Techno-economic analysis of ammonia decomposition for large-scale hydrogen production

In the transition towards a renewable energy-powered industrial sector in the Netherlands, hydrogen plays a pivotal role. The anticipated increase in hydrogen demand by 2030 is projected to exceed the anticipated capacity of domestic green hydrogen production, hindered by the high costs and fluctuations of local renewable electricity generation....

Dynamic behavior of a flexible small­scale ammonia synthesis process

Due to climate change, the growth in renewable energy is still accelerating and reaching new records each year. Not everything can be electrified, hence, the production of green hydrogen as an energy vector is gaining momentum. However, lowest cost hydrogen will not always be produced at the demand centres, necessitating transport of hydrogen...

Costs competitive large-scale green hydrogen production in North-Africa in 2030: How can a system that produces green hydrogen and ammonia be optimized to minimize the levelized cost and will this system be able to compete with fossil fuel based production in 2030?

The European Green Deal states that it wants to develop 40 GW of electrolyzer capacity by 2030 in North Africa to combat climate change. Using PV power as the primary energy source, a system is designed that can produce green hydrogen and ammonia to investigate how the location and the capacity of the components can be optimized to produce at...

Optimisation-based system designs for deep offshore wind farms including power to gas technologies

A large deployment of energy storage solutions will be required by the stochastic and non-controllable nature of most renewable energy sources when planning for higher penetration of renewable electricity into the energy mix. Various solutions have been suggested for dealing with medium- and long-term energy storage. Hydrogen and ammonia are...

The potential of green ammonia production to reduce renewable power curtailment and encourage the energy transition in China

The pursuing of inter-regional power transmission to address renewable power curtailment in China has resulted in disappointing gains. This paper evaluates the case of local green ammonia production to address this issue. An improved optimization-based simulation model is applied to simulate lifetime green manufacturing, and the impacts of main...

Exploring supply chain design and expansion planning of China's green ammonia production with an optimization-based simulation approach

Green ammonia production as an important application for propelling the upcoming hydrogen economy has not been paid much attention by China, the world's largest ammonia producer. As a result, related studies are limited. This paper explores potential supply chain design and planning strategies of green ammonia production in the next decade of...

Shipping Renewable Hydrogen Carriers: A study on the impact of shipping renewable hydrogen carriers and using those as a fuel on, the ship design, the different powertrain configurations, and the cost of transported hydrogen

Hydrogen enables renewable energy storage, and hydrogen carriers can allow easier transportation. This research was initiated to get more insight into transporting renewable hydrogen carriers (RHCs) by ship, which is one of the transportation options. The research was conducted in three steps. First, a system description with a literature study...

A Techno-Economic Evaluation of Green Ammonia

Up until now, ammonia has primarily served the fertilizer and chemical industry with limited regards to carbon emissions. The hydrogen within the ammonia molecule is commonly produced using fossil fuels; this process accounts for 1,2 % of the global CO2 emissions. Rather than using fossils fuels, electrolysis with renewable energy could be used...
