How will government support electrochemical storage?

New research promoting soft-side innovations and business models will expedite integration of electrochemical storage into common markets. Further government support is necessary to promote responsible R&D spending that enables serious cost reductions across solar, wind, and storage, while also decarbonizing electricity and transportation.

What is the share of energy-related R&D?

The dark green dots show a similar development for the share of energy-related R&D to total R&D spending. In the late 1970s, energy R&D accounted for over 10% of total R&D, of which more than 50% was allocated to nuclear energy globally.

How can battery storage help reduce energy costs?

Simultaneously, policies designed to build market growth and innovation in battery storage may complement cost reductions across a suite of clean energy technologies. Further integration of R&D and deployment of new storage technologies paves a clear route toward cost-effective low-carbon electricity.

Will electricity storage benefit from R&D and deployment policy?

Electricity storage will benefit from both R&D and deployment policy. This study shows that a dedicated programme of R&D spending in emerging technologies should be developed in parallel to improve safety and reduce overall costs, and in order to maximize the general benefit for the system.

How much would a residential solar+storage project cost?

This would place residential solar+storage at an estimated US$0.11–0.12 kWh −1 target. Based on a ten-year project lifetime, and in the optimal case assuming a full charge–discharge cycle on a daily basis ignoring losses, LCOE at current prices is US$0.15 kWh −1 at residential scale and US$0.10 kWh −1 at utility scale.

How has battery storage changed the world?

Wider deployment and the commercialisation of new battery storage technologies has led to rapid cost reductions, notably for lithium-ion batteries, but also for high-temperature sodium-sulphur (“NAS”) and so-called “flow” batteries. In Germany, for example, small-scale household Li-ion battery costs have fallen by over 60% since late 2014.
