Day 3 of the Energy Web Dive 2025 was all about breakthrough projects in decarbonization and renewable energy. Ioannis Vlachos kicked off the day by providing an update on Energy Web’s Horizon Europe proposals, spotlighting initiatives such as community-integrated PV systems and measures to boost renewable energy adoption. Frederik Jacobsen then followed with his introduction of Katalist, a maritime Book & Claim registry that leverages tokenized emissions reductions to overcome traditional fuel models and scale maritime decarbonization. Both sessions clearly reflected Energy Web’s drive to harness digital innovations and foster collaborations that push us toward a decentralized, low-carbon future. Here are the key takeaways from Day 3.
SESSION 1
Energy Web’s New Horizon Europe Proposals
Speaker: Ioannis Vlachos
Title: Commercial Director, EMEA at Energy Web
Topic: Participation in Horizon Europe Research Proposals
Context & Challenges
Energy Web has submitted two proposals under the Horizon Europe initiative, launched by the European Commission to support clean energy innovations. The proposals aim to accelerate community-based photovoltaic (PV) systems and enhance the market uptake of renewable energy technologies. Energy Web has a strong track record in European-funded projects, with seven active projects totaling over €3.5 million in funding. Evaluation results for the proposals are expected by July or August 2024.
Proposal 1: Innovative, Community-Integrated PV Systems
-
Topic ID: HORIZON-CL5-2024-D3-02-06
-
Total Budget: €5M (shared among consortium partners)
-
Objective: Facilitate large-scale deployment of community-integrated PV systems, extending from domestic and commercial installations to utility-scale implementations.
Key Expected Outcomes:
-
Boost PV Profitability: Enhance profitability and adoption of PV systems within renewable energy communities.
-
Empower Clean Energy Communities: Engage local communities through energy cooperatives and decentralized digital platforms, leveraging Energy Web’s expertise in blockchain-based solutions.
-
Community-Aggregated Energy Solutions: Deploy advanced planning tools, peer-to-peer trading, self-consumption models, and robust cybersecurity measures.
Proposal 2: Market Uptake Measures of Renewable Energy Systems
-
Topic ID: HORIZON-CL5-2024-D3-02-10
-
Total Budget: €2M
-
Objective: Improve adoption and develop market frameworks for renewable energy systems across industrial, residential, and energy sectors.
Key Expected Outcomes:
-
Increase Renewable Adoption: Aim for higher renewable energy consumption by 2030.
-
Enhance Market Development: Establish financial incentives and effective policy tools to support scalable clean energy models.
-
Improve Social Acceptance: Foster a positive perception of renewable energy technologies and support their widespread adoption.
Scope & Innovation:
The proposal will address renewable energy markets broadly while targeting specific sectors (electricity, heating, cooling, renewable fuels) and geographic contexts (urban and peri-urban areas) to develop long-term, replicable solutions.
Outlook
Energy Web is optimistic about these proposals and looks forward to collaborating with the European Commission to accelerate the transition toward a decentralized, clean energy future. Updates on the evaluation process are expected later this summer.

SESSION 2
Speaker: Frederik Jacobsen
Title: Head of Katalist
Topic: Katalist and Energy Web – Enabling Maritime Decarbonization
Context & Challenges
The maritime industry faces a critical challenge: while shipping companies consume fuel, they are not always directly linked to cargo owners willing to pay a premium for low-emission transport. Traditional emissions reduction approaches tie sustainable marine fuel (SMF) adoption to physical availability, limiting scalability. This creates inefficiencies and slows down the decarbonization process.
Solution – Katalist and the Book & Claim Model
The Book & Claim model allows shipping companies using sustainable marine fuels to tokenize their verified emissions reductions. These digital tokens or certificates can then be claimed by cargo owners, decoupling the emissions benefits from physical fuel constraints. This mechanism increases market efficiency, expands access to low-emission shipping, and accelerates maritime decarbonization.
To support this system, Katalist was launched on November 14, 2024, as an industry-wide, non-profit Book & Claim registry. The platform was co-developed and tested with 29 industry participants across the maritime value chain, including container operators, shipowners, fuel suppliers, cargo owners, and regulatory bodies. The goal was to ensure usability, credibility, and trust from the outset.
Key Components of Katalist
-
Registry
-
Developed by Energy Web Foundation
-
Captures, verifies, and tokenizes emissions reduction data from voyages using Sustainable Marine Fuel (SMF)
-
-
Documentation
-
Defines participation rules, verification standards, and legal requirements
-
Ensures clarity in emissions accounting and reporting
-
-
Landing Page
-
Provides public access to registry documentation and industry updates
-
Serves as a hub for participants to track, verify, and engage with Katalist
-
Governance & Trust Mechanisms
Katalist’s credibility and ease of use rely on three core principles:
-
Governance Structure
-
Operates as a not-for-profit registry
-
Future changes in design and methodology are reviewed by an Expert Committee of industry leaders and non-profits
-
-
Uniform, Verified Data
-
All claims are based on actual voyage data, independently verified by third parties
-
Standardized formats enhance comparability and simplify emissions reporting
-
-
Transparent Methodology
-
Publicly accessible data verification protocols, emissions calculations, and legal terms of use
-
Reinforces trust among industry stakeholders
-
Outlook
Katalist represents a transformative step in maritime decarbonization. By combining decentralized technologies with an industry-wide registry, it enables a scalable, verifiable, and transparent Book & Claim system. This approach enhances accountability, attracts sustainable fuel investments, and accelerates the industry's transition to low-carbon operations.
The collaboration between Katalist and Energy Web has been instrumental in bringing this vision to life.
