The 1895 Podcast

Technical debrief: flame detection for hydrogen

In this fifth episode of the Technical Debrief series from The 1895 Podcast, we turn our attention to hydrogen safety and the technologies helping operators detect fires in an evolving energy landscape.
Stephen Harrison speaks with Régis Prévost, of Teledyne Gas and Flame Detection about the latest advances in flame detection technology.
The discussion covers the evolution from traditional UV/IR detectors to triple infrared systems, the challenges of detecting hydrogen and ammonia flames, and how new algorithms are enabling operators to identify fires involving both conventional hydrocarbons and emerging energy carriers.

Technical debrief: solar-powered green hydrogen

In this episode of the Technical Debrief series from The 1895 Podcast, we take a look at a novel approach to solar-powered green hydrogen.
Stephen Harrison speaks with Jan Rongé from Solhyd about the company’s technology, which produces hydrogen directly from solar energy without the need for traditional power conversion systems or liquid water supplies.
They discuss how Solhyd’s modular system connects directly to solar panels, captures water from the atmosphere, and aims to significantly reduce the operating costs of green hydrogen production. The conversation also covers the technology’s flexibility, scalability and potential role in future utility-scale hydrogen projects.

Technical debrief: testing amine degradation products and MOFs for CO2 capture

In this episode of the Technical Debrief series from The 1895 Podcast, we explore the challenges surrounding amine degradation products and the development of next-generation materials for CO2 capture.
Stephen Harrison speaks with Manohara Gudiyor Veerabhadrappa from the National Physical Laboratory (NPL) about the metrology and analytical methods needed to better understand capture technologies and their emissions.
They discuss the risks associated with degradation products from amine-based CO2 capture systems, including the challenge of accurately measuring potentially hazardous compounds. The episode also explores emerging solid-based capture materials such as MOFs and zeolites, their potential advantages in efficiency and scalability, and why more reliable experimental data is needed before large-scale deployment.

Stopping leaks before they start: practical tubing installation lessons from the field

Small-bore tubing failures are rarely caused by bad products but they often start with small installation missteps that lead to leaks, rework, and unplanned downtime. In this episode of The 1895 Podcast we talk with Swagelok Field Engineering expert Joel Martin about the most common installation issues seen across industrial facilities and what teams can do differently to prevent them.
Drawing on real-world field assessments, this conversation breaks down why leaks happen, how to spot early warning signs, and which installation best practices have the biggest impact on system reliability. Topics include proper tubing preparation, correct fitting identification, the risks of mixing components from different manufacturers, and how to safely break and remake connections during commissioning or maintenance.
Whether you’re responsible for installation, maintenance, inspection, or training, this episode offers practical, experience-based guidance to help improve safety, reduce rework, and extend the life of your fluid systems—before problems show up in operation.

Technical debrief: CO2 sampling for midstream in CCS

In this episode of the Technical Debrief from The 1895 Podcast, we continue exploring the technical challenges shaping the future of carbon capture and storage (CCUS), this time focusing on CO2 sampling for midstream CCS applications.
Stephen Harrison of sbh4 speaks once again with Manohara Gudiyor Veerabhadrappa from the National Physical Laboratory (NPL) about the difficulties of accurately measuring CO2 impurities under real-world pipeline conditions.

What's the story: are supply chains pinching?

In this 100th episode of The 1895 Podcast we discuss the growing supply chain risks surrounding helium, rare gases, specialty gases, neon, deuterium, and CO2.
Armed with market sentiment data and industry polling, we cover how geopolitical tensions, supply concentration and semiconductor demand are reshaping confidence across critical gas markets.
Across the podcast, we look at helium market stability and Qatar supply disruption; rare gas vulnerabilities including neon, krypton, and xenon; semiconductor exposure to specialty gas constraints; deuterium supply concerns and emerging demand; and how industrial gas supply chains are adapting to geopolitical risk.
We also reflect on 100 episodes of conversations, picking out our favourite interviews, live event recordings, and breaking industry stories.

Technical debrief: CO2 purity and measurement

In the first episode of the new Technical Debrief series from The 1895 Podcast, we explore one of the most critical, and often overlooked, aspects of carbon capture, utilisation and storage (CCUS) - CO2 purity and measurement.
Stephen Harrison of sbh4 speaks with Manohara Gudiyor Veerabhadrappa from the National Physical Laboratory (NPL) about the challenge of analysing CO2 streams across the CCS value chain.
 

CO2 sourcing and synergies

In this episode of The 1895 Podcast we revisit gasworld's European CO2 Summit 2026 and the Future Sourcing Pathways & Pragmatism panel session.
Joining us for the conversation was, Kripa Balachandran, Head of Product at Mission Zero Technologies; and Sarah Grimm, Business Development Manager at Reverion.
In the session, we covered future CO2 sourcing pathways, the role of direct air capture (DAC), biogenic CO2, and the challenges and opportunities facing the CO2 market amidst geopolitical and regulatory developments. 

CO2 markets, fragilities and improvements

In this episode of The 1895 Podcast, we reflect on gasworld's European CO2 Summit 2026, listening back from some of our speakers key takeaways from the conference. 
We hear insight from Aidan Sparrowhawk, of GWGI; Gabriel Kiewek, of Nippon Sanso; Pablo Molina, of the European Biogas Association; and Stephen Harrison, of shb4 as they discus CO2 markets, feedstock and the low hanging fruit for low-cost sourcing.

Update on the state-of-play in the Middle East

In this episode of The 1895 Podcast, we provide an update on the conflict in the Middle East, the ceasefire, its implications on global energy markets, and the impact on supply chains.
We also look at the supply risks for bromine and deuterium, and the danger it creates for the chip industry.
