AFC Energy: Power Tower & off road racing
Two updates from AFC Energy:
1. The “Power Tower”, a 10kW, ammonia-fueled, off-grid power was launched last month, with Keltbray and Acciona to deploy modular units on construction sites mid-year.
2. The launch of Extreme-H off road racing, with green methanol and ammonia likely to act as hydrogen carriers for the hydrogen-fueled racing championship.

Producing cheap, clean hydrogen: new updates
Three new updates this week:
1. A team at Durham University has shown that a massive scale-up of PEM electrolyser manufacturing capability can slash the capital costs of producing electrolyser units by up to 70%.
2. A team from the University of Campinas has proposed more focus on electrolysis of waste and seawater to produce hydrogen, avoiding direct competition between drinking water and hydrogen production.
3. A team from the Australian National University has demonstrated a new pathway forward for hydrogen production directly from sunlight by demonstrating a stable, efficient photocatalyst.

Ammonia combustion analysis: powertrains, turbines & power generation
This week we explore four updates in ammonia combustion R&D:
1. A team from the University of Cambridge has shown merchant vessels are the strongest candidates for conversion to run on ammonia powertrains, with cargo capacity losses of 4-9% able to be feasibly offset by operators.
2. Researchers at the University of Minnesota have successfully tested a thermochemical recuperation (TCR) reactor to improve the efficiency of a dual-fuel, diesel-ammonia compression ignition engine by minimising ammonia slip.
3. A global team led by Cardiff University researchers has revealed some of the inner workings of ammonia combustion in gas turbine flames.
4. A global team has produced a cradle-to-gate environmental assessment for ammonia production and ammonia-based electricity generation, suggesting that renewable and nuclear ammonia have a significant role to play in decarbonising the power sector.

Recovering ammonia fuel from wastewater & agricultural waste
This week we look at three new ammonia recovery projects:
1. A team from the Delft University of Technology has demonstrated that ammonia recovery via vacuum membrane stripping of a wastewater feed can be used to power a solid oxide fuel cell (SOFC).
2. In the UK, a new consortium including the Agriculture and Horticulture Development Board (AHDB) and the University of Leeds has received government funding to demonstrate a novel solution to harvest green ammonia from pig waste.
3. A team from the Ukrainian National University of Food Technology has proposed a new method of sourcing useable ammonia fuel from poultry waste via anaerobic digestion.
