A hydrogen ramp-up is going to be expensive and asset-heavy. So, a whole-system analysis is needed to ensure its deployment is done cost-effectively today and meets long term goals. This is what all nations committing to hydrogen are struggling with. Kelley Travers at MIT describes their modelling, in collaboration with Shell, that looks at the optimisation of hydrogen deployment in grids where variable renewables (VREs) like wind and solar are … [Read more...]
Surging U.S. renewables on track to take 30% market share by 2026
While the U.S. Congress debates whether backing the transition is a winning strategy, the energy sector is clearly showing the nationâs direction of travel. Dennis Wamsted and Seth Feaster at IEEFA look at the impressive growth of the clean energy champions, wind and solar. Since 2019, wind and utility-scale solar generation has risen by 76 TWh â a 31% increase â while coal and gas has fallen by 1.6%. By 2026, wind and utility-scale solar will … [Read more...]
Redesigning UK electricity taxes to boost Heat Pump sales
In the UK, consumer prices for electricity are five times more expensive than for gas. It is a disincentive to adopt electric heat pumps. To make things harder, 23% of the electricity price comes from climate and social levies. Itâs just 2% for gas. No wonder the UK continues to install about 1.7 million gas boilers a year. Jan Rosenow and Richard Lowes at RAP call for changes that will incentivise customers to buy heat pumps while having a … [Read more...]
Methane Removal: an overlooked climate solution that could cut temperatures by 1°C?
If you think CO2 removal isnât getting enough attention, methane removal is getting virtually none. There are attempts to reduce methane emissions directly from fossil fuel production. But Rob Jordan at the Stanford Woods Institute for the Environment describes studies and models that conclude we should be looking at large and wide scale reduction and capture of methane. A 40% reduction in global methane emissions by 2050 could reduce peak … [Read more...]
Donât let high gas prices stop the EU ETS from doing its real job
The EU ETS carbon price reached a high of over âŹ60 per tonne in September. Some are arguing that its role in the current gas price crisis is a reason why it should be reined in. But Milan Elkerbout at CEPS Policy Insights explains that the EUA (European Union Allowance) has multiple purposes. It is an incentive to invest in low-carbon solutions such as renewables, efficiencies and new methods. The sooner we pass the cost hurdle of integrating … [Read more...]
Gas crunch: market and policy causes, and lessons learned
Andrei Belyi at the University of Eastern Finland says there are three main causes behind the huge rise in European gas prices. Everyone already understands that the reversal of the previous gas glut that gave us such low prices has been caused by a decline in European gas production, LNG imports and Russian gas deliveries. Added to that is the utilitiesâ reliance on spot contracts rather than termed contracts â great when prices were low â that … [Read more...]
Will Norwayâs new government consider phasing out oil and gas?
A Labour-led left coalition won the Norwegian elections in September. The Socialist Left Party looks keen to limit new oil and gas exploration and production. The dominant Labour Party and the Center party, much less so. Still, it could be the moment when Norway starts to put the climate above its oil and gas policy, explains Silje Lundberg at Oil Change International. Until now â left or right - itâs definitely been the other way around. The … [Read more...]
The U.S. now needs a Carbon Tax to transition from Gas to Renewables
Gas emissions must be halved (and coal eliminated) by 2030 to meet President Bidenâs goal of a carbon free power sector by 2035. The problem is that gas additions are half the price of new wind and solar installations. Though the clean energy champions are still getting cheaper, so are gas additions. Nikos Tsafos at the Center for Strategic and International Studies looks at the policy options over the next decade for the U.S. The stark fact is … [Read more...]
Germany 2021: coal generation is rising, but the switch to gas should continue
As news across Europe shows, a combination of factors is seeing coal powered electricity generation on the increase. Simon Göss at cr.hub, writing for Energy Brainpool, takes a close look at whatâs going on in Germany. The post-pandemic demand bounce-back, low generation from wind due to calm weather, and record high gas prices have made coal more competitive. Thatâs even with rising prices for CO2 and record high prices for coal (caused by … [Read more...]
How much Hydrogen will the German Gas Network have?
What will be the scale and design of Germanyâs hydrogen roll-out? Different scenarios are coming to wildly different conclusions. Simon Göss at cr.hub, writing for Energy Brainpool, looks at several, including the dena-TM95 scenario of the German transmission system operators for gas (FNB Gas) where gas consumption rises, and the NECP-KSP 87.5 scenario of the German Ministry for Economic Affairs where gas consumption falls. The possible hydrogen … [Read more...]
How to share the cost of an EU-wide Hydrogen network
The EUâs ambition is to make green hydrogen available throughout the region, and ramp up the transportation infrastructure as fast as possible to deliver it at a competitive price. But there are big disagreements between stakeholders over how and who should pay, explains Walter Boltz. The simplest solutions like focussing on hydrogen clusters will only deliver it to nearby customers. If only the customers pay it will make the hydrogen very … [Read more...]
Decommissioning coal, oil, gas: how funds can buy and retire the assets
Companies that want to retire their CO2-emitting assets (coal, oil, gas) can struggle to afford the cost of the decommissioning process. Brad Handler and Morgan Bazilian at the Payne Institute for Public Policy, writing for the World Economic Forum, explain how the creation of a new financial instrument, the 'carbon retirement portfolio' (CRP), could be a solution. In essence, itâs simple. Investors create a fund that buys the asset and takes the … [Read more...]
Record global power sector emissions by 2022, because Renewables arenât growing fast enough
The IEA is forecasting that renewables will cover only half the projected increase in global electricity demand in 2021 and 2022. Despite renewablesâ impressive growth, coal and gas will be needed to cover the rest. That means emissions will rise to record levels. That will be the reverse of the IEAâs (and many othersâ) âRoadmap to Net Zero by 2050â pathway, where three-quarters of global emissions reductions between 2020 and 2025 come from the … [Read more...]
Comparing four Carbon Removal scenarios (IPCC, IEA, McKinsey, NGFS) and policy implications
Most net-zero scenarios include carbon removal as a major component. Simon Göss and Hendrik Schuldt at cr.hub review five major scenarios from the IPCC, IEA, ETC, McKinsey, and the Network for Greening the Financial System (NGFS). They start by making the very important distinction between carbon capture and negative emissions: capturing carbon from, say, a gas plant does not deliver negative emissions, it just prevents new emissions. This … [Read more...]
UK: exposing the gap between ambitious climate laws and actual policies
Like many nations, the UK has big gaps between what is actually needed to reach net zero by 2050, what targets and ambitions have actually passed into law, and what policies are actually in place to comply with those laws. The UKâs climate watchdog, the Climate Change Committee (CCC), has issued two reports that measure the UKâs performance and makes recommendations, summarised here by Josh Gabbatiss at Carbon Brief. The first report focuses on … [Read more...]
