LAST STAGES OF TESTING: London steps ever closer to TX4 taxi Euro 6 retrofit milestone
HJS Emission Technology Ltd is edging closer to delivering a game-changing retrofit solution for London’s TX4 taxis. In an exclusive interview with TaxiPoint, Managing Director Lars Tinggaard Johannesen shared progress updates and addressed the challenges of securing approval within the capital.
The retrofit promises to be a more cost-effective option for drivers looking to extend the life of their vehicles while adhering to London’s emission standards. With the finish line in sight, all eyes are on TfL’s approval and the next chapter for London’s black cab trade.
How is the TX4 Euro 6 retrofit for London licensed taxis progressing?
We are now approaching the final part of the 10,000 miles endurance trial following a detailed schedule agreed with TfL that comprises two daily 6 hour shifts in Central London.
When do you hope the technology will be ready to enter the market and be seen on the capital’s roads?
We expect the durability trial to be completed just before Christmas, and to progress with the final emission test in January 2025. We are in close dialogue with TfL and expect to have the roll out happening shortly after.
Why has it taken so long to get this over the line in London, when it’s approved elsewhere in the UK?
HJS have received approval for taxis outside of London, with the technology considered an add on to the exhaust after-treatment already present on the TX4. TfL has taken a slightly different approach where the entire exhaust system including the original components must be changed as part of the emission upgrade, to ensure that not only the SCR catalyst added by HJS, but also that a brand new Diesel particulate filter reduces the emissions.
Further TfL had concerns related to whether the very slow-moving traffic in London would secure adequate operating conditions for the technology to work, and therefore introduced the 10,000 miles endurance trial that is a specific TfL requirement. We have demonstrated the efficiency and durability of our technology throughout the ongoing trial, but as the typical driving speed in the trial is in the range 10-15 miles/hour it takes an extended period of time to complete it.
Can taxi drivers express their interest now?
Taxi drivers are very welcome to register their interest with HJS. This will also enable HJS to give priority to taxi drivers with plates that are expiring shortly.
Are there any grants available to taxi drivers in London? If not, should more be done to support drivers wishing to upgrade their vehicles?
There are currently no grants available, but the Taxi Action Plan proposed by Neil Garret addressing the exact same problem of cab drivers leaving the trade as their plates expire, is actually calling for funding. I would think it could make sense to propose the retrofit as a cheaper alternative to what is suggested in the motion, or alternatively to be integrated in such a motion.
