UK Hydrogen Strategy - the clean fuel of the future

The-UK-Gov-Hydrogen-Stragety-CoverPost

In August 2021, the UK government released its Hydrogen Strategy focused on fast-tracking a thriving clean hydrogen economy to deliver 5 GW production by 2030. Low carbon hydrogen is essential if the UK meets Carbon Budget Six by the mid-2030s and net-zero by 2050.

IPCC 2021 report on climate change - just time to avert catastrophe

IPCC-Climate-Change

Even the most avid climate change sceptic must have moved their position somewhat in the light of the devastating weather events we have experienced over the last few years. Record-breaking rainfall and temperatures do not in themselves prove the climate is changing, yet they are a good indication that something quite frightening is happening to our weather. This is a brief outline of the IPCC sixth assessment report "The Physical Science Basis" released in 2021.

Reducing CO2 emissions - will COP 26 help?

Glasgow-City-COP26-EnergyEfficiencyWE_20210826-121229_1

COP26 – the 26th meeting of the Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) – will be held in Glasgow during November 2021 and hosted by the UK in partnership with Italy. Delegates will address the extent to which world leaders have achieved the aims of the Paris Agreement and set new targets for the coming years. So how effectively will COP26 help reduce carbon emissions?

Non-domestic rented buildings in England and Wales will need to meet strict energy efficiency standards of an EPC Band B by 2030

England-EPC-Grade-B-by-2030web

In line with its plans to reduce all UK greenhouse gas emissions to net-zero by 2050, the UK government is getting tougher on landlords of non-domestic rented buildings in England & Wales over EPC (Energy Performance Certificate) regulations. Landlords must ensure that all buildings in that category meet EPC Band B by 2030 regardless of when they were rented. Exactly how the new regulations will be implemented is still under consultation, and the government is accepting responses from all stakeholders, including landlords, tenants, local authorities and suppliers. This is likely to have big implications for commercial landlords and tenants.

Scottish New Build Heat Standard

New-Build-Heat-Standard

Scotland is making substantial inroads in decarbonisation and tackling climate change. The country aims to reduce greenhouse gasses emissions to net-zero by 2045 and reduce them by 15% by 2030. Already 90% of Scotland's electricity supply is from renewables, and, encouraged by current progress, the Scottish Government is now focusing on reducing emissions from heating buildings and is heavily targeting new buildings.

E.ON converts natural gas pipeline in Germany to pure hydrogen

Hydrogen for heating E.ON converts natural gas pipeline to hydrogen for heating

Replacing natural gas by hydrogen for heating domestic residential and commercial buildings would have a massive impact on greenhouse gas emissions and reducing global warming. There is, of course, the important caveat that the hydrogen manufacture must be powered by renewable resources. There is no fundamental reason why this cannot be achieved, but there are significant challenges in doing so.

Fife homes to be heated by world-first green hydrogen heating network

Metro-Blog-hydrogen-gas-networks-text Hydrogen network for Fife homes

If we could replace our standard central heating systems with a carbon-free solution, we would have the potential to reduce UK greenhouse gas emissions by as much as a third. Source: OFGEM. This would go a long way towards meeting the UK and Scottish governments net-zero targets. 

One solution is to replace natural gas-fired boilers with hydrogen fired boilers and produce the hydrogen using renewable resources.

The coronavirus pandemic and climate change

Coronavirus-and-Climate-Change-Web The coronavirus pandemic and climate change-what have we learned?

The skies are bluer, there are virtually no con-trails creating cloud cover, and the air smells so much cleaner. It's just like the olden days that our grandparents would wax nostalgically about. Doubtless, the shutdown has improved air quality in our cities, and the effect is global. But is it just a blip or will it have a long term impact on health and climate change?

Climate Change in Rich Countries

Climate-change-in-rich-countries Climate change in rich countries
While extreme weather events have their most significant impact on poorer vulnerable countries, rich countries are experiencing the effects of climate change to an increasing extent. The exposure and vulnerability of countries to extreme events are indicated by the Global Climate Risk Index (CRI) published by Germanwatch. This focusses on both fatalities and economic losses. Perhaps surprisingly, some of the world's richest countries appear high on that list. For instance. For the year 2018, Germany, Europe's most prosperous country, was ranked third on the CRI scale, Japan and The Philippines filling slots one and two respectively.

Decarbonising gas - a solution to meeting zero-emission targets

Decarbonising Gas A solution to meeting zero-emission targets
​The UK Government has committed to net-zero carbon emissions by 2050 with the Scottish Government having committed to become net zero by 2045. This includes decarbonising heating and hot water generation, which currently account for around a third of UK's total greenhouse gas emissions. There are two feasible options: full electrification of all h...
