Great strides have been made in Africa’s development in biomass. Interestingly, Africa has the highest portion of bioenergy, at 45% of the total energy mix, thereby validating the continent’s potential to capitalise on this renewable energy source. Currently, industrial scale biomass and waste-to-energy plants being explored in Angola, Tanzania, Cote D’Ivoire, Kenya, Malawi, Mauritius, Nigeria and Ethiopia.
Within a global context, using GE’s renewable steam technology, the Kamisu Biomass Power Generation plant in Japan will run on 100 percent biomass to generate 50 megawatts (MW) of reliable energy. According to GE, this is one example of how the company is adapting its technologies to meet market demand to support more renewable fuel sources like biomass.
Lee Dawes, GE Steam Power Sub-Saharan Africa CEO, states that the South African context will be different. While biomass and waste to energy are being significantly considered, there has been no clear determination on how it will be implemented. “A consideration to reduce CO2 emission could be a coal to biomass conversion. Depending on the size of a plant, existing power plants can be adapted to utilise a wide range of biomass fuels to supplement or displace coal to reduce CO2, NOx and Sox”.
In accordance with the Paris Agreement, and mounting concerns for the adverse effects of climate change, South African policies are striving to accelerate decarbonisation; to meet demands for reliable, affordable and environmentally sustainable power. While biomass is considered a renewable energy source, its sustainability will depend on continuous growth and the cultivation of the biomass sources to ensure a carbon neutral state. Where the biomass is a secondary revenue stream, it often contributes to the commercial viability of such projects”.
With all these developments in energy, it’s imperative to note that, despite the energy source employed, maintaining a sustainable balance between developmental and national environmental needs is crucial. Managing current challenges to ensure energy security and economic stability remains high on government’s agenda. Policy makers will have to devise and implement strategies to ensure a successful transition, taking into consideration the various implications of such a shift; such as the interdependencies of fuel sources along with impact of renewable penetration on the grid.
Once countries have chosen the fuel that best meets their energy, cost and sustainability needs, GE supports them with the most efficient technology with the least possible environmental impact. In countries like South Africa where coal provides self-sufficient and affordable means of energy security, it is essential that the plants provide high levels of efficiency and rely on leading air quality control technologies. Therefore, access to finance, upgrade, maintain and in some cases extend the life of existing assets in a sustainable manner is essential.
GE has made significant progress in assisting governments and utilities to improve the availability and reliability of their plants with the leverage of private finance. This has been implemented by capitalising on the opportunities presented by new digital solutions. “Across the world digital technologies are transforming the energy industry by increasing levels of productivity, lowering operational costs and extending the life of machinery. It’s time for South Africa to join this Fourth Industrial Revolution.” The rolling power blackouts, which carry a significant economic burden
It is critical to also note that responsible investment in energy goes beyond infrastructure and technology, it similarly concerns people and policy decisions. GE intends on investing in the right technologies, developing the necessary technical skills needed to help the industries grow, and support the development of local suppliers. In partnership with Eskom, GE has invested considerably in skills training;inclusive of artisans, welders, engineers, fitters and boilermakers. In addition, they support local businesses through a preferential procurement process.
GE understands the importance of ensuring that the future generation of engineers, technicians and scientists have access to the training and support that they need to develop and contribute to the development of the country. Technology and skills development are key drivers to ensure long-term development of any sector, economy or country. As two of the continent’s most revered sources within the energy realm, GE and the Africa Energy Indaba have been placed as thought leaders in this revolutionary industry. Anyone vested in the sector will do well to attend this year’s prestigious Africa Energy Indaba exhibition to stay updated on topics affecting energy stakeholders and its entire value chain.
