Slow train coming: only a genuine shift to rail will put NZ on track to reduce emissions

-Philip Laird, Honourary Principal Fellow, University of Wollongong Both the Labour government and the opposition National Party have now released major transport polices that put the emphasis on maintaining and expanding roads. The cost and priority of various projects will clearly be an election issue. But at the heart of the debate lies an inconvenient truth about climate change: encouraging road transport while needing to reduce carbon emissions simply does not add up. We can see this tension in transport agency Waka Kotahi’s own policy statements: road safety and better travel options on the one hand, addressing sustainability on the other. But transport is responsible for 17% of New Zealand’s total greenhouse gas emissions. Furthermore, road vehicle use has been increasing, as has the popularity of larger cars and SUVs that create more emissions per kilometre. Road congestion has become worse, with the popular response being to expand road capacity. Hence the present government’s recently announced plans for a second harbour crossing in Auckland involving two road tunnels. And the main thrust of National’s Transport for the Future policy is on more urban and intercity roads. Both Labour and National favour a second Mount Victoria tunnel in Wellington. In the background sits the government’s Rail Plan, which sets out the “vision and priorities for rail over the next decade and beyond”. But given the clear need for New Zealand’s transport policies to change, the planned improvements need to be on a fast track. Light rail right next door Cars and planes are convenient, but both have low energy efficiency compared to rail. Data source: Greenhouse gas reporting: conversion factors 2019 A car’s carbon emissions per passenger kilometre can be around four times that of domestic rail (as shown by the graph above, based on UK data). The government’s transport plans for Auckland do include light rail, but National has promised to scrap the […]

Kayasand receives backing from NZGIF to reduce carbon emissions from concrete

Kayasand, a distributor of premium sand manufacturing technology, is opening its first V7 high-technology manufacturing demonstration plant in New Zealand, which uses waste products such as recycled glass, concrete and slag, and turns them into premium sand for concrete. Kayasand has received the backing of New Zealand Green Investment Finance (NZGIF) via a $3.5 million equity investment. The green investment bank was established to accelerate investment that helps reduce greenhouse gas emissions. A further $1.8 million of private investment has been secured alongside the NZGIF investment bringing the total raise to $5.3 million. Natural sand supplies are becoming harder to access and traditional concrete manufacturing processes, including the impacts of sand dredging on coastlines such as Pakiri, 100km north of Auckland, are not sustainable over the longer-term. Dr Bram Smith, Kayasand General Manager, says “Our technology can reduce or in cases eliminates the need for natural sand dredging. It uses by-products and recycled materials such as quarry crusher dust and recycled glass to manufacture a sand of such quality that it makes stronger concrete than natural sand when mixed with cement. Our goal is to reduce carbon emissions from concrete production by up to 20% using this method.” Kayasand technology is used in over 300 plants across Japan, China, India, and Australia. NZGIF Chief Executive, Craig Weise, says the deal is an important step and is a boost for the construction sector and consumers who are eagerly looking for more sustainable building materials. He says, “Auckland’s infrastructure requirements alone are projected to be $26 billion over the next decade and if New Zealand is going to meet its CO2 emission reduction targets, we need to find alternative manufacturing and building methods. We are delighted to invest in Kayasand to help deliver its services to the construction sector and to support […]

Matahio Energy completes acquisition of onshore assets in Taranaki

Matahio Energy has completed the acquisition of a portfolio of six onshore oil and gas licenses in the Taranaki Basin, NZ. Matahio will be the operator of these licenses, holding 100% participating interest in four licenses, and 70% interest in the remaining two licenses. Of the six licenses, three are currently producing. The sale and purchase agreement between the parties was signed in March 2022. All required approvals for the relevant New Zealand regulatory authorities have been obtained to complete this transaction. Key highlights of the transaction: – Operatorship of two fields, namely Cheal and Sidewinder, which are currently producing a total of 1.4 Kboepd (thousand barrels of oil equivalent per day), net to Matahio. Cheal and Sidewinder are well-established, prolific fields, which have produced over 5 MM bbls (million barrels of oil) to date, since the first oil in 2008. – Matahio is adding 2 MM boe (million barrels of oil equivalent) 2P reserves (Net, effective date 1st January 2023). At prevailing oil prices and contemporary OPEX rates, the Cheal and Sidewinder fields are expected to generate positive cash flow until 2030. The New Zealand business’s EBITDA for the calendar year 2022 was NZD$29 MM. – The transaction also includes full technical and operational teams, based in New Plymouth, who have a track record in delivering strong health, safety & environment (HSE) and production performance. Most notably, recent production optimisation efforts have resulted in production rates returning to 2015 levels without drilling any new wells. – Matahio has crafted a multi-year development programme consisting of infill and step-out drilling as well as the appraisal of newer fields in the Puka license (which was 100% acquired by Matahio) to be tied back to existing operated infrastructure. This organic growth programme targets an additional 3.8 MM boe and, if successful, will […]

