Hydrogen Building Blocks: H2 View launches Class of H2 training on electrolyser technologies

Following on from its inaugural series of training modules, H2 View’s Class of H2 returns in March (2024) with a new series of modules devoted to one of the hottest topics in hydrogen – electrolyser technologies.

Moving from fundamentals to Hydrogen Building Blocks, Stephen B. Harrison of sbh4, will deliver four detailed sessions on March 12-13, 2024,  to provide introduction, education and analysis into the technologies underpinning green hydrogen and ammonia.

Aimed at investors, CEOs and engineers alike, the training is aimed at expanding business knowledge with insight into:

  • Ultra-Pure Water for Electrolysis
  • Mature Electrolysis Technologies for Green Hydrogen/Ammonia
  • Emerging Electrolysis Technologies
  • Technologies for Green Ammonia

Ultra-Pure Water for Electrolysis

Electrolysis water usage remains one of the most recurring topics in the hydrogen space.

The dominant path to green hydrogen is splitting ultra-pure water using renewable electrical power on an electrolyser. For each kg of green hydrogen produced, as much as 9-10 litres of water are consumed by electrolysis.

This equates to circa 200 litres of water per MW of electrolyser capacity. To generate that amount of ultra-pure water, circa 1.5 times as much fresh water is required. And to generate desalinated fresh water, approximately twice as much seawater is required.

There are many steps between seawater and ultra-pure water. If any of those fails, the electrolyser stack could be damaged beyond repair. If the water processing plant fails, the electrolyser must shut down, resulting in failure to supply off takers, or causing problems with downstream ammonia synthesis. Reliability and consistent ultrapure water quality are key.

In this module, learn all about the role of water in electrolysis, all of these requirements in water usage and purification, the technologies to meet these requirements, and so much more besides. Specifically, get the inside track on:

  • Electrolyser feed water specifications
  • The business case for investing in ultra-pure water
  • De-risking billion-dollar investments with an informed strategy
  • Proven technologies for desalination and purification

Mature Electrolysis Technologies for Green Hydrogen/Ammonia

Green hydrogen and ammonia are widely acknowledged to be two key – and intrinsically linked – pillars in the diversified and sustainable energy landscape of tomorrow.

On one hand, hydrogen is a clean and renewable energy source with the highest energy content by weight among alternative fuels – and around six times more energy than ammonia. What it makes up for in potential, however, it currently lacks in terms of infrastructure and supply.

Ammonia, meanwhile, is the most popular substance as a green hydrogen carrier and has firmly entered the conversation in recent years for both its clean fuel potential and its readily available infrastructure. The total hydrogen content of ammonia is higher than other fuels, rendering it suitable to convert to hydrogen, and it does not carry carbon.

Several pathways already exist for green hydrogen/ammonia production. Hydrogen can be produced from ammonia through several technologies, such as electrochemical, photocatalytic and thermochemical processes, while PEM electrolysis has its origins in the 1970s and the invention of the solid polymer electrolyte (SPE) membrane and has scaled up in the past 50 years to challenge the dominance of alkaline electrolysers.

In this module, learn all about the proven pathways and electrolysis technologies for green hydrogen and ammonia production, from PEM electrolysis to alkaline technologies and the catalysts, efficiencies and economics in-between.

Emerging Electrolysis Technologies

In the same way that PEM electrolysers have innovated and scaled up in the past 50 years to challenge the dominance of alkaline electrolysers, new electrolyser technologies are now emerging.

These technologies are challenging the green hydrogen paradigm, and presenting compelling new business opportunities.

One high-potential electrolyser technology that is in the ascendancy, for example, is called AEM due to the use of an anion exchange membrane. In the past five years, the rise of AEM appears to have gained momentum internationally and its entry into the major league of green hydrogen production processes would now seem to be unstoppable.

In this module, Class of H2 moves from the mature and proven electrolyser technologies, to the emerging and challenger pathways and their potential. Better understand the platforms open to your business, get to grips with the efficiencies, economics and safety considerations of your chosen technology route, and equip yourself with the toolkit of knowledge to succeed in the electrolysis sector.

Technologies for Green Ammonia

For several years, attention has focused on green hydrogen as a clean energy vector. Produced on electrolysers from renewable electrical power generated by wind, solar or hydro schemes, green hydrogen is regarded as a fuel with a very low-carbon footprint.

Yet, the conversion of green hydrogen to green ammonia has been an established concept for many decades, and green ammonia has firmly entered the conversation in recent years for both its clean fuel potential and its readily available infrastructure.

Ammonia is readily liquefied and as a liquid it has a high volumetric energy density, about 50% higher than liquid hydrogen. The savings in shipping costs of liquid ammonia, compared to liquid hydrogen mean that CAPEX and OPEX savings from the shipping operation can be routed to the ammonia conversion facility. For long distances, such as the Australia to Europe route, liquid ammonia is considered the most cost-effective mode of green hydrogen transportation.

There is also the same historic motivation to produce green ammonia at an applications level: to generate nitrogen fertilisers, a use case that will endure.

How, then, is ammonia produced and what are the pathways to green ammonia now and in the future?
