Clean Edge released its U.S. Clean Tech Leadership Index this week, with California and its major cities taking home many of the top spots.

While the data used for compiling the report covers more than 70 different indicators, it falls mainly in three categories: technology, policy, and capital. The report is split in half, with both a state and metro index.

For the states, California held the number 1 spot by a wide margin. The state scored a 93.7 overall, beating the next closest state (Massachusetts) by 14.3 points. The report calls California’s prominence “broad and deep” as it finishes first in all three of its subcategories for clean tech deployment. The only thing keeping California from winning the index’s “triple crown” is its close second finish in the policy and capital areas.

Second place Massachusetts is also ahead of the pack by a wide margin, with third place Oregon 12.4 points behind it. From there, however, things even out, as less than 10 points separate the 3rd through 10th place states.

California’s clean tech prominence is also displayed via its cities, which make up half of the top 10. San Francisco, San Jose, and San Diego were the top 3, with Sacramento and Los Angeles taking the number 5 and 7 spots, respectively. San Francisco remains a strong leader, with its leadership score of 94.4, a full 17.7 points over runner-up San Jose.

The big movers in California were San Diego and Los Angeles, with the former gaining 4 spots, and the latter losing three. The index cited San Diego’s resilience and commitment to clean tech despite political turmoil, while noting Los Angeles did just as well as last year, but fell because of other cities progressing ahead of it.

Rounding out the top 10 is Portland, OR (4), Boston, MA (6), Washington, D.C. (8), Austin, TX (9), and Denver, CO (10).

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.
