Remeha hydrogen admixture boilers first to be Kiwa certified

APELDOORN – As the first Dutch certification body, Kiwa has certified various Remeha boilers for the use of natural gas blended with up to 20% hydrogen. The energy transition in the Netherlands is in full swing and one of the ways to reduce CO₂ emissions is by adding hydrogen to natural gas, a process also known as admixture.

Adding hydrogen to natural gas is relatively easy. The network operator adds hydrogen to the natural gas network, using the existing infrastructure and certified boilers. Various Remeha boilers currently have a Kiwa certification for using natural gas blended with hydrogen up to 20%. As far as Remeha and Kiwa are concerned, the Netherlands can start using hydrogen admixture boilers tomorrow.

Significant CO₂ reduction

‘Blending hydrogen into the natural gas network is the most pragmatic way to quickly make a big step in the CO₂ reduction goals we are pursuing,’ says Marco Bijkerk, manager innovative technologies at Remeha. ‘With these new central heating boilers, Remeha clearly demonstrates we can and will contribute to CO₂ reduction as of now. Blending natural gas and hydrogen is a proven way to reduce CO₂ emissions. ‘Mixing natural gas with 20% hydrogen gas leads to a significant CO₂ reduction of 8%.’

Hydrogen pioneer

Kiwa already demonstrated last year that network operators can relatively easy adapt the gas network for the distribution of natural gas blended with hydrogen. The development of hydrogen-suitable systems for central heating and hot water supply is a logical consequence. However, a lot of sustainably generated energy is needed to fully switch to hydrogen. Currently, 20% admixture is a realistic measure, since the amount of available hydrogen is still very limited. ‘Kiwa plays a pioneering role in new applications of hydrogen,’ says Falco Thuis, business unit manager at Kiwa. ‘Kiwa and Remeha have a long-term partnership in the field of new technologies such as the application of hydrogen.’

The next step

In the Rozenburg district of Rotterdam, Remeha and Kiwa are already testing a 100% hydrogen boiler. The entire chain is being examined: generation of green electricity, electrolysis and transport via existing pipes to the Remeha Hydra, a 100% hydrogen central heating boiler. The tests with fully hydrogen powered boiler systems will be further expanded in 2020 to other districts throughout the Netherlands. Remeha foresees an important role for hydrogen in the Dutch energy transition because of:

  • No CO₂ emissions;
  • Use of existing gas infrastructure;
  • Large-scale storage of sustainable energy
