Which parts of the world will be able to produce the cheapest green hydrogen in the long run?

Colombia and Morocco make surprise appearances in Irena study’s top five

China will be the cheapest place to produce green hydrogen in the long term, followed by Chile, Morocco, Colombia and Australia, in an “optimistic” scenario, according to analysis from the International Renewable Energy Agency (Irena).

Chinese producers could be delivering green hydrogen at a levelised cost (LCOH) of just over $0.65 per kg by 2050, with Chile only marginally behind.

Even in the most pessimistic cost scenario, China would be producing green H₂ at an LCOH of about $1.10/kg by mid-century, with Colombia at around $1.15/kg and Australia and Chile around $1.20/kg.

The US and Saudi Arabia, by comparison, would be able to achieve levelised costs of around $0.75-0.80 per kg in the optimistic scenario, with Saudi Arabian costs rising significantly higher than those in the US in a pessimistic scenario, due to water constraints.

This issue also affects Morocco, which according to Irena’s most optimistic cost scenario, has the potential to produce hydrogen at levelised costs comparable to Chinese production. However the agency warns of a significant level of uncertainty around Morocco’s access to water, potentially constraining production by 63%.

But in the event that producers in water-constrained areas can source water, desalination costs would add just 4% to costs, it noted.

In Irena’s pessimistic scenario, Canada sneaks into the top five, ahead of Morocco.

Significantly, many parts of the world will be producing green hydrogen at below $1 per kg by 2050 in the optimistic scenario, said Irena, with the exception of Southeast Asia, the UK, Germany, Argentina, Japan, Korea and northern Europe, among others.

Ukraine would also miss the mark, it added, a conclusion that could hold potential ramifications for the EU’s ambition to create a “hydrogen corridor” from Ukraine.

But some individual nations vying to become green hydrogen economies — particularly in sub-Saharan Africa — were not included as individual nations in the Irena analysis, potentially skewing the results.

Costs for green H₂ produced in sub-Saharan Africa would range from $1-1.50/kg and the Middle East and North Africa $1/kg to around $1.80/kg, the agency said. But Egypt, which is currently the largest hydrogen consumer in Africa, could produce green hydrogen at below $1/kg when considered on its own.

And Namibia, which has been touting its hydrogen export potential to Europeans at the World Economic Forum in Davos, is likely to be relatively expensive compared to other African nations, with costs of $1.20-1.90/kg — although this could be related to Irena labelling much of the country as “not eligible” due to water and other constraints — despite pointing out the relative low cost of desalination.

In fact, only 25 countries in total were analysed, with the remainder lumped into regional or continental entries.

Overshadowed

Colombia’s inclusion so high up in this analysis might come as a surprise. The country’s potential as a green hydrogen supplier has often been overshadowed by its more vociferous competitors – a situation President Iván Duque Márquez and energy minister Diego Mesa Puyo sought to rectify this month by addressing the inaugural GH2 Global Green Hydrogen Conference in Barcelona.

The country is targeting 3GW of dedicated electrolyser capacity by 2030, having grown its solar and wind capacity 100-fold to around 2.8 GW over the past two years.

Puyo told delegates in Barcelona that Colombia believes that local green H₂ producers can sell to domestic off-takers at prices of $1.70/kg by 2029, on the back of Colombia’s offshore wind speeds — which he claimed reach 13 metres per second — and low electricity prices.

Colombia closed an auction for onshore wind and solar in 2019 at below $30/MWh, Puyo said, adding that the country is also banking on investment-based tax incentives to bring cash into the country’s hydrogen sector.

“It may also depend on what happens with the carbon tax,” he added. “We have very small price for carbon tax at the moment, which is set to increase over the next couple of years, and that is definitely going to make green hydrogen very competitive.”
