EXERGY TECHNOLOGY APPLICATIONS

Geothermal

EXERGY develops, designs and manufactures the most efficient Organic Rankine Cycle binary power plants for geothermal sources lower than 200°C. It represents the most important market for EXERGY.

Based on Radial Outflow Turbine technology, EXERGY offers the following advantages:

Superior efficiency
Better exploitation of high enthalpy resources and suitable for low temperature (as low as 90°)
Very cost effective in multiple pressure plant
Less maintenance
Extreme flexibility for changing geothermal fluid conditions (flow, temperatures and constituents due to a higher number of stages)
Projects from 1 MW – 50 MW in size

Heat recovery from industrial processes and power stations

Heat recovery is an area ideally suited to the EXERGY engine, that gives better efficiency for lower temperatures applications and eliminates the requirement for water for treatment and make up. This solution is ideal for companies facing the increasing cost of energy supply and are looking for ways to improve their energy efficiency as well as reduce their impact on the environment. Main target clients are: cement plants, steel mills, glass factories. The main advantages are:

No water treatment plant or make up water
Automated operation
Competitive capital costs, leading to fast payback
High efficiency at a variety of operating temperatures and loads
Fast start up and shut down
Flexible placement, away from the heat source if required
In industrial process heat recovery, it reduces plant energy consumption and carbon footprint

Biomass

In small biomass plants characterized by reduced capacity and high temperatures, the ORC is an ideal choice due to his high efficiency, availability and ability to follow load dependent on fuel supply. In addition, the elimination of the steam turbine for traditional biomass solutions brings with a number of maintenance and operational benefits. The main advantages are:

High power and efficiency to capital cost ratio
High reliability thanks to proven technology
Flexibility in biomass feed quality
Small modular, lightweight plants for easy installation
Few civil works required
The absence of a steam turbine simplifies operations and reduces maintenance
No water consumption High reliability thanks to proven technology

Concentrated Solar Power (CSP)

The Organic Rankine Cycle (ORC) is suitable for converting the thermal energy collected by solar panels into electricity through a thermodynamic cycle with a high level of efficiency. Using ORC in a solar thermal application is a cost efficient solution for clients. This solution has many advantages including:

Higher flexibility than traditional steam cycles
Ability to produce electricity from a lower temperature heat source
Possibility to build a small installation (<1MWe) with the option to scale up in the future
Lower set up costs for the ORC and solar panels
Simple operation and maintenance, as with all ORC units
Remote control of the ORC unit
A straight forward authorization and permission process
