The Ultra-LDES Challenge The UK Government has launched the £28 million Ultra-Long Duration Energy Storage Challenge. The goal is to develop technologies capable of storing clean wind and solar energy for 100 hours or more (at least four days). This initiative aims to eradicate the UK's reliance on expensive gas-fired generation during "dunkelflaute" periods (no wind, no sun). For domestic retrofits, this grid-level evolution completely shifts how we plan home solar array sizing, domestic battery capacity, and smart energy tariffs. The 100-hour horizon: decarbonising the gaps The official government announcement of the Challenge marks a pivotal moment in the UK's transition…

The Enterprise Centre at the University of East Anglia (UEA) The UK built environment is at a critical turning point For decades, the construction industry focused almost entirely on operational carbon - the energy used to heat, light, and power a building once occupied. However, as the UK grid decarbonises and heat pumps replace gas boilers, the focus must shift. Today, the immediate threat comes from upfront carbon, which is the greenhouse gas footprint generated before a property is even handed over to the occupier. For PRL, property owners, developers, and other retrofit professionals, tackling this initial carbon spike is…
