Top down system The current electricity grid architecture is reaching its limitations of transport capacity
Electricity grid designed as top down system
Top down system
Feed electricity from one central grid and divide A problem on the grid affects all subsequent links Intensifying the grid to meet the current demand requires approximately 10 years The grid is not suitable for absorbing strong fluctuations in the supply of green energy, which will only increase in the future Decentralized energy hubs

Balanced hubs in practice Example of what a society with multiple balanced energy hubs could look like
• Connect energy producers and consumers on the lowest level possible • Local energy storage for day/night, but also seasonal storage • Exchange of energy only for balancing purposes

10
Introduction to Iron Power Renewable energy storage and transportation in a circular value chain 1
Energy production • Energy production using renewable energy sources • Energy (electricity) is converted into hydrogen in order to prepare for reduction
3
2
Reduction a • Reduction of iron oxide powder to store energy
4
2 1
• Reduction creates iron powder from iron oxide powder • To start reduction-oxidation cycle, material is brought in upfront, after which it can be used for 10-100 cycles
6
b • Future potential to use direct electrolysis for reduction, skipping
the need for hydrogen production
3
Transport and storage of iron powder • Transport and storage of iron powder to transfer energy
4
Oxidation
5
• Release of (heat) energy by oxidation of iron powder • Produces high output temperature (>1500°C) Return transport and storage of iron oxide powder
5
• Return flow of iron oxide powder to complete cycle 6
End-usage • Potential for high-grade heat industry usage, centralized energy generation, district heating and hydrogen production

Why Iron Power Key advantages of Iron Power
CO2
%
Carbon free
Low NOx
Safe and compact
Circular
Cost competitive
No CO2 emissions
Up to 90% less NOx emissions compared to fossil fuels
Not explosive nor toxic and a high volumetric energy density
Iron powder is used in a circular way
Compared to alternative green energy carriers

Impact Beleid • Ultra-lage Nox • CO2-vrij • Circulair • Geen zeldzame aardmetalen
Techniek • Disruptief: schaalbaar • Kennis: Koploper wereldwijde R&D • Excellente aanvulling op NL’se H2 inzet en infrastructuur.
Economisch • Logistiek: Kans om hub-functie in droge bulk te behouden (Rotterdam en Amsterdam) • Vestigingsklimaat: Stabiele energieprijs, • Veiligheid: niet explosief, niet giftig, makkelijk transporteerbaar • Diversificatie energiemix = risico-mitigatie • Bedrijvigheid voor maak/installatie industrie • Internationalisatie: export product
Maatschappelijk • Zelfde comfort als fossiel: waar en wanneer we willen • Kostenzekerheid voor woon- en werkomgevingen • Eenvoudige veilige decentrale opslag mogelijk • Vermindert belasting op reeds gespannen netinfrastructuur, helpt transitie te versnellen • Wereldwijde impact

Output
Levelized cost of energy
LCOE [€/MWh]
• Economic model for cost assessment • Based on value chain specified by over 90 input parameters • 20 year period • 3.2% required return to capital • Only green energy input • Piped H2 not feasible due to relatively low energy demand and large distance to backbone • Emission allowances from CO2 reduction can reduce LCOE • Subsidy options for several value chain steps
