Life Cycle Environmental Impacts and Socio‐Economic Implications of Tidal Electricity Generation and Storage in the UK

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
If tidal electricity generation and storage replaced natural gas and battery storage by 2050, it could reduce the climate change impact of UK grid electricity by 71%, saving up to 4.4 Mt CO2 eq./y. Most other environmental impacts would be reduced by up to 24%. However, high costs and low public acceptability hinder its deployment. ABSTRACT Tidal range

Toward the Utilization of Char from the Hydrothermal Liquefaction of Polyethylene Plastic Waste: Studies of the Adsorption of Rhodamine B in an Aqueous Environment

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
Hydrothermal liquefaction of waste polyethylene produces char that effectively removes rhodamine B from water. Nearly complete dye adsorption is achieved under optimum conditions, with adsorption following Langmuir isotherm and pseudo‐first‐order kinetics.

Subtask 3.3 - Feasibility of Direct Coal Liquefaction in the Modern Economic Climate [PDF]

, 2009
Coal liquefaction provides an alternative to petroleum for the production of liquid hydrocarbon-based fuels. There are two main processes to liquefy coal: direct coal liquefaction (DCL) and indirect coal liquefaction (ICL).

Preconversion processing of bituminous coals: New directions to improved direct catalytic coal liquefaction. [High temperature soaking coal in coal liquids prior to liquefaction] [PDF]

, 1992
Soaking coal in coal liquids at 300-400[degrees]C (high-tenperature soaking) has been studied for coal dissolution prior to liquefaction in the previous task. Two high-volatile bituminous coals, Illinois No. 6 and Pittsburgh No. 8, were examined in three different coal liquids.
