USC and Steamdry push Parametric LCA forward with new open access article

Parametric Life Cycle Assessment (Pa‑LCA) is becoming a key tool for designing the low‑carbon, resource‑efficient technologies we need for the green and digital transition. But until now, there has been no clear, shared roadmap on how to actually do Pa‑LCA in a robust, comparable way.

Researchers from the Universidade de Santiago de Compostela (USC) and their co‑authors have just published a new open‑access review article, “Advancing parametric life cycle assessment (Pa‑LCA): A systematic review and methodological roadmap for enhanced sustainability assessments.” This work looks at 95 Pa‑LCA studies from the last decade and distils them into a practical framework that helps researchers and practitioners design better parametric LCAs, from choosing parameters and KPIs to handling sensitivity and uncertainty.

For Steamdry, USC is a key partner leading the methodological and assessment work. Their role in the project is to develop and apply advanced LCA and Pa‑LCA methods, define key performance indicators, and make sure that the technologies developed in Steamdry are evaluated with the best available science. This new paper is a tangible example of USC’s contribution to Steamdry: it provides the scientific backbone we will use to build dynamic, transparent, and decision‑ready sustainability assessments throughout the project.

CHECK THE AGENDA

This joint Sustainable Energy Day by SteamDry and METAWAVE is organised in the framework of EU Sustainable Energy Week (EUSEW) 2026, the main annual event of the European Union dedicated to renewables and energy efficiency. EUSEW provides a platform to present innovative projects, exchange best practices and build partnerships that support the EU’s energy and climate goals, including higher energy‑efficiency targets, accelerated renewables deployment and climate‑neutrality by 2050.

By focusing on the electrification of industrial heat in sectors such as paper and board, ceramics, asphalt and aluminium, the event contributes directly to these objectives. Electrified process‑heat solutions like superheated steam drying and microwave‑based high‑temperature processes can significantly reduce fossil fuel use, lower greenhouse‑gas emissions and improve energy efficiency in some of Europe’s most energy‑intensive value chains. At the same time, they help implement key EU strategies such as the Green DealREPowerEU and the Industrial Green Deal, which all call for faster decarbonisation of industry while preserving competitiveness and quality jobs.

The session is designed not only to showcase technical progress, but also to inform policy. Through a combination of data‑driven presentations, project pitches and an interactive policy panel with representatives from EU‑level initiatives, industry and the European Parliament, the event will identify barriers and enablers for scaling up electrified heat. The resulting messages aim to support EU and national decision‑makers in designing regulations, funding instruments and industrial strategies that accelerate the transition of energy‑intensive industries in line with Europe’s climate and energy targets.

Steamdry at the 15th IEA Heat Pump Conference

Steamdry was pleased to participate in the 15th IEA Heat Pump Conference, where our partner AIT Austrian Institute of Technology presented a joint work on advanced heat recovery and drying technologies.

The presentation, titled “Heat recovery with steam compressor: Dynamic model of a superheated steam drying system to evaluate efficient system operation,” was delivered by Michael Pölzl (AIT) on Friday, May 29 in the Festsaal. It was part of the session “HTH11 + AIP2 Techno-Economic & Environmental Assessment of High Temperature Heat Pumps and Adaptation of Industrial Processes.”

This contribution, developed by AIT in collaboration with Piller Blowers & Compressors and Wageningen University & Research, focuses on superheated steam drying (SSD) as an innovative alternative to conventional drying processes in the pulp and paper industry.

SSD offers strong potential for improving energy efficiency, reducing emissions, and enhancing product quality. A key element of the system is the use of a steam compressor, which recovers latent heat from excess steam and upgrades it to the required temperature and pressure levels for reuse within the drying process.

To better understand and optimize this complex system, a dynamic model has been developed to simulate the transient behavior of the dryer, steam compressor, and auxiliary components such as heat exchangers and electrical heating. This model makes it possible to evaluate how different operating conditions—such as temperature levels and the presence of air in the steam cycle—affect overall system performance and efficiency.

The results demonstrate how such modeling tools can support the design and operation of superheated steam drying systems, enabling more efficient and reliable integration into industrial processes.

Through its partners, SteamDry is proud to contribute to the development of next-generation drying technologies and to support the transition toward more energy-efficient industrial solutions.

The presentation provided an opportunity to share the project’s latest developments with researchers, industry representatives, and other stakeholders working to advance sustainable and energy-efficient industrial processes.

About the event

The IEA Heat Pump Conference is one of the leading international events on heat pump technologies, bringing together industry, research, and policy to advance energy efficiency and decarbonization in heating and industrial processes.

Introducing the SteamDry Pilot Plant Infographic

When we talk about decarbonising drying, it can be hard to picture what the future actually looks like on a real machine. That’s exactly why we created our new SteamDry Pilot Plant infographic.

