Biogas holds great power generation potential

South Africa has the potential to generate upwards of 10 000 MW of power if it were to harness and capitalise on all biogas opportunities, however, the greatest challenge is not a lack of capacity but more the lack of market opportunity, says Southern African Biogas Industry Association (Sabia) chairperson Jason Gifford. Speaking during the Sabia webinar launch of its Biogas Market Position Paper, Gifford mentioned that the South African biogas industry is flourishing and holds vast potential for greener power generation.

Gas can decrease emissions in power generation

With power generation being accountable for 41% of current global carbon emissions, which amount to about 33.7 Gt/y of carbon dioxide (CO2), multinational conglomerate General Electric Company (GE) believes that gas can play a vital role in decreasing carbon emissions. “Gas burns at less than half the CO2 of coal and GE seeks to convert its gas technologies to low or near-zero carbon emissions using hydrogen and carbon capture and sequestration technologies,” says GE Gas Power emerging technologies director Dr Jeffrey Goldmeer.

Bidding for renewables finally opens as powership-heavy ‘emergency’ projects are unveiled

Mineral Resources and Energy Minister Gwede Mantashe released the names of the eight preferred bidders – including three powership projects – selected as part of government’s 2 000-MW ‘emergency’ procurement programme and also launched the much-anticipated fifth bid window (BW5) for the procurement of new wind and solar. However, he resisted growing calls for a raising of the licence-exemption threshold for distributed projects at mines, smelters, factories and farms from 1 MW to 50 MW, indicating instead that the cap would be increased to only 10 MW. This despite arguments that a liberalisation of South Africa’s convoluted licencing regime was the cheapest and quickest way to unlock at least 5 000 MW of new capacity within five years.

34 South African cities join global move towards setting renewables targets

A new international report shows that 34 South African cities, in which some 15.3-million people live and work, had adopted renewable-energy targets and/or policies by the end of 2020, with Cape Town, eThekwini, Johannesburg and Tshwane having also announced official net-zero targets. The ‘Renewables in Cities Global Status Report’, published by REN21 on March 18, also shows that these South African cities are part of an international trend, with more than 1 300 cities globally having also adopted renewable-energy targets and/or policies by the end of last year.

AfDB funds $530m Angola electricity project to expand renewable energy, regional connectivity

Development finance institution the African Development Bank (AfDB) has committed $530-million to finance the construction of a 343 km, 400 kV central-south transmission line that will connect the north and south transmission grids in Angola and allow for the distribution of clean energy between the two regions. The north of Angola has a surplus of more than 1 000 MW of mostly renewable power, whereas the south relies on expensive diesel generators, supported by government subsidies.

Green hydrogen could help South Africa increase its energy exports

South Africa has traditionally been a net importer of energy, but a relatively new clean technology could be pivotal in helping South Africa become an exporter and dramatically cut the country’s carbon emissions, says Rand Merchant Bank (RMB). RMB CEO James Formby says that although green hydrogen is yet to be widely adopted around the world, it is one of several potential low-carbon fuels that could take the place of today’s fossil fuels.

Western Cape names candidate municipalities to be primed for direct IPP procurement

Six Western Cape municipalities, as well as the City of Cape Town, have been named by Western Cape Finance and Economic Opportunities Minister David Maynier as candidates to participate in the first phase of the province’s Municipal Energy Resilience (MER) project. The MER initiative, which was unveiled in 2020, has been established to enable the development of municipal energy projects in the province in line with recent changes to the country’s energy regulations, empowering municipalities to purchase energy directly from independent power producers (IPPs) and/or to develop their own generation facilities.
