Investing in the
energy transition
Delta is a private equity advisory boutique sourcing, structuring and investing in energy-transition opportunities that are cheaper than fossil alternatives or represent the lowest-cost route to decarbonisation.
We are a Swiss-based investment and advisory firm. We invest our own capital, often alongside professional investors, and work directly with management teams on strategy, financing and growth.
Meet the teamOur Investment Themes
We develop investment themes as markets, technology and economics evolve. The five below reflect our current focus across the energy transition.
Battery Energy Storage Systems
Grid-scale storage and enabling infrastructure that improves system flexibility and supports greater renewable penetration.
Biogas & Biomethane
Biogas and biomethane from organic feedstocks, with capture-ready biogenic CO₂ creating a natural link to CCUS.
Biocarbon
Renewable carbon products that displace fossil carbon in steel, metals and other high-temperature industrial processes.
Electrification
Technologies and infrastructure that replace fossil-fuelled processes with efficient electric alternatives across industry, transport and buildings.
Carbon Capture, Utilisation & Storage
Capture, transport, utilisation and permanent storage infrastructure supporting industrial decarbonisation and durable carbon removal.
Our Portfolio
We have constructed a portfolio spanning early-stage through to mature energy-transition businesses, with investments across three of our five current themes in the UK, Europe, the US and Africa.
Explore portfolioInvestment Rationale
We build each investment rationale around a clear commercial case. Policy, carbon markets and regulation can strengthen returns, but the underlying business or project must stand on its own.
Energy-transition relevance
Businesses and projects with a direct role in decarbonising power, fuels, industry or the carbon cycle.
Mid-to-mature stage
We generally favour opportunities that have moved beyond concept stage and have tangible assets, operating evidence or a credible path to build-out.
Clear commercial use case
Identifiable customers, real end-markets and products or infrastructure solving a defined commercial need.
Value beyond capital
Situations where Delta can contribute through structuring, financing, commercial development, governance and hands-on operating support.
Scale & standalone economics
Credible routes to growth with attractive unit economics and a base case that does not depend on subsidy or policy support.
