The hoot might just be a reality...not trigen but a PEM fuel cell. Totally different application. Each to their respective niches.
"Construction has begun on a flexible microgrid that features energy sources available today, including a 230-kW solar photovoltaic system, a 1-MW stationary proton exchange membrane (PEM) fuel cell generator, 325-kW solid oxide fuel cell (SOFC), and an onsite 500-kWh battery energy storage system. The microgrid is designed to support the campus' energy needs, allowing it the ability to operate off-grid. The system is expected to be fully operational by 2026."
However, Toyota and FuelCell Energy have established a long term relationship as Toyota has signed on with FuelCell to receive Tri-gen products under a 20-year purchase agreement.
