A hydrogen alternative

Renewable ammonia has the potential for rapid expansion. But technical and cost challenges stand in the way

Community cash to boost the transition

Local community groups are often seen as being against renewable energy sites or other projects to support the energy transition. But there is a rise in different ownership and funding models that includes local residents who do want to support the quest for a decarbonised economy

Will the UK’s permitting reforms speed up offshore wind deployment?

The UK's offshore sector has ambitious growth plans, but its permitting process could put its target at risk. Changes to the procedures could help accelerate deployment and provide a blueprint for other markets

Hydrogen sector targets production boost

Energy losses in the production process contribute to making hydrogen produced with renewable energy expensive. Companies and researchers are working to improve the efficiency of electrolyser technology and scale it up, bringing down the green hydrogen price tag at the same time

How to maximise energy efficiency investments

Sudden spikes in the cost of energy have pushed energy efficiency higher up the public and political agenda. Building renovations can be costly, but there could be ways of making energy efficiency itself more efficient

Decarbonising heat at city scale

Cities are taking the lead on the decarbonisation of district heating and cooling networks, with the use of heat pumps on the rise

Source new information from old data

Advocates of so-called digital twins—simulated computer modelling of technologies at work—see them as vital tools for managing the complexity of multi-level electricity systems and the digital control of energy-efficient buildings

Grid operators target next-generation weather forecasts

New technologies and faster computers are allowing improvements in weather forecasting. Understanding short-term weather patterns are helping grid operators cut costs and carbon emissions while keeping the lights on

Europe’s start-ups dig into battery recycling

Increasing the amount of recycled battery material available in Europe is encouraging new companies to examine different ways to maximise the extraction of the essential metals

Local energy auction trials made possible by digitalisation

CASE STUDY: The Cornwall Local Energy Market in the UK trialled algorithms to optimise auctions of power increase or load reduction offers while allowing simultaneous purchases of flexibility by different levels of grid operation

Turbocharge the process using digital tools

CASE STUDY: A new market service rolled out by the UK's electricity network operator in autumn 2020 invites fast-response injections of power or withdrawals of load from generators, electricity storage owners and consumers to help it contain frequency deviations that would otherwise destabilise the power system

Flexibility experiments work to cut the system costs of solar and wind

Network operators tasked with managing the steadily bigger swings in demand and supply that accompany greater uptake of solar and wind energy have had to choose between constraining clean generation, which adds to operating cost, or increasing grid capacity requiring capital expenditure. A less costly way is to buy system flexibility in a competitive but carefully coordinated process. Trials in areas of Britain challenged by grid constraints are producing encouraging results

Heavy industry to carbon light

Cement and steel manufacturing are two of the most carbon intensive industries in the world. Electrification can play a role in decarbonising both, though technology innovation is expensive and removing all emissions from the processes is a tall order

New finance model swaps coal for renewables

A finance mechanism that retires coal power stations and replaces them with new renewable energy capacity is gathering steam in the United States. But challenges remain in making this seemingly simple solution mainstream

Biodiversity must not be sacrificed to the energy transition

With the world facing an energy and a biodiversity emergency, realisation is growing that solutions need to be made compatible with sustainability in both areas
