New UK Antarctic base uses CHP to manage fuel use

Exhaust gas heat exchangers from specialist UK manufacturer EJ Bowman are to help provide the ‘green’ power at the new British Antarctic Survey research station, the Halley VI station, currently under construction on the Brunt Ice Shelf, Antarctica.
 
The heat exchangers form a part of the CHP unit that will supply energy to the base, delivering heating, lighting, ventilation and power.
 
The station, the UK’s most isolated research facility, will house laboratories and living accommodation for BAS scientists. Even in the middle of summer, the average temperature is only -5°C, plunging to -50°C in winter.
 
Designed by Westac Power Ltd, the CHP unit makes use of waste heat to warm the buildings and melt snow to provide water.
 
The Bowman heat exchangers capture the waste heat from the exhaust and cooling systems, which would otherwise escape to atmosphere.
 
The heat exchangers can reclaim up to 60% of all lost heat from the engine and achieve total performance efficiencies of up to 92%, says Bowman.
 
With an estimated demand of 240 cubic metres of fuel per year to keep the station operational, reducing energy consumption and emissions was seen as critical in the design of the power system.
 
The heat exchangers help lower the cost of operation by reducing energy consumption which in turn results in fuel savings in terms of both consumption and fuel shipment costs.
