DNV will provide safety, environment and sustainability technical assurance for the HOEST PtX Esbjerg project under a contract signed with Copenhagen Infrastructure Partners (CIP).
The Danish power-to-X development aims to produce green ammonia from a hydrogen feedstock using a 1GW electrolyser. This is expected to reduce CO2 emissions by about 1.5m tonnes per year – the equivalent to removing 750,000 cars from roads.
The ammonia will then be used for fertilisers and maritime fuels, contributing to the long-term sustainability of agriculture and shipping.
DNV has delivered a number of services to Hoest leading up to this contract, including risk appraisals, early concept life cycle assessment on CO2 emissions, and price and sustainability impact studies.
DNV is developing new specifications for the safety of PtX facilities and the assessment, verification and certification of low-carbon hydrogen and ammonia.
The specifications aim to address traditional industrial plant safety concerns and the challenges posed by the production of hydrogen and ammonia from renewable sources.
“As the demand for green hydrogen and ammonia increases, it is more important than ever to ensure that these industrial processes are conducted safely and sustainably,” said David Dupont-Mouritzen, Project Director of HOEST PtX Esbjerg.
CEO of Energy Systems at DNV Ditlev Engel added: “Strategic power-to-X projects like HOEST PtX Esbjerg are needed on the pathway to net zero, as we highlighted in DNV’s 2022 Energy Transition Outlook, and in this case particularly important to support the ambitious Danish target of a 70% reduction of CO2 emissions by 2030.
“As hydrogen and power-to-X sites develop it is vital that we do not compromise on safety. DNV has undertaken technical assurance projects in Denmark for more than 40 years and we are pleased to continue to collaborate with CIP as a trusted voice for safety and sustainability.
“Our new PtX specifications will play a crucial role in supporting the growth of this sector, while protecting the health and safety of workers and the environment.”
