TfL plans purpose-built solar farms to power London Underground

Transport for London (TfL) is seeking partners to build a network of purpose-built solar farms that will be used to power the London Underground. The proposals could bring up to 64MW of electricity to the network, or approximately 5% of the electricity needed to run the entire network. The project is part of broader efforts to power all of TfL’s operations using 100% renewable energy by 2030. TfL said the projects will link directly to the London Underground, bypassing the National Grid entirely, while in the longer term private wire schemes could generate further savings. TfL is the largest single electricity consumer in London with a demand of approximately 1.6TWh per year – equivalent to the electricity consumed by around 420,000 homes. “By opening up new opportunities in the energy…

US shipping could be cost effectively decarbonised by 2035, study finds

A significant portion of the US shipping fleet could be electrified cost effectively by 2035, helping to make a dent in the carbon emissions from the sector, researchers have said. Shipping represents around 3% of total US greenhouse gas emissions from transportation. It is considered to be a sector that is hard to decarbonise as electrifying ships is considerably more challenging than electrifying cars from both a technical and a market perspective. A ship is also a much bigger capital investment than a car and has a lifespan of several decades. While better battery technology in recent years has meant electric vehicles with longer ranges, ships are vastly heavier than cars and can travel very long distances between ports. These heavy weights and long distances have led to concerns that…

What the budget to ‘restore economic stability’ means for engineering and technology

Chancellor Rachel Reeves has delivered Labour’s first budget since the party took to power in July 2024. Rachel Reeves stood up in the House of Commons to deliver the budget, marking the first time a Labour government has announced a budget in 14 years and the first time a female chancellor has done so in the 800-year history of the role. Since she stepped into the job in July, Reeves has made it clear that she has inherited a “£22bn black hole in public finances” from the previous Conservative government. In the House of Commons she started off the over 80 minute-long budget speech by saying: “The only way to drive economic growth is to invest, invest, invest. To deliver that investment we must restore economic stability and turn the page on the last 14 years.” She stressed that the…

Rolls-Royce SMR partners with Czech power firm to bring small modular reactors to Europe

Rolls-Royce SMR has signed a deal with Czech power company ČEZ Group to expand production on its small modular reactors (SMRs). SMRs are easier to scale and more affordable than building larger nuclear power plants. The entirely factory-built facilities can be transported as modules and assembled on-site, radically reducing construction activity and making SMRs a commodifiable product. Another advantage is that SMRs can meet smaller, localised power demands, be scaled up for larger demand or used to complement renewable energy sources. As part of the deal, ČEZ will deploy up to 3GW of electricity in the Czech Republic, using power plants developed by Rolls-Royce SMR. Tufan Erginbilgiç, CEO of Rolls-Royce, said: “We have a shared vision, and ČEZ further strengthens our ability to build…

UK government invests £68m to transform brownfield sites into land for new homes

The UK government is to provide councils across the UK with a multi-million-pound funding boost to help unlock disused brownfield sites and get the “country building again”. When Labour came to power in July, it pledged to build 1.5 million new homes in the form of new towns and ‘Georgian-style’ houses. To do this, the government said it would reform compulsory purchase compensation rules, allowing more sites to be unlocked for affordable housing development, as well as relaxations over building in the grey belt – defined as brownfield sites and poor-quality areas in the green belt. The government has now announced it is committing to this pledge with an investment of £68m that will be divided among 54 councils across the UK to transform brownfield sites into land suitable for building…

Nasa identifies nine landing sites for its first crewed Moon mission in over 50 years

Nasa has identified nine unexplored sites for the first crewed Moon landing in half a century that it says could hold vital resources, including water. For its Artemis III mission, Nasa has proposed landing regions that warrant further scientific investigation, all located near the lunar south pole. The Artemis programme was formally established in 2017 and launched its first uncrewed mission in November 2022 using the long-delayed Space Launch System rocket. Artemis II was originally planned to take place this year and would have been the first scheduled crewed mission since 1972, with four astronauts performing a flyby of the Moon before returning to Earth. This would have been followed by a crewed landing on the Moon for Artemis III in 2025. Unfortunately, the US Government Accountability…

Generative AI technology is creating a growing e-waste problem, study warns

The increasing popularity of generative AI technology could worsen the ongoing e-waste problem by creating an additional 5 million metric tons of e-waste in total by 2030, researchers have said. Generative AI works by using complex algorithms to create new content – such as text, images, music or video – that mimics or extends patterns found in existing data. But the technology is highly dependent on rapid improvements in hardware infrastructure and chipmaking that incentivises firms to undertake rapid hardware upgrades. As well as the need to simply increase the computational power of the machines used to train the AI models, these models are also very power hungry, which comes at great expense. Moving to more energy efficient hardware can help to save energy costs in the long run. A…

Chancellor Rachel Reeves urged not to cut funds to Sellafield amid safety concerns

