African startups: striving for a world with cleaner energy

African countries are some of the world’s top places to apply technologies related to renewable energy. Hence, the December 2015 announcement that WeChat would invest about $3.4 million USD in African startups didn’t come as a surprise. Here are a few examples of some of the initiatives that may hold the key to the future of clean energy:

Smart Solar Kiosk

Based in Rwanda, this team claims to have developed a mobile solar Kiosk, aimed at charging small electronic devices, product sales and Wi-Fi internet access for on-the-move customers.

Henri Nyakarundi leads the project, which has implemented 20 kiosks in Rwanda thanks to a partnership with Airtel Rwanda. You can watch a video demo of these kiosks at their official website, http://www.a-r-e-d.com/

ColdHubs

This Nigerian startup thought of a solution to store and preserve vegetables and fresh fruit: modular, solar-powered walk-in cold rooms that are installed in farms and markets that are close to retailers and farmers. The temperature in said rooms (5°C) prolongs the freshness of vegetables and fruits up to 21 days instead of 2 days with no refrigeration. Their business model includes a pay-as-you-store option that allows farmers to pay a flat fee every day for each crate that they store.

Strauss Energy

With the promise of providing disruptive energy solutions, this company’s goal is to diminish the energy deficiency in the African continent. Led by Tony Nyagah, they introduced a new technology to the Kenyan market: solar cells on roof tiles, which are capable of powering a house while saving roofing costs at the same time.  

They plan to feed the excess power from commercial or residential units into the country’s  grid in order to provide home owners with additional income. A return on investment is estimated to be reached in 18 to 24 months.
