Power to Fuel: Optimisation and characterisation of a small scale methanol synthesis reactor

In the effort against climate change the company ZEF has as its target to make methanol (CH3OH) out of atmospheric CO2; a process which can be seen as power-to-fuel and/or power-to-x. In light of the developmental cycle within ZEF a new reactor with an increased size and enhanced mass manufacturability is required. The...

Techno-Economic Evaluation of Refuse Derived Fuel Torrefaction

The last decade has seen an increase in the world wide energy demand, it was recorded as the highest spike encountered in the energy demand over a decade. On analyzing the main sources which were able to satisfy this overwhelming demand it was found that the majority was still from non-renewable sources or fossil fuels such as coal, oil and...

Exploratory Study on Nuclear-powered Trailing Suction Hopper Dredgers

Dredging is an energy-intensive operation and, due to the nature of the process, there are large and rapid fluctuations in the power requirement. With the signing of the Paris Agreement, implementation of IMO 2020 and expansion of ECAs, the external pressures for the reduction of different emissions(CO2, SO_x, PM, and/or NO_x...

An experimental and computational study of CO2 absorption in aqueous solutions of tetraethylenepentamine

Capturing CO2 directly from the atmosphere and subsequently using it to produce hydrocarbon fuels could help decrease mankind's reliance on fossil fuels and mitigate the risks of climate change. Zero Emission Fuels (ZEF) is developing a small-scale methanol plant, which utilizes atmospheric CO­2 and H2O vapor as feedstocks for renewable methanol...

Characterization of Transient behaviors and Operability study of a novel small scale Methanol Synthesis Reactor: Working on feed recycle by Natural Convection

The dwindling of natural resources, mainly fossil fuels, and the alarming increase in the global average temperatures, are the biggest concerns of the engineering and scientific community of 21st century. Studies have found that known reserves of oil and natural gas will last another 50 years. Coal will last another 110 years, which points...

Development And Characterization Of A Small Scale Methanol Synthesis Reactor Based On Natural Convection

Increasing renewable electricity production calls for innovative methods to store electricity as well as a desire for electrification of processes that currently rely on fossil fuels. Zero Emission Fuels is a company that is developing a system to convert carbon dioxide and water from the air into methanol, a liquid hydrocarbon fuel, using...
