The recent Intergovernmental Panel on Climate Change (IPCC) report warned us over the threat global warming is posing, with consequences already being felt and accelerating rapidly. At the same time, the price of oil is at its highest since 2008 and is likely to continue to soar. Although prices at these levels are largely war-driven, both oil and gas prices were already climbing as economies reopened last year. These events have just shown how energy vulnerable and dependent on fossil fuels the global economy still is.

The US Department of Energy's paper, "Grid Operational Impacts of Widespread Storage Deployment" analyzes requirements to 2050. It variously calculates 1.3 TWh required to just over 6.0 TWh in its 94% renewable electricity, Zero Carbon scenario. Earlier, other researchers calculated 80% wind and solar will require 5.4 TWh of energy storage so it is obvious that huge amounts of storage are needed. Even that is with massive over-production and therefore curtailment - electricity only being generated 10% to 20% of the time on average. Polluting peaker plants only have 11% capacity factor so, on that model, bad replaces bad in that respect.

Thursday 10 March 2022 - Saving the planet and reducing local pollution and costs means mainly solar and wind power for the next 20 years with its sudden shut-downs, extended weaknesses and inability to follow demand even when it is working. Major stationary storage will be demanded in three waves.
