This study reviews the extant literature on hydrogen production cost forecasts to identify and analyze the historical trend of such forecasts in order to explore the feasibility of wider adoption. Hydrogen is an important energy source that can be used to achieve a carbon-neutral society but the widespread adoption of hydrogen production technologies is hampered by the high costs. The production costs vary depending on the technology employed: gray rene Read More

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 Read More

The simultaneous photocatalytic H2 evolution with environmental remediation over semiconducting metal oxides is a fascinating process for sustainable fuel production. However most of the previously reported photocatalytic reforming showed nonstoichiometric amounts of the evolved H2 when organic substrates were used. To explain the reasons for this phenomenon a careful analysis of the products and intermediates in gas and aqueous phases upon the Read More

On this week's episode of Everything About Hydrogen the team are celebrating the show's one year anniversary with Randy MacEwen the CEO of Ballard Power Systems. On the show the team ask Randy to explain the stunning rise of hydrogen over the last 12-24 months how the use cases for hydrogen are evolving and how the growing capitalisation of listed businesses like Ballard is driving a change in the investor base across the hydrogen & fuel cell Read More

Predicting lower flammability limits (LFL) of hydrogen has become an ever-important task for safety of nuclear industry. While numerous experimental studies have been conducted LFL results applicable for the harsh environment are still lack of information. Our aim is to develop a calculated non-adiabatic flame temperature (CNAFT) model to better predict LFL of hydrogen mixtures in nuclear power plant. The developed model is unique for incorporating r Read More

For our 40th episode of the Everything About Hydrogen podcast the gang are joined by hydrogen luminary Marco Alverà the CEO of Snam. Founded in 1941 and listed on the Italian stock exchange since 2001 Snam is a leader in the European gas market and operator of over 41000km of transport networks. Hailed as a visionary who has led the pivot of the world’s 2nd largest gas distribution company towards a clean gas trajectory Marco is widely recognized Read More

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 Read More

This Supplement gives additional requirements and qualifications for the transmission of Hydrogen including Natural Gas/Hydrogen blended mixtures (subsequently referred to as NG/H blends) and for the repurposing of Natural Gas (NG) pipelines to Hydrogen service. For the purposes of this document any NG/H blend above 10% MOL is considered to be an equivalence to 100% hydrogen. For blends below 10% MOL there is no evidence to confirm tha Read More

Steam methane reforming with CO2 capture (blue hydrogen) and water electrolysis based on renewable electricity (green hydrogen) are commonly assumed to be the main supply options in a future hydrogen economy. However another promising method is emerging in the form of natural gas pyrolysis (turquoise hydrogen) with pure carbon as a valuable by-product. To better understand the potential of turquoise hydrogen this study presents a techno-econ Read More

Decentralisation and sector coupling are becoming increasingly crucial for the decarbonisation of the energy system. Resources such as waste and water have high energy recovery potential and are required as inputs for various conversion technologies; however waste and water have not yet been considered in sector coupling approaches but only in separate examinations. In this work an open-source sector coupling optimisation model considering all o Read More
