Three Nigerian innovators have been shortlisted for the Africa Prize for engineering solutions to address the continent’s challenges.

This was revealed in a statement by the Royal Academy of Engineering.

The three Nigerians are part of a group of 16 African innovators, spanning 10 countries, who will compete for the £25,000 Africa Prize for Engineering Innovation.

The countries the shortlisted candidates are from include Angola, Cameroon, Ethiopia, Ghana, Nigeria, Sierra Leone, South Africa, Tanzania, Uganda and Zimbabwe.

According to the organisers, shortlisted innovations provide engineering solutions crucial to UN Sustainable Development Goals – including water, healthcare, agriculture, education, food security, waste, and energy challenges.

The innovations include a treatment to convert acid mine drainage into drinking water; a portable aquaponics unit that uses fish waste to boost production of vegetables; a robotics learning tool for children; a remote healthcare monitoring system, and an eco-friendly cooking stove which absorbs black carbon.

Four finalists will be chosen by mid-2023 to pitch their innovations and business plans to Africa Prize judges at an event in Accra, Ghana.

The winner will receive £25,000, and three runners up will win £10,000 each; an additional One-to-Watch award of £5,000 will be given to the most promising innovator.

The Africa Prize

Launched in 2014, the Africa Prize is awarded annually by the Royal Academy of Engineering to ambitious African innovators creating local and scalable solutions to pan-African and international challenges.

It is supported by the UK’s Department for Business, Energy and Industrial Strategy and The Shell Centenary Scholarship Fund.

The Africa Prize shortlist will benefit from a unique package of support including business incubation, mentoring, fundraising and communications.

It also includes access to the Academy’s global network of high-profile experienced engineers and business experts in the UK and Africa.


This year’s shortlisted innovators join the Academy’s 134-strong Africa Prize alumni network, which includes innovators who have achieved significant commercial success and social impact across the continent following their participation in the Prize, such as 2022 winner Norah Magero and her portable solar-powered fridge solution for transporting medicines.

Africa Prize alumni are projected to have an impact on more than three million people in the next five years, and have already created 3,585 jobs – 1,766 for women and 211 for persons with disabilities – and raised more the $14 million in grants and equity funding, directly contributing to 12 of the UN Sustainable Development Goals.
