Abstract 1

Abbreviations 5

1. Introduction 6

2. The role of lead in off-grid electrification 10

2.1. Low and unreliable electricity access constrains sub-Saharan Africa's development 10

2.2. Expanding electricity access is a significant political priority for African citizens, governments, and their development partners 12

2.3. Rapid electrification will rely heavily on off-grid solutions 14

2.4. Off-grid solar systems require battery storage-with lead-acid batteries still dominating the market 15

3. Addressing safety risks from lead acid batteries 19

3.1. Without appropriate EoL management, lead acid batteries create severe health and safety risks 19

3.2. Actual recycling practices in Sub-Saharan Africa are enormously polluting and unsafe 21

3.3. Economic incentives cut against safe recycling 22

4. Market deep-dive-the off-grid solar industry 23

4.1. The supply of off-grid solar products is vast, unorganized, diverse, and bifurcated 23

4.2. Demand is shaped by macroeconomic factors, price reductions, and development commitments 25

4.3. The off-grid solar sector includes diverse stakeholders and interest groups 26

5. Discussion and conclusion 27
