Clean Hospital Energy Systems
Newdigit Created a Clean Energy Solution for Hospitals in Nigeria
Colin Smith — December 3, 2025
Newdigit has deployed its Just Add Water modular system in Lagos hospitals to provide continuous clean electricity, medical‑grade oxygen, and potable water by combining solar power with PEM electrolyzer and fuel cell technology.
Newdigit’s Just Add Water system integrates a solar array, a proton exchange membrane electrolyzer, and a PEM fuel cell to produce hydrogen, oxygen, and electricity on site. The packaged units are described as delivering 12 to 15 kW of continuous clean power, 10 to 40 litres per day of medical‑grade oxygen, and recoverable clean water as a by‑product, with a plug‑and‑play design intended for rapid installation and scaling. Initial installations are operating in three hospitals in Lagos, serving more than 24,000 patients annually, and are expected to generate about 274 MWh of clean electricity in the first year while avoiding over 150 tonnes of CO₂ emissions annually. The project includes training for hospital staff and local technicians to support operation and maintenance and to promote local ownership and sustainability of the systems.
The deployment is funded through the Powering Healthcare Innovation Fund, which selected Newdigit as one of three grantees from an 84‑applicant cohort and provided a USD 50,000 grant to implement the demonstration installations. Newdigit positions the technology as a multi‑service solution that addresses unreliable grid supply and diesel generator dependence by combining generation, oxygen production, and water recovery in a single modular package. Management has stated a scaling objective to reach 1,000 hospitals in Nigeria by 2030, framing the initiative as a pathway to improve clinical outcomes and facility resilience while reducing operational emissions and fuel costs. The project’s broader implications depend on replication at scale, availability of financing for wider rollouts, and continued capacity building to ensure long‑term operation and integration with health system logistics and supply chains.
