African development starts on a local level, and there is a crucial need for funding in local communities to insure a better future. We support local communities with investments in education for youth, and technical & workforce training for adults. Training, development programs, and ongoing support mean that people are given every opportunity to reach their potential. Better social development is essential for the future.


Over the course of our partnerships, we expect the creation of hundreds of jobs along with a wide variety of petroleum infrastructure projects to take place. Significant investments will need to be made throughout Africa. The partnership will continually hire African citizens and work with African owned companies. Outside contractors will only be used if necessary. We aim to put our own people and businesses first, whenever possible.


Intank's vision is to support and grow a modern, diversified, efficient, and financially sustainable “Energy Economy” that will ensure that all African homes and industries have access to an adequate, reliable, affordable and environmentally-sustainable supply of energy. Our role is to lead the effort to meet their needs and to support the accelerated growth and development agenda that has been envisioned for the continent.
