One-line solution summary:
A solar powered Cold Storage Facility that provides both cooling and electricity to viable livestock markets in East & Southern Africa
Pitch your solution.
37% of land resources within Kenya are owned and managed by pastoralists yet their economies only contribute to 12% of the nation’s GDP. Northern Kenya especially faces this challenge due to its inability to process raw by-products into commercially marketable entities.
Prime Organic Beef consumer trends are emerging due to their more efficient approach in terms of land-use, animal welfare, and socio-climatic impacts. Pastoralists could capitalize on higher valued international city markets by supplying an ever-growing demand for sustainable protein.
The project idea addresses the expansion of off-grid electrification with an aim to assess whether cold storage facilities for meat and dairy preservation is an appropriate, beneficial and financially viable productive application especially for semi-arid economies.
What specific problem are you solving?
With Africa’s population projected to more than double by the middle of the century to 2.5bn and GDP per capita on the continent expected to continue rising, meat consumption will become affordable to millions of Africans for the first time. The United Nations Food and Agriculture Organisation (FAO) estimates that the consumption of beef and pork on the continent will increase 200% between 2015 and 2050, while poultry consumption will grow by 211%.
The rapid growth of meat consumption in Africa will provide attractive opportunities for investors, but making storage more efficient, protecting the environment and improving smallholder livelihoods poses quite a challenge. For Africa’s policymakers, the question will be how to nurture a shift to more efficient modes of production to meet demand and encourage exports.
Recognising the importance of pastoralists within Africa – Approx. 99% of Nigeria’s cattle are managed by herders- can pave way to allocation of technology and production practices that would allow the domestic market to supply consumer demand for beef over time without resulting to emulating capital intensive imports. Experts argue that even a system as 'unproductive' as nomadic herding could play a rejuvenated part in the continent’s livestock industry, given the right support.
What is your solution?
The project idea addresses the expansion of off-grid electrification with an aim to assess whether cold storage facilities for meat & dairy preservation is an appropriate, beneficial and financially viable productive application for semi-arid livestock economies.
The project is designed to be a result-based implementation that entails 2 setups;
First; involve a solution that can eliminate barriers that come with technologies that have the potential to enable viable commercial ecosystems within a remote community. This should be achieved through a 15kWp off-grid mini-grid electrification system that would connect 1,050 consumers within 120 connections rolling out a provision of up to 99.01kWh/day
Secondly; provide access to a 40ft Cold Storage Facility that would solve the largest challenge that comes with meat and dairy preservation which is Post-Slaughter Food Loss by providing Cooling as a Service where pastoralists would be able to chill over 3,000 tons of animal produce annually within a maintained temp. between -0.9 to 2 degrees Celsius.
The performance design of our hybrid systems consider energy-efficient, zero-emission strategies that can keep remotely operated technology optimal within relatively warmer communities. Our sensing and IoT controls will allow easy monitoring control, reduced operation oversight and lower OPEX cost.
Who does your solution serve, and in what ways will the solution impact their lives?
Our target users are pastoralist centers that can adopt Solar Powered Communal Refrigeration to aggregate and cool their meat & dairy produce efficiently.
The selected target site is Merille Centre, a secondary market that is fed from five local Laisamis producers within Marsabit county, Kenya. The centre ultimately supplies meat and dairy within terminal markets in Nairobi, Isiolo and Meru. Merille centre operates on a weekly basis with volumes of trade averaging 6,700 goats/month with an informal monthly turnover to KES 10m. Goat trading especially offers potential for profits of 22,500 Ksh/month which is enough to meet minimum food expenditure and investment in health, education & livelihood.
Pastoralism has a unique ability to convert scarce natural resources into meat, milk, income, and livelihoods especially in an age where consumer trends are conscious on more efficient approaches in terms land- use, animal welfare and socio-climatic impacts.
