A new class of elastic energy converters is emerging, with the ability to capture energy from a variety of different motions. The National Renewable Energy Laboratory (NREL) is pushing to deploy them, first in a series of strange, bendy wave energy des… Continue reading Elastic, robotic generators open up strange new energy capture ideas
We’ve been banging on a bit about floating offshore wind turbines lately, but with good reason. Take a look at the US Energy Information Administration’s projected Levelized Cost of Energy (LCoE) figures for 2027, on page 9 of this report. Deep offshor… Continue reading 1-MW floating vertical axis wind turbine to be deployed off Norway
Stored hydrogen is often touted as the ultimate green energy solution, provided the hydrogen is produced from genuinely green power sources. But there are technical problems to be overcome before …read more Continue reading Renewable Hydrogen Sucked From Thinish Air
All the world’s greatest wind power resources are offshore – often a long way offshore, where the water’s so deep that it’s impractical to build typical fan-on-a-stick wind turbines with bases sunk deep into the sea floor. Floating wind, at this stage,… Continue reading T-Omega re-thinks floating offshore wind turbines for huge cost savings
CalWave has been working on its xWave clean power technology for many years now, and has announced the successful conclusion of an extended open-ocean test off the coast of San Diego, in which the device demonstrated over 99% system uptime.Continue Rea… Continue reading CalWave concludes 10-month test of its submerged wave energy generator
We interviewed the core team at Norway’s World Wide Wind (WWW) to learn more about its floating, tilting, contra-rotating, double turbine design, which it says can unlock unprecedented scale, power and density to radically lower the cost of offshore wi… Continue reading A deeper dive into World Wide Wind’s colossal, contra-rotating turbines
Reducing emissions from human activity requires a great deal of effort in many different sectors. When it comes to land transport, the idea is generally to eliminate vehicles powered by …read more Continue reading We Can’t Switch To Electric Cars Until We Get More Copper
Norway’s World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines (VAWTs) feature two sets of blades, tuned to contra-rotate – and they promise more than double the output of today’s biggest tur… Continue reading Contra-rotating floating turbines promise unprecedented scale and power
Sea Wave Energy Ltd (SWEL) has been working for more than a decade on a floating wave energy device it calls the Waveline Magnet. With several prototypes tested on- and off-shore, the company claims it delivers “ultra low cost,” with high output.Contin… Continue reading Wave-riding generators promise the cheapest clean energy ever
As wind power comes to play a larger role in the renewable energy mix, some scientists are casting their eye deeper into the future to address the issue of waste. We’ve seen some inventive ideas around how giant turbine blades might be saved from landf… Continue reading Bioplastic for wind turbine blades can be recycled into gummy bears
