HJS at busworld EUROPE KORTRIJK: cleaner buses for better air

Menden, September 2017 – Bus routes criss-cross every neighbourhood of our towns and cities, but not all of the buses servicing them are clean. Germany’s federal government has decided to invest a billion euros in order to reduce levels of nitrogen oxide (NOx) emissions. Retrofitting SCR systems is both ecologically worthwhile and economically smart. HJS’s technology is capable of removing almost all nitrogen oxides from diesel exhausts.

  • HJS has its own stand at busworld 2017 in Kortrijk/Belgium
  • Retrofitting SCR technology in city buses
  • Technically autarkic system, available with no wait
  • System has proven itself to be highly efficient in everyday real-life operation (RDE)

Dieselgate, EU infringement proceedings against Germany and suits filed by environmental and conservation organisations complaining of massive immission levels – there appears to be no end to the stream of negative headlines attacking diesel. In order to avoid driving bans for diesels, the federal government intends to invest a billion euros in local authorities’ battle against high NOx levels. One key to a cleaner future is to retrofit diesel-powered commercial and municipal vehicles – and particularly public transport buses – with a SCR system. That retrofitting with such an autarkic system is economically attractive and ecologically potent is something HJS is demonstrating at the busworld EUROPE trade fair in Kortrijk/Belgium (20 - 25 October 2017).

The German government decided at the beginning of September to further boost the level of its funding of retrofit measures for municipal fleets. Priority is to be given to those cities in which NOx levels are especially high.

Effective pollutant reduction

The modular system developed by HJS removes almost all nitrogen oxides (NOx) from diesel exhaust emissions. The optimisation of exhaust emissions treatment systems for inner-city operation and the use of state-of-the-art technologies make a huge difference. In real-life operation (as tested under the new RDE (Real Driving Emissions) cycle), HJS systems prove to be extremely efficient and reliable. What’s more, they’re available right now. Retrofitting public transport buses is a particularly effective measure, because these vehicles are underway in our cities the whole day, every day. Add to this the fact that in light of the threat of driving bans, public transport is set to become even more important in future. As a result, cities are called upon to use vehicles that are equipped with the very latest emissions technology and are as clean as possible.

From an economic point of view, more than 40 buses already in service on our roads can be retrofitted for the price of just one new electric bus. Roughly 80 per cent of regular public service buses in Germany do not yet comply with the Euro VI emissions standard – but all of them capable of being retrofitted with SCR. In particular, Euro IV, V and EEV vehicles can be retrofitted with this system. NOx emissions can be reduced by up to 95 per cent in real day-to-day operation.

And there are already some interesting flagship projects underway in Europe to retrofit PSVs. Major cities such as Berlin, Madrid and London are turning to clean buses – and therefore to a cleaner future for their city centres and their citizens. Trailblazer in Germany is the capital city and its Berliner Verkehrsbetriebe (BVG). And London, in particular, has already implemented a range of measures aimed at improving air quality. 1,000 systems from HJS have already been supplied and installed.

Thanks to the positive experiences gained to date in London, the city will be retrofitting a further 5,000 buses with SCR de-NOx systems over the coming two to three years. The expertise of the emissions specialist and the “Made in Germany” quality of its emissions treatment systems have won the day: HJS is one of the select group of suppliers whose technology has been approved by Transport for London (TfL). To this end, the UK government is providing a sum of £78m (around €89m).

Monitoring emissions

Another advantage of the HJS system is that the city buses will be equipped with what the company calls “NOx TV monitoring”. With the aid of a telematics app, the emissions of each bus can retrieved remotely at any time and in real time. What’s more, the data collected is made available in a cloud, listed separately for each bus.

The retrofitting of thousands of public service buses with highly effective technologies is a milestone along the path to a cleaner, healthier future. Detailed information about the technology for public transport is available at busworld EUROPE from 20 - 25 October 2017 in Kortrijk/Belgium. You will find HJS in Hall 8 on Stand 870.
