For energy consultants
The option still missing from your list of variants.
Your clients are asking about net zero. Here is the answer.
Dezentrale Multi-Energie-Systeme // DMES
Advising fully means knowing every option.
Emissions reduction pathway, self-consumption, the winter gap. Your clients expect energy concepts that think beyond heat pumps, PV and batteries. Battery storage covers day-night balancing; for seasonal shifting there has so far been no variant that can be implemented in an occupied building. The reference work “Areale und Quartiere” (ed. Gugerli, 2024) places seasonal energy storage with hydrogen. The solar obligation and the negative feed-in prices to be expected from 2027 make storage a mandatory component of every larger PV installation. That very option now exists as a plannable system.
Facts you can verify yourself.
A DMES stores surplus electricity as hydrogen in metal hydride, as a solid at just 35 bar, and returns it as electricity and heat. It is the only large-scale storage system permitted inside an occupied building. The world's first installation has been running at full load in Eich LU since April 2024 and supplies operating data, design values and a referenced safety concept in accordance with SVGW H10001. Your independence remains untouched. We work without commissions and without referral models. You receive data and technical basics; the recommendation remains yours.

Facts to run the numbers on.
Since April 2024
Operating data instead of brochures. The installation in Eich LU runs at full load and can be visited.
SVGW H10001
Referenced safety. The technical bulletin for building-integrated H₂ systems, co-authored by eRevo.
1000 t CO2
Funding leverage for your clients. The emissions reduction pathway is met measurably. From around 1000 tonnes of CO2 per year, state funding instruments become available.
70 to 90 %
Self-consumption within a ZEV. Achievable in mixed-use developments (“Areale und Quartiere”, 2024).
Under 10 years
Payback possible, under ideal conditions.
> 75 %
Overall efficiency. With coupled use of electricity and heat.
Never recommend anything unverified. So verify us.
We supply the basis for your own assessment. Design values, operating data from live operation, profitability calculations and the underlying standards. Not a sales dossier, but material whose numbers you can check yourself.
What your consultancy gains from it.
The answer that others do not have.
Anyone who knows long-duration storage inside buildings and can calculate it wins mandates for emissions reduction pathways and site energy concepts that would otherwise go to large planning firms.
New follow-on mandates.
Every DMES assessment generates consultancy work. Comparison of variants, support during the potential analysis and review of the funding instruments.
A partner who respects your role.
eRevo supplies system architecture and facts; the advising is yours. Delivered by the pioneer of decentralised multi energy systems in Europe, eRevo AG Energy Revolution.
