H2Tech - Q1 2021 - 7

TECHNOLOGY SPOTLIGHT
density, greater range, faster refueling
and improved energy efficiency. The new
process will use higher-than-ambient
pressure levels and special temperature
control, which avoids boil-off effects and
return gas during refueling, and will not
require complex data communication
between the filling station and the truck
during refueling. Overall, the technology
allows simpler filling station concepts. The
improved energy storage density is due
to the higher-than-ambient pressure level,
which increases the H2 mass in the tank.
The companies plan for the first
refueling of a prototype vehicle at a pilot
station in Germany in 2023. Linde and
Daimler Truck AG are planning for a high
level of transparency and openness around
the relevant interfaces of the jointly
developed technologies to encourage a
global mass market for the process.

STORAGE
McDermott awarded liquid H2
storage expansion study
McDermott International Ltd.'s
CB&I Storage Solutions business has

H2Tech Half Page Horizontal - Golden Egg.indd 1

been awarded a study by a leading
natural gas producer to research
opportunities to expand current
liquid H2 storage capacity limits.
In 1960, CB&I Storage built the first
liquid H2 sphere with the capacity to
store 170 m3 of H2. Over the last 60 yr, the
company has expanded that threshold
to 5,000 m3. CB&I plans to continue to
advance its technology to further refine
its portfolio of storage solutions.

TURBOMACHINERY
Mitsubishi tests engine
with 100% H2

The test used MHIET's lean-burn
gas GSR series engine with additional
modifications-fuel supply method,
ignition method, timing of intake air valve
closing, excess air ratio, etc.-for optimum
combustion to determine the conditions
that ensure stable combustion with
H2-only firing and premixed firing.
Converting the test results, the
maximum output is estimated to be
340 kW for a 6-cylinder engine and
920 kW for a 16-cylinder engine. MHIET
will accumulate more test data to help
realize multi-cylinder H2 engines and
make these engines available for the
H2 economy in the 2030s.

Mitsubishi Heavy Industries Engine &
Turbocharger Ltd. (MHIET) is strengthening
its efforts to develop an H2 engine based
on its existing diesel and gas engines.
A modified, single-cylinder gas engine
based on MHIET's reciprocating gas
engine GSR series (6-16 cylinders) was
installed at AIST's Renewable Energy
Institute in Fukushima, Japan. The test
was carried out to identify the conditions
to achieve stable combustion of 100% H2
without emitting CO2.
