An Exciting Collaborative Growth Project
Defining & Creating the Green Hydrogen Economy in Northern Ireland
B9 Power-to-X systems produce hydrogen, oxygen, grid services and heat using electrolysis powered by renewable energy and subsequently store and distribute these gases for later use in heat, power, transport and industrial applications. The block diagram below shows the typical system elements….
Power-to-X Elements Explained
- Wind energy is imported from the electrical grid during windy nights so that the System Operator does not have to switch wind turbines off. This will reduce compensation payments to wind farmers and help to keep electricity bills low. It will directly reduce curtailment and thereby support continuing wind farm investor confidence.
- The heart of a Power-to-X project is the electrolyser machine. It consumes electrical energy through the electrolysis of water to produce hydrogen, oxygen, heat and grid services. 9 tonnes of water is converted to 1 tonne of hydrogen and 8 tonnes of oxygen. All modern designs are high pressure in that they produce hydrogen at up to 35bar without the need for a compression step. Traditional Alkaline and PEM (Proton Exchange Membrane) machines are being challenged by emerging Membrane Free Electrolyse technology.
- Green hydrogen can be compressed to 500bar pressure for onward dispensing into buses and HGV tractor units which store onboard at 350bar. We expect cars to be mostly battery electric in future and therefore not a significant market for hydrogen fuel. Dedicated pipelines can be used for storage and transportation of 100% hydrogen and/or once legislation has been finalised hydrogen can be injected into existing natural gas pipelines up to a limit of 20% by volume without the need to upgrade home appliances.
- The market for pure hydrogen in transport will naturally take some time to appear because it depends on older vehicles being retired and new fuel cell versions being procured to replacing them. Electrolysers can be installed much faster that this so it becomes imperative to find something else to consume the hydrogen. An attractive option is to synthesise methanol from hydrogen and carbon di-oxide using a catalytic reactor. There is already a market for Methanol, and a sub-section for Green Methanol, and this product can be used as fuels, additives and/or precursors for the chemical industry.
- There are many uses for oxygen but a prominent application can be found at sewage treatment plants where conversion of the secondary treatment process from aeration to oxygenation saves energy in electrically operated air blowers and provides capacity headroom. This is especially useful if the existing plant is already capacity constrained and operating at full throughput as expensive upgrades / extensions can be deferred or avoided.

As a independent developer of renewable energy projects over the last 28 years, B9 has always been agnostic to the choice of technology supplier that we contract with….. until now that is! When it comes to electrolysers, which are at the heart of B9’s Power-to-X projects, we have discovered a novel membrane free electrolyser technology that is able […]Read More
