Nuclear plants have high up-front costs, complex processes occurring all the way down to the molecular level throughout their decades-long lifetimes, and strict safety criteria. Modelling all the parameters and predicting the outcomes has traditionally begun with theory and observation followed by simulations, the results of which are fed back into the next round of theories, and repeated until those results look valid. The quality of the … [Read more...]
The value of PPAs during economic turmoil
IEEFA says that the global economic slump being caused by the coronavirus pandemic can show how Power Purchase Agreements (PPAs) protect you against uncertainty. PPAs are long term contracts and prices agreed with energy suppliers. Renewable energy PPAs are one of the best ways big customers in the private sector can support the transition, guaranteeing suppliers income over the long term. Particularly for electricity-intensive sectors, renewable … [Read more...]
Biogas and Biomethane’s untapped potential across the world
The IEA’s World Energy Outlooks have no doubt that electrification alone cannot meet our climate goals. That’s why natural gas continues to play a major role. But biogas and biomethane have the potential to replace 20% of that gas, says the IEA’s special report “Outlook for biogas and biomethane: Prospects for organic growth”. At present only a fraction of that is being utilised. Here the IEA summarises their comprehensive report. Costs are the … [Read more...]
Germany’s drive to decarbonise its prized heavy industry: an overview
Sören Amelang at Clean Energy Wire runs through their collection of factsheets, analyses, reports and interviews that have tracked German industry’s attempts to grapple with decarbonisation. The very high energy intensity required by industries like steel, chemicals and cement makes a simple switch to clean electricity – short of a total redesign of processes – impossible. But Germany wants to maintain, even extend, its world leadership in … [Read more...]
Europe needs its own EV battery recycling industry
Europe needs its own battery recycling industry, and the EU’s European Battery Alliance should make it happen, says Raphaël Danino-Perraud writing for the IFRI Centre for Energy & Climate. For economic, strategic and environmental reasons, today’s overwhelming dependence on outsourcing – in this case to Asia - for battery manufacture and recycling needs to change. To start with, Asia provides over 90% of global car battery output, half coming … [Read more...]
China’s 2019 electricity generation reviewed as its next 5-year plan is drafted
Simon Göss breaks down the totals and additions for electricity generation in China. In 2019 the total reached 7,325 TWh (more than twice Europe’s) after adding 330 TWh (more than half Germany’s total). Of that 330 TWh, 120 TWh came from thermal (90%+ coal). But the numbers were dominated by renewables (hydro, wind, solar) which added almost 160 TWh. Though that’s the third year of declining renewables additions, wind and solar curtailment is … [Read more...]
Grid Battery tech on track. It now needs re-designed markets, monetisation
The rapid expansion of variable renewable electricity generation is making cost effective storage more urgent. Sure enough, in Europe several electricity storage projects are under construction and new ones are announced almost on a weekly basis. The battery technology seems to be on track, with estimates of $156/kWh in 2019 dropping to $61/kWh by 2030. But progress is hampered by the lack of a market that recognises and rewards the true value of … [Read more...]
Coronavirus bailouts should be explicit, not hidden by CO2 tax cuts. And nothing for Oil
Many industries will be pleading their case for a Coronavirus bailout. Severin Borenstein at the Energy Institute at Haas explains why the oil industry should not be one of them. Oil prices, already on the slide, are indeed sinking lower thanks to the pandemic. But decarbonisation should be sending them that way anyway. And the oil price has always be artificially high thanks to the OPEC cartel and weak or complicit “competition” from non-OPEC … [Read more...]
New EU Industrial Strategy focuses on emissions, but is it enough?
This month the European Commission released its new EU Industrial Strategy to set the direction of travel for the EU economy in the context of the European Green Deal. Energy-intensive industries - like steel, cement, aluminium, paper and chemicals - account for roughly 17% of EU emissions and have struggled to reduce them in recent years. But Johanna Lehne at E3G doubts the strategy is enough to meet the ambition of becoming the first … [Read more...]
Construction emissions: “mass wood” prototypes halve CO2, rapid modular deployment, 18 stories
Building and construction emissions account for two-thirds of the global total, with one tenth coming from the construction phase alone. David Chandler at MIT reviews their research, in collaboration with a range of specialist companies, into wooden buildings. Their construction emissions should be as low as half that of concrete or steel. The key is the development of large scale, cross-laminated “mass wood”. Factory built modules can be … [Read more...]
Coronavirus: economic stimulus plans open a door for clean energy
We’re facing an unexpected global economic slump thanks to the coronavirus sweeping across the world. In response, governments everywhere are tabling stimulus packages to get us through what is a temporary but severe drop in economic activity. That stimulus could be used, as it usually is, to get us back on the same path. But it should be used to steer us further and faster onto the new path of clean energy, says Fatih Birol, Executive Director … [Read more...]
How underground CCS works: low leakage risk, 2%
It’s not just the high upfront costs and the absence of a profitable business model that’s stalling the take-off of Carbon Capture and Storage (CCS). There are fears that CO2 stored underground will leak over the thousands of years it needs to be sequestered. The companies that put it there will be long gone. If you aren’t around to take the blame and pay the penalty, why bother doing it properly? Stephanie Flude at Oxford University and Juan … [Read more...]
EU Green Deal: meeting targets by lowering non-EU neighbour emissions too
The EU‘s Green Deal and its increasingly ambitious transition policies cannot be limited to its member states, writes Marc-Antoine Eyl-Mazzega at the IFRI Centre for Energy & Climate. For its emissions targets to be met in a meaningful way the EU needs to ensure its neighbours to the east and in North Africa follow. The danger is that carbon intensive industries simply shift to those neighbours, and their products get imported back in. … [Read more...]
Are national fossil fuel car bans compatible with EU laws, intra-trade, movement?
A growing number of EU nations are announcing laws to phase out the sale of new fossil fuel cars within the next 20 years. But are the proposed bans compatible with EU laws, or even workable given cross border trade and movement rights? If you are Dutch, why not buy your new petrol car in Belgium, then drive it back to the Netherlands? How do you enforce CO2 targets with foreign haulage fleets transiting through your nation? Eoin Bannon at … [Read more...]
Multi-energy “island” Microgrids can increase grid resilience
As the number of different technologies producing power and providing storage increases, the grid is getting complicated. The best way to make it resilient against outages is therefore changing. The traditional way is to shut down the failing plant, leaving the rest of the grid to cope as best as it can with the change in voltage and frequency. Xi Zhang at the Energy Futures Lab, Imperial College, describes the research looking at multi-energy … [Read more...]
