Spain-headed Qualitas Energy Private Equity, S.G.E.I.C., S.A (Qualitas Energy), a global investment and management platform focused on renewable energy, energy transition, and sustainable infrastructure investment, has announced it is investing in biomethane aka renewable natural gas (RNG) through its Qualitas Energy Fund V.
Founded in Spain in 2006, Qualitas Energy has a robust track record of investing in Spain’s energy transition, starting with its initial fund Fotowatio Renewable Ventures, followed by its second fund, Vela Energy, and continuing with the Qualitas Energy Fund IV.
This new operation marks Qualitas Energy’s reentry into the Spanish market and represents its first venture into renewable natural gas (RNG) investment within the country.
A 1 TWh per annum RNG project pipeline
At EUR 2.4 billion, Qualitas Energy Fund V stands as the largest private equity fund in Spain and one of the most significant in renewable energy across Europe.
The initial projects have already entered preliminary approval stages and are anticipated to become operational between 2027 and 2028.
Collectively, these projects are set to deliver a production volume of approximately 1 TWh per year, equivalent to the average annual natural gas consumption of over 120,000 households, significantly reducing carbon dioxide (CO2) emissions.
Álvaro Pérez has been appointed as Director of Renewable Gases to lead this new business venture.
With over 15 years of industry experience, he brings valuable expertise to the company and will be backed by a team of seasoned professionals with deep expertise in the development, design, and construction of renewable energy assets.
Complement UK RNG project portfolio
In 2022, Qualitas Energy acquired a controlling stake in Acorn Bioenergy, a British company specializing in the production of RNG and biogenic CO2 through the upgrading of biogas generated in anaerobic digestion (AD) facilities.
Currently, Acorn Bioenergy has a portfolio of 14 AD projects, with construction already underway for two of them.
Once fully commissioned Acorn Bioenergy is expected to become a leading RNG and green-CO2 platform in the UK.
Qualitas Energy is also exploring investment opportunities in RNG across other regions where it has business operations.
