‘No time to waste’: Tokyo makes solar panels mandatory for nearly all new homes

‘No time to waste’: Tokyo makes solar panels mandatory for nearly all new homes

Nearly all houses in Tokyo will have to install solar panels after April 2025.

The regulation – passed by the Japanese capital’s local assembly on Thursday – requires 50 major construction firms to equip homes of up to 2,000 square metres with renewable energy power sources.

The rule will help the city transition to green energy, city counsellors declared.

“In addition to the existing global climate crisis, we face an energy crisis with a prolonged Russia-Ukraine war,” said Risako Narikiyo, a member of the local assembly.

“There is no time to waste.”

 

Why is Tokyo making solar panels mandatory?

Tokyo is the world’s largest city, with a population of nearly 14 million people in its central metropolitan area. Per year, its residents emit an average of 8.6 tonnes of CO2 each.

The IPCC recommends that to meet our decarbonisation goals we should exceed no more than 2.3 tonnes of carbon each, per year.

Tokyo hopes to bring down its emissions footprint significantly in the coming decades. The city’s Metropolitan Government aims to halve greenhouse gas emissions by 2030 compared with 2000 levels, and to be emission-free by 2050.

But Tokyo lags in its uptake of renewable energy. Just four per cent of buildings with the capacity for solar panels currently have them.

The new rule will help change this.

Overall, the measure will save residents money, the metropolitan government says.

The 4 kilowatt panels will cost around 980,000 yen (€6,725) to install, but the government estimates that this will be covered by electricity sales revenue within 10 years. Subsidies will reduce this pay off time to around six years.

Weetabix to create roadmap to deliver zero-carbon breakfast cereal

Weetabix to create roadmap to deliver zero-carbon breakfast cereal

The roadmap will utilise the results of extensive carbon studies undertaken by the company in partnership with its farmers. These studies will help outline carbon-saving farming techniques associated with the growing and harvesting of wheat.

The first study has already been completed, with Weetabix working with 17 of its top farmers who account for a third of wheat supplied to make Weetabix biscuits. The study found that last year’s harvests were between 40% to 50% lower than the standard emission factors for UK wheat production, which Weetabix had been using in previous reporting calculations.

The company will work with the Map of Ag global data platform to gain best practice insight from the agricultural industry. It will also simplify data collection from farmers to improve carbon data accuracy and identify areas of improvement.

Weetabix has not set a deadline for the creation of this roadmap.

Weetabix’s technical director John Petre said: “We’re really proud of the study’s results and the work our Growers’ Group has put into reducing their emissions but we know that this is just the start of what’s required to significantly lower our overall carbon footprint. We want to get to a place where we can empower customers to use their buying power to choose lower carbon products.

“All of the work we’re currently doing with our farmers and across the business to reduce our carbon footprint will hopefully lead to producing a zero carbon box of Weetabix. That’s ultimately our goal.”

The company has also formed a collective of British farmers that are all located within 50 miles of its Northamptonshire factory to help reduce transport emissions and assist with on-the-ground expertise for growing quality. Since the collective was introduced in 2010 the group has involved more than 350 local farmers growing approximately 75,000 metric tonnes of wheat each year.

Weetabix will repeat the carbon assessments with more farmers over the coming years as part of a roadmap to procure carbon-neutral wheat. It will also work with smaller groups of growers to see how new technologies, such as precision nitrogen applications and soil assessments, can assist in its carbon reduction strategy.

The carbon analysis has been included in the company’s latest sustainability report, which also stated that Weetabix has saved more than five million litres of water as part of an efficiency and reuse drive at manufacturing sites.

The report also highlighted that Weetabix had secured a new contract that will supply its site with 100% renewable electricity until 2025.

Last year, edie spoke to Weetabix’s John Petre, who also heads up the business’s sustainability work, to find out more about the company’s sourcing and plastics commitments.

Plans announced for 30MW green hydrogen hub in Pembrokeshire

Plans announced for 30MW green hydrogen hub in Pembrokeshire

Norwegian energy developer Statkraft has announced plans to develop a major green hydrogen production hub at the site of disused rail storage in Pembrokeshire.

The company is looking to transform the site of the former Royal Navy Armaments Depot into a green hydrogen production capacity of around 30GW. The hydrogen generated there, using electrolysis, would be used to serve the transport, manufacturing and industrial sectors.

Renewable electricity to serve the Trecwn Green Energy Hub will be generated from three onshore wind turbines and a ground-mounted solar array under Statkraft’s plans.

 

 

Statkraft told edie that it is hoping to submit the plans by the end of 2023. If the planning process runs smoothly, the site could be operational by the end of 2026. Around 5,000 homes and businesses in the local area will be contacted by Statkraft in the coming weeks asking if they would like to participate in consultations.

