For energy consultants
The option is still missing from your list of variants.
Your clients are asking about net zero. Here is the answer.
Dezentrale Multi-Energie-Systeme // DMES
Advising means knowing every option.
Emissions reduction pathway, self-consumption, and the winter gap. Your clients expect energy concepts that look beyond heat pumps, PV and batteries. Battery storage covers day-to-night balancing, while seasonal shifting has so far lacked an option that can be implemented inside an occupied building. The reference work “Areale und Quartiere”, edited by Gugerli in 2024, identifies hydrogen as an option for seasonal energy storage. The solar obligation and expected negative feed-in prices from 2027 make storage an increasingly important component of every PV installation. That option now exists as a system than can be planned and assessed.
Facts you can verify yourself.
A DMES stores surplus electricity as hydrogen in metal hydride, in solid form at up to 35 bar and returns it as electricity and heat. It is the only large-scale storage system that is allowed inside an occupied building. The first installation in the world has been operating 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 or referral models. You receive the data and technical basis, while the recommendation remains yours.

Facts on which to run the numbers.
Since April 2024
Operating data instead of brochures. The installation in Eich LU operates at full load and can be visited.
SVGW H10001
Referenced safety. The technical bulletin for building-integrated H₂ systems was co-authored by eRevo.
1,000 tonnes CO2
Funding leverage for your clients. The emissions reduction pathway is met measurably. From around 1,000 tonnes of CO2 per year, state funding instruments may become available.
70 to 90%
Self-consumption within a ZEV. Such rates may be achievable in mixed-use developments according to “Areale und Quartiere”, 2024.
Under ten years
Payback possible, under ideal conditions.
More than 75%
Overall efficiency with coupled use of electricity and heat.
Never recommend anything unverified. Verify us first.
We provide the basis for your own assessment, including design values, operating data from live operation, profitability calculations and the underlying standards. This is not a sales dossier, but material whose figures you can validate.
What your consultancy gains from it.
The answer that others do not have.
Those who understand long-duration storage inside buildings and can calculate it can win mandates for emissions reduction pathways and site energy concepts that might otherwise go to large planning firms.
New follow-on mandates.
Every DMES assessment can generate consultancy work, including variant comparisons, support during the potential analysis and review of funding instruments.
A partner who respects your role.
eRevo supplies system architecture and facts. The advice remains yours. Delivered by eRevo AG Energy Revolution, the pioneer of decentralised multi-energy systems in Europe.
