State-of-the-art biomass boiler technology from Remeha has ensured that Stansted Airport’s new £50 million terminal extension is a low to zero carbon zone. And, says Stansted’s head of environment, the boiler has outperformed all expectations during its first winter of operation.

The 2000kW biomass heating boiler is one of the biggest in commercial use in the UK. Supplied by Remeha and manufactured by European company Gilles Austria, it is powered by woodchips.

The boiler is part of BAA’s commitment to reducing the environmental impacts of development and day-to-day operations. It makes the new airport extension, completed in 2008, a low to zero carbon building.

Indeed its performance has proved so efficient that is it now the primary boiler for the whole airport. Results indicate the biomass technology is set to help reduce predicted annual gas consumption at the airport by nearly 40%.

“To say we’re delighted with the performance of the new biomass boiler is an understatement,” says head of environment at Stansted Airport, Andy Jefferson.

“We set out to ensure the recent terminal extension would be carbon neutral but performance data so far indicates those savings go much further, with results between November 2008 and March 2009 alone showing that gas consumption at Stansted was around 60% of the predicted forecasts for this period, and over 30% lower than the same period for the previous year. And all this despite it being one of the coldest winters on record for over a decade.

“Whilst initiatives such as our asset replacement programme have contributed to these overall results, the introduction of biomass technology has by far been the largest contributor.

“We’re proud to maintain our leading position as the largest UK airport to hold ISO14001 accreditation for environmental management.”
