Pump systems optimised through energy-saving assessments

With international studies showing that pump systems account for more than 20% of global electrical energy demand, the National Cleaner Production Centre South Africa (NCPC-SA) has worked with more than 450 companies during the past decade, under its flagship Industrial Energy Efficiency Project. One of the project’s offerings, which has been taken up by large energy users, is pump system optimisation (PSO). Pumps comprise a large and integral part of almost every subsector of industry in South Africa and, therefore, provide great opportunity for energy savings, according to the NCPC-SA.

Hydro project set to boost green credentials of giant DRC copper complex

While Kamoa Copper, in the Democratic Republic of Congo (DRC), is on track to become the second-largest copper mining complex globally, and the biggest in Africa, it is also poised to be among the greenest of copper mines. This is largely on the back of the project being completely powered by hydroelectricity, and the intention to implement a switchover to electric mining vehicles, Kamoa Copper CEO Mark Farren tells Engineering News & Mining Weekly.

Eskom to implement power cuts to replenish reserves

South Africa’s struggling state power utility Eskom said it would implement scheduled power cuts from Thursday evening to replenish emergency generation reserves. The “stage 2” power cuts, which requires up to 2,000 megawatts of capacity to be shed from the national grid, will be implemented from 9 p.m. local time on Thursday until 5 a.m. on Friday, and again from Friday at 9 p.m. until Saturday at 5 a.m.

PCC’s Olver sees updating IRP to exclude new coal as key policy priority

Presidential Climate Commission (PCC) executive director Dr Crispian Olver says updating South Africa’s energy policy to exclude any new coal capacity to 2030 and beyond, while increasing the allocation for renewable energy to at least 30 GW by the end of the decade should be key priorities for the coming 24 months. In a presentation delivered at the 2021 edition of Windaba, in Cape Town, Olver said that research had affirmed that a renewables-dominant electricity system would be the lowest-cost for South Africa, as well as the fact that the costs associated with increasing the country’s decarbonisation ambition were not as high as initially expected.

Ramaphosa moots possible hydrogen partnership with Namibia as he punts Boegoebaai export hub

President Cyril Ramaphosa says South Africa stands ready to be a major exporter of green hydrogen and has described the special economic zone (SEZ) proposed for development at Boegoebaai, in the Northern Cape, as a major step towards realising the country’s potential to be a global leader in green hydrogen and derivative products, such as power fuels. In an address to the second Sustainable Infrastructure Development Symposium, which took place as a hybrid event in Sandton on Thursday, Ramaphosa described green energy more generally as one of the “new frontiers of infrastructure development”.

Tesla’s gigafactory electrifies California-Germany culture clash

With final approval for its German factory potentially just weeks away, Tesla’s Elon Musk will make an appearance in the tiny town of Gruenheide this Saturday to host a county fair. Despite pandemic-related curbs limiting gatherings in Germany to under 5 000 people, Tesla applied for – and got – a permit to have 9 000 at the Oct. 9 ‘Giga-Fest’, after local authorities agreed the event would be COVID safe.

South Africa should not rush move away from coal, minister says

South Africa must manage its transition away from coal-fired power generation systematically and not rush a switch to renewable energy sources, Mining and Energy Minister Gwede Mantashe said on Thursday. “I am not saying coal for ever, … I am saying let’s manage our transition step by step rather than being emotional,” Mantashe told a mining conference, when asked how China’s pledge to not build new coal power stations abroad would affect South Africa.

Mature local wind energy industry ready to deliver 14.4 GW of capacity over the next decade

The tenth yearly wind industry conference Windaba, which opened on October 7, marks a decade of wind power in South Africa and the industry has matured to the point that it is ready and able to build an additional 14.4 GW of wind power capacity over the next decade, says industry organisation South African Wind Energy Association (SAWEA) chairperson Mercia Grimbeek. “Our celebration of ten years of wind energy in South Africa brings us to a confluence as our industry stands ready for the next decade of growth that will be characterised as a resurgence and a period of exponential growth in our country’s energy narrative,” she notes.
