When I first read the titile, I thought that the US is going to have to build A LOT to triple global production. Then it occured to me that the author means the US is pledging to make deals and agreements which enable other countries to build their own. Sometimes I think the US thinks too much of itself and that’s also very much part of American branding.
Where are my renewable bros at? Tell me this is bad.
That is a battery. But the type of battery it is describing doesn’t actually exist.
Grid-scale storage doesn’t necessarily mean lithium batteries. It could mean redox flow batteries, it could mean pumped hydro, it could mean gravitational potential storage, it could mean pressurised air in abandoned mineshafts. It could even mean smart grids with dispatched domestic batteries and dispatched EVs reverse charging back to the grid.
Nuclear is a great energy source, but it’s not renewable. If we start rolling out nuclear all over the world on a large scale, we would sooner or later run out of nuclear material. I’ve heard estimates as high as 200 years, and as low as 50 years. The long-term future has to be something renewable, and all the renewable energy sources we currently know of are intermittent. Therefore there needs to be some sort of storage to smooth out the short term discrepancy between generation and consumption.
I do believe nuclear has a role to play. It could have seriously helped us as a stepping stone to get us from fossil fuel-based generation to renewables. It’s my personal opinion that it’s a bit late for that, and wind and especially solar are very competitive now, from an economic perspective. Having said that, I still see value for nuclear in the future, I just think the bulk of our efforts should be elsewhere.
FYI I worked in the energy sector for over a decade, in market modelling, simulation, optimisation, and control theory, and I helped drive policy and governance, especially as it relates renewable generation.
