Eskom warns of elevated diesel use as system outlook remains precarious

State-owned electricity group Eskom is warning that its use of the country’s diesel-fuelled open cycle gas turbines (OCGTs) is set to remain elevated in the coming months as the utility seeks to avoid load-shedding in a context of rising planned maintenance and the ongoing risk of unplanned breakdowns. Eskom has already spent R5.5-billion for the year-to-date to run its own OCGT plants and a further R3-billion to purchase electricity from the private Avon and Dedisa plants, as the energy availability factor (EAF) from its coal fleet slumped to 62.9% against a target of 70%.

South Africa’s emergency power process nears another deadline

South Africa has made faltering progress toward implementing plans announced more than two years ago to procure additional power needed to swiftly address crippling energy shortages. The Department of Mineral Resources and Energy first issued a request for information from potential electricity suppliers in December 2019. A year later it listed 28 interested bidders, and in 2021 it chose the winners of contracts to generate about 2,000 megawatts of capacity under its so-called Risk Mitigation Independent Power Producer Procurement Programme.

Bitcoin-paying solar power company plans African expansion

Sun Exchange, a South African firm that crowd-sources funds for solar panels and leases them to customers, plans to expand to other countries on the continent. The company, backed by a group part-owned by billionaire Patrice Motsepe’s African Rainbow Capital Investments Ltd., raised $1.4 million for a solar panel and battery-storage project at a Zimbabwean fruit and berry producer, in what it says is the biggest crowd-funded project in Africa.

Green primary iron could help South Africa offset fall in coal export revenues – study

Producing carbon-free primary iron in South Africa using green hydrogen direct reduced iron (GHDRI) technology could create a new globally competitive green export industry that could help offset the losses associated with the eventual decline in coal exports, a new study shows. Such exports would also reduce the cost of decarbonising global steel production, owing to the relative cost advantages of producing renewable energy in South Africa and, therefore, green hydrogen. Producing GHDRI involves a new type of furnace that uses hydrogen for the direct reduction of the iron-ore, as opposed to the traditional route that uses coke.

Agreement inked to develop hydrogen recycling of end-of-life wind turbine magnets

Magnet metal and rare earths miner Pensana has signed a cooperation agreement with oil, gas and wind power company Equinor, forming a working group to share technical and commercial information to develop a low-energy method for recycling end-of-life magnets at Pensana’s rare earths hub in the Saltend Chemical Park, in the UK. Pensana chairperson Paul Atherley says the agreement relates to processing end-of-life magnets from wind turbine nacelles using properties found in hydrogen as a powerful reductant. Recycling permanent magnets using hydrogen not as a fuel, but as a reductant, while also benefitting from the decarbonised power supply within Saltend, offers the parties a clean alternative that uses 88% less energy than virgin magnet manufacture.

McKinsey pegs the price tag of a livable climate at $9.2tr a year

A new analysis from McKinsey & Co. estimates that the investment, in new infrastructure and systems, needed to meet international climate goals could be $9.2-trillion a year through 2050. That’s at least $3.5-trillion more a year than the world is currently laying out for both low-carbon and fossil-fuel infrastructure and changes in how people use land. McKinsey analysts wanted a sense of how much investment would be necessary, and what behavioral changes would be required, to slash the impact …

Natural gas, electricity price volatility and inflation the result of natural gas crisis

Natural gas and electricity prices have spiked to record highs, most notably in Europe and some major Asian markets, causing potentially significant economic impacts and volatility in gas and electricity markets, driven by turmoil in natural gas markets, says intergovernmental organisation International Energy Agency (IEA) executive director Dr Fatih Birol. A range of issues are affecting the natural gas sector, including last year’s exceptionally rapid global economic rebound, outages and maintenance of key gas infrastructure and a lack of sufficient supply from Russia, which are driving broader energy market turbulence in Europe.