The infographic walks you through how we’ve rebuilt the VTT SAMPO pilot machine into a fully fledged Superheated Steam Drying (SSD) line. It shows the complete journey: from how the wet web enters the first hood, to how closed-loop superheated steam dries the sheet, to how waste heat can be recovered and reused in the mill.

At a glance, you can see the key technical parameters:

  • Speed range from low trial speeds up to near-industrial levels
  • Web width suitable for realistic scale-up
  • A long dryer section with two SSD hoods in series
  • High-temperature steam and installed power enabling efficient drying
  • A very wide basis-weight window, from light grades to heavy structures

In parallel, the infographic highlights why SSD is such a strong candidate for low-carbon drying. By circulating and reheating steam in a closed loop, the system offers the potential for significant energy savings and a much higher drying rate than conventional hot-air systems. Because the exhaust is steam, its latent heat can be captured and reused, supporting more circular heat management at mill level.

You’ll also find a clear, step-by-step process flow: how the sheet enters, how the steam is superheated, how it circulates through the hoods, and how an optional IR section can be used for final moisture adjustment. For users of pilot facilities, this gives a concrete picture of what kind of trials are possible and how flexible the line really is.

The infographic also touches on the technical challenges that our team is addressing, such as sealingsteam purity, and thermal durability of fabrics and materials at high temperature. These are exactly the issues that need to be solved to pave the way for full-scale industrial implementations.

Finally, the infographic places the pilot plant in its wider innovation context, as part of a Horizon Europe–funded effort to develop energy-efficient, sustainable drying solutions for fiber-based materials across Europe.

If you’re interested in:

  • Exploring energy and heat-recovery scenarios, or
  • Investigating how superheated steam drying affects product quality,

we’d be happy to discuss what’s possible on the pilot plant.

Superheated Steam Drying: the next step in dryer retrofits

At SteamDry we are advancing Superheated Steam Drying (SSD) from concept development to full‑scale industrial retrofit solutions. The core objective is to increase installed drying capacity and reduce specific energy consumption and CO₂ emissions, while keeping the existing machine as far as possible.

Three SSD concepts assessed on an industrial board machine

Within the project, three SSD configurations have been evaluated on a representative European packaging board machine: convective SSD, conductive SSD and a combined convective‑conductive SSD concept. Each option has been benchmarked against key KPIs: energy savings at machine level, required investment and payback time, runnability and product quality, and the practical feasibility of retrofitting into existing multicylinder dryer sections.

Superheated Steam Drying: From Concepts to the First Retrofit

Why the combined SSD concept is the lead candidate for the first retrofit

The combined SSD concept (convective + conductive) emerges as the lead candidate for the first industrial retrofit. It delivers strong energy savings with acceptable payback, while maintaining robust web handling and product quality and limiting layout changes in the dryer section.

Technically, a high‑intensity convective SSD module with superheated steam impingement is installed at the dryer front end to boost evaporation rate, followed by a conductive cylinder group operated in a steam‑rich environment that reuses part of the exhaust steam. This configuration enables reuse of existing dryer cylinders, reduces total capex compared to a full conductive SSD rebuild, and provides a more attractive retrofit pathway.

Enabling a realistic decarbonisation trajectory

By targeting retrofit‑friendly configurations instead of greenfield installations only, the combined SSD concept supports mill decarbonisation within realistic shutdown windows and investment cycles. Building on established impingement drying experience, the concept lowers technical risk, facilitates scale‑up from pilot to industrial scale, and shortens time to market.

Industrial Accelerator Act: A boost for low carbon, ‘Made in Europe’ process industries

The European Commission’s new Industrial Accelerator Act (IAA) is a clear signal that Europe intends to couple industrial competitiveness with climate ambition. The proposal aims to strengthen Europe’s manufacturing base, reduce dependence on non‑EU suppliers and scale up clean technologies, especially in energy‑intensive sectors such as steel, chemicals, paper and other process industries. By rewarding low‑carbon, “Made in EU” solutions and streamlining permitting for strategic industrial projects, the IAA seeks to accelerate investments that keep value creation, jobs and know‑how in Europe.

For SteamDry, this policy shift directly echoes our core mission: enabling radically more energy‑ and resource‑efficient drying processes for web‑like materials such as paper, board, tissue and nonwovens. Drying is among the most energy‑consuming steps in these value chains; reducing its energy demand and associated emissions is essential if European manufacturers are to stay both competitive and on track with climate targets. By developing and demonstrating superheated steam drying (SSD) as a high‑efficiency alternative to conventional drying, SteamDry offers exactly the kind of transformative process innovation that the Industrial Accelerator Act is designed to support.

Decarbonising a key industrial bottleneck

In paper and board production, drying can account for a major share of total energy use and CO₂ emissions across the line. Traditional drying systems are often constrained by efficiency limits and fossil energy inputs, making it difficult for mills to significantly cut emissions without compromising productivity or incurring very high costs. At the same time, rising energy prices and stricter climate policies are putting pressure on producers to modernise their assets and improve performance.

