Waste Heat Recovery

Generating electricity from the capture of wasted heat. 

Solving a 'heated' topic of wasted unused energy

24 hours a day, 7 days a week, all over the world, heat is constantly escaping from plant and property and is simply being lost as a waste of energy and a waste of money. 

Having the ability to instead capture and convert that wasted heat into ‘new’ electricity you haven’t had to buy from your energy supplier is obviously a very green technology that will reduce annual electricity bills and carbon footprints.

Using Organic Rankine Cycling (ORC) to recycle waste heat

Organic Rankine Cycling Technology (ORC) is not a new technology. A prototype was first developed and exhibited in 1961 by solar engineers Harry Zvi Tabor and Lucien Bronicki. It was named after Scottish Inventor William John Macquorn Rankine (1820-1872).

ORC can be used wherever there is surplus hot gas/liquid of sufficient volume-flow. Most industrial processes, factories, hospitals, laundries waste processing plants, incinerators etc., produce waste energy of this nature.


The Business Benefits of ORC

 Increased energy efficiency.

Energy is expensive. By harvesting the energy escaping to the atmosphere better value for money is achieved.

By capturing and re-using this energy going to waste it is reducing the amount of new energy having to be purchased in from the National Grid.

Residual heat re-use.

After extracting the necessary heat energy required for electricity generation, the residual heat can be used to provide for additional heating and hot water needs.

Environmentally friendlier.

ORC is a cleaner tech, not dependent on the weather and with zero emissions of its own, helps reduce one’s carbon footprint by reducing emissions already expended.


Traditional verses Advanced ORC installations

The challenges of traditional ORC installations

  • Traditionally, ORC are more suited to large industrial sites, with budgets to match.
  • The larger footprints needed may be prohibitive for many sites.
  • Traditional ORC requires temperatures in excess of 300°C and 30bar of pressure.
  • Efficiency averages of between 7-8%
  • Requires a central heat source not disparate.

The features and benefits of Advanced ORC.

  • Non-combustible, non-flammable organic working fluids are non-hazardous to human health.
  • Operates under relatively low temperature and pressure conditions.
  • A smaller footprint.
  • Easily installable and enabling cheaper and more convenient placement closer to the heat source.
  • Modular – Units varying in size from 10kW to 150kW can be installed on their own or combined together.
  • Remote Internet Monitoring Provides low cost maintenance and support
  • Configuration optimised – Each unit is optimised for specific client requirements, aligning to a specific heat source to maximise the electricity generated 

The Financial Advantages of ORC

An attractive Return on Investment

  • Low cost per kW for ORCogen ORC units.
  • Delivers a payback of 2-4 years depending on operating conditions.
  • 20-year lifespan

Increased Cash Flow

  • Advanced ORC delivers increased efficiencies of 9-15%, against a market average of 8-11%,
  • Maximise the kW output reduces the net electricity costs

Lower costs

Smaller, easier to install advanced ORC units reduces installation costs for new installations or retrofitting.
