About This Fund
CI Advanced Bioenergy Fund I (CI ABF I) is an infrastructure fund managed by Copenhagen Infrastructure Partners (CIP), one of the world's largest renewable energy infrastructure fund managers headquartered in Copenhagen, Denmark. The fund held its first close at EUR 375 million in April 2022 and reached its final close at EUR 750 million in October 2023. It is classified as a dark green investment fund under the EU Sustainable Finance Disclosure Regulation (SFDR) Article 9, reflecting its strict sustainability mandate. The fund is structured to allow institutional investors — including pension funds, life insurance companies, sovereign wealth funds, family offices, and asset managers — to contribute to the energy transition by investing in advanced bioenergy infrastructure assets.
CI ABF I pursues an equity investment strategy focused on industrial-scale biomethane and advanced biofuel production facilities. The fund exclusively uses sustainable feedstock — including agricultural biowaste, waste wood, household biowaste, and industrial biowaste — to produce clean energy products such as biomethane (renewable natural gas), bio-LNG, and second-generation bioethanol. This strategy targets the decarbonization of hard-to-abate sectors including heavy transport, shipping, and industrial heating. The fund's assets are designed to integrate directly into existing natural gas infrastructure, providing flexible grid-compatible clean energy at scale.
By December 2025, CI ABF I had made four Final Investment Decisions and committed over 80% of its capital, with operational and development-stage projects located across Denmark, Spain, Belgium, Finland, and the United Kingdom. CIP manages more than EUR 30 billion in AUM across its full fund family, which includes the flagship CI series (CI IV, CI V), the Energy Transition Fund, and multiple thematic funds. CI ABF I is part of CIP's expanding thematic infrastructure strategy, which complements its flagship offshore wind funds with focused plays on bioenergy, energy storage, and transmission infrastructure.
