Perspective
On the climate impacts of blue hydrogen production
Natural gas based hydrogen production with carbon capture and storage is referred to as blue hydrogen.
Perspective
Optimising air quality co-benefits in a hydrogen economy: a case for hydrogen-specific standards for NOx emissions
Hydrogen may play a major role as an energy source to support net zero but combustion leads to emissions of NOx, a key air pollutant. Delivering optimal air quality co-benefits may need more ambitious hydrogen-specific emission standards developing.
Perspective
Responsible science, engineering and education for water resource recovery and circularity
Integration of resource recovery and circular economy concepts in higher education will stimulate responsible innovation in the water sector for an ecologically-balanced society.
Review Article

This review analyzes 53 publications that forecast battery cost and provides transparency on methodological and technological details.
Review Article
Power-to-liquid via synthesis of methanol, DME or Fischer–Tropsch-fuels: a review
A review of power-to-liquid for methanol, DME and FT-fuels focusing on commercial synthesis technologies and current power-to-liquid concepts.
Analysis
Current and future role of Haber–Bosch ammonia in a carbon-free energy landscape
The future of green ammonia as long-term energy storage relies on the replacement of the conventional CO2 intensive methane-fed Haber–Bosch process by distributed and agile ones aligned to the geographically isolated and intermittent renewable energy.
Communication
Efficiency gains for thermally coupled solar hydrogen production in extreme cold
We analyse the potential of solar hydrogen production in remote and cold world regions such as Antarctica and quantify the efficiency benefits of thermal coupling.
Paper
The role of hydrogen in heavy transport to operate within planetary boundaries
Fueling trucks with green hydrogen shows a favorable environmental life-cycle performance with respect to conventional diesel. Hydrogen as an alternative fuel would help society to safely operate within the absolute ecological limits of our planet.
Paper
Assessment of carbon dioxide removal potential via BECCS in a carbon-neutral Europe
The European technical potential for biogenic carbon dioxide removal is assessed considering seven different BECCS configurations that do not require purpose-grown bio-energy plantations.
Punching above its weight: life cycle energy accounting and environmental assessment of vanadium microalloying in reinforcement bar steel
High-strength-low-alloy reinforcement bar steels prepared by vanadium microalloying methods have the potential to dramatically reduce the embodied energy and carbon footprint of buildings.
Toxicity of exhaust particulates and gaseous emissions from gasohol (ethanol blended gasoline)-fuelled spark ignition engines
Blending of oxygenated additives with gasoline has been advocated to reduce dependence on fossil fuels and to reduce hazardous health effects of gaseous emissions and particulate matter (PM) emitted by internal combustion (IC) engines in the transport sector worldwide.
Paper
Low carbon strategies for sustainable bio-alkane gas production and renewable energy
Strategy for bio-alkane gas (propane and butane) production through the conversion of waste volatile fatty acids by bacterial cultures.
Paper
Hydrogen production from natural gas and biomethane with carbon capture and storage – A techno-environmental analysis
We quantify the technical and environmental performance of clean hydrogen production (with CCS) by linking detailed process simulation with LCA.
Energy efficiency and economic assessment of imported energy carriers based on renewable electricity
Energy and cost efficiency assessment of PtX energy carriers including long-distance distribution via ship for the import of renewable energy.
About this collection
This collection showcases some of the latest research in Royal Society of Chemistry journals on technologies to reduce greenhouse gas emissions. Greenhouse gases are significant contributors towards global climate change, therefore technologies to reduce emissions are urgently needed to address the climate emergency. We hope you enjoy reading the papers in this collection and we welcome you to submit your next paper on this theme to our journals.