Battery power plus product stewardship for a brighter future

By Dominic Salmon, 3R Group Business Development – Sustainable Solutions The transition away from fossil fuels will rely heavily on large batteries – it’s estimated that EVs and stationary energy storage batteries can enable 30% of the emissions reduction needed in the transport and energy sectors. The conversation can often steer towards electric vehicles, but large stationary batteries are just as important. Large batteries are not yet widely used in New Zealand outside of EVs and hybrid vehicles. However, the potential applications for stationery storage are huge. These range from use in homes to store excess solar power, to national power grid stabilisation, upgrading old, inefficient battery systems and even as back up for key infrastructure in the event of natural disasters such as Cyclone Gabrielle. The range of stakeholders in this area is wide, from EV and home solar system owners (and potential owners) to energy generation companies, vehicle and battery importers, recyclers and, well, just about anyone who has energy needs. Like all solutions though, thought needs to go into preventing unintended consequences. In the case of batteries, it’s ensuring they are ethically and sustainably produced and don’t become a problematic waste stream at end of life. While small markets like New Zealand, which don’t mine the minerals or manufacture large batteries, can’t have a direct impact on their production, we can ensure they are used as efficiently as possible. Importers, retailers and consumers can also use tools like the Global Battery Alliance’s battery passport to track battery health and environmental impact and create demand for ethically and sustainably manufactured batteries. Making this transition obviously isn’t straight forward but there is a significant amount of work being done, including in Aotearoa New Zealand by the Battery Industry Group (B.I.G). Batteries in the Land of the Long White Cloud […]

Mitigate or adapt? With climate change it’s both

If you’re dealing with the aftermath of the weather events, as many are, we wish you well. Adapting to climate change. Since the disastrous weather earlier this year, it’s a term we’ve heard regularly in the mainstream media. What does adapting involve? Why does it matter? As a manufacturer, do you need to keep reducing (mitigating) climate change as well as adapting to it? (The answer to that last question: an emphatic yes!) This article explains why mitigating and adapting to climate change must go hand-in-hand for New Zealand manufacturers. But first, the science Let’s start with the global picture. The Intergovernmental Panel on Climate Change is adamant: a 1.5°C increase in global temperatures over pre-industrial levels will adversely affect the world’s climate. A 2°C increase will be more serious still. The cause of this warming? Greenhouse gases (GHGs). Zoom in to Aotearoa New Zealand. Scientists at the National Institute of Water and Atmospheric Research (NIWA) and University of Waikato are convinced that Cyclone Gabrielle’s devastating rainfall is an example of climate change. The cause? Global warming, due to GHGs, increases air temperatures. Warmer air holds much more water vapour. When this vapour cools, it rains. Photo credit: Kelly Sikkema on unsplash. What does mitigating climate change involve? Think of mitigation as the fence at the top of the cliff. Mitigation is about addressing the causes of climate change by reducing the GHGs we emit. If you’re a manufacturer, it could involve reducing the carbon in your products or moving your factory to renewable electricity. To date, governments and businesses have focussed on mitigation – with good reason. We all benefit when we reduce climate change. What does adapting to climate change involve? If mitigation is the fence, adaptation is the ambulance. With a poorly maintained fence (an atmosphere damaged by […]

Feeling our way towards hydrogen

-Tina Schirr, Executive Director, BusinessNZ Energy Council Right now hydrogen is getting a lot of attention. Many countries are focusing on producing hydrogen for fuel, or procuring it, or planning for its future use. Hydrogen fuel is highly desirable – clean hydrogen produces none of the harmful emissions of other energy sources. So hydrogen is potentially a very good energy source for powering our post-carbon world. But there’s a catch – production of hydrogen is not economic at present and currently can’t be produced cost-effectively. As a result, countries are taking the initiative in different ways as they feel their way towards a hydrogen-powered future. Recently, the World Energy Council (WEC) released a report on hydrogen – Hydrogen on the Horizon: Ready, Almost Set, Go?: the BusinessNZ Energy Council, WEC’s representative in New Zealand, contributed to the report, along with 128 other countries. The report highlights the global activity that’s occurring in the development of hydrogen as a fuel source. A number of countries in the Middle East, North Africa and the Americas are focusing on producing hydrogen. Others, in Asia and Europe, are more focused on procuring it. Their reasons for looking to hydrogen are varied – including its potential to diversify energy sources, decarbonise economies, allow for repurposing infrastructure, and to grow green jobs and green economies. Some countries – notably Germany, Japan, South Korea and Singapore – are partnering with others to ensure they can achieve global hydrogen supply chains and adequate supply once hydrogen becomes cost-effective to produce in significant quantities. New Zealand is becoming integrated into such partnerships, signing bilateral partnership agreements with Japan and Singapore and partnering with Germany on green hydrogen research projects. New Zealand is also among the countries that are seeking ways to produce hydrogen cost-effectively. Last week Contact Energy and […]
