Hydrogen to Power: Exploring Current Developments and Future Challenges

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
As the interest in low‐carbon energy systems grows, hydrogen continues to attract attention as a flexible energy carrier for power applications. Developments in hydrogen production, storage, transport, and utilization are explored. In addition, the deployment challenges of hydrogen energy vector related to economics, infrastructure, safety, and ...

Reducing Nitrous Oxide Emissions Associated With Fertiliser Using Nitrogen Enriched Biochar

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 4, July–August 2026.
ABSTRACT There is a need for agricultural practices that decrease nitrous oxide emissions while sustaining yields for food production. In the current paper, we investigate the possibility of reducing emissions by co‐applying or enriching biochar with mineral nitrogen and using it as a fertiliser.

Enhanced Biomethane Recovery From Source‐Separated Cow Urine via Co‐Digestion With Waste Paper

open access: yesGCB Bioenergy, Volume 18, Issue 7, July 2026.
This study outlines the experimental process where cow urine, collected from a dairy barn equipped with a source‐separating manure system, and waste paper are loaded into bioreactors (CU0–CU50) at varying ratios to analyze the biogas yield. The analytical results highlight that this collection system significantly enhances biogas and biomethane ...

Finding a mix of renewable energy for different stakeholders by applying multi‐criteria decision‐making techniques

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 4, Page 2499-2534, July 2026.
Abstract This paper presents a two‐stage model for planning a renewable energy portfolio by balancing economic, social and environmental sustainability goals. The first stage addresses a multi‐objective problem where conflictive impacts generated by the energy portfolios should be optimised according to the corresponding economic, social or ...

Biotechnological intensification of biogas production [PDF]

open access: possibleApplied Microbiology and Biotechnology, 2007
The importance of syntrophic relationships among microorganisms participating in biogas formation has been emphasized, and the regulatory role of in situ hydrogen production has been recognized. It was assumed that the availability of hydrogen may be a limiting factor for hydrogenotrophic methanogens.

Biogas Production in Africa

2011
Biogas is derived from anaerobic digestion of biomass, which can be broadly grouped into municipal sewage and solid waste (including food wastes), livestock and agroprocessing residues, and energy crops. Technologies range in scale from domestic systems for thermal (cooking) energy to multi-megawatt grid-connected combined heat and power generation ...

Biogas Production Systems

2018
Biogas, a mixture of methane and carbon dioxide, is produced by anaerobic digestion of organic waste. Municipal and agroindustrial organic wastes are important feedstocks for producing biogas. Anaerobic digestion is a microbial process. It not only reduces the amount of waste to be disposed, but the methane produced can be burnt as fuel to provide ...
