TECHNICAL INNOVATIONS
Hi-Float platforms can be used as energy
clusters that will turn oceans into new spaces for
sustainable energy production, HD Hyundai says.
POSITIONED FOR
PRODUCTIVITY.
small and mid-sized ships will feature electric propulsion.
" Electric vessels are great not just for their carbon-reduction advantages,
but also for more responsive control, greater flexibility
in system design, low noise and low vibration, " he said. " We'll be
able to use [our] Solid Oxide Fuel Cell (SOFC) with hydrogen to
power our ships much more efficiently and sustainably. "
The company also touted its range of wind-assisted propulsion
systems such as Hi-Rotor, HD Hyundai's rotor sail solution,
as well as wing sail. " They maximize the aerodynamic
forces to improve your ship's fuel efficiency by as much as
20-30% if the wind's right, " Kim said. " We're also developing
the world's first LNG carrier with its aerodynamically shaped
superstructure in front of the ship. This design can reduce
wind resistance by almost 30%. "
Kim continued, " These hydrogen charging stations will
supply our lineup of carbon-free construction equipment like
hydrogen-powered excavators and forklifts, as well as a fastgrowing
range of hydrogen cars and machines. We're also
developing our first-generation SOFCs together with the
Fraunhofer Institute in Germany which convert hydrogen to
generate energy. Our goal is to deliver SOFC with a total
efficiency of 85% by 2025 - that's double the fuel efficiency
of conventional fossil-fuel engines. "
Team turbine
HD Hyundai has several partners in the production of clean
energy. One of them is General Electric, which has gotten
onboard with the company's offshore wind power facilities.
Jan Kjaersgaard, CEO of GE offshore wind, described the advantages
of offshore wind generation. " The Hi-Float platforms
can float energy production facilities anywhere regardless of
depth or topography, and maintain stability even in harsh
weather thanks to its center turbine design, " he said.
Kjaersgaard continued saying, " Offshore windfarms, for
example, are much freer from restrictions than onshore windfarms.
That's why offshore wind is expected to grow much
faster than onshore. From generating 135 TWh, 0.5% of world
energy production now, to 7% with 5,000 TWh by 2050. Costwise,
its structure is optimized for ease of production, standardized
for economies of scale and automated production at
our smart yards can reduce initial costs. Hi-Float's passive
ballast also minimizes maintenance costs. "
