Ten energy innovations taking hold in Africa
Compiled by Alice Mugo
1. Pay-as-you-go (PAYG) Solar Systems
- Key Players: M-KOPA (Kenya), PEG Africa (Ghana), Sun King (formerly Greenlight Planet)
- What’s innovative: These companies allow households, often off-grid, to buy solar home systems through micro‑payments via mobile money. This model dramatically lowers the upfront cost barrier, leapfrogs traditional utilities, and scales rapidly.
- Impact: Millions of African homes now access electricity via clean solar, replacing kerosene lamps and diesel generators.
2. Hybrid Solar + Commercial Mini-Grids
- Key Player: Daystar Power (Nigeria)
- Innovation: Combines solar panels with battery storage and backup diesel generators to serve businesses (banks, schools, SMEs).
- Why it matters: Offers reliable, cost-effective power for businesses that previously depended on expensive or polluting generators — accelerating economic activity in under‑electrified regions.
3. Solar Tower with Thermal Storage
- Project: Khi Solar One (South Africa)
- What’s new: It’s Africa’s first solar power tower plant, using concentrated solar power (CSP) to generate heat, which is then stored and used to produce electricity 24/7.
- Significance: Breaks the intermittency barrier by making solar power more dispatchable, bridging renewables with continuous baseload capability.
4. Prepaid Solar Electricity
- Company: WiSolar (South Africa, Nigeria)
- Innovation: Users buy solar electricity on a prepaid model via a mobile app.
- Impact: Democratises access, especially for lower-income households; reduces reliance on polluting fuel sources.
5. Waste‑to‑Energy Plant
- Project: Reppie Waste-to‑Energy (Addis Ababa, Ethiopia)
- Innovation: Converts municipal solid waste into electricity (25 MW plant) — addressing both energy needs and waste management.
- Why it’s important: Tackles environmental and social challenges simultaneously, turning urban trash into a clean power source.
6. Green Hydrogen Development
- Initiatives: Projects in Mauritania, Namibia, Egypt, South Africa.
- Tech: Use of renewable‑powered electrolysers (solar, wind) to produce green hydrogen.
- Significance: Positions Africa as a global hydrogen hub; could decarbonize heavy industries and fuel future export markets.
7. Pan‑African Hydrogen Alliance
- Organization: African Hydrogen Partnership (AHP)
- Mission: Facilitate research, investment, and collaboration on green and natural hydrogen across African nations.
- Why it’s strategic: Building institutional capacity and policy frameworks now can unlock long-term hydrogen economies on the continent.
8. Advanced Energy System Modelling
- Tool: PyPSA‑Earth open energy system model applied to Africa
- Innovation: High‑resolution, open-source modelling of generation, storage, and grid infrastructure — tailored for African geographies.
- Impact: Enables governments, utilities, and developers to plan more efficiently, optimize investments, and simulate future energy transitions with transparency.
9. Battery‑Life Extension Via Smart Charging
- Research: Forecast-based charging strategy for lithium-ion batteries in standalone PV systems in Sub-Saharan Africa
- Innovation: Charging logic that keeps battery state-of-charge low when possible (based on weather forecasts), to slow degradation.
- Why it matters: Extends lifespan of one of the costliest components in off-grid solar systems — making them more economically and environmentally sustainable.
10. Smart Metering for Micro-Utilities
- Startup: Chanels Innovations (Rwanda) — from the 4th Energy Camp.
- Innovation: AI‑ready, multichannel energy metering systems tailored for small scale (micro) utilities.
- Impact: Enables more efficient, data-driven management of distributed energy resources; helps micro-grid operators optimize billing, capacity, and maintenance.
