Four national institutions have failed to model the 2050 energy system correctly, and all of them in ways that lead to understatement of the costs of Net Zero.
Over the weekend, the Sunday Telegraph reported that the Climate Change Committee has got its energy system modelling wrong. The revelation was made by Sir Christopher Llewellyn Smith, the lead author of the recent Royal Society report on electricity storage, in remarks made at a seminar at Oxford.
According to Sir Christopher, the Climate Change Committee’s estimates of the costs of Net Zero are fundamentally flawed because they have only modelled isolated years. As he pointed out in the seminar, low-wind years can happen back to back, which means that the Climate Change Committee need twice as much storage capacity as they thought. As a result, they have underestimated the costs.
