H2Tech - Q1 2021 - 9


Equinor, OGE,
thyssenkrupp study H2 use
in steel production
Norwegian energy company Equinor,
gas transmission operator OGE and steel
producer thyssenkrupp Steel Europe
recently concluded a joint feasibility
study on the possibility of supplying
thyssenkrupp Steel's Duisburg site with
blue H2 to help decarbonize operations
over the short- and mid-term.
The H2morrow study found that the
decarbonized production and supply
of blue H2 from natural gas to
Germany's largest steel plant in
Duisburg is technically feasible. The
study's premise was the production of
H2 from natural gas with permanent
offshore storage of CO2 accrued in the
process. The study evaluated several
options for sourcing and transport of
H2 to thyssenkrupp's Duisburg steel
production site, as well as options for
transport and storage of CO2.
Three possible locations for H2
production identified a potential site
on the Dutch coast in Eemshaven and
two other sites on the German North
Sea coast. With regard to production
capacity, two scenarios have been
evaluated: 1.4 GW and 2.7 GW. The study
concludes that economically viable H2
transport via pipeline is possible. The
study also investigated potential CO2
storage sites, such as the Northern
Lights project in Norway and the
Porthos project offshore of Rotterdam.
Either ships or pipelines may be viable
as CO2 transport solutions.
Based on market forecasts by
external analysts, the study estimates
a price for blue H2 of approximately
€2.1/kg (€58/MWh), based on an
expected future and long-term average
natural gas price of €23/MWh.
In addition to further technical
detailing, the study stipulates the need
for further clarification of the regulatory
frameworks in Germany and the EU
related to the conversion of natural
gas pipelines to dedicated H2 pipelines.
It also requires clarification on H2
transport. The H2morrow steel feasibility
study concludes that the entire project's
value chain could be established by
2027, at the earliest.

Tenaris to work with Edison,
Snam on green H2
Tenaris, Edison and Snam intend to
launch a project to decarbonize Tenaris'
seamless pipe mill in Dalmine through

the introduction of green H2
in production processes related to
electric arc furnace steel. This project
will implement the first application
of green H2 on an industrial scale to
decarbonize Italy's steel sector.
The companies will collaborate
to identify and implement suitable
solutions for the production, distribution
and use of green H2 at the Tenaris mill.
The project aims to generate H2 and O2
through a 20-MW electrolyzer that will
be installed at the Dalmine plant and to
adapt the steelmaking process to use
green H2 instead of natural gas.
The initiative may also include the
construction of a storage site for the
accumulation of high-pressure H2 and
the use of O2 , locally produced through
electrolysis, within the melting process.
After the initial test, the three companies
will evaluate whether to expand the
collaboration to other stages of the
production process, thereby extending
the use of H2 .

Naturgy, Enagas team up
to build clean H2 plant
in Spain
Spanish utility Naturgy and gas
system operator Enagas are joining
forces to build a plant capable of making
9,000 metric tpy of clean H2 . The
companies will build a 400-MW solar
plant to power a 60-MW electrolysis
facility near the site of a coal-fired plant
in northwestern Spain that Naturgy
closed last year. Spain aims to install
4 GW of electrolysis capacity by 2030,
one tenth of the EU target for the
entire bloc by that date.

BP and Ørsted to produce
green H2 at Lingen refinery

BP and Ørsted plan to jointly develop
a project for industrial-scale production
of green H2 . In their proposed Lingen
green H2 project, the two firms intend

to build an initial 50-MW electrolyzer
and associated infrastructure at BP's
Lingen refinery in northwest Germany.
The plant will be powered by renewable
energy generated by an Ørsted offshore
wind farm in the North Sea, and the H2
produced will be used in the refinery.
BP and Ørsted will work together
to further define the project and
plan to take FID in early 2022. The
companies anticipate the project could
be operational by 2024. The 50-MW
electrolyzer is expected to produce
1 metric tph of green H2 , or almost
9,000 metric tpy. This would be
sufficient to replace around 20% of the
refinery's current gray H2 consumption,
avoiding around 80,000 metric tpy
of CO2 equivalent emissions-
equivalent to the emissions from
around 45,000 cars in Germany.
The Lingen project is also intended
to support a longer-term ambition
to build more than 500 MW of
renewable-powered electrolysis capacity.
This could provide green H2 to meet
the refinery's entire H2 demand and
provide feedstock for potential future
synthetic fuel production.

First trial of H2 home heating
begins in UK
Energy regulators in the UK are
funding the world's first trial of a
100% green H2 generation, storage
and distribution network to heat
300 homes in Scotland, as part of the
UK and Scotland's ambition to achieve
net-zero carbon emissions within 30 yr.
UK energy regulator Ofgem is
awarding $24 MM (£18 MM) to a project
in Fife, Scotland to heat 300 homes
with green H2 produced via offshore
wind power. The project will receive
additional investment of $9.2 MM
(£6.9 MM) from Scotland's government.
The H100 Fife project is scheduled to
begin construction in 2021, while the
H2 network will go live in 2022.
The project will be operational for
4.5 yr, until March 2027, and seeks to
prove if green H2 is a viable solution to
reduce emissions by providing home
heating in the UK. The initial 300
customers in the Fife project will receive
a free H2 hookup, free replacement H2
appliances and free maintenance over
the length of the project. The customers
will pay the same amount for H2 gas
as they would pay for natural gas. At
present, central heating is responsible
for up to one third of the UK's
greenhouse gas emissions.
