Liquid CO2 Test Ship Launched in Japan

Mike Schuler
March 28, 2023

Mitsubishi Shipbuilding Co., a subsidiary of Mitsubishi Heavy
Industries, has launched a test ship for transporting liquefied
carbon dioxide (LCO2).

The launch ceremony took place at the Shimonoseki Shipyard in
Yamaguchi Prefecture, Japan, with representatives from ship owner
Sanyu Kisen Co. and other partners in attendance.

The project is being conducted in partnership with the New Energy
and Industrial Technology Development Organization (NEDO), an
organization of the Japanese government that works to promote the
research, development, and demonstration of new energy and
industrial technologies, in support of its carbon dioxide
capture, utilization, and storage (CCUS) projects.

The Engineering Advancement Association of Japan (ENAA) will
charter the ship, while additional project partners, including
Kawasaki Kisen Kaisha ("K" LINE), Nippon Gas Line Co., and
Ochanomizu University, will conduct R&D on pressure control,
stability, and low-cost transportation of LCO2. Mitsubishi
Shipbuilding is responsible for the ship's design and
construction, drawing on its expertise in gas handling

The ship is scheduled for delivery in the second half 2023
following outfitting and sea trials.

With demand for LCO2 carriers expected to grow, Mitsubishi
Shipbuilding aims to develop the necessary technologies for LCO2
vessels to establish a CCUS value chain. The company will also
focus on decarbonization and marine innovation as part of its
"MARINE FUTURE STREAM" growth strategy.

From Deutsche Welle:

Sky-high kites aim to tap unused wind power

High-altitude winds remain a huge untapped source of
renewable energy, but a race to the sky is well underway.

Tim Schauenberg
March 27, 2023

For a child, the simple act of flying a kite can be exhilarating;
running and pulling at the line to send it ever higher into the
sky where the winds dance to their own wild tune.

Those same winds that captivate young imaginations are also
working their magic on a growing body of researchers intent on
harvesting what are known as high-altitude winds. At a height of
200 meters (656 feet) and more, winds tend to blow stronger and
more steadily than those closer to the ground.

These winds are so strong, in fact, that they could be used to
generate more electricity than we need and significantly more
than wind turbines on land can produce. A doubling of wind speed
can theoretically generate up to eight times more power.

Moritz Diehl, who heads the Department of Microsystems
Engineering at the University of Freiburg, said harvesting
high-altitude winds is one of the "most promising" technologies
for generating renewable energy in the future.

"You see all the sky above conventional turbines, and you think
all this wind energy is just blowing there and it's not used," he

Stephan Wrage, CEO of the German wind power company
SkySails-Power, wants to change that and make the "largest yet
untapped source of renewable energy worldwide" suitable for mass

And he's not the only one. For years, engineers, various startups
and international companies have been in a race to bring
high-altitude winds down to Earth at low cost. Many have failed
in their attempts and some have gone bankrupt. But others are on
the verge of bringing their flying power plants to the market.

Flying wind turbines and other ideas

One of the first projects to attract attention was launched by
the US energy company Altaeros in 2010. Their prototype was a
generator attached to a helium balloon — in other words, a wind
turbine without a heavy base and tower.

Tested in Alaska, it was connected to the ground by a cable.
According to the company, it produced energy for about 50
households at an altitude of 600 meters.

Around the same time, the German company SkySails developed a
high-altitude kite to pull entire container ships. The idea was
to save diesel used to run the engine, by up to 10%.

Although the test with the kite worked, the shipping company went
bankrupt and neither the kite nor the helium wind turbine
conquered the market. But both prototypes pointed to one thing:
harvesting high-altitude winds requires flying power plants.

Google investment generates hype, until crash

Enter Google. In 2013, the tech giant bought the US airborne wind
energy company Makani for an undisclosed amount, triggering
euphoria in the niche sector. Their flying power plant, a device
about the size of a small aircraft, climbed to an altitude of
around 300 meters where it circled in a continuous and automated

The high speeds propelled small wind wheels on the wings, which
generated electricity. At the time, Moritz Diehl thought it
sounded "crazy" — but it worked. A single flying power plant made
enough energy for 300 households, according to Makani.

It seemed to be the breakthrough everyone had been waiting for,
until a device crashed into the sea during a test mission.
Google's parent company Alphabet subsequently dropped the
project, expressing doubts about the economic viability of the
flying power-drone.

Not the end, but the beginning

The end of Makani didn't spell the end of airborne wind energy. A
new wave of startups has kept working on increasingly small
devices that use ever less material. Some have pursued Makani's
approach, while others have attached their drone to a rope which
tugs at a generator. Still others took the same approach but
replaced the drone with a kite.

Among them is SkySails-Power — successor to the bankrupt German
company behind the towing kites. Now specializing in energy
generation, it has come up with a device that uses a "pumping
cycle" to generate power. The kite takes off automatically,
directs itself against the wind and unwinds a rope from a
generator. It flies in a figure eight, constantly tugging at the
rope and creating energy.

The kite is designed to remain airborne for hours, days and
weeks. In bad weather or in dangerous conditions, it triggers an
alarm and can be recovered.

Not designed to replace existing wind power

Though the sector still requires considerable investment and
clarification of many regulatory questions around air traffic,
Wrage said the technology could help the 1.4 billion people
globally who live off-grid, and often use dirty diesel generators
to power their homes.

According to a study by members of the wind industry itself,
airborne wind energy could become significantly cheaper than
diesel — and even cheaper than traditional wind energy.

SkySails-Power, currently leader in the sector, has sold a first
unit to Mauritius. The company is looking to build a
high-altitude wind hub in East Africa and operate offshore kite
wind farms.

SkySails said a single one of its kites can create energy for up
to 500 households, using 90% less material than traditional wind
turbines. Other advantages include flexibility of location.

"You could also operate them above the forest. You could stop
them operating and or even land if there's a swarm of birds
passing by," said Diehl.

Rishikesh Joshi, an aerospace engineering researcher at the Delft
University of Technology, said "it will still take a few years"
before the technology makes a difference. "The wind industry also
took around 40 years to develop to be this cheap," he said.

In the meantime, traditional turbines continue to turn. And even
when the airborne wind energy sector is more advanced, the idea
is not to replace existing turbines but to make greater use of
the winds that blow high above the ground.
