TECHNOLOGY SPOTLIGHT
expensive precious metals that account
for nearly 50% of the electrolyzer cost.
A sponsored research program is
focused on replacing iridium, a precious
metal found only inside asteroids, with
earth-abundant materials that meet or
exceed the performance characteristics of
iridium. NewHydrogen has also identified
additional components and materials
in electrolyzers where meaningful cost
reductions can be performed. While
iridium is the O2 catalyst, its counterpart
on the H2 side is platinum, a material so
rare that only 200 tpy are mined.
Another critical component is the
porous transport layer-i.e., the gas
diffusion layer-which facilitates the
movement of water and gases to and
from the catalyst surfaces. According
to the National Renewable Energy
Laboratory, the catalysts, membrane
and porous transport layer assembly
account for more than 50%-75% of the
capital cost of the electrolyzer stack.

Shearwater Energy selects
NuScale Power technology
for wind-H2 project

large thermal plants without the high cost,
long construction time and environmental
legacy. Power generation at Wylfa could
begin as early as 2027.

Nel Hydrogen Fueling wins
first OIML certification
for H2 dispenser
Nel Hydrogen Fueling was awarded
the world's first OIML R 139 certification
for its 700-bar H2 dispenser system in
late 2020. H2 has the lowest density
of all gases, making it one of the most
challenging gases for accurate mass
measurement. Nel has fulfilled the strict
requirements listed in the standard for
measurement accuracy. The certificate
is acknowledged internationally and
simplifies the national approval process.
The International Organization of Legal
Metrology's OIML R 139 is an international
model regulation that describes how to
build an H2 mass measurement system
for H2 fueling stations.

Havyard to develop zeroemission H2 vessels for Europe

Shearwater Energy Ltd. is developing
a wind-SMR (small modular reactor) and
H2 production hybrid energy project in
North Wales, UK. The project will provide
3 GWe of zero-carbon energy and
produce more than 3 MMkgy of green H2
for use by the UK transport sector.
Shearwater has selected the SMR
technology being developed by NuScale
Power to provide the clean, baseload and
load-following energy for the proposed
hybrid energy project. Shearwater has
signed an MOU with NuScale Power to
advance the proposed project.
Under the MOU, Shearwater and
NuScale will explore opportunities for
the combined generation of nuclear
power based on NuScale's leading SMR
technology, offshore wind energy and
H2 production at sites in the UK, with
a flagship opportunity being explored
at Wylfa on Anglesey. The combination
of the two low-carbon-generating
technologies will enable the achievement
of similar performance characteristics to

A European player has contracted
Havyard to develop a zero-emission ship
concept for cargo transport. Havyard will
combine its expertise in H2 energy systems
and ship design to develop a new concept
for transporting cargo between European
ports on a large, H2-fueled ship that can
sail longer distances with zero emissions.
The partner has taken note of Havyard's
H2 expertise and work on zero-emission
vessels, in addition to Havyard Design's
advanced simulation tool for developing
energy-efficient solutions. Havyard
established Havyard Hydrogen AS as a
spinoff of the company's research and
development work in the area of H2
propulsion for large vessels. This R&D work
has been carried out over many years-e.g.,
through the Pilot-E project FreeCO2ast.
Havyard's Ocean LAB digital twin
simulation will be used to create a
digital mockup of the ship and put it into
operation on a virtual ocean. This will
allow experimentation with hundreds
of alternatives to clarify the size and
framework conditions for the ship.
Digital copies will be created of both the
ship and the planned route, including
information about weather and wind,
current and wave data. In this way, the
ship will have been in digital operation

before being built, and adjustments can
be made to ensure maximum efficiency in
terms of environment and budget.

Alfa Laval joins with
marine sector to fast-track
fuel cell technology
Alfa Laval has joined a project with
DTU Energy, Haldor Topsoe, Svitzer and
the Mærsk Mc-Kinney Møller Center
for Zero Carbon to accelerate the
development of solid oxide fuel cell
(SOFC) technology, which can use green
fuels to generate electricity. Alfa Laval will
head the development initiative, with the
aim to find scalable solutions for noncarbon fuels for the shipping industry.
The International Maritime
Organization (IMO) targets a 50%
reduction of vessel-related greenhouse
gas emissions by 2050. Today, global
shipping accounts for around 3% of
global carbon emissions, a share that
is estimated to increase in the coming
decades as other industries tackle climate
emissions. To achieve the long-term target
of decarbonization, the industry must shift
toward new fuel types and technologies.
To accelerate the development of
viable technologies, a coordinated effort
within applied research is needed across
the entire supply chain. The project,
SOFC4Maritime, will target utilization
of future green fuels, such as ammonia,
H2 or biomethane, for power production
onboard marine vessels. Since ships have
a lifetime of 20 yr or more, zero-emission
vessels must begin entering the global
fleet by 2030 for a 50% reduction to be
achieved by 2050.

Linde, Daimler collaborate on
liquid H2 refueling technology

Linde and Daimler Truck AG are
working to jointly develop the next
generation of liquid H2 refueling
technology for fuel cell-powered trucks.
Together, the companies will focus
on a new process for handling liquid
hydrogen ( " subcooled " liquid hydrogen,
or " sLH2 technology " ).
This approach allows for higher storage
