The Future of Battery Storage

We're seeing some really positive movement in Japan and it does echo I suppose some of what we also saw in solar over the last decade. So Japan is very much a focus for us in the Asia-Pacific region. And just to maybe finally just on price of battery storage, you've obviously been looking at this project and you've got other projects in the pipeline. What have you observed and what do you predict? We've seen prices move around significantly. From the time we made the final investment decision on Haserwood to where we are today we've probably seen peak to trough close to 50% movements in price.
