Real Tech Fund, managed by Real Tech Holdings Corporation (Location: Sumida-ku, Tokyo; Representatives: Yukihiro Maru and Akihiko Nagata), has invested into Nano Frontier Technology Inc. NFT will use the funds raised to develop businesses in collaboration with solar thermal power plants, with the aim of decarbonizing the world through the widespread use of solar thermal power generation.

■Company Profile

 NFT is a company that develops coatings using ultrafine atomization technology to  maximize the performance of nanomaterials under the mission to “leverage the use of ultrafine atomization technology for the next society”.

 Heat collection coatings for solar thermal power plants reach temperatures of over 600 degrees Celsius, necessitating high coating durability. Existing paints need to be reapplied once or twice a year, incurring significant loss costs when operations are shut down each time.

 In contrast, NFT coatings have proven long-term heat resistance and need to be reapplied only once every few years.

■Purpose and Use of Funding

 Through demonstration tests with major solar thermal power plants in Australia and China, we aim to deploy NFT paints and coatings worldwide. NFT is working on the use of drones as a maintenance application for receivers (solar thermal collectors) located at high altitudes.

Comment from Real Tech Fund’s Growth Manager

Currently, Pyromark dominates the market for solar thermal collector coatings, and there are many areas for improvement in order to promote the spread of solar thermal power plants. In this context, I believe that NFT has the potential to lead a decarbonized society by possessing technologies that maximize the inherent potential of materials. The founder, Ms. Tsuda, is also a true scientist who decided to start a deep tech venture with no academic experience as a scientist, and I am honored to be supporting scientists and engineers who are striving to make technology the power of the future.
