Polar Night Energy’s Heat Storages Have a Massive Potential to Reduce Greenhouse Gas Emissions According to Mission Innovation’s New Assessment

Polar Night Energy’s sand-based high temperature seasonal heat storages may save over 100 Mt CO2e per year in 2030 according to Mission Innovation’s report. The amount is approximately 3 % of the current EU emissions.

See below for the Finnish version.

Mission Innovation has made an assessment about the potential avoided greenhouse gas emissions per year in 2030 enabled by Polar Night Energy’s sand-based high temperature seasonal heat storage and other similar competing innovations.

The result is ≈100 Mt CO2e/year in 2030. Mission Innovation ranks the results according to orders of magnitude, and this result places Polar Night Energy in the second highest category. No innovations have yet been ranked in the highest category. Polar Night Energy’s exact value in the assessment is 169.8 Mt CO2e/year in 2030.

– It means that according to the estimate our heat storages could potentially save almost double the CO2e emissions of the today’s New York City, says Polar Night Energy’s CEO Tommi Eronen.

Mission Innovation is a global initiative of 22 countries and the European Union, seeking to accelerate global clean energy innovation and make clean energy widely affordable and reliable. It was launched at the Paris Climate Conference in 2015.

Mission Innovation’s Avoided Emissions Framework was launched in conjunction with the release of the IPCC’s Special Report in 2018 and is increasingly seen as the de facto standard for impact assessments. Mission Innovation’s analysis opens a more profound dialogue between companies, investors, and different industries.

– It is great to see that our company has been recognized as having potential to really make a big impact for carbon neutral world, says Tommi Eronen.

Polar Night Energy’s heat storage enables the storage of renewable energy when energy production conditions are beneficial. The stored renewable energy can later be used in different energy demanding processes, replacing fossil-based combustion technologies that are common nowadays for heating and electricity production.

– The avoided emissions assessment of our solution was based on the amount of predicted surplus renewable energy production. However, as was also noted in the report, we are not just a solution for inevitable excess electricity, but a catalyst for accelerating the transition from fossil fuels to solar and wind power, Tommi Eronen concludes.

In Mission Innovation’s Net-Zero Compatible Innovations Initiative (NCI), assessments are being performed following the Avoided Emissions Framework (AEF) guidance. The methodology is based on best practices and provides an estimate of the avoided emissions potential in the year 2030, taking account of the decarbonisation expected.

The NCI assessment of Polar Night Energy’s innovation was initiated by Business Finland.

Raportti: Polar Night Energyn lämpövarastoilla on valtava potentiaali vähentää ilmastopäästöjä

Mission Innovationin raportin mukaan Polar Night Energyn hiekkapohjaiset korkean lämpötilan energiavarastot voivat säästää vuosittain yli 100 Mt CO2e vuoden 2030 jälkeen. Päästösäästö olisi noin kolme prosenttia nykyisistä koko Euroopan unionin alueen päästöistä.

Mission Innovation on arvioinut Polar Night Energyn hiekkapohjaisten korkean lämpötilan energiavarastojen potentiaalisen päästövähennyksen per vuosi vuodesta 2030 eteenpäin. Arvio kertoo, että Polar Night Energyn lämpövarastoilla ja muilla saman tyyppisillä ratkaisuilla voidaan saavuttaa merkittävät päästövähennykset tulevaisuudessa.

Raportin mukaan päästövähennyspotentiaali on suuruusluokaltaan sata hiilidioksidiekvivalenttimegatonnia (100 Mt CO2e) per vuosi vuodesta 2030 eteenpäin. Tällä tuloksella Polar Night Energy pääsee arvioinnissa toiseksi parhaaseen päästövähennysluokkaan. Yksikään noin tuhannesta arvioidusta innovaatiosta ei vielä ole päässyt korkeimpaan luokkaan. Raportin antama tarkka tulos Polar Night Energyn päästösäästölle on 169,8 Mt CO2e vuodessa.

– Se tarkoittaa, että arvion mukaan lämpövarastomme voisivat potentiaalisesti säästää lähes tuplasti koko nykypäivän New Yorkin päästöt tai kolme prosenttia koko EU:n päästöistä, sanoo Polar Night Energyn toimitusjohtaja Tommi Eronen.

