Compressed air – the cheapest carbon reduction you will ever find

A price has already been put on carbon: it comes in the form of the energy tax placed on every kilowatt-hour you buy; the carbon tax that is included in the price of that kilowatt-hour; it comes in the form of fulfilling legal requirements such as the new European energy efficiency directive; and it is present when you have to disclose your company’s CO2 emissions to clients and investors.

One way or another your factory is, just like our planet, already being affected by carbon.

After conducting several thousands of customer projects in factories around the world Enersize is seeing that the easiest and cheapest way for you to reduce carbon emissions is to optimize your compressed air system. Compressed air is most likely running a large part of your manufacturing processes and is generally the most expensive source of energy use. The reason for this is that compressed air is a very inefficient process.

It’s hard to believe, but it is true: the average compressed air system emits 30-50% more CO2 than necessary. This also means a 30-50% higher electricity bill than necessary, for a process that often uses a large share of a plant’s electricity.

To exemplify: A smaller factory had 122 leaks. Fixing them saved that customer 110 000 EUR. And the pay-back time was 32 days!

And, in what may be an unofficial record for the company, one large Swedish manufacturer the team at Enersize visited had 3600 leaks in their compressed air system that were all easy to fix…

This is why LMS-Nordic was selected ‘Supplier of the year’ award from industrial maintenance and supply company Momentum Industrial in 2018 (see image of Daniel Winkler accepting the award below), for providing the service that documented the most tonnes of CO2 reductions. Together with Momentum, LMS-Nordic managed to save over 4.5 MSEK and over 2000 tons of CO2 through leakage management projects.

The fact of the matter is that most, if not all, users of compressed air are burning CO2 for no reason other than lack of correct information from their systems.

The following are some averages financial waste and unnecessary CO2 emissions for a well-maintained plant with only 30% leakages and inefficiencies (kWh prices and CO2 emissions), which you can relate your own plant to:

250kW Compressor capacity – 230-ton CO2 and 65.000 EUR annually

1000kW Compressor capacity – 920-ton CO2 and 260.000 EUR annually

5000kW Compressor capacity – 4.600-ton CO2 and 1.300.000 EUR annually

These carbon savings are not only the cheapest you can obtain on the market, they are usually achieved very quickly. In addition, reducing the carbon intensity of your compressed air system will not only reduce your company´s environmental impact, it will make a significant contribution to your bottom line within the first year of implementation. In many cases even within the first month!

We would argue that compressed air savings are by far the cheapest, fastest and easiest means of reducing carbon emissions. The key is doing it the right way and with the right tools.

If considerable CO2 reductions and ROI within a year are insufficient reasons to act, then perhaps the following reasons are more compelling:

  1. Having an optimally managed compressed air system reduces the risk of downtime and quality disturbances due to unstable compressed air delivery;
  2. Efficient compressed air systems provide you, your employees and customers a great deal of satisfaction as well as tangible results that go into your annual reports and ISO requirements of continuous improvements; and
  3. You can reduce your overall investment and operating costs significantly during the life span of the compressed air system. In fact, our software and service often eliminate or delay further investment requirements.

So, next time someone tells you how much it costs to reduce your carbon emissions, make sure you tell them not all carbon reductions are created equal. Some are worth more and some are worth less.
