In 2026, the primary threat to the African agricultural economy isn’t just production—it is Post-Harvest Loss. Estimates suggest that up to 40% of food produced in the region never reaches the consumer due to “broken” cold chains. Cold Solutions Kiambu (SEZ) Limited is engineering the fix.
With a newly secured $19 million debt investment from the Mirova Gigaton Fund, Cold Solutions is scaling its flagship infrastructure in Tatu City, Kiambu. This move positions the company as the “Sovereign Shield” for perishable goods, ensuring that farmers’ incomes are protected and vaccine efficacy is maintained across the East African corridor.
The Kiambu facility is a benchmark for Energy-Efficient Warehousing. Unlike legacy cold storage that relies heavily on unstable national grids and diesel generators, Cold Solutions has built a “Circular Energy” model.
-
Solar Integration: The facility features a massive rooftop solar system that covers approximately 30% of its energy requirements.
-
Ammonia Refrigerants: The system uses natural ammonia-based refrigerants, which have zero global warming potential (GWP), making it a “Climate-First” industrial asset.
-
Storage Capacity: The Tatu City hub operates with approximately 15,000 pallet positions, providing the high-density storage required for massive agricultural and pharmaceutical throughput.
The $19 million infusion is designed to accelerate the deployment of cold chain assets that serve as the backbone of regional resilience.
-
Agricultural Preservation: By minimizing spoilage, Cold Solutions directly enhances the income of smallholder farmers and large-scale producers, aligning with SDG 2 (Zero Hunger).
-
Pharmaceutical Integrity: The facility is engineered to handle temperature-sensitive vaccines and medications, a critical component of East Africa’s healthcare infrastructure in 2026.
-
Market Expansion: This financing allows Cold Solutions to “ramp up” its operations, moving from a single flagship node to a regional network of climate-resilient hubs.
The involvement of Mirova, an affiliate of Natixis Investment Managers, signals a shift in global capital toward Impact-Driven Debt.
-
The Gigaton Fund: This fund is specifically designed to accelerate transformative climate solutions in emerging markets. The investment in Cold Solutions is its “Proof of Concept” for scalable, clean-powered infrastructure in Africa.
-
Institutional Backing: The deal was facilitated in partnership with ARCH Emerging Markets Partners Limited, further solidifying the “Defence-of-Supply” strategy we are seeing across the continent’s infrastructure sector.

The “Index” Take: In 2026, the most valuable infrastructure is the kind that works when the power goes out. By combining $19 million in capital with 15,000 pallets and rooftop solar, Cold Solutions is building the “Deep Freeze” of African sovereignty. For Mirova, this isn’t just an investment in a warehouse; it’s a hedge against the climate-driven instability of food and health systems.
