Although there is a lot of potential for the technology on the long term basis, the market still experiences problems related to the stage of early commercialization of sand battery technology. There are not many large-scale installations, and as a result, there is little experience in operations and conservative decision making from utilities and industrial consumers. Moreover, the developers have to combine the thermal storage with the existing heat networks, renewable sources of energy and industries, which implies that specific engineering solutions are needed that raise the price of implementation and increase project duration. There is also a lack of standardized technical standards for various thermal storage technologies, which makes it difficult to predict the returns on investment.

Opportunities: Decarburization of industry and development of district heating systems.

Increasing initiatives worldwide to cut down carbon footprint in industrial operations have resulted in ample opportunities for the sand battery concept. Industries which consume large quantities of energy need heat of moderate or high temperature, which till now relied heavily on fossil fuels, thus presenting a good prospect for decarburization through energy storage. At the same time, district heating systems based on renewable energy and waste heat recovery technologies are being developed by governments to increase efficiency and cut down greenhouse gas emissions. The sand batteries are capable of storing thermal energy for several days, if not weeks, thus ensuring the availability of heat in case of non-availability of renewable sources of energy.
