Full steam ahead for biogas engine fuelled by cow manure
A successful demonstration has been made of a GE Energy Jenbacher biogas engine powering a cattle manure-methane cogeneration plant at a large dairy complex in India’s northwestern state of Punjab.
GE’s 1 MW Jenbacher biogas cogeneration system has supported the model waste-to-energy conversion plant at the Haebowal dairy complex in the city of Ludhiana, where 150 000 head of cattle generate a daily total of 2500 tonnes of manure.
The project uses the biogas (a with high methane content) created during the anaerobic digestion of 235 tonnes of cow manure per day to generate electricity and thermal energy. Surplus energy from the engine is sold to the local grid of Punjab State Electricity Board (PSEB), while water heated by the engine is used to assist the digester fermentation process.
Nigerian tie up for Cummins
US genset manufacturer Cummins and Nigeria’s AG Leventis have created a joint venture called Cummins West Africa.
The new operation in Lagos will manufacture power generation systems with up to 1000 kVA output, supported by a network of service branches strategically located across the country. By utilizing exisiting manufacturing processes and training programmes, Cummins West Africa said that it would produce generator sets to the same quality levels.
At maturity, the Cummins West Africa facility in Lagos is expected to be one of the largest and most advanced genset manufacturing operations in Africa.
SA genset demand set to grow
Growth in the South African genset market is being driven by the main electricity utility company Eskom’s inability to ensure reliable and continuous power supply, according to a report by analysts Frost & Sullivan.
The report found that the South African market earned revenues of $73m in 2005, and estimates this to reach $130m in 2010.
It is expected that Eskom will run out of electricity supply capacity this year, and is already experiencing trouble with providing continuous supply, especially in the Western Cape region.
Companies in this region are suffering heavily due to production losses, and many of them are reverting to genset power, said the report.
