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. The hydrogen is liquefied where electricity is cheap.

Bloomberg NEF forecasts falling battery prices enabling surge in wind and solar to 50% of global generation by 2050

Green Car Congress

The arrival of cheap battery storage will mean that it becomes increasingly possible to finesse the delivery of electricity from wind and solar, so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. trillion of that going to wind and solar and a further $1.5

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

The magnitude of these savings is ~5% to 15% higher in a system with 20% wind penetration compared to a system with no wind power, and the savings are 50–60% higher in a system that requires capacity expansion. Controlled charging can also take advantage of the high levels of wind generation that commonly occur at night in the US.

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF).

BNEF ups forecast for global investment in stationary energy storage, sees majority of capacity likely to be grid-scale

Green Car Congress

The report goes on to model the impact of this on a global electricity system increasingly penetrated by low-cost wind and solar. Falling wind, solar and battery costs mean wind and solar are set to make up almost 40% of world electricity in 2040, up from 7% today, according to BNEF.
