Voor emissievrije transportsector is het van belang dat bedrijven kunnen beschikken over een goed netwerk om de batterij van hun elektrische vrachtwagen op te laden. In dat kader heeft een consortium van Decisio, EVConsult en Sweco ondersteund door de Hogeschool van Amsterdam een onderzoek uitgevoerd voor het ministerie Infrastructuur en Waterstaat: “Analyse Kosteneffectiviteit Electric Road Systems (ERS) voor Nederland”. Door middel van Electric Road Systems kan de batterij van een elektrische vrachtwagen worden opgeladen tijdens het rijden, bijvoorbeeld via een bovenleiding. Het is dus een vorm van dynamisch laden, wat een alternatief voor, dan wel een aanvulling op, het stationair laden bij een laadpaal is.
The construction and transport sectors both have a substantial impact on the environment. The construction, maintaining and renovating of roads involves both these sectors and the environmental impact of this work can be reduced. The basic principle of a circular economy is to close material loops and so retain the highest utility, quality and value of products, components and materials as possible. An important question in this respect is how to qualify and quantify material flows. Material and project passports seem to be part of the solution to improve insights and sharing information on quantities and qualities of materials used in construction projects. This paper has used a literature study on material passports and has taken into account current project management software used by a municipality, in order to share a framework for organising and collecting road construction data. Furthermore, various scanning equipment and procedures were employed onsite in an experiment in collecting actual road data. This resulted in a large amount of different data files that have been interpreted and incorporated into the existing database structure of the municipality. The insights gained may help other researchers, principals and contractors in the road construction industry in collecting and storing reliable data necessary to renovate roads circularly.

The potential reduction of risk in LPG (Liquified Petroleum Gas) road transport due to the adoption of passive fire protectionswas investigated. Experimental data available for small scale vessels fully engulfed by a fire were extended to real scale road and rail tankers through a finite elements model. The results of mathematical simulations of real scale fire engulfment scenarios that may follow accidents involving LPG tankers proved the effectiveness of the thermal protections in preventing the “fired” BLEVE (Boiling Liquid Expanding Vapour Explosion) scenario. The presence of a thermal coating greatly increases the “time to failure”, providing a time lapse that in the European experience may be considered sufficient to allowthe start of effective mitigation actions by fire brigades. The results obtainedwere used to calculate the expected reduction of individual and societal risk due to LPG transportation in real case scenarios. The analysis confirmed that the introduction of passive fire protections turns out in a significant reduction of risk, up to an order of magnitude in the case of individual risk and of about 50% if the expectation value is considered. Thus, the adoption of passive fire protections, not compulsory in European regulations, may be an effective technical measure for risk reduction, and may contribute to achieve the control of “major accidents hazards” cited by the European legislation

In Nederland draaien 600.000 industriemotoren in transport, scheepvaart en z.g. Non Road Mobile Machinery (m.n. land- en bosbouw machines en stationaire motoren). Zij verbruiken jaarlijks ongeveer 5 miljard liter diesel, 20%% van het totale dieselverbruik. Ook deze sectoren dienen hun CO2 uitstoot en stikstofuitstoot te reduceren. Kijkend naar mogelijke oplossingen is elektrificatie niet geschikt vanwege het hoge specifiek gevraagde vermogen + kosten. Waterstof is te duur en voor mobiele toepassingen te bewerkelijk. Gesteund door technologie-neutraal klimaatbeleid vanuit de EU (32% hernieuwbare brandstoffen in 2030, waar elektrificatie niet mogelijk is), definieert de sector een voorkeur voor hernieuwbare methanol als marsroute richting emissiereductie. RAAK-MKB project Schoon Schip levert eind 2023 een werkend prototype methanol-conversiekit en manual voor een kleine industriemotor op. Mede door dit succes, groeide het consortium en ontstond een nieuwe vraag: Hoe kan de sector van industriemotoren lokale emissies van het huidige motorenpark van Stage III motoren naar Stage V niveau- en de Well-to-Wheel CO2-uitstoot verlagen met gebruik van hernieuwbare methanol als brandstof? De huidige stand van de techniek laat zien dat in grote (scheepvaart) motoren (<10.000Kw) dual-fuel en uitlaatgasnabehandeling vorm krijgt, voor kleinere industriemotoren is deze techniek nog nauwelijks beschikbaar. De HAN beantwoordt deze marktvraag in 4 werkpakketten om effectieve conversie van een stageIII motor naar StageV emissies te realiseren. Ze maakt hier een vertaalslag van de wetenschap en kennis bij grote zeevaartmotoren, naar (kleinere) industriemotoren. Dit gebeurt door te onderzoeken binnen welke kaders (economisch, emissies, prestaties en levensduur) een prototype motor te ontwikkelen klaar voor lange duurtesten. Brandt Schoon combineert opgedane motorenkennis met kennis uit de academische wereld om tot een betrouwbare toepassing van methanol in de binnenvaart te komen. Het gaat er om tot een werkende praktijkoplossing te komen voor het gebruik van hernieuwbare methanol in het bestaande park van 600.000 industriemotoren.
