Amongst the many pieces of the puzzle that will make up the UK’s route toward delivering on its net zero ambitions, the way in which we heat our homes is becoming a growing area of concern. Energy used for heating accounts for around 17 per cent of the UK’s carbon emissions, the majority of which […]

Since time immemorial, the British weather has been a cruel joke – the wind, the rain, the general but reliable misery of it all. But could it be, in a world determined (at last) to eradicate carbon from energy production, that the source of misery for so many generations could actually drive an economic boom

The need to decarbonise heat in the UK is increasingly a focus as the country shifts its attention away from pure energy to other highly polluting sectors. Currently the vast majority of home heating is powered by fossil fuels, but this needs to change in order to reach net zero. Heat pumps and hydrogen as

The question of how to decarbonise heat has been rising up the political agenda in the UK since the net-zero target was enshrined in law. Following pressure from organisations including Citizens Advice and the Climate Change Committee, the Heat & Buildings Strategy will be published in the coming weeks, outlining the preferred technology pathway to

UK-based start-up, Caldera, is piloting a cutting edge, domestic heat battery that uses surplus renewable energy on the grid to supply low carbon heat. The battery, named Warmstone, uses patented technology and can be heated overnight using green and inexpensive off-peak electricity. It then operates throughout the day to provide heating and hot water. Read

British start-up Caldera is launching a new large-scale domestic heat battery, capable of providing low carbon heat by utilising excess renewable energy on the grid. The battery is based around its patented technology Warmstone, which can be heated overnight using cheap, green, off-peak electricity. It then discharges heat throughout the day to power heating and

Homes could be kept warm with giant “heat batteries” developed by a British start-up that has won backing from the government and external investors. Caldera, based in Hampshire, uses cheap off-peak power and electrical elements to heat a huge highly-insulated block of material called Warmstone, made from recycled metals and aggregate. A coil of water

A Hampshire-based start-up has launched a new domestic heat battery, which it claims can decarbonise thousands of Scottish homes. Caldera’s Warmstone battery heats up overnight using off-peak electricity and then releases this during the day. The company believes the rollout of its technology in rural areas could provide gigawatts of energy storage from renewable sources

The König Metall Group has taken a stake in the British heating storage provider Caldera, which wants to turn the heating market upside down with its electric ‘heat battery’. The ‘heat battery’ is a 1.5 tonne stone storage tank and is intended to serve as a direct replacement for boilers. Read more at Solarserver (German)

In this episode, James Constable is joined by Baringa’s James Greenleaf, and James Macnaghten from Caldera, as they have a wide-ranging and thought-provoking discussion on the challenges facing the decarbonisation of UK housing stock, the technology solutions available to achieve housing decarbonisation, and the policy and market challenges involved in accelerating the decarbonisation of heat
