1/ New research @lut.fi presents the first global analysis of inter-annual storage for #100RE systems in 145 regions doi.org/10.1016/j.ap.... Strategic generation overcapacity is a significantly more cost-effective solution than building massive storage.

"Solar PV system diversity largely ignored in energy scenarios" - much progress has been achieved in recent years, now it's the time to improve energy models and scenarios. @solarpapst.bsky.social @solarchase.bsky.social @mzjacobson.bsky.social @nworbmot.bsky.social @aukehoekstra.bsky.social

📰🌍🚀 Solar #PV dominates the #energy #transition, yet models often ignore current technologies. This column urges energy system modelers to align scenarios with real-world #solar PV progress, offering key studies as #inspiration.

Solar PV needs more nuanced assumptions in energy system modelling

Solar PV currently evolves as the most important source of energy. Many energy system models still do not consider technologies that are already standard in today’s solar PV market. This article provi...

13/ The insights are valuable for policymakers & industrial developers, showcasing how regions with abundant RE resources, existing industrial infrastructure & access to biogenic CO2 can support the energy transition. This strategy could attract new energy-intensive industries.

12/ The large-scale RE build-out will also generate substantial fiscal revenue for local municipalities (UN SDG 8), and position Lapland to help Finland phase out net electricity imports, enhancing national energy security within the EU.

11/ PtX units generate 5000 GWh waste heat annually. About 1226 GWh are recovered for district heating, the remaining surplus can create further value. Following Iceland, low-cost heat could be used for agriculture, powering greenhouses to enhance food security for Finland & EU.

10/ e-Methanol production is enabled at a competitive 96 €/MWh, offering an edge over other potential Arctic energy hubs by leveraging existing industrial infrastructure.

9/ The study on Lapland projects a 28% decrease in annual energy system costs and a 53% drop in electricity generation cost by 2050 compared to 2020. Lapland's existing pulp and paper industry offers biogenic CO2 for cost-effective e-hydrocarbon production.

Christian Breyer @christianonre.bsky.social · 1d

8/ By 2050, Lapland's total power generation capacity can reach 7.5 GW, with 4.5 GW wind dominating generation, alongside a jump in solar PV capacity. This mix leverages the complementary profiles of solar PV (summer sun) and wind power (winter wind) for a stable #100RE system.

Christian Breyer @christianonre.bsky.social · 1d

7/ The energy system in Lapland is strongly dominated by industrial energy demand. Expansion of power generation is largely done by wind power with solar PV investments in the 2040s.

6/ We used LUT-ESTM to simulate Finland’s energy transition & analysed Lapland’s transition within the broader national energy system. LUT-ESTM is an optimisation model with a target function to minimise annualised system costs. Today, Lapland operates a near #100RE power system.

Christian Breyer @christianonre.bsky.social · 1d

5/ Despite this growing interest, there's a research gap in understanding the techno-economic feasibility of RE in remote Arctic regions like Lapland, which possess rich onshore wind power but limited low-cost solar PV potential.

Christian Breyer @christianonre.bsky.social · 1d

4/ EU needs considerable amounts of e-fuels, maximising domestic production in regions with abundant renewable resources, like the Nordics. This enhances energy security & reduces dependency on external suppliers. Such regions leverage low-cost power for domestic fuel production.

Christian Breyer @christianonre.bsky.social · 1d

3/ The EU targets 55% emissions reduction by 2030 & climate neutrality by 2050. However, hard-to-abate sectors, i.e. chemical industry, marine and aviation transport require energy-dense fuels, leading to a significant demand for e-fuels & e-chemicals via a #PtXeconomy

2/ This research belongs to a stream of energy transition research for #Finland: main transition study doi.org/10.1016/j.en... , the role of heat pumps doi.org/10.1016/j.ap... , and the role of new nuclear doi.org/10.1016/j.en....

1/ New @lut.fi study shows that remote, sparsely populated #Lapland can transition to a #100RE system by 2050 doi.org/10.1016/j.en..., becoming a key Arctic energy hub with a very low LCOE of 28.2 €/MWh and can contribute to global defossilisation efforts
