Green hydrogen has significant potential as an energy
storage medium and as a clean energy carrier in many hard to
decarbonize sectors. There is significant ongoing research on
coupling offshore wind with hydrogen production via
electrolysis. For large offshore wind farms, located further from
shore, transporting energy onshore via hydrogen pipeline can be
a more cost-effective solution in comparison to electrical
alternatives. This research investigates how the intermittent
nature of an offshore wind resource impacts the components of
an offshore wind-to-hydrogen system. A variable supply of power
from an intermittent offshore wind resource can impact
electrolyser performance. Proton exchange membrane
electrolysers are frequently identified as being the most suited to
offshore hydrogen production, due to their wide operating range
and fast starting speed. However, electroyser degradation will
occur if no current is applied during no wind periods. Variable
hydrogen production from an intermittent offshore wind resource
can cause a fluctuating flow of hydrogen gas in the pipeline. The
resulting pressure variations can cause pipeline fatigue and
increase the likelihood of hydrogen embrittlement. A
configuration using battery and hydrogen storage is proposed to
mitigate these impacts, for hydrogen production on a centralized
offshore platform from floating offshore wind

α-Allylation of α-amino acids via 1,5-hydrogen atom transfer
Chowdhry, MI; Horton, PN; Hursthouse, MB; et al. (Elsevier, 2009)A straightforward method for the radical-based α-allylation of proteinogenic α-amino acids is described in which the key step involves 1,5-hydrogen atom transfer from the C-4 position of an oxazolidin-5-one. -
The effect of hydrogen sulfide donors on lipopolysaccharide-induced formation of inflammatory mediators in macrophages.
Li, L; Rose, P; Tan, CH; et al. (Mary Ann Liebert, 15 May 2010)The role of hydrogen sulfide (H(2)S) in inflammation is controversial, with both pro- and antiinflammatory effects documented. Many studies have used simple sulfide salts as the source of H(2)S, which give a rapid bolus ... -
The two-dimensional hydrogen atom revisited
Parfitt, D.G.W.; Portnoi, M.E. (American Institute of Physics, 2002)The bound-state energy eigenvalues for the two-dimensional Kepler problem are found to be degenerate. This “accidental” degeneracy is due to the existence of a two-dimensional analog of the quantum-mechanical Runge–Lenz ...
