With the increasing importance of renewable energy, grids must deal with the variability and intermittency of renewables generation. DNV talks to Paul Gardner, Segment Director - Storage at DNV, on the ongoing developments ensuring that storage solutions can support the growing energy demand. Our Energy Transition Outlook 2017 report concluded that the electricity demand will rise by 140% by 2050, and of this, 72% will be generated by renewables. However, with this transition comes challenges on output consistency. In this insightful interview, Paul gives an overview of the current solutions that will support and optimize renewable energy in the future, with a focus on storage. He explains the different options available; their most appropriate usage; and considers why some available storage technologies may no longer remain efficient in the future. Finally, as cost is often at the forefront of power generation discussions, Paul addresses what can be done to lower the cost of storage in the future . *This episode was recorded live at the Singapore International Energy Week 2017.
