A new LED headlamp has been developed that combines high-level luminance with low energy use and could be a game-changer for electric and other next-generation vehicles.

The issue of energy consumption in electric vehicles, combined with limited availability of charging stations, has long been an issue for next-generation cars.

However, Toyoda Gosei has created an LED lamp that could help solve at least part of this problem and it is expected to come into widespread use in the future.

Using the blue LED crystal growth technology developed by the manufacturer over many years, Toyoda Gosei has improved the structure of gallium nitride crystals in the light source with flip-chip technology for good heat dissipation.


In future, these new LED lamps, which, according to tests, can generate a high luminance of 2,300lm could be used in next-generation vehicles, which reports suggest could become a drain on power as they grow in popularity.

According to the National Grid’s Future Energy Scenarios report, the number of plug-in cars and vans in the UK, for example, could reach nine million by 2030, an increase on the current figure of 90,000.

The National Grid expects energy use to grow greatly alongside electric cars

With growing demand for environmentally friendly cars expected to rise worldwide, the knock-on effect on electricity consumption is clear.

Toyoda Gosei’s new LED headlamp is the sort of innovation that will be essential for energy provision to keep up with the rise in demand for electric vehicles.

Trafigura and Yara International explore clean ammonia usage

Commodity trading company Trafigura and Yara International sign MoU to explore developing ammonia as a clean fuel in shipping

Independent commodity trading company Trafigura and Yara International have signed an MoU to explore developing ammonia as a clean fuel in shipping and ammonia fuel infrastructure.

Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050. 

How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.

Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:

  • The supply of clean ammonia by Yara to Trafigura Group companies
  • Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
  • Development of new clean ammonia assets including marine fuel infrastructure and market opportunities

Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.  

There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.

Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.

Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.

Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.

It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
