Green electricity to beat high tariffs

Karachi —The concept of bio waste energy generation is a cost effective way to generate electricity being used by Karachi Electric Supply Company at a commercial scale which is supposed to reduce generation cost enabling the utility to pass on the benefits to hard hit power consumers besides setting an example for rest of the country to follow suit.

The initiative is appreciable on the part of KESC yet to NGOs and pressure groups never tired to raise a hue and cry over energy shortage should also comeforward to conceive such projects of renewable energy generation to make easy the life of the fellow citizens in the real life as making headlines denotes gaining for cheap publicity unless something is done to redress the sufferings of the common man.

According to a report, Karachi Electric Supply Company, as part of its fuel diversification, green electricity generation and sustainable development vision, is planning the development of one of the world’s largest Bio Waste to Energy Project of its kind near the Landhi cattle colony situated inKarachi. This plant is likely to have the potential of generating up to 22 MW of electricity fueled from biogas alone.

A localized Biogas plant is a socio-economically sustainable venture and reliable in comparison to wind or solar, which are vulnerable to extraneous variables, biggest being weather conditions. The Landhi Biogas project in Karachi will not only generate up to 22MW of green power but will also be producing up to 300 tons/day (tpd) of organic fertilizer as a meaningful byproduct. This organic fertiliser has special application in place of eroded soil which has lost it’s utility and where standard urea fertilizer won’t be effective. In addition to the above, this eco-friendly energy unit will also earn a significant amount of carbon credits, thereby making this Project economically viable.

Under this sustainable, renewable energy project, up to 4,200 tons of bio-degradable waste will be collected on a daily basis largely from cattle farms in Landhi (feedstock) and organic food waste from industries, food outlets and wholesale markets (co substrates) throughout Karachi. Under the signed memorandum with Karachi Dairy Farmers Association in December last year, the Association would provide 3,500 to 4,000 tons of cattle waste on a daily basis to KESC to be used as feedstock to produce biogas required for electricity generation. This landmark step will facilitate waste collection studies, project implementation and rollout of many socio-economic initiatives in the Landhi area of Karachi.

KESC has also signed an agreement with biogas technology providers M/s Highmark Renewables (HRR Canada) for onsite technical studies (Phase I) leading to project plant design, which now stand completed. During May to July 2011, HRR conducted on-site feasibility analysis using HRR’s patented technology to produce biogas. The initial trial runs have demonstrated that the customized ‘recipe’ and feed plan are feasible, yielding significant amounts of biogas during the trial run. Currently, KESC is moving into the Phase II of the project. This phase entails activities which include land development, and developing, waste collection mechanisms, Gold standard carbon credits, formation of strategic partnerships and financial close.

Furthermore, KESC is looking for ways to engage private and public sector entities for provision of benefits to the residents and workers of the Landhi Cattle Colony. At the moment a ‘social needs assessment’ is in progress and going forward, the project team is looking towards evolving a mechanism to ensure that the benefits can be provided to the society in a sustainable fashion. KESC is looking forward to working with the local / city government and leading national and international NGOs, for developing a mechanism to successfully roll out this and other similar CSR initiatives.

Meanwhile the cap on generation capacity of provincial power plant had been removed under the new national power policy and provinces were now free to set up plants of any capacity to meet their needs. This power devolution infact need to invite private sector to play its due role in combat the most nasty issue of power shortage which had adversely affected socio-economic development across the country resulting in flight of capital to the neighboring countries specially Bangladesh, Sri Lanka, African region and other countries. This potentially dangerous trend could only be stopped through improving the energy as well as law and order situation as both issues scaring away the existing investors but quite sufficient to drive away foreign investment as well. According to provincial minister for power Shazia Marri, the government was considering the production of biogas from sugar mills distilleries. Marri pointed out that Chinese companies were preparing a paper for power generation through low-head hydel projects at main canals in Sindh as had been done in Germany and other European countries. The minister for power has also emphasised the need for exploring clean, inexpensive, and environment-friendly, and renewable options for electricity generation including the wind and solar resources so that power generation needs of people could be met in the shortest possible time and best possible manner. She said the Sindh had been actively making progress towards exploiting the abundantly available renewable wind power resource in the province and under this initiative; the province would be able to generate 500-MW electricity through wind energy by March 2013.

In order to encourage investment in power sector the government has offered 20 per cent return on coal projects. In this respect at least one coal-fired power plant would be commissioned by 2015-16 while 19 companies have submitted a bank guarantee of $300,000 with the government for setting up renewable energy project in Sindh.

