NOx Sensor Network for Mobile Machinery

Since the introduction of emission tier 4, mobile machines with large diesel engines have been required to comply with significantly stricter nitrogen oxide (NOx) limits.

Adherence to these limits is generally checked at defined intervals on an engine test bench. It is necessary to determine whether an individual machine satisfies the reduced emission levels, according to requirements. The measuring equipment in general use for verifying pollutant emission levels outside laboratories is the subject of dispute. One factor that cannot be neglected is the cross-sensitivity of the sensors to such exhaust gas components as ammoniac. Cross-sensitivities can lead to erroneous results in measurements of nitrogen oxide emissions. Ammoniac is needed by modern exhaust emission aftertreatment systems that use SCR (selective catalytic reduction) technology for reducing nitrogen oxides in the catalytic converter. It is added to the exhaust gas in the form of an aqueous urea solution (AdBlue®).

The challenges accompanying the legal and political goal of lower pollutant emissions are great, and they can only be tackled by means of interdisciplinary cooperation, for instance in the field of research & development.

For this reason, research institutes and innovative companies with multiple competences have come together in the NOx-Arbeitsmobil (NOx development cluster) network. The aim is to pool their knowledge and experience to create an innovative product and service spectrum for mobile machinery based on a new principle for NOx sensors, thus making a considerable contribution to reducing pollution.

 

The Institute for light electric drives and generators (Institut für leichte elektrische Antriebe und Generatoren e. V.) (www.ileag.de) is responsible for the management of the ‘NOx-Arbeitsmobil’ network within the ZIM programme of the Federal Ministry of Economic Affairs and Energy  (BMWi) .

Fuel Cell and Hydrogen Network NRW

Fuel Cell and Hydrogen Network NRW

The Fuel Cell and Hydrogen Network NRW (Netzwerk Brennstoffzelle und Wasserstoff NRW) was founded in 2000 and is managed by the EnergyAgency. Federal State of North-Rhine-Westphalia (NRW). The network brings together experienced and new players in the fields of fuel cell and hydrogen technology, with the aim of furthering their development and marketing activities.

By intensifying the knowledge transfer between research and industry, new fields of activity can be created in companies and institutions that serve to strengthen NRW as a production and research region for fuel cell technology.

The new technology has meanwhile evolved to such an extent that it is increasingly possible to incorporate user-oriented members. The development of the network thus reflects the development of the technology.

The network’s business office has its headquarters in the state capital of Düsseldorf. There is also a branch office at the Wissenschaftspark Gelsenkirchen.

The Fuel Cell and Hydrogen Network is an integral part of the “EnergieRegion.NRW” cluster, which is managed by the EnergyAgency.NRW on behalf of the NRW Ministry for Climate Protection. The cluster is the strategic platform of the state of NRW and has broad competences in the field of energy: from energy research, technical development and market launching to energy consultation and professional further training.

The main task of EnergyRegion.NRW is to enable networking between partners in the energy sector and throughout the entire value chain. Technical innovation is promoted in the associated networks:

  • Biomass
  • Fuel cells and hydrogen
  • Energy-efficient building and solar building
  • Fuels and drives of the future
  • Power plant technology
  • Photovoltaic systems
  • Storage and networks
  • Wind energy

The cluster is supplemented in the field of science and research by the EnergyResearch.NRW cluster.

The state government has set itself ambitious climate goals. The NRW Climate Protetion Law (Klimaschutzgesetz NRW) that was passed in January 2013 provides that total greenhouse gas emissions in NRW – measured against the level from 1990 – be reduced by at least 25 percent by 2020 and at least 80 percent by 2050.

The climate protection plan is the road map for the new climate protection policy ‘Made in NRW’ and the central instrument for achieving NRW’s ambitious climate goals. The climate protection plan lays down concrete strategies and individual measures. Fuel cells and hydrogen play a major role in this context.

Carit Automotive has been a member of this network since 2016 and will play an active role in these areas.
