Shell awards services contract for green hydrogen hub in the Netherlands

Shell Nederland Verkoopmaatschappij BV (Shell) has awarded Worley a services contract to support the development of a new 200 megawatt electrolysis-based hydrogen plant in Rotterdam, the Netherlands.

The new plant will be powered by renewable energy from an offshore windfarm that is currently in development. Once complete, the green hydrogen plant will be one of the largest commercial green hydrogen production facilities in the world. Operations are scheduled to start by 2023 and are estimated to produce 50,000 – 60,000 kilograms of green hydrogen per day. The green hydrogen produced will initially be used to decarbonize Shell’s nearby refinery in Pernis and support the industrial use of hydrogen in the heavy transportation industry.

Under the contract, Worley will provide early engineering services for the green hydrogen plant including integration with other assets such as offshore wind, pipelines, electrical grids and Shell’s Pernis refinery.

The services will be executed from Worley’s offices in The Hague, with support from Worley’s global hydrogen subject-matter experts and Global Integrated Delivery team in India.

“As an Australian company operating globally, we are pleased to be working with Shell on this first-of-itskind project. We look forward to supporting Shell’s strategy to be a provider of net-zero emissions energy products and this project is an example of how Worley can help our customers achieve their goals and own purpose of delivering a more sustainable world,” said Chris Ashton, Chief Executive Officer of Worley.

Authorized for release by Nuala O’Leary, Group Company Secretary.
