The power system challenge for the new UK government

One early task for the upcoming new UK government will be to oversee, along with the National Energy System Operator, development of the electricity grid necessary to support progress towards net zero. Here, Simon Skillings, Senior Associate at climate change think tank E3G, proposes a ‘Power System Delivery Office’ to take on the task.

Smart heat pumps: the potential for demand flexibility in the home

We are partly through a journey into widespread acceptance of the efficacy and suitability of heat pumps to serve UK homes. But a new study has demonstrated another valuable set of advantages to operators of electricity networks that should tip the balance decisively, argues Professor Patrick James from the University of Southampton.

Turning UK business’ rooftops into strategic energy assets

The roofs of commercial and industrial sector buildings remain underused as sites of new, decentralised solar power stations. But such systems could deliver serious business advantages to the building occupiers. Owen Power, CEO of renewable energy developer Greenvolt UK, makes the case for installing them.

How solar thermal storage can decarbonise industrial heat

While the growth of solar power for electricity generation has been spectacular, the use of solar-generated power to produce and store heat for industrial users is at a much earlier stage. But the technology and potential is there, writes James Macnaghten, CEO of the UK-based energy storage supplier Caldera.

Project profile: MESH, potentially the UK’s largest long-duration energy store

The MESH energy storage project is being developed by EnergyPathways in salt caverns beneath the East Irish Sea, with onshore facilities at the Port of Barrow, Cumbria. At 300MW and 55GWh capacity, with more than 100 hours of discharge at full power, MESH is set to be the UK’s largest long-duration energy storage (LDES) facility, writes Ben Clube, EnergyPathways’ Chief Executive Officer.

Powering the future: the need for smarter grid connections for EV charging

As the UK decarbonises its transport network, it shifts the source of energy for vehicle propulsion from fossil fuel supply chains to the electricity grid. But the grid is also experiencing high levels of demand for electrified heating and, increasingly, for power for data centres. This is why we should consider stations with batteries and on-site power generation at scale for rolling out electric vehicle (EV) charging, contends Delvin Lane, Chief Executive Officer of EV charging developer InstaVolt.
