Mapfre, Abante Launch €100M Iberian Biomethane Fund

A significant new investment vehicle focused on the burgeoning biomethane sector across the Iberian Peninsula has been established, aiming to raise €100 million. This initiative is a joint effort by Spanish insurance giant Mapfre, independent financial group Abante, and energy advisory firm IAM Carbonzero. The fund, named Bioenergy Agro Iberia FCR, marks the second collaboration between these entities, building on the momentum of their prior success in renewable energy investments.

The strategic expansion to encompass both Spain and Portugal highlights the growing recognition of biomethane's critical role in Europe's decarbonization objectives. Biomethane, a renewable gas produced from organic waste streams such as agricultural residues and animal manure, offers a direct substitute for natural gas and can be integrated into existing gas networks, utilized for power generation, or serve as a sustainable fuel for transportation. The sector is experiencing robust growth, driven by supportive regulatory frameworks and increasing demand for low-carbon energy solutions.

This new fund follows the highly successful debut vehicle, MAPFRE Energías Renovables II FCR. That initial fund, which closed in mid-2025, surpassed its €100 million target, securing approximately €110 million. It attracted a diverse base of 146 investors, including substantial contributions from Spain's state-owned ICO bank, which provided €20 million via European Next Generation funds, and a direct investment of €20 million from Mapfre itself. The success of the first fund underscores strong investor confidence in the biomethane asset class and the expertise of the managing partners.

Bioenergy Agro Iberia FCR is designed to deploy capital across a varied portfolio of biomethane production facilities throughout Spain and Portugal. Beyond the core production of biomethane, the fund's investment strategy extends to associated value chain activities. This includes the management of biofertilizers and biocompost derived from the anaerobic digestion process, optimization of logistics for feedstock and finished products, and the capture and commercialization of CO₂ for applications such as greenhouse cultivation. This integrated approach aims to maximize returns and environmental impact.

With a projected lifespan of 12 years, extendable to 15, and an initial investment phase of five years (potentially extending to seven), the fund targets a net internal rate of return (IRR) exceeding 12%. This financial objective is underpinned by the anticipated significant increase in biomethane capacity. The previous fund was projected to facilitate the development of 20-25 biomethane plants, contributing substantially to Spain's installed capacity and creating numerous permanent and indirect employment opportunities.

The advisory services for Mapfre in establishing this second fund were provided by international law firm Addleshaw Goddard, reflecting the increasing sophistication of legal and structural considerations in renewable energy finance. Mapfre, a leading Spanish insurer, continues to bolster its alternative investment portfolio, while Abante, an independent financial group managing approximately €10 billion, brings extensive client and asset management experience. IAM Carbonzero provides specialized technical and market expertise crucial for navigating the complexities of the biogas and biomethane production sector.
