Modelling full-scale implementation of CCUS at large wood chip fuelled CHP plant in Denmark
This report presents a study the potential consequences of investing in CCUS technology at the Skærbæk CHP plant in Denmark. The plant is a major district heating provider that delivers heat to several towns in western Denmark, including Vejle, Kolding, Fredericia, and Middelfart. The plant currently uses approximately 550,000 tonnes of wood chips per year. The study is modelling the integration of CCUS technology to reduce the carbon footprint of the plant.
Key Lessons:
- Importance of scenario planning and evaluation: The study demonstrates that analysing different scenarios (BAU, CCS, CCUS) helps to understand the implications of investing in CCUS technology.
- Infrastructure and organizational needs are crucial: Integrating CCUS technology requires careful planning and implementation, particularly with regards to energy consumption, storage, and transportation.
- Market conditions and pricing play a significant role: The study’s results show that market conditions and prices for CO2 and energy affect the economic viability of CCUS technology.
- Complexity of integrating new systems into existing operations: Integrating CCUS technology into existing facilities is complex and requires careful coordination of processes and systems.
- Energy-intensive nature of CCUS processes: The study shows that CCUS processes are energy-intensive and influence the energy balances of the plant significantly.
