The Trent 1000 engine, being developed to power the new Boeing 787 airliner, will be significantly more fuel efficient than previous Trent engines. This improved performance has been achieved through a number of advances in component and materials technology.
Rolls-Royce has developed a range of Bergen gas-fuelled reciprocating engines, which are well proven in land–based power generation markets, for use in the marine market. The Bergen K-type has already been sold to power new ferries operating in Norwegian waters. Emissions from engines running on natural gas contain typically 80 per cent less nitrous oxide and 20 per cent less carbon dioxide than emissions from traditional diesel engines of the same power output.
The Advisory Council for Aeronautics Research in Europe (ACARE) has set a range of challenging environmental improvement goals to be achieved by 2020. The Environmentally Friendly Engine (EFE) is the latest demonstrator programme to be launched by Rolls-Royce to enable us to meet these targets. The technology and improved efficiencies that EFE is planned to deliver will lead to reduced fuel consumption, while lowering emissions and engine noise.
The Group is developing megawatt-scale solid oxide fuel cell systems that have the potential to be clean, quiet, cost effective and highly fuel efficient. The technology yields significant reductions in carbon dioxide emissions relative to existing fossil fuel power generation technology and negligible nitrous oxide emissions.
