World Energy Outlook 2020: IEA responds to some difficult questions

by

The IEA has issued an FAQ to try to answer some persistent questions and criticisms about their annual World Energy Outlooks (WEO). How come the growth of solar and wind have been consistently underestimated? When is “peak oil” going to happen? Will the IEA’s Sustainable Development Scenario limit the global temperature rise to 1.5 °C this century? Is it realistic? Why has a “Net Zero Emissions by 2050” (NZE2050) pathway been added this year? Do … [Read more...]

Will Germany’s “EEG” energy law amendments make renewable targets harder to meet?

by

Germany’s Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz/EEG), now 20 years old, is under discussion as a new amendment is supposed to come into force on January 1st 2021. Simon Göss at Energy Brainpool takes a detailed look at the highlights, including the new and higher targets, the financial role of municipalities, clean electricity subsidies, and solar and wind tender volumes. He explains there has been serious criticism of the … [Read more...]

No more “offsetting”: Google commits to 24/7 locally sourced carbon-free electricity by 2030

by

By “offsetting” fossil electricity consumed at one data centre through buying green power from somewhere else, Google has been 100% renewable since 2017. But offsetting always has its flaws. In this case, 40% of Google’s actual power still comes from fossil fuels. Google’s new plan, to be 100% green 24/7 straight off the local grid, is designed to solve that. It will also send market signals to increase clean capacity locally, not just where you … [Read more...]

Grid scale Battery costs are declining faster than Wind and Solar

by

Gas as a transition fuel for grids may be around for a lot less time than we thought. We already know that large batteries, if they are cheap enough, can replace gas plants to provide peaking power to grids reliant on intermittent wind and solar. Bruce Robertson at IEEFA says the numbers are showing battery costs declining even more rapidly than wind and solar. Precisely because of that increased competitiveness Australia’s AGL Energy is starting … [Read more...]

Will Saudi Arabia build the world’s largest green hydrogen and ammonia plant?

by and

The Gulf is already a major producer and consumer of hydrogen, mainly for fertilisers and specialty chemicals. Like most hydrogen produced globally, it is the ‘grey’ kind made from hydrocarbons. But the region’s low renewable power costs and abundance of land give it the key components for the industrial scale production of green hydrogen. So in July, the Saudi model city of Neom (Neom means “new future”) and ACWA Power signed a joint venture … [Read more...]

Europe could have subsidy-free Offshore Wind by 2023

by , , and

A study has analysed offshore wind projects in 5 countries – the UK, Germany, Denmark, the Netherlands and Belgium – to show that wind farms due to be built after 2020 are converging towards a range of €50-70/MWh. It wasn’t long ago that such low prices were only predicted for 2050, say Iegor Riepin, Felix Müsgens (Brandenburg University of Technology), Malte Jansen and Iain Staffell (Imperial College London), writing for Carbon Brief. To make … [Read more...]

The new era of electricity needs modern ways to charge customers

by and

Today’s technologies – wind, solar, storage - have widely differing cost and operating characteristics to fossil fuels. So the way customers are made to cover those costs – assigning different rates to different customer classes – should change. Jim Lazar and Mark LeBel at RAP explain why and how, referencing their comprehensive manual “Electric Cost Allocation for a New Era”. They describe how the full range of technologies now establishing … [Read more...]

Three U.S. utilities to skip the gas “bridge”, move straight from coal to renewables

by

At the end of June, utilities in three U.S. states declared they are closing down coal plants and moving straight to renewables, without building new gas plants as a “bridge” fuel. For example, to replace lost coal capacity, Tucson Electric Power in Arizona will add 2,457MW of new wind and solar generation, backed up with 1,400MW of battery storage. Similar commitments are being made by other utilities in Colorado and Florida. New Mexico is … [Read more...]

BP’s world energy review: 2019 saw clean electricity match coal

by

Simon Evans at Carbon Brief summarises BP’s 69th edition of its influential annual statistical review of world energy, looking at 2019. Overall, total energy demand rose, though slower than usual. Renewables were the largest source of new energy, but were closely followed by oil and gas. Coal use dropped again, the fourth drop in six years, thanks to historic declines in the EU and the US. But continued growth in SE Asia, China and India leaves … [Read more...]

The PAC Scenario: net-zero by 2040 to meet Europe’s Paris goals

by and

The EU is not on track to meet its Paris Agreement obligations on emissions and limiting the global temperature rise to 1.5°C. CAN Europe and the European Environmental Bureau (EEB) present their Paris Agreement Compatible (PAC) scenario, designed to do just that. It’s been created through the careful analysis of contributions from more than 150 stakeholders including NGOs, scientists, industry and grid operators. Jörg Mühlenhoff at CAN Europe … [Read more...]

“Green” chemical plants that ramp up and down with wind, solar

by

One solution to variable renewables is to create customers that have no problem with ramping up and down production along with the power. In fact, when the wind and solar is producing too much power for the grid it can be bought very cheaply, making intermittent customers very happy. Jim Conca describes a new design for a Chlor-Alkali Chemical Plant that can “idle” without critical components of the plant degrading – the main reason for a plant … [Read more...]

Tipping Points reached for Solar, Wind, Batteries, EVs. What of the other Clean Energy techs?

by and

History shows a disruptive technology’s tipping point can be under 5% of market share, that’s all it takes. The number of horses in use peaked in the U.S. once car ownership reached 3%. Gas lighting in the UK peaked with electric lighting at just 2% of the market. Landline phones in the U.S. fell precipitously after mobiles captured 5% of the market. Ji Chen and Koben Calhoun at RMI argue the tipping point has already been passed for solar, wind, … [Read more...]

Energy Post panel discussion – Cross-Border Capacity [VIDEO]

by

Whilst renewable generation continues to grow, cross-border capacity fails to keep up. On May 19, 2020, Energy Post hosted a unique panel qualified to discuss the issue and shed some light on how we got here and what the options might be going forward. The discussion was moderated by Erik Rakhou - alternate member of the ACER board of appeal and consultant at Baringa. Representing the European Commission was Florian Ermacora and for independent, … [Read more...]

Negative electricity prices: lockdown’s demand slump exposes inflexibility of German power

by

The lockdown has unexpectedly allowed us to model certain aspects of the energy sector’s possible future. One is the oversupply of variable renewables into the grid. In Germany, a slump in demand plus an exceptionally sunny and windy few months sent wholesale electricity prices negative and to record lows. Fossil generators calculated that paying buyers to take electricity was cheaper than performing a shut-down re-start sequence, so they did … [Read more...]

Clean Energy threatened by lockdown of critical minerals supply

by and

Clean energy technologies depend on the reliable and growing supply of critical minerals and metals, far more so than the old fossil fuel world. An EV uses five times the quantity needed by a conventional car, and an onshore wind plant requires eight times that of a gas-fired plant of the same capacity. Hence, electric transport and grid storage are now the largest consumers of lithium and cobalt. Examples of rising consumption abound for other … [Read more...]
