    From Cambridge to Seoul: TeraView's IPO in South Korea

    In this latest episode of Talks with Turquoise, we explore how UK deeptech is rethinking the traditional IPO playbook. Low Carbon Innovation Fund 2 business, TeraView, a leader in terahertz imaging and spectroscopy, has taken an unconventional route by listing on South Korea’s KOSDAQ - a growth-focused market often likened to Nasdaq, with a strong appetite for advanced technology companies. The move reflects a broader shift among British scale-ups seeking global capital, valuation alignment and investors who understand complex innovation.   We discuss why KOSDAQ proved an attractive platform, what the listing means for the future of UK science-led businesses, and whether overseas IPOs could become a viable alternative for ambitious companies looking to scale.   Joining the conversation is Ian Thomas, Managing Director at Turquoise and TeraView CEO Dr. Don Arnone.   Arnone shares insight into the evolving global capital markets landscape and what TeraView’s successful listing (opening at 8,000 won and reaching a high of 15,500 won) signals for investor confidence in terahertz technology and deeptech innovation. Ian and Don discuss:   TeraView’s technology and growing momentum: How terahertz imaging and spectroscopy unlock visibility beyond optical and X-ray systems, and why this capability is gaining traction across semiconductors, batteries and future 6G applicationsThe company’s IPO performance and growth back storyWhy KOSDAQ made strategic senseWider implications for UK scale-ups - what this move signals for other UK science-led companies weighing global listings, and whether overseas markets increasingly offer a clearer route to scale than staying domestic This episode was recorded on 15 January 2026.

    Scaling clean energy storage with RheEnergise

    In the latest episode of Talks with Turquoise, we shine a light on a breakthrough in long-duration energy storage that could transform how we balance renewable power. Turquoise Managing Director Ian Thomas sits down with Stephen Crosher, CEO of RheEnergise, to explore how the company’s High-Density Hydro® (HD Hydro®) technology is reimagining the world’s dominant form of storage - pumped hydro. Instead of relying on vast mountain ranges, RheEnergise’s solution uses a proprietary HD Fluid R-19, which is 2.5x denser than water, environmentally benign, and safe. This innovation delivers 2.5x the power and energy of traditional pumped hydro - unlocking thousands of new project sites across smaller hills and landscapes. With project sizes ranging from 10MW to 100MW, HD Hydro® offers a scalable, low-cost, and low-impact path to storing renewable energy at scale. RheEnergise’s technology is fast to deploy, adaptable to local geographies, and positioned to play a central role in delivering reliable, net-zero power systems worldwide.
