We believe that the Energy Transition only will succeed with the integration of innovative and efficient Energy Storage Technologies.
LOMARTEC
combines the best of two grid scale Energy Storage Technologies in one Hybrid System. We store and re-supply on demand surplus electricity from the grid, any available renewable and irregularly supplied energy, like from PV or Wind and we utilize ambient temperatures and waste heat as energy sources and store them as electric power.
Problem Statement*
There have been up to 301 hours of negative prices on the German EPEX•market
That means there is an OVERSUPPLY of green electricity on the market
In those cases, solar and wind farms are often being CURTAILED ('shut down')
In 2023 curtailment led to an irreversible loss of 19 TWh in Germany
The Heat Planning Act is getting far behind its 2030 targets
What if residual and ambient heat could be tapped and stored?
Today's industry leaves waste heat with a saving potential of 5 billion € a year
Leaving a potential of 70 TWh/a plus emission reductions of 20 mt of C02

* Example for Germany only, applicable worldwide

lntroduction - Hybrid Energy Storage System HESS
LOMARTEC's grid scale Hybrid Energy Storage System (HESS) combines an Advanced Compessed Air Energy System (A-CAES) with a DUAL Battery Energy Storage System (D-BESS).
HESS stores Energy when it is available in abundance or when it is not needed at the time. lt delivers power on demand within milliseconds.
lt is the only hybrid storage system combining the following energies:
- Ambient heat (10°C - 70°C)
- Wasted heat (10°C - 70°C, optional up to 150°C)
- lrregularly supplied power from PV or Windfarms or other VRE
- Regularly supplied surplus power from the grid
- Heat from isothermal compression (up to 150° C)
- Potential of high pressure (up to 500 bar) to low pressure (3 - 5 bar)
- High torques generated by compressed air
- High speeds without reducing the torques

LOMARTEC's Business Models
HESS, for the Stabilization of the Grid
- Hardware, Software, Services.
Example: 100 MW / 800 MWh
HESS in an underground
tunnel conflguration,
lifetime 50 years,
ROI 6-12 years
HESS, as Integration in lndustries
- Hardware, Software, Services.
Example: 1 MW / 8+MWh
HESS on ground,
ROI 3-4 years
HESS, optimizing Renewable Assets
- Hardware, Software, Services.
Example: 10 MW / 80 MWA
HESS on ground,
ROI 4-6 years
Only in Co-operation with selected partners
- Power Arbitrage (Direct Marketing).
- Long Term PPA agreements with own or assigned HESS units.
- Storage-as-a-Service (SaaS).

Example: DUAL-BESS attached to 30 GWh solar farm:
- One DUAL-BESS 20-foot container cost: € 295,000
- One DUAL-BESS 20-foot container can store: 8 MWh
- Per day it needs to store: 6.6 MWh
(8% curtailment per year) - Per year it needs to store: 2,400 MWh
- Average EPEX-price: € 95,- / MWh
- The value of one day storage is: € 627
- The value of one year storage is: € 228,855,-
- One DUAL·BESS 20-foot container will have earned itself back in 1.3 years.
- Since DUAL BESS can transform ambient temperatures of 10°C - 70°C and store it as electricity, the ROI will even be shorter.
Business Case
The German market (DENA}:
- Wind Energy Output in 2023: Approximately 162,060 GWh
- Solar Energy Output in 2023: Approximately 65,548 GWh
- In total there has been generated 227.608 GWh (227,608,000 MWh) on renewable electricity in Germany >8% ofthese renewable sources were curtailed in 2023, equal to 19,000,000 MWh (19 TWh) of electricity being lost forever
- The monetized value of this was equal to € 1.8 billion per year (average EPEX-price of € 95.18/MWh in 2023)
- The targetted LCOS of our solution is, depending on the no. of cycles, € 30.- / MWh
- Asset owners would have earned at least€ 65.- / MWh by using our solution (NET)
- OR: They could have earned € 1.235 billion per year (saved)

Market Opportunity
50 billion US$ per year
The global market for Leng Duration Energy Storage (LDES) is estimated tobe US$ 50 billion per year and forecast to grow significantly with a cumulative investment of up to US$ 3 trillion by 2040.
Source: PV Magazine USA {26.09.2023) based on statements from US DoE and McKinsey & Co.
69 billion US$ this year
The global market for waste heat recovery or prevention is expected to exceed 69 billion US$ this year, growing at a CAGR of 7%.
63% of the waste heat temperatures are <100°C.

"To me this looks very interesting, because we have a huge quantity of residual heat, which is produced in all our activities. Yet we need to buy a lot of electricity. So, if it was feasible to produce electricity out of heat that would be indeed of high interest."
Felix Amberg, President AMBERG GROUP