Statkraft UK’s head of RES eFuels and European wind and solar, Matt Kelly, said the project “presents an exciting opportunity to produce homegrown green energy for local use and has the potential to act a catalyst for the redevelopment of Trecwn Valley.”

The UK Government has committed to growing national low-carbon hydrogen production capacity to 10GW by 2030. At least half of this will need to be green. Hydrogen is considered necessary to the net-zero transition, for decarbonising hard-to-abate sectors such as heavy transport and heavy industry. It produces no greenhouse gases at the point of combustion. However, most global production is currently fossil-fuelled, meaning that it is not a low-carbon solution across the lifecycle.

 

Funds and accelerators

In related news, Hy24 Partners – a joint venture from investment firms FiveT Hydrogen and Ardian – has closed what it claims is the world’s largest infrastructure fund for the low-carbon hydrogen sector to date.

The €2bn fund will be used to invest across the hydrogen value chain. As well as production, storage and distribution will be supported.

Among the investors in the fund are TotalEnergies, Air Liquide, Airbus, AXA and Allianz. In total, it attracted more than 50 investors from 13 countries.

Hy24Partners estimates that the fund will enable the deployment of up to €20bn of investment within a six-year period.

Elsewhere, the Carbon Trust has announced a new clean hydrogen accelerator with backing from the UK Government’s Department for Business, Energy and Industrial Strategy (BEIS).

Modelled on the Trust’s offshore wind accelerator, the aim of the project is to help achieve economies of scale for clean hydrogen, so that it becomes cost-competitive with the grey (fossil) hydrogen that dominates global markets today.

The accelerator will convene players across the British hydrogen value chain for innovation programmes. It will cover all production methods which can comply with BEIS’s Low-Carbon Hydrogen Standard.

“This new clean hydrogen accelerator fills a gap in the current innovation landscape by focusing on stimulating the supply chain,” said the Carbon Trust’s chair Baroness Brown.

At this point, the Carbon Trust is calling for new industry participants to join the accelerator. Its first step will be to shape a plan for innovation programmes.

Major milestone for Greek energy as renewables power 100% of electricity demand

Major milestone for Greek energy as renewables power 100% of electricity demand

Renewable energy met all of Greece’s electricity needs for the first time ever last week, the country’s independent power transmission operator IPTO announced.

For at least five hours on Friday, renewables accounted for 100 per cent of Greece’s power generation, reaching a record high of 3,106 megawatt hours.

Solar, wind and hydro represented 46 per cent of the nation’s power mix in the eight months to August this year, up from 42 per cent in the same period in 2021, according to Greece-based environmental think-tank The Green Tank.

Green Tank called it, a “record of optimism for the country’s transition to clean energy, weaning off fossil fuels and ensuring our energy sufficiency.”

“European countries like Greece are rapidly accelerating away from fossil fuels and towards cheap renewable electricity. The milestone reached by Greece proves that a renewables-dominated electricity grid is within sight,” Elisabeth Cremona, an analyst at energy think tank Ember, told Euronews Green.

“This also clearly demonstrates that the electricity system can be powered by renewables without compromising reliability. But there remains more to do to ensure that renewables overtake fossil fuels in Greece’s power sector across the whole year.”

 

What’s the big picture for Greece’s energy transition?

It’s a significant milestone in the history of the country’s electricity system, and follows the bright news that renewables fully met the rise in global electricity demand in the first half of 2022.But Greece’s transition to clean energy hasn’t been entirely straightforward.

Like other European countries, Greece has cut its reliance on Russian gas following the war in Ukraine by increasing liquefied natural gas (LNG) imports to meet its needs. It has also boosted coal mining, pushing back its decarbonisation plan.

Using IPTO data, The Green Tank finds that renewables – excluding large hydro sources – surpassed all other energy sources, leaving fossil gas in second place as it decreased slightly for the first time since 2018.

Greece aims to more than double its green energy capacity to account for at least 70 per cent of its energy mix by 2030. To help hit that target, the government is seeking to attract around €30 billion in European funds and private investments to upgrade its electricity grid.

It plans to have 25 gigawatt of installed renewable energy capacity from about 10 gigawatt now but analysts say Athens might reach that target sooner.

IPTO has been investing in expanding the country’s power grid to boost power capacity and facilitate the penetration of solar, wind and hydro energy.

Coca-Cola bottlers aim to develop technology to capture CO2 and convert it into sugar

Coca-Cola bottlers aim to develop technology to capture CO2 and convert it into sugar

In 2020, Coca-Cola Europacific Partners (CCEP) committed to reducing net emissions across its value chain by 30% by 2030, before bringing them to net-zero by 2040. At the time, CCEP said in a statement that it is ready to go further and faster after reducing value chain emissions by 30.5% since 2010.

Going further and faster has seen its Ventures arm (CCEP Ventures) collaborate with the University of California, Berkeley (UCB) to explore novel methods of capturing carbon and then using it as a feedstock.

