The growth in the historic period can be attributed to increasing awareness of the environmental impacts, the need for reliable and durable cooling solutions, the rise in the adoption of electric vehicles, the rapid growth of consumer electronics, and the rise of industrial automation.

The solid state cooling market size is expected to see rapid growth in the next few years. It will grow to $1.29 billion in 2029 at a compound annual growth rate (CAGR) of 11.9%. The growth in the forecast period can be attributed to increasing investment in research and development, expansion of data centers, stricter regulations on energy consumption, increasing use of thermoelectric coolers, and rising demand for advanced cooling solutions in the military and aerospace sectors. Major trends in the forecast period include advancements in thermoelectric materials, developments in materials science, advancements in semiconductor technology, development of electric and hybrid vehicles and enhanced reliability and lifespan of solid-state cooling devices.

The increasing demand for electric vehicles (EVs) is expected to drive the growth of the solid-state cooling market moving forward. Electric vehicles are powered by electric motors and batteries instead of traditional internal combustion engines. This shift in demand is driven by factors such as improved environmental sustainability, lower operational costs, government incentives, advancements in battery technology, and the expansion of charging infrastructure. Solid-state cooling technology in electric vehicles provides efficient thermal management without the use of conventional refrigerants. This enhances battery life and performance through compact and reliable cooling solutions. For example, a report from the International Energy Agency in October 2023 highlighted significant global sales figures, including approximately 66,000 electric buses and 60,000 medium- and heavy-duty trucks sold in 2022, which represented about 4.5% and 1.2% of total sales respectively. In China alone, the market share of electric trucks rose from 1.5% in 2021 to 3.9% in 2022, demonstrating rapid growth within a single year. Consequently, the expanding adoption of electric vehicles is a key driver behind the growth of the solid-state cooling market, driven by the need for efficient thermal management solutions that support the performance and longevity of EV batteries.

Major companies in the solid-state cooling market are focusing on advancing their product offerings, such as micro-multistage thermoelectric coolers (micro TECs), to enhance cooling efficiency and expand the applications of solid-state cooling technology. Micro-multistage thermoelectric coolers are devices that integrate multiple single-stage thermoelectric coolers in series, enabling them to achieve lower temperatures compared to single-stage devices. For example, in June 2023, Laird Thermal Systems, a US-based developer and manufacturer specializing in thermoelectric coolers, launched the OptoTEC MSX Series. This series of micro-multistage thermoelectric coolers is designed to be integrated into various optical packages such as TO-39, TO-46, or TO-8, creating advanced optical thermoelectric assemblies (TEAs). The OptoTEC MSX Series utilizes advanced ceramic materials, proprietary solder bonding techniques, and next-generation thermoelectric materials to increase cooling capacity by up to 10%, all within a compact micro footprint. Optical TEAs are specifically tailored for high-performance image sensing applications and are extensively used in analytical, industrial, and aerospace sectors. This innovation underscores Laird Thermal Systems' commitment to pushing the boundaries of solid-state cooling technology to meet the demanding requirements of modern industries.

Solid-state cooling is an innovative technology that utilizes solid-state materials, typically semiconductors, to achieve cooling effects without relying on traditional refrigerants, compressors, or moving parts found in conventional refrigeration systems. This technology exploits the Peltier effect, where an electric current passing through two different conductive materials (joined at two junctions) generates a temperature difference between these junctions, enabling heat transfer.

The primary types of solid-state cooling include single-stage, multi-stage, and thermocyclers. Single-stage systems are the most prevalent, featuring a single thermoelectric module that moves heat from one side to the other when an electric current is applied. This technology encompasses various methods such as thermoelectric cooling, electro-caloric cooling, and magneto-caloric cooling. It finds applications across diverse products including refrigeration systems, refrigerators, freezers, cooling systems, air conditioners, and chillers. Solid-state cooling serves a wide range of industries including medical, automotive, consumer electronics, semiconductors, and others, offering efficient and compact cooling solutions with potential benefits in energy efficiency and environmental sustainability.
