…This report specifically focuses on the use of supercapacitors in transport and industry. Although more recently, we have been getting excited about supercapacitors as a means of smothing short-term volatility….
…to 20. However, the data are highly variable, as shown by the examples plotted below. Volatility does matter for the costs of integrating renewables, the ultimate share of renewables and…
…volatility issues for later. But eventually, we model that this will result in power grids becoming more expensive and more volatile, which could end up having negative consequences, both for…
…We also tabulate their patent filings. We find most of the offerings will lower end energy demand (by an average of 7%), assist with smoothing grid-volatility, provide appliance-by-appliance demand disaggregations…
…burning down forests and start re-planting them. This does not require electrolysing water molecules into hydrogen, smoothing volatility in renewable-heavy grids, or developing next-generation batteries. It requires something much harder:…
…than hardware (c20%). What surprised us about the patents is that they are mostly focused on smoothing short-term, second-by-second, minute-by-minute volatility caused by increasing renewables deployment (70%). Not moving excess…
…published a primer into energy, a primer into electricity, a primer into power quality, and an overview of renewables volatility. Back-up data follows from technical papers in the final tab….
…a different operating state. Third, there is always a danger that the wind drops at the precise moment you want to implement your frequency response, due to natural wind volatility….
…wind and solar differs however. We see much greater volume growth for solar (in GW pa), combined with much faster future cost deflation (in $/kW), and these two trends balance…
Global energy investment in 2020-21 has been running 10% below the level needed on our roadmap to net zero. Under-investment is steepest for solar, wind and gas. Under-appreciated is that…
