Your choices:
1 Fuel: liquid; 2 Process heat; 3 Residual oils/fats
| 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 |
| Biomass (solid) | Electricity | Process cooling (< 0 °C) |
| Geothermal | Fuel: Gaseous | 2 Process heat/steam (50 - 150 °C) |
| Sunshine | 1 Fuel: Liquid | 2 Process heat (150 - 1000 °C) |
| Water | Fuel: Solid | 2 Process heat (> 1000 °C) |
| Wind | Local cooling (ind. house) | Transport |
| 3 Residual oils/fats etc | Local heating (ind. house) |
Unless taxation and other economic incitements radically change, there will be one major reason for a process industry to switch from fossil fuel to liquid biofuel, and that is to strengthen the companies' green profile.
For biodiesel, the current world production amounts to some 20 million m3 of FAME per annum, the main part of which is produced from palm oil, soy, rapeseed oil and waste oil/fat, where the latter resources is so far only minor.
There may be reason to consider the palm oil extraction and its ecological consequences prior to taking a decision to replace the use of fossil fuel oil with a large-scale use of FAME.
