“IKEA Group investments into wind and solar energy generation contribute to the shift to a low carbon economy, and from a business perspective, help to secure our future as we become energy independent.” – Steve Howard, Chief Sustainability Officer, IKEA Group
87 of the world’s leading companies are now members of RE100.
Together they have a creating demand for around 107 Terawatt hours (TWh) of renewable electricity – around the same amount of power consumed by the United Arab Emirates or The Netherlands. Read More
Wattway, part of the France Colas constructions company, announced that four SolarRoad pilots will be built around the world in 2017.
Bloomberg December 4th:
(…) Colas SA, a French engineering firm, has designed rugged solar panels, capable of withstanding the weight of an 18-wheeler truck, that they’re now building into road surfaces. After nearly five years of research and laboratory tests, they’re constructing 100 outdoor test sites and plan to commercialize the technology in early 2018. (…/) Read More
In the body of the study it becomes clear that FCVs do not beat internal combustion engines (ICEs) by much in equivalent fuel economy, And they are not much better in greenhouse gas emissions either, particularly in the liquid hydrogen versions, because of the energy required to transport and compress the hydrogen.
Hydrogen fuel cell cars appear to be making a comeback. But is this real? The comparison in question includes discussion of:
the wider process behind producing hydrogen fuel
the production itself
the transportation of the fuel
The future is a bit cloudy for hydrogen fuel cells (HFC), as electric vehicles have developed quickly and taken significant market share. Read More
Tehachapi is nominally a wind energy-related project attached to the 4.5 GW Tehachapi Wind Resource Area, although in actual fact the plant was conceived as a two-year test bed for a wide range of potential grid applications. When it opened, in September 2014, it was credited with being the largest battery storage project in the North of the US, with 604,832 Li-ion cells housed in 10,872 modules.
Everyone knows California and New York do have behind-the-meter energy storage at a large scale. But there are some sleeper states where the economics already work.
During reel-out, the kite is flying figure-eight maneuvers at high speed (70 to 90 km/h). This creates a high traction force (3.1 kN at 7 m/s wind speed) which is converted into electricity by the drum and the connected 20 kW generator.
Kite Power by harnessing high altitude wind next step in Dutch Icon project ‘Afsluitdijk’.
Even NASA has started to work on airborne wind energy. This field is very new and has much room for innovation.
Flight testing with actual consistent measured power production is the next step.
