About Us

Solas Capital is a European investment specialist dedicated exclusively to project debt for energy efficiency and behind-the-meter assets. Based out of Zurich, Munich and Dublin, we bridge the funding gap between institutional investors and the energy transition’s most cost-effective pillar: building decarbonisation.

Unlike traditional renewable energy investments, which finance new supply, we finance the reduction of energy demand at scale. This creates an attractive investment proposition for liability-driven institutional investors: contracted cash flows from essential energy infrastructure — backed by an EU credit loss guarantee and independent of electricity prices.

At Solas Capital, we firmly believe that the best energy is the one we don’t use. 

Our Founders

The Origin Story

Solas Capital was founded in 2018 by Sebastian Carneiro and Paul Kearney, who identified a critical yet underserved niche in traditional project finance. With their combined expertise in renewable energy and energy efficiency, they recognised three emerging trends:

  • demand-side efficiency would be equally crucial to achieving net zero as renewable generation
  • these distributed projects required a standardised portfolio approach and
  • the growing “energy-as-a-service” business model needed specialist financing solutions.

Pioneering Energy Efficiency Finance

The founders built Solas Capital to bridge the gap between institutional investors and high-impact energy efficiency projects, with a particular focus on the building sector—responsible for 40% of Europe’s energy consumption. Their vision is clear: mobilising institutional capital to enable zero-upfront cost energy efficiency projects is essential to accelerate adoption and meet our climate goals.

Both Sebastian and Paul firmly believe we can only reach net-zero if energy transition solutions are the most convenient and cost-effective options available. They recognise that innovative finance plays the pivotal role in removing cost barriers, transforming sustainability from an aspirational goal into the default practical choice.
