What Renetech does
Renetech is a renewable energy consultancy and project developer founded in 2005, operating through two entities — Renetech AB (Stockholm, Sweden) and Renetech Bioresources Ltd (Dublin, Ireland) — with a headcount of 1–10 employees. The firm's functional focus is on renewable energy technologies and project development, spanning hydropower, solar thermal cooking, bioenergy and briquetting, biogas, and waste-to-energy. Its primary geographic orientation is Sub-Saharan Africa, complemented by activity in European Union markets, with active partnerships in Uganda (Fourways Group, since 2010), Kenya (Ecobora Ltd, since 2020), and Tanzania (TechBridge Invest AS, NORAD-funded).
The company's most distinct technology is an Institutional Solar Thermal Stove, which was awarded the Solar Impulse Foundation Efficient Solution Label in 2020. Renetech also serves as the Irish National Team Leader for IEA Bioenergy TCP Task 39 (since October 2023), contributing to international bioenergy value-chain research. Technical leadership is provided by CEO Tom Walsh and CTO David Bauner, supported by a small engineering team that includes recent hire Chloe Champlong (January 2025).
Renetech's business model is project-based and grant-dependent: revenue is generated through development-finance-backed project execution (e.g., the NORAD-funded NOK 25M / USD 2.4M Tanzania biogas initiative) and technology advisory engagements with in-country partners. The firm monetizes its technical and regulatory credentials (Solar Impulse Label, IEA participation) to secure consortium positions within donor-funded programs rather than selling standardized products at scale, leaving revenue tied to a small number of multi-year anchor engagements.

Products and services
- Institutional Solar Thermal Cooking Stove A solar thermal cooking solution adapted for Kenyan schools and institutions. It claims four times greater efficiency than solar panels in collecting solar radiation and uses heat storage plus gravity-fed heat transfer, so no batteries are required, enabling cooking before sunrise and after sunset.
- Cooking Energy Briquettes from Agricultural Waste Solution for producing briquettes from sustainably produced biomass — agricultural waste, agroforestry waste, and dedicated grass crops — to reduce deforestation and provide an alternative cooking energy source. Developed with partners in Uganda.
- Small Hydropower Development Development of small-scale hydropower projects, including on-site river flow measurement and feasibility assessment for electricity generation in regions such as Rwanda.
- Biofuel Production Consulting Consultancy services for the biofuel industry, including assessment of support requests and evaluation of biofuel production potential for clients such as the Tanzania biofuel industry assessment.
- Charcoal Value Chain NAMA Development Development of Nationally Appropriate Mitigation Actions (NAMA) for the charcoal sector to support sustainable charcoal production and reduce deforestation. Commissioned by UNDP for the Kenya context.
- Renewable Energy Market Studies Comprehensive renewable energy market potential and energy efficiency studies for public-sector and donor clients, including the widely-cited Tanzania renewable energy market development study.
