Water, PCMs, solid materials or molten salts? What to consider when it comes to thermal energy storage
We’re in the midst of a transition towards low carbon fuels and the electrification of heat, as these options become more accessible. Therefore, the use of heat storage is likely to become more commonplace going forward.
Though not a decarbonisation method in itself, heat storage can be integrated as part of an overall strategy for heat production and delivery.
The starting point for considering heat storage is to understand the profile of the heat demand and heat rejection processes on your site. A strategy can then be developed to use storage where there is benefit from load shifting, integration of renewables or making use of waste heat.
Sounds simple, but it’s important to consider that there are multiple methods of storing heat. Short-term storage solutions can use water, PCMs, solid materials or molten salts. So, how do you decide which one to choose?
In our latest mini guide, we explore how various heat storage solutions work, explaining where each one is most effective and what its main strengths and weaknesses are. It is designed for group and site managers who are tight on time but want to fully understand their options. Set out in a series of helpful graphics and key considerations, it enables you to make informed decisions.
The guide is available in PDF format, and also as a short video presentation.

In the video, Matt Dickinson discusses more readily available options that are suited to industrial sites for short term storage (up to a week). He compares their operating temperatures, explains how they work and provides examples.
Matt is a Principal Consultant on Verco’s Deliver for Zero team. He has over 25 years of experience in manufacturing, building design and energy consultancy, and a strong technical background in the design and operation of energy, heating, and cooling systems.
If you’ve reached a point where you need to upgrade heat infrastructure quickly and don’t have a full decarbonisation roadmap, you’re probably trying to weigh up your options.
Our Low-Carbon Heat Blueprint service typically takes three to four weeks and is just ¼ of the cost of a full decarbonisation roadmap. It will give you the information you need to optimise heat use, generation and distribution, avoid carbon dead ends and make a clear and confident business case.
You’ll get low-carbon heat solution concepts tailored to your site and business goals, a credible project definition, and a robust investment case - everything you need to fast-track effective decarbonisation.
