Green hydrogen is produced through the electrolysis of water. The purity of the water is critical to ensure longevity of the electrolyser. Often, the best location for renewable power generation is in arid locations where pure water is scarce. However, projects are often located close to the oceans to enable subsequent export of the green hydrogen or derivative energy vectors. Desalination of the sea water is a viable route to ensure plentiful water supply for electrolysis without stressing local freshwater systems.

The other ‘hidden’ utilities for electrolysis are the Lye, or electrolyte solution and nitrogen which is essential for safe operation of the electrolyser. Local production and access to these utilities is essential. This course will look at the technologies and processes required to produce, purify, store, and use these essential utilities and feedstocks. Safety considerations when handling these materials will also be presented.

If you are investing in green hydrogen production or planning to operate an electrolyser facility, thinking beyond access to green electrons will be essential. Renewable power is key to green hydrogen, but the process relies on a range of inputs. This course will provide insights to broaden your understanding of the breadth of process requirements.


This course includes:

  • An engaging virtual training session lasting approximately three hours

  • Interactive format with dedicated Q&A sections with the expert trainer

  • Session recording & pdf file of the presentation used during the session

  • Flexible access from modern mobile and desktop devices

  • A certificate of attendance on completion of the session


Agenda

Attend live or watch the recordings. Each session includes dedicated Q&A sections throughout.

  • Electrolysis technologies overview

  • The problems with impurities

  • Water purity, desalination, and purification

  • Lye sourcing, storage, and electrolyte maintenance

  • Nitrogen for daily operations and shut-down purging

  • Nitrogen production or sourcing

  • Safety implications of these utilities and feedstocks


Meet the trainer

Stephen B. Harrison is the founder and managing director at sbh4 GmbH in Germany. His work focuses on decarbonisation. Hydrogen and hydrogen derivatives such as ammonia and methanol are fundamental pillars of his consulting practice. Stephen’s hands-on expertise extends to the full length of the value chain from production, purification, distribution, and storage through to utilisation of these green energy vectors.

With a background in industrial gases, including 27 years at BOC Gases, The BOC Group and Linde Gas, Stephen has intimate knowledge of hydrogen and hydrogen derivatives from commercial, technical, operational and safety perspectives. Stephen served 14 years as a global business leader in these FTSE100 and DAX30 companies and had the opportunity to interact with people, businesses, and operations around the world.


What Attendees Are Saying

The best part of the training was the level of engagement from the trainer; he was very clear in his explanations and was taking the time to answer all queries from trainees.
— Engineering Project Manager, SBM Offshore
Slides were informative, good delivery from the trainer, and technology worked well. Good idea to space it out over three days as it was less disruptive.
