Energy transition poses the great challenge of bringing the global energy sector to zero-carbon by the second half of this century. The fight against climate change requires a concrete commitment to decarbonization, in all sectors, especially industry, transport and power generation. In this scenario, hydrogen is the key energy carrier for a sustainable energy transition, as it is capable of ensuring zero-emission energy generation. Ansaldo Energia is able to respond to the decarbonization challenge with products that perfectly fit future needs. We have in place more than 15 years' experience in hydrogen use to feed a gas turbine in power generation plants: thanks to our R&D efforts and our proven know-how, our hydrogen capability ranges from 25% to 70%, depending on turbine model. Our commitment is to reach 100% by 2030 or earlier across the whole product range.
