Compressed air combined heat and power plants (Direct Drive Compressors DDCs):
Compressed air and Heat
generated highly efficiently
with hydrogen, natural gas or biogas
Save money and a lot of CO2 at the same time!
Would you also like to save a lot of money and CO2 when generating compressed air (up to CO2 neutrality)? Then generate compressed air from H2, natural or biogas instead of electricity with our DDC - and the heat is free!
Amortization possible in less than 2 years!
Functionality:
As an example: a compact, turbocharged natural gas engine for maximum efficiency and power output (e.g. 2G Energy 406 Erdgas, 248 kWmech) directly drives a screw compressor (e.g. Aerzener VMX). This then generates 40 m³/min of compressed air at 8 bar(g).
This would so far require an electric compressor with approx. 246kW of electrical power consumption, but instead we only natural gas or other corresponding gases, at much lower costs.
In addition to the compressed air, this machine generates useful waste heat from engine cooling, exhaust gas cooling, compressed air cooling, which additionally reduces your conventional gas heated boiler costs a lot.
By the way: the natural gas engine can already be "H2-ready" if desired!
Where does a DDC fit best?
1. Production from two shifts per day
Do you have a high compressed air and heat demand, at least for two shifts per day ?
2. Low gas price
Are you already a major consumer of natural gas?
3. High electricity price
The higher your electricity to gas price ratio,
the more interesting a DDC is for you.
4. Extension / renewal planned?
Replace an old compressor,
or add a DDC.
5. ISO 50001 planted?
Do you want to do something for energy efficiency
and environment ?
Save significant money
in compressed air generation
Cost savings of up to more than €250,000 per year are possible, with installation costs of the DDC system of around €400,000, by replacing electricity consumption with natural gas.
Highly efficient DHKW technology
A gas engine compressor for up to 26 m3/min compressed air at 8 bar(g) in the size of a 20-foot container, which drives a compressed air screw with a highly efficient gas engine (> 41% efficiency) - and you can also use its waste heat for the Heating (90°/65°) is available.
Increases operational safety
Supplement your existing compressed air station with a DDC for the compressed air base load.