Mission Innovation on kansainvälinen aloite, jonka ovat perustaneet 22 valtioita ja Euroopan unioni. Sen tavoitteena on nopeuttaa kestäviä energiainnovaatioita ja tehdä puhtaasta energiasta globaalisti edullista ja luotettavaa. Aloite julkaistiin Pariisin ilmastokokouksessa 2015.

Mission Innovationin Avoided Emissions Framework -arviointimenetelmä (Säästettyjen päästöjen viitekehys) lanseerattiin yhdessä IPCC:n vuoden 2018 raportin kanssa ja sitä pidetään yhtenä vaikutusarviontien standardina. Mission Innovationin analyysi tarjoaa yhteisen pohjan keskustelulle yritysten, sijoittajien ja eri teollisuuden alojen välillä.

– On hienoa tietää, että yrityksellämme on oikeasti iso mahdollisuus auttaa hiilineutraalin maailman luomisessa, sanoo Tommi Eronen.

Polar Night Energyn lämpövarastot mahdollistavat uusiutuvan energian varastoinnin silloin, kun olosuhteet sen tuotantoon ovat otolliset. Varastoitu uusiutuva energia voidaan myöhemmin käyttää korvaamaan fossiilisia polttoaineita, joihin suurin osa nykyisestä lämmityksestä ja sähköntuotannosta perustuu.

– Ratkaisumme arvioitu päästösäästö perustuu ennustettuun uusiutuvan energian ylijäämän määrään tulevaisuudessa. Toisaalta, kuten raportissa sanotaan, emme ole ratkaisu vain ylimääräisen sähkön varastointiin, vaan osaltamme myös kiihdytämme siirtymää fossiilisista polttoaineista kohti aurinko- ja tuulienergiaa, Tommi Eronen sanoo.

Mission Innovationin Net-Zero Compatible Innovations Initiative (NCI) -aloitteessa arvioinnit tehdään Avoided Emissions Framework -arviointimenetelmällä. Menetelmä perustuu parhaisiin käytäntöihin ja mahdollistaa päästövähennyspotentiaalin laskemisen vuodeksi 2030.

Polar Night Energyn innovaation arviointi tehtiin Business Finlandin aloitteesta.

Polar Night Energy Takes Part in NewSETS – A Project Implementing Novel Storage Solutions for a Sustainable Energy Transition

A consortium lead by Flexens Oy Ab has succeeded in securing funding through the ERA-Net SES MiCall19 framework. The other consortium partners are LUT University, Polar Night Energy Oy and Pumped Hydro Storage Sweden Ab. With a total budget of 4.1 million euros, the three-year project called NewSETS focuses on novel energy storage solutions.

Launching NewSETS project – implementing novel storage solutions for a sustainable energy transition

NewSETS, short for "New energy storages promoting sustainable energy transition in societies", is all about storing energy. The project centres around two main storage types: seasonal heat storage and underground pumped hydro storage.

The former storage type is developed by the Finnish company Polar Night Energy and uses high-temperature sand to store heat. The latter, provided by the Swedish company Pumped Hydro Storage, employs conventional pumped hydro methods in a new space: underground. Both technologies present low-emission and innovative approaches to energy storage.

NewSETS links demonstrations, feasibility studies, market and system analyses with ambitious communication efforts. The underground pumped hydro storage will be demonstrated in the project, while the team will perform feasibility studies for the seasonal heat storage. In addition, the effects of the two storage types on the energy system will be comprehensively studied - also in combination with other storage solutions.

The NewSETS project aims to establish a positive outlook among energy stakeholders and make climate change mitigation efforts visible to everyone through skilful communication. It is an ambitious project rooted in international collaboration and mutual interests in a sustainable energy transition.

"NewSETS combines professionals with different perspectives on a common problem: how to stabilize energy networks with new kinds of storage solutions. The project offers us a wonderful chance to examine how our high temperature sand-based heat storage could be tailored to best serve diverse customers and applications", says Polar Night Energy’s Project Manager Liisa Naskali.

NewSETS officially started in the summer of 2021. Now, the joint communication of NewSETS is finally launched through the project’s own webpage. Juhani Riikonen, project manager, anticipates a fruitful continued collaboration.

"Looking forward to working with the consortium on this. It will be interesting to see how these storage types can benefit energy systems and complement each other in the renewable energy transition", says Riikonen.
