Offshore Methane Pyrolysis: A techno-economic analysis to assess the feasibility of offshore methane pyrolysis for the production of hydrogen

Methane pyrolysis is a technology that has the potential to greatly reduce the CO2 emissions of hydrogen production on a large scale. The process generates solid carbon instead of gaseous, thereby inhibiting emissions and has a relatively low process energy demand.<br/><br/>A three-step approach was taken to investigate the feasibility of...

Build and Experimental Characterization of a novel continuous Direct Air Capture system

The unprecedented rise in CO2 concentration in the atmosphere, and the accompanying rise in global temperature, has created the need for the development of environmentally friendly sources of energy. A very promising line of research focuses in the development of Carbon Capture and Utilisation (CCU) technologies; through which carbon-neutral...

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...

Dynamic operation of an Integrated Direct Air Capture and CO2 Compression System

CO2 concentration in the atmosphere has soared since the industrial era owing to the rapid and unabated increase in fossil fuel consumption globally. This has resulted in an increase in global average temperature by ≈ 1.1 C in this period; and has sparked the concern of climate disaster events across the globe. In order to tackle the issue of...

Ammonia Decarbonisation Pathways and Their Effects on Life Cycle Assessments: Integrating future ammonia scenarios into background data for prospective LCAs

Using the IEA Ammonia Roadmap aligned with the IMAGE electricity scenarios, an extensive database was produced allowing for prospective LCAs across three storylines from 2020 to 2050 (SSP2-Base, SSP2-RCP26, SSP2-RCP19). The scenarios correspond respectively to 3.9, 2.0, and 1.5°C of global warming in 2100 (vs. pre-industrial levels). Regionally,...

Characterization and Design of a Stripper for a Continuous Direct Air Capture System

Capturing CO2 directly from the air has gained wide attention as it is one of the possible solutions to mitigate the risks of climate change. Zero Emission Fuels (ZEF) is a start-up in Delft that develops a small-scale plant to produce methanol from sunlight and air only. CO2 and H2O are captured from the air by a direct air capture unit that...

Continuous Direct Air Capture, understanding mass transfer in reactive absorption of carbon dioxide: Experimenting and modelling a novel DAC absorption process

Increase in global energy demand has brought to a massive rise in greenhouse gases emissions. In particular, the continuously increasing atmospheric concentration of carbon dioxide is a major concern among the scientific community. This paved the way for an intense research of CO2 emissions mitigating technologies. Those ones including carbon...

Novel Technology for Hydrogen Separation from Natural Gas using Pressure Swing Adsorption

Australia has a high potential for production of renewable energy, such as wind and solar. Due to the stochastic operating conditions, excessively produced energy can be used to produce hydrogen by electrolysis to store the energy, known as power-to-gas. This hydrogen can be injected into the existing natural gas pipeline network, providing both...

Dynamic Electrochemical Promotion of Catalysis

Electrochemical Promotion of Catalysis (EPOC) is a method for enhancing a catalytic reaction by modifying the surface properties of the catalyst through the application of a small amount of current or interfacial potential. It can also be used to enhance the selectivity of heterogenous catalytic reactions. It was first discovered by M. Stoukides...

Direct Air Capture: Characterization and design of a novel absorption process

Rising concentration of CO2 in the atmosphere has become a significant concern, paving the way for worldwide research on mitigation techniques like carbon capture and storage (CCS) and carbon capture and utilization (CCU). Zero Emission Fuel (ZEF), an aspiring startup based in the Netherlands, aims to develop a micro plant that produces methanol...

Absorption of CO2 from the air using polyamines: Experiments, modelling and design

CO2 concentration in the atmosphere is increasing leading to global warming and thus, climate change. Moreover, current renewable technologies such as wind or solar energy only cover the electricity market. A big part of the global energy market is still based on fossil fuels and difficult to electrify. Hence, there is an urgent need to produce...
