ZE-Gen

What ZE-Gen does

ZE-Gen (Zero Emission Generators) is a collaborative, cross-sector initiative launched at COP27 in November 2022 and co-convened by the Carbon Trust and Innovate UK. Its mission is to accelerate the displacement of fossil fuel generators with renewable energy-based alternatives in low- to lower-middle-income countries across Sub-Saharan Africa, South Asia, and the Indo-Pacific, where more than 1.5 billion people face unreliable electricity access and an estimated 25 million generators are deployed. ZE-Gen operates as a portfolio of funding programmes rather than a single product company: a £10.8m Technology Accelerator (Discover, Lift-off, Flight phases) backing feasibility, industrial research, and demonstration; a £2m Demonstrator competition supporting scale-up of innovations such as Aegis Energy (wind generators for e-mobility in Côte d'Ivoire and Fiji) and BioLite (expandable solar generators for Nigerian SMEs); a Circularity Challenge (e.g., the $50,000 CoolCycle winner repurposing disused generators into solar cooling for Nigerian farmers); the Green Genset Facility providing inventory finance to MSME solar distributors; and a Demand Generation programme funding awareness campaigns. Underlying technology focus spans solar, batteries/chemical storage, wind, thermal storage, hydrogen, compressed air, and integrated wind/solar/battery systems, with several projects incorporating IoT, smart metering, digital-twin battery monitoring, and AI/ML for energy management.

ZE-Gen's business model is grant-funded development finance rather than commercial sales. It has catalysed more than £50.5m in support against a stated £100m ambition, anchored by the UK Government's Ayrton Fund (managed by FCDO, DESNZ, and DSIT, part of the UK's £11.6bn International Climate Finance 2021–2026) and the IKEA Foundation, with additional backing from the Climate Emergency Collaboration Group. ZE-Gen acts as a coalition orchestrator: it does not build, own, or sell the end-products, but instead deploys grants and convenes a delivery network — including A2EI (PROSPECT data platform, solar systems), Open Capital (market analysis), GOGLA and VeraSol/CLASP (sector advocacy and quality assurance), Intellecap (Asia-Pacific research), Integrate to Zero (philanthropic insights), and a growing roster of project partners across Nigeria, Philippines, Côte d'Ivoire, Fiji, South Africa, Malawi, and Uganda. The go-to-market is event-driven and community-led, structured around open competitions, multi-stage accelerators, and demand-generation campaigns with named Phase 1 contract sizes of £40k–£60k and matched Phase 3 deployment funding of up to £2.4m.

The addressable market ZE-Gen targets is substantial: an estimated $28–50bn is spent annually on generator fuel globally, with Nigeria alone spending ~$8bn per year, 41 million Nigerian SMEs relying on fossil generators, and 17 million Nigerian households affected — generating 550 MtCO2e of projected cumulative emissions 2021–2030 and an estimated 1,500 deaths per year in Nigeria from generator smoke inhalation. ZE-Gen targets four customer segments — households, MSMEs, healthcare/education institutions, and agricultural/e-mobility use cases — across seven+ countries, with quantitative targets including 500,000 litres of diesel displaced annually per implementation and the displacement of millions of fossil fuel generators over time. Leadership comprises Lily Beadle as Programme Director and Dr James Coombs O'Brien as ZE-Gen Lead at Innovate UK.

Revenue model

1. Grant Funding and Development Finance: ZE-Gen operates as a multi-stakeholder initiative funded by government aid programs and philanthropic foundations. Initial commitment of over £19 million with ambition to scale to £100 million. Funding sources include UK Government Ayrton Fund, IKEA Foundation, Climate Emergency Collaboration Group, and other development partners. The initiative mobilizes financing and investment, catalyzing concessional finance, commercial debt, equity, and climate finance to the sector.
2. Green Genset Facility Financing: A funding instrument providing financing to solar generator distributors (particularly MSMEs) to support inventory procurement. ZE-Gen invested £250,000 into the GGF alongside existing funders BGFA, DOEN Foundation, Good Energies Foundation, IKEA Foundation, NEFCO, Open Capital, and Sida. The facility addresses working capital gaps for distributors to purchase stock and serve customers.

Core offering

ZE-Gen is a collaborative, cross-sector initiative that runs grant-funded programs to accelerate the replacement of fossil fuel generators with renewable energy-based alternatives (solar generators, battery storage, wind, hybrid solutions) in low- and lower-middle-income countries. It delivers this through technology accelerator competitions, demonstrator funding, demand generation campaigns, distributor financing, and circularity/end-of-life programs targeting sub-Saharan Africa, South Asia, and Indo-Pacific regions.

Product overview

ZE-Gen (Zero Emission Generators) is a collaborative, cross-sector initiative led by the Carbon Trust and Innovate UK to accelerate the replacement of polluting fossil fuel generators with renewable energy-based alternatives in low- to lower-middle-income countries across Sub-Saharan Africa, South Asia, and the Indo-Pacific. Rather than a single product company, ZE-Gen operates as a portfolio of funding programs and initiatives including: the £10.8m Technology Accelerator (supporting feasibility to commercialization in Nigeria and Philippines), the £2m Demonstrator (testing scalability of innovations), the Circularity Challenge (addressing generator end-of-life), the Green Genset Facility (providing inventory financing to distributors), and the Demand Generation project (driving market adoption through awareness campaigns). ZE-Gen also supports and funds technology projects such as Aegis Energy's wind-generator systems for e-mobility, BioLite's expandable solar generators, and CoolCycle's generator repurposing solutions, while utilizing tools like A2EI's PROSPECT data platform for market intelligence.
