Why is Hydroelectricity So Green, and Yet Unfashionable?

Cars That Think

I live in Manitoba , a province of Canada where all but a tiny fraction of electricity is generated from the potential energy of water. There is no end of gushing about China’s cheap solar panels—but when was the last time you saw a paean to hydroelectricity? Instead, that pure status is now reserved above all for wind and solar.

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). MMBtu) in 2050. Abatement cost with hydrogen at $1/kg (7.4/MMBtu).

Power-to-gas trial to inject hydrogen into Australia’s gas grid; A$5M award to AquaHydrex

Green Car Congress

On behalf of the Australian Government, ARENA has provided A$5 million (US$4 million) in funding to Wollongong-based AquaHydrex to develop commercially its new class of electrolyzer to produce cheap hydrogen from splitting water. When hydrogen burns, it produces only water vapor and no carbon dioxide.

Heating Buildings With Solar Energy Stored in Sand

The system uses electricity to heat air, which is then circulated through an exchanger that heats water and distributes it to multiple buildings in the city’s Hiedanranta district (Figure 2). The hot air then flows back out of the vessel into a heat exchanger, where it heats water that is then circulated through building heating systems.

Lux Research: cost of electrofuels remains far from viable

Green Car Congress

The cost of electrofuels—fuels produced by catalyst-based systems for light capture, water electrolysis, and catalytic conversion of carbon dioxide and hydrogen to liquid fuels—remains far away from viable, according to a new analysis by Lux Research. Production costs per barrel of oil equivalent. Source: Lux Research.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

As countries transition away from fossil fuels to green sources of energy like wind and solar, there will be natural lulls in energy production due to weather conditions. Kyoto Group Buildings are another big consumer of heat, accounting for almost half of total heat consumption, mostly for space and water heating.
