Market Overview
Aerogels are highly porous, solid materials derived from a gel, where the liquid component is replaced by gas without collapsing the gel structure. This unique characteristic results in ultralight materials with extremely low thermal conductivity, making aerogels ideal for insulation and protective purposes.
According to the research report published by Polaris Market Research, the global aerogel market was valued at USD 835.16 million in 2021 and is expected to reach USD 2,656.20 million by 2030, to grow at a CAGR of 14.9% during the forecast period.
Key Market Growth Drivers
- Growing Demand for Thermal Insulation Materials
The increasing global focus on energy conservation and reducing greenhouse gas emissions has significantly increased the demand for high-performance insulation materials. Aerogels, with their low thermal conductivity (as low as 0.013 W/m·K), outperform traditional materials such as fiberglass, mineral wool, and polyurethane foams.
This has led to their widespread adoption in industrial insulation, particularly in sectors like oil & gas, where pipeline insulation is critical, and building construction, where green building standards require materials with superior thermal efficiency.
- Rising Adoption in Aerospace and Defense
The aerospace sector is increasingly integrating lightweight aerogel insulation materials into spacecraft, satellites, and aircraft to reduce weight and improve fuel efficiency. NASA has been using aerogels for years in space missions, notably in the Stardust mission for capturing comet particles.
Aerogels’ ability to withstand extreme temperatures and radiation makes them ideal for thermal insulation blankets, crew cabin protection, and soundproofing materials in aerospace and defense systems. As the aerospace industry expands, so does the market for advanced insulation materials.
- Expanding Applications in Electric Vehicles and Batteries
As the global automotive industry shifts toward electrification, aerogels are being increasingly considered for battery thermal management, lightweight panels, and EV component protection. Their excellent fire resistance and thermal stability are crucial in improving the safety and efficiency of electric vehicles.
Moreover, carbon aerogels are gaining popularity as supercapacitor electrode materials due to their high surface area and electrical conductivity, helping improve the energy density of storage systems in EVs and renewable energy grids.
- Sustainability and Green Building Regulations
Global movements toward sustainable development and carbon neutrality are boosting demand for green construction materials. Aerogels, especially those derived from eco-friendly precursors, align well with LEED-certified building practices.
Their integration into insulating panels, roofing systems, and window glazing not only improves energy efficiency but also contributes to long-term cost savings in commercial and residential buildings. Governments and regulatory bodies are increasingly mandating higher insulation standards, further promoting aerogel adoption.

Market Challenges
- High Production Costs
One of the major limitations hindering widespread commercial use of aerogels is their high manufacturing cost. Producing aerogels involves energy-intensive and time-consuming processes, such as supercritical drying, which elevate the overall product cost.
Although research into ambient pressure drying and sol-gel chemistry improvements is ongoing, cost reduction remains a top priority to ensure broader accessibility in price-sensitive industries like consumer electronics and mass-market construction.
- Brittleness and Structural Limitations
Traditional silica aerogels are notoriously fragile and brittle, making them difficult to handle and limiting their use in applications that require mechanical robustness. Although advancements like reinforced composite aerogels and polymer-based aerogels have improved durability, the challenge of mechanical integrity continues to impede certain industrial applications.
- Limited Awareness and Commercial Scale
Despite their advantages, aerogels remain underutilized due to limited awareness among end-users and lack of commercial-scale suppliers. Many industries still rely on conventional materials, either due to habit, lack of familiarity with aerogel properties, or due to integration challenges in existing systems.
Educating industries on long-term cost benefits, performance advantages, and environmental impact is essential to improving aerogel market penetration.