One of the largest challenges noted in these communities is Post-Slaughter Beef loss, due to the perishable nature of livestock produce and the isolation from abattoirs with availability of storage infrastructure. Pastoralists within the Horn of Africa’s greatest need is to capitalize on supplying an ever-growing consumer demand of sustainable protein.
Which dimension of the Challenge does your solution most closely address?
Improve supply chain practices to reduce food loss, scale new business models for producer-market connections, and create low-carbon cold chains
Explain how the problem, your solution, and your solution’s target population relate to the Challenge and your selected dimension.
Most Small Holder Case studies are often conducted in Fishery or Cultivation communities as project developers assume these as the most profitable economies. Pastoralists are often neglected and fall as 'Bottom-Of-The-Pyramid' consumers regardless of their abundance in solar, land and livestock resources.
Each Cold Room we aim to introduce within a Livestock market has the potential to increase slaughter yields by more than 150% by simply keeping meat frozen. During times of drought, semiarid pastoralists watch their livestock die due to the lack of post-slaughter storage options. The technology drastically reduces food waste allowing leverage on competitive market prices.

Which of the following categories best describes your solution?
A new business model or process
Describe what makes your solution innovative.
The following gives an outlook of noted competitors, their strengths & limitation and our view on how our solution benchmarks in value.
1. Transport Refrigeration
Competitor example: eNow
This comprises of cooling mobility solutions that offer services to collect fresh produce from small holder beef farmers across trade routes linking their produce directly from ‘slaughter’ to urban abattoirs.
2. Live Animal Market
Competitor example: Garsen Livestock Market, Kenya
Probably the biggest competitor of storing meat produce in pastoralist value chains is the act of selling animals live within markets. The idea is built on the premise that livestock markets function as the main convergence points for pastoralists from different geographical areas
What Makes Our Solution Unique?
Portable Cooling trucks tend to only be available for 6hours each week per market, this cuts down on time which is essential for meat farmers, whose sole purpose of cooling their produce is to weigh out profitable markets.
Live Animal markets show a constraint on limiting processing ability i.e. 70% of urban meat consumption in Nairobi is sourced from ‘Laisami’ markets that are managed by brokers who monopolize the markets
Our solutions are fixed infrastructures that are designed based on existing permanent markets, this gives the community an ability to aggregate and create an inventory management system over long periods of time. Additionally, our technology enables small holder markets to process their raw by-products into 'packaged' commercial entities that can be sold directly to meat consumers within urban residents and tourist markets i.e. hotels.
Describe the core technology that powers your solution.
The predominant technology used for this communal off-grid project is a PV/Battery Hybrid system. The energy is to be generated from an array of 57x250 Watt (W) Direct Current (DC) Solar photovoltaic (PV) panels with a recorded 14.25kWpeak power capacity, stored by 24 Lithium-ion batteries of (900Ah x 2V) charge/discharge current with an 89% round-rip efficiency and 10,000 life-cycle capacity. The solar panels will be backed up by an SMA Tripower 15000TL inverter while the batteries to have 3-SMA Sunny Island 8.0H inverters, each with AC output capacity.
The performance design of our cooling systems consider;
1. IoT for Payment & Monitoring- Micro financing is a large feature of our solution. The Pay-As-You-Store service will enable remote micro-payment from vendors through mobile money systems (which is quite rampant in Kenya via MPesa).
2. Roofing designs set up by single-ply, water-tight monolithic barriers that minimize air leaks, thermal loss, and excess moisture penetration.
3. Insulated Sandwich Panels with superb vapor barriers and hygienic finish This enables the storage of different commodities at different cooling temperatures. Our value add on efficiency is to opt for white-coated PIR cellular foams that encourage thermal insulation.
4. Flooring for the facility considers Urethane concrete floors which are thermal shock resistant and are unlikely to experience crack over time due to its exuberate finishing.
Provide evidence that this technology works.
