So this myth is what you need to tell yourself we need nuclear?
- UltraSane 6mo agoWhat else would we use for backup when wind and solar aren't producing enough power? Gas, coal, and nuclear are the only real options.
- amanaplanacanal 6mo agoAre you pretending batteries don't exist? And long distance interconnects? And not even talking about hydro, geothermal, wave, and who knows what else.
- UltraSane 6mo agogrid scale batteries longer than 4 hours don't exist. You can't design a reliable electrical grid based on vibes. You have to design it on what cost effective technologies actually exist where you need them.
- amanaplanacanal 6mo agoOf course! Are you a grid designer? What does your model of solar and wind look like for your location?
- UltraSane 6mo agoI'm just a reasonably intelligent person who understands thermodynamics and can quantify electricity production and consumption.
- tcfhgj 6mo agoId say this is plainly wrong. Additionally, there are more storage technologies than batteries in the classical sense.
- UltraSane 6mo agoThe only other grid scale tech I'm aware of is pumped hydro which is very effective BUT severely limited to areas with existing good topography where you have two large enough basins separated by substantial height.
- tcfhgj 6mo agowell, there are batteries of all kinds, there is green gas, and many other systems which can in one way or another support the grid - each with their respective advantages and disadvantages, such as capacity, controllability, cost, space requirements, topography requirements, ...
- UltraSane 6mo agoALL BES currently installed have 4 hour capacity or less. It is far too expensive to have multiple day grid scale BES. I'm so tired of having to repeat this basic fact. WTF is green gas?
