CH4 context: the largest methane leaks of all time?
…out all Russian gas by 2030, as it becomes ‘first in the firing line’ to be displaced by renewables. An observation from compiling the data-set is that many methane-leaking events…
How does methane increase global temperature?
…world’s lowest cost roadmap to net zero. The reason is that while we are ramping renewables by over 5x, this is still not enough to offset all demand for fossil…
Energy shortage: fear in a handful of dust?
…transition. This is easier with an energy surplus. In the short term, building renewables and EVs consumes net energy (solar case study here). There are also materials bottlenecks. And CCS,…
Energy of rotation: angular momentum, inertia and flywheels?
…or raise the dragline again. There is more on flywheels, supercapacitors, batteries and smoothing out renewables volatility via the links in this sentence. Materials matter: high-strength low-weight maximizes energy storage?…
Cable installation vessels: costs and operating parameters?
…(such as HVDCs) cost $1-2M/km, and complex projects with erratic seabed terrain cost as much as $3-5M/km. Is it possible that attempts to accelerate offshore wind and renewables more broadly…
Nature based solutions: CO2 removals in 2022?
…step-change feels similar to the contrast between modern renewables and the small, inefficient wind and solar plants being constructed in the mid-2000s. We offer up some predictions on page 11….
Offshore wind: installation costs by vessel?
…wind and solar and the ramp-up of renewables in our roadmap to net zero. Please download the data-file to stress-test the numbers and see our estimates for the breakdown of…
Energy storage: top conclusions into batteries?
…for daily charging-discharging (model here). Conversely, there are many loads in the power grid that can shift their demand (e.g., to the times when grids are over-saturated with renewables). This…
Energy transition: the very hungry caterpillar?
…feels like the theme is also liable to gobble up whatever it encounters. We think the world will achieve an energy transition. The thermodynamics of renewables-electrification are simply astounding. And…
Gas turbines: operating parameters?
…are going to be a defining technology of the energy transition and a complement to renewables. The thermodynamics are explained here. The key point is that gas-fired power cycles are…
