ALSENAM, the result of the merger of two ALCEN subsidiaries, ASTF and SERCS, manufactures technical welded-sheet metal parts for high-tech sectors (aeronautics, space, energy, etc.). Designed to withstand high mechanical or thermal stresses, these parts meet the strictest dimensional and quality criteria.

The ALSENAM teams work out of two design offices and three small and medium-run production sites, including a "best cost" plant in Tunisia, which enables them to participate throughout the projects entrusted to them, from co-development at objective price through to assessment and maintenance.

ALSOLEN develops medium-power Fresnel reflector solar thermal power plants (up to 100 MWth or 20 MWe) known by the same name, ALSOLEN. These use oil as the heat transfer fluid and have a direct rock-bed thermocline thermal storage system. The heat transfer fluid reaches a temperature of 300 °C and transfers its thermal energy to applications that, depending on the needs of users, can be combined between: electricity, industrial heat, cold and desalination of seawater. ALSOLEN solar power plants are more specifically designed for operation in an isolated or semi-isolated grid and require an operating level that is not very restrictive.

The originality of ALSOLEN solar thermal power plants lies in part in their design, which incorporates as much manufacturing as possible on the installation site (thanks to the use of a mobile factory), high performance, low, easy maintenance, and a long service life. Integrated thermal storage is used to obtain operational autonomy appropriate to the needs of users, even several hours after sunset.

The technology used for each application corresponds to the design strategy of ALSOLEN power plants. The electricity generation applications use an Organic Rankine Cycle (ORC), the cold is generated by an absorption chiller enabling negative temperatures to be reached and fresh water by multi-effect distillation.

All of the ALSOLEN power plant development work has been done in conjunction with CEA LITEN and ALCEN subsidiaries.

A high-power thermal solar power plant (50 MWe and above) called ALSOLEN SUP is at an advanced stage of development. The ALSOLEN SUP technology will directly generate steam superheated to 450 °C and will have a three-stage thermal storage capacity. It will present specific clean innovations to the market and benefit from ALSOLEN innovations.

With over 20 years of existence and experience, ITHPP has become the French leader in high-pulsed power and high-power microwave technologies. 

Driven by customer specifications, IHTPP designs and manufactures highly adapted and innovative systems linking the technologies to scientific research, civil and military applications. 

High Pulsed Power technologies allow the amplification of electrical power delivery  over a shorter burst duration. Since energy is the product of power over time, by maintaining a constant flow of energy and reducing the duration of the pulse it is possible to achieve powers in excess of a hundred Gigawatts.

High Powered Microwaves are very highly charged electromagnetic pulsations capable of disturbing and even destroying electronic components used in increasingly complex systems. The interest in these high powered microwaves are due to the vast array of usages, varying from more classic usages (Radar types) to more advanced technologies, such as those used  in Electronic Warfare.
