Multimegawatt high-temperature electrolyser to generate green hydrogen for production of high-quality biofuels
Within the scope of the MultiPLHY project, HTE (high-temperature electrolyzer) by Sunfire and HPU (hydrogen processing unit) by Paul Wurth have been installed and the commissioning is ongoing. Neste is responsible for the refinery integration and operations of the demonstration unit. The produced hydrogen will be fed into the refinery processes and utilized in the production of renewable products.
Mechanical completion of the full demonstration unit was reached on May 30, 2023.Key activities included:
overall safety of the electrolyzer
installation has been assessed according to the Neste’s systematic framework
for process safety.The
siting of the unit in the refinery area has been assessed to select a location
where consequences of potential accidents are minimized.The
hazards and risks of the electrolyzer
and hydrogen processing unit have been evaluated in collaboration with the
project partners to ensure that sufficient process safeguards are in place for
safe operation and the risks are low enough for the refinery environment.The
safe integration of the unit to the refinery processes is tested and verified
during commissioning activities. Likewise, the correct implementation and
functionality of the safety systems in the electrolyzer
and hydrogen processing unit are tested and verified by project partner’s
commissioning tests before starting the hydrogen production and supply for refinery use.Safe
and reliable operation of the unit will be accomplished by trained site
operators with the technical support from the project partners when necessary.
