Energy Transition Outlook 2021 Summary

Core Content

The Energy Transition Outlook 2021 report, published by DNV, provides a comprehensive analysis of ten technologies that are expected to drive the global energy transition over the next five years. The report emphasizes the need for full energy-system thinking to understand the interdependencies and development timelines of these technologies. It highlights the importance of decarbonization as the central goal, aiming to reduce emissions by around 8% annually to align with the 1.5-degree ambition under the Paris Agreement.

Main Viewpoints

• Decarbonization is the priority: The world needs to transition rapidly to a deeply decarbonized energy system, which requires a combination of renewable energy expansion, improved efficiency, and carbon capture and storage (CCS).
• No single solution: There is no "silver bullet" for achieving net zero emissions by mid-century. A variety of technologies must be scaled and integrated to achieve the required reductions.
• Interconnected technologies: Technologies are not isolated; they are interdependent and interconnected. For example, the development of green hydrogen is closely tied to the progress of renewable electricity generation and storage systems.
• Cost learning rates (CLR): Costs for many technologies decline at a constant rate with each doubling of installed capacity. This is a self-reinforcing process that accelerates innovation and adoption.
• Policy and finance play critical roles: Governments and financial institutions are increasingly involved in driving the energy transition, with near-term policy actions playing a key role in shaping long-term goals.

Key Technologies

The report focuses on the following ten technologies:

Key Insights

• Floating Wind: Expected to grow significantly by 2050, contributing 250 GW to global electricity generation. It offers access to deep-water wind resources and is technically viable, though current costs are high (LCOE over 200 USD/MWh). DNV expects costs to fall by 70% by 2050, making it more competitive.
• Solar PV: The fastest-growing renewable energy source, with global capacity projected to reach nearly 3,000 GW by 2030. Innovations such as bifacial panels, PERC technology, and TOP-con are driving efficiency and cost reductions.
• Interconnected Systems: Technologies like floating wind, solar, and green hydrogen are interconnected. For example, the success of green hydrogen depends on renewable energy availability, storage, and transport capabilities.
• Digitalization and Innovation: Digital tools such as demand response, network storage, and digital twins are enhancing the flexibility and performance of the energy system.
• Global Collaboration: The report underscores the importance of international standards, shared data, and joint industry projects in accelerating the transition and reducing costs.

Challenges and Opportunities

• Cost Reduction: While some technologies like solar PV and EVs are already seeing rapid cost declines, others such as green hydrogen and floating wind require further innovation and standardization to achieve cost competitiveness.
• Deployment and Scaling: Scaling technologies from prototypes to global deployment is a critical challenge. For example, green hydrogen must overcome supply chain and infrastructure barriers.
• Regulatory and Policy Support: Clear regulations and incentives are essential to attract investment and drive the global adoption of these technologies.
• Industry Cooperation: The report highlights the need for collaboration between different sectors, especially in maritime and offshore wind, to ensure the success of the energy transition.

Conclusion

The Energy Transition Outlook 2021 underscores that the next five years will be pivotal for the global energy transition. It calls for objective, realistic assessments of technology progress and highlights the interconnected nature of the energy system. With the right policies, investments, and collaboration, these technologies can help the world achieve its net-zero goals by mid-century.
