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...

The success of climate and natural resource protection depends amongst others on the expansion of renewable energies. The policy paper describes the central results of the RESCUE study as well as the challenges and steps required to expand renewable energies in order to achieve greenhouse gas...

The sustainable energy transition taking place in the 21st century requires a major revamping of the energy sector. Improvements are required not only in terms of the resources and technologies used for power generation but also in the transmission and distribution system. Distributed generation...

Unlike oil and coal, which are compressed forms of energy, renewable energy requires unusually large land areas. This article calculates the consequences of a switch to hydrogen-cell vehicles powered by electricity from wind turbines. It then re-does the calculation for three other green energy...

This paper analyses the impact of supply technology choices and costs on structures and prices on the emerging low-carbon hydrogen market using a novel, integrated natural gas and hydrogen market model. It shows that natural gas-based low-carbon hydrogen production pathways predominate in...

The transition of a sector from a pollutant state to a clean one is studied. A green technology, subject to learning-by-doing, progressively replaces an old one. The notion of abatement cost in this dynamic context is fully characterized. The theoretical, dynamic optimization, perspective is...
