JOHANNESBURG, Nov 17 (Reuters) - South Africa could produce over five million tonnes of green hydrogen a year by 2040, according to a plan it presented at the U.N. climate summit in Egypt that aims to catapult the world's 13th biggest polluter into a greener future.
The plan envisages reaching annual production of 10 million tonnes by 2050 and creating a local market worth $20 billion, employing around 50,000 people.
Green hydrogen, made by using renewable energy to split water into hydrogen and oxygen, is viewed as vital in the world's shift away from fossil fuels and part of a three-pronged approach South Africa is taking to tackle its carbon emissions.
The other two are substituting its ageing coal plants with solar and wind power and kick-starting an electric vehicle revolution.
But for a country still squabbling over when to retire coal plants, it is a mammoth task.
"The political situation in South Africa is on a kind of a knife edge right now ... We really need to get some policy, regulatory and planning certainty," Chris Yelland, managing director and energy analyst at EE Business Intelligence, told Reuters TV.
The government estimates that realising its green hydrogen goals would require up to 100 gigawatts (GW) of additional solar or wind power capacity, and investing close to $133 billion.
According to Boston Consultancy Group, South Africa will need to set up 6-7 GW of renewable capacity per year for the next two decades, compared with the 6 GW it has managed in total since 2011.
"It might very well be feasible ... our renewable resources are world class: solar radiation, wind," said Margo-Ann Werner, environmental law director at law firm Cliffe Dekker Hofmeyr.
"It really is about the (regulatory) environment: ... electricity generation, pipelines for distribution, converting port facilities; all of that can be dealt with if we really commit."
