IIASA study proposes solid air hydrogen liquefaction as efficient addition to hydrogen liquefaction supply chain

Green Car Congress

A new approach developed by researchers from the International Institute for Applied Systems Analysis (IIASA) in Austria and international colleagues proposes using solid air (nitrogen or oxygen) as a medium for recycling cooling energy across the hydrogen liquefaction supply chain. —Julian Hunt Resources Hunt, J.,

Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

Projected changes in summer mean usable capacity of power plants in the US and Europe for the SRES A2 emissions scenario for the 2040s (2031–2060) relative to the control period (1971–2000). A study published in Nature Climate Change suggests that thermoelectric power plants (i.e., Source: van Vliet et al. Click to enlarge.
