Electricity storage on the fly

Last week saw the news that the UK is to host Europe’s largest battery flywheel energy storage system, which will provide fast frequency response services to both the GB and Irish markets. The £3.5 million project will be delivered by a a consortium of engineers from the University of Sheffield, flywheel specialists Schwungrad Energie and…

Finding the right business model for electricity storage

The question of how electricity storage should be treated by regulators is once again in the news, with National Grid and UK Power Networks making submissions to the UK Government setting out their reasons for wanting to be able to own and operate electricity storage assets themselves. They argue that as storage can be used as an alternative…

Solar + Storage: the other side of the story

In this second post on the viability of solar + storage (first post here) I examine the conclusions of the Aurora Energy report, which presents a rather more optimistic view of the prospects of the combined technologies, claiming that the cost of backing up solar generation and integrating it into the energy system was negligible,…

Shining a light on solar + storage

Solar + storage, the combination of solar power and electricity storage, is seen by many as the Holy Grail of the energy markets and the key to a secure, low carbon future. However two recent reports provide conflicting views on whether this is a realistic prospect or simply another myth. In its analysis, the Adam Smith Institute…

Breaking the ice with thermal energy storage

In the second article in my series on energy storage, I explore the area of thermal energy storage (TES), which involves the collection of excess thermal energy for later use. This and can be achieved through a range of technologies, at an individual building, district or even regional scale. The technologies fall into three broad…

CCS: is it all just hot air?

  Last week I attended an Energy Institute debate on the subject “Meeting the Carbon Budgets – how “disruptive” technologies could be game changers towards a low carbon future.” The eminent speakers gave an overview of the challenges arising from the Paris agreement in 2015 and focused specifically on large-scale nuclear versus small modular reactors…

CAES…an alternative to pumped hydro?

Energy storage is seen by some as the Holy Grail of the energy markets, providing a low-carbon alternative to conventional generation for balancing systems with increasing levels of intermittent renewable generation. Over a series of posts, I will explore some of the technologies under development and assess the relative strengths and weaknesses of the various…

Driving storage innovation

Domestic solar + electricity storage has for some time been seen as a potentially disruptive combination for electricity systems. Add in electric cars and use of recycled EV batteries in those storage systems, and the story becomes even more interesting. Car companies expanding into energy storage have been all over the news recently. Electric vehicles…
