Reducing carbon footprint in cities: Natural gas-based energy generation with zero CO2 emission

This work proposes a novel zero–CO2–emission energy system to meet thermal and electrical energy needs of the cities without emitting CO2 while using natural gas as a primary energy source. Since the system uses available technologies, it is envisioned as a part of transition towards net-zero sustainable economy. At the core of the system is production of hydrogen via pyrolysis of methane which has recently achieved technological maturity of …
