The UK transition is often cited as a success story. Coal’s contribution has dropped from 40% to 6%. Wind, solar and hydroelectric now generates more electricity than nuclear. Demand for electricity has also fallen. The carbon intensity of Britain’s electricity has almost halved, from over 500g of CO₂ per kilowatt-hour in 2006 to under 270g in 2018. The National Grid now expects to be able to operate a zero-carbon electricity system by 2025. But … [Read more...]
Barriers to intermittent renewables and battery storage come tumbling down
The astonishing growth of the renewable energy sector shows little sign of slowing, as costs continue to plummet, along with the cost of energy storage, to remove many of the barriers to using intermittent renewable generating sources in a range of applications. Much of this is down to the fact that the cost of battery energy storage is one third lower than this time last year. … [Read more...]
China plans UHV transmission lines that span continents
China’s Global Energy Interconnection (GEI) project aims to create a worldwide network of UHV transmission lines that can deliver electricity between continents. If successful, generating electricity in the most remote areas – think deserts and the Arctic – becomes viable, as does China’s ability to sell electricity directly to Europe. First, two main technological challenges have to be overcome: energy loss along transmission lines spanning … [Read more...]
Renewable hydrogen “already cost competitive”, says new research
Jocelyn Timperley at Carbon Brief has interviewed the lead author, and the critics, of this new report titled “Economics of converting renewable power to hydrogen”. The research says renewable hydrogen is already proving competitive for niche, high-intensity users in Germany and Texas. Future technological improvements, combined with expected changes to subsidies and CCS requirements, can make it so for large-scale industrial users in the next 10 … [Read more...]
Investing in gas: the effect of carbon taxes, gas prices, and the growth of renewables
Schalk Cloete presents his latest article looking at what affects the profitability of an investment in a specific power sector. After reviewing onshore wind, nuclear and solar, he now looks at gas. His analysis of coal is to come. The major variables are increasing CO2 prices, and natural gas pricing. He adds that the growth of wind and solar should benefit load-following gas power plants: they are plugging the intermittency gap when electricity … [Read more...]
Wind build-out: convergence of process and permitting rules needed to promote certainty for investors
Two weeks ago, Energy Post reported on permitting and legal barriers to the development of onshore wind capacity in Germany. In this follow-up analysis, Mike Scott identifies similar obstacles in key regions as well as some clear success stories. To complete the picture, he spoke with WindEurope and Vattenvall to get their views on the way forward for the industry and investors across the EU. … [Read more...]
Energy as a service: light, heat, mobility, information
Large scale electricity generators, unconcerned with end-use, want to sell you more electricity, argues Walt Patterson of the Hoffmann Centre for Sustainable Resource Economy, based at Chatham House. But the arrival of small-scale, localised and micro-grid suppliers could see the electricity generation business turned on its head. It opens the door to the selling of the service – light, heat, refrigeration, motive power, information – rather than … [Read more...]
Will Toyota’s new battery design solve the looming shortage of vital metals for renewables?
We all know the important part played by lithium in battery manufacture. But there is a longer list of metals - including copper, cobalt and neodymium – that must ramp up supply for the continued rapid growth of EVs, solar, wind and other renewables technologies. EVs alone will increase the consumption of copper nine-fold by 2027. Cobalt prices already doubled in 2017. Neodymium use will rise by 700% in the next few decades to satisfy our need … [Read more...]
IEA: Battery storage races to keep up with solar and wind’s demand-matching challenges
Yesterday’s article from the IEA posed the question: will solar’s inherent intermittency slow its rise as a major power supply. For variable renewables like solar and wind to grow to over 50% of global capacity additions by 2040, storage technology must keep up with this pace. For this to happen, “flexibility” – the ability of the power system to quickly adapt to changes in power supply and demand – needs to grow by some 80% in the next decade … [Read more...]
EXCLUSIVE: Chinese government’s plan to meet the Paris goals
China is leading the energy transition as the world’s largest producer, exporter and installer of solar panels, wind turbines, batteries and electric vehicles. It has a clear lead too in renewable energy patents, ahead of the U.S. and twice that of the EU. But it is also still heavily dependent on coal, the air pollution in its cities is legendary, and the economy is expected to quadruple by 2050. Against this background, Kaare Sandholt, Chief … [Read more...]
Germany: wind installation growth beset by legal challenges
According to the German wind industry, new installations have ground to a halt due to a combination of red-tape holding up licences and because “almost every authorisation is sued”. A joint statement by the German Wind Energy Association (BWE) and VDMA Power Systems (the trade association for power systems) has called on the government to streamline licensing procedures and eliminate administrative barriers to new turbines, otherwise the … [Read more...]
Battery manufacture must take a global leap forward to ensure a sustainable and just transition
The global battery market is surging. By 2040 the global energy storage market is projected to attract $620 billion of investment. Over the past decade, the rechargeable lithium-ion battery market doubled on average every three years. To cope with this growth, we need the development of a sustainable and low-carbon value chain for batteries in order to contribute to the implementation of the 2015 Paris Climate Agreement, says Martin Brudermüller, … [Read more...]
Africa and renewables: the international partnerships bringing 300GW potential to life
Gaining access to energy is vital for Africa's people and national economies so tapping their vast potential for renewables is the obvious solution both for them and the climate. The challenge, as ever, is funding. To solve this, African nations are striking up international partnerships in a bid to unleash the full power of their phenomenal natural assets. … [Read more...]
UK nuclear plans are in tatters. But current incentives help gas, not wind and solar, step into the gap
The scrapping of plans for a new nuclear power station in Cumbria and the suspension of work on another in Anglesey have put the brakes on the UK’s nuclear future. But the government appears more keen to fill the gap with gas rather than renewables. David Toke of Aderdeen University criticises the current incentives and regulations and makes the case for wind and solar. … [Read more...]
Electric metering should break its link with power consumed and create it directly with the costs of delivery
In a world where electricity is generated from non-renewables (oil, gas, nuclear) our meters measure and charge us for electricity delivered, as if it was a fuel being consumed. Going forward, the cost should be measured against what is actually being consumed. In a renewables world – particularly 'run-of-the-river' hydro, wind and solar - that’s not the electricity. It’s the wear and tear on the infrastructure. Treating these types of renewable … [Read more...]