A case study of the use and success of the proposed innovation has been proved by Rwanda's National Cooling Initiative which clearly demonstrated the ability of high-tech rural industries to take root once farmers are enabled to collectively preserve and sell high standard produce over longer time periods rather than losing half of their harvest to spoilage.
As a fast-growing nation, Rwanda understood that through energy-efficient cold chains, local food production could be achieved at the farmers level thus assuring nationwide food security. Additional impacts were seen in reduced food losses, addressed spikes in electricity demand and increased farmers income.

- Tariff engines that support an unlimited range of tariff models across various jurisdictions
- Operation & Management algorithms developed from best practices acquired within partnerships from utility scale project
What barriers currently exist for you to accomplish your goals in the next year and in the next five years?
RISK 1: Limited experience in the cold storage value chain
Since inception, Tree_Sea.mals has focused its experience on developing solar energy infrastructure, our technical expertise are more inclined towards the design and operation of the mini-grid rather than that of the cooling technology. This limitation of knowledge and technical experience to cold storage facilities might pose a high risk in operations.
RISK 2: Lack of Expert & Equipment availability in case of unexpected technical failure
Most of our target markets will be located in peri-urban / rural markets located off major highways and posts. The semi-arid terrains are rough and impassable during heavy rain seasons due to Seasonal river tributaries that terrain through the roads. This risk might cause long periods of power outages and prove fatal in emergency situations.
How do you plan to overcome these barriers?
This risk is mitigated by introducing expert advisory from credible partners interested in guiding the due diligence, design, engineering and maintenance process of the energy-efficient Cold Rooms. Examples of viable partners in Nairobi are Inspira Farms, W.Giertsen, Solar Freeze etc.
The availability of standby technicians and spare parts will be critical to long term success, as well as the involvement of users in O&M. In our mitigation, the installation of the systems would be integrated with ongoing Maintenance incentives which would be put in place to encourage community beneficiaries to become skilled workers for the company.

Why are you applying to Solve?
1. Technical Assistance
The 9 months Personalised support program will be sure to provide the organisation with committed partners to support our team with rapid prototyping, strategic advisory services, and ongoing communication and feedback to help us refine our business models and scale.
By leveraging financing partnerships with the MIT SOLVE donor funds, African developers like myself are able to accelerate efficiency within our innovation projects through rapid prototyping, strategic advisory and overall Benchmarking.
3. Inter-regional Networking
Additionally, the Finalist Pitch event in NYC would act as a great platform to showcase my findings on how international cities could access well preserved meat produce from indigenous African pastoralists and how the cohesion of both Sustainable Cities and Sustainable communities, within the global economy, could help impact Urban Climatic Action.
In which of the following areas do you most need partners or support?
Please explain in more detail here.
Tree_Sea.mals Ltd. is actively looking for non-executive and executive board members that could help in strategising scale up. If SOLVE could link us with industry players who can provide active, long-term membership within our social enterprise, this would strengthen the management team and enhance the quality of decision-making processes.
Marketing & Exposure
Digital Marketing is a fairly new media of advertising and due to the innovative aspects of our product, we wish to learn how to leverage on social media. One large issue that I hope could be solved through digital marketing is Target Audience specification. Our technology is relatively new in the market and has a high price range i.e. $10,000 - $30,000 thus a very specific clientel base spread across varying East and Southern African countries.
What organizations would you like to partner with, and how would you like to partner with them?
MIT engineering faculty
MIT is known globally for its School of Engineering and the faculties gravitation towards solving complex global problems. We would leverage this team for technical assistance in adopting the cooling structures to the hybrid mini-grids and design an efficient way for the technology to maintain optimal temperatures despite their intended semi-arid environments.
