Renewable energy's potential can be maximized with storage solutions, ensuring green power availability even when wind and solar generation are low.
Renewable energy production has been increasing over the past few years. Yet, to fully exploit its potential and compensate for the intermittency of sun and wind, storing power for later use is crucial. Batteries are an essential component of the future energy system, which is becoming increasingly decentralized and flexible. They provide more stability to the electricity grid.
As the world electrifies, you probably think of batteries as lithium-ion ones. But there is much more happening in this space. Batteries can also be made with sodium, salt, and water–widely available materials that will make this technology cleaner and more affordable than it already is.

After installing solar panels on your rooftop, you have learned to turn on the washing machine or charge your electric car when the sun is shining. Still, as you generate more electricity than you need, you are also likely feeding some of that electricity back to the grid. Yet, at night, you have to draw power from the electricity grid. To maximize the benefits of having installed solar panels, you might want to store that energy. How to do so? The answer is straightforward: installing a home battery.
While several options are already available on the market, we highlight here a couple of innovative solutions that you may not have heard of. Newton Energy Solutions' NEStore converts electricity from solar panels or the grid into heat, storing it without heat losses in water for weeks. When discharged, the system delivers hot water. In this story, you can find out more about the technology.
Here is an introductory video by the company:

Are you looking for a compact storage solution? Planetpod has got you covered. The company has developed a home battery system specifically tailored to the Dutch market, offering a compact-sized battery capable of storing enough electricity to power a household while minimizing bulk. Do you know what is also cool about this company? It was founded by two young brothers who are making strides to enable more people to self-consume the energy they generate. I previously interviewed Maurice van der Ende for the Green Transition Drivers series.
