1. Including more renewables in the energy system. I am looking at a technology (Power-to-Gas) that converts electricity to hydrogen by breaking down water to hydrogen and oxygen. So when there is an excess of wind or sun, and we are not using it, then we can store that electricity as hydrogen and use that hydrogen for power generation later when we need it.
If you can check out my talk on my thesis, it is only three minutes https://www.youtube.com/watch?v=hfqD3tUp5rU&t=44s
2. I am also looking at how the gas demand will change in the future, and how renewable gas/electricity can be used to meet it.
