Why develop a gas engine HP?

> Combination with ATES systems or waste heat source

> Demand for higher temperatures in commercial buildings

Central heating

Hot domestic water

> Increase ATES output on heating, or decrease ATES volume

> High ambitions for sustainability

Our approach

First: make base load energy demand sustainable by:

> Analyzing energy flows in production process

> Analyzing energy flows in utilities

Heating

Cooling

Hot domestic water

> Matching and/or buffering energy flows

> Saving energy costs and exploitation costs

What is “sustainable”

Analyzing and understanding client’s process

> Reliability

> Energy saving and exploitation costs during lifecycle

> Integrated (overarching) approach

Process is leading. Sustainability follows.

Project example: hospital

> GW installed in central boiler room> Produces heating and domestic water

instead of steamboiler> Produces cooling water instead of chiller

> Simultaneous production of heating and cooling> Baseload covered> Alternatives for peak load and back-up

> ROI < 3 years> PER > 3> Combined heating & cooling for € 0,016 / kWh !

( with gas price € 0,45/m3 )

Project example: datacenter

> ROI < 3 years> 183.000 kg CO2 reduction> > 50.000 m³ natural gas saved

Future

> Export in EU

> Propane as a natural coolant

> Focus on higher temperatures (60 – 80)

> Outdoor installation

> Trigeneration (Heating, Cooling, Electricity)
