Early

Round 10

Women and children are disproportionately impacted by energy poverty and can spend up to ten hours a week collecting fuel for energy use. Walking great distances for fuel too often puts women in vulnerable situations and cooking with these fuels endangers their health. This causes many young girls to leave school to collect fuel and prevents women from participating in other income-generating activities.

Africa Power develops, deploys and sells off-grid solar solutions for Africa and has developed a range of Productive-Use-of-Energy (PUE) products. Partnering with Solar Sister’s, this project uses Solar Sister’s last-mile distribution networks in Tanzania to trial Africa Power’s solar solution and drive access to appliances. The project takes a gender-inclusive approach as it promotes climate resilience and food security.

Early

Round 10

Food shortages and malnutrition impact many sub-Saharan African countries. In Uganda, milk consumption alone is at 65 litres per year, falling well below the recommended consumption of 210 litres that the World Health Organisation recommends for a population of that size.
While Uganda has twice the milk processing capacity compared to its current milk collection volume, unlit roads and lack of refrigeration means that the night milking from smallholder farms – representing 90% of all farms – cannot be sold in the formal milk chain causing vast waste and shortages.

Africa Power looks to design and test a range of solar-powered, high-efficiency fridges. These off-grid fridges can help small farmers earn more money from their dairy products and reduce milk waste by storing it for longer. This project hopes to show that increasing nutrition and reaching Net Zero-carbon products are not mutually exclusive.

Pakistan

Smart green grids including mini and main grid technologies

Early

Round 10

More than 50% of people in Pakistan’s rural areas live without electricity. It increases their reliance on energy imports and fossil fuels.
SAFER seeks to improve access to sustainable energy in rural Pakistan by harnessing agro-waste from fibre production and turn it into a sustainable and accessible energy source.

It forges two technologies to create a circular model based on food, fibre, and energy while rendering zero waste. One technology produces high-quality textile fibres using agro-waste such as banana peels. The fibre production process generates a second round of agro-waste, maximising resource use. Through a second technology, the power of agro-waste to generate syngas can be harnessed and used to produce electricity.
By converting agro-waste into renewable fuel, SAFER can alleviate the burden on Pakistan’s overstretched energy sector.
Beyond energy production, SAFER can also help improve Pakistan’s textile sector, the country’s largest exporter and facilitate effective waste management.

Round 10

Connecting conventional grids to rural and urban areas encounters challenges such as limited coverage, high costs, and unreliable supply. Solar energy can help fill the gap, but deterrents like intermittent supply and high costs exist.
The Decentralised Energy Market Access And Co-finance (DEMA2C) consortium will develop a technology that can supply on-demand green energy to off-grid communities. The technology hopes to achieve this by optimising the link between generation and consumption. It doesn’t require extra panels or expensive storage banks. It also doesn’t rely on fossil-fueled generators.

DEMA2C also seeks to provide an energy-as-a-service model. This model is backed by a unique payment platform that allows investors to track their return on investment in real-time. It is hoped that this will stimulate investment into distributed energy sources and attract investors who have been shying away from microgrids.

Round 10

OMASI, the local NGO partner of Science Technology and Innovation for Development (STI4D), initiated off-grid dairy businesses across the region. Women who sold their milk to the dairy were suddenly empowered. They could sell their milk, buy family essentials in nearby shops, and invest some of the funds in school fees for their children.

These dairies depend on reliable power since so much capital is tied up in products which will quickly spoil if refrigeration fails. A 63 kW diesel generator therefore powered each dairy. Grid supply in Northern Tanzania, however, is unreliable. Clean energy from mini-grids, on the other hand, is a more reliable power source. As traditional mini-grids struggle with the high and variable dairy loaad, STI4D and OMASI aim to develop cost-effective technology for clean and reliable power, ensuring sustained dairy operations. The same technology approach could also support other high-power productive use anchor loads in communities.

Sustainable cooling

Early

Round 10

In Uganda, it was estimated that around 2.5 million people would not have enough food in 2023, with this figure likely increasing year on year. Roughly 10% of rural populations have access to electricity, which makes it hard to use efficient irrigation systems and storage in agriculture. This leads to post-harvest losses and exacerbates food insecurity.

However, improved cooling systems can tackle these problems and enable better food security. AD produces biomethane, a low-cost and low-carbon fuel that works well for rural, off-grid communities. With biomethane, we can power cold storage units, providing a reliable means of preserving perishable goods. Notably, biomethane production is versatile as various organic materials, such as animal manure and market waste, can be used.

Uganda is one of the few countries using AD technology to provide household cooking and electrification in sub-Saharan Africa, though insufficient feedstock supply and operating maintenance limit adoption and long-term application efforts.
The BioCool project aims to introduce a new Energy as a Service (EaaS) model to tackle this issue by guaranteeing access to reliable, affordable, low-carbon fuel. This model shifts responsibilities to energy providers and ensures customers only pay for the fuel they consume.
