The A380's engines (The Rolls Royce Trent 900), are capable of operating with a mixed cynthetic fuel. During testing, the jet flew with a mix of standard jetfuel and a 40% mixture of a methane based liquified natural gas byproduct. It's also the first to use an increased pressure hydraulic system. The A380's system is pressurized at 5000psi insted of the standard 3000psi system for large jets.

1) "No fuel stops: The A380 Airbus can fly between 14,200 and 16,200 kilometres without refuelling, at a maximum cruising speed of 1,080 kilometres per hour. Environmentally friendly: The A380 Airbus will be quieter and cause less pollution than the Boeing 747, using 13% less fuel (less than three litres of fuel per passenger per 100 kilometres) and costing between 15 and 20% less per kilometre. Giant of the air: With its length of 73 metres, a wingspan of 79.80 metres, a height of 24.10 metres (as tall as a nine-storey building), a fuselage 7.10 metres in diameter, two decks, a weight of 560 tonnes and 22 wheels, it can carry between 555 and 800 passengers (compared with 416 for the biggest Boeing 747) or 150 tonnes of cargo... Innovative materials: The central section is made of carbon fibre (a world first), the cabin floor of composite materials and the upper part of the fuselage of "glare" a glass fibre and aluminium alloy."

Other advances for the A380 include an Autopilot Traffic Collision Avoidance System that offers additional protection when compared to conventional TCAS systems, and the Airbus-patented “Brake-to-Vacate” technology – which allows pilots to select an appropriate runway exit when landing and regulate the aircraft’s speed and deceleration accordingly." Source and further information: http://www.airbus.com/en/corporate/innovation/ "By incorporating the latest advances in structures and materials, the A380 offers a direct operating cost per passenger that is 15 per cent lower than the competing large airliner. Reliability and maintainability will be further increased through the use of new technologies such as an enhanced onboard central maintenance system and variable frequency generators (which simplify the large aircraft’s electrical generation network). New-generation engines, combined with an advanced wing and landing gear design, will make the A380 significantly quieter than today's largest airliner – enabling the very large aircraft to meet strict local regulations at airports around the world."
