Hydrogen trade potential in African pipeline infrastructure

Hydrogen trade in Africa doesn’t necessarily demand a complete new infrastructure. There’s exciting potential for the proposed hydrogen economy from Africa’s existing and planned pipeline infrastructure, currently used for the transmission of natural gas, oil and other chemical products. Large parts of this infrastructure could be used for hydrogen transport too. This could reduce set-up costs and help establish a large-scale hydrogen economy in Africa more quickly.


Economic potential for European-African collaboration

Using existing pipelines would support green, collaborative technological and economic development in Europe as well as Africa. The topic of using existing natural gas pipeline infrastructure in Europe to transmit hydrogen blends or pure hydrogen gas with no natural gas is getting more and more attention. Take a look at the many articles and studies on producing hydrogen in North Africa and exporting it via existing pipelines to Europe in the links below.


An end to African dependency on fossil fuel imports?

Internal African hydrogen production, storage and trading could make fossil fuel imports obsolete. Most existing gas and oil pipelines extend to harbours, offering the possibility of trading hydrogen overseas using tankers. Temporary local shortages or surpluses of hydrogen could be addressed by internal African hydrogen trade via pipelines and tankers or overseas import and export from other continents.


Hydrogen transmission methods

There are many proven and pre-existing ways to store and transport hydrogen. These include compressed and liquid hydrogen (CH2 and LH2), liquid organic hydrogen carriers (LOHC), methylcyclohexanes (MCH) and ammonia (NH3). They each have different economic, physical and integration properties - there is a need and market for all of them.

Studies indicate that only minor modifications are needed to natural gas pipelines in order to use them for hydrogen only. We’re not aware of any existing studies on reuse of oil and other chemical product pipelines for LOHCs/MCHs or ammonia (NH3) and we would welcome research and insight into the specific potential.


A diverse pipeline model?

Existing and future pipelines can be grouped into three categories:

- Natural gas pipelines

conversion to carry hydrogen gas - hydrogen blends or pure hydrogen.

- Oil pipelines

conversion to carry liquid organic hydrogen (LOHC) or methylcyclohexanes (MCH)

- Chemical products pipelines (e.g. gasoline, propane, heating oil and ethylene)

conversion to carry liquid organic hydrogen (LOHC), methylcyclohexanes (MCH) or anhydrous or liquid ammonia.


Connections beyond pipelines

In remote areas with suitable, low cost land available, Power to Hydrogen (P2H) installations located close to the pipelines could feed into them and supply cities and industries. These could carry hydrogen in the form of gas, liquid ammonia or liquid organic hydrogen (LOHC).

The map below shows the location of the 3 major pipeline types on the African continent, including some connections to Europe. We have included existing pipelines, future planned pipelines and those under consideration for feasibility.
