Creating the key enabler for energy transition

Feeding green energy into the system requires a certification process, as proving and validating the energy really being green is necessary for every producer.

Small green energy production, for instance households with solar panels, right now cannot be labeled and certified as ‘green’ and as such feeded back into the system: who can prove that it was really the solar panel producing the energy I am feeding back?

For the green energy market, this means that a lot of green energy producers right now have their energy traded as ‘grey’. Can we come up with a solution for small producers being able to certify their green energy, to have their data validated (near) real-time?

For this challenge, Vattenfall is inviting grid and energy data companies to work alongside the teams, to possibly create a standard for Europe. The goal is to create one of the key enablers to leapfrog energy transition, with an open protocol to ensure broad adoption, without additional hardware.


Business-, legal-, tax- and IT experts from Vattenfall
Vattenfall is in conversation with other stakeholders to form a consortium with all relevant parties within this value chain.


Specific dataset will be determined after talking to the team captains of the teams in this track, to individually help the teams.
Basic datasets of Vattenfall on the energy market and specific questions in the challenge will be available during the hackathon.




We are looking for protocol solutions, as in our vision the solution can only lift-off through an organized adaptive (eco)system. The competition can be on the commercial solutions building on top of this protocol.


Open source. We expect teams to build an open protocol that can be launched and adopted on an European level.


Vattenfall’s mission is to become fossil free within one generation.
Vattenfall is a leading European energy company, that for more than 100 years has electrified industries, supplied energy to people’s homes and modernised our way of living through innovation and cooperation.
We employ approximately 20,000 people and have operations mainly in Sweden, Germany, the Netherlands, Denmark, the UK and Finland. Vattenfall is owned by the Swedish state.

Ambition and goals

We want to make fossil-free living possible within one generation. Therefore we are driving the transition to a more sustainable energy system through growth in renewable production and climate smart energy solutions for our customers.
We need emerging technologies like blockchain, AI and Machine learning to reach that goal. Members of the Odyssey ecosystem build a new protocol layer to leapfrog energy transition and we will help them incubate and launch their solution.
Concrete ambitions with this challenge
As society, we need a <better>, <faster> and <cheaper> solution to create full disclosure in the flow of energy.

/<Better>: Good data, insight, clear, complete

/<Faster>: Real-time

/<Cheaper>: No additional hardware, low admin cost

We need a reliable system. Currently, only <large> green production is certified. <large>=1MW per month. Certificates are annually based. Certiq, the Dutch organization who is responsible and obliged to hand out these certificates, is operating by order of the Dutch Ministry of Economic Affairs and Climate Policy.

Paths to explore:

  • How can we create a reliable, single point of truth via blockchain/DLT?
  • How can we certify not only large-scale production but also small production on households?
  • How could you we use IoT to measure in-house consumption of the production of eg solar panels and measure feed-in without giving insight in the behavior of the energy consumer?
  • How can we estimate the usage of “old meters” and inverters without IoT connection with the use of AI/ML?
  • How can we be sure the produced energy is produced with renewable assets?
  • We have approx. 8mio meters we can use as data points, so how can we handle the Big Data?
  • To make the leapfrog in energy transition, we need insights to answer the above question, plan the bridge to the Paris agreement and execute the plan.

Track record in innovation and working to accelerate with teams/companies

Vattenfall over the last two years after the helped more than half the teams in their track with:
pitching before the board of Vattenfall
training on business
connections to internal and external stakeholders




Current consortium. Vattenfall is currently working on a full consortium with all relevant market players. We will update the website when parties have joined.


Welcoming. Distribution system operators (DSO), transmission system operators (TSO), Government, protocol foundations and experts on consortium forming on a European scale.




What does the partner offer. The consortium (still under development) will offer you the chance to instantly scale your solution throughout the energy market chain and on a European level.


Vattenfall will guide and support you in this process.


What do consortium partners offer. To be announced
