Ditch Nuclear And Save $860 Million With Grid Flexibility, U.K. Told 

At-a-Glance

According to the report from Finnish energy tech firm Wärtsilä, the U.K. would stand to save $860 million per year if, instead of new nuclear power, the government backed grid flexibility measures, such as battery storage and thermal generation. That equates to a saving of about $33 dollars per British household per year. Crucially, the analysis revealed that even if energy generation was to remain the same as it is today, Britain could increase renewables’ share of that generation to 62% simply by adding more flexibility.

Key Takeaways

  • According to the Wärtsilä report, Germany at one point paid almost $1.1 million per hour to export 10.5 gigawatts of electricity. Such inefficiencies, Ville Rimali, growth and development director at Wärtsilä Energy said, were indicative of inflexible electricity systems—while countries that had built flexibility into their power grids had no such issues.
  • On the other hand, investing in nuclear power could, according to Wärtsilä, entrench an inflexible grid while making renewables such as solar and wind less cost-effective.
  • Wärtsilä’s recommendations appear to align closely with those of the International Energy Agency (IEA), which has stated that, as economies move away from fossil fuels, “power system flexibility has become a global priority.” Subsequently, according to a report released by the agency last month, much faster deployment of grid flexibility will be required if countries are to achieve their decarbonization targets.

Path to 100% Perspective

In the “Optimising the UK’s Shift to a Renewable-Powered Economy, Wärtsilä recommends a three phase strategy to accelerate a cost-optimal shift to 100% renewable energy and economic decarbonisation. 

  1. Support faster renewable energy deployment to achieve 80% renewable generation by 2030. 
  2. Increase investment in flexibility to unlock renewable energy and deliver a cost-optimal transition for consumers. 
  3. Future-proof today’s decisions to enable future technologies – such as Power-to-X – to achieve 100% renewable energy before 2050

Renewable Electricity Set To Power Past Coal And Gas By 2025

At-a-Glance:

Global economic growth has dropped this year because of COVID-19 and the energy sector has been among the hardest-hit, with oil prices at one point turning negative as demand slumped.

However, one part of the energy industry has defied the downturn – and is set to post record growth this year and next. Cost reductions and sustained policy support are set to drive strong growth in renewable energy. By 2025, renewables will have usurped coal to become the biggest source of electricity generation globally. To learn more, read “Renewable Electricity Set To Power Past Coal and Gas By 2025.” Reading this article may require a subscription.

Key Takeaways:

  • The International Energy Agency (IEA) Renewables 2020 report says that almost 200GW of new clean power capacity will be installed in 2020, almost 90 percent of all new power capacity around the world.
  • Renewable electricity generation will increase by 7 percent globally in 2020, underpinned by the record new capacity additions, the Agency says. This growth comes despite a 5 percent annual drop in global energy demand, the largest since World War II.
  • India’s renewable energy sector is set to double in 2021.
  • Global growth in renewable capacity in the first 10 months of 2020 is already 15 percent higher than the same period last year, despite the pandemic, and growth is set to continue.
  • But while renewables in the power sector are going from strength to strength, the COVID crisis has hit electric vehicles and renewable heat hard

Path to 100% Perspective:

As wind and solar power become increasingly cost-competitive, investments in traditional, inflexible base load plants such as large coal, nuclear, and gas combined-cycle plants are declining. This signals an end to the era of large, centralized power plants that run on fossil fuels.

Global financial trends reflect this dramatic shift, with renewable generation attracting more investment dollars than fossil-powered generation year after year. In 2018, investment in renewable power capacity was about three times higher than the amount invested in new coal- and gas-fired generation combined, according to the global renewable energy organization REN21. Worldwide investment in renewables has exceeded $230 billion for nine years in a row.

