The SteamDry project aims to develop and pilot innovative superheated steam drying (SSD) technologies for web-like materials such as paper, board, tissue, and nonwovens. The primary goal is to significantly reduce the CO2 footprint of the paper and pulp industry by enhancing energy efficiency and sustainability.
Context and Motivation
The paper and pulp industry is one of the most energy-intensive sectors, with significant CO2 emissions resulting from conventional drying processes. Traditional drying methods, such as contact cylinder and convective hot air drying, have limited energy efficiency and inevitably produce CO2 emissions. The need for more sustainable and energy-efficient drying technologies is critical to address the environmental challenges posed by this industry. The SteamDry project tackles these challenges by developing SSD technology, which utilises the superior heat transfer properties of superheated steam. This closed-loop system electrifies the drying process and maintains temperatures above the vaporisation point, resulting in lower net energy consumption and the use of surplus steam for other purposes within the facility.
SteamDry Project Objectives
The SteamDry project aims to revolutionise drying in the pulp and paper industry by developing superheated steam drying (SSD) technology. Its objectives include reducing energy use by over 60%, eliminating CO2 emissions, piloting SSD for web-like materials, and deploying AI-supported control systems for safe, efficient, and scalable industrial adoption
Pathway to Impact
SteamDry follows a structured path from research to commercialisation, involving seven research institutions, five industry stakeholders, and two technology providers. The project’s comprehensive approach starts with R&D, proceeds through pilot trials, and prepares for commercial scale-up. Collaboration is key, with partners ensuring successful SSD development and implementation. Pilot and lab results benchmark SSD technology against existing best practices, with advanced controls optimising performance and safety.
Expected Impacts
SSD technology’s use of superheated steam dramatically cuts energy use, repurposes surplus steam, and sustains closed-loop efficiency. This supports the EU Green Deal and climate goals by potentially saving 127 TWh/year in Europe and up to 870 TWh globally, translating to billions in cost savings and substantial CO2 emission reductions. Faster drying enhances product quality while compact design and system integration improve efficiency. Digital control and innovations in steam-air separation and purification further drive sustainable, energy-efficient manufacturing.
