Energy Transition Outlook 2021 Summary

Core Content

The Energy Transition Outlook 2021 report by DNV provides a detailed analysis of ten technologies that are pivotal in the global shift to a deeply decarbonized energy system. The report emphasizes the need for full energy-system thinking to understand the interconnectedness of technologies and policies, and to make strategic decisions that will enable the world to meet the 1.5-degree climate goal set by the Paris Agreement.

Main Viewpoints

• Decarbonization is urgent: The world must reduce emissions by approximately 8% annually to align with the Paris Agreement.
• No single solution: There is no "silver bullet" for achieving net-zero emissions; instead, a combination of technologies and policies is necessary.
• Technological progress is key: The development and integration of new technologies are essential for accelerating the energy transition.
• Cost learning rates (CLRs): Costs for technologies typically decline at a constant rate with each doubling of installed capacity, and this process is self-reinforcing.
• Interconnected systems: Technologies are not isolated; they interact and depend on one another, which is critical for system-wide progress.

Key Technologies Covered

The following ten technologies are highlighted as being at the forefront of the energy transition:

1. Floating Wind
2. Developments in Solar PV
3. Waste to Fuel and Feedstock
4. Pipelines for Low-Carbon Gases
5. Meshed HVDC Grids
6. New Battery Technology
7. Novel Shipping Technologies
8. EVs and Grid Integration
9. Green Hydrogen Production
10. Carbon Capture and Storage (CCS) 2.0

Expected Developments

• Floating Wind: Is expected to grow significantly, reaching 250 GW by 2050. Initial high costs are projected to drop by 70%, making it competitive with bottom-fixed wind.
• Solar PV: Will continue to grow rapidly, with global capacity expected to reach nearly 3,000 GW by 2030. The technology is expected to become the lowest-cost power source in most markets.
• Technology Interdependence: Technologies such as green hydrogen, EVs, and battery storage are interdependent, and their combined use can significantly enhance system flexibility and efficiency.
• Cost Reduction: The report outlines how cost reductions are driven by scale, innovation, and experience, with core technologies (e.g., solar PV, batteries) showing faster learning rates than supporting technologies (e.g., BOS materials).

Challenges and Opportunities

• Early-stage technologies like green hydrogen and nuclear fusion require scaling and global cooperation to become commercially viable.
• Regulatory and policy support is crucial to accelerate the transition, as the current shift is more policy-driven than previous market-driven transitions.
• Standardization and sharing of operational data are necessary for the industry to progress and reduce costs.
• Industry collaboration is essential to overcome technical and market barriers, especially in sectors like shipping and energy infrastructure.

Conclusion

This report serves as a complement to the main Energy Transition Outlook and provides an objective assessment of the status and future of these key technologies. It underscores the importance of innovation, investment, and integration in achieving a low-carbon energy future by mid-century. The next few years will be pivotal for these technologies, as their scaling and integration will determine the success of the global energy transition.
