The Eusebius Church in Arnhem and its special heating system

Heating of a monumental church by using green hydrogen


Heating a monumental church building with sustainably produced hydrogen: the parties HyMatters, HAN University of Applied Sciences, DEKRA, the Eusebius Foundation Arnhem and the municipality of Arnhem have joined forces in this ambitious objective. Never before has hydrogen from a sustainable source been used for heating a monumental church. However, this offers an opportunity to reduce natural gas consumption in monuments.

Heating large monumental buildings such as the Eusebius Church requires an enormous amount of energy and can only be insulated to a limited extent. The Eusebius Church solves this issue by meeting part of the heat demand with floor heating sourced from a local heat network. However, underfloor heating provides only slow convection heat, and this is not sufficient to make the building comfortable in a fast and efficient way, for example during events. Up to now, this has been solved by using natural gas-fired radiant panels for additional peak heating. This innovative project focuses on radiation panels and the associated infrastructure required to use hydrogen from local sustainable sources for peak heating.

The Eusebius Foundation has been bold enough to take on the challenge of being the most sustainable church in the world. The first phase of this project will investigate feasibility of meeting part of the heating demand via green hydrogen. The project team has expertise in the fields of energy grids, hydrogen technology, safety and monumental buildings. The project provides a design for the hydrogen installation with the associated infrastructure and an implementation plan. The results are expected in the spring of 2020.
