Writing about Energy – A Companion for Writers and Readers Interested in Energy Issues

Writing about Energy is a free resource for people interested in the energy and climate discussion happening in media and policy-making. It gives the reader both the basics on energy and terminology, as well as deeper dives into various aspects of energy’s role in modern society, energy markets and such. To top it off, it offers some case studies on how we write about nuclear energy, and how we get things wrong, even in science. The book was published with RePlanet.

Shipyard Nuclear in Finland

Finland is uniquely positioned to kickstart a new industrial sector of building and operating floating nuclear power plants at its shipyards. Effective design and manufacturing at shipyards can significantly reduce the cost of reliable low-carbon energy production while offering a tremendous opportunity for exports. Finland has many necessary pieces in place, giving us an advantage over other western countries. Finnish shipyards could build new clean and reliable energy at the gigawatt-scale, each year, and do it below half the cost of on-land nuclear plants. 

This study lays out what are the opportunities and bottlenecks, and hopes to start a serious political and business discussion on whether Finland can and should be at the forefront of an enormous clean energy opportunity.

Beautiful Nuclear: Driving Deep Decarbonisation

“Nuclear is beautiful because its tiny land use and lifecycle footprint protects nature and delivers civilisation-scale, abundant clean energy. Both of these are fundamental to our future health, well-being and prosperity on this planet.”
Kirsty Gogan, co-founder of TerraPraxis, report co-author

Think Atom CEO Rauli Partanen was a co-author of the Beautiful Nuclear -report published by LucidCatalyst.

Ydinvoima Suomessa 2050 on Suomen Perusta ajatuspajan tilaama ja Think Atomin tekemä selvitys siitä, miltä näyttäisi ja mitä vaatisi päästöjen raju laskeminen ydinvoiman avulla siten että kustannukset pysyisivät maltillisina, teollisuus pysyisi Suomessa ja Suomeen jopa luotaisiin uusia teollisuudenaloja, työpaikkoja ja hyvinvointia.

One Billion tons is a groundbreaking report on the consequences of the German nuclear-exit.

One Billion tons is a report commissioned by Ökomoderne E.v. It lays out how much emissions and human lives could be saved if Germany would refrain from closing down their remaining 6 nuclear reactors (3 in end of 2021 and 3 in the end of 2022) and would close coal and natural gas instead. The answer, in short, is one billion tons of CO2

Missing Link to a Livable Climate –
How Hydrogen-Enabled Synthetic Fuels Can Help Deliver the Paris Goals

Our new report reveals how untapped options for clean hydrogen can put the world back on the pathway to the Paris climate goals

​Think Atom and our CEO Rauli Partanen contributed to this trailblazing report on the potential of and need for massive amounts of clean hydrogen that can be produced at low cost with advanced heat sources such as small nuclear reactors.

Small Reactors and Where to Use Them /
Pienreaktorit ja niiden käyttökohteet


This folder gives you the quick essentials on what are small nuclear reactors and their pros and cons, when are they coming to the market, and most importantly, what they can be used for; not just electricity, but valuable services to the power grid, district heating of cities, desalination of seawater, many industrial processes and even manufacturing of cost-effective clean hydrogen.

Sustainable Nuclear – An Assessment of the Sustainability of Nuclear Power for the EU Taxonomy Consultation 2019

Download Pdf here.


Almost half of Europe’s low-carbon energy is provided with nuclear power today. The world’s scientific consensus e.g. Intergovernmental Panel on Climate Change (IPCC) concludes that nuclear energy has an essential role in low-carbon energy production and climate mitigation.

If the EU Sustainable Finance Taxonomy excludes nuclear, it may result in both new build and life extensions for existing fleet being much more difficult to finance. This report was prepared for the European Commission Technical Expert Group on Sustainable Finance, as well as for the international investment and financing community, to help them fairly and robustly evaluate the overall sustainability of nuclear energy as an investment. The central finding is that nuclear energy is a sustainable energy investment.

Nuclear District Heating in Finland – The Demand, Supply and Emissions Reduction Potential of Heating Finland with Small Nuclear Reactors

Published by Think Atom

From back-cover: Halting climate change demands rapid and deep decarbonization of our energy systems. Those energy systems go much beyond the electricity grid, and they also have distinct characteristics and demands. District heating is one of these systems. These local heating networks are currently served by combusting fuels in heat-only of combined heat and power (CHP) capable plants.

This study looks at the potential to deeply cut emissions in district heating networks with small nuclear reactors (SMRs) in the Finnish context, with a case study also included for Poland. What are the demand profiles of these networks, and how well they can be met with upcoming SMRs?
ERRATA: The printed version regrettably had an error regarding heat consumption in Warsaw, Poland. Instead of 27 TWhs, Warsaw today uses around 7 TWhs of heating annually. This pdf version has been updated with official projected demand for 2040, which is around 14 TWh/year. The models/graphs also have half the amount of reactors (but with same capacity / reactor).


Decarbonizing Cities: Helsinki Metropolitan Area – Providing district heating, power and transportation fuels with advanced nuclear reactors

From back-cover: This report is one of the first studies to explore how we could use small, advanced nuclear reactors to achieve an almost complete decarbonization of our society.

It explores how we can construct a fleet of nuclear reactors to provide district heating, power and hydrogen in a flexible and cost-effective way. The scope of the study covers the Helsinki Metropolitan area with a projected population of around 1.5 million people by 2050. Using combined heat and power (CHP) and high temperature electrolysis (HTSE), the significant seasonal variations in energy demand can be met while still using the nuclear reactors at high capacity.

We need to proceed on a society-wide deep decarbonization as fast as possible. This study finds that using innovative nuclear reactors as a significant part of the solution will offer huge benefits to achieve decarbonization of electricity, transport and heating.
