Biomass

There is a growing interest in using biomass as energy carrier, for instance for heat production, electricity production, transport fuel or as a feedstock for the chemical industry. However, biomass is often grown at the expense of food crops and stimulates deforestation. Careful consideration is required when using large amounts of biomass. We've updated the modelling of biomass streams in the ETM in 2019 in close collaboration with Gasunie, GasTerra, TKI Nieuw Gas and TNO. TNO supported this project by researching all required data.

Modelling principals

There are many different biomass resource streams; too many to model each one individually. Therefore we choose to distinguish these four biomass categories:

  • Wet biomass: residues from the food and beverage industry, agricultural residual streams, sewage sludge, aquatic biomass, cultivated grain products, etc.
  • Dry biomass: residual streams from forestry (tree tops, stumps, bark, branches), recycled waste wood, residual streams from agriculture (straw), and fast-growing bio-energy crops (elephant grass, willow, poplar)
  • Oil-containing biomass: rapeseed, sunflower seeds, oil palm, used frying fats.
  • Biogenic waste

TNO researched the potential of each biomass category for each country modelled in the ETM. When biomass demand exceeds this potential, then biomass will be imported from outside the region. For the Netherlands TNO researched the potentials in great detail. The potentials of over 30 biomass streams have been quantified and are shown in the last table of this document. The ETM allows users to adjust maximum biomass potentials for each biomass category with these sliders:

Biomass potential sliders

The set potentials are shown in the "Biomass demand and potential" chart along with the total demand of each biomass category. This gives the user a feeling of how much biomass is still regionally available.

Biomass demand and potential

Biomass can be used in different places throughout the model:

  • as green gas in the gas network
  • in biomass heaters for (local) heat networks
  • as transport fuel: bio-ethanol, biodiesel, bio-LNG and biokerosene
  • as co-firing in coal plants
  • as biocoal or bio-oil in power plants
  • to produce hydrogen through gasification

To get a quick overview of all future biomass streams and conversions, there is a sankey-chart visualizing these:

Users can adjust the costs of biofuels with sliders for greengas, biogas, wood, biodiesel and bio-ethanol. The costs that are used in the present year are researched by TNO:

Green gas production costs

TNO has researched the production cost for greengas producing technologies:

UnitWet gasification (SCW)Dry gasificationAnaerobic digestion
Efficiency%707048
Production costsEUR/MWh41.3375.7963.57
Input capacityMW input20708.33
Investment costsEUR191304.7
Fixed yearly O&M costsEUR/jaar39.50.23

Caution: the production costs of green gas are not optimized; this is mainly the case for the gasification technologies. Since these technologies are fairly new, there are not many practical examples on which the costs are based.

Dutch biomass potential

TNO has researched the potential biomass production in the Netherlands for 2030:

These total potentials originate from the underlying biomassa streams depicted below (sorry, in Dutch only):
