HACK Digital Sea‘21

2-4 July, 2021

International online hackathon organized by the three Baltic States dedicated to the search for digital and innovative solutions that can promote the development of green ports, reduce pollution and the impact of shipping, preserve natural biodiversity, strengthen food value chains, promote the use of renewable energy sources, make more efficient use of logistics and create a socially friendly environment for all.

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, digital traceability of the seafood or the inability to use fish food waste efficiently. Excessive fishing, the use of bottom trawls and fisheries have caused great damage to the ecosystem of the Baltic Sea.

In addition, the climate of the sea has untapped potential – for example, biomass produced from macroalgae can be used as food and consumables, however, growing and harvesting macroalgae is still in its infancy in the Baltic Sea.

In this hackathon, we will look for sustainable fishing, innovative food and advanced technological solutions that enable untapped marine potential, increase biodiversity and address existing ecosystem challenges.

The Baltic Sea is the fourth most polluted sea in the world, which is severely affected by chemicals and eutrophication. It is the most densely trafficked sea in the world with as many as 2000 ships sailing at the sea at the same time. What is more, residents of port cities suffer from pollution that is dangerous to their health. Finally, due to the difficult climatic conditions, it is little studied.

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 could be a rapid step towards a more sustainable Baltic Sea ecosystem. These are the solutions that we are looking for!

Solution for monitoring of garbage/litter that enters the sea through rivers
Reducing eutrophication in the Baltic Sea
Collecting trash and harmful vegetation from beaches
Sustainable packaging
Automation of removing litter from rivers
Filtration method for rainwater piping
Dumped munition – wait or act?
Tracking and recording of the salt water dispersion
Real-time monitoring of water pollution
Efficient technology for the water area bottom treatment and pollution collection
Consumer education
Solutions for the detection of chemical and oil pollution 

Shipping is a particularly important part of the world's logistics infrastructure, which is closely linked to other means of transport (especially railways). Advanced logistics solutions allow goods to travel faster, keep food fresh and save fuel resources. Not everyone knows this, but the Baltic Sea is the most densely trafficked sea in the world. However, each untapped logistics opportunity has an impact on environmental, health and financial sustainability.

We expect smart, creative and innovative solutions that will enable more efficient use of logistics opportunities, from autonomous, environmentally friendly shipping solutions to more efficient delivery systems and their better integration into the entire transport infrastructure.

Sea transport integration into the entire transport infrastructure
Processing & distribution of quality during logistics
Digital traceability in seafood
Digitalisation of short food supply chain
Preserving the food quality during the transportation
Cargo planning

Blue energy is a huge untapped energy potential of the seas that will receive a lot of investment in the near future, 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. In addition, a variety of other advanced inter-marine power bridges connecting different countries and continents exist.

We invite you to offer innovative solutions that will help unleash and exploit the potential of marine energy!

The reduction of the impact of the sea energy on the environment
The reduction of the sea energy production costs
Prevention of noise generated by wind turbine farms on the environment
Sea water quality control under floating solar panels
