Shenzhen KSTAR Science and Technology Co. (KSTAR) has released details of the deployment of its new inverter technology in a 320 MW solar-water plant.

Called GSL2500C-MV and GSL1250, the inverters are 99% energy efficient and play a core role in the US100mn, 120 MW second-phase of a solar-water power plant in Cixi city, Zhejiang, China. The plant began operations in late December 2019.

Phase I of the project was a 200 MW installation at the Zhouxiang reservoirs in Cixi. Costing $250mn, this plant became active in 2017 and represents the largest solar-water facility in China to date.

Innovation for the energy sector

Inverters are an essential component for renewable energy projects as they convert DC (direct current) into AC (alternating current) which can be used in conventional electrical grids. 

KSTAR’s solution is optimised to shorten construction time, save operational costs and enable faster maintenance. The company lists the four primary advantages of its inverters as:

  1. Low overall cost - Designed to be highly energy-efficient, KSTAR’s inverters use less energy, thus reducing systems costs. 

  2. Advanced design - Structured to dissipate heat energy via an air duct, the inverters also feature a cooling fan which only activates once a maximum temperature has been reached.

  3. Resistant to corrosion - A strong necessity for a solar-water power plant, KSTAR’s tech can withstand heavy salt fog and high levels of humidity.

  4. Highly adaptable - Believing that tech should fit the situation and not vice versa, KSTAR makes its products on a turnkey basis which can be adjusted to meet a project’s specific requirements.

Enabling clean energy

KSTAR’s contribution to the 320 MW solar-water plant will help contribute approximately 352mn KWh of renewable electricity per year. 

Useful not just for its carbon mitigating potential (189,200 tonnes annually), large-scale renewable energy projects such as these can play a vital role in stabilising China’s electrical grids and create greater equality.

Speaking in a press release, Gary Ye, Vice-GM of KSTAR, said, “It is a pleasure that we supply the intelligent turnkey solutions for the big project. We are encouraged by the fact that the products have received wide attention and recognition from our industry customers, colleagues, and media.

“We will continue to work hard to meet the growing demands of our old and new customers.”

The UK must put an end to a year of climate contradictions and stop blundering on high carbon choices warns the Climate Change Committee

The UK Government must end a year of climate contradictions and stop blundering on high carbon choices, according to the Climate Change Committee as it released 200 policy recommendations in a progress to Parliament update.

While the rigour of the Climate Change Act helped bring COP26 to the UK, it is not enough for Ministers to point to the Glasgow summit and hope that this will carry the day with the public, the Committee warns. Leadership is required, detail on the steps the UK will take in the coming years, clarity on tax changes and public spending commitments, as well as active engagement with people and businesses across the country.

"It it is hard to discern any comprehensive strategy in the climate plans we have seen in the last 12 months. There are gaps and ambiguities. Climate resilience remains a second-order issue, if it is considered at all. We continue to blunder into high-carbon choices. Our Planning system and other fundamental structures have not been recast to meet our legal and international climate commitments," the update states. "Our message to Government is simple: act quickly – be bold and decisive."

The UK’s record to date is strong in parts, but it has fallen behind on adapting to the changing climate and not yet provided a coherent plan to reduce emissions in the critical decade ahead, according to the Committee.

  • Statutory framework for climate The UK has a strong climate framework under the Climate Change Act (2008), with legally-binding emissions targets, a process to integrate climate risks into policy, and a central role for independent evidence-based advice and monitoring. This model has inspired similarclimate legislation across the world.
     
  • Emissions targets The UK has adopted ambitious territorial emissions targets aligned to the Paris Agreement: the Sixth Carbon Budget requires an emissions reduction of 63% from 2019 to 2035, on the way to Net Zero by 2050. These are comprehensive targets covering all greenhouse gases and all sectors, including international aviation and shipping.
     
  • Emissions reduction The UK has a leading record in reducing its own emissions: down by 40% from 1990 to 2019, the largest reduction in the G20, while growing the economy (GDP increased by 78% from 1990 to 2019). The rate of reductions since 2012 (of around 20 MtCO2e annually) is comparable to that needed in the future.
     
  • Climate Risk and Adaptation The UK has undertaken three comprehensive assessments of the climate risks it faces, and the Government has published plans for adapting to those risks. There have been some actions in response, notably in tackling flooding and water scarcity, but overall progress in planning and delivering adaptation is not keeping up with increasing risk. The UK is less prepared for the changing climate now than it was when the previous risk assessment was published five years ago.
     
  • Climate finance The UK has been a strong contributor to international climate finance, having recently doubled its commitment to £11.6 billion in aggregate over 2021/22 to 2025/26. This spend is split between support for cutting emissions and support for adaptation, which is important given significant underfunding of adaptation globally. However, recent cuts to the UK’s overseas aid are undermining these commitments.

In a separate comment, it said the Prime Minister’s Ten-Point Plan was an important statement of ambition, but it has yet to be backed with firm policies. 

Baroness Brown, Chair of the Adaptation Committee said: “The UK is leading in diagnosis but lagging in policy and action. This cannot be put off further. We cannot deliver Net Zero without serious action on adaptation. We need action now, followed by a National Adaptation Programme that must be more ambitious; more comprehensive; and better focussed on implementation than its predecessors, to improve national resilience to climate change.”

Priority recommendations for 2021 include setting out capacity and usage requirements for Energy from Waste consistent with plans to improve recycling and waste prevention, and issue guidance to align local authority waste contracts and planning policy to these targets; develop (with DIT) the option of applying either border carbon tariffs or minimum standards to imports of selected embedded-emission-intense industrial and agricultural products and fuels; and implement a public engagement programme about national adaptation objectives, acceptable levels of risk, desired resilience standards, how to address inequalities, and responsibilities across society. 

Drax Group CEO Will Gardiner said the report is another reminder that if the UK is to meet its ambitious climate targets there is an urgent need to scale up bioenergy with carbon capture and storage (BECCS).

"As the world’s leading generator and supplier of sustainable bioenergy there is no better place to deliver BECCS at scale than at Drax in the UK. We are ready to invest in and deliver this world-leading green technology, which would support clean growth in the north of England, create tens of thousands of jobs and put the UK at the forefront of combatting climate change."

Drax Group is kickstarting the planning process to build a new underground pumped hydro storage power station – more than doubling the electricity generating capacity at its iconic Cruachan facility in Scotland. The 600MW power station will be located inside Ben Cruachan – Argyll’s highest mountain – and increase the site’s total capacity to 1.04GW (click here).

Lockdown measures led to a record decrease in UK emissions in 2020 of 13% from the previous year. The largest falls were in aviation (-60%), shipping (-24%) and surface transport (-18%). While some of this change could persist (e.g. business travellers accounted for 15-25% of UK air passengers before the pandemic), much is already rebounding with HGV and van travel back to pre-pandemic levels, while car use, which at one point was down by two-thirds, only 20% below pre-pandemic levels.
