Coal remains king as Sasol scrambles to run on gas and hydrogen in SA

South African energy company Sasol aims to become one of the largest buyers of renewable energy in Africa, but is currently reliant on fossil fuels. The firm, which is the country’s second largest emitter, has committed to reaching net-zero by 2050 but has been criticised for vagueness and unrealistic goals. Sasol plans to cut emissions by 30% by 2030 by replacing 25% of its 40 million tons of coal consumption each year with natural gas. It is doubling down on exploration of its own fields in Mozambique and may import liquefied natural gas from 2025. Sasol is also exploring a green hydrogen project on South Africa’s west coast to replace natural gas. Read more below.

South Africa’s second-biggest emitter aims to be among the continent’s biggest buyers of renewable energy — but for now Sasol Ltd. remains firmly tied to fossil fuels.

The company that made its name producing synthetic fuel and chemicals from coal, aims to reach net zero by 2050. That plan has been criticized as vague by activists and unrealistic by some analysts. OPEC’s recent surprise production cut may also spur some energy companies to revisit their green goals in light of higher oil prices, which largely determine the value of Sasol’s products.

Fleetwood Grobler

Curbing emissions will be an especially heavy lift for Sasol — its biggest plant produces more greenhouse gas than the global operations of oil companies BP Plc or Marathon Petroleum Corp. Chief Executive Officer Fleetwood Grobler said the company is committed to its green future; the company just needs profitability to get there.

That starts with the dirtiest fossil fuel, which has been the company’s lifeblood since it was founded in 1950 and what has made its Secunda plant in central South Africa the world’s single most-polluting site. 

“We’ve got a focus on coal quality that’s impacting our operations,” he said in an interview at the company’s headquarters in Johannesburg. Sasol has exhausted the richest deposits at its mines and what’s left doesn’t work as well in processes that convert the mineral into fuel, he said. “We are working hard to remediate that.”

Despite the recent uptick, volatility in the oil price also has Grobler concerned, particularly if crude prices fall toward $40 a barrel. “I would be really worried at that point,” he said.

Coal for Gas

Sasol’s strategy to cut emissions by 30% by 2030 also involves displacing one fossil fuel with another. Reducing the 40 million tons of coal it mainly uses to make fuel each year by a quarter will mean finding enough natural gas, which is more efficient and creates lower emissions, Grobler said. 

Analysts are skeptical. “We still struggle to see how more gas makes long-term sense,” JPMorgan Chase & Co. said in a November research note. The US lender also found that investors, especially in Europe, are wary of the stock. “An increasing number find it difficult to justify owning Sasol as climate concerns mount,” it said.

Grobler said that while the company arrived late to the green transition — it only came up with a plan around early 2021 — investors will be able to see its progress over the next five years. 

“What shareholders are looking for is to see how we remain profitable, how do we remain committed to our outcomes of greenhouse gas reduction targets and how do we remain relevant beyond that and still be a profitable company,” he said. 

Enough Gas

Sasol’s cheapest source of natural gas is the company’s own fields in Mozambique that bring the fuel to its operations through the 537-mile Rompco pipeline. The company is spending $1 billion to find more in the region because it’s “concerned” about finding enough to replace coal beyond 2028, Grobler said. “We are doubling down on our exploration in Mozambique,” he said.

Otherwise the company can fall back on imports of liquefied natural gas, a decision Sasol will need to make from 2025, allowing three years to prepare for the supply, he said. Import terminals capable of unloading the fuel in Maputo and a potential South African project in Richards Bay are still in planning phases.

Sasol’s largest plant, the Secunda complex about 130 kilometers (209 miles) from Johannesburg — which produces more climate-warming gases than either Portugal or Norway — will need to more than double the proportion of gas used from 7%, according to Grobler.

Still, activists have been withering about Sasol’s approach. 

“The lack of adequate details, accountability measures and incentives means that Sasol does not have a feasible, measurable plan for it to achieve its emission reduction targets,” said Tracey Davies, director of Just Share, a Cape Town-based activist group that’s tried to enlist shareholders in scrutinizing Sasol’s plans.

As Sasol transforms, it will also pay a growing fee for the carbon it emits. Grobler points out that South Africa is the only place where the company, which also operates in the US and Europe, pays a carbon tax. Chief Financial Officer Hanre Rossouw has warned that the levies could potentially cut into the business and its green transition plans.  

Green Hydrogen

The use of renewables for electricity will be another major element of the company reaching its 2030 target. Sasol has signed agreements with developers, including Air Liquide SA and TotalEnergies SE, for almost half of the capacity it will need to meet its 1.2-gigawatt renewable goal. 

Adding more renewables to the mix will be difficult. South Africa has become overwhelmed by record power outages, while its program to buy electricity from private clean energy projects has been slowed by a lack of grid connections. State-owned utility Eskom Holdings SOC Ltd. governs the process that determines which stations get plugged in, Grobler said. 

Sasol is also exploring a green hydrogen project on South Africa’s west coast, which it hopes will provide an even cleaner fuel to someday replace natural gas. The Boegoebaai project would include a port developed by the struggling state-owned port and rail company Transnet.

It’s another plank in Sasol’s complicated green transition plans that will require even more renewable energy.

The Boegoebaai project is ending a pre-feasibility study and is “a work in progress,” Grobler said, declining to estimate the cost of the green hydrogen plans. “That is still in very early phases.”
