The thermodynamics of hydrogen liquefaction are well known, writes Stephen B. Harrison, sbh4 consulting, but the equipment used in the liquefiers is still developing as the liquefiers scale up. Here, Harrison explores the current climate in...
Could the much-discussed ammonia economy ultimately overtake the hydrogen economy? Stephen B. Harrison ponders a pressing question in clean energies.
The route to decarbonisation and the energy transition has sometimes been described as defossilisation. Liquid fuels are incredibly useful energy vectors due to their high energy density and ease of handling. Gasoline, diesel, aviation kerosene...
Much has been said about CCUS – carbon capture, utilisation, and storage. The need to decarbonise is clear.
Making the transition from oxygen production and hydrogen purification to clean energy.
Creating green hydrogen, bio-CO2 and bio-LNG.
Heating is currently one of the major sources of greenhouse gas (GHG) emissions, accounting for 25% in the UK alone. In China, heating is mainly provided by coal-fired boilers, which not only act as major...
Medical oxygen concentrators produce gas in-situ. The concentrator is a certified medical device, and the oxygen purity is continuously measured. Medical oxygen generated by a hospital in this way for its own use requires no...
The natural gas price in mid-2020 was at an all-time low of $1.4/MMBtu. In the autumn of 2021, a four-fold increase to $6/MMBtu was observed as Asia built stocks in anticipation of a cold winter....
