This project addresses challenges with federated learning for large-scale real-time use in autonomous vehicles. Autonomous vehicle systems rely on large amounts of multimodal sensor data, where centralized processing is impractical due to privacy concerns and communication limitations. The project aims to make federated learning more efficient by using self-supervised learning to train models with mainly unannotated data. The project will further investigate knowledge distillation as a possible solution for transferring knowledge between different models with varying architectures when the platform changes. 

To streamline data exchange in federated learning, methods for compression and aggregation are studied. A large multimodal dataset will be collected using a fleet of vehicles equipped with sensors. This dataset will initially be shared within the project consortium but with the goal of eventually make the dataset public. 

The project contributes to advanced digitalization of Swedish industry. The work is important for the Swedish automotive industry, but the knowledge and expertise gained will be applicable in all domains related to federated learning, multimodal data and where there is a large number of nodes with limited embedded resources. The project is based on a strong collaboration between Zenseact, Scaleout, AI Sweden and RISE, and is expected to lead to more robust and efficient distributed AI systems.

Many organizations still view drones as “just a gadget” rather than what they truly are: advanced IT systems that collect, store, and transmit sensitive information. As a result, organizations are implementing drone technology without considering cybersecurity, creating unexpected security risks for Sweden’s critical infrastructure.

The consequences of insecure drones are becoming increasingly serious – from data leaks and financial losses, which can be costly enough on their own, to something as severe as posing a national security threat.

Delaying action on drone cybersecurity is no longer an option – it’s not a question of if, but when the problem will arise.

We offer Drone Cybersecurity Assessments 

RISE has developed the Drone Cybersecurity Assessment – a comprehensive cybersecurity evaluation that gives you control over your drone systems before implementation. This service is specially designed for organisations working with societal critical activities, where cyber security and functional safety are crucial. By analysing both technical and regulatory aspects, you get a clear picture of the safety status of your drone systems before they are put into operation.

The service includes

• Network communication: Analysis of which external services the drone contacts during start-up and operation.
• Data encryption: Review of how data is protected – is it encrypted and safe?
• Physical safety: Assessment of the consequences of theft or physical access to the drone.

Why you should choose RISE

As Sweden's independent research institute, RISE has unique expertise in both drone technology and cyber security. With our security assessment, you get: 

• Mapping of how your drones handle sensitive information.

• Identification of safety vulnerabilities and action proposal before they lead to incidents.

• A competitive advantage in procurement where security is crucial.

• Protection against becoming a weak link in Sweden's security chain.

We collaborate with other areas of expertise 

To provide a comprehensive overview of your drone systems, we can also involve expertise in: 

• EMC testing – electromagnetic compatibility and interference immunity.

• Functional safety – especially for safety-critical systems.

• Energy and infrastructure – for robust integration in complex environments.

What happens after the evaluation?

You will receive an independent and detailed safety assessment, along with recommendations tailored to your needs and risk profile. The results can be used as a basis for decisions, procurement or further development of your drone systems.

The LÖST project documented and analysed the practical sub-exercises conducted as part of Total Defence Exercise DSM 2025. Through onboard and simulator observations, interviews and surveys, the project identified key lessons from the planning, execution and evaluation of the exercise.

The study found that the exercise strengthened cooperation between civilian and military stakeholders and improved understanding of roles, responsibilities and decision-making processes during heightened preparedness. The findings also highlight the importance of realistic scenarios, effective time management and structured debriefing in developing operational capability.

The project identified opportunities for improving future exercises, including greater realism, increased uncertainty within exercise scenarios, and a stronger focus on operational training for masters and bridge teams. The lessons learned can support the continued development of the shipping sector's total defence capabilities and provide guidance for other sectors planning similar preparedness exercises.

The project was carried out by RISE in collaboration with the University of Gothenburg and funded by Lighthouse.

The global transition to fossil-free energy sources has led to a rapid expansion of offshore wind power. The maintenance of wind power facilities requires specialised vessels, known as Service Operation Vessels (SOVs), which are often in operation for long periods at sea. At the same time, the shipping sector faces an urgent need to reduce its emissions in line with the EU Green Deal, the Paris Agreement and the International Maritime Organisation (IMO) climate strategy.

Liquid hydrogen – a zero-emission fuel

Liquid hydrogen is a promising fuel alternative due to its high energy density and the fact that when used, it produces only water as an emission – no carbon dioxide, nitrogen oxides, or particles. This makes LH₂ particularly interesting for maritime use, where achieving emission reductions is challenging with traditional solutions.

NAVHYS develops hydrogen systems for ships

The aim of NAVHYS is to develop an integrated system for the storage and use of liquid hydrogen in a maritime environment. Since LH₂ must be stored at -253°C, high demands are placed on insulation, safety and operation. The project brings together expertise from several sectors to develop a solution that is safe, energy-efficient, and easily integrated into future ship designs.

The goal – a new generation of emission-free ships

The overall goal is to demonstrate a complete LH₂ system on ships. This solution can then form the basis for a new generation of emission-free vessels in the offshore sector.

NAVHYS contributes to important climate goals

By replacing fossil fuels with LH₂ in service vessels, NAVHYS can contribute to:

•    The EU's climate neutrality goal for 2050
•    The IMO's goal of reducing greenhouse gas emissions from shipping
•    The sustainable expansion of renewable energy at sea
•    The development of hydrogen technology as a key component in the energy systems of the future

Gathering expertise from multiple sectors

A broad consortium of actors from the fields of ship design, operations, energy, safety and research is implementing NAVHYS. Together, we are developing a solution that can pave the way for a climate-neutral maritime sector.

Project timeline and funding

NAVHYS will run for 36 months and covers design, analysis, testing and dissemination. The project is funded by the Clean Hydrogen Partnership and the European Union, which supports research and innovation in hydrogen technology.

NAVHYS Project partners

The project is being run in collaboration between:

• ArianeGroup – coordinator and responsible for designing the system architecture and testing the solution
• Benkei – project management and coordination
• Bureau Veritas – technical review and approval
• ENGIE – design of the supply chain and bunkering station
• ERIG – communication and dissemination of the project

What does NAVHYS mean?

The project name, NAVHYS, is inspired by the Latin words navis (ship) and vis (power), combined with the first letters of hydrogen. Together, NAVHYS conveys the idea of ‘hydrogen power for shipping’.
