The German engineering and electronics multinational, Bosch, announced its new diesel developments at its annual press conference.

The company has refined existing technologies around the fuel that could see vehicle manufacturers reducing nitrogen oxide (NOx) emissions enough to meet future targets set for 2020.

Currently new vehicles are not permitted to emit more than 168mg per kilometre. This will be reduced to 120mg by 2020.

With Bosch’s new technology, vehicles are achieving an emission of as little as 13mg – approximately 10% of the target set for two years’ time.

“Bosch is pushing the boundaries of what is technically feasible,” stated Dr Volkmar Denner, CEO of Bosch.

“Equipped with the latest Bosch technology, diesel vehicles will be classed as low-emission vehicles and yet remain affordable.”

Bosch has developed technologies that focus on the temperature of the fuel in order for vehicles to run more efficiently.

“We call our system active thermal management because it keeps the most important part of the diesel exhaust, the exhaust gas recirculation (EGR) system, running at its optimal temperature,” Michael Krüger, Diesel Division Development Boss at Bosch, informed Autocar.

“If you were to coast or not touch the accelerator, the EGR would cool far below its optimum temperature, so NOx levels are higher.”

“With our system, the point is to minimise all temperature losses by packaging the EGR as close to the engine as possible.”

The company is also working on incorporating artificial intelligence (AI) into combustion engines, aiming for the technology to allow the engines to produce no significant particulate or NOx emissions.

 “There’s a future for diesel. Today, we want to put a stop, once and for all, to the debate about the demise of diesel technology,” stated Denner at the press release.

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
