A multitude of innovative solutions have been key to making renewables into the competitive energy option that they are today. The pace of renewable energy innovation, meanwhile, keeps accelerating, with power generation solutions at the forefront. Rapid cost reductions for solar and wind power have put these technologies at the core of the energy transation. To maximise their share while maintaining low electricity costs, more flexible power systems are needed. Innovation programmes in leading markets, therefore, are focusing on solutions to achieve maximum power system flexibility. The increasing electrification of transport, buildings and industry can also facilitate solar and wind uptake if smart approaches are adopted. As many of these new loads will be flexible, their inclusion in the power system can also help to integrate more renewables through demand-side management strategies. Many of the solutions to address such challenges are ready for commercialisation. With pioneering companies creating, trialling and deploying a swathe of potentially transative innovations, the key trends of digitalisation, decentralisation and electrification are moving ahead faster than anyone expected. Yet timely, focused government action remains essential to support innovation and integrate emerging solutions. In each context, decision makers need to identify the optimal combination of solutions. Determining a suitable, tailored innovation mix for each country requires a systemic approach – combining innovations in technology with those in market design, business models and systems operation. But the sheer diversity of solutions available, coupled with the diversity of power systems around the world, can pose significant challenges in decision-making. FOREWORD5FOREWORDAdnan Z. AminDirector-GeneralInternational Renewable Energy AgencyThe present Innovation Landscape study, prepared by the International Renewable Energy Agency IRENA, aims to provide a clear and comprehensive guide to such solutions. It seeks to support ined decision-making, assist in the creation of enabling policy frameworks, help nurture targeted innovation and, ultimately, facilitate the accelerated transition to renewables. The present report maps and categorises examples of the innovations being developed and implemented globally to facilitate the large-scale integration of variable renewable power. This main report will be augmented by innovation briefs and online resources which will permit closer examination of each innovation type. The study highlights the broad range of innovations available that could not just accelerate renewable energy deployment to meet demand, but could also help to ensure that the energy transation is global and inclusive. IRENA will continue to work with its Members on fostering renewable energy innovation and deployment, in line with their national economic, social and environmental goals as well as with global climate and sustainable development objectives.

Around the world the pace of developing and introducing better, more efficient renewable energy technologies is accelerating. Renewables are becoming the go-to option for many countries in their transition towards a secure, cost-effective and environmentally sustainable energy supply. Renewables underpin continued socio-economic development with jobs and local value creation, while simultaneously combating climate change and local air pollution. The power sector has led the way, with rapid reductions in the cost of solar and wind technologies resulting in widespread adoption in many countries. Despite the promising progress to date, however, the pace of the energy transition needs to pick up significantly. As with market policies, the policies put in place to drive technological innovation should be continually revisited and updated to keep up with new developments and breakthroughs IRENA, IEA and REN21, 2018.The integration of variable renewable energy VRE poses specific challenges as its share of power generation rises – in essence, maintaining the balance of supply and demand becomes more of a challenge. More flexible and integrated power systems are needed to maximise the value of low-cost VRE, meaning solar and wind.In response, policy makers and system operators around the world are adopting a range of measures to maintain an affordable and reliable balance of supply and demand in this evolving landscape. Innovation is focused on fostering the development and deployment of solutions that increase the system flexibility needed to integrate high shares of solar and wind power. CUTIVE SUMMARYFlexibility The capability of a power system to cope with the variability and uncertainty that solar and wind energy introduce at different time scales, from the very short to the long term, avoiding curtailment of power from these variable renewable energy VRE sources and reliably supplying all customer energy demand IRENA, 2018c.Variability The fluctuating nature of solar and wind resources, which translates into potentially rapid changes in electricity outputUncertainty The inability to predict perfectly the future output of solar and wind power sources9In recent years far-sighted governments and pioneering companies around the world have been creating, trialling and deploying a multitude of innovative solutions that have the potential to radically trans energy systems across the world. The sheer diversity of solutions, coupled with differences between local energy systems, may make for a confusing picture for decision makers, who may struggle to identify and assess the best solutions for each country or context.The International Renewable Energy Agency IRENA has conducted an extensive and detailed analysis of the innovation landscape for the integration of variable renewable power, mapping and categorising t
