An appraisal report on the engineering challenges of developing
domestic hydrogen appliances, written by Frazer-Nash in conjunction
with Almaas Technologies, has been published by the Department for
Business, Energy and Industrial Strategy (BEIS).
BEIS commissioned Frazer-Nash to explore the engineering
challenges of developing domestic appliances - gas hobs, ovens,
fires and boilers - that can run on 100 per cent hydrogen, as part
of the department's wider research into heat decarbonisation.
The appraisal investigated the impact, at a component level, of
running appliances designed for natural gas on hydrogen,
identifying the key technical issues and the components that would
need to be redesigned. It considered three potential options for
hydrogen appliances, in each case evaluating the performance,
practical considerations, development timescales and costs. The
options were:
- new appliances developed specifically to run on hydrogen
- the adaptation of existing natural gas appliances in-situ to
run on hydrogen
- new dual-fuel appliances that can switch from natural gas to
hydrogen.
In addition to a systematic review of the available literature,
Frazer-Nash undertook detailed industry engagement, including 1-2-1
conversations and a discussion workshop with appliance and
component manufacturers, gas testing bodies, maintenance and
servicing contract companies, trade associations and
consultancies.
