When disasters related to climate change, such as hurricanes or extreme floods hit and power goes off, fossil fuel-based nanogrids often act as temporary relief. In reality, they contribute to the climate crisis ultimately causing other disasters. Solutions as simple as nanogrids powered by renewable sources can help those affected while also helping our transition into a renewable future. 'Sesame Solar' is one such solution. The fully mobile nanogrid is powered by a combination of solar panels and green hydrogen. When needed, it can be easily transported to affected areas. The system comes ready to use and requires minimum training to set up. Its creators claim that the nanogrids, which can be operated by a single person, are able to withstand extreme weather conditions such as hurricanes and heavy floods.
