Following a long tradition of continuous technological updating, in February 2003 Ceresa Energy & Facility launched a medium-term research program on the applications of hydrogen systems (fuel cells) for building use. In collaboration with private companies, organizations and research institutes, the program will entail the study and testing of products and techniques expected to be on the market as soon as 2010. Ceresa is thus preparing for what will become the energy revolution of the 21st century, involving not just new ways of producing energy, but a major transformation in all areas of the sector – design, production, distribution, management, and assistance. This challenge may be the biggest ever faced by the company – the challenge of producing energy with "zero environmental impact".
