The Energy Technologies Institute (ETI) was a public-private partnership between global energy and engineering companies and the UK Government that was established in the United Kingdom in 2007. The government set up the ETI following an announcement in the 2006 budget speech. The purpose of the ETI is to “accelerate the development, demonstration and eventual commercial deployment of a focused portfolio of energy technologies, which will increase energy efficiency, reduce greenhouse gas emissions and help achieve energy and climate change goals”. The institute works with a range of academic and commercial bodies.
