A focus for energy technology


Michael Green, UCG Engineering Ltd.

MGreenDr Green is Managing Director of UCG Engineering Ltd, a UK engineering company, formed in 2004, to provide specialist technical and management services in the field of underground coal gasification.

He has a degree in Chemical Engineering, and a PhD and DIC from Imperial College, London for work on heat and mass transfer in boundary layers.  His early career was spent with Grumman Aerospace, New York working on space and missile programs, followed by a 26-year career in British Gas R&D, which covered gas utilisation, gasification and processing, general energy research, his final position as Technical Controller, Chemical Sciences, and two board positions in BG overseas companies in Spain.

On leaving BG, he became Director of the European trial of underground coal gasification in Spain (1996-1999) and later chief advisor to the UK Government initiative for UCG (1999-2004). He co-founded the UCG Partnership, later the UCG Association, to organise conferences and training courses and networking opportunities for UCG interests across the world. 

He formed UCG Engineering Ltd, which rapidly became a focus for UCG consultancy expertise, and worked in Australia, Eastern Europe and North America, providing feasibility, economic studies and pilot and field trial experience. He became the Board Director for Technology of the Australian ASX listed company, Clean Global Energy Ltd, to develop commercial UCG projects. Most notable was a study and agreements to supply syngas to an AES power station in Oklahoma and a partnership with Essar Energy, India to bid for UCG blocks. EU-supported UCG projects have included the €3.5M HUGE (2007-2010) and its €2.2M successor HUGE2 where he was Chairman of the Steering Committee, the €3.0m Bulgarian-led project to investigate CO2 storage in deep coal seams, and another, entirely, commercial UCG project, in Hungary.  He is recently being involved in the latest UK work on UCG in offshore coal deposits and is participating in future UCG opportunities in Argentina, Mongolia, and India.

He has authored many papers on UCG and energy topics and has over 40 years experience in energy related engineering research.  Hobbies include piano, spanish, golf and swimming.