Energy experts believe that seaweed holds enormous potential as a biofuel

WASHINGTON: Energy experts believe that seaweed holds enormous potential as a biofuel alternative to coal and oil, and US-based scientists said Thursday they have unlocked the secret of turning its sugar into energy.
A newly engineered microbe can do the work by metabolizing all of the major sugars in brown seaweed, potentially making it a cost-competitive alternative to petroleum fuel, said the report in the US journal Science.
The team at the Berkeley, California-based Bio Architecture Lab engineered a form of E. coli bacteria that can digest the seaweed’s sugars into ethanol, it said.
Unlike other microbes before, researchers found it can attack the primary sugar constituent in seaweed, known as alginate.
“Our scientists have engineered an enzyme to degrade and a pathway to metabolize the alginate, allowing us to utilize all the major sugars in seaweed, said Daniel Trunfio, chief executive officer at Bio Architecture Lab.
The advance “makes the biomass an economical feedstock for the production of renewable fuels and chemicals,” he said.
A company spokesman told AFP that the lab currently has four aquafarming sites in Chile where it hopes to “scale up its microbe technology as the next step on the path to commercialization” in the next three years.
Seaweed is seen as an appealing option for biofuel because, unlike corn and sugar cane, it does not use arable land and so does not compete with crops grown for food.
Less than three percent of the world’s coastal waters can produce enough seaweed to replace some 60 billion gallons of fossil fuel, according to background information in the article.
At peak production, seaweed could produce 19,000 liters per hectare annually, about twice the level of ethanol productivity from sugarcane and five times higher than the ethanol productivity from corn.
Funding for the research came from the US Department of Energy’s Advanced Research Projects Agency, a grant from InnovaChile, and Norwegian oil giant Statoil

Chesterfield BioGas Appoints MD

Chesterfield BioGas Appoints MD

UK - Biogas upgrading and refuelling equipment manufacturers Chesterfield BioGas Ltd (CBG) has appointed Stephen McCulloch as Managing Director.
He joined the organisation as Sales Manager in 2008 when it was first formed as a division of Chesterfield Special Cylinders Limited (CSC). Prior to that Stephen had been in production and sales management positions at Doncasters Group Ltd.
When CBG became a separate operating company within the Pressure Technologies group in Autumn 2010, Stephen became Director of Business Development. It was around this time that a biogas upgrading plant supplied by CBG was at the heart of the system which made the first injection of gas produced from waste into the UK national gas grid.
Based in Sheffield, CBG provide solutions for the cleaning, storage and dispensing of biomethane, produced from wastewater treatment and anaerobic digestion of organic waste. The company also manufactures and installs permanent and temporary fuelling stations for vehicles operating on compressed natural gas.
Now, as MD, Stephen will drive the company’s growth derived from an increasing flow of projects in the UK. Staff numbers are progressively increasing as CBG has rapidly established itself as a market leader in this sector of renewable energy in the UK.
He has also recently assumed the Chairmanship of the Biomethane-to-grid Working Group at the Anaerobic Digestion & Biogas Association (ADBA) - a leading trade body in the renewable energy from waste sector.

New success for city green energy business

Chesterfield BioGas Ltd (CBG) has today secured a contract to supply and install upgrading equipment for the UK’s latest project to use gas from renewable waste resources and inject it directly into the national gas grid.
The contract win is seen as a good deal for the company, a subsidiary of Pressure Technologies plc (PT).
The system in Stockport, like the first successful UK venture of its kind in Didcot which opened in October 2010, will feature, at its heart, an upgrading unit designed and manufactured by CBG’s partner, Greenlane® Biogas of New Zealand.
The modular ‘Kanuka’ unit will take the raw biogas produced by anaerobic digestion of food waste from local hotels and restaurants and, using the proven water-wash process, upgrade it to 98% pure biomethane. The unit is capable of processing up to 300 cubic metres of gas per hour and features a newly patented water-flooded screw compressor.
The facility, which will open in Autumn 2012, will be operated by Fairfield Bio Energy - a partnership between green energy firm Bio Group Ltd and Centrica, the owners of British Gas. It will generate enough renewable gas to supply the natural gas requirements for 1,400 homes.
CBG’s contract, including ancillaries and remote monitoring services, is worth approximately £1m.
CBG’s Managing Director, Stephen McCulloch, said of the contract win, “This is a considerable vote of confidence in our technology and performance. Our unit uses the proven Greenlane® water-wash process which is successfully operating at over 60 sites around the world.”
“CBG established a firm working relationship with Centrica in the course of our work at the first UK project, which opened in Autumn 2010, and we are delighted to be their preferred supplier once again.”
Describing the success of the first system in Stockport, he added, “Our first project at the Thames Water site at Didcot used raw biogas captured during the treatment of waste water. The fact that the new Stockport site will use gas derived from a completely different waste material is a significant testament to our upgrading system and its versatility in coping with variable inputs from the anaerobic digestion process.”
Group Chief Executive, John Hayward, was just as enthusiastic and said in a company statement, “Chesterfield BioGas is firmly established as the market leader in upgrade technology in the UK. As the only UK-based supplier and installer of this type of technology, we have the experience and expertise to manage projects to the exacting engineering and health and safety standards demanded by large utility companies and gas grid operators. We look forward to further progress in this market over coming months.”
