Combined heat and power (CHP) production in buildings is one of the mitigation options available for achieving a considerable decrease in GHG emissions. Micro-CHP (mCHP) fuel cells are capable of cogenerating electricity and heat very efficiently on a decentralised basis. Although they offer...

Hydrogen energy systems (HES) are increasingly recognized as pivotal in cutting global carbon dioxide (CO2) emissions, especially in transportation, power generation, and industrial sectors. This paper offers a comprehensive review of HES, emphasizing their diverse applications and economic...

A trial to quantify CO2 emission by utilizing our belonging materials has been conducted. For the Polymer electrode membrane Fuel Cell (PEFC) system, the reduction of more than 23% CO2 emission was measured under a practical operation in a family of Okayama prefecture. The statistical data of...
