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...]
Competitive battery storage: InnoEnergy doubles prize to accelerate start-ups entry to market
Utilities and other investors are putting more funds than ever into a battery storage market worth an estimated $250 billion. Right on cue, European clean energy innovation engine InnoEnergy announced a global call for storage entrepreneurs. Their âŹ100,000 first prize meant applications from a diverse range of start-ups flooded in. But which of these should be fast-tracked into this competitive market? At a special event which highlighted a … [Read more...]
Small nations have big plans for nuclear energy
Dan Yurman looks at how small nations are trying to increase their nuclear supply. Romania has the US and China both pitching for business. The Czech Republic is still vague about giving electricity price guarantees, something that caused the collapse of a $25bn nuclear tender in 2014. Ukraine looks at Small Modular Reactors. The author starts with the Baltics â net importers of electricity â and Estoniaâs ambition to redress that balance using … [Read more...]
Global âsectoralâ treaties, legally binding corporate targets can turn around emissions rise
The United Nations Framework Convention on Climate Change started with a top-down legally binding Kyoto Protocol and ended up with a bottom-up âself-determinedâ voluntary Paris Agreement, says Chandra Bhushan. As a result, nobody has the tools to drive global collective action to combat climate change. The author says thatâs why emissions are at record levels. He recommends international âsectoralâ treaties to achieve real transition in energy, … [Read more...]
We need to trace the real fossil fuel users, not just the âend consumersâ
Climate-consciousness is rising among ordinary citizens. But most fossil fuels are consumed by large technological systems (electricity networks, urban transport systems, built environments, industrial and agricultural systems), not by individuals. Simon Pirani says we need to trace that consumption to its true source, and thereby put the pressure directly on them to transition. Itâs not simple: even the IEA admits it loses track of who is … [Read more...]
âStop trading renewable energy supply certificates, speed up the transitionâ
In the UK, REGOs certify that the power a consumer buys is renewable. As REGOs can be traded that means one supplier, sourcing 100% of their energy from renewables, and another simply buying enough REGOs to cover 100% of their output can both say they are 100% renewable. Is there a difference? Yes, says Thomas Harrison at supplier Good Energy. Trading REGOs takes the pressure off suppliers to use all their buying power to expand the supply of … [Read more...]
The rapid growth of solar integration into grids: learn from Germany
With the rapid electrification of Europeâs energy system, the network operators are facing a challenge. The integration of more and varied electricity generation is putting a strain on the growth of grids. Erik Rakhou and Chris Collins contrast the struggles the Netherlands is experiencing with the smoother ride navigated by Germany where in the 12 years to 2015 solar PV capacity rose around 100-fold from 0.44 GW to 39.7 GW. Greater investment, … [Read more...]
NECPs â Analysis: EU ideals coming up against political realities
The European Union is trying to maintain its leadership on climate change with its Clean Energy for All Europeans package, which aims to make the EU climate neutral by 2050. The mechanism for achieving this target is member statesâ National Energy and Climate Plans (NECPs). Mike Scott considers the plans, how Germany is moving towards an "Eastern European" energy policy and how the upcoming elections could dilute EU climate policy overall... … [Read more...]
German task force agreement on traffic emissions 1/3 off target
During what was billed as the decisive meeting, the German transport commission charged with proposing emissions cuts for the sector could only reach consensus on measures that will lower emissions by around two thirds of the necessary amount. Pro-climate activists, disappointed with the results, nevertheless welcomed the recommendation to look into the introduction of a CO2 price. Meanwhile emissions have actually increased. And VW, siding with … [Read more...]
New âGas for Climateâ scenarios: can green gas and hydrogen save gas pipelines?
Gas has a key role to play in decarbonising the energy sector. Until a comprehensive clean energy network can accommodate variable renewables using storage, baseload power will be needed. Natural gas is a lower carbon option than coal, so there is a strong case for it to be the first-choice bridging fuel towards a net-zero energy economy. However, exactly how much gas, what type of gas and how existing infrastructure can store energy in the form … [Read more...]
Why does coal survive? A detailed real-world cashflow analysis
Everyone knows coal plants are bad for the environment. So why do countries still use them? Coalâs attractiveness comes from the relatively low up front capital investment required to start generating energy. On top of that, the rapid rise of variable renewables (solar, wind) need something to rise with it to fill the generation gap when the sun doesnât shine and the wind doesnât blow. In his final instalment - after his similarly detailed … [Read more...]
U.S. buildings electrification hindered by ânewâ renovation policies that are already out of date
U.S. buildings renovation policies are not keeping up with technological progress and therefore risk slowing down electrification and the uptake of cleaner fuels, say Jessica Shipley and Donna Brutkoski of the think tank Regulatory Assistance Project (RAP). For example, there are policies and incentives that favour the installation of more energy efficient appliances, but ignore whether the appliance is greener. Put simply, policies need to … [Read more...]
Whatâs next for the geopolitics of energy transformation?
Januaryâs IRENA report âA New Worldâ has kick-started the debate on how the accelerating deployment of renewables will affect and alter the global distribution of political and economic power. Jan Frederik Braun and Daniel Scholten review its findings and build on the list of issues that must be faced. For example, although the IRENA report focuses on electrification the authors say power-to-gas is likely to play a major role, and we must face up … [Read more...]
East Mediterranean gas finds: EU energy bonanza or geopolitical headache?
Some of the worldâs largest natural gas reserves have been discovered off Cyprus. One of the questions being addressed at this year's CERA Week is, could these massive finds (totalling more than 70 trillion cubic feet!) be the answer to any perceived over-dependency on Russian gas imports to the EU? Maybe, maybe not. Geopolitical tussles could scupper the realisation of these much-needed resources for Europe. Whilst the potential is there, it may … [Read more...]
China plans UHV transmission lines that span continents
Chinaâs 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 â think deserts and the Arctic â becomes viable, as does Chinaâs ability to sell electricity directly to Europe. First, two main technological challenges have to be overcome: energy loss along transmission lines spanning … [Read more...]
