The Netherlands Ministry of Climate and Green Growth has initiated a call for proposals for a green hydrogen demonstration project in the North Sea as part of its efforts to advance sustainable energy solutions. The demonstration project, known as Demo 1, will involve the establishment of an offshore electrolysis installation with a capacity ranging from 20 to 50 MW in the vicinity of the Hollandse Kust (Noord) wind energy area. Alongside Demo 1, a second demonstration project named Demo 2 is planned, featuring a larger capacity of up to 500 MW and located north of the Wadden Islands. The primary objective of Demo 1 is to enhance understanding and expertise in hydrogen production and transportation at sea, with outcomes from this initiative informing the development of Demo 2. The Dutch government foresees that Demo 1 will begin commercial hydrogen production by 2031, fostering insights into the costs, business case, and regulation of producing hydrogen offshore. Furthermore, the demonstration aims to stimulate hydrogen demand in industries, facilitate grid development, and support the transition towards sustainable energy practices. In parallel, Demo 2 aspires to establish a commercial-scale hybrid windfarm that generates green electricity and produces green hydrogen. The hydrogen generated will be conveyed to the mainland through a pipeline, which will be a fundamental component of the prospective hydrogen grid. Additionally, surplus electricity from Demo 2 not utilized for hydrogen production will be transmitted to another offshore windfarm, contributing to the establishment of a blueprint for future offshore energy hubs. The Dutch government views offshore hydrogen production as pivotal for enhancing industry sustainability, bolstering energy self-sufficiency, and realizing climate targets. The concurrent implementation of Demo 1 and Demo 2 underscores the commitment to technological advancements, operational efficiency, and the seamless integration of offshore hydrogen production within the broader energy landscape.
