Die Umstellung des deutschen Mietmarkts von Kalt- auf Warmmieten kann den klimafreundlichen Umbau von Mietshäusern fördern und gleichzeitig Mieter vor teuren, ineffizienten Modernisierungen schützen.
agora-energiewende.de/presse/neuigke…
Vorbild ist Schweden, wo seit dem Jahr 2000 eine Kombination aus steigenden CO₂-Preisen bei gleichzeitiger Einführung des Warmmieten-Prinzips gilt. Die Emissionen der dortigen Haushalte sind seither um 95 Prozent gesunken.
Die Vier Voraussetzungen für eine erfolgreiche Wärmewende sind 1) Warmmieten, 2) stetig steigende CO2-Preise auf Brennstoffe, 3) staatliche Förderung, sowie 4) verpflichtende Sanierungsfahrpläne.

One of the more interesting aspects of this very informative new @H2Europe report is its analysis comparing the cost of producing renewable hydrogen for electrolysis projects connected to the grid vs islanded systems with direct connection of renewables.
This table provides an overview of the two schematic production scenarios. For both scenarios, key techno-economic parameters of the electrolysis were adopted based on current state-of-the-art 10,000 kW alkaline electrolysis. Image
For 2019, the study estimates that production costs using grid electricity in the EU (together with Norway and the UK) are in the range of €2.6 – 9.5/kg, with the average for all countries being €4.7/kg and a median of €4.2/kg. Image

The EU Hydrogen Strategy is about scaling renewable hydrogen production to levels beyond current EU consumption levels for conventional fossil hydrogen. At 0.1% of current hydrogen production, we better get to it.
Current hydrogen demand is largely concentrated in a handful of applications, in particular diesel fuel refining and ammonia production for fertilizers.
Most of this H2 production is 'captive', meaning it is produced on site at the location of consumption. Some of it is produced as a by-product of other production processes, such as chlor-alkali production or coke oven gas. A small share is from separate 'merchant' producers.

THREAD: AGRICULTURE, WASTE & NON-CO2 EMISSIONS

1/ The last two weeks I unpacked 2030 energy sector results in the @EU_Commission's new EU 'Long Term Strategy' and took a closer look at Buildings, Industry, Transport. Today, I cover what remains.

2/ Energy related emissions account for 79% of EU GHG emissions and includes the production of electricity & heat generation, and fuel combustion in industry, buildings, transport & agriculture. Other GHG emissions come from agriculture, waste & non-energy industy processes.
3/ Agriculture, Waste and Non-energy Industry also make up the other main sectors in the 'Non-ETS' Sectors outside of the scope of the EU Emissions Trading System, aside from the Transport & Buildings Sectors.

THREAD: SECTORAL DEEP DIVE - TRANSPORT IN 2030

1/ Recently I highlighted key 2030 energy modelling results in the @EU_Commission's new EU 'Long Term Strategy' and did deep dives on Buildings & Industry. Today I take a closer look at the Transport Sector.
2/ Transport represents around a third of the final energy consumption in the EU. All sectors have seen emissions reductions since 1990, with the exception of transport, which has increased by nearly +25%. The currently dominant transport technologies rely on oil based fuels.
3/ Decarbonizing the transport sector will require an integrated approach: 1) increasing vehicle efficiency, 2) promoting low- and zero emission vehicles and infrastructure, 3) fuel switch to alternative and net-zero carbon fuels for transport and 4) electrification of transport.

THREAD:

1/ The EPSC - the European Commission's @ECThinkTank - has launched a new report on key trends shaping climate & energy policy in the short- to medium-term (2025-2030). The publication is aimed at laying the groundwork for upcoming discussions on stronger implementation.
2/ The publication identifies 10 key trends in total, which I will try to summarize here in condensed form. However, I encourage you to also take a closer look at the publication and follow @EPSC @phil_offenberg @AndouraSami if you are interested in digging deeper.
3/ Trend 1: The impacts of climate change are real in the EU today, no longer a distant threat.

Global warming has already reached 1°C above preindustrial levels and is increasing at approximately 0.2°C per decade leading to weather-related disasters (€290 bn in losses '17).

THREAD: SECTORAL DEEP DIVE - INDUSTRY IN 2030
Last week I highlighted key energy modelling results for 2030 in the @EU_Commission's new EU 'Long Term Strategy' and did a deep dive on Buildings. Today I want to take a closer look at the Industry Sector. 1/
While energy industries (incl. power) and buildings have each seen emissions reductions of roughly -25% between 1990 and 2015, industrial energy-related emissions decreased significantly more in relative terms (-42%), at least until flattening out at around 2012. 2/
Important factors include 1) energy efficiency improvements, 2) fuel switching to biomass, 3) closure of capacity and structural shifts, and 4) deep reductions of non-CO2 GHG emissions. Energy intensity across all industrial sectors together declined by nearly 40%. 3/
