About Us
At Solas Capital, we provide specialised financing solutions for demand-side energy projects, bridging the gap between institutional investors and high-impact energy efficiency and behind-the-meter projects.
Unlike traditional renewable energy investments that focus on supply, we specialise in reducing energy demand at scale—an often-overlooked but equally important pillar to reach Net-Zero. We are based in Zurich, Munich and Dublin and operate across Europe.
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.