Budget cuts at Sellafield increases the risk of “devastating consequences” at the world’s biggest plutonium stockpile, the GMB union has warned. In a letter written to Chancellor Rachel Reeves ahead of the Budget next week, the GMB warns of the “risks posed by reducing funding for such a complex and hazardous site”. Sellafield, on the coast of Cumbria, is the UK’s most complex and challenging nuclear site. The scale of the decommissioning operation is vast and will last until 2039. Just last week a new National Audit Office report found that progress on the site is slow and is “not yet achieving value for money.” The site is owned by the Nuclear Decommissioning Authority (NDA), which is an executive non-departmental body sponsored by the Department of Energy Security and Net Zero. …

Gas cookers in European homes linked to 40,000 premature deaths a year, report finds

Exposure to nitrogen dioxide (NO2) from burning gas indoors is linked to 39,959 premature deaths in the EU and UK each year, according to researchers at Spain’s University Jaume I. The figures are revealed in a study estimating the health impact and economic cost associated with exposure to NO2, a toxic gas emitted by gas cookers. Around a third of European households use gas cookers at home. When in use, these indoor cookers emit NO2, as well as other pollutants, into the household. The study also estimates that exposure to NO2 is linked to hundreds of thousands of paediatric asthma cases each year, with Italy, Poland, Romania, France and the UK among the worst-hit countries. To create a map of NO2 concentration in European homes, the researchers combined existing real-world pollution…

UK must cut 81% of carbon emissions by 2035, climate scientists say

Climate experts have said the government needs to cut the UK’s greenhouse gas emissions by 81% by 2035 if net zero commitments are going to be met. The reduction, which is relative to the UK’s emissions from 1990, will require “rapid but achievable action”, the Climate Change Committee (CCC) said. The independent body is responsible for advising the government on policies that it needs to implement in order to tackle climate change. In August, energy minister Ed Miliband asked the CCC to provide advice on meeting the UK’s 2035 nationally determined contribution. The UK has already cut its emissions by more than 50% since 1990, but the CCC said that “rapid reductions” in fossil fuel dependence were the best way to enhance UK’s energy security, while green investment would also help to support…

Royal Mail urged not to scrap its freight trains to cut emissions and road congestion

The government has been urged to reduce track access charges and electricity costs for freight trains in a bid to get Royal Mail to reverse its decision to stop transporting mail by train. In July, Royal Mail announced it would stop using its dedicated fleet of mail and parcel carrying trains in October due to the cost of running electric trains and because its purpose-built train fleet would require expensive investment to continue operations. To make up the shortfall, Royal Mail said it would switch to delivering mail and parcels by road and has been investing in “green” trucks that use hydrotreated vegetable oil instead of diesel, as well as battery delivery vans. The firm has been running trains to transport post since 1830. The Campaign for Better Transport (CBT) has delivered a…

Designing the ultimate theme park thrill ride

The theme park business is a roller coaster, using new technologies to build rides that are faster, higher, longer – but also more engaging. Qiddiya Entertainment City lies roughly 45km from Riyadh and is a leading component of Vision 2030, Crown Prince Mohammed bin Salman’s plan to establish Saudi Arabia as a global economic and cultural leader. One objective is to increase tourism – and roller coasters are well on the way to achieving that goal. Within Qiddiya’s Six Flags theme park, construction of Falcon’s Flight is well advanced. When completed it will be the fastest, tallest and longest coaster in the world. It will take a 600ft drop off a cliff edge and then ascend a 640ft ‘airtime’ tower (‘airtime’ because riders experience weightlessness or even a more intense pushing out of…

$100m settlement agreed by shipowner in US lawsuit over Baltimore bridge collapse

The US justice department has said that Grace Ocean and Synergy Marine, the Singaporean companies that owned and operated the Motor Vessel (MV) Dali container ship, have agreed to pay $102m to resolve a civil claim arising from the destruction of the Francis Scott Key Bridge. During the early morning hours of 26 March 2024 the MV Dali left port on its way to Colombo, Sri Lanka. However, the vessel soon lost power, rendering its steering systems unusable. Unable to alter its trajectory, Dali smashed straight into one of the support pillars of the Francis Scott Key Bridge. The bridge immediately collapsed, causing the deaths of six people. The incident is estimated to have impacted at least 8,000 jobs and forced the closure of a waterway that caused an estimated $15m in daily losses to…

UN warns that current climate policies risk catastrophic 3.1°C global temperature rise

The continuation of current climate policies by governments around the world will lead to a “catastrophic temperature rise of up to 3.1°C”, the United Nations Environment Programme (UNEP) has warned. The 2015 Paris Agreement saw countries commit to keeping global warming to an absolute maximum of 2°C above pre-industrial temperatures, and ideally no more than a 1.5°C rise. But a UNEP report found that nations would need to commit to cutting their annual greenhouse gas emissions by 42% by 2030 and 57% by 2035 in the next round of nationally determined contributions (NDCs) – and back this up with rapid action. If such commitments are not achieved, the 1.5°C goal will be gone “within a few years”. Updated NDCs are to be submitted early next year ahead of the COP30 climate talks in Brazil…
