In this paper we show for the first time the feasibility of ammonia exhaust gas reforming as a strategy for hydrogen production used in transportation. The application of the reforming process and the impact of the product on diesel combustion and emissions were evaluated. The research was started with an initial study of ammonia autothermal reforming (NH3 e ATR) that combined selective oxidation of ammonia (into nitrogen and water) and ammoni Read More

This article presents findings from a representative survey fielded through the Norwegian Citizen Panel examining public perceptions of hydrogen fuel and its different production methods. Although several countries including Norway have strategies to increase the production of hydrogen fuel our results indicate that hydrogen as an energy carrier and its different production methods are still unknown to a large part of the public. A common misunderstandi Read More

Alternatives to cope with the challenges of high shares of renewable electricity in power systems have been addressed from different approaches such as energy storage and low-carbon technologies. However no model has previously considered integrating these technologies under stability requirements and different climate conditions. In this study we include this approach to analyse the role of new technologies to decarbonise the power system. The Read More

This paper reviews the relationship between the production of steel and the environment as it stands today. It deals with raw material issues (availability scarcity) energy resources and generation of by-products i.e. the circular economy the anthropogenic iron mine and the energy transition. The paper also deals with emissions to air (dust Particulate Matter heavy metals Persistant Organics Pollutants) water and soil i.e. with toxicity ecotoxicity epidemi Read More

Hydrogen has set high hopes for decarbonization due to its flexibility and ability to decarbonize sectors of the economy where direct electrification appears unviable. Broad hydrogen policies have therefore started to emerge. Nevertheless it is still a rather niche technology not integrated or adopted at scale and not regulated through particular policy provisions. The involved stakeholders are thus still rushing to set the agenda over the issue. All this plays ou Read More

A numerical study was conducted to investigate the effects of hydrogen and scavenging air temperature (SAT) on the combustion and emission characteristics of a 2-stroke heavy-duty dual-fuel (DF) marine engine at full load. The engine had a 700 mm bore fuelled with hydrogen–methane (H2-CH4) mixtures. Three-dimensional simulations of the combustion and emission formation inside the engine cylinder with various H2 contents in the H2-C Read More

The Government is committed to developing the UK’s low carbon hydrogen economy: hydrogen is considered critical to delivering energy security and our decarbonisation targets and presents a significant growth opportunity. It can play a pivotal role in our transition to a future based on renewable and nuclear energy while ensuring that natural gas used during this transition is from reliable sources including our own North Sea production and can provide Read More

Today with the increasing transition to electric vehicles (EVs) the design of highly energy-efficient vehicle architectures has taken precedence for many car manufacturers. To this end the energy consumption and recovery rates of different powertrain vehicle architectures need to be investigated comprehensively. In this study six different powertrain architectures—four independent in-wheel motors with regenerative electronic stability contr Read More

The intermittent nature of renewable energy resources such as wind and solar causes the energy supply to be less predictable leading to possible mismatches in the power network. To this end hydrogen production and storage can provide a solution by increasing flexibility within the system. Stored hydrogen as compressed gas can either be converted back to electricity or it can be used as feed-stock for industry heating for built environment Read More

Decarbonisation will need a significant societal shift. The when why and how we travel is going to look very different within a decade. Joining us is Florentine Roy – a leading expert on electric vehicles and Innovation Project Lead at UK Power Networks and Matt Hindle - Head of Net Zero and Sustainability at Wales and West Utilities. Let’s talk about the energy system implications of this massive undertaking and how it can be enabled by innovation in a fair an Read More
