Ansaldo Green Tech is a subsidiary fully owned by
Ansaldo Energia, established in June 2021 to address
the sensitive moment of the energy transition through
an important business diversification. A spin-off
dedicated to defining new technologies and products
for the energy transition, guaranteeing an adequate
approach to the market, backed by the expertise and
tradition of Ansaldo Energia, with its nearly 170 years
of experience.

“At a time when a strong growth in energy produced

definitely becomes crucial”, says Daniela Gentile,
CEO of Ansaldo Green Tech. “This is why the
agreement reached with Energy Dome is a source of
great satisfaction and a really important step for the
