Coke, refined petroleum products and nuclear fuel Chemicals and chemical products Basic metals Wood and wood products Food products and beverages Other manufacturing industries 7

8 Potential for surplus heat deliveries in Sweden: 8 TWh (today 4 TWh) Potential 0.00 Source: ÅF-Consult 8

9 Limitations? Annual variations Geographic location Other DH heat sources, CHP and energy from waste Investments and risks Financial crises 9

Iron and steal Man. of non-iron metals Casting of iron and metal Other manufacturing industry * Cooling of product means cooling from higher temperature to ambient temperature ** Freezing/cooling of product means cooling to a temperature lower than ambient temperature Cold-keeping Surplus steam Chemical reactions Drying Cooling of exhaust gases Cooling of product Evaporation / Condensation EuroHeat and Power, Venice /28/

11 Factors for successful collaborations Relations win-win Long term agreements Share the profit and the risk Educate operating staff Focus on the project s benefits Lower fuel consumption, environment, lower DH costs, PR - green profile 11

12 Lindesberg -10 years of Industrial Surplus Heat Local pulp and board plant inhabitants 85 % is provided by waste heat 12

13 Environmental improvements due to Surplus Heat utilization 100% 80% 60% 40% 20% Biomass Surplus heat Electricity Butane Fuel oil % Without Surplus heat With Surplus heat Without Surplus heat With Surplus heat CO2 ton/year NOX kg/year Electricity MWh/year The heat is transported from Frövifors Bruk to Frövi, Vedevåg and Lindesberg over an 18 km long transmission pipeline.

14 Industries, not only supplier of surplus heat One example of industrial customers: Swedish Honey producer use District Heating in it s process. Reducing use of oil and costs, and at the same time increasing capacity! 14

15 Potential in Europe? EJ EU25 + ACC4 + EFTA3 during 2003 Total Primary Energy Supply = 81,1 EJ CHP! Industrial surplus heat! Waste to energy! Losses in the energy transformation sector Losses in end use Combustible Renewables and Wast Solar/Wind/Other Geothermal Hydro Nuclear Natural Gas Petroleum Products Coal and Coal Products 10 0 Total Primary Energy Supply Total Final Consumption Total End Use (estimated) Transportation Electricity Heat 15

16 Utilizing energy resources that otherwise would have been lost? Energy efficient systems Climate, environment, customers, profit Will we produce heat in the future? Yes, at least in the near future. It is equally important to utilize energy already in the system, as using new renewable energy! 16
