Due to the recent heatwave the UK has been experiencing, the nation has reached new records in its solar power industry.

With cloudless days, solar power briefly became the country’s number one source of power, ahead of gas, the Guardian reported.

On Sunday 24 June, solar power generated more than 27% of the UK’s grid for approximately one hour.

Despite the lack of investments going into the renewable energy recently, solar power reached its highest ever weekly output in the nation at 533GWh.

In the review period – between 21 and 28 June – five of the seven days saw solar energy generate more than 75GWh, breaking another record.

Also, for the first time ever in the UK, solar energy created more than 8GW of power each day for eight consecutive days.

“During the past 12 months alone, we have seen renewable generation records broken and we expect this trend to continue, as technology advances and we find new ways to accommodate and manage more wind and solar power on our network,” stated Duncan Burt, the National Grid’s Director of System Operations, the Guardian claimed.

“This marks the start of subsidy-free solar being economically viable, and I genuinely believe we’ll see bigger changes to the electricity sector in the next 10 years than we’ve seen in the past 10,” noted Dr Alastair Buckley, solar expert at the University of Sheffield, the Guardian added.

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.
