CONTINUOUS INNOVATIONH2, the new symbol of French industry. This new production unit, which will be the factory model deployed throughout the world, reflects this challenge: to design for the lowest possible impact.
A vertical plant unique in the world
This new production unit, still at our historic site in Bournezeau (85), marks an important step in the company’s development.
This plant, the only one of its kind in the world, is a concrete example of our industrial vision: cutting-edge technologies, advanced R&D and human collaboration to offer solutions to environmental challenges.
We believe in the virtues of industry to meet today’s challenges.
This new factory model will enable us to move from an industry that has been subjected to harsh environmental conditions, to an industry that is at the cutting edge of technology and at the service of environmental issues.
By multiplying our production capacity by 5, from 50,000 to 250,000 tonnes, H2 is helping to accelerate our development and enabling us to address the growing demand for our low-carbon cement without clinker.

H2, a technological and ecological feat
This new H2 plant is the fruit of a multitude of challenges: inventing a large-scale production process, combining industrial performance with minimum impact, and combining industrial production capacity with a small footprint.
The choice of a vertical production model enables us to limit our footprint and meet the Zero Net Artificialization (ZAN) targets set by the public authorities. This small footprint also makes it easier to locate in future development zones, with limited land requirements.
The vertical model also makes it possible to use gravity to optimize the production process. It is simpler and less energy-consuming to transport powdered materials by gravity than by conveyors or belts: less waste, less dust, less energy…
Hoffmann Green has also designed an intelligent, fully connected production process. The plant can be controlled by a global intelligent program. A man/machine/digital alliance that optimizes every stage and guarantees high quality standards.
Finally, the plant is over 50% self-sufficient in energy, thanks to the installation of 12 solar trackers.
A civil engineering tour de force
H2 is first and foremost a major innovation in terms of design and production.
Made entirely from Hoffmann Green concrete, it is yet another example of the performance of these new cements.
Designed by Ibau Hamburg and built by Eiffage Génie Civil teams in 1.80 m smooth formwork, H2 is a real feat of engineering.
The first part, up to 20 metres, was completed before 24 petals weighing 15 tonnes each were laid, prefabricated on site with concrete made from H-UKR 0% clinker cement, to form the plant’s inverted cone.
A fine demonstration of the quality of Hoffmann Green’s technologies, which successfully passed all CSTB pull-out tests for lifting elements.
The second part of the lift, from 20 to 70 meters, was carried out continuously over 22 consecutive days, 24 hours a day.
