VTT Guide

Overcoming bottlenecks in green energy transition

Full of potential, but also presenting complex challenges, what does green energy transition require from companies? VTT's new guide presents five bottlenecks and the latest solutions to make the change successful.

Our energy system is facing an inevitable transition: fighting against climate change requires cleaner and more affordable energy production, as well as finding more efficient ways to distribute and use energy.

A new energy system is already developing rapidly, and companies want to move towards the growth opportunities. However, the journey is not without challenges.  

Five bottlenecks and how to solve them

  1. New dynamics challenge the operation of the energy system
  2. Conflicts between sustainability impacts
  3. Integration and complexity are 
    challenging our energy resilience
  4. Limited availability of critical raw materials
    slows down the green transition
  5. Today's decisions will impact
    future generation

The 45-page guide presents three solutions for each of these. For each solution, we describe the practical actions with timetables for putting the solutions into use and bringing them to the market.

From resilient districts and building-as-a-battery concepts to hydrogen and SMR for local energy production, this guide is based on world-class research and innovation from VTT together with its specialist partners.

Future-proof your strategy for the green transition.
