On this week's show we speak with Trevor Best CEO of Syzygy Plasmonics a Houston area startup who is a pioneer in the field of photocatalytic based hydrogen production. The company has recently closed its series A funding round. We discuss with Trevor the potential applications of the Syzygy approach and where they are aiming to engage the market first as well as his view of the evolution of the hydrogen market today. All this and more on the show!

Austenitic stainless steels are used for hydrogen containment of high-pressure hydrogen gas due to their ability to retain high fracture properties despite the degradation due to hydrogen. Forging and other strain-hardening processes are desirable for austenitic stainless steels to increase the material strength and thus accommodate higher stresses and reduce material costs. Welding is often necessary for assembling components but it represents an area of concern in pressure containment structures due to the potential for defects more environmentally susceptible microstructure and reduced strength. Electron beam (EB) welding represent an advanced joining process which has advantages over traditional arc welding techniques through reduced input heat and reduced heat-affected zone (HAZ) microstructure and thus present a means to maintain high strength and improve weld performance in hydrogen gas containment. In this study fracture coupons were extracted from EB welds in forged 304L and subjected to thermal gaseous hydrogen precharging at select pressures to introduce different levels of internal hydrogen content. Fracture tests were then performed on hydrogen precharged coupons at temperatures of both 293 K and 223 K. It was observed that fracture resistance (JH) was dependent on internal hydrogen concentration; higher hydrogen concentrations resulted in lower fracture resistance in both the forged 304L base material and the 304L EB welds. This trend was also apparent at both temperatures: 293 K and 223 K. EB weld samples however maintain high fracture resistance comparable to the forged 304L base material. The role of weld microstructure solidification on fracture is discussed.

Today we are joined by our good friends from Enapter. The company is a leader in the clean hydrogen sector focused on AEM electrolyzer technology and innovative software solutions that make it possible to rapidly deploy and scale hydrogen production assets. For those who follow the hydrogen sector regularly it’s been hard not to hear Enapter-related news in 2021 and its impressive trajectory as they have gone public announced the plans for a brand new production facility in Germany (on which they have now begun construction) and most recently the announcement that Enapter was selected as the winner of the prestigious Earthshot prize. To do that we are absolutely delighted to have with us all the way from his home base in Thailand Thomas Chrometzka Chief Strategy Officer at Enapter and one of the people that we enjoy having on the show so much that we have brought him back again to fill us in on what he and Enapter are up to and what they have planned for the future of hydrogen.

Chris Jackson is the Founder and CEO of Protium Green Solutions based in London. Protium is a hydrogen energy services company that designs develops finances owns and operates clean hydrogen solutions for clients to achieve net zero energy emissions at their industrial/manufacturing sites. Chris will talk to us about the Protium story and also give us some insight into a major project that Protium recently announced in conjunction Budweiser Brewing Group UK&Ireland to explore the deployment of zero emission green hydrogen at Magor brewery in South Wales one of the largest breweries in the UK. To that end in order to get the full story about this project we are delighted to say that we have yet another great guest on this episode. Tom Brewer who leads Global Environmental Sustainability efforts at AB InBev the parent company of Budweiser Brewing Group will join us for the final segment of the show to talk about how hydrogen fits into AB InBev’s vision of a sustainable future for the company.

We have been talking about the difficulties of decarbonizing the maritime sector since the beginning of the Everything About Hydrogen podcast. For this episode we finally bring on the experts who are looking to make the changes in maritime and marine operations a reality for a zero-carbon shipping future. The EAH Team sits down with Tomas Tronstad Head of Shipping and Technology for the New Energy Division at Wilhelmsen Group. Founded in Norway in 1861 Wilhelmsen is now a comprehensive global maritime group providing essential products and services to the merchant fleet along with supplying crew and technical management to the largest and most complex vessels ever to sail. Committed to shaping the maritime industry the company also seeks to develop new opportunities and collaborations in renewables zero-emission shipping and marine digitalization. Tomas is helping Wilhelmsen achieve its decarbonization ambitions and we are delighted to share our conversation with him with our listerners!

On this weeks episode the team are talking all things hydrogen with Mark Neller Director at Arup. On the show we discuss the UK’s Hydrogen4Heat program where Arup has been leading the UK government’s work on the safety and practical considerations that are necessary to examine whether hydrogen could be a serious solutions for decarbonising UK residential commercial and industry heat. We also discuss the Nikola Badger the need for system wide planning when considering decarbonisation pathways for heat. All this and more on the show!

On this week's episode the EAH team catches up with Mark Selby Chief Technology Officer at Ceres Power to dive into the world of solid oxide fuel cell (SOFC) and solid oxide electrolyzer (SOE) technologies. Ceres Power specializes in the design of SOFCs for applications in a diverse range of energy intensive sectors. Mark takes the time in this episode to walk the team through the details advantages and challenges of deploying SOFCs and low-carbon hydrogen solutions more broadly and discusses how consumer and customer awareness of these technologies varies widely across international markets. We cover a lot of ground this week so be sure not to miss out on our conversation with Mark!

How do we get green hydrogen (and green ammonia) production to scale and make it cost competitive? It's a great question and we ask it all the time on the show. Well Alicia Eastman Co-founder & Managing Director of InterContinental Energy (ICE) may be one of the best authorities in the world on this topic and she joins us on this episode of EAH to tell the team all about her and ICE's work developing the Asian Renewable Energy Hub (AREH). Located in Western Australia the AREH when completed will be the largest renewable energy project by total generation capacity on the planet. At 26 GW it surpasses even the likes of the Three Gorges Dam and will act as a central production and distribution point for huge quantities of clean hydrogen and ammonia for offtakers and customers across APAC and beyond. The AREH is a truly massive project that has global implications for the global energy landscape of the future.

With more renewables on the Swedish electricity market while decommissioning nuclear power plants electricity supply increasingly fluctuates and electricity prices are more volatile. There is hence a need for securing the electricity supply before energy storage solutions become widespread. Electricity price fluctuations moreover affect operating income of nuclear power plants due to their inherent operational inflexibility. Since the anticipated new applications of hydrogen in fuel cell vehicles and steel production producing hydrogen has become a potential source of income particularly when there is a surplus supply of electricity at low prices. The feasibility of investing in hydrogen production was investigated in a nuclear power plant applying Swedish energy policy as background. The analysis applies a system dynamics approach incorporating the stochastic feature of electricity supply and prices. The study revealed that hydrogen production brings alternative opportunities for large-scale electricity production facilities in Sweden. Factors such as hydrogen price will be influential and require in-depth investigation. This study provides guidelines for power sector policymakers and managers who plan to engage in hydrogen production for industrial applications. Although this study was focused upon nuclear power sources it can be extended to hydrogen production from renewable energy sources such as wind and solar.
