Enerhack

What Enerhack does

Enerhack is a Tallinn, Estonia-based energy education organization founded in 2021, operating through two legal entities: MTÜ Enerhack Foundation (non-profit, Reg. 80597147) and Enerhack OÜ (for-profit). The company delivers free energy education programs for youth aged 7–18, including summer and winter energy camps (600+ children per summer), the KidWind Challenge wind turbine design competition, EnerHäkaton hackathons, school energy curricula for grades 5–12, workshops, and facility excursions — all primarily delivered at the Tallinn University of Technology (TalTech) campus. For professionals, Enerhack offers an online e-academy (enerhack.courses) carrying 45+ affordable courses covering energy storage, hydrogen engineering, geothermal energy, wind power, district heating/cooling, HVAC engineering, and waste-to-energy, delivered by 150+ lecturers and industry experts with recognized certificates upon completion.

The commercial business model blends professional course fees, multi-tier event sponsorships (KidWind Challenge Gold €5,000 / Silver €2,500 / Bronze €1,000), and significant EU grant funding. The organization is participating in two major EU-funded R&D and training consortia: CommitClimate (€2.42M budget, January 2023–December 2025, 27 partners across the Baltic Sea region) developing a CO2 simulator platform for municipal climate planning, and Skills4DHC (8 partners across 7 EU countries) producing 13 tailored training programs for the District Heating and Cooling workforce. The technology stack is modest: a web-based e-academy for course delivery, an open-source Enerhack heating-cost calculator launched in March 2023, and the in-progress CommitClimate digital platform. The customer base includes named enterprise clients (Adven, Fortum, Euroheat & Power), academic partner TalTech, and public sector stakeholders (British Council, EU Interreg programs, Estonian municipalities), with 6,000+ total participants across 30+ countries. Awards include the 2024 Estonian Science Popularization Award from the Ministry of Education and Research.
