TLDR
A new approach for the use of methane as energy source is developed, after thermal methane cracking, only the energy content of the hydrogen is used and the carbon is stored safely and retrievably in disused coal beds.Abstract:
Despite a rising output, in the last few decades the known reserves of fossil energy resources have steadily increased. Additionally, there are in all likelihood tremendous reserves of methane hydrate. In view of the climate change, new means must be explored for its use as an energy source. Starting with an assessment of various options for dealing with the carbon cycle and thermodynamic considerations of methane chemistry, a new approach for the use of methane as energy source is developed in this Concept. After thermal methane cracking, only the energy content of the hydrogen is used and the carbon is stored safely and retrievably in disused coal beds. Arguments for the viability of a carbon moratorium of this kind are discussed.read more

Levelized cost of CO2 mitigation from hydrogen production routes
TL;DR: In this paper, the relative costs of carbon mitigation from a life cycle perspective for 12 different hydrogen production techniques using fossil fuels, nuclear energy and renewable sources by technology substitution are examined, and the results show that there is a tradeoff between the cost of mitigation and the proportion of decarbonization achieved.

TL;DR: In this article, the authors compare the current best practice steam methane reforming (SMR) with potential pathways for low-CO2 hydrogen production, including electrolysis coupled with sustainable renewable electricity sources, reforming of hydrocarbons coupled with carbon capture and sequestration (CGS), and thermal dissociation of hydrocarbon into hydrogen and carbon (pyrolysis).

TL;DR: A unique temperature-dependent approach is described that confers on a microorganism (the archaeon Pyrococcus furiosus, which grows optimally on carbohydrates at 100°C) the capacity to use carbon dioxide, a reaction that it does not accomplish naturally.

Journal ArticleDOI
Financial and Ecological Evaluation of Hydrogen Production Processes on Large Scale
TL;DR: In this article, a cross industry development of methane pyrolysis was initiated, and the carbon footprint of the new technologies was evaluated using a system extension and differential methods, which yielded very good values for product cost and carbon footprint.

TL;DR: In this paper, the relationship between the amount of N fixed by chemical, biological or atmospheric processes entering the terrestrial biosphere, and the total emission of nitrous oxide (N2O), has been re-examined, us- ing known global atmospheric removal rates and concentra- tion growth of N2O as a proxy for overall emissions.