SteamDry addresses this bottleneck by advancing superheated steam drying technology that can drastically reduce the energy intensity of drying while maintaining or even improving product quality. By using superheated steam instead of hot air, SSD can recover and reuse heat more effectively, enabling substantial energy savings and lower specific CO₂ emissions. This kind of step‑change in process efficiency directly supports the IAA’s objective to prioritise low‑carbon technologies in energy‑intensive industries and to make European plants leaders in clean production.

Supporting ‘Made in Europe’ industrial competitiveness

The Industrial Accelerator Act places strong emphasis on strengthening European production capacity and rewarding solutions that are developed and manufactured in Europe. For process industries such as pulp and paper, this means that technologies which can be deployed in European mills—improving their cost position and emissions profile—are strategically important. Keeping these industries competitive is not only about avoiding carbon leakage; it is also about safeguarding local employment, regional value chains and industrial know‑how.

SteamDry contributes to this goal by focusing on solutions that can be integrated into existing or new European production lines. By targeting high energy savings and reduced operating costs, SSD has the potential to help mills remain economically viable while meeting increasingly stringent climate and sustainability requirements. This alignment between industrial performance, climate action and European value creation mirrors the core logic of the IAA: public policies and private investments should reinforce each other to build a resilient, future‑proof industrial base in the EU.

Enabling faster deployment through innovation and integration

A key challenge for industrial decarbonisation is not only developing new technologies, but also integrating them into complex production systems with minimal disruption and risk. This is where SteamDry’s broader innovation approach becomes particularly relevant. The project does not focus solely on the drying technology itself; it also works on digital tools, process integration strategies and control concepts that help optimise SSD within real‑world industrial environments.

By supporting smarter, more integrated process control, SteamDry makes it easier for manufacturers to plan, deploy and operate advanced drying systems in practice. This is fully consistent with the Industrial Accelerator Act’s intent to accelerate clean‑tech deployment by reducing barriers, clarifying investment signals and promoting technologies that are ready for industrial‑scale application. In this way, SteamDry serves as a concrete example of how Horizon Europe research can feed into the implementation of broader EU industrial and climate policy.

A role model for clean, resilient process industries

The Industrial Accelerator Act sets out a direction: a more resilient, “Made in Europe” industrial base that leads on low‑carbon production rather than following global trends. SteamDry shows what this can look like in practice for process industries that rely heavily on thermal energy. By combining cutting‑edge drying technology with a strong focus on implementation in real industrial contexts, the project helps create a pathway for mills and manufacturers to cut emissions, lower energy use and remain competitive from Europe, for Europe.

As discussions around the Act continue, projects like SteamDry will be crucial in demonstrating that ambitious climate policies and robust industrial performance can reinforce each other. Superheated steam drying is not just a technical upgrade; it is part of a broader shift towards cleaner, smarter and more resilient process industries that embody the spirit of Europe’s new industrial agenda.

World Energy Efficiency Day: How SteamDry cuts the hidden Energy of Industrial Drying

Every year on 5 March, World Energy Efficiency Day reminds us that the cleanest and cheapest energy is the energy we do not need to use. For SteamDry, this is a perfect moment to focus on one of industry’s “blind spots” for energy consumption: the drying of continuous web‑like materials such as paper, nonwovens and wood‑based products.​

What is celebrated on 5 March?

World Energy Efficiency Day has been marked since 1998, following an international meeting on rational energy use held in Austria, where 5 March was proposed as a global awareness date. Since then, it has been used to promote policies, technologies and behaviour changes that allow us to do the same (or more) with less energy, cutting costs and emissions without sacrificing quality of life or industrial competitiveness.

A global challenge: producing more with less energy

Worldwide, electricity demand continues to rise as we electrify transport, industry and digital services. Energy efficiency is the “first fuel” that helps curb this growth: in decarbonisation scenarios, efficiency improvements deliver a major share of the reduction in energy use and emissions, especially in energy‑intensive sectors like pulp and paper, chemicals and steel.

