High-purity graphene and the age of nanomaterials with Kjirstin Breure

In this episode, Kirsten Brewer, President and CEO of Hydrograph Clean Power, describes graphene as the strongest and most conductive material known. A single atomic layer of carbon atoms, graphene offers unmatched potential for enhancing traditional materials. Unlike most companies that start with graphite, Hydrograph's patented detonation process allows them to produce pristine graphene, significantly improving the quality and consistency of their product, and paving the way for various applications.

Kirsten discusses what she believes to be the onset of a nanotechnology age, highlighting graphene's unique qualities that allow manufacturers to layer functionality onto existing materials. This potential helps avoid the common trade-offs in material properties; for example, increasing strength without compromising ductility. Kirsten envisions bright prospects for manufacturers as they harness graphene in groundbreaking ways, sparking innovations across numerous industries.

The current graphene market is projected to reach $2.5 billion by 2028. Kirsten notes, however, that many companies in the sector struggle with quality issues, with a study revealing a significant discrepancy in actual graphene content versus what is advertised. Hydrograph's commitment to producing high-quality graphene positions them favorably within a market that requires reliable performance.

The episode dives deep into Hydrograph's distinct approach to graphene production. Unlike traditional methods that often result in impurity and inconsistency, their explosive synthesis process involves igniting acetylene in a controlled environment, resulting in high-quality crystals of graphene. This innovative method allows for scalability and consistent output, important factors in sustaining production needs.

Kirsten outlines the various industries benefitting from graphene, particularly composites, coatings, medical devices, and biosensors. Hydrograph is focusing on tangible outcomes and revenue generation by addressing industry pain points and developing applications that can quickly come to market. She expresses excitement about ongoing projects and the potential for graphene in energy storage and advanced materials.

Hydrograph actively collaborates with manufacturers to integrate graphene in their existing and new products. The company has facilities in Manchester that provide access to material expertise and prototyping capabilities. This allows Hydrograph to assist clients effectively in assessing their needs and product development journeys.

Kirsten touches on the regulatory landscape surrounding graphene's use, highlighting that it's largely dependent on the application area and jurisdiction. Hydrograph has applications pending for EPA approval and has noted that graphene, being fundamentally carbon, is inert and has shown no adverse effects under safety studies involving inhalation.
