High Gain Antenna Gimbal (HGAG) for the rover Perseverance of the Mars 2020 mission
We are part of an international consortium (Sener, General Electric and Bonatti) for the construction, maintenance and servicing work of two hydrogen-ready combined cycle power plants in Heilbronn and Altbach/Deizisau, Germany. This is a major energy transition project that will existing coal power plant sites into natural gas and, from the 2030s, green hydrogen plants.
The plants will be built on land adjacent to these coal plants and will share with them certain services such as the cooling tower, the workshop and warehouse or the control room.
, with an initial capacity to burn 20 % hydrogen (H2) and they will be technologically prepared for an expansion of up to 100 %.
The plants are both located on the banks of a navigable river, along which heavy equipment is transported to the plants.
Together with Bonatti, Sener is responsible for the complete detailed engineering, the supply of the BoP (balance of plant) and the complete construction of the power plant buildings and its chimney with its foundation.
A combined cycle gas turbine power plant (CCGT) with an electrical output of about 680 MW and a thermal output of up to 180 MW for heat extraction is planned for construction at the Altbach/Deizisau site.
After commissioning of the combined cycle power plant, scheduled for 2026, the coal-fired boilers, the associated flue gas cleaning system and the coal-fired auxiliary steam generators will be decommissioned.
With a maximum electrical output of 710 MW and around 190 MW of district heating capacity, the Heilbronn combined cycle gas turbine plant is being built to replace the currently coal-fired one and reduce carbon emissions by more than 50%.
To secure the supply of district heating, a heat storage facility with a capacity of 600 megawatt-hours and a hot water boiler system with a district heating capacity of approximately 170 MW are simultaneously being built.
During the conversion, part of the district heating grid will also be modernized in an energy-efficient manner by switching from a steam to a hot water network. The district heating grids supply around 300 industrial and commercial customers in Heilbronn and Neckarsulm, alongside around 150 residential buildings. The plant is expected to start operation by the end of 2026.
This way, the Heilbronn power plant will replace existing coal-fired plants with more efficient natural gas fired plants while enabling future fuel mix combustion of up to 20% by volume of hydrogen.
