Repowering Coal


Advanced Construction and Manufacturing Methodologies for New Nuclear Build

Nuclear Energy Agency (NEA)


March 17, 2022

This NEA workshop explored recent experiences and the development of construction and manufacturing techniques—focusing on near-term advances in nuclear construction, while also providing some indication of more long-term improvements that could be made on the basis of design innovations. Finally, workshop participants examined the role of regulators as well as codes and standards organisations to facilitate a wider adoption of advanced construction and manufacturing methodologies. Day 2 of the workshop was opened by Kirsty Gogan, who urged the nuclear industry to lower costs substantially through programmatic learning—because nuclear energy is needed in order to reach Net Zero, and at present: "What we are looking at now is a 3-4º and we have no plan to avoid that outcome." Eric Ingersoll presented TerraPraxis' Repowering Coal project in the Session 3: Panel on improving constructability with small, modular and innovative nuclear designs.

TerraPraxis at CERAWeek



March 8, 2022

CERAWeek brings together global leaders to advance new ideas, insight and solutions to the biggest challenges facing the future of energy, the environment, and climate. Now in its 40th year, CERAWeek is widely considered to be the most prestigious annual gathering of CEOs and Ministers from global energy and utilities, as well as automotive, manufacturing, policy and financial communities, along with a growing presence of tech. It has been described by the Financial Times as the "the Davos of energy," and by Politico as the “industry’s Super Bowl.” CNBC called it “the world’s preeminent energy conference.” CERAWeek was rated one of the top five overall “corporate leader” conferences in the world.​ Kirsty Gogan of TerraPraxis presented Repowering Coal at the Carbon Management Hub Pod #4 on March 8, if you are a registered CERAWeek user, watch it on demand here; and on March 10 on a panel on how advanced heat sources are leading to new interest. Moderated by Chad Singleton from IHS Markit, with John L. Hopkins from NuScale Power LLC and J. Clay Sell from X-Energy.

Designing the Terawatt Transition: Repowering Coal

Effective Environmentalism


February 27, 2022

Watch this presentation by Kirsty Gogan and Eric Ingersoll of TerraPraxis to the Effective Altruism community about why they founded TerraPraxis—to come up with Climate 2.0 strategies that address the actual risks to the energy transition—cost, speed, scale, space, and political support—these are the obstacles that are standing in the way of achieving the progress on decarbonization the world needs and expects. These risks include public opposition and legal constraints to the future development of renewable energy. For instance, two-thirds of the counties in the U.S. state of Iowa have added restrictions or prohibitions to future wind development; this is true for many states across the US. Based on analysis TerraPraxis and its partner LucidCatalyst performed with McKinsey, it is clear that there is very little potential for onshore wind development left in Germany. However, climate modelers do not take this into consideration and continue to model large additions to wind resources, allowing policy makers to believe we are on the right track when in fact the reality is very different. Along similar lines, TerraPraxis is leading a project to repower the world's 2TW of coal plants, which make up the single largest source of global carbon emissions.

Derisking the TeraWatt Transition

Climate Action Solution Centre


November 3, 2021

TerraPraxis hosted this high-level event in parallel with the UN Climate Change Conference (COP26)—Energy Day at Climate Action Solution Centre (CASC): De-Risking the Terawatt Transition. During the full-day event, key stakeholders revealed new near-term climate-scale strategies to compete on price and performance with fossil fuels that will break through the world’s largest and most difficult carbon emissions challenges: coal, and liquid fuels. Customers, investors and political leaders announced strategies to accelerate the affordable repowering of 2TW of coal and delivery of 100 million barrels/day of carbon-neutral liquid fuels. These large-scale solutions will repurpose trillions of dollars of existing infrastructure to continue supplying reliable energy, without emissions, and can advance groundbreaking progress toward Net Zero by 2050. The sessions were videotaped and can be viewed at the link below.

From Commitments to Actions: the sprint to net zero

CleanTech Forum Europe


October 5, 2021

Eric Ingersoll and Kirsty Gogan, Co-Founders of TerraPraxis, joined the panel on Big Ideas: is repowering coal the largest carbon abatement opportunity in the world? At the start of 2020 we argued that urgent actions, unusual strategies and unexpected allies would need to be a feature of the 2020’s, if we are to get on track to meet decarbonisation goals. We have been looking for such ever since and believe we have found a big idea to bring to everyone’s attention. The live program was kicked off with a sneak preview of this idea with others.

Flexible Nuclear Campaign for Nuclear-Renewables Integration (CEM12)

Clean Energy Ministerial, Event Video


June 4, 2021

Watch Kirsty Gogan and Eric Ingersoll of TerraPraxis in a video of this event led by the NICE Future initiative at the 12th Clean Energy Ministerial (CEM12), which took place in Chile (May 30 – June 4, 2021). The discussion expanded on nuclear technology’s system flexibility benefits, presenting new applications that target hard-to-abate sectors and enable re-use of existing infrastructure without emissions, including the opportunity to repower coal fleets making them cleaner and more flexible. Note: Eric presents the Repowering Coal project at 42.30 mins and then Kirsty has a brief conversation with Rumina Velshi, President and CEO of the Canadian Safety Nuclear Association.
