Why Electrolysis

Achieving Net-Zero

Electrolyzer Technology

As defined by the UN (https://www.un.org/en/climatechange/net-zero-coalition), a net-zero facility is an aspirational target accomplished by progressively identifying and eliminating Scope 1, 2 and 3 GHG emissions (https://ghgprotocol.org/) (see below).

To meet this critical goal IEPS has chosen to use Proton Exchange Membrane (PEM) electrolyzers for converting water into 99.9% pure H2 and O2.

PEM electrolyzers are a proven, reliable technology and in addition to producing two marketable products have several distinct operational and environmental advantages. These include the ability to accommodate frequent starts and stops and the ability to convert renewable power into a more readily storable form of energy.

Scope 1 Emissions

The almost total absence of Scope1 GHG emissions is another major advantage of electrolyzers over other H2 generation technologies.

The technology itself produces no GHG emissions and the few remaining Scope 1 GHG emissions created by the need to compress and transport the H2 to market can be easily addressed by using electric compressors and moving to hydrogen fueled trucks, respectively.

For a more complete description of the merits of the technology, see: https://www.siemens-energy.com/global/en/offerings/renewable-energy/hydrogen-solutions.html.

Scope 2 and Scope 3 Emissions

In achieving net-zero, Scope 2 GHG emissions from the electricity used to power the electrolyzers and residual Scope 3 (indirect) emissions are expected to be the predominant GHG emissions sources associated with the Kitsim H2 Project.

Scope 2 GHG emissions will be avoided/offset by either buying electricity from Alberta’s numerous renewable power producers and/or by purchasing Renewable Energy Credits (RECs).

Any residual Scope 3 emissions will be offset either through contracting practices and/or by using the RECs generated by the Project.
