 The Impress Project is a large five-year program with 40 partners coordinated by the European Space Agency. The objective of the project was to investigate the processes of intermetallics, and in particular the titanium aluminides for gas turbine engines and a nickel aluminium for catalytic applications. With a 30cm blade from a turbine engine, when it's produced of the nickel super alloy, it weighs 2.5kg. When it's produced in titanium aluminide in the project, it's only 1.2kg, so it's more than a 50% saving in weight. And this is the 40cm blade produced in the program, and it only weighs a little bit more than the nickel blade in 30cm. So there's a big saving in fuel and CO2 emissions by using this. And this is the nickel aluminium alloy, and when this sample is activated, it has a surface area larger than an Olympic swimming pool, and it's 10 times more active than the standard nickel alloy. The titanium aluminides have some very attractive properties up to about 800 degrees, but they've been very difficult to process because they're very reactive and they have low deatility at room temperature. Within the project we've solved those problems, and we've now developed the technology for casting these, and also for recycling them afterwards. And already that's a manufacturing route which has been exploited in the UK and Germany and also in Belgium. The potential for the technology is maybe 2 billion euros over the next 20 years. For the nickel catalyst which has been developed, it's 10 times more active than the current catalyst, and it has some potential for use in alkaline fuel cells, and there's already scale-up plans up to 100 kilos where we're exploiting the technology.
