It’s bad enough that 2018 net capacity additions did not exceed 2017’s after two decades of strong growth. It is far more troubling that nobody saw it coming, says the IEA, who have laid out the data and main cause: stop-go policies. 2018's 180 GW is only 60% of what needs to be added each year to meet climate goals. China, the EU, India and Japan all fell back. Only emerging economies, developing countries and the US (slightly) saw growth. … [Read more...]
50% Hydrogen for Europe: a manifesto
Electricity has well known limitations, mainly for bulk and long-range transport, industrial processes requiring high temperature heat, and the chemicals industry. To entirely replace fossil fuels we need hydrogen, say Frank Wouters and Prof. Dr. Ad van Wijk. It has an energy density comparable to hydrocarbons. There's more: Europe’s electric grid can’t cope with 100% electrification, yet hydrogen would use the existing gas pipe networks. The … [Read more...]
Russian – EU – Ukrainian gas talks: don’t believe the hype, it’s (almost) business as usual
The bilateral Russia Ukraine gas transit contract expires at the end of this year bringing the potentially conflicting interests of both parties and the EU into focus. The EU will be acting in the interest of those member states directly affected as well as having a role in avoiding tensions affecting its neighbour Ukraine. Cue much speculation from interested and neutral observers alike. Zuzanna Nowak, independent researcher and commentator, … [Read more...]
EXCLUSIVE INTERVIEW – GCCA’s Claude Lorea: “How can we provide the world with the concrete it needs in a sustainable way?”
Concrete is, after water, the most consumed resource on the planet and no other man-made material is more widely used. Without it, there are no buildings, bridges, dams or roads – no Sydney Opera House, no Hoover Dam or Golden Gate Bridge, no Pantheon in Rome. It is no surprise, then, that it has significant environmental impacts. More than 4bn tonnes of cement, the main ingredient of concrete, are produced every year leading to between 5 and 8% … [Read more...]
Transition funding: will Eastern Europe follow Lithuania and go green?
Lithuania is committing itself to renewable energy in a significant way, which could help shift the way other Eastern European countries define their interests in the energy sector. The EU is signalling its strong willingness to support countries that follow Lithuania’s lead, says political analyst Joe Mitton. Crucial decisions on the EU’s Modernisation Fund will be made in the coming months, allocating spending in the ten lower-income EU Member … [Read more...]
Hydrogen round-up: “fuel cells will replace diesel engines within 10 years”
As the focus moves from decarbonising the electricity sector to embrace transportation and heating, slowly but surely, hydrogen is starting to play a more important role. The gas has a number of advantages over electricity, including its flexibility and the fact that it can provide energy storage for long periods of time, unlike electricity. It can use the existing gas network if it is used for heating, and it is more appropriate than electricity … [Read more...]
EU oversight of foreign investment in energy projects lacking
At the 21st EU-China Summit on 9 April, both sides hailed a new era in the trade relationship. Increasingly confident of its domestic technological capabilities, China will soon no longer oblige foreign companies active in China to share their tech know-how. And a new Foreign Investment Law in China allows for greater inward investment to the country, but maintains restrictions and scrutiny mechanisms on 48 sectors of key strategic interest (the … [Read more...]
Electric Cars: only big subsidies lift market share off the 1.5% floor
You only need to compare the US to Norway to see how the main driver for EV sales is coming from government subsidies. Total Norwegian EV incentives cut the cost of running a typical 60 kWh battery pack from over $200/kWh to negative $336/kWh. US incentives bring it down to negative $23/kWh. The consequences are clear: generous Norway sees EVs take 31% of the market share in cars. In the US it’s 1.4%. That makes EVs a luxury item in the US (like … [Read more...]
36bn GWh: the “limitless” Geothermal from old UK coal mines
The Earth gets hotter by 2.5C to 3.5C with each 100m depth. It’s what makes geothermal energy possible, anywhere. In the UK geothermal could meet the nation’s heat demands for at least 100 years, say Jon Gluyas, Andrew Crossland and Charlotte Adams of the Durham Energy Institute. Properly managed it could last indefinitely. Given that heat does not travel well, geothermal must be developed locally. Fortunately, accessible heat lies beneath or … [Read more...]
2009 to 2017: solar, wind costs plummet, hydro steady, nuclear up
Between 2009 and 2017 prices dropped 76% for solar panels and 34% for wind turbines. Hydro and nuclear struggle to cut costs; as mature technologies, most of the efficiencies have already been squeezed out already. Also, they are difficult to productise and scale; dams (definitely) and nuclear plants (somewhat) are one-offs. In contrast, solar panels and wind turbines are far easier to productise and then mass produce. It’s why wind overtook … [Read more...]
There’s a limit to raising CO2 taxes. Re-focus on energy innovations to reverse emissions
Stop obsessing about raising CO2 taxes, says Severin Borenstein at the Energy Institute at Haas. It’s good, but not enough. Why? Textbook economics says if you tax something bad, innovators are incentivised and rewarded for coming up with something better. That’s true for cigarettes (vaping), plastic wrapping (recyclables, biodegradables), traffic (public transport). But there’s a limit with CO2 taxes, says the author. In developing countries … [Read more...]
Community Scale Solar plugs the gap between “rooftop” and utilities
Rooftop residential and utility solar exist at two ends of the scale. Is there a sweet spot between those two that can capture the advantages of small-scale (no transmission loss, grid resilience through distribution) and large (economies of scale, easy to invest in)? Yes, reports Laurie Stone of the Rocky Mountain Institute, and it’s being called Community-Scale Solar. More than a sweet spot, it can reach communities underserved by rooftop solar … [Read more...]
Leaked German govt report: emissions target will be missed despite on-target renewables
A leaked draft of Germany’s Energiewende Progress Report 2019, due to be released by the economy ministry in May or June, predicts the country will miss its targets for reducing energy use and greenhouse gas emissions by wide margins. This is despite the inevitable emissions reductions due to the 2009 recession and being on track for renewables. If no other measures are taken Germany will reduce emissions by 33% by 2020, falling short of the … [Read more...]
More nuclear means more waste disposal: the options, science, engineering
Public concern about nuclear power goes beyond an accident at a live plant. What do we do with the nuclear waste? If nuclear is to grow to become a major replacement for oil and gas the question must be answered. James Conca reviews the different methods that have been seriously considered: shooting it into space, burying it in deep sea trenches or under ice sheets, transmutation, or simply digging it even deeper underground. … [Read more...]
From rooftop solar to carbon divestment, California leads the transition
California doesn’t wait for Washington. As America’s most populous state by far, it is behaving like a separate nation when it comes to climate policies. Tim Buckley, Director of Energy Finance Studies at IEEFA Australasia, says it has become a global leader in renewable energy. Renewables provided 34% of its total energy needs in 2018, and the business community sees economic success in further progress. The author runs through the highlights, … [Read more...]
