PrePower Booster integrates a green‑hydrogen fuel‑cell generator with a variable‑capacity heat pump to produce up to 10 kW of thermal energy and 3 kW of electricity, delivering high‑temperature space and water heating while supplying on‑site power that eases grid peaks. The plug‑and‑play system retrofits existing boiler connections for single‑family homes to multi‑unit buildings, enabling low‑carbon heating upgrades for contractors, utilities and developers across Europe.

Problem
Heating accounts for nearly half of global energy consumption, with space and water heating in buildings representing a major source of carbon emissions. Existing heat‑pump solutions are limited by low ambient temperatures and insufficient electricity capacity, making it difficult to replace natural‑gas boilers in many residential and commercial settings. Consequently, the transition to carbon‑neutral heating is slowed, and electricity grids experience peak‑load stress.
Solution
Prelectron’s PrePower Booster combines a hydrogen‑fuel‑cell generator with a conventional heat‑pump system to deliver both high‑temperature heat and on‑site electricity from a renewable source. The fuel cell burns green hydrogen to produce thermal energy and electrical power, which the heat pump then upgrades to temperatures suitable for space and water heating. By supplying electricity locally, the Booster reduces demand on the distribution grid and mitigates peak‑load spikes. The integrated system can be retrofitted to existing boiler infrastructure, enabling a faster shift away from natural‑gas heating in residential and small‑commercial buildings. Its modular design supports scaling from single‑family homes to multi‑unit complexes, aligning with regional decarbonization targets while maintaining overall system efficiency.
Target Audience
The primary customers are residential heating contractors, utility companies, and property developers seeking to retrofit or upgrade building heating systems with low‑carbon, grid‑supportive solutions across Europe.
