    About this ebook

    Nuclear energy and renewables are the two principal options for low carbon energy generation. However, synergies among these resources have yet to be fully exploited, and the advantages of directly integrating these generation options are being explored. Nuclear-renewable hybrid energy systems consider opportunities to couple these energy generation sources to leverage the benefits of each technology to provide reliable, sustainable electricity to the grid and to provide low carbon energy to other energy use sectors. This publication describes the potential use of nuclear and renewable generation in coordinated, and in some cases tightly coupled, configurations to support various applications beyond electricity production, including desalination, hydrogen production and district heating. Where available, case studies are presented to describe relevant market conditions and trends, and considerations for implementation are outlined, including gaps that require additional technology and regulatory developments.

      FOREWORD

      The IAEA’s statutory role is to seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world. Among other functions, the IAEA is authorized to foster the exchange of scientific and technical information on peaceful uses of atomic energy. One way this is achieved is through a range of technical publications including the IAEA Nuclear Energy Series.

      The IAEA Nuclear Energy Series comprises publications designed to further the use of nuclear technologies in support of sustainable development, to advance nuclear science and technology, catalyse innovation and build capacity to support the existing and expanded use of nuclear power and nuclear science applications. The publications include information covering all policy, technological and management aspects of the definition and implementation of activities involving the peaceful use of nuclear technology. While the guidance provided in IAEA Nuclear Energy Series publications does not constitute Member States’ consensus, it has undergone internal peer review and been made available to Member States for comment prior to publication.

      The IAEA safety standards establish fundamental principles, requirements and recommendations to ensure nuclear safety and serve as a global reference for protecting people and the environment from harmful effects of ionizing radiation.

      When IAEA Nuclear Energy Series publications address safety, it is ensured that the IAEA safety standards are referred to as the current boundary conditions for the application of nuclear technology.

      Two principal options for low carbon energy are renewables and nuclear energy. While many Members States have expressed interest in these options, possible synergies between them and potential integration options have not been fully explored. Nuclear–renewable hybrid energy systems integrate these energy generation sources to leverage the benefits of each technology for improved reliability and sustainability. Nuclear–renewable hybrid energy systems can produce heat, electricity and other products that society requires while supporting higher penetrations of variable renewable generation (i.e. wind and solar photovoltaics). Nuclear–renewable hybrid energy systems can include various applications, such as seawater desalination, hydrogen production, district heating or cooling, the extraction of tertiary oil resources and process heat applications, such as cogeneration, coal to liquid conversion and assistance in the synthesis of chemical feedstock.

      In October 2018, the IAEA held a Technical Meeting on Nuclear–Renewable Hybrid Energy Systems for Decarbonized Energy Production and Cogeneration. This meeting proposed the development of an IAEA publication on nuclear–renewable hybrid energy systems. This publication provides high level information to decision makers and stakeholders, including that necessary when considering nuclear–renewable hybrid energy systems.

      This publication presents opportunities for nuclear–renewable hybrid energy systems that could be pursued in various Member States as a part of their future energy mix. It describes the motivation for and potential benefits of nuclear–renewable hybrid energy systems relative to independent nuclear and renewable generation producing electricity alone. Considerations for implementation are outlined in the publication, including gaps that require additional technology and regulatory development. This publication intends to equip decision makers and stakeholders with sufficient information to consider nuclear–renewable hybrid energy systems as an option within regional and national energy systems.

      The IAEA officers responsible for this publication were T. Jevremovic of the Division of Nuclear Power and A. van Heek of the Division of Planning, Information and Knowledge Management.

      SUMMARY

      Nuclear energy and renewables are the two principal options for low carbon energy generation. However, synergies among these resources have yet to be fully exploited, and the advantages of integrating these generation options directly are only now being explored. Nuclear–renewable hybrid energy systems (HESs) consider opportunities to couple these energy generation sources to leverage the benefits of each technology to provide reliable, sustainable electricity to the grid and to provide low carbon energy to other energy use sectors.

      The transition of the global energy mix to include increasing fractions of variable renewable energy resources is driven by economics as well as social development concerns. While introducing new challenges, this transition also presents potential synergies and opportunities for sustainable development. In particular, the proposed coupling and/or tighter integration of nuclear and renewable resources appear to be mutually beneficial.

      This publication describes the potential use of nuclear and renewable generation in coordinated, and in some cases tightly coupled, configurations to support various applications beyond electricity production, including seawater or brackish water desalination, hydrogen production, district heating or cooling, the extraction of tertiary oil resources, and process heat applications such as cogeneration, coal to liquids conversion and assistance in the synthesis of chemical feedstock. Where available, case studies are presented for these configurations to describe relevant market conditions and trends, energy requirements and research gaps in order to clarify the opportunities and issues associated with the proposed nuclear–renewable HESs.

      Considerations for implementation are outlined, including gaps that require additional technology and regulatory developments. This publication intends to equip decision makers and stakeholders with sufficient information to consider nuclear–renewable
