During the first 18 months, H2OCEAN has completed
a varied set of objectives and results. The
stakeholder requirements for an H2OCEAN system
have been identified and analysed, including
design constraints and system boundaries
and interfaces. Based on this, three sites have
been selected (North Atlantic Ocean, North Sea
and Mediterranean Sea) to develop and test
an H2OCEAN design. An outline design specification
for the H2OCEAN concept has been
produced in the form of a 'Technical dimension
paper', specifying key parameters (electrical
output, fresh water, hydrogen and oxygen,
aquaculture farm) and a glossary of terms. An
aerodynamic modelling of a floating Verticalaxis
wind turbines (VAWT), considering unsteady
wind profiles and platform motions has been
developed (incl. hydrodynamic, gyroscopic, inertia
and mooring), and individual modules have
been validated with data. Based on the P80
WEC (Wave Energy Converter), an integrated | WEC+VAWT hydrodynamic model has been built
and design sensitivities have been conducted
for a range of VAWT parameters. Regarding
hydrogen generation, electrolysis technologies
have been evaluated with the requirements of
an H2OCEAN design and a low pressure alkaline
electrolyser has been selected. A preliminary
design of the offshore desalination system
has been completed as well. Regarding
aquaculture, the specific combination of species
to be cultured at each site (fish, shellfish and
seaweeds) has been defined, full production
programmes have developed and transportation
requirements analysed and determined.
A broad environmental impact scoping study for
the three sites has been produced (European
directives, baseline conditions/impacts, potential
impact factors, broad identification of stakeholders,
recommendations for the Environmental
Impact Assessment, etc). A pilot version of the
software tool to evaluate H2OCEAN optimal |
