Canadian Ice Service tracking icebergs in western Arctic for 1st
time

August 23, 2021

The Canadian Ice Service is tracking icebergs to monitor and
predict drifting patterns in the western Arctic for the first
time, according to one of its ice analysts.

Last week, the organization - a branch of Environment and Climate
Change Canada (ECCC) - dropped beacons from a Hercules aircraft
onto icebergs in the Beaufort Sea.

Adrienne White, an ice analyst with the Canadian Ice Service,
said that while it's common practice to track icebergs in the
eastern Arctic, they have never before deployed sensors in this
area.

The icebergs being monitored are castaways from the Milne ice
shelf on the northwest coast of Ellesmere Island - an area that
was historically permanently covered in ice.

Over the past century Ellesmere Island has begun to break up,
explained White, and that process has accelerated within the last
decade.

The warming climate has caused an increase in floating icebergs
breaking off of stable structures, as well as more open water
along the northern coastline.

"We're having a lot more change to these large floating ice
structures that are no longer stable in our current climate,"
White said, adding that it could mean risk for ships or coastal
communities nearby.

By dropping beacons, White said she and her colleagues at ECCC
will be able to monitor the drifting ice.

The sensor data will provide updates on the icebergs' coordinates
every hour for the next two years.

White said her colleagues are also deploying a different kind of
sensor into the Beaufort Sea to record air temperatures, sea
surface temperatures and pressure.

That meteorological data is used in global climate modelling to
forecast weather worldwide.

From Northwestern University:

The case for onboard carbon dioxide capture on long-range
vehicles

By Amanda Morris
August 18, 2021

When people talk about how to eliminate vehicles' carbon dioxide
(CO2) emission, often the conversation often focuses on
electrifying cars, trucks and buses. Yet cargo and tanker ships,
which are responsible for 3% of all CO2 emissions, are rarely a
part of the discussion.

Now a Northwestern University research team offers a practical
way to make ships CO2 neutral - or even CO2 negative - with
CO2-capturing solid oxide fuel cells. After "burning" traditional
carbon-based fuels, the fuel cell generates concentrated CO2 that
can be stored on-board the ship. From there, the CO2 can either
be sequestered or recycled into a renewable hydrocarbon fuel.

The team presents its analysis in "Viability of vehicles
utilizing on-board CO2 capture," published today (Aug. 18) in the
journal ACS Energy Letters. In the paper, the team looks at
various factors, including fuel storage volumes and mass
requirements for a wide range of vehicle classes - from
light-duty passenger vehicles to tanker ships - and compares
onboard CO2 capture to battery electric and hydrogen fuel cell
options.


"It might be harder for people to see onboard CO2 capture as
climate friendly because it uses conventional, carbon-based
fuels," said Northwestern's Scott A. Barnett, senior author of
the study. "People tend to assume hydrogen fuel cells and
electric vehicles are more climate friendly. In reality, they
often are not. Electricity might come from burning coal, and
hydrogen is often produced by natural gas, which generates a lot
of CO2 in the process."

An expert on solid oxide fuel cells, Barnett is a professor of
materials science and engineering at Northwestern's McCormick
School of Engineering. He coauthored the paper with Travis
Schmauss, a Ph.D. candidate in his research group.

Why batteries aren't a viable solution

Responsible for producing about a gigaton of CO2 each year, ships
can consume up to 250 tons of fuel per day. While it might seem
tempting to replace this massive amount of fuel with batteries,
that's simply not an option.

"Some tanker ships require enough fuel to circumnavigate the
globe as a part of their regular multivoyage operation," Barnett
said. "We calculated that the battery pack for a long-range
tanker would take up more room than the storage capacity of the
ship. A hydrogen fuel tank also would be too large. When it comes
to long-range vehicles, carbon-based fuel combined with on-board
CO2 capture is arguably the best way to make these vehicles CO2
neutral."

The proposed method also has potential advantages for
shorter-range vehicles. Battery electric and hydrogen fuel cells,
however, are already being implemented for those vehicle types,
so the researchers instead suggest implementing a CO2-neutral
range extender.

Storage solution

To store the CO2 on board, Barnett's team has proposed a
patent-pending dual-chamber storage tank. One chamber stores a
carbon-based fuel. After the fuel cycles through the fuel cell to
create energy, the CO2 byproduct is pressurized and introduced
into the second chamber. The partition between the chambers can
move - shrinking the fuel chamber as the fuel is used, making
space for CO2 in the other chamber.

"The solid oxide fuel cell is critical because it burns the fuel
with pure oxygen, yielding a concentrated CO2 product that is
storable," Schmauss said. "If we just burned the fuel with air,
it would be heavily diluted with nitrogen, yielding too much gas
to store. When the concentrated CO2 is compressed, it can be
stored in a volume not much larger than that needed for the fuel,
which saves space."

"This technology really doesn't have any major hurdles to making
it work," Barnett added. "You just have to replace the fuel tank
with the double-chamber tank and add CO2 compressors. And, of
course, the infrastructure eventually has to be developed to
off-load the CO2 and either sequester or use it."

Moving toward net-zero

With this scenario, the researchers say it is possible to make
long-range vehicles CO2 negative. This is possible with
bio-fuels, such as ethanol, because the plants used to produce
the fuel have consumed CO2 from the atmosphere. Then, after the
vehicle has used the fuel, the captured CO2 is removed from the
ship and sequestered underground or used in producing a renewable
fuel. If a vehicle uses a fossil fuel instead of a bio-fuel, then
the resulting overall cycle is closer to net-zero.
