Should companies use carbon offsets in response to the deepening climate crisis?

It’s increasingly accepted that action must be taken in order to address .

CO2 emissions are a big part of the problem and laws, social pressure and good conscience are encouraging companies to reduce their levels of pollution.

The problem is, in some industries, creating CO2 is inevitable: it is simply part of the process. So, what can these businesses do about their emissions to meet targets and contribute less to climate change?

Carbon offsetting is one method people opt for.

What are carbon offsets?

In a nutshell: carbon offsets allow companies to pay for low-carbon practices elsewhere, theoretically ‘balancing the scales’ against the carbon they’ve emitted themselves. This is done on a credit system.

When one company has reduced carbon dioxide (e.g. by planting trees) or avoided carbon emissions (e.g. by building a wind farm in place of a coal power plant) they are awarded ‘carbon credits’.

These can then be sold on and essentially cashed in against the carbon emissions of the buyer. The theory is that the buyer’s emissions have been canceled out or ‘offset’ by the seller’s reductions.

Is carbon offsetting a good thing?

The attitudes towards carbon offsetting are mixed. On one hand, it’s good that there is at least something being done to consciously address carbon emissions but on the other hand, it seems like avoiding the real problem.

Surely it would be better to prevent or reduce carbon emissions in the first place, rather than carry on as normal and then attempt to buy a clear conscience?

This is especially true if you can improve productivity and save money at the same time!

How to reduce CO2 emissions in gas turbines

Older tend to be less efficient and pollute more. One option is to invest in a new turbine, but that is not always financially possible.

However, whether you’ve got new equipment or an older version, there are still ways to reduce CO2 emissions. 

Over time, inevitably become fouled. This fouling interrupts airflow, leading to incomplete combustion, and more fuel is subsequently required to support the inefficient system.

All of this means higher than necessary carbon emissions.

At Rochem, we specialize in cleaning equipment and chemicals for gas turbine compressors.

Below is an example of how using our products not only drastically reduces carbon emissions but also saves fuel and increases productivity.

Rochem case study: reducing carbon emissions

The following is based on a General Electric frame 5 gas turbine operating on an offshore installation.

The gas turbine is installed with . An online compressor wash was performed using Rochem cleaning chemical.

Post online wash data indicates a fuel saving of 65 m³/hr with a load increase of 300 kW.

Based on annual operating hours of 658 hours the potential CO2 saving is 1394 tonnes per year with the reduced fuel consumption as a result of regular compressor washing.

Conclusion

So, should companies use carbon offsets to address the climate crisis? It’s an option but we believe it’s far better to prevent avoidable CO2 emissions in the first place rather than attempt to later simply ‘balance the scales’.

In the gas turbine industry, it’s clear that regular compressor washing is an effective way to not only reduce CO2 emissions but save significant fuel at the same time.

Plus, when doing this is better for business as well, there’s really no question about which option is best.
