Satellites: the spy who loved methane?
…contact us. Renewables slow-down: Could it be soooner? Another theme for 2020 is whether renewables growth will slow down, as heartland markets reach grid saturation. This was the precedent when…
Decarbonized power: how much wind and solar fit into the optimal grid?
…further 2-5x to accommodate just 3-15% more renewables. The lowest-cost, zero-carbon power grid, we find, comprises c25% renewables, c25% nuclear and c50% decarbonized gas, with an incentive price of 9c/kWh….
Wind power: decline rates?
…to 20. However, the data are highly variable, as shown by the examples plotted below. Volatility does matter for the costs of integrating renewables, the ultimate share of renewables and…
The laws of thermodynamics: what role in the energy transition?
…transition. Renewables are so good that they practically break the second law of thermodynamics. Hydrogen is so poor that it halves the pace of energy transition. Industrial efficiency technologies are…
Wind and solar: cost of grid interconnection?
…costs, or $3-10/kW-km, over a typical distance of 10-70 km. But the requirement to fund network upgrade costs can push grid connections to cost more than developing renewables projects themselves?!…
Hydrogen: overview and conclusions?
…have displaced 100MWH of high-carbon electricity directly (e.g., from coal). And all the more so, amidst painful energy shortages. (5) Backing up renewables? It is often argued that renewables will…
Global decarbonization: speeding up or slowing down?
…population growth, +1.4% pa rising incomes, -1.4% pa efficiency gains, -0.5% renewables, 0% nuclear, +0.2% ramping back coal due to underinvestment in gas. Depressingly, progress towards net zero slowed in…
Smooth operators: who benefits from volatile power grids?
Some industries can absorb low-cost electricity when renewables are over-generating and avoid high-cost electricity when they are under-generating. The net result can lower electricity costs by 2-3c/kWh and uplift ROCEs…
Renewable grids: solar, wind and grid-scale battery sizing?
…timeframe. Then model how big a battery is required to move the renewables to align with the timing of the power demand curve. This data-file works through the maths, for…
Power grids: when will wind and solar peak?
…solar heavy grids. This 12-page note draws conclusions from the statistical distribution of renewables’ generation across 100,000 x 5-minute grid intervals. $499.00 – Purchase Checkout Added to cart Wind and solar are…
