Together, jurisdictions with net zero targets now represent at least:
It was found that already 61% of countries, 9% of states & regions in the largest emitting countries and 13% of cities over 500k in population have now committed to net zero. Of the world’s 2,000 largest public companies, at least one-fifth (21%) now have net zero commitments, representing annual sales of nearly $14 trillion. A majority of these companies also have interim targets, a published plan and a reporting mechanism, with just over a quarter meeting a full set of ‘robustness criteria’.
As Britain works toward reaching net zero by 2050, hydrogen is one solution to decarbonising our gas system. Project Union is National Grid’s development of a hydrogen ‘backbone’ to link industrial clusters around the country.
We are exploring the development of a UK hydrogen ‘backbone’, which aims to join together industrial clusters around the country, potentially creating a 2000km hydrogen network.
Repurposing around 25% of the current gas transmission pipelines, Project Union will build on the government’s 10-point plan to invest more than £1 billion to unlock the potential of hydrogen and support the establishment of carbon capture, utilisation and storage (CCUS) in four industrial clusters.
It’s anticipated that the backbone could carry at least a quarter of the gas demand in Great Britain today, ensuring reliable, affordable and decarbonised energy for homes and businesses.
The project is exploring a hydrogen backbone connecting the Grangemouth, Teesside and Humberside clusters, as well as linking up with Southampton, the North West and South Wales clusters. As the clusters develop, we’ll be ready to join them up.
Using net zero development funding, we are financing a portfolio of net zero projects. One of these is the feasibility phase of Project Union, which will include: identifying pipeline routes; assessing the readiness of existing gas assets; and, determining a transition plan for assets in a way that supports the country’s net zero ambition.
The research will explore how we can start to convert pipelines in a phased approach by the end of the decade, aligning with government ambitions of producing five gigawatts of low-carbon hydrogen by 2030.
Project Union will also look at how to connect the backbone to the existing interconnectors coming into Bacton gas terminal in Norfolk, so allowing the UK to link with the EU hydrogen backbone that is also being developed – this could open up future import and export of hydrogen with European neighbours.
Since I began writing about energy storage in 2013, falling costs have prompted a surge in batteries being installed around the world. Just as silos store excess grain on farms for when it’s needed during lean periods, grid batteries store additional energy so that it can be used to keep the lights on when supply fails to match demand.
Historically, fossil fuels have provided that buffer in the energy system. Coal, oil and gas can be burned whenever needed to keep people driving, heating homes and turning on appliances. But tackling climate change will mean shifting to renewable energy generation – which can be patchy when the sun isn’t shining and the wind isn’t blowing – and swapping gas boilers and combustion engines for alternatives powered by clean electricity.
A new international review of bulk electricity storage technologies highlights the potential of thermo-mechanical energy storage.
Thermo-mechanical energy storage (TMES) technologies can offer a reliable, low-cost solution as grid-scale electricity storage, according to a comprehensive review led by researchers at Imperial College London.
The research, published in Progress in Energy, examines recent progress in the advancement of a range of TMES technologies, including compressed-air energy storage, liquid-air energy storage and pumped-thermal electricity storage.
Using a combined approach comprising validated thermodynamic models and estimates from multiple costing approaches, the researchers compared the technical and economic characteristics of these technologies and assessed their competitiveness against other bulk energy storage options such as flow batteries and pumped-hydro energy storage.
“This is the first time a detailed techno-economic analysis of the main thermo-mechanical energy storage options has been performed for a large range of sizes under a unified modelling framework,” says Andreas Olympios from the Department of Chemical Engineering.
The need for storage
Variable renewable energy sources such as wind and solar now account for just over a quarter of global electricity generation, a share that is growing steadily, creating new challenges for electricity grids.
REA have today published a report into longer-duration energy storage.
The UK will need at least 30GW by 2050, but this target is currently undeliverable based on the present market and regulatory framework.
REA‘s Director of Policy, : Frank Gordon: “It’s clear that, in order to drive investment in this area, a new market mechanism is needed.”
Drax Group CEO, Will Gardiner: “With the right support framework from Government a new generation of pumped hydro storage power stations can be built, supporting new jobs and helping the country decarbonise faster.”

Malta Inc, developer of a grid-scale electro-thermal energy storage technology, has closed a Series B funding round, raising US$50 million from investors that include Facebook co-founder Dustin Moskovitz.
The company claims its solution to the variable generation profile of renewable energy can provide storage of energy at large-scale for up to 200 hours, is scalable and relies on abundant materials, as well as combining processes from already-established and proven industries.
“Malta’s innovative application of well-established technologies and materials could accelerate the roll out of long-duration storage to support the transition to fully dispatchable renewable energy,” Dustin Moskovitz said.
Copenhagen, Denmark – Fast-tracked by advances in technology and increasing customer demand for sustainable supply chains, A.P. Moller – Maersk accelerates the efforts to decarbonise marine operations with the launch of the world’s first carbon neutral liner vessel in 2023 – seven years ahead of the initial 2030-ambition. All future Maersk owned new buildings will have dual fuel technology installed, enabling either carbon neutral operations or operation on standard very low sulphur fuel oil (VLSFO).
“A.P. Moller – Maersk’s ambition is to lead the way in decarbonising global logistics. Our customers expect us to help them decarbonise their global supply chains, and we are embracing the challenge, working on solving the practical, technical and safety challenges inherent in the carbon neutral fuels we need in the future. Our ambition to have a carbon neutral fleet by 2050 was a moonshot when we announced in 2018. Today we see it as a challenging, yet achievable target to reach,” says Søren Skou, CEO, A.P. Moller – Maersk.
Decarbonising heat is key to achieving net zero. Innovators from the Birmingham Centre for Energy Storage are playing a vital role.
Reducing carbon dioxide emissions is, undoubtedly, the key element in our global drive to tackle climate change. The popular imagination is captured by a vision of polluting petrol and diesel vehicles yielding to a utopian vision of electric vehicles propelling us into a cleaner future. Power-hungry factories, offices and homes will be fed a lean-burn diet of electricity generated from renewable and low-carbon sources, such as solar and wind.
As important as electricity is, it only provides part of the overall energy demand within a country. Other energy vectors such as liquid fuels and natural gas typically provide greater amounts of delivered energy (see Figure 1). There is a significant contribution from transportation fuels and an even bigger demand associated with heat, which accounts for some 51% of global energy use.
BCES’ collaboration with Jinhe Energy has already led to a world-first commercial plant, in Xinjiang, which harnesses wind power for heating. Funded by UK EPSRC and the Natural Science Foundation of China, the project has taken wind power that would otherwise have been wasted and converted it into heat. This thermal energy is then stored in cPCM materials and used for space heating on a commercial scale.
