| 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 | 1 Fuel: Gaseous | 2 Process heat/steam (50 - 150 °C) |
| Sunshine | Fuel: Liquid | 2 Process heat (150 - 1000 °C) |
| Water | Fuel: Solid | 2 Process heat (> 1000 °C) |
| Wind | Local cooling (ind. house) | Transport |
| Residual oils/fats etc | Local heating (ind. house) |
Several high-temperature industrial processes, such as steel reheating furnaces, tunnel furnaces for the burning of building brick or glass tanks, will today be equipped with fossil gas burners.
In many cases, the reasons for this are the availability and reliability of the gas supply, combined with the ease of control inherent with gas combustion. As long as the gas quality and the quality of the delivery remain constant, the real origin of the gas will make no difference to the end user.
