GRID Back-Up and BECCUS from Sustainable Biomass
CO2-Negative Capture or utilization from Existing and/or New Back-Up Oxyfuel Biomass Power Plants
1. Introduction
Nils-Peter Astrupgaard/Board of IDA Energy
On this conference day IDA Energi will highlight how biomass is sustainable, how CO2 from power plants can be utilized/stored and the need for larger power plants to support the grid:
- In Denmark there is a growing recognition to how sustainable biomass power plants with their rotating mass are important for keeping stable grid frequency and back-up the grid – in particular after recent winter weeks in ”Dunkelflaute” (No wind and solar).
- Through BECCS they will be carbon negative by reducing the atmospheric content of CO2. Conversion by BECCU climate neutral CO2 re-emits to the atmosphere through electro fuels (MeOH and SAF) or stores in possible products of plastics etc.
- Applicable technologies to BECCUS can be Amine-/and potassium carbonate capture processes - or even new power plants based on oxyfuel technology.
- Due to high and increasing Nord Pool Prices back-up from e.g. new oxyfuel based 400 MWe power units only needs 2.500 to 3.500 operating grid following hours a year in condensing mode to create a viable business plan – especially if a planned new capacity mechanism is introduced. Nord Pool spot price has over a year been above 1.000 DKK/MWh in DK2 for more than 3.000 hours.
- Sustainability of biomass is in question. Focus will be on how and when it is a sustainable fuel.
- BECCU is also a route to chemicals – thereby storing CO2 in products.

6. Biomass Power Plants are Important to support the Danish Grid.
Brian Vad Mathiesen / University of Aalborg
- Sustainable biomass from Danish suppliers should be prioritized only to production of back-up and stabilizing power in large high electric efficiency, fast ramping plants.
- Shorter yearly operational times not necessarily in CHP mode – but in condensing mode at significantly higher electric efficiency to support heat pumps and electric boilers.
Carsten Søgaard/Burmeister & Wain Energy
- Presentation of BWE oxyfuel biomass combustion technology
- How do BWE envisage future high electric efficiency applications in Denmark
- Anticipated fast response/ramp up behavior to support the dynamic grid
8. SHI-FW Fluid bed Oxyfuel-technology
Pasi Petra /Sumitomo SHI-FW
- Experience from multiple oxyfuel biomass gasification/combustion fluid bed plants
- How do SHI-FW envisage future high electric efficiency applications in Denmark
- Anticipated fast response/ramp up behavior to support the dynamic grid
9. Green plastic?
Carsten Rasmussen, Chief Operations Officer at the LEGO Group, said:
"Sourcing renewable e-methanol is part of our ambition to make LEGO® products more sustainable and reduce carbon emissions. Later this year, we will use the material to produce select LEGO elements - such as cross axles and connectors - while maintaining our high standards of safety, durability, and quality. This partnership is a powerful example of how collaboration and innovation across industries can accelerate meaningful progress.”
Dorethe Nielsen, VP Corporate Environmental Strategy, Novo Nordisk, said:
"This partnership enables us to take practical steps in decarbonising our supply chain and reducing the environmental impact of our products.”
10. Capacity Mechanisms?
ENS Stine?
11. Round up/Conclusions
- Open discussion and Q&A
- Round Up
