In a normal internal combustion (IC) engine, the crankshaft (+ rods, wristpins & pistons) is the mechanism which captures a portion of the energy released by combustion and converts it into motion. WaveTech Engines have re-thought the normal IC design and created a more "wave-like" motion for pistons vs the tradition up and down rotation. Under computational fluid dynamic (CFD) analysis, this design indicates 40% less fuel is required for the same or more useable power. In other words greater energy productivity, with added benefits of lower fuel costs and lower emissions. https://www.wavetechengines.com/index.html

Geothermal power plants are typically located near easily accessible, and sufficiently hot hydrothermal reservoirs. This limits their potential. But Canadian Eavor Technologies Inc has designed a closed-loop conduction system which uses the Earth's natural heat to warm a benign, constantly circulating fluid. In short, its like a radiator, just 3 - 5 kilometres underground. The cooler water entering the loop pushes the hot water up to the surface, the heat is captured to deliver constant, predictable, emission-free, base-load electricity and then simply goes back into the loop as cooler water. https://www.upstreamonline.com/energy-transition/bp-and-chevron-become-part-owners-of-de

More than $226 billion of Australian assets are exposed to coastal erosion which is only getting worse with climate change. A collaboration of researchers, industry and the Mid-West Ports Authority are exploring the use of wave energy converters to absorb and harness the damaging waves that hammer Australia’s vulnerable coastlines during severe weather events. They aim for better management of coastal erosion, generation of renewable energy for guilt-free power and recovery of costs, and perhaps even the support of stronger ecological values in the local area. https://www.swinburne.edu.au/news/2022/02/producing-electricity-while-protecting-vulnerable-coastlines/

The UK Government recently announced funding for 11 Floating Off-shore Wind (FOW) projects - each project showcasing and trialling something reasonably unique in the sector. One of these projects is a hybrid wind and wave project by Marine Power Systems. The company is proposing to demonstrate a 2MW scale platform that also simultaneously harnesses 0.5MW of wave energy. Being able to cost-effectively combine the two provides reliability benefits, as well as obvious cost benefits.

It is both.  Denmark has the highest penetration of wind energy in the world. It is also a country with a love of cycling. It is estimated that 9 out of every 10 Danes own a bike. So it is really no wonder they are looking at ways to combine the two! This image shows a re-purposed wind turbine as a bike shed. 

Such a scheme would provide an internationally recognised system that would differentiate between hydrogen based on carbon intensi