Client: Foundation Innovation Alliance (SIA - Stichting Innovatie Alliantie) with funding from the ministry of Education, Culture and Science (OCW) Funder: RAAK (Regional Attention and Action for Knowledge circulation) The RAAK scheme is managed by the Foundation Innovation Alliance (SIA - Stichting Innovatie Alliantie) with funding from the ministry of Education, Culture and Science (OCW). Early 2013 the Centre for Sustainable Tourism and Transport started work on the RAAK-MKB project ‘Carbon management for tour operators’ (CARMATOP). Besides NHTV, eleven Dutch SME tour operators, ANVR, HZ University of Applied Sciences, Climate Neutral Group and ECEAT initially joined this 2-year project. The consortium was later extended with IT-partner iBuildings and five more tour operators. The project goal of CARMATOP was to develop and test new knowledge about the measurement of tour package carbon footprints and translate this into a simple application which allows tour operators to integrate carbon management into their daily operations. By doing this Dutch tour operators are international frontrunners.Why address the carbon footprint of tour packages?Global tourism contribution to man-made CO2 emissions is around 5%, and all scenarios point towards rapid growth of tourism emissions, whereas a reverse development is required in order to prevent climate change exceeding ‘acceptable’ boundaries. Tour packages have a high long-haul and aviation content, and the increase of this type of travel is a major factor in tourism emission growth. Dutch tour operators recognise their responsibility, and feel the need to engage in carbon management.What is Carbon management?Carbon management is the strategic management of emissions in one’s business. This is becoming more important for businesses, also in tourism, because of several economical, societal and political developments. For tour operators some of the most important factors asking for action are increasing energy costs, international aviation policy, pressure from society to become greener, increasing demand for green trips, and the wish to obtain a green image and become a frontrunner among consumers and colleagues in doing so.NetworkProject management was in the hands of the Centre for Sustainable Tourism and Transport (CSTT) of NHTV Breda University of Applied Sciences. CSTT has 10 years’ experience in measuring tourism emissions and developing strategies to mitigate emissions, and enjoys an international reputation in this field. The ICT Associate Professorship of HZ University of Applied Sciences has longstanding expertise in linking varying databases of different organisations. Its key role in CARMATOP was to create the semantic wiki for the carbon calculator, which links touroperator input with all necessary databases on carbon emissions. Web developer ibuildings created the Graphical User Interface; the front end of the semantic wiki. ANVR, the Dutch Association of Travel Agents and Tour operators, represents 180 tour operators and 1500 retail agencies in the Netherlands, and requires all its members to meet a minimum of sustainable practices through a number of criteria. ANVR’s role was in dissemination, networking and ensuring CARMATOP products will last. Climate Neutral Group’s experience with sustainable entrepreneurship and knowledge about carbon footprint (mitigation), and ECEAT’s broad sustainable tourism network, provided further essential inputs for CARMATOP. Finally, most of the eleven tour operators are sustainable tourism frontrunners in the Netherlands, and are the driving forces behind this project.
To reach the European Green Deal by 2050, the target for the road transport sector is set at 30% less CO2 emissions by 2030. Given the fact that heavy-duty commercial vehicles throughout Europe are driven nowadays almost exclusively on fossil fuels it is obvious that transition towards reduced emission targets needs to happen seamlessly by hybridization of the existing fleet, with a continuously increasing share of Zero Emission vehicle units. At present, trailing units such as semitrailers do not possess any form of powertrain, being a missed opportunity. By introduction of electrically driven axles into these units the fuel consumption as well as amount of emissions may be reduced substantially while part of the propulsion forces is being supplied on emission-free basis. Furthermore, the electrification of trailing units enables partial recuperation of kinetic energy while braking. Nevertheless, a number of challenges still exist preventing swift integration of these vehicles to daily operation. One of the dominating ones is the intelligent control of the e-axle so it delivers right amount of propulsion/braking power at the right time without receiving detailed information from the towing vehicle (such as e.g. driver control, engine speed, engine torque, or brake pressure, …etc.). This is required mainly to ensure interoperability of e-Trailers in the fleets, which is a must in the logistics nowadays. Therefore the main mission of CHANGE is to generate a chain of knowledge in developing and implementing data driven AI-based applications enabling SMEs of the Dutch trailer industry to contribute to seamless energetic transition towards zero emission road freight transport. In specific, CHANGE will employ e-Trailers (trailers with electrically driven axle(s) enabling energy recuperation) connected to conventional hauling units as well as trailers for high volume and extreme payload as focal platforms (demonstrators) for deployment of these applications.