Why ‘Carbon Neutral’ Is the New Climate Change Mantra

At-a-Glance:

Becoming carbon neutral — also known as climate-neutral or net zero — is now a legal requirement in some countries, while European authorities are adopting legislation to become the first net zero continent. Even oil companies are getting in on the act. Buildings, airlines and events have also made the pledge, while investments groups managing almost $5 trillion of assets have committed to having carbon-neutral portfolios by 2050.To learn more, read Why ‘Carbon Neutral’ Is the New Climate Change Mantra.” Reading this article may require a subscription.

Key Takeaways:

  • What is carbon neutral? It means cutting emissions to the very limit and compensating for what can’t be eliminated.
  • What are carbon offset credits? Developed by the United Nations and non-profit groups, these let the buyers emit a specified amount of greenhouse gas, which is offset by using the money raised to fund carbon-reduction projects such as reforestation.
  • Who’s trying to be carbon neutral? Dozens of countries have committed to go net zero, or at least outperform carbon-reduction targets set out in the landmark 2015 Paris Agreement on climate change.
  • What’s driving this? CO2 pollution is still rising — 2019 was another record — and is unlikely to peak before 2040, driven by growing use of fossil fuels, says the International Energy Agency.
  • How will the goals be reached? To get anywhere close to net zero by 2050, the world must invest $2.4 trillion in clean energy every year through 2035, according to the UN’s Intergovernmental Panel on Climate Change. Much will ride on technologies that on the grand scale required are as yet unproven, including carbon capture, using hydrogen as fuel and removing carbon dioxide from the atmosphere.

Path to 100% Perspective:

Understanding the evolving terminology is useful, but embracing a plan that is possible, practical and affordable will combine knowledge with measurable results. As organizations add renewable energy to their net zero goals, it is important to develop a power system with flexibility, reliability and sustainability in mind. Renewable energy can actually generate renewable fuels that can be used to create a sustainable grid with a path to faster decarbonization.

This is How the Government Can Ramp Up Climate Tech Investment

At-a-Glance:

The last couple of weeks have brought a steady stream of new pledges to achieve net-zero carbon emissions within the next handful of decades. And yet a report released in September, by the International Energy Agency, estimated that roughly half of the technologies that will be needed to get to net zero globally by 2050 aren’t even commercially available yet. The secret of deep decarbonization is that it won’t happen by just plugging into a wind farm or buying carbon offsets in a tropical forest. Without new technologies, it will be impossible to rein in emissions from the most-carbon intensive sectors of the economy such as heavy industry and long-distance transport. To learn more, read “This is How the Government Can Ramp Up Climate Tech Investment.”  (Reading this article requires a subscription.)

Key Takeaways:

  • Physicist Varun Sivaram sees the first step is to establish a National Energy Innovation Mission and create a White House Task Force to coordinate spending across different federal agencies. Sivaram and his team include a draft executive order in the report so the next administration can just plug and play.
  • Step two is to ramp up spending on energy innovation research and development from the current rate of about $9 billion a year to at least $25 billion by 2022.
  • The plan breaks down decarbonization into 10 categories where breakthroughs must occur. These include clean fuels, clean agricultural systems, carbon capture use and sequestration, and carbon removal.
  • One of the most persuasive moments in the report comes in a chart showing the disconnect between the sectors in the U.S. responsible for emissions and the corresponding research budget through the Department of Energy. Electricity produces 27% of emissions but gets 47% of the research dollars, while industry produces 22% of the emissions but receives 6% of the innovation funding.
  • The proposed budget would remedy that by adding money to underfunded areas, such as tripling the money for carbon capture from $115 million a year to $300 million.

Path to 100% Perspective:

Government economic stimulus must go beyond merely boosting the amount of renewables, but should also support system flexibility. We don’t just need wind turbines and solar panels but also energy storage, optimization platforms and flexible power plant technology to balance the influx of renewables. Energy storage and digital optimization is already becoming essential as we increase the amount of renewables on the grid to manage the volatility of wind and solar. Flexible gas engine technology is ready to use future fuels such as green hydrogen and synthetic methane derived from renewable energy sources (Power-to-X). These will help to balance out the longer-term needs of the grid, that can’t be matched by shorter duration energy storage.