Speaking exclusively with edie, Craig Twyford, Head of CCEP Ventures, stated that this project (which will originally last three years) would enable the firm to support scientists and experts to hopefully deliver a viable, onsite method to capture carbon emissions from facilities and then use them in products in a bid to drive down emissions.

“I think this is incredibly exciting,” Twyford told edie. “It’s a big picture idea, but if we start thinking of carbon as not just a problem but also as a feedstock, then there’s a lot of things we can start to change.

“The way I envisage it, but obviously there’s many twists and turns along the way, is that we’d ideally be able to fit direct air capture units to each of our sites that draws down the carbon in a cost-effective and efficient way. The biggest impact will probably be if we can use this to carbonate our drinks and produce sugar, but it could have impact elsewhere.”

 

Sugar focus

CCEP is financing the three-year research programme that will be led by the Peidong Yang Research Group at the University of California, Berkeley, which will first and foremost focus on the production of sugar from onsite carbon at an industrial scale. CCEP and Twyford believe that lab-scale prototypes could be the first step in making raw materials and packaging more sustainable and with a lower carbon footprint in the long run.

Sugarcane is not only the source of most of the world’s sugar, but is also the most produced food crop in the world. Sugarcane production has increased by more than 10% in the last 10 years with the crop now being utilised outside of the food space, namely in the creation of biofuels and controversial bioplastics.

Research from food analytics company Spoonshots found that the average water footprint used to produce 1kg of refined sugar is the equivalent of two years of drinking water for one person. Additionally, firms like British Sugar have calculated that 0.6g of CO2 equivalent is produced for every gram of sugar made.

As the population continues to grow, land becomes more contested and forests burned down for agricultural processes, it is clear that innovating the agri-sector is key to combatting key megatrends like land loss and degradation, deforestation and the climate crisis.

For companies like CCEP, agricultural ingredients, including sugar, can account for around 25% of the firm’s overall carbon footprint. Tackling emissions associated with agri-ingredients will be key to reaching net-zero.

Twyford points out that this innovation could also assist in reducing “some of the largest carbon contributors” across the value chain, namely by saving on raw and finite materials for things like packaging – by turning carbon into PET plastic and reducing the need for crude oil – and fuel and reducing transportation and logistics costs due to the onsite aspect of the project.

 

 

Supply chain innovation

Given that the majority of CCEP’s Scope 3 emissions are in the supply chain, the company is aiming to help all of its strategic suppliers set science-based targets and transition to 100% renewable electricity. For ingredient and packaging-related emissions, the company will accelerate plans relating to sustainable agriculture and 100% recycled plastics. Some life-cycle analyses have found that soft drinks bottles made using 100% post-consumer-recycled plastic generate 40% less CO2e than virgin plastic bottles.

Twyford stated that this innovation would likely have the biggest impact on its Scope 3 aspirations, but that there were still plenty of challenges to overcome.

“There are some hurdles but it think [the research team] can overcome them,” Twyford said. “The challenges are around selectivity and efficiency and creating the right glucose. So the first three years will be seeing how these challenges can be overcome. But [the team] has a roadmap for this and 2025 will come around quickly, at which point we’ll start asking ‘where do we go from here’?”

While the success of the initial research hinges on overcoming barriers, the long-term ambition for this project is scalability. Twyford believes that having an organisation as large as CCEP, which serves 1.75 million customers across 29 countries, will create some confidence in the carbon capture market which, to date, has looked at larger projects between a cluster of organisations and sites.

Crucially, CCEP believes that this vision could be shared across the industry, helping other firms to decarbonise at a pace on the road to net-zero.

“Everyone needs to learn off everyone,” Twyford said. “So if these direct air capture systems can really be used to help us view carbon as a valuable feedstock then this can be a solution that will help a lot of industries. I think these types of solutions will be industry-wide eventually.

“For us, we think that if we can take on a leadership role to back this, then others may look at us and view this as something that is serious and can be scaled.”

CCEP is not the only firm with this view. Carpet manufacturer, Interface, for example i forging ahead with its Climate Take Back strategy, which is also filled to the brim with moonshot goals. It focuses on “bringing carbon home and reversing climate change” and to “stop seeing carbon as the enemy, and start using it as a resource”. Indeed, many industrial firms have switched their mindset to stop “demonising” carbon and instead realise the potential that is could have as a key material building block.

Twyford ends by reiterating that this will not see the company become sugar manufacturers and that any success will require the expertise of its existing supply chain to help share advice and best practice.

To this end, earlier in the week, CCEP confirmed the creation of a sustainability-linked supply chain finance programme that will be operated by specialist food and agri-bank Rabobank.

The new finance programme will reward suppliers that make improvements on sustainability across the business and will feature sustainability-linked KPIs that, if met, will create discounts against the initial funding rate.
