Financing and realising energy efficiency and renewable energy projects in industry

Efficiency & renewable energy potential

Our challenge: Fossil fuels dominate

Fossil fuels, including natural gas, coal, fuel oil and others, supply:

  • >85% of industrial process heating

Biomass is the only significant renewable source supplying process heating (about 10%). 

Are there economical industrial energy efficiency opportunities?

 

Yes, energy efficiency offers myriad opportunities for a significant return on investment!

If EU industry invested in all economic energy efficiency measures (<5 yr simple payback), the average savings potential (MTOE) compared with business as usual is:

  • 5% of industrial final energy consumption by 2030 and 10.3% by 2050. (4)

 

The table shows business as usual consumption through 2030 and two economic energy savings scenarios for the same period. Every industrial sector has promising opportunities!

SectorBAU consumption (MTOE/yr)Economic potential <2yr payback (MTOE)Economic potential <5yr payback (MTOE)
Pulp and paper 37.3 1.1 (2.9%) 1.4 (3.8%)
Chemical  66.4 2.6 (4%) 3.2 (4.9%)
Food & beverage 26.4 1.4 (5.2%) 1.7 (6.5%)
Machinery 19.8 2.0 (10.5%) 2.5 (13.3%)

 MTOE: Million tonnes of oil equivalent

 

 

 

Renewable energy potential

There is high economical and technical potential for renewable systems to supply industrial thermal processes.

The temperature requirements of the industrial process is an important consideration when determining which renewable systems are appropriate: 

  • Solar thermal with tracking systems can supply up to 250°C (3)
  • Biogas systems with steam boilers can provide heat recovery up to 380°C
  • Biomass systems can supply process heating up to 2000°C.

 

Impact summary

Energy efficiency and renewables together could supply 60% of industrial process heating energy. That is the energy equivalent of about 86,400,000 mid-to-large size EU homes! 

 

While fossil fuels dominate the supply of process heating energy in Europe today, the potential for economical energy efficiency is:

  • 8-10% industrial final energy consumption savings by 2050 (payback <5 yrs) 

  • 154-192 terawatt hour (TWh) energy savings (4)

And the renewable energy technical potential for solar thermal, biogas, and biomass systems in industry is:

  • Up to 50% of total process heating energy 

 

Advantages of efficiency and renewable investments
