Your choices:
1 Process heat (> 1000 °C); 2 Electricity; 3 Biomass (solid)
| What is your resource? | What do you want to deliver? | What is the service the customer wants? |
| Biomass (digestible sludge) | District cooling | Comfortable indoor climate |
| Biomass (fermentable sludge) | District heating | Electricity |
| 3 Biomass (solid) | 2 Electricity | Process cooling (< 0 °C) |
| Geothermal | Fuel: Gaseous | Process heat/steam (50 - 150 °C) |
| Sunshine | Fuel: Liquid | Process heat (150 - 1000 °C) |
| Water | Fuel: Solid | 1 Process heat (> 1000 °C) |
| Wind | Local cooling (ind. house) | Transport |
| Residual oils/fats etc | Local heating (ind. house) |
Sufficiently large-scale electricity production from solid biomass should be contracted from CHP or tri-generation plants. For the contract to really strengthen the company's green profile it will be important to really follow up all steps in the supply chain:
- The electricity producing plant will have to have an efficiency exceeding 90%, so only CHP or tri-generation plants will be of interest.
- Ash recirculation systems should be in place.
- The volume of contracted electricity must be sufficient.
Finding contractors that fulfil these criteria is not too hard and doing that, the industrial process will readily qualify as being operated based on solid biomass.
