New Dutch Gas is on the way!               - Technical background -

Content of notification:

From 1 January 2022 the composition of the natural gas permitted to be distributed and used in the Netherlands will gradually be changed. This will mean that gas appliances approved for importation into the Netherlands must be suitable for the new composition. Appliances as currently supplied within the Netherlands will not be able to safely use all the gas compositions which may be supplied after 1 January 2022. The requirements set down for gas composition following 1 January 2022 are set out in the Appendix (Group K). In the longer term (post 2030) it is possible that the composition of the gas may change once again. The requirements relating to that further potential new composition are also set out in the Appendix (Group E).

Regulations:

The Ministry of Public Health, Welfare and Sport will shortly be bringing out a decision on the date following which the sale of appliances in category "I2L" will no longer be permissible. The requirement for the Netherlands will then be that natural gas appliances must be category "I2EK". It is not yet completely clear when the Ministry of Health, Welfare and Sport will make their announcement, or what period will be allowed for the transition. Current expectations are of a period of some 3 to 5 years. As soon as we have further information we will of course publicise this. In the meantime you should keep an eye on our website for developments.

Background:

The so-called "L gas" used in Dutch households is of a composition unique in Europe. Natural gas used in other parts of Europe has a higher calorific value, so that the Netherlands forms a kind of "gas island". Change is already underway however, with further change in prospect. Two thirds of the natural gas in the Groningen field has already been consumed, while the production of high calorific value gas from the smaller Dutch fields is also falling off. In order to make up for this, natural gas is already being imported from Russia and Norway, leading to changes in the composition of the natural gas supplied to households. The gas will in particular contain more of the higher hydrocarbons. The main constituent of our natural gas is now methane, but in future the methane content will fall and the gas will contain more propane and butane. The consequence is that existing gas appliances will require replacement or modification. It is anticipated that the replacement of appliances will come into effect after 2021.

Details I2L -> I2EK:

Netherlands Technical Agreement NTA 8837:2012 was published at the end of 2012, and sets out the details relating to gas group K of the second gas family: gas composition, gas pressures and conditions for 1) normal use of the gas appliances and 2) testing of gas appliances.

The NTA may be purchased via www.nen.nl.

As well as the requirement that appliances must be suitable for "K" gas, they must also be capable of adjustment to allow the use of "E" gas. Where up to now appliances have required approval and certification for the "L" reference and limit gases, manufacturers must now develop their appliances and have them inspected using the reference and limit gases for the new gas group K and the existing gas group E. The majority of manufacturers were already certifying their products for gas group E, so it is probable that no action will be required in this regard. Action will however probably be required in respect of gas group K.

Since KIWA have been involved from the outset in the drafting of NTA 8837, we are also well prepared for this new step towards the future. With a fully equipped laboratory and our wealth of in-house expertise we are ideally placed to assist you with all your design and approval queries.

 We also aim to keep you closely informed of new developments as these arise. Stay up to date on www.1kiwa.com/eup
