Hub and SPOKE Model
On-the-ground solutions delivery
The core structure for delivery is a "hub and SPOKE" model, with a single centre servicing one or more SPOKEs in neighbouring locations.
We aim to create a comprehensive suite of services - delivered through specialised Centres of Excellence for Sustainable Cooling and Cold-Chains (i.e. Rwanda, Africa and Haryana, India) and regional SPOKEs - to accelerate the uptake of sustainable cooling and cold-chain in the Global South. Uniquely, it is designed to develop and transition to a self-financing, growth business model, thereby delivering long-term and sustained impact, along with the immediate wins.
Centres of Excellence
Africa
ACES is housed on a five hectare campus with an adjacent 200 hectare farm in Kigali, Rwanda. Collaborative research, new equipment testing, and the development of knowledge training programmes and robust business models takes place here.
India
To establish the CoE, the state government has allotted ca. 15 acres (6 ha.) of land within the premises of the Directorate of Horticulture (DoH) at Panchkula, Haryana. Test laboratories, demonstration facilities, a community cooling hub, training centre and incubation hub will all be available.
SPOKEs
SPOKEs showcase how solutions can be deployed in practical, real-world applications and provide on-the-ground training, capacity building, and support for farmers and their communities to;
- design sustainable community cooling and cold-chain solutions,
- develop financeable business models, through to the day-to-day operations and Post-harvest Management,
- develop a network of skilled engineers coming from the Centre of Excellence and SPOKE, to support equipment installation and maintenance.
Reference SPOKE - Kenya
The first SPecialised Outreach and Knowledge Establishment (SPOKE) is in Kenya. Kenya is the reference SPOKE through which we are designing the SPOKE programme, building the delivery team and developing the toolkits for our reference and replicate model.
The SPOKE team provides the essential enabling mechanisms, tools, technology selection, business model, governance and operational systems, and the targeted training necessary to support community leaders and the wider community. This will help establish a grassroots, community cold-chain ecosystem and integrate cold-chain into their operations.
The SPOKE programme works in three phases, taking a journey from initial community partnership scoping in Phase 0, then through Phase 1 establishing the engagement framework and support ecosystem, and finally in Phase 2 implementing the Try Before You Buy model on-the-ground and proving practical viability
As an example of the programme’s success, the Lari cooperative, our first community SPOKE in Kenya, has been able to aggregate its produce through its cold-chain and market its top-quality produce to higher-end markets.
They earn, on average, over 50% higher returns for their produce than previously.

Celebrating cooling through the Festival of Cooling. Without reliable ways of transporting food in a cooled environment, food arrives at its destination spoiled, sales are lost, and the livelihoods of farmers, fishers and other producers suffer. These stories are repeated across Rwanda and across Sub-Saharan Africa time and time again.
