Our History

STEAM was established in 1987 as an engineering company for the purpose of operating in the Energy and Environmental sectors with reference to Geothermal Energy development. Its principal partners were coming from Enel and having many years of experience in geothermal field with particular reference to drilling, reservoir engineering and geological geophysical survey studies.
STEAM initially focused its business in providing consulting, operational and training services in the development assessment and evaluation of worldwide geothermal resources to the most important geothermal firms (ENEL Green Power, DAL, Geotermica Italiana).
Following to the addition of new partners with a great experience in consulting services and the tight collaboration with worldwide environmental consulting company (ERM Group), STEAM consolidated its competences in environmental services, collaborated to Institutional Strengthening Programs with International Organizations (World Bank, EBRD, Italian Ministry of Environment) and was involved in audits and restoration projects, also on UNEP environmental hot spots.

In the meantime, the Geothermal Division of STEAM carried out a reconnaissance study of the Italian Medium Enthalpy Geothermal Resources and cooperated with private financial investors to apply for Geothermal Research Permits in Italy.


The Company is now organized with a solid and competent permanent team and a wide, open and flexible group of very experienced geologists and engineers, who have successfully accomplished projects on almost every continent. Having provided services in the geothermal energy field to the most important international organizations (World Bank, EBRD, MISE), geothermal investors (Enel, KenGen), consulting firms (DAL, GI), services suppliers (Saipem) and technology provider (Toshiba, Ormat, Exergy) and following to the addition of new partners (including SINTECNICA) with outstanding experience in this field, STEAM decided to maintain its environmental business and to expand its focus to the international geothermal market. With this aim STEAM is nowadays carrying out an evaluation of the possible areas of intervention, starting from the geographical areas and Countries where the members of its team have experience, having worked in the past, as Latin America, North America, China, East Africa, Indonesia, Middle East...
