A current digital media roundtable organised by GE Gas Power centered on ‘Pathways to Faster Decarbonisation with Gas and Renewables’.
The energy sector accounts for as much as 41% of worldwide carbon dioxide emissions at present, with Africa contributing about 2-Three%.
In parallel, there are nonetheless over 580 million folks on the continent who don’t have entry to dependable power and the demand for electrical energy is anticipated to proceed to develop as populations improve, industrialisation ambitions develop and urbanisation continues to gasoline the necessity for extra energy.

Europe should ramp up renewables argues Eurelectric
To tackle sustainability considerations, the world is transitioning in the direction of a decrease carbon power combine at a tempo unseen earlier than. This is mirrored within the whole world worth of power transition funding – together with spend on new renewable power capability, electrical automobiles and related charging infrastructure, power storage applied sciences, and extra – reaching over $500 billion for the primary time in 2020. This was a rise of 9% over the earlier yr, regardless of the financial impression of the COVID-19 pandemic.
However, whereas renewables are rising quickly, will increase usually are not occurring quick sufficient, and they’re nonetheless projected to supply lower than half of the worldwide electrical energy provide by 2040.
“As sub-Saharan Africa balances the necessity for extra entry to energy with the drive for transition to cleaner power sources, the accelerated and strategic deployment of renewable and gasoline energy collectively can ship a no-regrets path to make substantive reductions in emissions rapidly, whereas delivering reliable, inexpensive energy,” says Elisee Sezan, CEO of GE Gas Power Sub-Saharan Africa.
A current white paper by GE titled Accelerated Growth of Renewables and Gas Power Can Rapidly Change the Trajectory on Climate Change outlines how gasoline energy can complement renewables to supply decarbonisation at scale within the near-term, with pathways to close zero in the long run, whereas offering inexpensive and dependable baseload energy.
The complementary attributes of renewables and gasoline energy
Today, we’re seeing international locations throughout sub-Saharan Africa (SSA) decide to growing the share of renewable power of their combine and to decarbonise their economies. South Africa not too long ago introduced three new renewable procurement rounds totaling 6,800MW all through 2021.
Nigeria’s National Renewable Energy and Energy Efficiency Policy goals so as to add 10GW of grid-connected renewable power by 2030. Kenya, Senegal, Ghana and Angola have related ambitions. Gas energy provides distinct benefits in supporting this development of renewable power all through the area.
Gas is more and more plentiful, out there, and inexpensive, and anticipated to turn out to be much more so within the years forward, providing international locations comparatively low-cost energy on demand. It provides the cleanest technique of energy manufacturing amongst all conventional fossil fuels, with as little as lower than half the carbon dioxide emissions of coal. Additionally, gasoline provides pathways to future conversion to low or close to zero carbon with hydrogen and carbon seize, utilisation, and sequestration (CCUS) applied sciences.
Gas additionally gives reliable, dispatchable capability that’s out there whatever the time of day, season, or climate; that is essential for grid stability as very excessive renewables penetration can result in system instability. Gas vegetation can compensate for lengthy gaps in renewable manufacturing in ways in which at present’s battery storage know-how can not. The latter can normally be used for short-term (usually <eight hours) storage of renewable power, whereas gasoline is economical for longer length peaking wants. Furthermore, gasoline energy vegetation are versatile, with the power to start out rapidly, ramp energy up or down, and turndown to very low output ranges, to allow them to present inexpensive, dispatchable energy that may fill the availability/demand hole as and when wanted.
Gas energy vegetation have a considerably smaller bodily footprint than wind and solar energy vegetation, enabling…
