Skip to 0 minutes and 9 secondsIn your opinion, what role will energy storage play in the future? I think it will play a major role. Let's look at a typical family. They will have an electric car. They will also have a local battery in the home. That means and they'll probably also have local production, like a solar panel. So they will, in a part somehow they will be more independent. But they will also need a centralised system, but to a lesser degree. And in terms of reliance, they know they can have electricity, even if the grid breaks down for hours. They know that they have a clean car. They can travel with a clean car.

Skip to 0 minutes and 52 secondsThey can even fill up the car in their home, which you cannot. No one has a gas station at home. And I think overall, also, the additional benefits - we haven't even talked about this - that these vehicles it's not only that they emit less carbon dioxide. They're also quiet. They are roomier. Typical electric car, for the same auto size, is bigger inside. So it's like for me, it's a dream scenario. Everything is better. And what is the affordability for this, for an everyday user, putting these applications of batteries within their home? I imagine that will save a lot of money long term, but what about the setup? And what does the affordability look like for an everyday user?

Skip to 1 minute and 40 secondsWell, I think this is one of the tricky questions, in fact, that because if you invest in private homes, for instance, with storage and then you make it more affordable to build grids. But the problem, of course, that you must have a payback in terms of a lesser-grid fee. For the electric car, then I think it's quite obvious that the running costs are lower. You will also have less maintenance. And in fact, the car will last longer as well, because electric motors, they last forever compared to the car. And electric vehicles obviously, we're seeing a bit of an increase.

Skip to 2 minutes and 21 secondsAnd in what year do you think that electric vehicles are going to be something that everybody owns or will start owning more of? And what does the future look like with electric vehicles for every-day people?

Skip to 2 minutes and 35 secondsI think there again that if I say 2025, in 2025, I think it would be very difficult to sell a conventional car, fossil car, because the electric car will have same or lower cost and much lower on running costs and, as I said also, lower cost for operations. So and this is something I don't think people realise, that we come to, I will say, a break point, where the fossil car has no advantages left, because the range will be sufficient. We will have charging infrastructure that helps you. And at that point, again, I think we will see a quite dramatic turn. We are seeing that in other areas.

Skip to 3 minutes and 17 secondsI mean, we all know, for instance, when flat-screen televisions started being introduced. They were quite expensive. There were not much better, maybe even worse than the traditional ones. But once they reached a point where the cost was so affordable and the performance, technical performance, was good enough, in a very, very short time, everyone changed their buying pattern. And that's what we'll we see with the cars as well. And batteries within an electric vehicle and also the home what is the amount of time that people can survive on that battery within a vehicle and at home? Again interesting, because if you combine the battery, because, I think, the battery in the home you will need for shorter term.

Skip to 4 minutes and 1 secondBut the battery in the car will be the biggest battery you have. And that, even if you have, we have looked at-- even if you have electric heating and you have a typical electric car, you can actually survive for days with the battery in the car. So it's an extremely robust system. Of course, all of us we don't live in single family homes. But still, that I can see that the garage you have for a community will actually also be the storage for the community. And again, I think that we have not fully realised how much that will mean for the resilience in the system, and also how much it needs in terms of flexibility.

Skip to 4 minutes and 48 secondsWe can decide more locally, and we are less dependent on the overriding structure, traditional structure. And where does capacity come into all of this? Capacity in terms of? Hydrogen storage. Yeah. Hydrogen storage is, we haven't mentioned that so much. But hydrogen storage will be very, very important, because we talk about renewable systems that are producing. And assume now that we have we have a very windy day, and not for hours, but for days. Then we will overproduce electricity. And we have made some simulation that shows that in a typical electric system, we might have, like, 20% of the time, we have too much electricity. And then the batteries can all not take all that.

Skip to 5 minutes and 38 secondsAnd then of course, hydrogen is beautiful way to storage. And then you can store almost endless amounts of power, because storage is very cheap once you transform it into hydrogen. And then you can use the hydrogen in industrial processes. You can use it in heavy vehicles, I believe, and to some degree, also, in cars. So if you could summarise battery storage within transportation and the power sector, what would you have to say as a final remark? Well, I think the final remark will be that batteries will be a transformation, lead to a transformation of both these sectors. It is quite unusual that the same technology is affecting two sectors at the same time.

Skip to 6 minutes and 23 secondsIt could also mean that these two sectors are merging. I want to mention that the car becomes a part of the power system, and the power system becomes, actually, a part of, also, the car. So you merge two areas, in fact. And would you say it's going to be 100% renewable? That for me is a given, because we have that as a target in many countries. And I would say the batteries will make that vision become real. Thank you

Energy storage and the future of energy

How will energy storage change the way we live and work? What exactly does the future of energy storage look like for the transportation and the power sectors? Is a 100% renewable energy system an achievable target? Bo Normark, Thematic Leader for Smart Grids and Energy Storage at InnoEnergy explains how we will start seeing obvious transformations by 2025, and what the average modern home will look like. Let’s hear from Bo.
