Carbon dioxide Footprint calculator for Manufacturing units

Posted by on Saturday, 12 February, 2011

Carbon foot print is the total amount of Carbon dioxide that is emitted, by a person, a family, an organisation etc.,

There are many carbon footprint calculators available in the internet.
some of the popular ones are :
http://www.carbonfootprint.com/calculator.aspx
http://www.nature.org/initiatives/climatechange/calculator/
http://www.carbonfootprint.com/calculator.aspx
http://www.epa.gov/climatechange/emissions/ind_calculator.html
http://www.safeclimate.net/calculator/

The general methodology of these calculators is simple. These sites ask you to esitmate on several factors like,

Food, travel,  utilities,  lifestyle etc.,  estimated   usage and the calculator does the job.

For example:

Food How often do you buy locally produced meat, vegetables and dairy products?
What about  organic meat, vegetables and dairy products?
Car Travel What kind of vehicle does one travel in?
Car, type of car, usage, fuel efficiency, bus, train, mileage, etc are esitmated and carbon foot print  calculated.
Air Travel Hours  personal air travel within one’s continent?
personal air travel to places outside the continent? Etc are asked and carbon footprint estimated.
Home utilities for heating / cooling etc What kind of house does one  live in? , How many people, How the  home is heated? cooled ? switiching off or on your lights/ fans/heaters/ ACs/ etc How warm/ cool  does one  keep the  home?

Others Electric gadgets, what all do you own, bought recently etc,
no of  pets, bills on pets etc., spend on jewellery, bath and grooming products, etc etc
are estimated  to arrive at your personal or households carbon foot print.

What about Manufacturing carbon foot prints ?

In UK  a site has launched a carbon foot print calculator for the manufacturers.

It is from a Government organisation.
It was launched in January  this year.

The url given by them is
http://www.mas-se.org.uk/resources_local/carbon-footprint-calculator-1.

But I dont find the site at the above url. Now.

Nevertheless, it is a good concept. Manufacturers should be able to assess their footprint and correct themselves  to minimize carbon foot print.

The concept is pretty interesting.

Imagine that for different manufacturing units like textiles, leather, watches etc., the parameters that the calculator will check will be different.  Obviously it will be Process specific.

If such a calculator is available, each unit will be able to measure their carbon foot print and take necessary action.  They can be asked to pay a carbon tax based on that.

Hope the site is rectified soon or someone else comes up with a carbon footprint calculator for the manufacturers.

China’s growing CCS activities

Posted by on Thursday, 10 February, 2011

China surpassed USA as the world’s largest emitter of greenhouse gases way back in 2007. China is trying to balance its growing energy demand and restraining its carbon emissions by substituting coal with renewable energy sources, increasing energy efficiency, and implementing carbon capture and storage. Numerous research and demonstration projects related to carbon capture and storage are underway in china. This issue focuses on the growing interest of china in CCS related activities.

Some of the areas where significant research and development is happening in china are

  • CO2 capture technology
  • CO2-Enhanced Oil Recovery (EOR)
  • CO2 storage
  • CO2 transportation

An overview of the china’s CCS activities is described below:

1.    Shidongkou power plant is an ultra critical, coal fired power plant with a capacity if 660 MW located in northern shanghai. The plant is additionally equipped with carbon dioxide capture technology that separates and purifies CO2 from a flue gas stream to produce 120,000 tonnes of CO2 per year. This is the largest such facility in china and one of the world’s largest carbon capture facility in the world. The captured CO2 is used food packing, dry ice and beverage carbonation.

2.    The PetroChina’s Jilin oilfield complex is the leading site for CO2-EOR research and development in China. Petrochina discovered vast deposits of natural gas in 2005 that contained over 20% CO2 concentrations. This CO2 is removed from the natural gas stream to inject into several oilfields in the complex. It is estimated that CO2 injection has enhanced oil recovery by 10-20%.

3.    China’s Huaneng group is the largest power generator in china from fossil fuels. They have teamed up with Calera group (known for its cement production process from CO2) to build a green campus. Accordingly, the flue gas generated in the fossil fueled power plant is captured and converted to calcium and magnesium carbonates.

