  1. Bioenergy: Short status of the situation in Denmark Kathrine Hauge Madsen khm@landscentret.dk

  2. Content • Production of energy in Denmark • Biomass production for energy • Solid fuels • Transport fuels • Crops for biogas production • New energy policy announced by Danish government 19 January 07 11% of energy consump. 0,1% - 0-?% -

  3. North sea oil Oil production of primary energy Danish Energy Authority 2006

  4. Oil production, consumption and prediction for Denmark ? Technology Peter B. Nissen from Danish Energy Authority 2006

  5. Energy production in Denmark Danish Energy Authority 2006

  6. Available resources of waste/secondary biomass Danish Energy Authority 2006

  7. Straw in the Danish energy supply Danish Energy Authority 2006

  8. Prohibited to burn cereal grains in boilers larger than 250 kW • § 13. The board cannot approve coal, and products which may be use for food, including fish- and oilseed rape oil, surplus butter, cereals etc. as fuels for the public heating plants • Danish legislation concerning new projects in the public heating supply sector • Ethical concerns about use of food products in a world where some people starve

  9. Energy crops in Denmark 2006 (85-100.000) DFFE, November 06

  10. Willow (Salix) • Low level of nitrate leaching • Higher density of animals • Income from hunting • Different pattern of work load • Grows for 18-25 years • Harvested during winter • Reasonable economy • 300-2.200 DKK pr. ha • Option to use sewage sludge for fertilizing crop

  11. Market for wood chips and pellets in Denmark Wood chips Wood pellets Danish Energy Authority 2006

  12. 1. Generation known technology Cereals, maize, sugar beets, sugar cane 2. Generation under development Use of whole plants and waste products, but needs to be scaled up 1. vs. 2. Generation bioethanol Bio95 introduced 30 May 2006

  13. IBUS: 1 ton straw per hour Maxifuel pilot plant ethanol and biogas Pretreatment equipment Birgitte Ahring, DTU Anne Belinda Thomsen, Risø

  14. Biogas plants in Denmark • 4-5% of the Danish slurry production • 19 Centralized plants • 60 farm scale plants • Guarantied price on electricity produced • 0.60 DKK per kWh ~ 0.08 € • 0.45 DKK per kg dry matter • Limited amounts of organic waste • Interest for energy crops Jens Bo Holm-Nielsen

  15. Energy crops for biogas production – Contribution margin after machinery costs

  16. New energy plan 2025, 1 Renewable energy in percent of total energy consumption DK-2025 EU-2020

  17. New energy plan 2025, 2 • Renewable energy at least 30% by 2025 • More biomass for co-generated heat and electricity • Triple the use of biogas • Establish 50 large plants • Biofuels for transport 10% by 2020 • Before 2010 full scale research refineries for 2. generation bioethanol • Provided economical and environmentally sustainable technology is available…. • Waste/secondary products (waste, straw, slurry) • Currently debated in the Danish parliament

  18. New energy plan 2025, 3 Example: 30% renewable energy by 2025 Heat pumps, solar cells etc. Waste Biogas Straw and wood Windpower

  19. New energy plan 2025, 4 • DK total energy consumption constant • Same level as in the 1970s • Research/development doubled • 1 billion DKK • Aim: less dependency of fossil fuels • Currently negotiated with the Danish parliament
