There are more than 3m telecom towers globally, and powering them is a $100bn market. It's a particularly important growth sector in developing countries. They are already using mobiles to leapfrog the laying of costly landlines, but because they lack grids that stretch to remote communities they need to power towers that are off the grid. Dr Thomas Hillig says as solar and storage costs continue to drop they are replacing diesel gensets as the … [Read more...]
Virtual power plants: a story of market rules and smartgrids
Access to the grid-balancing market is competitive and carefully regulated. Green electricity from distributed and behind-the-meter renewable assets is already being traded on wholesale and balancing markets. The assets come in all shapes and sizes: roof-top solar, farmyard biofuel installations, EV and home battery systems, community energy projects, wind installations and heat pumps to name but a few. When they are pooled, by aggregators, they … [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...]
The race to phase-out coal: a nation-by-nation review
The global effort to phase out coal consumption is speeding up. However, a lot of necessary work is still to be done, both to align with the ambition of the Paris Agreement and to ensure a just transition for affected workers and citizens. Oliver Sartor at the IDDRI runs through the leading examples of coal's phase-out across the world, nation by nation, and warns that coal producing and consuming countries that do not adapt are in danger of … [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...]
Green New Deal can learn from Obama’s $90bn clean energy plan of 2009
The “Green New Deal” proposal is a 10-year plan to curb climate change by shifting the U.S. economy away from fossil fuels. Will it work? Yes (with caveats) if it’s anything like President Obama’s 2009 American Recovery and Reinvestment Act: it invested $90bn to promote clean energy as part of an economic stimulus plan to recover from the bank crash. That's the view of Joseph Aldy, Associate Professor of Public Policy at Harvard Kennedy School, … [Read more...]
WWF: A Just Transition needs a Just Facilitation
Katie Treadwell at the WWF European Policy Office says to successfully transition to a green and sustainable economy, the EU and its Member States must heed warning signs given by their constituents, such as at the Yellow Vests protest in France. They must ensure their approach to the transformation is ambitious, inclusive and facilitates a just and local transition. Just Transition policies are typically referred to in the context of coal … [Read more...]
Analysis: BP’s outlook for fossil fuels could be undermined by slowing energy demand
BP’s latest projections, released last week, once again concede that their previous reports have been overestimating fossil fuel consumption and underestimating renewables. Yet BP still predicts total energy demand will grow indefinitely thanks to overall global growth, and fossil fuels will always be needed. But Simon Evans at Carbon Brief shows how these projections contrast starkly with McKinsey’s, who find that the efficiency of renewables … [Read more...]
Can nuclear compete for a bigger role in the transition?
With plans to phase out coal-fired generators in most of Europe, nuclear is trying to compete with gas to become the most viable baseload power source to accompany renewables on the path to net-zero emissions. Both technologies have their advantages. Gas is competitively priced while nuclear generates power with almost no emissions. Right now, gas's cost advantage is evidently great enough to tip the balance. If nuclear advocates are to … [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...]
Corporate PPAs: renewables-rush as governments step back
Costs of developing clean energy capacity are falling and the industry is moving from being supported mainly by state subsidies to a more commercial footing where projects are supported by corporate backing, with EU, national or regional targets providing a foundation for the market. The US sportswear giant Nike has signed its first power purchase agreement (PPA) for renewable power in Europe, committing to buy 40MW of wind power from a 111MW … [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: Geothermal could represent a far bigger share of renewables
The IEA says geothermal energy could account for only 3.5% of annual global electricity production and 3.9% of energy for heat (excluding ground source heat pumps) by 2050. But is this down to short term thinking? Geothermal could make a much bigger contribution to renewables, provided it is put onto the fast track like wind and solar, says Alexander Richter, President of the International Geothermal Association. … [Read more...]
Electric buses: China leads through policy ambition but Europe could overtake
News comes of another renewables record for China. Shenzhen based manufacturer BYD has launched the world’s largest pure electric double decker bus fleet, to be delivered to the city of Xi’an. To illustrate China’s drive to dominate this market, they have already won the international tender to deliver 37 of a total of 68 new electric double decker buses to London, where the red double decker is an icon. That’s more than the remaining 31 that … [Read more...]
