Thu-Or17: Hydrogen Liquefaction, Storage and Use 2
- Fridolin Holdener (shirokuma GmbH)
Over the last few years, a number of projects dedicated to the full scale demonstration of cryogenic H2 systems for clean mobility have been successfully carried out at Air Liquide’s Campus Technologies Grenoble (ex-ALaT), in Sassenage (France). Those pioneering prototypes have been designed and operated together with world class industry leaders, and pave the way towards a realistic, cost...
The increased demand for hydrogen as an energy vector and storage medium results in a constantly growing need for higher liquefaction capacity. However, the design of the required ortho-parahydrogen converters is currently subject to major uncertainty. The data on the activity of the current standard catalyst hydrous ferric oxide, commercially available as “Ionex-Type O-P Catalyst” (Ionex) by...
Ortho-para hydrogen catalytic conversion stands as a pivotal process in hydrogen liquefaction. Continuous conversion, the most energy-efficient, is realized by placing catalysts inside channels of heat exchangers. Experimental data is significant to reveal the underlying mechanism of thermal-flow-conversion process and optimize the conversion process, which is still lacking in the accessible...
In the neutron scattering experiments using MW-class pulsed neutron sources, specific pulse shape characteristics, such as high intensity, narrow pulse width and short tail etc., are required. Such pulsed neutrons are typically generated by moderating spallation neutrons using liquid hydrogen. Liquid hydrogen is known as a unique moderator material for the neutrons. However, there are two...
Nowadays, storage of liquid hydrogen (LH2) has become a promising solution to many energy applications compared to conventional fuels. However, self-pressurization phenomenon due to heat leakage into LH2 tanks still represents a bottleneck for its development. Accordingly, accurate prediction of the pressure evolution of LH2 is of great importance and urgent requirement for safe storage,...
At the European Spallation Source (ESS), a 5 MW beam of 2.0 GeV proton with a nominal current of 62.5 mA driven by an accelerator will impact a tungsten wheel target at a repetition rate of 14 Hz and a pulse length of 2.86 ms. The fast neutrons produced via spallation process are reduced to cold and thermal neutrons of lower energy levels by passing through a thermal water pre-moderator and,...
The large-scale storage of liquid hydrogen allows efficient and inexpensive hydrogen energy utilization. Conventional liquid hydrogen storage tanks commonly adopt a high vacuum double-shell spherical configuration, as observed in the tanks used by the National Aeronautics and Space Administration (NASA) and the Port of Kobe. However, this kind of tank faces load distribution challenges,...
Hydrogen is increasingly recognized as an eco-friendly energy source, thanks to its minimal emission of greenhouse gases and pollutants such as CO2 when it reacts with oxygen. Despite this, the challenge of storing hydrogen on a large scale persists due to its low density compared to other materials. Methods such as the use of Ammonia, LOHC (Liquid Organic Hydrogen Carrier), and the...
