SPECIAL FOCUS PATHWAYS FOR SUSTAINABLE H2
bustion is used for the cracking process.
For this to be a sustainable solution, the
ammonia production must be clean, with
little or zero greenhouse gas emissions.
The primary goal is that no CO2
will be
emitted from the production or from the
use of ammonia in jet turbines. Nitrogen
oxide (NOx
) emissions from turbines
must be controlled, and the safety aspects
of toxic ammonia should be handled.
Large-scale, emissions-free ammonia
production. Several large projects
are emerging to produce low-carbon ammonia
from natural gas. The high production
capacity of such plants will typically
be 10-100 times larger than from water/
clean-power electrolyzer plants, and the
production cost is less than half.
Large-scale ammonia synthesis, based
from natural gas and nitrogen
on clean H2
from an air separation unit (ASU), is available.
The author's company has developed
an emissions-free proprietary processa
produce H2
to
and ammonia from natural gas
with CCS (FIG. 2). The technology is based
on proven processes such as autothermal
reforming (ATR), fed by oxygen from an
ASU, a palladium membrane or pressure
swing adsorption (PSA) for H2
and the cryogenic separation of CO2
separation,
. This
process solution has been further developed
to an ultra-high CO2
capture rate of
nearly 100% and is independent of clean
power input. Additionally, the process can
be tailor-made to fit a client's project needs,
and this shows that world-scale, emissionsfree
H2
/ammonia plants can be built now.
Hopefully, the aviation industry will
include clean ammonia in its development
strategy as an alternative path for
low-carbon aviation. It is urgent to address
and solve the many challenges of reaching
our global climate goals today.

Fluid System Solutions for H2
Applications
Hydrogen has great potential as a zero-emission fuel source, but it can be
hard to handle. Hydrogen must be stored and dispensed at high pressures
to achieve the energy density required for use in fuel cell vehicles and
infrastructure, but as a small-molecule gas, it can migrate through tiny
crevices and diff use into materials designed to contain it. Also, hydrogen
undergoes rapid thermal and pressure changes as it is transferred,
further complicating its use as a fuel source.
Specifying high-performing fl uid system solutions (fi ttings, valves, tubes,
hoses) designed for hydrogen applications is the best way to achieve
long-term, leak-tight operation of fueling and on-vehicle hydrogen systems.
In this presentation, we will cover:
* The challenges of H2
as a mobility fuel
* How to design for safe, leak-tight hydrogen use
* Characteristics of high-performance hydrogen system fi ttings
* Effi cient installation and maintenance practices
