           GTE granted EU Patent for on-wing turbine wash technology


Gas Turbine Efficiency plc ('GTE' or 'the Group'), a leading manufacturer of
advanced systems to clean, monitor and enhance the performance of aviation and
industrial turbines, is pleased to announce that it has been granted a European
Patent concerning its advanced on-wing aviation wash systems.

A patent application entitled 'Universal Manifold System for Washing an Aero Gas
Turbine' Patent was filed on 8 June 2005 and was awarded to GTE, effective 22
November 2007. The patent relates to key parts in the design of GTE's highly
environmentally-friendly aviation wash systems. These systems have been deployed
on a wide range of aircraft engine designs through GTE's exclusive aviation
partner, Pratt & Whitney, and have delivered validated reductions in carbon
emissions, fuel costs, engine downtime and longer parts life.

Key features of the systems include a universal manifold, automated positioning,
100% capture of effluent and treatment, allowing closed loop washing at the
gate. Using GTE's systems, major airlines have achieved fuel savings of up to
1%, turbine wash times of as low as 30 minutes per engine and carbon dioxide
reductions of 3.1 kilograms for every 1 kilogram of fuel saved.

Steven Zwolinski, Chief Executive Officer of GTE, commented: 'We are delighted
to be granted this European patent for our world-class aviation wash systems.
The patent strengthens GTE's intellectual property position in the design of
turbine wash systems, which set the benchmark for delivering highly
environmentally-friendly and value enhancing solutions for aircraft operators
worldwide.'
