Hydrogen Enhanced Fatigue Crack Growth Rates in a Ferritic Fe-3wt%Si Alloy
(Journal article; Peer reviewed, 2018)It is well known that the presence of hydrogen in ferrous materials promotes both static fracture and affect the material fatigue crack growth rates. The latter is often referred to as Hydrogen Enhanced Fatigue Crack Growth ... -
Hydrogen enhanced fatigue crack growth rates in a ferritic Fe-3 wt%Si alloy and a X70 pipeline steel
(Journal article; Peer reviewed, 2019)It is well known that ferrous materials can be damaged by absorption of hydrogen. If a sufficient quantity of hydrogen penetrates into the material, static fracture and the material's fatigue performances can be affected ... -
Hydrogen for maritime application—quality of hydrogen generated onboard ship by electrolysis of purified seawater
(Peer reviewed; Journal article, 2021)Maritime transport is investigating several options to reduce its greenhouse gases and air pollutant emissions. An experimental ship, Energy Observer, is using excess renewable energy to generate onboard hydrogen by ... -
Hydrogen from wet air and sunlight in a tandem photoelectrochemical cell
(Peer reviewed; Journal article, 2019)A solid-state photoelectrochemical (SSPEC) cell is an attractive approach for solar water splitting, especially when it comes to monolithic device design. In a SSPEC cell the electrodes distance is minimized, while the use ... -
Hydrogen Induced Vacancy Clustering and Void Formation Mechanisms at Grain Boundaries in Palladium
(Peer reviewed; Journal article, 2020)Hydrogen has a significant impact on the formation of vacancies, clusters and voids in palladium and other metals. The formation of vacancy-hydrogen complexes in bulk Pd and at Σ3 and Σ5 grain boundaries was investigated ... -
Hydrogen Influence on Mechanical Properties in Pipeline Steel - state of the art
(SINTEF Rapport;, Research report, 2020)The state-of-the-art report consist of an overview and a summary of the mechanical behaviour of pipeline steels (in the range of X42-X70) when exposed to electrochemical charging and gaseous hydrogen environment. Experimental ... -
Hydrogen informed Gurson model for hydrogen embrittlement simulation
(Peer reviewed; Journal article, 2019)Hydrogen-microvoid interactions were studied via unit cell analyses with different hydrogen concentrations. The absolute failure strain decreases with hydrogen concentration, but the failure loci were found to follow the ... -
Hydrogen production by water splitting using gas switching technology
