Alan Ohnsman of Forbes writes about Plug Power, which is ramping up green hydrogen production. “Amazon plans to purchase over 10,000 tons of it a year in a deal worth up to $2.1 billion and Plug Power will also provide Walmart with enough fuel for 9,500 warehouse fuel cell forklifts. The company is also preparing to sell...
"'Unlike any type of wind turbine, Aeromine has two separate flow streams. This is maybe the only similarity with a Dyson-style fan because the physics is very different. The external airfoils facing the wind produce a low-pressure potential. The low-pressure potential drives an internal flow stream from a separate inlet through an internal propeller that extracts energy and then ejects the residual fluid into the free stream.'"
"The RHT is optimized for low head (from 2 meters to 20 meters) and doesn’t require fine fish screens. The design’s thick, slanted blades transport fish away from the leading edge into wide inter-blade regions and downstream to the outlet. The progressive slant of the blades from hub to tip also minimizes the likelihood of severe strike and eliminates the risk of entrapment between moving and stationary parts."
Whales are beautiful, amazing creatures that should be protected. Thankfully, through innovation and market demand, the shipping industry’s deadly impact on these animals may see an end—without forcing ships out of the water.
Julian Spector of Canary Media reports on energy storage funding through the Department of Energy. “In the habitually cautious utility space, track records count. No utility wants to bet its grid reliability on some new gadget only to see it fail to reach completion or fall apart at a crucial moment. And financiers hesitate to fund...
"NET Power’s transformational technology produces power while inherently capturing nearly all emissions with its patented oxy-fuel combustion and supercritical CO2 cycle. These plants produce clean, on-demand power at low cost and address critical issues of air quality and land use, virtually eliminating air emissions including nitrogen oxides (NOx), sulfur oxides (SOx), and carbon dioxide (CO2)."
"CE has been contracted by its U.S. development partner, 1PointFive, for the front-end planning and engineering of a one-megatonne DAC facility that is intended to be replicated into multi-million tonne deployments. The design is being adapted from the first large-scale, commercial facility to use CE’s DAC technology, which is already under construction in the Texas Permian Basin, and is anticipated to form the basis of accelerated large-scale deployments in the U.S."
