FRANKFURT, Feb 26 (Reuters) - Royal Dutch Shell in
Germany aims to produce aviation fuel and naphtha made from
crops and renewable power and to increase to commercial scale an
electrolysis plant that makes fossil-free hydrogen, as it seeks
to move away from crude oil.
The energy major told an online conference on Friday it had
applied for subsidies to carry out the work from the European
Union and from German funds earmarked for decarbonisation.
Fabian Ziegler, head of Shell Deutschland, said several
hundred million euros should be spent per year, but he did not
give a desired ratio between company and public funding.
The global Shell group has set itself a goal of net zero
emissions by 2050.
At Wesseling, part of the Rheinland refinery, Shell plans to
use green electricity and biomass to produce synthetic
power-to-liquids (ptl) in a carbon-free way to replace, over the
long term, conventional jet fuel and naphtha.
The 100,000 tonnes/p.a. ptl plant could be built from 2023
and start producing in 2025.
Shell also gave a timeline for building a 100 megawatt (MW)
electrolysis plant, to be called Refhyne II, scaling up from an
existing 10 MW plant.
Hydrogen is considered a green fuel when electricity from
renewable energy sources is used in its production.
Shell has begun securing offshore wind power assets whose
electricity it could use as feedstock for electrolysis.
Through its latest purchase of Next Kraftwerke, a virtual
power plant (VPP) operator, it gets access to aggregated
biomass-to-power and solar
plants.
A final investment decision for Refhyne II is due this year
and production could start by the end of 2025, Ziegler said.
The Berlin government last summer earmarked 7 billion euros
for the build-up of green hydrogen in Germany, plus a further 2
billion euros to set up partnerships with other countries, to
introduce the alternative fuel across industries and energy.
The market's build-up will take many years but there are
clear targets in place for 2030, accompanied by plans to
repurpose existing gas and oil transport infrastructure for
example around existing refinery clusters.
Hydrogen has a high energy content by mass, but conversion
losses from electrolysis and high costs involved in readying it
for delivery pose challenges.
Costs of producing green hydrogen of 5-6 euros per kg must
come down, given that fossil fuels-based hydrogen costs 1.50
euros/kg, he said.
The plans for Wesseling tie in with other European Shell
initiatives, with partners, to build electrolysis production in
Hamburg and in the Netherlands.
Shell wants to build up transport sector delivery chains for
hydrogen and provide electric charging.
