BREAKTHROUGH OFFSHORE ENERGY STORAGE

OLTAEN SP. Z O.O. - BREAKTHROUGH OFFSHORE ENERGY STORAGE

COMPANY: OLTAEN Sp. z o.o, Warsaw, Poland. STAGE: Pre-seed, TRL 3. SECTOR: Renewable Energy Infrastructure and Energy Storage.

FUNDING SOUGHT: 2-3M EUR pre-seed round.

THE PROBLEM WE ARE SOLVING: As offshore wind capacity scales toward 500 GW globally by 2035, the industry faces a critical bottleneck - affordable long-duration energy storage. Current battery solutions cost 250-400 USD per kWh for offshore applications and require replacement every 10-15 years. This creates a massive cost barrier for grid-scale renewable energy deployment, particularly in emerging markets. The global offshore energy storage market represents a 50+ billion USD opportunity by 2040.

OUR SOLUTION - OAPS TECHNOLOGY: OLTAEN has developed Offshore Accumulating Power Station (OAPS), a revolutionary mechanical energy storage system that uses Archimedes buoyancy force to store energy. By controlling the submersion and release of massive floating structures in seawater, we convert electrical energy to mechanical potential energy and back.

KEY PERFORMANCE METRICS: 70% COST ADVANTAGE - 180-220 USD per kWh versus 250-400 USD per kWh for batteries. 3X LONGER LIFESPAN - 30+ years versus 10-15 years for batteries. COMPARABLE EFFICIENCY - 80-85% round-trip efficiency. SCALABLE CAPACITY - 220 MWh per installation with modular design. ZERO CRITICAL MINERALS - No lithium, cobalt, or rare earth dependencies.

COMPETITIVE ADVANTAGE: Patent applications filed for core mechanical systems and control algorithms. Validated computational fluid dynamics models. 11 proprietary configuration variants for different depth and capacity scenarios. Fundamental physics advantage - mechanical simplicity beats electrochemical complexity on cost. NON-COMPETING with battery giants - we target offshore and coastal niche where batteries underperform. SUPPLY CHAIN INDEPENDENCE - uses commodity materials like steel and concrete plus standard marine engineering. EUROPEAN IP plus ASIAN

CURRENT STATUS: COMPLETED - Hydrodynamic modeling and validation at TRL 3. Techno-economic analysis showing 70% cost advantage. Market assessment across 3 continents. Patent strategy developed. Initial conversations with Chinese manufacturing partners. NEXT 18 MONTHS with funding - 1:10 scale prototype in controlled marine environment. Marine engineering partnership for detailed design. Grid integration studies with offshore wind developers. Pilot project agreement with European offshore wind farm. Series A preparation with proven prototype performance.

WHY INVEST IN OLTAEN: MASSIVE MARKET - Offshore wind is fastest-growing renewable sector. FUNDAMENTAL COST ADVANTAGE - 70% cheaper changes project economics. MULTIPLE REVENUE PATHWAYS - Equipment sales, technology licensing, platform repurposing, O&M services. DE-RISKED PHYSICS - Archimedes principle is 2300 years proven, execution risk only. STRATEGIC PARTNERSHIPS - Chinese manufacturing plus European wind developers in development. STRONG IP POSITION - Early-mover advantage in emerging technology category. ESG ALIGNMENT - Enabling renewable energy transition with sustainable materials.

USE OF FUNDS (2-3M EUR): 40% prototype engineering and construction. 25% marine testing facilities and validation. 15% IP protection and regulatory approvals. 10% partnership development in China and with offshore wind developers. 10% team expansion including marine engineers and business development.

BUSINESS MODEL: Revenue from equipment sales to offshore wind developers, technology licensing to regional manufacturers, joint venture partnerships for platform repurposing projects, and long-term operations and maintenance service contracts.

WHY NOW - MARKET TIMING: Offshore wind deployment accelerating to 500+ GW by 2035. Battery costs plateauing due to materials constraints. Growing demand for supply chain diversification post-2022 energy crisis. Chinese manufacturers seeking European IP partnerships. EU Innovation Fund actively supporting breakthrough energy storage with 3 billion EUR available.
