Summary of IRENA's Innovation Landscape for Smart Electrification: Decarbonising End-Use Sectors with Renewable Power

Core Content

IRENA's Innovation Landscape for Smart Electrification: Decarbonising End-Use Sectors with Renewable Power (2023) outlines a comprehensive set of innovations aimed at accelerating the transition to a low-carbon energy system by integrating renewable power into end-use sectors such as mobility, heating/cooling, and hydrogen production. The report emphasizes the need for a systemic and coordinated approach to energy transformation, focusing on both supply-side and demand-side innovations.

Main Views

• Smart Electrification as a Decarbonisation Tool: The report highlights that smart electrification is crucial for decarbonising end-use sectors. It involves not only the adoption of electric vehicles (EVs) and heat pumps but also the integration of these technologies with renewable energy systems.

• Innovation as a Key Driver: Innovation is presented as the central force behind the global energy transition. It includes technological, infrastructural, market, regulatory, and business model innovations that together enable the efficient and sustainable use of renewable energy.

• Need for Policy and Market Support: The report stresses that while many smart electrification solutions are available, government support through policy, market design, and investment is essential to scale these innovations and ensure their successful integration into national energy systems.

• Systemic Integration: The energy system must be restructured to allow for the seamless coupling of power generation with end-use applications. This includes system planning, operation, and the development of new business models that support the transition.

• Global Investment Trends: Global investment in energy transition technologies reached USD 1.3 trillion in 2022, but it needs to quadruple to meet the 1.5°C Scenario. This includes investments in energy storage, electrolyzers, and other emerging technologies.

• Role of IRENA: IRENA acts as a global platform for renewable energy innovation, offering a toolbox of 100 innovations that can be tailored to national contexts to support the decarbonisation of end-use sectors.
