I'm in my mid-50s, and fusion generation has been 10-20 years away all my life.Zhivago wrote:Who says we must limit ourselves to one method of electrical energy generation? The key point is to reduce emissions, especially in our living areas (such as cities). Fossil fuels with carbon capture could be used while we improve efficiency of renewable sources. Onshore wind is cost-effective enough, but indeed some of the other renewable sources need investment and improvement. But we are talking about the future here, I think we can assume progress on that front. I think we can also assume progress on the battery front - Lithium is not the only option, there will be new alternatives that promise more capacity and are more environmentally friendly as we are already starting to see. But we are talking about a 10-20 year vision.Sandydragon wrote:If there is a practical alternative then I'm all for it. But renewables aren't effective enough at the moment. But limiting ourselves to the constraints of wind and solar whilst looking to add to the load is a bad idea.Zhivago wrote:
Power could be generated by renewable energy, or potentially in the longer term even fusion could be possible. Hydrogen on the other hand is primarily produced by steam reformation of hydrocarbon fuels with CO2 as a product.
Point is surely that we should be moving away from using hydrocarbons?? No?
Any alternative has to be practicable for a major economy, no?
I've also worked extensively with batteries for industrial equipment for the last 20 years, and in the last 10 of those there have been incremental improvements in Lithium batteries. There has been a constant stream of articles in the scientific press about the next "replacement" for Lithium, none of which have made the breakthrough to commercial production. I guess, eventually, something that works may crop up, but there is no guarantee, and certainly no guarantee that it will be any less environmentally destructive than Lithium.
