A French consortium, composed of Lhyfe and TSE, is to create a green energy hub and reindustrialise the Poitou Foundries site, with support from the Nouvelle-Aquitaine Region (France)

Nantes (France), 30 August 2023 - 5.45 pm CEST– Lhyfe (EURONEXT: LHYFE), a producer and supplier of green and renewable hydrogen, and TSE, an independent French solar energy producer, announced that they are to build the bases of a veritable industrial park centred around green energy and the circular economy, on the site of the former Poitou foundry (Fonderies du Poitou), with the installation of a solar park and a green and renewable hydrogen production unit.


A site take-over co-developed with exceptional support from the Nouvelle-Aquitaine region

A year after the site's closure, the Commercial Court of Paris just rendered its decision on the take-over of the land and real estate assets of the Fonderies du Poitou sites. These include the Ingrandes Foundry (a 43-hectare site with 40,000 sq. metres of buildings) and the Oyré Technical Landfill Centre (a 35-hectare site).

The Ingrandes Foundry site will be taken over by the consortium, formed of a joint venture between Lhyfe and TSE. As for the Technical Landfill Centre, it is being fully taken over by TSE, which will devote the land entirely to the production of solar energy with a 45 GWh plant.

Lhyfe and TSE have been preparing the site take-over for over a year and a half, accompanied and supported by the Nouvelle-Aquitaine Region, the urban community of Grand Châtellerault, the Prefecture of Vienne and the Sub-Prefecture of Châtellerault, with a view to building a common project that goes far beyond the “simple” production of green hydrogen or green electricity.


A reindustrialisation project centred around green energy

The joint Lhyfe and TSE project for the Ingrandes Foundry site is particularly ambitious. It involves firstly dismantling the existing infrastructure and cleaning up the site to make it compatible with the industrialisation process, thanks to the Green Fund, and then building the bases of a truly ecological industrial park where companies will work in synergy”, explained Ghislain Robert, Sales Director for France at Lhyfe.

After nearly two years' work, in consultation with and with the support of the regional authorities, TSE and Lhyfe are proud to have formed an innovative consortium that is leading this project for the revitalisation of the historic Poitou Foundries site. It is a green and virtuous reindustrialisation project, creating jobs that will accelerate energy transition and regional economic development”, said Alban Casimir, Deputy Managing Director in charge of Industry Convergence at TSE.

The photovoltaic power facilities that TSE plans to install at the landfill centre site and at the Ingrandes Foundry site could supply electricity to the latter, allowing Lhyfe to produce green and renewable hydrogen. The power produced will be equivalent to half that consumed by the city of Poitiers.


A virtuous project to revitalise the local economy

Several companies have already expressed their interest in joining the Ingrandes site, in synergy with Lhyfe and TSE, such as an industrial logistics company which plans to create a 20,000 sq. metre logistics centre at the site, as well as e-fuel producing companies (e-methanol and rDME).

Eventually this green energy hub should, thanks to the contribution of all involved companies, help create 250 to 300 jobs, with investments expected to amount to several hundreds of millions of euros.

For the Region, this is a landmark regeneration project for a major industrial site in Nouvelle Aquitaine. Focusing on green energy and the circular economy, this project led by the Lhyfe and TSE consortium will create hundreds of qualified and non-relocatable jobs. It is fully in keeping with our NeoTerra strategy and our desire to become France's No.1 eco-responsible region. It is a boost for the Châtellerault employment area, which was heavily impacted by the successive crises of these last few years”, stressed Alain Rousset, President of Nouvelle-Aquitaine Region.

“Our community welcomes this news with great enthusiasm and pride. Just a year after the wind up of Fonderies du Poitou, we are going to write it a new chapter, thanks to the combined efforts of public authorities. The project led by the consortium is in line with our desire to make Grand Châtellerault an area for green industry and, most importantly, with the objectives of our Territorial Climate, Air and Energy Plan. Providing more than 250 jobs, this, here, is a major factor of attractiveness for the community”, said Jean-Pierre Abelin, Mayor of Châtellerault and President of the Grand Châtellerault urban community.

The Préfecture de la Vienne also confirmed this project as a part of one of the pillars of the France 2030 investment plan (funding could be mobilised in the long term), like the Council of Nouvelle-Aquitaine Region which must, within the framework of Neoterra, receive financial support.

In 2021, Lhyfe inaugurated the first industrial-scale green hydrogen production plant in the world to be interconnected with a wind farm. In 2022, Lhyfe inaugurated the first offshore green hydrogen production pilot platform in the world.
Lhyfe is represented in 11 European countries and had 149 staff at the end of 2022. The company is listed on the Euronext market in Paris (ISIN: FR0014009YQ1 – LHYFE).

About TSE
TSE is an independent French solar energy producer which is active across the entire value chain. It has 17 solar power plants in operation, equivalent to the power consumption of 130,000 inhabitants. In September 2021, TSE inaugurated the second biggest solar power plant in France, in Marville, in the Meuse department, with an installed capacity of 150 MW and a surface area of almost 150 hectares.
With a totally innovative agricultural shade solution, TSE is also a leader in agrivoltaics and in September 2022 inaugurated its first farm canopy, a world innovation, in Amance, Haute-Saône, on a field of arable crops.
In April 2023, TSE raised 130 million euros in capital to consolidate its development.
In May 2023, TSE announced its participation in the Holosolis consortium which plans to build a photovoltaic gigafactory in Sarreguemines. With a production capacity of 5 GW a year, the plant, once fully up and running, will produce 10 million photovoltaic panels, equivalent to the energy needs of one million homes.
