Shell's planned 200MW Rotterdam electrolyser project will only meet around 10pc of hydrogen demand from its nearby 420,000 b/d Pernis refinery, the firm's commercial manager of hydrogen assets Katharina Gruenberg has said.
The capacity of the Hydrogen Holland 1 project — which Shell expects to be the largest in Europe when it comes online in 2024 — and demand from the connected refinery demonstrates the magnitude of the scale-up task facing the hydrogen industry, which was repeatedly stressed by delegates at Reuters' Hydrogen 2022 Conference in Amsterdam this week.
Shell has said the plant would produce 50,000–60,000 kg/d, implying hydrogen demand from the refinery of around 500-600 t/d.
Low-carbon hydrogen may need to displace 40mn t/yr of hydrogen consumed globally by the refining sector, with almost all current supply derived from fossil fuels with unabated carbon emissions. Refineries use hydrogen to remove impurities from fuels and break heavy molecules into gasoline, diesel and kerosene.
The global hydrogen market of around 90mn t/yr may grow five- or six-fold by 2050, according to the International Energy Forum, with existing demand from refining, fertilisers, and chemicals potentially compounded by need from hard-to-abate industry and mobility sectors. Hydrogen from low-carbon sources would need to increase by 500- to 600-fold, as it accounts for less than 1pc of production today.
Shell is also looking at hydrogen from natural gas with carbon capture and storage (CCS), as it seeks to use all available routes to meet the expected massive demand.
"We need to look at CCS for our [refining and chemical] assets anyway," Gruenberg said.
The scale of hydrogen projects is increasing. Shell last year launched a 10MW electrolyser in Cologne, Germany, and a 20MW electrolyser in China's Hebei province. It expects to make a final investment decision on the 200MW Rotterdam electrolyser in the coming weeks, to allow first production in 2024. And it is considering gigawatt-scale production from the North Sea by 2030, Gruenberg said.
