Hydrogen is fit for long-haul vehicles because of the short refueling time and long range of using hydrogen as onboard storage instead of batteries. Meanwhile, hydrogen can also be used for long-time grid energy storage because of the low material cost and low self-discharge. By using fuel cell electric vehicles (FCEVs) for energy generation, the fuel cells (FCs) in idle FCEVs can be connected to the grid (FCEV2G) and supply electricity to the grid by consuming hydrogen stored in a station. In this way, the hydrogen usage in the transportation and energy storage sectors can be synergically integrated. A mixed integer linear programming (MILP) model is established to simulate and evaluate the economic and environmental potential of the operation of a FCEV2G station. The station's profit and carbon emission reduction potential depend on the traffic and electricity profiles. It is estimated that a net profit of 233,976 USD can be generated and simultaneously 210 tonnes carbon emissions can be reduced, using the historic traffic and electricity data of Alberta. Furthermore, considering the Canadian carbon tax in the optimization increases the net profit and carbon reduction to 246,704 USD and 377 tonnes, respectively. Meanwhile, using electricity data with lower carbon intensity and less fluctuation, e.g., that in Ontario, significant technological improvements are needed to make the FCEV2G station operation economically viable. These results demonstrate the potential of FCEV2G in generating monetary incentives and environmental benefits by integrating the transportation and energy storage sectors.</div></div>","PeriodicalId":100356,"journal":{"name":"DeCarbon","volume":"7 ","pages":"Article 100096"},"PeriodicalIF":0.0,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143150530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With DWC systems installed on roadways, they constitute a charging infrastructure or electrified roads (eRoads) that have many advantages. For instance, the large battery size of heavy-duty EVs can significantly be downsized due to charging-while-driving. However, a high power demand of the DWC system, especially during traffic rush periods, could lead to voltage instability in the grid and undesirable power demand curves. In this paper, a model for the power demand is developed to predict the DWC system's power demand at various levels of EV penetration rate. The DWC power demand profile in the chosen 550 km section of a major highway in Canada is simulated. Solar photovoltaic (PV) panels are integrated with the DWC, and the integrated system is optimized to mitigate the peak power demand on the electrical grid. With solar panels of 55,000 kW rated capacity installed along roadsides in the study region, the peak power demand on the electrical grid is reduced from 167.5 to 136.1 MW or by 18.7 % at an EV penetration rate of 30 % under monthly average daily solar radiation in July. It is evidenced that solar PV power has effectively smoothed the peak power demand on the grid. Moreover, the locally generated renewable power could help ease off expensive grid upgrades and expansions for the eRoad. Also, the economic feasibility of the solar PV integrated DWC system is assessed using cost analysis metrics.</div></div>","PeriodicalId":100356,"journal":{"name":"DeCarbon","volume":"7 ","pages":"Article 100092"},"PeriodicalIF":0.0,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143150528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