4.    The Greengen project is an initiative of Huaneng group to set up a coal based thermal power plant with carbon capture plant to achieve zero emissions target. The group is also involved in international cooperation for CCS development. One of those projects is China-Australia cooperation framework of climate change and energy problems. this project aims at capturing 3000-5000 tons of CO2 per year from power plants based on carbon dioxide capture technology developed by Huaneng’s thermal power research institute.

5.    Shenhua group is working on R&D in carbon capture and storage at its coal-to-liquids plant which started its trial operation towards the end of 2008. The company is also working on storage measures including geological storage which will be put into operation in one or two years.

The speed of planning, development, construction and regulatory approval for CCS projects is really fast. The Shidongkou capture plant was designed and commissioned within a span of 1 year, just to give an idea. Considering the pace at which China is moving forward highlights the fact that it has immense domestic incentive to create and grow sustainably. If the results from the domestic and international demonstrations in CCS prove promising to the Chinese government, China could become a world leader in CCS technology.

A Study by PTRC on Carbon Leakage Claim

Posted by on Friday, 4 February, 2011

The Weyburn carbon storage project has reached a critical phase after the alleged carbon dioxide leakage from its storage site. A blog post on this issue can be accessed here. This leakage issue was considered as a setback to the various CCS demonstration projects in the world as many countries are betting a lot on CCS technology as a possible way out to the present climate change crisis. The Alberta government sent out a message clearly saying that safety of its citizens won’t be compromised while finding a solution to reduce greenhouse gas concentration in the atmosphere.

The leakage issue came to light after an independent consultant employed by a Saskatchewan farm couple to study the possible gas leakage from a storage site near their farm. The report of the consultant supported the claims of the farm couple that CO2 has leaked from the Weyburn storage site post its injection underground for enhanced oil recovery (EOR) operations. The Petroleum Technology Research Centre (PTRC) which is involved in monitoring Weyburn project site for any possible leaks was entrusted with the task of finding out the truth behind the claims of the farmer. Based on the extensive study done by PTRC, no results were found that could support the claim that CO2 injected into the reservoir migrated to the surface causing the leakage.

The finding of the preliminary study is encouraging but a detailed study has to be done to ascertain the facts provided by PTRC to make sure that CCS is a safe and proven technology.

CCS sessions at World Future Energy Summit 2011

Posted by on Wednesday, 2 February, 2011

The World Future Energy Summit 2011 was held in Abu Dhabi from 17th – 20th January. The summit brought together world leaders, policy makers, industrialists from across the globe to discuss and deliberate on the climate change challenges faced by the world and find practical solution to address these problems.  The four day session had 2 sessions exclusively focused on CCS.

The topic of the first session was “CCS: From pilot to implementation-sharing the knowledge”. This session was chaired by the CEO of carbon capture and storage association, United Kingdom. With CCS being increasingly adopted, the session explored the different ways of deploying CCS technology in a commercially viable manner and the lessons to be learned from the mistakes made in the pilot/demonstration phase. There was consensus among the panelists that technology was extensively available for capturing CO2 from natural gas fields and injecting it underground for enhanced oil recovery (EOR).  The cost for implementing this technology is high and for the business model to be viable, the CCS technology has to be clubbed with EOR to scale up to industrial scale. Walid Fayed of Booz & Company highlighted the potential to offset the CCS implementation costs completely if it is combined with EOR. The CO2-EOR strategy advisor of UAE said assuming a recovery rate of 7% from EOR operations, UAE oil reserves will increase by 6 billion barrels and the whole of Middle East region by 46 billion barrels.

The second session was on “Kick starting a CCS future – Overcoming the regulatory and financial barriers”. The focus of this session was on identifying various barriers to the implementation of CCS and the efforts to be taken by financiers, policy makers, and industrialists in bridging this gap. Some of the barriers identified by the panelists are: Safety of storing it underground as CCS is still unproven, risky and expensive, Whether the technology can be scaled up and used on power plants, fear of decrease in investment in renewable energy sectors, financial incentives are mostly transitional, legal and regulatory frameworks are absent in most of the countries and public awareness & acceptance is limited. The panelists considered CCS as a “game changer” given its potential to generate additional revenues under CDM along with EOR.
