We are delighted to announce a landmark accomplishment by our Technical Advisory Team, marking a significant stride in renewable energy finance and engineering.

Our team has concluded a series of technical and financial red flag reports, coupled with exhaustive technical due diligence for a sophisticated merger and acquisition (M&A) transaction. This project was notable for its integration of an expansive portfolio of hybrid projects, uniting Photovoltaic (PV) systems with groundbreaking green hydrogen technology, stationed in Spain. The portfolio's cumulative capacity assessment exceeding 4,000 MW denotes a crucial milestone in our advisory endeavors.

This initiative's integration of green hydrogen technology into the portfolio underscores an innovative approach to renewable energy. Leveraging electricity from PV systems to electrolyze water, green hydrogen emerges as a versatile, sustainable energy vector with significant potential to decarbonize various sectors, including transportation and industrial processes. The synergy between solar energy and hydrogen production epitomizes a promising avenue toward a sustainable and resilient energy future.

Under Bluetree's leadership, our advisory panel exhibited its expertise in the technical and financial evaluation of the projects assessed. The team's proficient project management, effective client coordination, and seamless integration with client financial and technical teams were commendable. The due diligence process included a detailed technical review of the PV and green hydrogen assets, assessing their operational viability and examining critical financial models. Furthermore, the team conducted:

  • Site Analysis for the Electrolyzer: Investigating the availability of essential resources like water and electrical grid access, crucial for hydrogen production and complementing the renewable asset's output.

  • Technology and Hydrogen Production Strategy Analysis: Ensuring the conceptual design and inputs are in harmony with anticipated hydrogen production and fulfilling the offtaker's needs or desired product output.

  • Permit Analysis: Thorough analysis of permits necessary for installing and operating the renewable asset and its hybridization with hydrogen production.

  • Renewable Asset Energy Generation Analysis: Verification that the renewable asset's energy generation (solar) aligns with the project's strategic needs. This includes analyzing the integration with energy from a green Power Purchase Agreement (PPA) if required, ensuring adherence to the criteria for classifying the hydrogen produced as green hydrogen.

  • Financial Model Inputs Analysis: Validation that the financial model's inputs for CAPEX, OPEX, and production are within the expected ranges for the chosen technology and strategy.

  • Hydrogen Sales Model Analysis: Evaluation of various product output options, considering the potential needs for compression, storage, or pipeline access dedicated to the offtaker.

This achievement accentuates our team's significant expertise and dedication to facilitating complex transactions within the renewable energy sector, establishing our position as a reliable partner for clients steering through the complexities of renewable energy projects and investments.

We congratulate our professionals for their exceptional work and steadfast commitment to driving renewable energy solutions forward, significantly contributing to the transition towards a more sustainable energy landscape. 🏆👏
