ERM Dolphyn is a novel green hydrogen project, enabling the production of green hydrogen at scale from offshore floating wind. The ERM Dolphyn concept employs a modular design, integrating electrolysis and a wind turbine on a moored floating sub-structure to produce hydrogen from seawater using wind power as the energy source.

The project has the potential to deliver green hydrogen at GW-scale, meeting the demand for green hydrogen that is growing exponentially. A 10MW demonstrator project is currently under development with operations starting in mid 2020s. Co-development in 200+ MW scale projects are underway in Scotland/ Celtic Sea region. The ambition for GW-scale project is to expand from the UK to new markets such as Europe, the US, Japan and Korea.

This presentation will be focused on the demonstrator project. We will briefly present an overview of the ERM Dolphyn concept and key considerations for project development. This is then followed by a discussion on key challenges and learnings in developing a novel green hydrogen project which is related to two existing industries: offshore renewables and offshore oil and gas.
