Airthium

Airthium is developing innovative engine technology with the potential to significantly reduce global CO2 emissions by 33% while remaining cost-competitive. Initially, the company focuses on assisting food and mining companies in lowering both their heating expenses and carbon footprint. This is achieved by replacing traditional gas-fired steam boilers with Airthium's advanced high-temperature heat pumps, which can generate up to three times more heat using the same amount of electricity, even at temperatures reaching 1000°F.

As the heat pump market matures, Airthium plans to expand into seasonal energy storage solutions. These storage units utilize the same proprietary engine technology found in their heat pumps. Designed to integrate with solar and wind energy sources, these units offer a more affordable, sustainable, and dependable alternative to lithium-ion batteries, fossil fuel power plants, carbon capture and storage, and fuel procurement. The flexibility of siting these units anywhere further enhances their appeal.

The initial target market represents a high-margin opportunity responsible for 3% of global CO2 emissions. The subsequent energy storage market presents a substantially larger opportunity, accounting for 30% of worldwide CO2 emissions. This market is expected to grow even further as electric vehicles become more prevalent.

Airthium's core innovation lies in its development of a Stirling engine capable of achieving 86% of the Carnot efficiency, surpassing the current state-of-the-art efficiency of 64%. This is accomplished while simultaneously reducing costs and enhancing reliability.
