A study from the energy departments of Stanford University, from where Kara Glenwright writes, lays out a pathway for California to capture and store up to 60 Mt (million tonnes) of CO2 a year. 76 site locations have been identified where work could start immediately to store 20 Mt/yr profitably under the existing low carbon rules. But first a raft of clarifications on the laws is needed, showing that the success of CCS doesn’t just depend on the … [Read more...]
Which sectors need Hydrogen, which don’t: Transport, Heating, Electricity, Storage, Industry?
Which sectors are most suited to hydrogen, and which are not? For the answer, six academics from the UK and the Netherlands - Tom Baxter, Ernst Worrell, Hu Li, Petra de Jongh, Stephen Carr, and Valeska Ting – use their areas of expertise to neatly summarise hydrogen’s pros and cons in Road and Rail, Aviation, Heating, Electricity and Energy Storage, and Heavy Industry. Their general message seems clear: hydrogen is still very expensive, so it can … [Read more...]
5 charts show the rapid fall in costs of renewable energy
Plenty in the energy sector already know about the impressive declines in renewable energy costs since 2010, particularly solar (down 82%), concentrated solar (47%), onshore (39%) and offshore wind (29%). For those of you putting together presentations to people whose buy-in you need - citizens, public officials, investors, customers, etc. - these graphics should come in useful. It looks like a tipping point is being reached, says Douglas Broom … [Read more...]
The benefits of Peer-To-Peer Electricity Trading for communities and grid expansion
The adoption of peer-to-peer (P2P) electricity trading will turn individual consumers from passive to active managers of their networks. Such a marketplace can relieve constraints on the growing system and offer an alternative to costly grid reinforcements. Arina Anisie and Francisco Boshell at IRENA run through the benefits, including investment costs, bills, resilience, congestion, mini-grids, energy access, and more. They note that very few … [Read more...]
Rooftop Solar: economies of scale can challenge the centralised grid
One of our recent articles explained how rooftop solar PV is more expensive that a centralised supply, and that the transmission and distribution cost savings of the rooftop system, on their own, do not make up for this cost difference. Here, Javier López Prol at the Wegener Center for Climate and Global Change, University of Graz, responds to those challenges. First, the economies of scale of distributed rooftop solar are yet to be realised. … [Read more...]
Rural America needs investment, jobs. $82bn/yr of Wind and Solar can deliver it
The build out of wind and solar in the U.S. – to rise from 165GW today to over 500GW in 2035 – will overwhelmingly happen in the open spaces of rural America, explains Kevin Brehm at RMI. It should result in a major boost to stagnating communities. The $82bn/year of clean energy investment will take second spot to the current three big rural spends: highways ($90bn), water utilities ($57bn) and mass transit ($45bn). By 2030 rural clean energy … [Read more...]
Are 1.5°C scenarios supplanting “Business As Usual” as the new benchmark?
The world energy outlooks published annually by the IEA, BP and DNV GL look very different this year. 1.5°C scenarios are being taken much more seriously. Could it be because of the trauma of Covid-19, or the extraordinary – though still insufficient – success of renewables coupled with the rising ambition of climate-aware governments and their policies? Either way, they are helping to shift the debate away from the mainstream “business as usual” … [Read more...]
Decarbonising end-use sectors: buildings, transport, industry. Which strategies are best?
The rapid pace of change in the energy sector is a positive sign for the transition. But the disruption it causes creates another big problem. It makes it harder to predict what will happen next. That makes strategies and pathways harder to design, and increases the risk of stranded assets. To try to come to grips with that future, Sean Ratka, Paul Durrant and Francisco Boshell summarise the findings of IRENA's 4-day “Innovation Week” held last … [Read more...]
U.S. Nuclear: change the laws that constrain foreign and domestic investment
Today, Russia and China dominate global nuclear exports and new additions while the U.S. experiences budget overruns and cancellations. Once at the forefront, the U.S. should regain its leadership of nuclear power, argue Matt Bowen, Jennifer Gordon and Jackie Kempfer at the Atlantic Council. To recover its position it first needs to change the laws and policies that constrain its ability to cooperate with allies on nuclear matters, invest in … [Read more...]
Renewables shares outperformed fossil fuels over 10 years. Have investors noticed?
Shares in listed renewables firms are outperforming their fossil fuel equivalents, both in terms of returns and volatility. But although investment is rising, they’re still not getting enough to meet our 2050 targets, says the IEA. Why? In this article summarising the first of a series of reports they look at the 5 and 10 year record of the two verticals. In all the three territories analysed – the U.S., the U.K., and Germany/France - renewables … [Read more...]
Zero U.S. power sector emissions by 2035, says Biden. How?
Joe Biden, the Democratic presidential hopeful, wants to reduce U.S. power sector emissions to zero by 2035. That’s more ambitious than Obama, and more than what Biden promised when campaigning to be the Democrat’s candidate. His emphasis has been on the jobs and investment a green economy will create – language that has more voter appeal than reversing emissions. Meredith Fowlie at UC Berkeley’s Energy Institute at Haas reviews the promises … [Read more...]
U.S.: Counting Renewables jobs and projects under threat, what can be done and why
All sectors across all economies are trying to add up their potential job losses and projects in jeopardy, then telling their governments to prioritise them for support. Mike Jacobs at the Union of Concerned Scientists looks at renewables in the U.S. He quotes news reports that over 100,000 workers in this fast-growing industry filed for unemployment in March 2020. On top of that, the already planned expiry and phase-down of certain targeted … [Read more...]
Designing the Covid-19 stimulus: what the 2008 crisis can teach us
Policy makers around the world are hearing a lot of advice on how to design their stimulus packages. This comes from the IEA where Fatih Birol lays out five fundamental lessons we can learn from the stimulus packages that came out of the 2008 global financial crisis. His main headings are: Build on what you already have – and think big (e.g. feed-in tariffs, production tax credits); Choose technologies that are ready for the big time (e.g. wind, … [Read more...]
IEA: Three ways governments can keep Renewables growth on track
Before the coronavirus pandemic, 2020 was set to be another record year for renewables installations. That is now looking very unlikely. Heymi Bahar at the IEA identifies three main challenges facing the growth of renewables due to the global economic consequences of the pandemic: Supply chain disruptions, anywhere, will surely lead to delays in completing projects everywhere; Compounding those delays, major renewables incentives expire at the … [Read more...]
Will China build more Coal to stimulate the economy?
Could China ramp up coal generation – of the order of hundreds of GW by 2030 - as part of its efforts to stimulate its economy and recover from the coronavirus slump? The thinking is that building a coal plant converts faster into economic growth than the equivalent spent on renewables. In the previous decade, building coal plants was an effective part of China’s economic growth plan that secured its place as the world’s second largest economy. … [Read more...]
