The TERA (Technoeconomic Environmental Risk Analysis) methodology, used for the European aviation industry under the leadership of Cranfield University, will provide a valuable insight to investigate the most promising systems in terms of multidisciplinary criteria and to estimate their competitiveness, so as to facilitate their route to commercial operation with benefits for the UK energy industry and for the long term needs of the community. TERA methods are being developed for power generation and the oil and gas industry in association with two major players in the energy field.
