Fuel Cells Rolls Royce

Fuel cells

Product details
The Rolls-Royce fuel cell system is lower cost; more efficient; more easily distributed; more durable and maintainable than its nearest rival.

Rolls-Royce has experience in the system integration of several different types of fuel cells and believes the Solid-Oxide Fuel Cell is the best for stationary power generation applications while retaining the capability of being developed subsequently for various transportation, military and marine applications.

The fuel cell is produced by screen printing on low cost ceramic type materials using proven production processes and minimal exotic materials.

Low cost
The system uses commercial-grade materials, has few components and is low in weight.

Nearly double the simple-cycle efficiency of existing power generation technologies.

Size and weight suitable for distributed generation with potential for power densities equivalent to gas turbine systems.

Negligible air emissions, minimal noise profile and can be entirely recycled at the end of its useful life.

Unique, modular design enables field change-out without interruption of supply and enhanced support through state-of-the-art diagnostic and prognostic systems.

System contains less than ten seconds of fuel supply at any time.

Low parts count and the elimination of low durability components gives a realistic design target of 40,000 hours operation on a mature product and a 20-year 160,000 hour overall plantlife potential.

Fuel flexibility
System can be configured to use existing hydrocarbon-based fuels, i.e. natural gas and liquid fuels, and alternative fuels such as coal gas and bio-mass.

Suitable for connection to local distribution networks and in small, secure urban areas.

Spey Rolls Royce


Product details
A versatile engine powering both military and civil aircraft types.

Thrust range up to 11,995lbf
Over 50 million flying hours accumulated
The latest of the Spey family is the Spey 807, a two shaft turbofan with a four-stage low pressure (LP) and 12-stage high pressure (HP) compressor driven by a two-stage LP and two-stage HP turbine respectively. The combustor is of cannular design with 10 liners, as all other Spey variants.

This engine first entered service more than 30 years ago and is used by military and civil customers around the world. The military Spey was developed to meet the needs of high performance aircraft in both subsonic and, with reheat, supersonic operations.

The Spey 807 for the single-engined AMX strike aircraft is in service in Italy and Brazil. Other Spey variants such as the Spey 250 power the BAE SYSTEMS Nimrod MR2patrol aircraft. In addition, the Spey powers the military versions of Gulfstream GII and GIII aircraft in service in VIP transport and reconnaissance roles with a number of armed forces around the world.

Besides military power, the Spey also provides power for civil applications of the Gulfstream GII and GIII executive aircraft, although the civil version is no longer in production. Other aircraft powered by the Spey include the BAC 1-11 and Fokker F28. The Spey entered service in 1968 and 2,768 civil and military engines were built, achieving over 50 million hours in service to date.