In Europe, the manufacturing of paper and paper products consumes hundreds of petajoules per year and relies heavily on heat for processes such as drying. That makes efficiency in drying a key lever for meeting climate targets while keeping the European industry competitive.​​

Drying: the big hidden consumer

Drying processes for web‑like materials are responsible for a very large share of thermal energy use in several industries. The SteamDry vision roadmap estimates annual drying energy demand in Europe at approximately:​

  • ~400 PJ per year in paper and board.
  • 1.4–2.2 PJ in wetlaid nonwovens.
  • 70–140 PJ in wood materials (panels, veneer, etc.).​

In many paper and board mills, drying alone accounts for more than 60% of total process heat demand. Conventional technologies – steam‑heated cylinder dryers, hot‑air impingement, through‑air (TAD) and infrared – typically use around 1,070–1,800 kWh of heat per tonne of paper in the drying section, often supplied by fossil‑fired boilers or direct gas‑fired air heaters.​

What SteamDry brings to energy efficiency

SteamDry (“Superheated steam drying for sustainable and recyclable web‑like materials”) is a Horizon Europe project (GA 101137906) designed to rethink how paper, nonwovens and certain wood products are dried. Its objectives include:​

  • Developing a high‑efficiency drying technology.
  • Achieving a CO₂‑emission‑free drying process.
  • Piloting superheated steam drying (SSD) for representative products.
  • Implementing advanced (AI‑supported) control systems and digitalisation.
  • Assessing environmental, techno‑economic and business impacts.​

The core is superheated steam drying (SSD), which replaces hot air in the dryer hood with circulating superheated steam in a closed loop. Steam is heated above its boiling point, passes through the dryer and mixes with the vapour coming from the product; part of this steam is then condensed to recover useful high‑temperature heat for other process steps, while the rest is reheated and reused. This allows SteamDry to:​

  • Improve heat transfer and reduce net energy consumption.
  • Minimise stack losses and recover high‑grade heat.
  • Eliminate direct combustion emissions in drying when energy input is electric and low‑carbon.​

How much can be saved?

Modelling work in SteamDry shows that for conductive cylinder dryers, combining SSD with advanced heat recovery, high‑temperature heat pumps and steam compression can reduce thermal energy demand by more than 50% compared with a reference case without heat integration. For impingement and TAD dryers, superheated steam enables optimisation of steam temperature, mass flow and heat recovery to balance efficiency, dryer compactness and integration with the plant’s overall energy system.​

Given that drying in paper and board alone accounts for around 400 PJ per year in Europe, out of roughly 650 PJ used in total for paper and paper products, the system‑level savings potential is very large. Additional savings are possible in nonwovens and wood‑based panels, where drying can represent up to 70% of process energy and specific heat demands between 0.8 and 2.7 MWh per tonne of product.​

A roadmap for the coming decade

The SteamDry roadmap describes a path from 2024 onwards, moving through laboratory, pilot, demo and flagship phases. During the project, partners develop critical elements such as leakage‑free sealing, steam purification, mechanical vapour compression, heat‑integration concepts and advanced control systems, both for rebuilds and new machines. Beyond the current project, the vision foresees larger demonstration lines and the first commercial‑scale retrofits towards the end of this decade.​

SteamDry joins the 2COOL2WASTE cluster

The SteamDry project has joined the 2COOL2WASTE cluster, a network of Horizon Europe projects collaborating to accelerate sustainable heating and cooling technologies across Europe. Through this step, the project positions its superheated steam drying (SSD) innovation within a wider portfolio of solutions for waste heat recovery, industrial decarbonisation and energy efficiency.

The 2COOL2WASTE cluster currently gathers 15 Horizon Europe projects: EEETHOS, EXQUISHEAT, GEOSYN, HEATWISE, HyCool-IT, I-UPS, MODERATOR, Push2Heat, RE-WITCH, SEEDS, SENERGY NETS, SPIRIT, SUSHEAT, THERMINATOR and THUNDER. Together, these initiatives cover a broad spectrum of solutions from high-temperature heat pumps and smart heat recovery to thermal networks, geothermal and seasonal storage, and advanced control systems for industrial and building applications.

Several projects in the cluster share a particularly close focus with SteamDry on industrial process heating and waste heat valorisation, including SUSHEAT, SPIRIT, Push2Heat, EXQUISHEAT, EEETHOS, HEATWISE and RE-WITCH. These projects address complementary parts of the value chain—such as high-temperature heat pumps for industry, electrified process heating, smart heat recovery and integration of waste heat into industrial systems—creating strong synergies with SteamDry’s work on energy-efficient industrial drying.

Within the 2COOL2WASTE cluster, the 15 projects work together on renewable heating and cooling, industrial waste heat recovery and advanced thermal energy management. By joining this initiative, the SteamDry project contributes expertise in high-efficiency industrial drying and benefits from knowledge exchange, joint events and cross-project collaboration on real-world decarbonisation solutions.

Participation in 2COOL2WASTE reinforces the alignment of SteamDry with key EU policy objectives, including the 2030 Climate Target Plan, the EU Bioeconomy Strategy, Processes4Planet and REPowerEU. Through the cluster, the project helps demonstrate practical pathways to reduce industrial energy demand, increase the reuse of waste heat and support a more sustainable and competitive European process industry.

Further activities within the 2COOL2WASTE community will feature SteamDry in joint communication actions, thematic webinars and dissemination materials that highlight progress and lessons learned from the project and its sister initiatives.
