Sub-Saharan Africa’s lead-acid battery problems destroying industry’s green credentials

A damning report about battery recycling in Africa lays waste to the lead-acid industry’s claims that regulations are making it environmentally better and safer than lithium-ion.

The findings, from The Lead Recycling Africa Project, have found lead poisoning is severely under-reported in sub-Saharan Africa, where 800,000 tonnes (8% of annual world production) is made available each year for recycling.

General Electric gas turbine

General Electric is to provide three 25MW aeroderivative gas turbines to GEL Utility Limited (GEL) in Nigeria.

GEL is to install the trailer-mounted turbines at Nigerian’s National Petroleum Corporation’s (NNPC) state oil refinery at Port Harcourt to overcome chronic local grid outages and generate uninterruptible power. The engines are designed to provide baseload and backup power to support refinery operations.

The 49-year-old Port Harcourt facility is the country’s largest oil refinery and aims to regain full capacity for refining from its present 30% output. It has a total maximum capacity of 210,000 barrels per day.

“This project was not only important in getting the refinery back into full operation, but also to support Nigeria's long-term economic interests by achieving optimum refining capacity," said GEL chief executive Akinowole Omoboriowo.

The chronic power outages have forced Nigeria to import large amounts of refined petroleum to meet the electricity demand. The installation of General Electric’s turbines is to reduce the imports.

The units will start operations this month.

GEL signed a 20-year power purchase agreement with the Nigerian National Power Petroleum Corporation to modernise also two other refineries in the country.

Eaton's opening reception in Lagos

Power management company Eaton has opened an office in Nigeria’s capital Lagos.

“The development and use of innovative technologies is critical in increasing energy efficiency in Africa,” said Shane Kilfoil, managing director of Eaton’s Electrical Sector in Africa.

The company explained that the increasing demand of electricity due to Nigeria’s business growth has led to the decision to expand in Africa. “Africa’s energy challenges lie not in building more and larger power generation plants, but instead in investment in advanced power management technologies to enable businesses to do more with less energy in an increasingly resource constrained world,” Kilfoil added.

Nigeria’s federal government is currently restructuring the country’s electricity market. “The reform will enable Nigeria to overcome its huge deficit in the supply of electricity,” said Charles Iyo regional sales manager West Africa at Eaton.

The office in Lagos will also provide services to Western Africa. Eaton has several offices in Africa and 300,000 sq. ft. of manufacturing space on the continent for the production of its critical power supplies.

Schneider Electric Smart-UPS

Schneider Electric has introduced two models of its next-generation uninterruptible power supplies (UPS) to Southern Africa markets.

The UPS models, standard SMT and extended run SMX, are designed to handle low, medium as well as high load levels and to protect equipment against blackouts and spikes.

The models are equipped with features such as an intuitive LCD user interface, switched outlet groups, battery management indicator and an emergency power off option.

“The enhanced intelligent battery ensures that the temperature compensated charger extends battery life and advanced algorithms recommend replacement date,” said Schneider Electric distribution account manager Christelle Larkins.

A “green” mode enables efficiencies of more than 97% and saves utility and cooling costs without compromising performance or reliability, according to the UPS supplier.

“It is a trusted product to protect critical data and equipment from power problems as the UPS supplies clean and reliable network-grade power,” said Larkins and added that the models have already been introduced to European, US and Australian markets.

The UPS units come with a three-year warranty and can be used in the telecom sector, banks, retail stores, laboratories, medical sectors and areas with security devices.

Ballard and Amplats launch fuel cell-powered microgrid

Ballard and Amplat's off-grid solution

Ballard Power Systems and Anglo American Platinum (Amplats) are to test a fuel cell-powered microgrid prototype in a remote rural community in South Africa.

The companies will power 34 households in a 12-month trial with a generator system that is fueled by methanol and uses platinum group metals as catalysts. The fuel cell system is integrated into a prototype off-grid solution incorporating a battery bank and inverters that operate within the microgrid.

The system is designed to provide a total of 15kW of power and generate peak power of 70kW.

"This field trial will provide valuable insight into the market requirements of off-grid communities,” said Andrew Hinkly, executive head of marketing at Amplats. South Africa’s Department of Energy (DOE) has chosen the rural community of Naledi Trust as a suitable site for the trial as the area does not have any access to grid power and expanding the national network would be too expensive.

The next phase of the project will be the installment of 200 to 300 units in remote villages across the country, according to Godfrey Oliphant, South Africa’s Deputy Minister of Mineral Resources.

Ballard and Amplats are collaborating with power utility company Eskom and South Africa’s DOE to conduct the field test.

Power supplier EDF Energy and World Bank Group member International Finance Corporation (IFC) have agreed to cooperate in the development of off-grid electrification in sub-Saharan Africa.

A first pilot project will start in Benin and provide electricity for 25,000 people in its first phase, using hybrid solar-diesel networks and two biomass fired power plants. Other countries such as Mozambique, Tanzania and Myanmar will follow at a later stage.

"Almost 1.3 billion people live without access to electricity in the world. Bringing power to these people is a major challenge that we must address”, said Bertrand Heysch de la Borde, senior manager for infrastructure in Africa at IFC.

The goal of the cooperation is to supply power to half a million people living in rural areas. EDF and IFC will also seek for sources of financing to potential projects and explore sustainable co-investment opportunities where necessary, according to the companies.

"Electricity is a vital product without which no real development is possible. Access to energy for rural populations, who are more often the most disadvantaged ones, allows poverty reduction by developing income-generating activities, while also promoting education, health, access to water, etc,” said Edouard Dahome, EDF director for Africa and access to energy.

IFC is currently providing off-grid power through its “Lighting Africa” initiative to almost 7m people in several rural regions in Africa while EDF delivers electricity to 500,000 people on the continent.
