Clairefontaine selects Dall Energy’s gasification tech for French fuel switch project

Clairefontaine selects Dall Energy’s gasification tech for French fuel switch project
Strategically located 90 km from Strasbourg, along the Meurthe river at the crossroads between France, Germany, Switzerland, and Benelux, the Papeteries de Clairefontaine Etival-Clairefontaine paper mill is equipped with two paper machines 3.40m wide and delivers 170 000 tonnes per annum of uncoated printing and writing paper to its customers. The paper is exclusively top-of-the-range, for office automation, graphic printing, and the manufacture of stationery articles (photo courtesy Clairefontaine).

Danish biomass gasification and pyrolysis technology company, Dall Energy ApS, has announced that it has closed on a DKK multi-million deal with bespoke French paper group, Clairefontaine for the supply of its proprietary biomass gasification technology for a boiler replacement project at a paper mill in France.

Founded in 1858, Papeteries de Clairefontaine is a French family-held bespoke papermaker specializing in school, fine arts, handicrafts, and office stationery.

Now part of the Exacompta-Clairefontaine group that comprises some fifty companies and employs over 3 200 people in Europe and Africa, including 580 at Papeteries de Clairefontaine paper mill in Etival-Clairefontaine, France.

All the papers used by the group are manufactured at Clairefontaine’s four production sites – Etival-Clairefontaine, Everbal, and Mandeure in France, and Schut, the Netherlands.

A high-end solution for a high-end company

In France, companies are looking to transition all energy consumption in manufacturing away from fossil gas. This means that large companies like Clairefontaine need technology to help them. Fast and efficient.

Ann Bouisset, Sales Manager at Dall Energy, here seen at the 2022 edition of Bio360 Expo in Nantes, France.

The company is recognized in its home country as a high-end paper product manufacturer – and as a pioneering company when it comes to sustainable operations through its focus on the preservation of forests and watercourses.

Clairefontaine has embarked on a project to replace an aging fossil gas-fired boiler unit at its Etival-Clairefontaine production site with a biomass-fired boiler unit. This new unit will be linked to an existing cogeneration unit to cover the high energy requirements of paper production at the paper mill.

To this end, Dall Energy’s high-end biomass gasification technology is seen as a perfect fit for the high-end Clairefontaine brand – both in terms of the financial business case and in terms of its quest for an even greener future.

The choice of the Dall Energy gasification and combustion system was made primarily due to two reasons. Firstly – the Dall Energy gasification technology permits the use of a very large range of fuels and means a better business case, and secondly also very importantly: the flexibility of operation as the Dall technology allows for quite fast changes in load, between 10 percent and 100 percent, which is less possible with a grate-fired plant, a spokesperson for Clairefontaine said.

Biomass gasification with CCU

Using around 60 000 tonnes per annum of residual biomass from forestry operations, the 22 MW biomass steam boiler plant will reduce the plant’s annual gas consumption by 45 percent and, with a production of 25 tonnes of steam per hour, will provide 50 percent of the paper mill’s steam requirements.

Furthermore, the plant will include carbon capture and utilization (CCU) capabilities whereby carbon dioxide (CO2) from the flue gas will be captured and used in the manufacturing process.

According to Clairefontaine, the investment for the boiler replacement project amounts to around EUR 37 million and will be partly financed by the Government through the “France Relance” plan administrated by the Agency for Environment and Energy Management (ADEME) and Energy Savings Certificates.

International breakthrough

For Dall Energy, the agreement represents the largest single contract for the company to date and its second project in France.

We are beyond satisfied to have made an agreement with such an iconic French company. This proves that our patented, scalable, and unique gasification technology is able to provide something that no one else in our industry is able to – yet which many, especially, manufacturing companies need in their quest for sustainable energy sources. Not least in France, where we expect more deals in the coming years, as its companies seek to secure a sustainable green transition, said Ann Bouisset, Sales Manager at Dall Energy.
