City to Sea Hackathon | Mobility


Mobility is the transportation of goods, services, and people from one location to another. It involves the usage of different vehicles, logistics systems, and IoT, including the development of future technologies. 

Future challenges ahead include growing urban populations, how to build and maintain infrastructure, the economic and environmental costs of congestion demands for greater accessibility and safety, and the question of how to improve air quality.

City to Sea Hackathon | Acquaculture


Aquaculture is the controlled process of cultivating aquatic organisms, especially for human consumption. It’s a similar concept to agriculture, but with fish instead of plants or livestock.


Aquaculture is also referred to as fish farming. The seafood that you find at your local grocery store is likely labelled as farmed fish. Aquaculture can happen all over the world, and it does: in coastal ocean waters, freshwater ponds and rivers, and even on land in tanks.



Anyone with or without an idea is welcome to participate:
- students
- engineers
- entrepreneurs
- programmers
- creatives
- startups
- etc.
are welcome to join the City to Sea 48h hackathon.

The matchmaking platform will help you find a team to join or the skill set that your team is missing to thoroughly develop your idea during the hackathon.  



01 Register as an individual (Business, Design/Creative, Theme Expert or Technical specialist)


02 Create a team or join others


03 Develop and test your idea and win prizes 

01 Register each team member as an individual

02 Create your team/idea profile


03 Develop and test your idea and win prizes 




While you are welcome to participate with any idea to solve mobility and aquaculture challenges, we offer a few topics to help you brainstorm.

City to Sea Hackathon | Active mobility challenge

Active Mobility

Active mobility has a huge potential to improve healthy city living and decrease noise and air pollution. 


This challenge is about finding tools and solutions that can help citizens to change their daily transportation habits into healthier ones. 


The solutions can be revolutionary bicycle storage solutions, gaming active mobility, or even simple infrastructure adaptations.

City to Sea Hackathon | Precision fishing and aquaculture challenge

Precision Fishing and Aquaculture

The Baltic Sea is an important part of our food systems. 


However, the low level of exploration of the Baltic Sea poses a number of challenges, such as poor fish nutrition, migration, disease detection, and digital traceability of the seafood. 


In addition, the climate of the sea has untapped potential that can be used to solve challenges, for example, biomass produced from macroalgae can be used as food and consumables.

City to Sea Hackathon | Micro mobility and sharing economy challenge

Micro Mobility and Sharing Economy

Free Floating vehicles are very important to promote sharing economy which reduces the number of cars in cities and improves urban mobility.


However, they are often cluttering the public spaces in the city, thereby decreasing the quality of life as they tend to be found in inconvenient places for residents.


This challenge looks for solutions that could improve access, usability, and the private sector's willingness to participate in the business model. They could be micro mobility platforms, new MaaS or device monitoring solutions. 

City to Sea Hackathon | Environmental sustainability challenge

Environmental Sustainability

The Baltic Sea is the fourth most polluted sea in the world and the most densely trafficked sea.


This challenge is about finding digital solutions enabling the development of green ports, the collection of data in the Baltic Sea, the identification of sources of risk, the reduction of the impact of pollution and shipping, and innovative educational approaches.


These solutions could be a rapid step towards a more sustainable Baltic Sea ecosystem. 

City to Sea Hackathon | Pollution restriction challenge

Pollution Control

Pollution in cities takes many different forms: air pollution, light pollution, sound pollution, etc.

Every pollution can be measured and reduced. 


While monitoring systems have complex installation processes, there must be solutions that enable the private and public sectors to track noisy and unwanted vehicles!? We are also looking for solutions that work as traffic calming devices. 

City to Sea Hackathon | Digitalisation and supply chain challenge

Digitalisation of Supply Chains

Smart, creative, and innovative solutions could enable more efficient use of logistics opportunities.


Things like autonomous, environmentally friendly shipping solutions, more efficient delivery systems, and better integration into the entire supply chain could be the key to that.

City to Sea Hackathon | Sustainable energy for mobility challenge

Sustainable Energy for Mobility

Sustainable energy sources are crucial to maintain the good effects of new mobility solutions.


This challenge calls for solutions that improve the access to EV charging stations, increase the efficiency of electricity grids and help society to employ any possible space and area towards sustainable energy generation.


At the same time, it is important to look for solutions that facilitate faster transfer toward renewable energy sources.

City to Sea Hackathon | Sea energy challenge

Marine Energy

Blue energy is a huge untapped energy potential of the seas that will receive a lot of investment, generate significant economic returns for society and help protect the environment. 


The European Commission has set a target to scale up the amount of renewable energy from the sea 5 times by 2030 and even 25 times by 2050.


We are looking for solutions that can fulfill this goal!
