Fast fashion and the climate challenge
Cheap, quick, and convenient, fast fashion has grown in popularity in recent years and contributed to the creation of an over-consumption culture when it comes to clothing. This may have a negative effect on wardrobe space, but the proliferation of fast fashion has had a much more harmful impact on the environment. Not only is the textile industry one of the highest polluting sectors, but it also uses a vast amount of water, adds microplastics to the ocean, and has produced a mountain of clothing waste that is either incinerated or ends up in landfill. But does the increase in consumer awareness and sustainable innovation mean there could be a more considerate way forward for the clothing industry?
What is white hydrogen and why haven’t we heard more about it?
The accidental discovery of natural white hydrogen in a well in Mali, West Africa has unlocked a whole new world of possibilities for this important energy source. Free from carbon emissions and ready-made with no need for costly electrolysis, white hydrogen could be a sustainable source of energy and contribute to the 200 million tonnes of low-carbon hydrogen per annum that the world will need to decarbonise by 2050. But it’s not a silver bullet solution – indeed, there are many problems that this burgeoning sector needs to address before it can play a significant role in the renewable energy industry.
CCUS: The state of play in the UK, European and US markets
Carbon capture, storage and utilisation (CCUS) has an important role to play in helping the world reach net zero by 2050. Harnessing innovative technology, CCUS works to remove carbon emissions from the atmosphere and either store them safely underground or repurposes them as a cleaner source of energy. Its importance has been recognised globally with the UK, European and US markets all committing substantial funds to its development, encouraging a burgeoning start-up scene and establishing new CCUS clusters that can help to decarbonise industry.
Cybersecurity challenges and solutions for large-scale green energy infrastructure
The green energy sector is notoriously vulnerable to cyber-attacks. Its reliance on electrification and a continual flow of data as well as its importance to infrastructure makes it a prime target for cybercriminals. However, despite the many challenges it faces, renewable energy providers can take a proactive approach to their cybersecurity to protect their operations and their customers, supported by robust government policy and targeted investment.
Common hurdles for renewable energy financing and how to overcome them
With a global investment target of around $4 trillion to reach by 2030, the renewable energy industry is in need of a significant injection of cash from both private and public investors. However, investing can be a risky business and renewable energy projects fuelling the clean energy transition must be carefully considered to avoid the challenges that have typically made markets understandably wary. From lengthy delays and increased costs to changeable government policies and public opinion, there are many hurdles impacting renewable energy financing. Happily, however, there are also several solutions that can help renewables fulfil both their environmental and financial potential.
Green manufacturing: Saving our planet while boosting business
As one of the sectors with the highest emissions and greatest impact on our everyday lives, manufacturing has an important role to play in the fight against climate change. The good news is that the green manufacturing movement has been gaining momentum in recent years, not only doing good for the planet but also providing economic benefits to businesses. There are several routes that firms can follow to make their operations more sustainable, from embracing renewables and finding ways to make energy more efficient to saving on governmental taxes and pursuing circularity.
Shining a spotlight on the new National Energy System Operator (NESO)
Since Labour came into power on 4th July, the new government has already made great strides in following through with its manifesto pledges and resetting the UK’s approach to the energy sector and climate change. Critics have been concerned that these ambitious plans aren’t backed by the investment or infrastructure needed to make them successful – and that’s where the new National Energy System Operator (NESO) could make all the difference.
Renewable energy progress in sport
While our attention is understandably often focused on the industries with the highest carbon footprints, its undeniable that other sectors can also play an influential role in helping us fight climate change. Sport is one sector that can take steps to improve its sustainable credentials and embrace renewable energy on a larger scale. It can also affect wider change by inspiring its fans to follow its lead. But is the industry ready to rise to the challenge and go for gold?
Deep dive: Redwood Materials
With global demand for lithium-ion batteries projected to increase by 90% in the coming years, existing supply chain issues and environmental concerns will only be exacerbated unless efforts are made to switch from a linear to a circular model. By adopting a recycle and reuse philosophy, the battery industry can become localised, more sustainable, and more resilient. One company, Redwood Materials, is leading the charge, providing a model for the industry to follow, and revolutionising the way the battery industry works in the US.
The carbon footprint of electrification: what we need to know
Electrification will play a vital role in the energy transition, but it’s not a perfect solution. Not only are there bottlenecks impacting the supply chain, but the carbon footprint associated with electrification is only set to grow as demand for electricity increases. Many renewable energy technologies, including solar PV, wind farms and electric vehicle batteries, rely on mined minerals in both their construction and operation. However, obtaining and processing these minerals has several negative consequences ranging from increased carbon emissions and water pollution to human rights and safety concerns.
Electrification’s pivotal role in the energy transition: Addressing supply chain hurdles for a greener future
While electrification is essential to facilitating a successful energy transition, blockages in the supply chain are at risk of derailing the race to net-zero when it matters most. As the demand for electricity grows, several issues have come to light, ranging from labour shortages and a scarcity of raw materials to restrictive policies that extend development times and leave projects stuck in limbo. If solutions are to be found in time, a collaborative and concerted approach is non-negotiable.
Nuclear in the UK – what is the endgame?
With experts in agreement that low-carbon sources must play a role in the energy transition, nuclear power has re-entered the conversation. A cost-effective, efficient, and reliable option, nuclear has many potential benefits, but is it a case of too little too late for the UK? The sector has been in steady decline since the 1970s, with successive governments failing to follow through on commitments to invest in and build new plants. However, innovations like Small Modular Reactors could offer a new way forward.