Cold Storage Manufacturer in the States
For supply of technology at manufactures rate. One of our largest challenges is finding a product manufacturer that could supply us with high quality and affordable solar powered cold rooms in the sizes 10', 20' and 40' in which we could operate optimally in warmer regions. i.e Thermoking / eNow
SOLVE African alumni
Cold Hubs is one of the few African owned infrastructure companies within the region's agricultural sector. Nnaemeka, the CEO would act as an exemplary figure to offer strategic advisory and mentorship during the 9month period.
Do you qualify for and would you like to be considered for The Andan Prize for Innovation in Refugee Inclusion?
Explain how you are qualified for this prize. How will your team use The Andan Prize for Innovation in Refugee Inclusion to advance your solution?
The team has always seen value in applying the proposed off-grid technology within remote semi-arid refugee camps across the Horn of Africa.
One specific site that is known for its valuable entrepreneurial market is Kakuma Refugee Camp, Kenya. Interviews from residents conducted in this site demonstrated great eagerness to generate businesses from livestock-related activities, especially to make up for lost income when many migrate to graze livestock or look for economic prospect elsewhere. The major challenge of SME foundations in refugee camps however is quite similar to majority of pastoralists, Access to market.
Tree_Sea.mals’ introduces portable and fixed chilled facilities that comply to international market standards and are accessible to nomadic tribes. Produce will be preserved under quality standards therefore allowing sale to higher valued products that can be exported locally and regionally at better prices. This will eventually create competition that encourages bulk processing, finishing and shipping of communal produce within Refugee camps.
Additionally, having a solar electrification generation and distribution system that can be operated in remote sites, which most Refugee camps are located, could create transformational impacts; lighting for homes and businesses, increased numeracy & literacy, cleaner indoor air for infants & elderly, better equipped health clinics, water pumping, efficient livestock vaccination and sanitation and most importantly job creation & increased income through SME creation.
Do you qualify for and would you like to be considered for the Innovation for Women Prize?
Explain how you are qualified for this prize. How will your team use the Innovation for Women Prize to advance your solution?
Tree_Sea.mals recognises that Pastoralist women play a vital role in dairy storage and consumption. With this mind, we aim to encourage Gender Equity in the following ways;
The most effective way the proposed project is predicted to be gender inclusive is through allocation of asset ownership to women within self help groups financed especially through dairy value chains.
The biggest challenge in pastoralist women is that they are not allowed to own neither land resources nor livestock. Because of this, they cannot attain collateral to apply for credit or have opportunities to participate within the meat-market trade and networks. In the case of milk/dairy products however, women usually have full control of these value chains.
The project breaks these barriers by intentionally favouring stock and sale of women assets within Cold Storage Facilities in-order to encourage commercialisation of their products within the local market. This will be done by permanently reserving 1 out of 3 cooling units to be solely rented out to women self-help groups.
Access to Quality Employment
Cold storage units being primarily rented by women will enable them to participate more actively in the livestock value-chain thus encouraging them to aggregate stock and sell dairy produce to terminal markets where they could acquire higher value from proceeds. Women will then establish individual businesses and diversify their income sources.
The cooling facility will also support both skilled and non-skilled workers within women committees during operation, sale and expansion phases of the project.
Do you qualify for and would you like to be considered for the AI for Humanity Prize?
Explain how you are qualified for this prize. How will your team use the AI for Humanity Prize to advance your solution?
The mini-grid component of the proposed technology is equipped with IoT features with GSM enabled smart meter points at a consumer level and sensor points at the generation level.
Operation monitoring is done to have daily, detailed feedback on energy generation, the equipment that consumes it and the subsequent impact of the application. Remote monitoring systems have enabled developers to record community electricity activities within any location through an internet enabled, graphical user interface.
On a larger scale, the installation of decentralised electrification systems that are monitored and managed across various East and Southern African borders has the potential to mine an array of data points in the most remote and largely inaccessible areas.
Data Science could be properly managed across various borders with the following customisation;
• Data Platforms to automate tracking of interconnected decentralised technology streams
• Impact engines that support an unlimited range of indicator models across various jurisdictions
