Publication of Wastewater Treatment Efficiency Gains

 

Oxygen trials yielding energy and efficiency gains at Northern Ireland Water
project

 

CPH2, the UK-based green hydrogen technology and manufacturing company that
has developed the IP-protected Membrane-Free Electrolyser ("MFE"), is pleased
to note the publication from specialist engineering company, Lagan MEICA
("Lagan"), on the benefits witnessed at Northern Ireland Water's ("NIW") site
of using high purity oxygen, as part of a project which incorporates an MFE
electrolyser in wastewater treatment.

 

CPH2's MFE technology is currently operating at NIW's Duncrue Street site in
Belfast, producing green hydrogen and oxygen. By using the oxygen-enriched air
in secondary treatment, Lagan has observed a 15% reduction in aeration time, a
31% increase in ammonia removal, and a 13% reduction in energy consumption,
amongst other efficiency gains. These efficiency gains translate into
increased capacity and reduced sludge transportation and disposal. Upon
scaling this process is expected to result in a significant reduction in cost
for NI Water, whilst also producing a valuable fuel cell-grade hydrogen
byproduct available for sale.

 

Lagan's publication of the energy and efficiency gains at NIW's site has
identified and quantified the benefits of oxygen-enriched aeration into
secondary wastewater treatment processes using oxygen produced from green
hydrogen electrolysis. The publication shows the potential benefits of using
CPH2's technology at waste treatment plants, which can be replicated across
multiple sites around the world.

 

The commercial benefits of CPH2's technology at NIW's site will be further
enhanced by the commercialisation of the fuel cell grade green hydrogen being
produced at site. Being the first and only production of pure hydrogen and
oxygen generated reliably by an electrolyser at scale in Northern Ireland,
there are a number of potential uses available which all have significant
effects in reducing carbon emissions for industry and transport in the area.

 

 

Jon Duffy, CEO of Clean Power Hydrogen commented:

 

"It is extremely pleasing to read Lagan MEICA's report detailing the
significant efficiencies brought about to Northern Ireland Water's treatment
plant through the use of oxygen, such as that produced through our MFE
technology. To have our technology in the field creating tangible efficiencies
in a key target market for CPH2 is what we have been working tirelessly to
achieve, and the results show the true potential in rolling out our technology
in similar processes around the UK and beyond. We look forward to continuing
to work together with our partners in harnessing the gains and efficiencies
which our technology can create."

 

Commenting on the report Neil McKenzie, Director at Lagan MEICA JV, said:

 

"This cutting-edge scheme is investigating the benefits of supplying oxygen
from an electrolyser to wastewater treatment sites. By harnessing green power
from the grid during periods of wind curtailment, we aim to produce oxygen,
reduce energy consumption, lower greenhouse gas emissions, and explore the
potential of using hydrogen fuel cells to power the plant. Lagan MEICA is
delighted to work in partnership with NI Water as part of its green hydrogen
and oxygen journey towards a net zero utility environment."
