Energy Storage and the Path to 100% Renewables: Past, Present, Future

With renewables proliferating the grid globally the barrier to replacing fossil fuels is no longer the cost of wind and solar technology. At low levels of penetration these energy sources are being adopted readily, but at higher levels we’ll see economics fall, grid stability concerns arise and a need for energy storage to further continue reductions in fossil fuel use. We are beginning a second stage of incorporating more renewables using storage, but what barriers will be presented next? The costs of today’s lithium batteries are still decreasing but can they decrease ‘enough’ to get to 100%? How much CO2 emitting production can be offset with today’s technologies and which chemistries or non-battery storage solutions are available tomorrow? Even if initiatives like SEPA’s Renovate clear the way for policy is it practical from a technology standpoint that we ever get to 100%? This presentation addresses these questions by outlining the path storage and renewables penetration will take using information from DNV GL’s ETO - a global energy analysis to 2050, insights into current and future storage technologies and modelling grids with high penetration renewables.
