Gianni, Marco (author), Pietra, Andrea (author), Coraddu, A. (author), Taccani, Rodolfo (author)The International Maritime Organization (IMO) has recently discussed the introduction of a new design index called the Carbon Intensity Indicator (CII), which is a measure of the total carbon dioxide emissions divided by the amount of cargo carried and by the distance travelled on a one-year basis. In this study, authors have analysed a cruise...journal article 2022

Shikhar, Utkarsh (author), Hemmes, Kas (author), Woudstra, T. (author)Fuel cells are electrochemical devices that are conventionally used to convert the chemical energy of fuels into electricity while producing heat as a byproduct. High temperature fuel cells such as molten carbonate fuel cells and solid oxide fuel cells produce significant amounts of heat that can be used for internal reforming of fuels such...journal article 2021

Jaspers, B. C. (author), Kuo, P.C. (author), Amladi, Amogh (author), van Neerbos, Wouter (author), Aravind, P.V. (author)Negative emission technologies have recently received increasing attention due to climate change and global warming. One among them is bioenergy with carbon capture and storage (BECCS), but the capture process is very energy intensive. Here, a novel pathway is introduced, based on second-generation biofuels followed by carbon circulation in...journal article 2021

Cavalli, A. (author), Aravind, P.V. (author)Contaminants as particulate matter, sulfur, chlorine and tar should be removed from biosyngas to avoid damaging solid oxide fuel cells. However, there is no sufficient information on tar effect since they might be potentially used as a fuel, or they might cause performance losses and irreversible damages. Therefore, this study aims to assess...journal article 2021

Cinti, G. (author), Bidini, G. (author), Hemmes, Kas (author)Solid oxide fuel cell systems for combined heat and power production (SOFC μCHP) fueled by natural gas are attractive because of their high electrical and total efficiency even at small scale. The development of a hydrogen economy will increase the availability of distributed hydrogen as a pure gas. Alternatively, hydrogen may be blended with...journal article 2019

Recalde Moreno Del Rocio, M.D.R. (author), Woudstra, T. (author), Aravind, P.V. (author)Nowadays, there is worldwide interest in diversifying energy supply. In this regard, biomass is the best possible renewable organic substitute for fossil fuels. In particular, the energy content of very wet biomass, recovered with appropriate technology, could potentially be used for power generation. In addition to power generation, this...journal article 2019
